Riddiance is the main villain from Paper Mario: The Benclank Battalion, although it is not revealed until the end of the game that he has been possessing Benclank. Before he appeared in that game, his backstory was revealed in Benclank's Gone: The Story.
Personality and Abilities
Riddiance, having been created at the dawn of time from all things Chaotic, is not the nicest creature. He has terrible grammar, hardly ever making sense, and often changing the subject. He can possess almost anything, ranging from Benclank, to End Boss, to even The Snarl.
