In the various Sonic the Hedgehog continuities, there are several instances where the characters encounter extraterrestrial life.
Games[]
Sonic X[]
Seedrians[]
Metarex[]
Dark Oak, leader of the Metarex.
The Metarex are an alien race of bio-robots. The five most powerful and high ranking Metarex, Dark Oak and his commanders, are actually the only suriving male Seedrians. Two of the Yellow Zelcova and Red Pine. Desiring the power to unlock transformations that would enable them to defeat their enemies, they stole energy from their home world's Planet Egg and were transformed. From that point on, the Metarex sought to achieve domination by destroying all animal life in the universe, allowing plants to rule over all.
Marmolimians[]
The Marmolimians are aliens that hail from the Planet Marmolim. They resemble short creatures with heads that are either round, shaped like a Chao's head or stretched. They also have small tufts of hair on their heads. The Marmolimians are apparently religious, frequently using magic-based charms in love and fortune-telling. Their only appearance was in the 69th episode of Sonic X, where they helped the relationship between Tails and Cosmo somewhat. Marmolimians possess ships that resemble meteors. They also use a coin-based currency called Fleebos. Four Marmolimians named Lu, Leela, Momo and Gana (the latter is the spiritual elder) formed the crew of the ship that they owned.
