Kingdom Come
Offspring initially appeared in a self-titled one-shot issue which was released as a tie-in to the series The Kingdom. This series takes place in an alternative universe to the main DC Comics universe.[1] Offspring later appears in the final issue of The Kingdom, where he works with Kid Flash, Nightstar, and Ibn al Xu'ffasch to combat Gog. He is treated as a joke professionally and personally by his friends, family, and even foes. However he learns to accept his place on the team as the funny member. His relationship with his father is close and happy; his girlfriend, Micheline, is unhappy with the lack of respect his goofy behavior is causing.[2]
Mainstream continuity
In the series JLA, it is revealed that the Plastic Man of the main universe has a son named Luke McDunnagh – his illegitimate child by "Angel" McDunnagh – who has powers greater than his own, with the ability to easily change his color and mass as well as his shape. When Luke becomes involves with a gang, Batman intimidates him into leaving the gang and going back to his mother. Batman is disappointed in Plastic Man for being a poor father and advises him to consider getting back in touch with his son.[3]
After Plastic Man is recovered from beneath the ocean, he takes time off to be with Luke, even mentally programming himself to forget his heroic identity and powers. Luke and Batman convince him to go back to action when Martian Manhunter regresses to a 'Burning Martian' identity, as Plastic Man was the only person capable of opposing him due to his immunity to psychic abilities.
Offspring appears briefly serving as a member of the Titans during the one year jump following Infinite Crisis.[4] In the series 52, Offspring assists Steel in launching an attack on LexCorp when Lex Luthor kidnaps Steel's daughter Natasha. Offspring later appears in World War III, where he unsuccessfully tries to defeat Black Adam by grasping his brain from the inside.
Offspring is among the young heroes who are captured and brainwashed into fighting at the Dark Side Club. After being rescued by Miss Martian and Ravager, Offspring is offered a spot on the Teen Titans by Wonder Girl. Like most of the other survivors, he declines.[5]
Following the DC Rebirth relaunch, Luke is reintroduced with roughly the same powers and personality, living with his birth mother Angel. He is reluctant and angry at his father for not meeting him for years (as Plastic Man was trapped in an egg-like form). However, Luke relents after the two play a game of basketball and he is given a ride in the Batmobile. Luke goes on to join the Terrifics as Offspring.[6]
