UFC fighter Clay Guida (white shorts) celebrates after defeating Rafael Dos Anjos (not pictured) during the lightweight "swing" bout in UFC 117 at the Oracle Arena.
While he made headlines recently for his brief banishment from the UFC after an objectionable joke he made in a tweet, Torres always seems like he's having fun in the Octagon. And it's not just because of his awesome mullet.
Anyone with a physique like Nelson's and a nickname like "Big Country" has to be fun to be around, doesn't he? Nelson's shown a great sense of humor in and out of the Octagon and has won over many fans.
It takes a real man to fill the role played by Mr. T in the "A-Team" movie. While he's had his run-ins with the law, Rampage continues to be a fan favorite while remaining among the top light heavyweights in the UFC.
He may be kind of mild-mannered and thoughtful outside of his day job, but once it's fight time Mir turns it up several notches. He's been one of the top heavyweights for some time and shows no fear inside the Octagon.

GSP is at or near the top of most pound-for-pound lists, and the UFC's welterweight champion has become one of the sport's crossover stars, appearing in commercials all over the world. The Montreal native is currently laid up with a knee injury, and his large presence is greatly missed in the Octagon.
Griffin is considered one of the UFC's funniest and quirkiest fighters. He's laid back, self-deprecating and has one of the most unique senses of humor you'll ever come across. He may cross a line once in a while, but it's generally in the name of humor.
He calls himself "Meathead." How can you not consider Mitrione a great personality based on that alone? The former NFL defensive lineman with the New York Giants and Minnesota Vikings is always entertaining at UFC press conferences.
When the UFC needs a welterweight to fight on short notice, they know they can turn to Koscheck. He's fought a UFC-high 19 times since 2005, and never fails to bring the trash talk to get an opponent riled up.
One of the original breakout stars from the UFC's early days, Ortiz was known as "The Huntington Beach Badboy" for many years, living up to the role with a rocky relationship with his porn-star girlfriend (Jenna Jameson). As his career nears an end, Ortiz has changed his nickname to "The People's Champion."
Known as "The Count," you can always count on Bisping bringing the trash talk, before and after a bout. He's fearless and talented and can be one of the UFC's most polarizing figures.
Based on his part-time job during his early days in the UFC, Guida is known as "The Carpenter." He lives in an RV near his training base in New Mexico and drives it to many of his fights. Just too cool.
With his trademark cowboy hat atop his head pre- and post-fight, Cerrone lives up to his nickname of "Cowboy" by living on a 10-acre complex he calls "TapOut Ranch." Cerrone fought five times in 2011, going 4-1 on the year.
"The California Kid" is another of the UFC's crossover stars. With his good looks and big smile to go along with world-class skills in the Octagon, Faber is one of the top names in the biz. Faber recently shaved off his long locks in solidarity with his younger sister who had to undergo brain surgery after a car accident.
Sonnen is the reigning king of UFC smack talk. Whether he's telling you he's the "real" middleweight champion (despite the fact he was submitted by belt-holder Anderson Silva after thrashing Silva for most of their fight in 2010) or spouting off on any number of subjects, Sonnen is never at a loss for words. He's also had his share of trouble, having been suspended for testing positive for PEDs and pleading guilty to money laundering charges in a real estate fraud case.
Anyone known as "Mayhem" must have a big personality. While he hasn't had much success in the UFC, he's won his fair share of lower-level bouts. But it's his mouth that brings in the big bucks, as he co-hosts "Mayhem Mondays" on The Jason Ellis Show on Sirius satellite radio. He also is a TV personality, hosting a reality show called "Bully Beatdown," which airs on MTV.
