Greater Venting Crewmate
An uncommon species that has been seen on the planet Polus, but has also been known to stow away on airships and hide in space stations and the Amogus Headquarters. Keeps its venting secret. Its main food source is the tears of dead Lesser Task-Doing Crewmates, not to be confused with Lesser Task-Faking Crewmates. It seems to pretend to be one of its food source, and then it seems to kill them when nobody is watching. Its weakness is lava, asphyxiation, G-force, and being found out to be the Imposter. Mating ritual: killing its mate before they can have children. Very inefficient.
I'm totally not a Greater Venting Crewmate!!!!
