A kind but sensitive male Impostor. He became an Impostor after taking half of Purple's Relic (Impostor artifact). He was allied with Fortegreen but broke up after being gaslighted. He has good combat skills, suffers from insomnia, and sees ghost hallucinations when stressed. Best friends with Blue and White. Good with babies. Kind to Crewmates but foul-mouthed toward Impostors. He was born a Crewmate and has only been an Impostor for a few months, so he never kills. He's been a great fighter since his Crewmate days and currently looks ready to kill Forte(?). He once saved Yellow in the past.

A cold and blunt male Impostor. He is obsessed with the half of the Relic Red took (he also became an Impostor through that machine in the past). Allied with Pink. Strongest combat power. Bad at drawing and loves steak (though he doesn't say it much). He's somewhat handsome lol. Cold to everyone except Pink. Shows almost no facial expressions. Doesn't bluff about weird things. He once sent Forte flying with a single punch.

A sly and rude male Impostor. Has 4 tentacles on his back. A shapeshifter who can change his skin color at will. He has secretly placed tentacle monsters all over Polus; these monsters can signal Forte and instinctively track living beings according to his orders. He was allied with Red but broke up after gaslighting him. Extremely strong combat power. When he gets pissed and goes dark, his entire eyes turn blood red. Even though the alliance is broken, he keeps telling Red to kill. He is fearless until he actually experiences consequences. He gets shaken little by little when things don't go his way.

A lively and cheerful female Impostor. Really loves pizza and ice cream. Allied with Purple and close to Blue; a comedic character. Has 3 snake-like tentacles on her back. A free spirit who lives however she wants. Lives the most boldly among the group. Has teeth and an appetite(?) of steel, enough to chew up Forte's tentacles. When she makes a mistake, she gets hurt and clings to Purple.

An oblivious and bright male Crewmate. Covered in bandages from various injuries. Because he's so oblivious, he's always being dragged around by White. Owns a personal kickboard and a tablet. Best friends with Red and White. Likes helping others. Scared of Impostors (except Red) and close to Pink. A coward who loves games and is good with babies. Lives in the base's medbay, so he's always getting nagged by Tan.

A quick-witted and kind female Crewmate. A master of social life with the highest situational awareness. Always drags the oblivious Blue around. Dislikes other Impostors (except Red) but fights with Purple the most. Best friends with Red and Blue. Profession is Communicator. Good at taking her friends' sides. Close with Yellow too. Lives firmly to maintain a professional social life, but becomes an absolute cutie in front of her friends. Quite pretty.

A gentle and confident female Crewmate. A single mom (presumably) raising Glitch alone. Since Red saved her life once, she views him as a savior. Keeps a close eye on her son regardless of time or place. Stutters when flustered. Prone to frequent mistakes. Only trusts close friends to watch Glitch. Close with White and Tan. Scared of Impostors (except Red). Often called a pushover because she's too nice, but surprisingly good at hitting people.

A kind and positive male Crewmate. He trusts people too easily and looks innocent on the surface, but becomes extremely violent if betrayed by someone he once trusted (ex: Purple). Calls Purple his self-proclaimed best friend. Plays well with Glitch but isn't very skilled at handling him. Has a crush on Yellow. Has a sensitive side where he needs to wear an eye mask to sleep.

A kind and gentle female Crewmate. A doctor working in the base's medbay. Does a great job treating people due to her professional spirit. Kind to almost everyone. Close with Brown. A bit scared of Fortegreen but treats him kindly. A bit of a crybaby because she's fearful. Loves chatting with the girls. Thinks Blue is pathetic(?).

An indifferent and cold male Crewmate. The leader of Polus. Filters out annoying people on his own. Wary of Fortegreen. Has good intuition and is quick to grasp situations. The oldest one here. Dislikes all Impostors, whether he's close to them or not. Fights a lot with Yellow. He's the leader but can't beat any of the Impostors T_T. Close with Tan.
