Sentry (Robert "Bob" Reynolds) is a fictional character and superhero appearing in American comic books published by Marvel Comics. The character first appears in The Sentry #1 (September 2000),[1] and was created by Paul Jenkins and Jae Lee with uncredited conceptual contributions by Rick Veitch.[2]


In the late 1990s, Paul Jenkins and Rick Veitch developed an idea by Jenkins' about "an over-the-hill guy, struggling with an addiction, who had a tight relationship with his dog" into a proposal for Marvel Comics' Marvel Knights line. Jenkins conceived of the character "a guardian type, with a watchtower", and came up with the name "Sentry" (after previously considering "Centurion"). Veitch suggested that the character could be woven into the history of the Marvel Universe, with versions of the character from the 1940s depicted in artistic styles matching the comics of each period. Veitch also suggested that due to some cataclysmic event, all recollection of the Sentry would have been removed from everyone's memory (including his own). Jenkins and Veitch decided that they would create not only a fictional history for the Sentry within the Marvel Universe, but also a fictional publication history in the real world, complete with imaginary creators ("Juan Pinkles" and "Chick Rivet", anagrams of Paul Jenkins and Rick Veitch). Jenkins pitched the concept to Marvel Knights editor Joe Quesada. Quesada decided to commission a miniseries written by Jenkins with art by Jae Lee, with whom Jenkins had previously worked on an Inhumans miniseries.[2]

Publication history[]

The Sentry was first introduced in his eponymous Marvel Knights 2000 miniseries written by Paul Jenkins with art by Jae Lee.[3] The miniseries ran for five issues and then segued directly into a series of flashback one-shots in which the Sentry teamed up with the Fantastic Four, Spider-Man, Angel of the X-Men, and the Hulk. These one-shots led to The Sentry vs. the Void, an additional one-shot that wrapped up the story of the miniseries and one-shots. In 2005, writer Brian Michael Bendis reused the Sentry by making him a member of the New Avengers. The Sentry played a minor role in the first arc, Breakout (issues #1–6), and was the focus of the second arc, The Sentry (issues #7–10) : Jenkins himself was featured as a character in the second one. Also in 2005, the Sentry received another miniseries, written by Paul Jenkins and drawn by John Romita, Jr., which ran for eight issues. The Sentry appeared in The Mighty Avengers as a member of that team, and later in Dark Avengers in a similar capacity, and as protagonist in The Age of the Sentry miniseries. He appeared as a regular character in the Dark Avengers series from issue #1 (March 2009) until the time of his death in the Siege limited series.

On March 6, 2018, it was announced that the character would be given an ongoing series written by Jeff Lemire and with art by Joshua Cassara and Kim Jacinto.[4] The series ended after five issues.

Fictional character biography[]

Sentry and the Marvel Universe[]

Cover art to The Sentry #2 by Jae Lee (line art) and Jose Villarrubia (painted colors).

Middle aged, overweight Bob Reynolds remembers that he is the Sentry, a superhero whose "power of one million exploding suns" derives from a special serum. Realizing that his archenemy the Void is returning, Reynolds seeks out several prominent Marvel characters to warn them and to discover why no one remembers the Sentry.

The characters' memories of the Sentry and the Void resurface when Reynolds talks with them. The Sentry had taught Angel how to conquer his fear of falling. Peter Parker's photograph of the Sentry earned him a Pulitzer Prize and fame. Hulk had never forgotten the Sentry, whom he called "Golden Man". Under the Sentry's influence, Hulk had been a force for good which had redeemed his violent actions and won the adoration of the public. Mister Fantastic remembered the Sentry was his best friend and that the Fantastic Four had teamed up with him on many adventures. Meanwhile, the general public gradually came to remember the Sentry, as did Reynolds' old sidekick, Billy Turner who was formerly known as the Scout (now scarred and missing a forearm, due to an attack from the Void).

During the course of his investigation, Reynolds and Mister Fantastic discovered what had happened: as the Void had threatened the Earth, the heroes learned that the Sentry and the Void were two halves of the same person. In order to save the world, Robert Reynolds erased his memory from the mind of nearly every person on Earth, even his own. As the heroes stood along the United States' East Coast, united against the coming Void, Reynolds realized that he had to make the sacrifice again. With the help of his mechanical servant CLOC, Mister Fantastic, and Doctor Strange, Reynolds erased the Sentry from the world's memories once more. However, in the final panels of the final one shot, it's left ambiguous as to whether or not Reynolds actually remembers who he is despite Richards' and Strange's work.[5]


Reynolds reappears inside the supervillain prison the Raft, voluntarily imprisoned for murdering his wife Lindy Lee. Electro shuts down the security system, causing a massive jail break in which 42 villains escape. Several of the escaping villains are caught, while Matt Murdock is entering to talk to the Sentry. The Sentry defends several other characters from Carnage, whom he flies to space and rips in half.[6]

Eventually, the Avengers learn that Mastermind, under the direction of an enemy of the Sentry known only as the General, implanted a psychic "virus" in Reynolds' mind that created delusions and the existence of the Void, which is actually Reynolds' repressed persona. The virus impairs Reynolds' ability to remember his life accurately, and, as a cry for help, he subconsciously implants his memories into the mind of comic book writer Paul Jenkins, who then transferred those memories to comic books. The Avengers track him down and show him that his wife, who he confessed to murdering, is alive and well. The Sentry flees, and he finds himself waking up in the small suburban house he shares with Lindy. His appearance has changed in an instant, and he appears to be living the life of an ordinary man. But the Avengers have tracked him down again, and, with the support of The Fantastic Four, the X-Men, the Inhumans, Namor, Doctor Strange, and S.H.I.E.L.D., they confront and attempt to reason with him. But Robert tearfully insists that the Void is coming, who will destroy them all, and that he can't help it. The Void arrives, a separate entity from Robert, and it takes on several different monstrous forms as it attacks. Though a vicious battle ensues, no one is actually killed. As they are still having their dialogue, and start getting through to him, the Void slows down to a stop. Finally, the powerful telepath Emma Frost is able to release Reynolds from the virus and restore his memories, and the Sentry joins the Avengers. The world in general, however, does not regain their memories of the Sentry or the Void. In an astounding coincidence, or twist of fate, the Sentry's Watchtower appears atop Stark Tower, where it had been all along. "Guess I was hiding it as part of my crazy," Robert explains.[7]

The Sentry, returned as a hero, captures the hearts of the public while newspapers refer to him as "the Golden Guardian of Good", and he saves hundreds of lives on a daily basis.

Reynolds' psychological problems, however, have worsened. Unable to reconcile that Robert Reynolds, the Sentry, and the Void are the same being, the Sentry contains the Void in a vault in the Watchtower. At CLOC's urging, Reynolds' psychiatrist Dr. Cornelius Worth enters the vault and finds only a chair and a mirror. Dr. Worth realizes that the Void is not imprisoned at all. Later, during an office visit, Cornelius confronts Robert with this fact, showing him newspaper articles that indicate that the Sentry's heroic exploits are seemingly balanced in equal measure to other horrific deeds committed by the Void. Dr. Worth asked Robert to manifest the Sentry, so he can speak to him, but Robert refuses. Reynolds becomes angry and confused, changing forms back and forth between the Sentry and the Void, before leaping through (and breaking) an office window. Dr. Worth follows Robert, finding him at the fairgrounds where he first gained his powers. The fairgrounds have been destroyed, and all the patrons evacuated, running out screaming.[8]

Dr. Worth confronts Reynolds, who is holding a gun, and Reynolds warns the doctor to leave. Dr. Worth is undeterred, asking Reynolds to put the gun away, advising that he knows that Reynolds, despite his actions as the Void, is still trying to do good. Reynolds then simultaneously manifests both his Sentry and Void personas, who split into two separate entities. Notably, when the Void peels back his pitch black mask, his face is that of Robert Reynolds. Reynolds tells Dr. Worth that he was always the Void, indicating that the Void is actually Reynold's true persona, and describes the Sentry as a separate entity. Having revealed his deepest secret to Dr. Worth, Reynolds (still in his Void persona and holding a gun to Dr Worth's head), tells him that he must kill him now. Holding the gun just inches away from Dr. Worth's temple, Reynolds mockingly asks the Sentry if he is faster than a bullet. And with that he pulls the trigger and fires the gun at Dr. Worth.[9]

After a bright muzzle flash, Dr. Worth notices that he is still alive, and the Sentry, having seemingly remained still, opens his hand to reveal the fired bullet. The Sentry chides Reynolds that he knew Sentry was fast enough to stop the bullet from reaching Dr. Worth's head and that the entire ploy was in vain, with Reynolds never intending to hurt Dr Worth after all. Reynolds dons the Void's black mask/visage, and accuses the Sentry of lying, declaring at first that Sentry isn't real, and then ranting that Sentry is the true manifestation of Robert Reynolds. The Sentry, addressing the Void as Robert, points out that Robert created the Sentry to tell no lies, and further clarifies that Robert hired Dr Worth so that he could bring his secret out in the open to justify destroying the world. The Void then attacks the Sentry, and the two fly up into the sky.[10]

As Dr. Worth is watching the two entities fight in the air, the Sentry appears standing behind him, with cuts and bruises on his face and no further sign of The Void. The Sentry explains to Dr. Worth that Reynolds hired him because he subconsciously wanted someone to reveal that he is the Void to the world, so he would no longer have to hide that truth. Dr. Worth asked the Sentry if he too is Robert Reynolds, but the Sentry advised that he is merely an aspect of Robert. Cornelius then asked him to clarify which of the two aspects (The Void or the Sentry) is the real Robert Reynolds. The Sentry explained that neither he, nor the Void, represent the entirety of Robert Reynolds, as the two aspects do not even share memories. The Sentry then tells Dr. Worth how Reynolds really gained his powers as a teenager: by stealing the Professor's serum and ingesting it to get high. He also pretended to be insane, knowing all along that the Void was never really in the Watchtower's vault, so that Robert Reynolds would keep the Void dormant, and also not wipe Sentry from existence. Dr. Worth tells the Sentry that he is not sure if Robert Reynolds can still do that. The Sentry then bids Dr Worth farewell, telling him that he's going to seek out help to answer his existential questions.[10]

The Sentry then flies off and meets up with Doctor Strange. Doctor Strange uses his magic to peer into Sentry's memories and his life force. Doctor Strange finds that Sentry's life force is incomplete. While Strange and Sentry dialogue, a third voice can be heard speaking – though only the Sentry can hear it. The third voice tells Sentry that he is not real, and that he does not exist. Doctor Strange, oblivious to the third voice, peers deeper into the Sentry's memories, and reveals that even the Sentry's own understanding of his origins are flawed. Doctor Strange finally uncovers a deep memory of a secret fortress-like building, that Sentry recognizes as the Professor's base of operations. Doctor Strange, suddenly overcome by panic and fear, shuts down the magic mind probe and begs the Sentry not to pursue this any further.[10]

The Sentry determines to seek out the base revealed in Doctor Strange's magic mind probe, as he can still hear the third voice telling him that "none of this is real". Before Sentry embarks on his journey, he returns to Dr. Cornelius Worth's home, posting Watchdog to guard the doctor's family and Lindy Lee, who is present at the home as well. Sentry wonders if he is truly Lindy Lee's husband, as he may not be the true Robert Reynolds. Dr. Worth begs Sentry to heal his sick daughter, who is in a catatonic state. Sentry declines his request, citing that if he showed preference for Dr. Worth's daughter, he would ethically have to do this for everyone. Sentry sets off to find the base and, after a short moment, Dr. Worth's daughter comes out of her catatonic state and speaks to her father – shocking the doctor, who realizes that Sentry had healed her anyhow.[10]

The Sentry finds the base in his memories, but it is destroyed. As he enters, the third voice in his mind grows louder and louder, telling him that none of this is real, that he is a murderer, and that he is not a hero. As he enters the base, the Sentry suddenly finds himself sitting in locked, padded room, frothing at the mouth, and in a straitjacket. Suddenly, a man's voice through a loud speaker tells him that he is a mental patient who has undergone shock therapy and has awakened from a deep slumber, and that his name is John Victor Williams.

Sentry is told that his memories are false, and that he is, in fact, a crazed patient who brutally killed his next door neighbor, Melinda Jensen – whom the Sentry at first recognized as his wife Lindy Lee. After a time, the Sentry seemingly accepts this new version of reality, believing himself to possibly be John Victor Williams, and a prisoner in a psychiatric care facility. The Professor is at the facility, treating him as his doctor. Sentry, now appearing in the body and form of Robert Reynolds, manifests aspects of his old memories, which the Professor dismisses as part of his delusions. Eventually, Sentry realizes that this version of reality is entirely a false mental construct, and that in reality he is strapped to a table, locked in a machine that is keeping him sedated and implanting these false memories. Sentry breaks out of the machine, and sees that he is deep inside the base he had sought out – which turned out to be a secret S.H.I.E.L.D. facility. Nick Fury is present, as is the Professor and Doctor Strange, who was revealed to be the author of the false mental constructs. Doctor Strange tries to explains that he was doing this for Sentry's own good, but Sentry refuses to hear it. He grabs the Professor, begging for an explanation. The Professor reveals that he has a thermo-nuclear device implanted inside him that will detonate if he reveals the true secret of Sentry's origin. When the Professor decides to tell him, Nick Fury activates the bomb, forcing Sentry to fly the Professor up into the stratosphere. Before the Professor detonates, he tells Sentry to seek out the Void in Antarctica, advising that the Void knows the truth. The Professor dies in the explosion, and the Sentry heads back to Earth, heading for Antarctica.[11]

In a final battle at the Void's base in Antarctica (which he calls the 'Hidey-hole' ... the opposite of the Watchtower, just as COLC, its 'Computer for Obliterating Life Completely', is the opposite of CLOC), the Void claims that Reynolds had actually ingested a super-saturated, exponentially more potent version of the Super-Soldier formula that created Captain America. This was considered dangerous by the government because the Sentry's blood could be used to create more of the serum, enough for the entire world. Several failed attempts were made to kill him. Enraged by this revelation, the Sentry throws the Void into the Sun, telling his enemy that he no longer needs him to balance his own actions of good. The Void promises to return.[12]

Next, Yelena Belova attacks the Avengers and absorbs the Sentry's powers. After Belova defeats each of the Avengers, she is defeated by the manifestation of the Void, which envelops and incapacitates her. The Sentry tells Belova that absorbing his powers has exposed her to the Void, but if she answers his questions, he can send the Void away.[13]

The U.S. government sends Sentry to apprehend Iron Man, who has been mind-controlled to assassinate a number of high-profile former terrorists. Unable to find any physical weaknesses or outrun the Sentry, Iron Man attacks the Sentry's mind; he remotely hacks CLOC and has Sentry barraged with unfiltered warnings about multiple devastating disasters occurring simultaneously throughout the world. Unable to prioritize which alarm to deal with first, Sentry collapses to the ground in tears, utterly incapacitated.[14]

Civil War[]

The Sentry sides with Iron Man's Pro-Registration program. He has been seen in a promotional poster labeled "Civil War: The Final Battle," again on Iron Man's side. He accompanies a S.H.I.E.L.D. squad to battle Wolverine and tells him that he doesn't want to get involved but sees no choice; he claims he has to stop the ugly business even if that means becoming part of it for a while. He then knocks Wolverine unconscious and hands him over to S.H.I.E.L.D.[15]

Trying to escape from the battle, believing that every path he can choose will ultimately lead to the death of people he knows (one of his thoughts at this point consists of himself and Hulk triumphantly returning to Earth and 'ending' the war via killing all the heroes), Sentry retreats to the moon, where he is confronted by the Inhumans living there. Believed a threat, he is ordered to follow them to Black Bolt's presence. Then after a discussion of the Civil War events with the (still unaware) Inhumans, he rekindles his friendship with them and almost resumes his past relationship with Crystal. He is then confronted by Iron Man himself who finally convinces a still reluctant Sentry to join him.[16]

It is stated that the Sentry publicly announces his support of the Registration Act three days after the climactic battle of the Civil War limited series.[17]

Mighty Avengers[]

The Sentry is recruited by Tony Stark to be part of the Mighty Avengers, the newest incarnation of the Avengers team. While at first there is some dispute between the Sentry and his wife, Robert joins the team while Tony Stark and Ms. Marvel offer him assistance to battle his mental issues. He is described to be the most powerful member of the team, but lacks proper training on how to use his abilities, usually apologizing for his mistakes (apologizing for damage to a building and being thrown into a blimp).[18]

In the battle against the female Ultron, the two prove to be evenly matched. Neither is able to win until Ultron uses a virus to down Stark's Helicarrier. Ultron then initiates "Plan B" and kills Lindy, the Sentry's wife.[19]

An enraged Sentry attacks Ultron once more. In an exchange of blows, Sentry is knocked away as Ares and Ant-Man proceed to infect Ultron with a virus intended to destroy it. Soon after, Sentry once again attacks Ultron, almost compromising the Avengers plan, nearly destroying Ultron by tearing its head off. Before he can finish, he is knocked away by Ms. Marvel. After Ultron's defeat he returns to the Watchtower to find his wife Lindy alive and well—having apparently revived her himself. Stark is later shocked when a terrified Lindy secretly requests that he find a way to either depower or kill her husband.[20]

The Sentry then aids the team when they attack Latveria but ends up stuck in the past with Doctor Doom and Tony. He is amazed to see his former self and the Void. He angrily attacks Doctor Doom until Tony explains what has happened. The Sentry finds them and Stark sends Bob into the Baxter Building so that they can use Mister Fantastic's time machine; since all memory of his past actions were erased by his 'spell', he can do anything in the past and be sure that it won't impact the present. The Sentry gets to it, first having to deal with the Thing, whom he easily defeats. After he returns to present time along with Iron Man, he finds the rest of the Avengers engaged in battle with Doctor Doom. The Sentry quickly subdues Doom, who is then taken into S.H.I.E.L.D. custody.[21]

World War Hulk[]

A confrontation between Iron Man and the Hulk ends up with Sentry's Watchtower being dropped straight down through Stark Tower/Avengers headquarters, destroying it.[22] Mister Fantastic tries to build a machine that will cast a projection of the Sentry and recreates his calming aura, hoping that it would calm the Hulk, but the Hulk sees through the illusion.[23]

Later in a confrontation between the Hulk and the Fantastic Four, Invisible Woman tries to call the real Sentry for help, but he does not answer the call and is sitting in his apartment watching television. The President of the United States tries to convince the Sentry to fight against his longtime friend the Hulk. The President stumbles over the pre-fed words of persuasion and tries to improvise a plea for help. The Sentry refuses.[24]

After the Hulk turns Madison Square Garden into a gladiatorial arena and forces Illuminati members Mister Fantastic, Doctor Strange, Black Bolt, and Iron Man to fight one another, the military turns to the Sentry for help once again. The Sentry admits to his fear of his tremendous power mixed with his agoraphobia, stating,

It's the agoraphobia. Some days it's...I can't...Sorry, Tony. You'll have to handle this one yourselves.
Against an opponent this powerful...The amount of energy I'd have to expend...if I...lost control, for even a millisecond...

After watching the events on TV and witnessing the Hulk apparently deciding, in Roman-style, to force Mister Fantastic to kill Iron Man, he leaves his home stating that, "It's time to play god".[25]

The Sentry engages the Hulk who is now strong enough to destroy the Earth in his stampede, and unleashes his power. During the prolonged fight they both expend massive amounts of energy, nearly destroying Manhattan and disintegrating entire buildings. Sentry begins to lose control and Banner is forced to stop him before the energy Sentry releases consumes the city. After Banner delivers the final punch, the broken-faced Robert Reynolds thanks him before immediately collapsing before his feet, both reverting to human form.[26]

Secret Invasion[]

When a Skrull spacecraft is discovered approaching Earth's atmosphere, the Mighty Avengers and New Avengers simultaneously head to its predicted crash area in the Savage Land. Inside are numerous superheroes dressed in their old costumes. As the Sentry fights one who looks like the Vision, it transforms into the Void, blaming the entire situation on the Sentry's hidden desires. Panicking, the Sentry flees.[27] At the same time, a full-scale Skrull invasion begins, with the Watchtower where Lindy is being attacked by a Defenders-themed Super-Skrull. Before he can attack however, the Void appears, defends Lindy, and tells her that the Sentry can't handle the situation and that "Whatever he can't do, I can."[28]

Dark Avengers[]

Sentry joins the Dark Avengers, Norman Osborn's personal team of Avengers, stating that Osborn is helping him in return after Osborn confides his own mental deficiency in Bob.[29] Upon confronting the sorceress Morgan le Fay, the Sentry kills her only to have her come back to life and kill him in turn.[30] After the Dark Avengers and Doctor Doom defeat Morgan, the team returns to New York City to find the Sentry reappears alive and well.[31] After a terrorist attack by an Atlantean cell, Norman Osborn demands to speak to the Void and tells him to kill all the terrorists. The Sentry obliges but is seen with black eyes, indicating the return of the Void within the Sentry persona.[32]

When anti-mutant riots break out in San Francisco, the Dark Avengers and H.A.M.M.E.R. move in to contain the situation. The Sentry watches as the riots are quelled, when the Dark Avengers team up with Norman's Dark X-Men against the X-Men, Emma Frost frees the Void from Sentry to take him off the battlefield. However, a sliver of the Void becomes contained in her mind, forcing Emma to shift into her diamond form to keep it contained. When Psylocke, Professor X, and Cyclops attempt to help Emma, she subsequently passes the Void sliver to Cyclops, whom the Void felt could be of more use to it. However, after years of dating and being married to the world's most powerful mutant telepath Jean Grey, Cyclops uses all that she taught him to successfully lock the Void inside an unbreakable psychic prison within his own mind.[33]

When Sentry returns to Avengers Tower, Lindy shoots him because she fears his mindset, but he returns unharmed.[34]

The Avengers are sent to investigate disappearances in Dinosaur, Colorado, and the Sentry is disintegrated when he approaches the area.[35] The team find that Molecule Man, secluding himself, is responsible. Reece is losing touch with reality, and struggles to differentiate between the real and his creations. After the other Dark Avengers have been defeated, Osborn's aide Victoria Hand convinces Owen to restore reality in order to be left to his own devices. The Sentry returns mid-conversation and attacks Molecule Man only to be destroyed again. The Sentry reforms once more, but this time under the Void's influence. When a missile distracts Owen, Sentry takes control of Reece's body and tells Owen to restore reality or die. Reece seemingly obliges him, but is killed, which causes Bob/Void to believe they cannot die. Bob regains control of his body, but doesn't seem to recall killing Molecule Man. Ms. Marvel muses that the Scarlet Witch's reality-rewriting nervous breakdown was negligible in comparison to the threat posed by the Sentry losing control.[36]

Sentry finds a runaway Noh-Varr in the streets of Manhattan. A battle breaks out and Sentry is distracted when a girl named Annie uses one of Noh-Varr's weapons. This creates enough time for Noh-Varr to get away.[37]

After shooting Robert, apparently killing him, Lindy records the Sentry's origins as a drug addict (previously revealed) and that he found the Professor's super-serum by accident. After drinking the serum Bob accidentally destroyed the lab, killing his partner and two guards. As the Sentry, Bob lives a hero's life, forgetting about his past as a thief and addict, blaming them on "a boogeyman" that would become the Void. Lindy knew that Osborn's orders and replica of the serum were unlocking the Void again (Osborn calls him "his secret weapon"). When Bob recovers, his Void persona tries to kill Lindy while claiming to be Galactus, only to be stopped by the Sentry one, who tries to destroy the Void (and himself) in the Sun, only to survive and be convinced to return home.[38]

Upon his return, the Void has now taken control of Robert's body. With black tendrils raining from the sky, the Void severely damages multiple buildings, killing some innocents. As the Iron Patriot, Osborn flies to the Void, claiming that he was breaking their "deal". Norman then has Bullseye murder Lindy.[39]


During the 2010 storyline "Siege", when Osborn attacks the city of Asgard, Sentry, who serves Osborn, is pitted against the Avengers and others who rebel against Osborn. At Osborn's request, the Sentry destroyed Asgard.[40] The Void then takes complete control, Sentry kills Ares much to the surprise of the combatants.[41][42] After defeating the entire Avengers contingent, Sentry is eventually reverted to human form following Loki's revival of the Avengers using the stones of Norn. He then asks to be killed and following a brief outburst from the Void, his wish is granted by Thor.[43] Thor respectfully carries Reynolds' body to the sun and cremates him there.

At a memorial service for Bob Reynolds, CLOC remarks he would rebuild the Watchtower (which vanished at the moment of Bob's apparent death) at an undisclosed location in preparation for the return of the Sentry, and that no one would be allowed to approach it. CLOC then gives Mister Fantastic the Sentry's diary and instructs him to read the final sentence of page nineteen, the contents of which Reynolds knew that only Mister Fantastic would understand. When asked about it, Mister Fantastic keeps the information to himself.[44]

Horseman of Apocalypse[]

The Sentry is later resurrected by the Apocalypse Twins, who use a Celestial Death Seed to transform him into a member of their new Horsemen of Death.[45] The Sentry claims he became trapped in the sun after his previous death at Thor's hands, dying and regenerating over and over again, and that the Void became 'bored' and has left him. He attacks the Avengers and initially captures Thor,[46] but in a later confrontation is stymied by a sand worm controlled by Wasp.[47] After the defeat of the Apocalypse Twins, the Sentry takes the dead body of the Celestial Executioner and offers to take it into deep space, far away from Earth. Wasp states that Sentry is trustworthy as he now views himself as the cosmic protector of humanity.[48]

Marvel Legacy[]

It is revealed that Doctor Strange cured Robert from his condition and put the Void into a chamber of his Sanctum Sanctorum. When Loki became the new Sorcerer Supreme, Stephen asked the Sentry for help, now residing on the top of a mountain.[49] Because of Loki's curiosity about the chamber, Stephen opens it, unleashing the Void.[50] This causes the Void to possess Doctor Strange; however, with the replenishment of his magic by Loki and the help of the Sentry, Strange is freed by his influence and together they lock-in the Void again. An angry and distrustful Robert hits Strange, telling him to leave him alone.[51]

It is later revealed that Doctor Strange created a device called the Confluctor that created a pocket dimension where Robert Reynolds can go to once every 24 hours to be the Sentry and fight the Void with Scout and Watchdog. This will prevent him from turning into the Void in the real world. Robert confides in Billy Turner (formerly The Scout) about the pocket dimension. Unbeknownst to him, Billy devises a plot with one of Sentry's oldest enemies Cranio to duplicate the Sentry formula and trap Robert Reynolds in the pocket dimension, so Cranio can rule there and Billy will be the new Sentry.[52] The plan is foiled when S.H.I.E.L.D. and Iron Man arrest Robert Reynolds for not checking in on his "parole", but he unleashes the Sentry and escapes. Billy takes the Sentry formula and battles Reynolds. They are evenly matched until Reynolds while in his subconscious thoughts decides to stop fighting the Void and become one with him. The newly-merged Sentry easily kills Billy, then removes Cranio from the pocket dimension. Iron Man returns with the Avengers, but they are unable to stop the new Sentry. As Reynolds prepares to leave, Iron Man asks if they're supposed to simply trust he'll do the right thing from now on. Reynolds replies "You don't have a choice" and flies off into space.[53]

During the "King in Black" storyline, Sentry returns in his golden appearance and has been called by the Avengers to help fight Knull. He attempts to fly Knull into space, as he had done to Carnage, only for Knull to break free and tear Sentry in half instead, absorbing the Void emerging from Sentry's body, into his own.[54]

Powers and abilities[]


The Sentry's powers ostensibly derive from a serum that moves his molecules an instant ahead of the current timeline. This was designed to be a hundred thousand times stronger than the original used on Captain America, and was modified by Weapon X.[40] However, in "The Age of the Sentry" mini-series, it is suggested that the Sentry is a sentient life-force, a refugee from another universe which attempted to break through to another one for its new home, and that this was merely accommodated by the serum.[41]

Although the character's exact abilities and their limits are unknown, he has been shown to lift a Helicarrier (with assistance from Ms. Marvel and Wonder Man);[42] effortlessly defeat and break the handle of the axe of Terrax,[40] a herald of Galactus shown as powerful enough to slice planets in half (although at the time Sentry fought him, his full power level was not evident);[43] severely pummel and nearly tear apart the female Ultron,[44] and easily shatter shields of Doctor Doom.[14] During the Sentry's initial miniseries, Spider-Man, in a moment of reflection, recalls that the Sentry fought and stalemated Galactus at one point.[45]

He generally greatly restrains his full power,[46] but when unleashing it he has even overloaded the Absorbing Man;[46] and fought an extremely enraged Hulk for a prolonged time until both fighters reverted to their human forms, whereupon Reynolds collapsed.[19][47] He possesses superhuman speed, making him easily able to evade or catch bullets; and through flight he can travel to the sun and back in a matter of minutes. The Sentry is also apparently invulnerable: Spider-Woman's venom blasts, capable of killing even superhumans at full power, have no effect upon him.[48] Nick Fury has stated that S.H.I.E.L.D. has not yet found a way to kill the Sentry, and Iron Man's scanners have found no physical weaknesses in his body.[citation needed]

The Sentry also has superhumanly acute senses, as he once told an opponent that he could see his nerve centers. He can emit light, which can be used for a pacifying effect, and possesses powers of tremendous energy projection, from both his hands and eyes,[49] capable of harming even the Hulk (in his Green Scar incarnation), who has withstood the equivalent of solar flares unharmed,[19] and also released planet destroying energy against Genis-Vell. The Sentry has also at times demonstrated the ability to instantly teleport himself away in a blinding flash of light.[50][51]

He was once able to implant his memories inside another person's mind, and uses his allegedly vast mental powers to hold his physical form together. After Ultron murdered his wife, Sentry was able to resurrect her by simply touching her.[44] His main weakness may be that he's been shown as susceptible to mental manipulation.[14]

The Sentry has demonstrated the ability to recreate himself after bodily destruction, up to and including total molecular destruction within seconds (he once tried to commit suicide by flying into the heart of the sun). Dialogue between Reynolds and the Void suggests that this particular capability is automatic, involuntary, and beyond the control of either Roberts or the Void.[52]

He eventually found out that all his powers apparently derive from abilities similar to those of the virtually omnipotent Molecule Man, which he uses to take control of the latter's body and resurrect himself multiple times after seemingly being annihilated, but he is not as experienced in manipulating reality yet.[53]

During a conversation between Lindy, CLOC, and the Void, it is hinted that the Sentry's powers may come from a cosmic source, or possibly even from the Judeo-Christian God, with Lindy believing that his powers were of "maybe Biblical proportions" and theorizing that modern-day superheroes were conduits through which such higher power was now being channeled.[31] When Steve Rogers demands that Norman Osborn tell him how the heroes are to stop the Void, Osborn says (albeit possibly figuratively) that the Void was the 'Angel of Death';[35] an earlier Biblical flashback also revealed that the being that brought the divine plagues down on Egypt was apparently similar in appearance to the Void, who, millennia later, claims to the Sentry when attacking New York that doing so is 'God's way'.[31] The Watcher himself confirms that the Void is indeed the "Angel of Death", and it is shown, when fully unleashing its true power, able to easily decimate the Earth and its Moon, and seemingly threaten the cosmos themselves.[54]

As Sentry's molecules are ahead of the current timeline, this states that he simultaneously exists in the future, present and past altogether. His long time foe Cranio stated that Time bends for Sentry, and every situation that happens all works in his favor, sort of Probability manipulation but in his case it's Time.


  • Chemically Enhanced Physiology: The Sentry's superhuman powers and abilities derive from Golden Sentry Serum. The experimental serum granted him photokinetic based powers, essentially being fueled by the sun itself. His various powers seem to be based in molecule manipulation or reality warping, all stemming from his base solar charged body. Though most of his powers and their limits are still unknown, the Sentry has been said to have the power of a million exploding suns. He is so powerful that Karla Sofen theorized in front of Norman Osborn that what happened after Scarlet Witch broke down would be nothing compared to what Sentry could do. Sentry has also fought Galactus. He was stated to be an Omega-Level Threat by Mister Fantastic, and Nick Fury's intel classified him as Power Level 10+. During a meeting with Professor X, Emma Frost openly stated that the Sentry's powers are godlike, and during his time as a member of the Dark Avengers, Sentry's profile note that there is no limit to his powers and that he is nigh-omnipotent, thus making him the strongest member in the Dark Avengers Team. Following his return latter on, the Sentry finally accept his dark self, the Void and merge with the entity, creating a being far more powerful than all his past incarnations, when considering all the impressive feat throughout the Sentry and the Void lifetime of struggle, the all-new merged Sentry can be said to be arguably the most powerful superhuman on Earth.
    • Alpha Human Physiology (to Superhumans [Mutants / Mutates / Metahumans] only; Variation of Alpha Physiology) / Transcendent Mortal Physiology / Transcendent Superior Human Physiology
      • Molecular Manipulation: Following a confrontation with Molecule Man, Robert discovered he has the powers of molecular manipulation which he had used to revert himself from the liquid Molecule Man had turned him into. The extent of these powers are not yet known, but he was able to defeat the Molecule Man. However it should be noted that unlike Molecule Man, Sentry has little control of his powers. Since The Void and the Sentry are essentially the same person with differing personalities, The Void's own shapeshifting might be a result of the Sentry's molecular manipulation. Additionally Reynold's molecular manipulation ability theoretically would give him potential regenerative healing abilities as well despite his nigh-invulnerability. It has been theorized that the vast majority of his powers are derived from his ability to alter matter and energy and that he could simulate almost any superpower with enough practice and control. He seems to do this unconsciously as the Void when he changes shape and power sets. It is also possible that he had survived from being disintegrated by Morgan Le Fay due to the same power. Since losing his agoraphobia, and therefore gaining full control over his powers (in Uncanny Avengers), he has been able to utilize his power to manipulate molecules to even greater degrees than ever before.
      • Immortality: The Sentry is chemically mixed with the super soldier serum. This makes him and the Void both immune to aging.
      • Superhuman Condition
        • Supernatural Body
          • Superhuman Strength: The Sentry's strength varies greatly and depends on his mental stability. The Sentry possesses vastly enhanced superhuman strength, granting him the ability to lift (press) far in excess of 100 tons easily. He is one of the strongest beings in the Universe. He has demonstrated several astonishing feats of strength during his career, including easily lifting tremendous weights, ripping Carnage in two, taking Terrax the Tamer's cosmic axe and shattering it with his bare hands, moving a cruise liner effortlessly, and his unrestrained power overloaded the Absorbing Man. The Void was even able to break the Hulk's limbs with relative ease, and the Sentry himself was able to easily kill Ares by ripping him in half. He can also absorb solar radiation for additional strength. The Sentry has yet to demonstrate an upper-limit to his strength, but he has shown that it can rival the likes of the Hulk, although this depends on his mental state. The Sentry has also shown enough physical strength to be able beat the Void into submission more than once with pure force when he was relatively stable, which shows a high degree of power. During his most recent battle with the Void inside of the Sentry World, Sentry demonstrate devastating feat in shattering the entire moon to reveal the Void's whereabouts and then kill him easily by ripping him apart afterward. Following his fusion with the Void that granted him access to the combined might of both beings, Sentry has demonstrated an even greater degree of super strength, managing to easily overpower Scout, who had injected himself with the Golden Sentry Serum, to the point of effortlessly crushing his fist and breaking his neck. During an encounter with the Avengers, with Thor, Captain Marvel and She-Hulk in their ranks, the merged Sentry manhandle them and knock them all aside with ease. He stops a punch from She-Hulk and threw her into New Jersey, easily sink islands, picks up a giant cruiser ship out of the ocean it was in, punches can create giant craters in the ground (which is large enough to dwarf the size of the Helicarrier), Overpowered Thor, casually lifts a massive plane, & had managed to hold the energy of the Cosmic Cube.
          • Superhuman Speed: The Sentry possesses the ability to think, move, run, and react at superhuman speeds. He has been observed catching bullets and has also been seen moving far in excess of supersonic speeds; his speed on earth is enough to be gauged as fast enough to move at orbital velocity (5 miles a second). It should also be noted that the Sentry has numerously been depicted as able to fly to the sun in a matter of moments (where it takes light over 8 minutes). This shows that his speed during inter-stellar travels is several times in excess of the speed of light. He has recently shown the ability to travel an indistinguishable amount of light years in a very short of time in flight. Sentry's flight was described to be bending space and time through pure speed, and that the speed he was flying at was so fast that it was disorienting Thor. Sentry has even been able to occasionally match Thor's combat speed in battle. (Thor has routinely matched beings with extreme combat speed, such as Gladiator and Silver Surfer). Don't forget that Sentry operates in milliseconds, which is 1 thousandth of a second. He rebuilt a tower in lightspeed, dodged strikes from Thor's Mjolnir, stopped a bullet from Skrull Sniper Rifle with ease before it hit Norman Osborn, disabled a bunch of nukes before it hit their target, casually dodge/block blasts from Terrax, fly across the entire city in a matter of seconds, & disoriented Thor with his speed.
          • Superhuman Stamina: Sentry's enhanced musculature is far more efficient than that of a human. As a result his muscles produce no fatigue toxins. However, his stamina, along with the rest of his powers, greatly varies depending on his mental and emotional state.
          • Superhuman Agility: Sentry's natural balance, agility, and body coordination are enhanced to levels that are far beyond the natural physical limits of even the finest human athlete.
          • Superhuman Reflexes: The Sentry can react at superhuman speeds exceeding the equivalent of several times the speed of Sound. As such, Sentry was able to catch a sniper bullet from a highly advanced Skrull gun. Sentry has in the past saved Cornelius Worth from a point blank gunshot wound to head from being inflicted on him by the Void. With him taunting Sentry, asking if he was "faster than a speeding bullet". Upon Sentry saving Dr. Cornelius he says to the Void that he himself knew he could catch the bullet because the Void knew how fast the Sentry was to the nearest millisecond.
          • Superhuman Senses: The Sentry possesses vastly enhanced senses. He is able to hear almost any sound at any decibel, pitch, and frequency. The only Earth creature who can detect sounds at the frequencies he can is a blue whale (0.01-200,000 Hz). He has shown enough control to block out ambient sounds to focus on a specific source/frequency (He has remarked that he was able to hear a butterfly's heartbeat in Africa). The range of his eyesight is also far greater than that of a human being. He is able to detect a single person from hundreds of miles in the air and above cloud level. The full extent of Robert's other senses superhuman capabilities is unknown.
          • Superhuman Durability
          • Superhuman Endurance
        • Godly Physique: As a superhero, Sentry possesses god-like physique. He is extremely strong, very fast and very tough. He can rip Carnage apart with his barehands with relative ease, stops She-Hulks punches which are strong enough to send people to another continent and throws her to New Jersery from New York, can travel at interstellar speeds and travel faster than light, catch point-blank bullets without any effort and barely fazed from a nuclear blast. He also has shown to have extreme stamina as his muscles has shown to not produce fatigue toxins and never get tired.
      • Nigh-Invulnerability / Complete Invulnerability: The Sentry is, for all intents and purposes, almost completely impervious to harm, unless he wills himself to be killed he has shown no direct weakness. He has been seen surviving extremely harsh atmospheric conditions, including the vacuums of space. Nick Fury has stated that so far S.H.I.E.L.D. has yet to find a way to kill him, and even Iron Man's scanners found no physiological defects in the Sentry's body. Like all of his abilities, his durability depends on his mental state. He can go to completely no-selling Class 100-level characters but as soon as he wishes himself dead he could be killed in an instant, notably in Siege where he asked Thor to kill him. He has also been damaged when he requested to Hulk to punch him in during the Green Goliath's takeover of Manhattan to prevent himself from destroying everyone on the Earth. Acid strong enough to melt through steel is like shower water to Sentry. Lightning bolts from Ultron that were torturing Ares had little to no effect on Sentry.
      • Flight: The Sentry possesses the ability to float by defying gravity, using his superhuman speed to fly far above hypersonic speeds (above mach 10). He has demonstrated travelling to the Sun and back in a matter of moments which would require him to fly at speeds faster than light. And during the Skrulls secret invasion he flew to Saturn (about 746 million miles distance) almost immediately, which required him either to move at many times the speed of light (still thought to be impossible in this space-time) or to have bypassed space altogether thus giving the impression that he had moved faster than light-speed. He has also been stated to travel at many times the speed of light. One plausible explanation is that Sentry uses his absolute control of his molecular structure to mitigate and or prevent his body from obtaining additional mass as he moves/flies at speeds far greater that light-speed, although this has yet to have been proven or shown. And has also been remarked to fly at such speeds not even a god of Asgard could withstand. Sentry has also been able to fly with such force to behead and kill Attuma.
        • High-Speed Flight: Travel at a speed exceeding speed of light. Sentry can fly at from hypersonic speeds to flying faster than light-speed.
        • Levitation
      • Teleportation: On at least one occasion, Sentry has shown an ability to teleport in a blinding flash of golden light. Sentry teleported away, after meeting Nate Grey, he was also able to teleport from the Sun back to the Earth, and managed to get into an area which was protected by Reed Richard's force fields.
      • Photokinesis: It may be theorized that the Sentry also has the superhuman ability to generate, control, and emit light. This ability to produce hard-light constructs may be similar to those of Dazzler when it was revealed that the Void is a just an expression of his repressed persona, and thus his creation, he has also used it to block an energy blast from Terrax.
        • Light Projection: Having absolute control over the light he produces, he can control its direction, frequency (color), amplitude (intensity), and duration. The Sentry can produce numerous effects with the light he manipulates. He can simply cause a bright glow all about his body, eyes & hands. He can create a pulse of light on the order of several tens of thousands lumens of power per second (the sun produces at most 10,000 lumens of brightness at noontime), which temporarily blinds people with its brilliance. This ability has been proven to be able to calm down the Hulk though it also reduces him to a childlike mentality who believes the Sentry and his wife to be his mother and father.
        • Invisibility: Sentry can turn invisible by deflecting light and radiant emissions.
        • Energy Blasts: The Sentry can generate light, heat, kinetic force, and other forms of energy as powerful blasts and explosions of a yellow color. These blasts are usually generated from the hands and eyes. But he was always like to use its in the form of optic blast. The maximum power of these blasts is unknown. It has shown previously to be capable of burning Hulk's skin and levelling whole city blocks in the past. He has also shown the ability to emit omnidirectional blasts that were able to eliminate a large group of Attuma's soldiers. He also killed Nova during final Scourge event, blast a group of thunder guard for assaulting Asgard and destroy iron man Hulkbuster armor with a yellow heat beam from eyes.

        • Light Amplification
        • Hard Light Constructs
      • Energy manipulation
      • Darkness Manipulation: After merging with the Void, Sentry gained the Void's darkness manipulation abilities. He could generate tentacles from his darkness that could restrain someone as well as knock them away.
      • Psionic Abilities: The Sentry possesses powerful psychic and mental powers mainly used for holding his physical form together, & hold his physical powers within (though it is not yet known whether the Sentry can use them the way Professor X and other psychics use theirs). The few psychic abilities he has displayed so far was implanting his memories inside Paul Jenkins' mind, being able to erase himself from the memories of every being on the planet, with the help of CLOC, Dr. Strange, and Reed Richards. When at his full potential he could even use it in almost psychokinetic ways such as stopping a full-speed Mjolnir throw directed at him by Thor, though this may have been an extension of his matter manipulating abilities.
        • Omni-Psionics
        • Empathy/emotion manipulation
        • Mental projection
        • Cosmic Psionics
        • Telepathic Powers: One of his more powerful abilities, Sentry possesses the ability to invade other people's mind and mentally attack them. He can telepathically communicate with people and break free from illusions. Because of it, he is able to defeat Super Adaptoid with this ability. It's also been stated that Sentry can remove events from history books.
        • Incredible Mental Resistance: Sentry's mind is extremely strong, that not even mental influences or any mind invasion can enter it. It takes the combined efforts of Professer X and Emma Frost to enter his mind and only then they only have access to the white room in his mind. He is apparently immune to Rogue's power.
      • Biokinesis: The Sentry has an unknown or rarely used ability to affect biophysical effects to an unknown but seemingly limitless degree. Both his Sentry and Void persona's having used this aspect of their shared ability for various purposes. Robert once using his power to cure his therapist's daughter of a vegetative state and spinal problems seemingly just by being in the same room as her, while the Void bestowed an young unwed mother with an incurable breast cancer disease from states away.
        • Resurrection: The Sentry appears to be able to bring the dead back to life under extreme emotional distress. After Ultron murdered his wife, Sentry was able to resurrect her by simply touching her. It does not appear he has control over this power, as he was shocked by his ability to do such an act. This may also extend to simply healing others' injuries.
        • Incredible Regenerative Healing Factor: The Sentry can heal himself from virtually all injuries. He twice even came back from having his molecularity dispersed, during his fights with the Molecule Man and Morgan le Fay.
        • Bio-Reality Manipulation
        • Healing
          • Healing Touch
      • Power Sharing: A couple of times the Sentry has utilized a unique ability to bestow portions of his own power onto others or using it to augment existing powers in those of his friends. Taking a young boy named Billy Turner and giving him similar abilities compared to his own and taking him on as a sidekick called Scout, or making a playmate for himself and the Hulk when similarly empowering a dog named Normie who took the name of Watchdog. Reynolds even gave Hulk some of his own quintessence as a means to protect him from his dark half, The Void.
        • Power bestowal
      • Energy Absorption: The Sentry has been stated to be capable of drawing energy from 'anywhere and everywhere' including the Microverse.

  • Genius/Superhuman Intelligence: Robert is very intelligent. He is capable of using his powers to detect all substances in a single object and thence determine how much of what substances make up an object. He is adept with mechanics, architecture, machinery, tracing energy sources, cybernetics, robotics and computer science. He used his great intelligence to construct his Watchtower as well as everything inside of it. Since he has never been very wealthy, it is likely he recovered all of the substances required for his Watchtower's construction from many different areas of the Earth or (perhaps) other planets as well. Once he collected the right amounts of the different substances he needed, he would then forge them into the materials and technology he needed. His other inventions include CLOC (with the help of Reed Richards) and the Watchtower. His intellect allows him to determine all substances in a single object and able to detect what they are. He has shown great skills in architecture, machinery, computer science, mechanics and the list goes on. He invented a device that erased the entire world's memories of him, including himself.

Physical Strength[]

Class 100+; the Sentry possesses superhuman strength enabling him to lift well over 100 tons easily. He has been able to stalemate one of the most powerful incarnations of the Hulk while weakened by his Agoraphobia, destroy the shields of Dr. Doom, and even contain a Cosmic Cube for a while before it was absorbed into the Sentry's body. Marvel dubbed The Sentry as the world's most powerful superhero at some point in time. He is still able to harm Absorbing Man, despite him being amped by the Cosmic Cube.


Due to his condition, Robert suffers from many weaknesses:

  • Psychic Assault: The Sentry has a fragile psyche and is readily susceptible to mental manipulation. Although if he is relatively stable he can resist such manipulation, as he has in the past when Dr. Strange tried to convince him that the Sentry wasn't real and that it was an illusion, stating that "he was always too powerful for this type of magic".
  • The Negative Zone: The Sentry is at his weakest in the Negative Zone, which is Blue Marvel's source of his strength & power. His powers and health gradually deteriorate the longer he is inside the zone itself and even worse, his counterpart/nemesis The Void's powers increase to maximum. However, in his new state while merged with the Void, Sentry was able to retain all his superpowers in the Negative Zone without weakening at all.
  • Lack of Control: Sentry doesn't seem to have complete control over all of his abilities, as he didn't even know he was capable of Molecular Control until his battle with the Molecule Man and was genuinely shocked after reviving his wife from the dead.
  • Vulnerability to Chi: Spiritual energy based attacks, such as Chi, have been shown to be capable of injuring Sentry especially when inflicted by someone powerful.
  • A multiple personality disorder which results in the creation a villain known as The Void that sometimes takes over him.
  • Former Weaknesses
    • Mental Illness: The Sentry's mental instability has led to his immobility on several occasions. He suffers from one if not several mental illnesses real and fictional. The Agoraphobia makes Sentry fear releasing his full power as he stated if he lost control even for a millisecond, there would be dangerous consequences. Characters have taken advantage of Roberts' Agoraphobia in battle, one occasion Jimmy Hammond made Robert believe that by heating him up he would release the Sentry's full power. As Robert is an Agoraphobic, this lead him to fly away to escape. Since then he has lost his Agoraphobia since returning as a Horseman of Death.
      • Even before becoming Sentry, he suffered from agoraphobia and anxiety disorder.
      • He was diagnosed as agoraphobic, paranoid schizophrenic, suffering from GAD (Generalized Anxiety Disorder) and from a premorbid schizotypal personality disorder.
      • He was stated to suffer of Agoraphobia and Schizophrenia, among others.
    • Even when he's not dealing with the problems of the Void, Sentry still has a very high degree of instability. He's VERY open to manipulation (either psychic manipulation or anyone who is able to mess with his mind & play head games). The Sentry is prone to bouts of depression, prone to bouts of low confidence in himself which can sometimes paralyze him with fear, even though he's one of the most powerful beings in the entire Marvel Universe. But when his confidence levels are high, he's virtually indestructible.




  • Sentry's Watchtower


Allegedly due to covering up his past as a thief and addict,[31] Robert Reynolds projects an entity as a dark side effect of his powers.[55] It has been claimed that for every benevolent act the Sentry performs, the Void corresponds with attempting an act of malevolence. He was formerly unaware that the Void was a false personality, but has since been informed otherwise. In the 2009 storyline "Utopia", it was temporarily separated from his being, with a "shard" of its essence placed within Emma Frost which is later transferred to Scott Summers and currently resides locked away in his mind.[56]

Several reasons for the existence of the Void have been given: the innate division between good and evil in any nominally normal person; a "mind virus" put into place by the mutant Mastermind by order of the crazed General;[55] the idea that the Void is in fact the true personality of Rob Reynolds, and the Sentry is the false one;[57] as mentioned above, the result of covering up his past;[31] and, according to Norman Osborn the Sentry's superhumanity eroded his humanity, leading to a 'void' in his life. During the Siege story line, the Void exhibits a more demonic form, capable of nearly slaughtering Thor, bringing down the entire city of Asgard, and striking down every immortal and mortal hero set against it simultaneously, as well later destroying the Norn Stone-powered Loki in seconds. Norman Osborn claims that it is the Angel of Death,[35] tying into an earlier prelude which showed the Void's presence in biblical times.[volume & issue needed] As yet, it is not clear which, if any, of these reasons is in fact the real one.

The Void possesses the ability to shape-shift, and through its control over the weather and darkness it can create destructive storms and deadly "infini-tendrils" that attack the mind. Victims impaled on the tendrils experience traumatic visions of the past, present, and future. Its regular appearance varies between a shadowy, trench coat-wearing villain to a massive hurricane of darkness. It can also assume powers dependent on shape, like a flame form that breathes fire, alternately an armored monster with super strength and toughness. It is at its strongest during the night and in the Negative Zone, where it has shown itself capable of easily overpowering the Hulk by breaking almost every single bone in his body in moments.[volume & issue needed] Coincidentally, Sentry is at his weakest in the Negative Zone. A mere physical assault required much effort to hold off, even with the combined force fields of Iron Man, Doctor Strange, and the Invisible Woman, while the united forces of the New Avengers, Fantastic Four, X-Men, Inhumans, Illuminati, and heavily armed S.H.I.E.L.D. agents simultaneously attacked it.[58]


The Void - both as a part of the Sentry and a separate entity - possesses the following abilities:

  • Superpowered Physiology
    • Aspect Avatar Physiology
    • Molecular Manipulation: The Void possesses similar matter and energy manipulation abilities as the Sentry. Having used it to entrap the Avengers within an inescapable shroud of black matter he had conjured up, material easily able to hold the likes of Thor and Giant-Man with ease. At its most focused i.e. through his tendrils, the Void can cause total atomic cancellation within a target, as he did when he disintegrated the immortal Loki.
    • Immortality: For all intents and purposes, the Void cannot and will not ever truly die even long after being hurled into the sun both by Robert and later killed by a bolt of lightning by Thor. That the dark aspect of the Sentry cannot expire in any sense, coming to be an existing entity all its own; it even left the chronically dying and regenerating body of its host while trapped in the sun.
    • Superhuman Strength: The Void's physical abilities are a direct mirror reflection of his counterpart, though it's reputed that The Sentry is visibly stronger. Despite that Void has enough physical power to easily man handle gods/deities and monsters with little effort on his part, be it shattering the all but unbreakable bones of the Incredible Hulk or even knocking around the Sentry through a host of carnival rides with relative ease. He was even able to pry open an interdimensional portal linking the Posiverse and the Negative Zone with his bare hands.
    • Warping Speed: Void also boasts the ability to think, move, run, and react at beyond superhuman speeds. As a thought effigy born of living shadow, he may actually be faster than his good side. The Dark Sentry can appear anywhere at any given time across the world and beyond with or without the Sentry knowing it, capable of moving and traveling thousands to trillions of miles at the drop of a hat before returning to his creators shattered psyche.
    • Superhuman Stamina: Dark Sentry has an advanced musculature greater than that of any human and most known superhumans. Being a being of thought, his muscles produce no fatigue toxins, affording him all but unlimited physical stamina.
    • Superhuman Agility: Void's natural balance, agility, and body coordination are enhanced to levels that are far beyond the natural physical limits of even the finest human athlete.
    • Superhuman Reflexes: The Void can act and react at above superhuman speeds exceeding the equivalent of several times the speed of sound. As such, he/it is quick enough to match the highly adept Sentry in the art of superpowered fisticuffs with little difficulty. Void is easily quick witted enough to counterattack Ares as he pounced on him from behind and is capable of battling whole scores of Marvel's superhuman community with ease and without so much as a wasted movement.
    • Superhuman Senses: It, like the Sentry, is able to hear almost any sound at any decibel, pitch, and frequency. The only Earth creature who can detect sounds at the frequencies he can is a blue whale (0.01-200,000 Hz). He has shown enough control to block out ambient sounds to focus on a specific source/frequency (He has demonstrated hearing a butterfly's heartbeat in Africa). The range of his eyesight is also far greater than that of a human being. He is able to detect a single person from hundreds of miles in the air and above cloud level. The full extent of Void's other senses superhuman capabilities is unknown.
      • Sensory Scrying: The Void's senses are tied to those of the Sentry's senses. Everything Reynolds sees and does, it will know instantly.
      • Clairvoyance: On its own, the Void also possesses extra sensory perception of unknown potency. Being more attuned with the world around him than just of the tangible spectrum, such as sensing if and when his human self has been disturbed by the presence of another force or ascertaining what Loki had done to empower the heroes standing against him.
    • Psionics: The Void possesses telepathic, empathetic and possibly cyberpathic capabilities. The level of which being unknown but quite possibly rivaling that of the Sentry himself. Having once used such a facult of his powers to taunt his heroic self through a television screen. Showcasing some mildly impressive remote technological operation.
    • Flight: The Void also has the natural ability of aviation, used in conjunction with his superhuman speed to fly far above hyper sonic to trans-light speeds. He can match Sentry in a contest of flight speed as well as sit stationary in mid-air if need be. He can even fly at speeds high enough to outpace even a god of Asgard, battering him into near unconsciousness in a single stroke.
    • Photokinesis: While a dark element, The Void in tandem with the Sentry often emitted light within darkness.
    • Atmokinesis: The Void has massive control over the weather and can create destructive storms.
    • Adaptive Appearance: The Void is a highly adept shapeshifter, constantly changing and alternating his appearance on the fly. With varying forms ranging from a shadowy, trench coat-wearing villain to a shell skinned mega beast, monstrous flame effigy, an obese pustule atrocity, or massive hurricane of darkness. He can even turn into a copy of the Sentry.
    • Adaptive Possession: The Void is capable of hosting most any individual he desires and endowing them with his powers, as he did with Dr. Strange during his battle with Loki over his title of Sorcerer Supreme.
    • Infini-Tendrils: The Void can create deadly infini-tendrils. Those impaled on these tendrils experience traumatic visions of the past, present, and future. The Tendrils are also capable of causing physical damage, for example when they broke every bone in the body of the Hulk.
    • Umbrakinesis: The Void has massive control over darkness.
    • Ultimate Intangibility: Sentry's dark personality can physically change and alternate molecular/atomic density and cohesion in order to phase through objects and people while inflicting tremendous pain on a subject.
    • Night Augmentation: The Void is at his strongest during the night.
    • Negative Zone Augmentation: The Void's powers increase to maximum whenever he is inside the Negative Zone.
    • Biokinesis: Like its counterpart the Sentry, the Void has an as of yet untapped capacity to affect organic matter in undisclosed but seemingly unlimited ways. The Void persona uses such attributes to malignant ends, while his lighter half acclimates more beneficial ones. Its power over such aspects is so great that the Void afflicted a women with breast cancer a world away.
    • Inner Beast Power Link
    • Dark Form
    • Jungian Archetype Mimicry
    • Tentacle Manifestation
    • Madness Form
    • Death Touch
    • Nothingness Attacks



  • Magic: The Void can be sealed with powerful magic, as was done by Doctor Strange.
  • Chi: The Void was proven to be vulnerable to spiritual energy attacks like Chi.
  • Domination of darkness: The Void being technically a dark entity, any deity with control over other beings of darkness can bend his will.
  • The Sentry can overpower & defeat the Void, both physically/materially, mentally/psychologically & spiritually/strongly.


Joining Sentry to take on the Void are his sidekick, Scout, his loyal canine companion Watchdog and his equal, Sentress.


Better known as Scout, Billy Turner is the sidekick and partner of the Sentry. After the Sentry made the entire world forget of his existence with the help of Mister Fantastic and Doctor Strange in order to stop the Void, Billy went on to live a normal life. He lived with his mother and worked at a fast food restaurant. When the Sentry first re-emerged, Billy's memories of his life as Scout returned. He suited up on his old costume and joined the Sentry and numerous other heroes at the Statue of Liberty to take a stand against the Void. When the Sentry saw himself forced to return to obscurity, Billy returned again to his normal life.[55]

Scout's powers are similar to Sentry (superhuman strength, speed and stamina, regenerative healing, flight etc.), and were also obtained by drinking the super serum.


Watchdog is a super-powered Welsh Corgi. He takes verbal orders from the Sentry. The orders are given by the prefix Watchdog, directly followed by commands, such as, Guard, Stay etc. Watchdog always obeys.[56]

Other versions[]

Age of Apocalypse[]

A zombie Sentry appears as a member of the Black Legion in the "Age of Apocalypse" reality.[57]

House of M[]

After Wanda Maximoff changes the world in House of M #1, Robert Reynolds is seen briefly with Doctor Strange in a therapy session. He tells Strange about a dream in which he sees an immense darkness (the Void) coming down on him.[58]

Marvel Zombies[]

A version of the Sentry is responsible for the zombie outbreak depicted in Ultimate Fantastic Four and Marvel Zombies. A costumed hero resembling the Sentry appears from another universe, looking for food. The Avengers attempt to intercept him, and are immediately infected. The zombie virus rapidly spreads to nearly every super-powered character in that world. The costumed hero responsible for the outbreak is never called by name, and is only distinguishable by his outfit. What happens to him after his initial contact with this universe is unknown.[59]

In Marvel Zombies vs. The Army of Darkness, it is revealed that the zombie Sentry was undead in the afterlife, eating everyone that came into the "light" and knocking Ash into the not yet infected world of superheroes. Unfortunately, the Sentry finds its way through the same portal and infects the Avengers who came to tackle him in the first place.[60]

In Marvel Zombies Return, it is revealed that the Sentry's infection and universal travel is a predestination paradox. When the Giant-Man of the Marvel Zombies universe comes to a past version of the Marvel Universe, he infects the Hulk, who then infects the Sentry. At the conclusion of the story, Sentry is sent through the multiverse by that Earth's version of Uatu the Watcher and infects the Avengers, setting off the entire series of events while 'containing' the infection between these two universes so that it will essentially 'devour itself'.[61] In the one-shot Marvel Zombies: Evil Evolution, Zombie Reed Richards speculates that a dimensional teleporter he was testing may have pulled the Sentry from his reality, though whether this was from the Gates of Heaven or was the other end of Uatu's teleporter is not revealed.[62]

Age of Sentry[]

This version of Sentry is mostly identical to the mainstream counterpart, becoming a hero and battling villains alongside Scout, Watchdog and the Sentress and falling in love with Lindy Lee. Afterwards, the villainous brain-like alien Gorax was able to take away the powers off Sentry, resulting in Robert and Lindy going back in time and regaining his powers. Then, the two villains known as Phineas Mason and the Mad Thinker started posing as two film-makers who were using their machinery to drain Sentry's power which ultimately failed.[63]

Deadpool: Killustrated[]

In Deadpool: Killustrated, the corpse of a Sentry is seen along with other deceased heroes after being killed by Dreadpool.[64]

What If?[]

The Sentry has appeared in some issues of What If:

  • In What If the Skrulls succeeded in their Secret Invasion?, Sentry is allied with the Skrulls, along with the Thunderbolts, and fights the Avengers Alliance For Freedom when the Skrulls invade Wakanda after Marvel Boy destroys a Conversion Temple with a suicide attack. During the battle against the Avengers Alliance, Sentry destroys the vaccine cannon built for spreading a modified Legacy virus around the planet, which was meant to reverse human conversion into Skrulls. After the destruction of the cannon, Sentry continues fighting Thor, who gains the upper hand and regretfully declares Sentry too dangerous to let live. Thor kills Sentry by snapping his neck.[65]
  • In What If Osborn Won Siege?, Sentry kills Ares prior to the assault on Asgard and as a result is able to focus on the other heroes present. Sentry kills most of the heroes, allowing the Dark Avengers to murder the rest. Afterwards, a cabal led by Dr. Doom confronts Sentry with the knowledge that Bullseye killed his wife Lindy in the hopes that Sentry will turn on Osborn. However, it sends Sentry over the edge and he allows the Void to take complete control. As the Void, he kills the Cabal, Bullseye, Osborn and eventually destroys the Earth, with foreshadowing that he would begin moving through the universe wreaking destruction.[66]
