The Naughty Djinn, Ba-Chien Myu was created by Ba-Chien Monteblanc, the great great great great etc. etc. Grandfather of Ba-Chien Monterei! She was originally a normal kitty, eating normal mice, as normal kitties are want to do. Ba-Chien Monteblanc decided he had had enough, and instead of killing her, turned her into his ultimate weapon. Unfortunately, a mouse having a cat for an ultimate weapon... it was a little problematic. She was imprisoned, and left on Mobius to keep from causing problems. Darn those decendants. Ba-Chien Myu is based on Majin Buu, from Dragonball Z.
