'Dapper Slapper' Devon Schwan Gets Slap Nickname Tatted on His Palm!

Devon Schwan is a fitness freak — a former competitive bodybuilder who realized he also has a talent for violence. 

He's also so passionate about Power Slap, he got his nickname -- The Dapper Slapper -- tattooed on his palm!

Schwan took up MMA in 2007 and burst onto the scene — racking up a slate of impressive victories and even became a playable character in several video games, including Supremacy MMA for PS3 and XBox. 

So, what drives Devon?

“A love of competition, a fear of losing, a fear of being average, and most importantly .., everyone who has ever doubted me … success is by far the best revenge!”

Bef0re Devon took on the name "Dapper Slapper," he went by “Savage” -- and if you're wondering why?

“I suppose from kneeing fools in the face!”
