Comics
In 1968 and 1969 DC Comics licensed CAptain Action, Action Boy and Dr. Evil from Ideal Toys and released 5 issues of a comic book series. Action Boy was featured in all 5 issues and was cast as Captain Action's son, Carl Arno, AKA Action Boy!
In 2008 Action Boy was brought back to the comic world with Captain Action and Dr. Evil in tow in an all new series from Moonstone Books with new back story written by Fabian Nicieza. Action Boy is an adult now and is not cast as Captain Action's son, but merely as his former sidekick, trained by the same A.C.T.I.O.N. Directorate who trained Captain Action.
Sources at Moonstone tell us that an Action Boy one shot may be in the works in the near future!
