List of recurring The Simpsons characters

Radioactive Man (voiced by Harry Shearer) is a fictional comic book superhero. The character was heavily featured in the episodes "Three Men and a Comic Book" and "Radioactive Man". Within the ''Simpsons'' universe, he was created by Morty Mann. He has been portrayed in many media since his debut in ''Interesting Stories'' No. 27. The first issue of ''Radioactive Man'' appeared in 1952. He was featured in at least one 1950s era black-and-white serial, sponsored by Laramie Cigarettes. There was also a campy early 1970s television series resembling ''Batman''. This version was played by an actor named Dirk Richter, who was allegedly murdered in a brothel some time after the show ended, a parody of George Reeves and the controversy surrounding his death. In the episode "Radioactive Man", a Hollywood studio attempted to film a Radioactive Man movie in Springfield. The movie starred Rainier Wolfcastle as Radioactive Man. The role of Fallout Boy, Radioactive Man's sidekick, was cast from local children and went to Milhouse Van Houten. The movie was never completed due to budget overruns caused by constant price-gouging by Springfield vendors, and Milhouse snapping from the pressure of the role, and refusing to continue to portray Fallout Boy. A last-ditch attempt at replacing Milhouse with Mickey Rooney fails, and the movie is cancelled.

Outside ''The Simpsons'', the Radioactive Man character also appeared in a real comic book series based on him that was first published by Bongo Comics in 1993. The Bongo comics expanded more on the character, including his powers, giving him several which parodied those of Superman including super speed, flight, and the power to fire beams of "clean, nuclear heat" from his eyes. In the comics, his regular personality, Claude Kane III, is seen as a useless layabout. Claude's main love interest, journalist Gloria Grand, has little interest in him and dismisses him as a 'rich kid'. The character has also appeared in issues of ''Simpsons Comics'' and ''Simpsons Super Spectacular'', and in the 1992 video game ''Bartman Meets Radioactive Man''. Provided by Wikipedia
