Mervin Monroe - Radioactive Man

Radioactive Man 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 #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. In one episode of The Simpsons, 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.

Outside of 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. The character has also appeared in issues of Simpsons Comics and Simpsons Super Spectacular, and in the 1992 video game Bartman Meets Radioactive Man.
