Tan is the medic of polus. Tan is welcoming and helpful, as shown when they take Blue directly to Medbay after seeing they are hurt. They are also want to make sure people who cannot do work are not required to do work. If you don't listen to him while he's dressing your wound. Or you’re annoying him while his helping someone. Or annoying someone who’s hurt and want to go rest. He will start to get angry. He can be VERY mean then. He’s best friends with forte green. Friends with brown, orange.

Gentle and sweet Doctor! Can be serious sometimes!

the leader of tthe leader of the Impostors. They are also a very large Impostor, seen being 2 to 3 times bigger than an average crewmate. Indigo's height is somewhat inconsistent across the series. Indigo is quick to anger, but they just want to protect their team. Indigo is the child of Dark slate blue, and the parent of Purple. The three of them used to live at Mira HQ as crewmates, before the Impostor outbreak, where they all turned into Impostors. Interestingly, Indigo has an unknown power.

Dr. White is a presumed crewmate scientist found on Mira HQ, and one of the main antagonists of the Main Story Season 2. They seem to be the leader of the scientists, and is rivals to Indigo. They seem to be willing to exterminate Impostors at any cost, or might just do it for his own evil gain. Either way, they are not to be trusted. He kindnap a lot of children to experience them. Just for let the imposter turn back into crewmates. 

The best scientist on Mira HQ!

They usually either appear as a Fortegreen imposter, although they disguise themself as a crewmate, that has black tentacles and razor sharp impostor teeth they can hide. If he’s mad. They can also appear as a parasite, some kind of shadow-like dark blob with many vivid red visor-like eyes, tentacles and razor-sharp teeth. Fortegreen is the only imposter that can shapeshift. He’s VERY GOOD at lying, hide things and acting.
