Doppleganger will serve as the main bad guy, because a doppleganger is probably the best for epic chase scenes, because they can take the image of anyone they see of relative size. dopple is a demon from a world that was banished from this one many years ago when he tried to live in peace but was shunned by society for being everyone at the same time... He made the promise that he would come back to destroy that which tried to destroy him. In your missions he gets released, no matter which side of the story you are on. He takes the image of one of your crew members and kills him. He goes off in which point you get the option to fight with , against, or just hang out...

Dopple is pretty evil at heart, because of his society induced sick intentions with the world.

There aren't really and physical stats with him, because he can take the form of anyone he sees... Just know that if you have suspission of someone acting weird... then its probablly Dopple.
