Radiation Dude

Radiation Dude is a comic book series sold at The Android's Dungeon & Baseball Card Shop. It is a clone of the popular  comic book series.

History
Radiation Dude can be seen on a rack of comics at The Android's Dungeon. When Bart comments that all the new superheros suck, Milhouse contends that the only good one is Radiation Dude. Bart then goes on to explain that Radiation Dude is nothing more than a cheap imitation of, citing his clever catchphrase, "Up and atom!" whereas Radiation Dude's catchphrase is simply "Up and let's go."

The character is very similar looking to Radioactive Man, the only major difference between the two being the color scheme of their costumes.

Behind the Laughter
The comic is a reference to the fact that most good comics spawn lousy imitations.
