In "A Monster is Born," the Magnavores left a baby at Hillhurst. Little did they know, the baby was really Rocket Man in disguise. However, Rocket Man briefly reverted to a baby-like persona when Flabber materialized an over-sized bottle to distract him. The Beetleborgs took the window of opportunity and defeated him with the Sonic Lasers. He is mentioned as being from issue #148.
