Confidence, uniqueness and charisma.
These are just some of the traits that are integral to the art of cool.
In mixed martial arts, many fighters and industry leaders can be considered popular, but few have the characteristics that go with being cool.
Here are the 10 people in MMA that epitomize coolness.
Not the most popular fighter in the United States, Yoshihiro Akiyama is, however, a superstar in Japan.
The well-dressed and tanned veteran has earned the moniker "Sexyama" for his GQ style. His wife is also a very famous model in Japan.
Akiyama has the classy coolness that differs greatly with the edgier looks that other fighters in MMA sport.
The former WEC champion has a California type of cool to him, with his easy-going ways and chill personality.
Never too serious, unless it's during a fight, Urijah Faber remains one of the most popular lighter-weight fighters in the sport and is the poster boy for the smaller guys in the UFC.
Always keeping his composure as he referees inside the Octagon, Herb Dean has become popular among fans for his top-notch officiating and knowledge of the sport.
At one point in his life, Dean even tried his hand at fighting inside the cage. Although not as successful as his refereeing career, Dean clearly obtained a lot of experience that makes him the consensus best referee in the game.
Dean is the coolest referee in MMA with his great calls inside the Octagon, knowledge of the sport and also for his unique style (Dean is the only referee I know who can pull off the dreads).
A former WEC and current UFC ring girl, Brittney Palmer is much more than just eye candy.
Taking time off from the UFC to pursue her passion for art, Palmer has an artsy, almost hipsterish cool side that fans may not have known.
Still working on her art as well as a new clothing line, Palmer will bring her coolness back to the UFC as the promotion heads to Toronto later this month.
Chuck Liddell pioneered MMA cool and contributed to making the UFC the most popular promotion in the world.
With his mohawk, tattoos and heavy hands, it's the Iceman's chill persona that keeps winning over fans.
Appearing on such popular programs as Blue Mountain State and a host of other movies and television shows, Liddell continues to be one of the coolest guys in the sport, even after retiring.
Anderson Silva has really upped his cool factor in recent months, as he looks to further his status as one of Brazil's most popular stars.
Another fighter with a great sense of style and a unique personality that's enthralling fans in his native country, Silva is kicking his way into becoming a pop culture icon.
His recent appearance on stage with Justin Bieber may knock him down a few pegs on the cool scale, but Silva makes up for it with his great dance moves and surprisingly humorous acting ability in the comedic ad campaign for Ford in Brazil.
One contributing factor of coolness is being at the forefront of trends, something Joe Rogan has been doing for years.
He was at the dawn of the reality show phenomenon in the early 2000s, hosting the widely successful Fear Factor, which will now be returning to NBC next year.
Within MMA, Rogan has been a long-time commentator for the UFC, starting when the sport was still widely considered to be barbaric and underground.
Rogan was at the genesis of the UFC's rise to popularity, making him all the more cooler now that the sport is going mainstream.
UFC Welterweight champion Georges St. Pierre is easily one of the most recognizable MMA figures in North America, if not the world.
Always looking classy in his tailored suits at press conferences, St. Pierre can definitely sport that James Bond look.
With his high-level sponsorships, numerous magazine covers and many other media appearances, St. Pierre is the squeaky clean, yet stylish face of the sport.
Going from a relative unknown prospect to the most talked-about champion in the UFC, Jon Jones is one of the coolest cats in the sport.
Personable, a little cocky and having a great sense of style (and of course the amazing fighting ability), Jones has become one of the most popular fighters in MMA and only looks to continue on his meteoric rise.
Success may have gone to his head a little bit, but as long as Jones keeps winning, his popularity among fans and charisma with the media will keep him as one of the coolest fighters in the sport.
As the head of the biggest mixed martial arts promotion in the world, Dana White has created an entity that is now one of the most popular sports in the world.
With all of this success, White has become the premier mogul of the industry and now has ties with all manners of people, including celebrities at the forefront of pop culture.
On his own, White is a fiery yet laid back guy who has become one of the coolest figures in the sport.
