The Magnavores left a baby at Hillhurst. Little did they know, the baby was really Rocket Man in disguise. Rocket Man was a blue robot that fired blinding flash bombs. 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.
