Four (4) is an Algebralien and the main host of the fourth season of the Battle for Dream Island series, Battle for BFDI/BFB, created by Cary and Micheal Huang. While he is first officially introduced, alongside X as the co-host, (within the Battle for Dream Island series) in Battle for BFDI/BFB as the main host of the show, never appearing in any BFDI season prior to this, he does make his first appearance, alongside X, in the 2008 educational video "X Finds Out His Value". Four also doesn’t tolerate criticism in early BFB, known to act with violence as shown in "Four Goes Too Far".
Especially seen in early BFB, Four exhibits very surreal mannerisms, including being able to mutilate, revive, screech (causing either the stunning or death of the victim), shoot energy beams from his hands (causing the paralyzing and painful shock of the victim) or suck other characters into his body (sending them to the EXIT).
In "B.F.B. = Back From Beginning", Four merged into the Desert. He reformed to his original state in "Chapter Complete."
Four makes a cameo on both TV and in the stinger in "You Know Those Buttons Don't Do Anything, Right?". He reappears and returns in "The Great Goikian Bake-Off" as a chef with X.
As of "Last One Standing", Four is sapped of their powers due to Pencil absorbing them from him. In "Alone", Four was trapped by an overpowered One in the same Moon she broke out of, who kicked it far away into space, as a means of revenge for doing the same thing to her in the past.
In 2018, Four along with X became the Official English language Jacknjellify YouTube channel mascots after a request by some fans.

Before being the host of the fourth season, Four appears as a picture in the second season.
Four and X finally became hosts of the fourth season, Battle for BFDI/BFB. In "Getting Teardrop to Talk". Four is first seen grabbing Black Hole as he slowly begins crushing him in his fist, making him smaller. The objects are confused as to what he is, Liy tries squishing him. Four then mutilates Pin to show off what he can do. Four starts screeching the contestants until Dora says something to him that he understands. Pillow suddenly attacks Four but ends up dying in the process. Bell mourns Pin and Pillow being dead until Four shows that he can recover the dead.
Four then asks if the contestants want to play a game, presenting them with a chance to win A BFDI. Everyone unanimously cheers over the prize, so Four has then split into 8 teams of 8. When they are finished, Four tells them the first contest, which is to get X's baskets back to him. iance loses the contest and Four tells the viewers about the new form of voting with square brackets.
He is then a host of the fourth season in subsquent episodes except for episodes 9 and 10 (where X is a host) and episodes 28, 29 and 30 (where Announcer is a host).
In the fifth season, Battle for Dream Island: The Power of Two, Four and X return two years after the finale of Season 4. In "The Great Goikian Bake-Off", Four and X appear as chefs for the inhabitants of the hotel and throughout the episode, tries to stop the Strongest Team on Earth from getting to the kitchen where the food is located. At the end of the episode, Four and X mutilate and zap the contestants that are trying to reach the kitchen.
In "The Power of Four", Four and X step in to host TPOT while Two mourns Gaty's disappearance. Four suddenly appears in front of Fanny and Ice Cube as they run down the stairs. The impact causes both of them to shatter into pieces. Four casually picks up their remains and sprinkles them onto the cake. The scene then shifts to the Cake at Stake intro, but it's poorly edited. Every scene featuring Two is awkwardly replaced with badly edited photos of Four.
In "BFB 31", Lollipop is about to mail Four a letter about her stolen Yellow Face Silver Standard Gold Credit Card, when Four suddenly appears from the mailbox. Later, in the TV studio, Four demands to know who stole the card. After interrogating Woody and Blocky, he plugs everyone into Bubble's memory. He reveals the challenge: the post-splitters must explore their memories to discover who took the card and where it is now. However, Four mistakenly places everyone into the wrong memories. He calls Loser to explain the mix-up, but adds that they'll still be able to find the card. Later, Four teleports into Lollipop's memory, where he announces that Blocky found the card. Blocky insists this means he gets to keep the card in the real world and demands to be let out. Four warns him that he won't like what happens if anyone other than himself tries to get Blocky out of the simulation, and creates a portal in Taco's memory that will open in 30 minutes.
In "Last One Standing", the events in the hotel from the last episode are shown again. When Fanny kicks down the door with Tennis Ball and Golf Ball, Four turns to them and asks Fanny about the notes on the whiteboard, then tries to decipher them with Four's power, before being interrupted by a lightning strike from the the rift changing a window. Four was confused about it at first, but after seeing Black Hole's struggles with holding the rift back, Four began absorbing Two's power. When he was confronted by Liy, he explained that he tried to remove the rift as well and that Two has the power. When Liy gets upset about it, he transfers some of the power to her and Pen and tells them to hold off the rift. Four then transfers some of it to Fanny as well.
The fifth season also includes the horse variation called Fourse, who made its debut in Bottle for Dream Island.
