Here are just a couple random MUSCLE dudes for your viewing pleasure. I know these guys have legit names, but part of the fun of these was always making up their names and bios, so these are merely my silly interpretations:
Jazz Man! This guy always reminded me of the G1 Transformer Jazz.
The Amazing Two-Ply! He'll wipe the floor with you, and wipe your ass too!
The Troublesome Tribble! Watch out, he multiplies!
