Booby is a female Majin spawn created by Majin Boo in a quest to find a love partner. In 790 Age, Majin Buu accidentally reads one of Mr. Satan's adult books, Bob and Margaret’s Forbidden Games, causing him to long for love. He obtained ideas about female mates and ultimately create his wife, Booby, from a part of his own body, and also hit her with his Love Beam. This caused her to give birth to Baby Buu. The family grew quickly and was later recognized as its own race, which is seen in Dragon Ball Online. The image used is not the character Booby, but an original created character called Majin Lamp created by the user epe-tohri.
