UFC heavyweight champ Junior dos Santos is widely known to be a nice guy, rarely breaking form from his generally humble demeanor and constant stream of smiles. However, “Cigano” also wants the world to know he’s also extremely “bad”, at least when it comes to finishing off foes inside the Octagon that is.

The 28-year old is 15-1 thus far in his career with ten straight wins including those over a murderer’s row of competitors like Fabricio Werdum, Stefan Struve, Gabriel Gonzaga, Roy Nelson, Frank Mir, Shane Carwin, and Cain Velasquez. In doing so, Dos Santos believes he’s earned the right to say he’s the most dangerous man in the world when it comes to hand-to-hand combat.

“Baddest man on the planet. That’s who I am, and what I want to be for a long time,” admitted Dos Santos in an interview with the Los Angeles Times.

Dos Santos plans on proving his status is legitimate in late December when he faces Velasquez in a rematch at UFC 155, a former title-holder himself whose only loss came against the current divisional king a year ago. The hard-hitting Brazilian understands Velasquez is a dangerous opponent who may not fall as quickly as he did in their initial encounter, but in the end he is certain the same result will be produced.

“I beat him (once) and I will beat him again,” stated Dos Santos. “I believe I can keep the fight standing, but it doesn’t matter much. If he gets me down, I’ll either get back on my feet, or, if he holds me there, I’ve been working hard on my jiu-jitsu, so I’ll work to submit him. This can be my first submission.”

With an improving arsenal of abilities and the confidence of a dominant champion, it’s hard to dismiss the possibility of Dos Santos putting away Velasquez on the ground, an outcome moving “Cigano” one step closer to consideration as one of the best heavyweights MMA has ever seen.

On a side note, the surging stand-up specialist actually has two tap-outs on his record, though one came against Mirko Filipovic and was the result of strikes. His other involved a Guillotine Choke in his second professional fight nearly six years ago.
