Siegfried is a squirrel who isn't a mutant and is part of the team trying to stop James and save the world. He is the son of Tristen, a heroic female gray squirrel who was in the first roleplay (she died fighting the mutants during the time lapse in between the end of the first RP and the beginning of this sequel - We Are Legend). He usually wears a blue hoodie and is brave, observant, and intelligent. He is on a quest to find a special sword his parents owned.
