Fallout Boy was
Radioactive Man's
sidekick from
The Simpsons and the short-lived
RM comic book. He wore a green costume and had basically no super powers, other than the ability to
fly. His secret identity, the name of which escapes me, lived with RM
batman style. He was once played by
Milhouse in an episode of the Simpsons.
