Peek-a-Boo is a choujin that starts his matches as a baby, as Strong the Budo forces him to revert to a baby form after every match that he wins. He learns with the speed of a baby and is able to assimilate all of his opponent's moves with ease, but struggles to remember basic moves once he reaches an adult form.
