Boogerman

One dark and stormy evening, the civic-minded Professor Stinkbaum was working in his lab where he was secretly building a machine that would save the world from pollution by transporting it to a place he called Dimension X-Crement. That same evening, eccentric millionaire Snotty Ragsdale paid a visit to the lab to investigate this project and find out how such a thing was possible. When the machine was activated, a cloud of pepper was inhaled through the nose by Ragsdale, causing him to let out a mighty sneeze that broke the machine and opened a portal. Just then, a mysterious giant arm pops out of the portal and steals the machine's main power source. In response to this danger, Snotty rushes into the men's room to change into his alter ego, the mighty Boogerman!

Boogerman was a bonus character in the third Clay Fighter game.

Fighting Freaks
Boogerman defeated Meat, and then the tournament was cancelled. So that's cool.
