Ostensibly a man who either is or has something to do with a triangle. Hates Particle Man and Person Man. Wins every fight.
Triangle Man, Triangle Man,
Triangle Man hates Particle Man,
They have a fight, Triangle wins,
Triangle Man!

A naturally thin man who works only upper body until said upper body becomes a triangle shape. Is usually accompanied by a "stick-up-the-ass" walk, tight spandex shirts, and an ego of unbelievable size.
"Look at Triangle Man over there flexing, I could snap his legs in half with my pinkies!"
