The Doppelganger, as his nickname implies, he's a shapeshifting otter capable of replicating another character's voice, appearance, personality, and general abilities using seemingly supernatural imitation abilities. Doug also seems to possess an uncanny ability to surmise a victim's psyche or at least guess their own memories. During a trivia test, he was able to correctly answer deeply personal questions about Rigby.
