Jackalope

About: 

Jackalope is the total hyped freak that always sus people with no apparent reason, jumping on the spaceship and making friends anywhere for his dynamic and stupid persona. Since he was contaminated by an parasitic alien virus he can change himself and use the strange abilities to his advantage. He can disfigure his face as well when he's the impostor: your homie creepy smile full of sharp teeth, distorted body and multiple arms and legs; can make his face more monsterous, or just change his ears since he's a huge fan of it.

Jackalope can be described as the most most creepy individual when he's the impostor, leaving traumas [•••]  around the spaceship when he kills, using vents to move around. Loves to kill in security and when lights are off 

Random curiosities: 

•has an Hysterical Laugh that everyone rather laugh than worrying about, laughs harder when someone accuses him randomly, making their self esteem really low 

•his little crewmate's name is Pif, he's actually a robot- 

•loves to use his tail to grab things and people with it, especially the poor Charlie that always harass

•Is the one that survives most of the time, people don't usually kill him till the end, probably for being such a passive aggressive person during emergency meetings
