The heavyweight out of New Orleans needed just 4:48 to establish his dominance over UFC veteran Gabriel Gonzaga. Gonzaga, a veteran of 22 UFC fights, tried to exert his grappling prowess early on in the fight, even getting Lewis to the ground at one point. But as soon as "The Black Beast" found an opening, he capitalized in a big way.

The win was his sixth finish in as many UFC victories. Lewis posted a first-round knockout against Jack May in April 2014 and followed that up by crushing Guto Inocente with some vicious ground-and-pound two months later.

Even more impressive? Lewis has absorbed more than 10 significant strikes in only one of his eight UFC fights. "The Black Beast" is a bad, bad man.
