Indigo

Indigo is ultimately antagonistic towards every Crewmate they see because they believe they are all a danger to the lives of the Impostors that they intend to protect despite being a former Crewmate, and would not hesitate to kill them if necessary. Their main goal is to protect their fellow Impostors that hides in the Impostor Hideout, which is a location that they are the leader of. They have shown huge hatred towards the Mira HQ Scientists, especially Dr. White, for experimenting on the Impostors, as well as disliking the Rescue Team since they work with the Mira HQ Scientists. But they are grateful to those who manages to do something successfully that benefits them, such as when Indigo gives Green a thumbs up when they manage to vote out all the other Crewmates. While Indigo has good intentions of shielding their fellow Impostors from what they perceive as a threat (like the Crewmates), they are very dangerously easy to anger. Their anger issues often clouds their judgment and causes them to be proned to impulsive and reckless behavior, sometimes killing other Impostors either intentionally or unintentionally. They also believe they know what is best for all of them and is not afraid to speak up their mind, but would not mind letting the others pick and decide if they think it is necessary. After coming back from their expedition above, they have given Dark Slate Blue meat despite the fact that they are now old and lack any teeth at all, which could indicate that Indigo is rather insensitive to their own parent's condition. But regardless, they have shown to at least have some degree of respect for the elder Impostor since they followed Dark Slate Blue's commands at one point.
