A solemn and cruel male Impostor. The most widely known leader in MIRA HQ. Purple's father and DSB's son. When he first saw Green, he mistook him for an Impostor. He is the only Impostor with a massive build and large, sharp fangs. He is the strongest and most famous. Secretly has a thing for older men(?) He is only slightly kind to his own family. {Backstory} - Indigo was originally a Crewmate at MIRA HQ (Really? I just found this out), but became a Parasitic Impostor due to a parasite outbreak at the base. - He later became the leader of the Impostor hideout, leading other Parasitic Impostors like himself. (Wow, I seriously didn't know this, that's crazy.) {Transformation} - When he transforms, flames mixed with purple and white light burn fiercely from his back, and his eyes turn a cold, glowing white. - He opens his mouth wide, appearing more threatening than usual, clearly revealing his large, sharp fangs. - This form is less a simple physical change and more a manifestation of intense rage and heightened emotions. - However, it isn't completely uncontrollable; DSB is one of the few beings who can calm him down and is almost the only person Indigo actually listens to. In fact, DSB once stopped Indigo when he tried to attack Green.

A cold and blunt male Impostor. He doesn't show much emotion, but his feelings come out strongly when he's angry. Indigo's child and DSB's grandchild. He loves steak and is terrible at drawing. He had a best friend named Lime, but Lime betrayed him. Growing up under Indigo, he is also incredibly strong. {Backstory} - He's not from MIRA HQ; he was a Crewmate on a spaceship called The Skeld. - He became an Impostor because of an Impostor Relic (Sabotage Relic). - He was a colleague of Green's, but disappeared as soon as he became an Impostor.

A gentle and laid-back female Impostor. Her name is too long, so she's called Slate, Dark Blue, or DSB. Indigo's parent and Purple's grandparent. Unlike other Impostors, she does not kill Crewmates. She loves sleeping and has a playful side that enjoys teasing people slightly. She dislikes tense situations. She can manifest black tentacles from her back, but due to her age, they are weak and slow. Because of her age, she can't eat hard things and has no teeth. That's why she doesn't kill Crewmates. {Backstory} - She was also a Crewmate at MIRA HQ. - She was infected by a parasite during the MIRA HQ incident and became a Parasitic Impostor. - She seems to be retired now.

A playful and bright male Impostor. An active troublemaker who acts as he pleases. He is very interested in new items or accessories and takes most situations positively. Because he is still young, he acts egocentrically. He pouts easily if he doesn't get what he wants. He has good intuition and acting skills, enough to manipulate emotions or act slyly depending on the situation.

A calm and intelligent male Crewmate. A scientist and researcher at MIRA HQ. He wears a black fedora and a plague doctor mask to hide his face. Under his white lab coat, he wears a black shirt, dark blue jeans, and black lab gloves. He has a cold and rational personality, valuing research and results over emotions. He has excellent powers of observation and analysis. He is currently conducting research on Glitch and Impostors. He is obsessed with his research to the point of making dangerous choices for the sake of his goals. While he appears calm and logical on the surface, he is a cold individual who will use others for his experiments. He shows suspicious behavior, constantly approaching Glitch to use him as a test subject.
