Vagner Rocha is a bad, bad dude.

The former UFC fighter and grappling ace Rocha took on Alex Marin at XFN 21 in a combat jiu-jitsu showdown—and the result was brutal. 

While Marin came into the bout well prepared, he was no match for the black belt Rocha, who dominated from the get-go before finishing with a rarely seen submission. 

Watch the full match embedded above, then catch Rocha vs. Mendes live Friday, Oct. 12 at 5:30 PM ET at Fight 2 Win 89 in Miami.
