Demetrious Johnson, better known as “Mighty Mouse” to the mixed martial arts community, is the first and current UFC flyweight champion, and will be defending his belt at UFC on FOX 8 in Seattle this Saturday.  The 5’3” fighter was born premature and raised in Parkland, W.A. by his deaf mother and an abusive stepfather.  In high school, Johnson wrestled as well as ran cross country and track and field.  Johnson began his mixed martial arts career in 2007 with a KO of Brandon Fieds at AX Fighting Championships 16. Less than three months later he traveled to California where he TKO’ed Pedro Mercado less than 90 seconds into the first round at King of the Cage: No Holds Barred. At AX Fighting Championships 20, he won two fights in the same night, defeating Jeff Bourgeouis and Eric Alvarez via unanimous decision.

Following the AX Fighting tournament, Johnson went on a tear around the Pacific Northwest, defeating his next five opponents via submission. He defeated Jose Garza by armbar, Forrest Seabourn and Frankie Mendez by rear naked choke, and Louis Contreras by both keylock and rear naked choke. Garza was the only opponent to make it out of the first round without being submitted. In 2010, Johnson capped his 10-0 start with a headkick KO of Jesse Brock. The Brock victory earned him his entry into the WEC.

Mighty Mouse made his WEC debut against Brad Pickett at WEC 48, where he lost by unanimous decision. He was taken down repeatedly throughout the fight, largely in part due to the size difference between the much larger bantamweights and his own diminutive frame. Following the Pickett loss, Johnson fought Nick Pace to a unanimous decision and submitted Damacio Page in the third round of his last UFC fight.  One event after his Page victory, the WEC was folded into the main roster of the UFC.  Johnson made his UFC debut at UFC 126 against Norifumi Yamamoto. At bantamweight he fought Miguel Torres to a unanimous decision, earning a title shot against Dominick Cruz.  He then went the full five rounds against Cruz, losing by unanimous decision.

Following the failed title shot, Mighty Mouse dropped to the newly added 125lbs division to take part in a four-man tournament to determine the inaugural flyweight champion of the UFC.  In the first round of the tournament Johnson met Ian McCall in Sydney, Australia.  At the end of the third round, the fight was called as a majority decision, however, at the post fight presser it was revealed that a mistake had been made and the judges had ruled the fight a split draw.  Denied the possibility of a fourth round to break the draw, the two combatants faced each other again three months later in Sunrise, F.L.  During their second match, Johnson won by unanimous decision.  He went on to the finals to defeat Joseph Benavidez via split decision.  He also defended his belt once against John Dodson, winning again by unanimous decision.

Mighty Mouse has not finished an opponent since November of 2010.  He has fought seven times in the Octagon, with each win coming by way of split or unanimous decision, and one draw. He will defend his belt once more against John Moraga on July 27, 2013 at UFC on Fox 8.  Moraga is riding a seven-fight win streak, and his last defeat was at the hands of former flyweight title challenger Dodson.
