How to Deal with a Problem
The difficult thing about making up ridiculous superheroes as a joke is that it’s next to impossible to out-ridiculous the actual comic book industry.
I picked the name “Legion of Superheroes” thinking it was far too clunky to have ever been used for real, but it was, by DC. According to Wikipedia, “Lightning Boy, Saturn Girl, and Cosmic Boy, were members of a "super-hero club" called the Legion of Super-Heroes.”
You have to wonder why they went with “Cosmic Boy,” over “Cosmic Kid.”
Later members included Bouncing Boy and Matter-Eater Lad. I’ll let you guess which is which.
