A kind yet sensitive male Impostor. He became an Impostor after taking half of Purple's stone-like sabotage device. He was allied with Fortegreen, but the alliance broke after he fled from Forte's constant gaslighting. He is the third strongest. Best friends with White and Blue. Suffers from insomnia. Cherishes Glitch like a son. Kind to friends but harsh toward other Impostors. Occasionally sees ghost hallucinations when under extreme stress.

A cold and blunt male Impostor. After Red took half of his stone-like sabotage device, he began pursuing him obsessively to get it back (he also became an Impostor through that machine in the past). He is the strongest. Allied with Pink. Rarely speaks or just watches if talking is unnecessary. Values logic over emotion. Usually shows very little facial expression. Trusts very few people. The only one who can see ghosts (and talk to them). He's so used to it now that he doesn't pay them much mind.

A sly and rude male Impostor. He was allied with Red, but Red eventually ran away due to his constant harassment, breaking the alliance (he still harasses Red). As a shapeshifter, he can change his body color at will when needed. Has four tentacles on his back. Knows Red's weaknesses better than anyone. He is the second strongest, after Purple.

Wait, I just realized that pink tentacle had three parts... A cheerful and bright female Impostor. She loves—no, adores—pizza and ice cream. You can get her to do anything if you persuade her with talk of pizza. Has three snake-like tentacles on her back. She doesn't go out of her way to fight, but she is incredibly agile when she does. Allied with Purple. Very gluttonous and has teeth like steel (wait, does she even have teeth?). Somehow ended up becoming close with Blue.

An immature and cowardly male crewmate. He wears bandages around his head and body due to a major injury in the past. He has his own kickboard and tablet and loves gaming. He lacks situational awareness, so he's always being dragged around by White. Best friends with Red and White. Fairly close with Pink, but naturally, he's terrified of her. Though he's a coward, he truly treasures his friends.

A calm and quick-witted female crewmate. A master of social dynamics with the highest situational awareness. She always prioritizes Blue and looks after him. She hates Fortegreen but fights with Purple even more. Close with Brown. Best friends with Red and Blue. Her job is a Communicator. She and Brown were like siblings. She has a warm side to her.

A pure and kind male crewmate. A son-like figure created by Yellow. He follows Red like a biological father and relies on him heavily. Skilled with machinery, he often fixes broken equipment. Though fearful, he finds courage for the sake of those he loves. Close with Red, Blue, and White. He is only 7 years old, so he is very curious.

"Haha... it's not over yet." A playful and optimistic male crewmate (Ghost). After his death, he appears only to Purple. His characteristic playfulness remains even in death. He occasionally teases Purple or drops hints. He considered himself Purple's best friend when he was alive.

"It's okay. You survive." A kind and responsible female crewmate (Ghost). Sacrificed by a vote on Polus. She deeply cherished her son, Glitch. After her death, she appears only to Purple. She quietly offers advice in moments of crisis. (Ugh, her story is the saddest T_T)

"...This time, make sure you live." A quiet and composed female crewmate (Ghost). Died while attempting to escape during the war on Polus. She was a doctor in the Polus medbay when she was alive. After her death, she appears only to Purple. She is a woman of few words but provides strength when it's needed most.
