The only child of the Maybe family and a relative of the wealthy Yess family (a family of trouser makers), he was a child genius and serial killer. (His middle name is Janet because his parents wanted a girl.) He deliberately kept his high intelligence secret, by learning to spell badly and act stupidly, in order to avoid getting caught. He killed for the first time at age 12, by murdering a neighbourhood couple whom he chose at random from the phone book, as an experiment. He moved on to gradually killing members of the Yess family, setting things up so his father could assume control of the company. After being apprehended by Judge Dredd, he was sent to an asylum.
