Gene Simmons Underbite KISS

By day, Gene Simmons looks like a guy named Lester who would hit on you at his grandmother's funeral. By night, Gene Simmons is fully costumed as The Demon of KISS, the legendary rock band whose songs suck but whose shows rock. The Demon might be a little less sinister after you know he has an underbite in real life, but Gene Simmons is really a good guy. Seriously.

Gene Simmons' KISS character The Demon is far less intimidating when the makup comes off and you find out he has an underbite. Good guy though.
