Klaus

This is a MALE character

He seems like a shy type with a nervous attitude but he's actually very judgemental towards people he finds unworthy and has the ability to switch personalities from a reserved kid who is annoyed by the world to an overdramatic fighting machine that enjoys the taste of blood. He is half human half ??? because they don't know what his father was but his blood makes him have problems. Klaus has a voice in his head that talks him into doing things or bothers him enough until he does it. (there will be a little creature he can only see be added later)
