UFC 160: 'Bigfoot' Silva doesn't believe in MMA 'superheroes,' says no one is 'invincible' ahead of Cain Velasquez rematch

While some people don't believe "Bigfoot" actually exists, Antonio Silva, for one, doesn't believe in superheroes.

There are a select few in the mixed martial arts (MMA) community that aren't giving Silva much of a chance when he faces Cain Velasquez for the second time in a full calendar year at UFC 160 on May 25, 2013 in Las Vegas, Nevada.

You would think all of the doubters and naysayers would be getting on "Bigfoot's" last nerve, however, the massive Brazilian actually enjoys people counting him out. It's a motivational tool he uses to go out and perform and prove people wrong.

Just so he can have the last laugh.

And when he steps into the Octagon this Memorial Day Weekend to face the current Ultimate Fighting Championship (UFC) heavyweight champion, Silva is determined to prove that there are no superheroes in the sport of MMA and no fighter is invincible (sorry, Anderson Silva) and he plans to make an example out of "Brown Pride."

His words at this week's UFC 160 media conference call (listen to it here):

"I like when people underestimate me. It's nice. I get to go out there and get to prove them wrong. There are no superheroes in this sport. Nobody is invincible and I have been putting in a lot of hard work for the last nine weeks. I've been preparing myself and I am very confident that I am going to have my hand raised on May 25th."

"Bigfoot" was absolutely obliterated in his first encounter against Cain last Memorial Day Weekend, and fellow heavyweight contender Daniel Cormier thinks it will be much of the same when the two big men battle it out once more.

But, that was then and this is now.

Silva is riding high, fresh off two knockout victories over Travis Browne and Alistair Overeem, so you can't blame him for having the utmost confidence as he prepares to face a man who used his blood to paint the canvas red last May.

He's proved people wrong once before by smashing the heavy favorite Overeem at UFC 156, and he plans to do it again against Cain in "Sin City."

Anyone giving "Bigfoot" much of a chance in their rematch?
