Impostor

An Impostor is a parasitic alien organism capable of shapeshifting. They are best known for imposing as Crewmates and slowly killing them off. Their home planet or native solar system is unknown.

General Information
The Impostors are only known by MIRA and Super. How they got onto MIRA ships, such as The Skeld and the Dropship, is unknown. They have only been seen imposing as Crewmates, and have never been seen in their normal forms or imposing as any other astronauts. Their species is also unknown to all, considering they just spontaneously appeared out of nowhere relative to those working at MIRA.

The exact number of Impostors is also unknown, as every time they get eliminated or ejected, more seem to pop up, so the exact amount is unquantifiable.

Connection to Other Species
The Impostors are evolved versions of the Martian alien known as Calvin.

Trivia

 * The Impostors are based off of the video game Among Us, released by InnerSloth on June 15, 2018. In the game, Impostor is one of the two randomly selected roles, the other being Crewmate. As an Impostor, your goal is to kill off the Crew and sabotage the ship. If your goal is met, you earn an Impostor Victory.
 * As Impostors are generally a mysterious species in the RPverse, that also correlates to their mysteriousness in Among Us. Just like the RPverse, the exact number of Impostors is unknown, but in the game, 1 to 3 are normally chosen.
