Though his last few fights at lightweight didn’t go so well and he’s currently trying to make his way through the world of welterweights, it’s easy to forget that for a while there, Rafael dos Anjos was a total badass who ruled the 155-pound weight class with an iron fist.

In fact, it was those iron fists that often sent opponents to the canvas. Donald Cerrone, Benson Henderson and Jason High all got pretty much wrecked by Dos Anjos’ Brazilian knuckle-sandwiches, and since seeking his fortunes in the 170-pound division, his ability to knock people silly has helped him find success.

On Saturday, Dos Anjos will take on former welterweight champ Robbie Lawler in the main event of UFC on FOX 26. Lawler is another fighter known for wielding heavy hands, so you can expect some killer violence to go down.

Here’s Dos Anjos in action.
