John Moraga (born March 20, 1984) is a Mexican-American mixed martial artist who fights in the flyweight division. He is currently signed with the Ultimate Fighting Championship.

Moraga started his professional career at 2009 in Arizona for the local organization Rage in the Cage. There he achieved an undefeated record of 6-0, until his fight against John Dodson at 2010, in which he lost by unanimous decision. After this setback he won four straight bouts to make his way into the UFC.

Moraga was expected to face Ian McCall on August 4, 2012 at UFC on Fox 4. However, McCall was forced out of the bout with an injury and was replaced by Ulysses Gomez. Moraga won his UFC debut via KO in the first round.

Melvin Paul Guillard, Jr. (born March 30, 1983) is an American mixed martial artist currently fighting in the lightweight division for the Ultimate Fighting Championship (UFC). He debuted with the company on The Ultimate Fighter 2 television series, losing in the first welterweight elimination bout to Josh Burkman. Guillard received his blue belt in Brazilian Jiu-Jitsu under Ricco Rodriguez in 2008. He is currently ranked as being the 15th best lightweight fighter by The USA Today Consensus Rankings, and 7th by MMAWeekly.

In 2005 Guillard fought against fellow future UFC veteran Roger Huerta. After Guillard took a competitive decision victory, the fight was ruled a no contest after Huerta appealed the commission making an accusation that Guillard was greasing between rounds and that he was very slippery since the start of the 2nd round.

Guillard later participated in The Ultimate Fighter 2, but was eliminated from the competition after losing by unanimous decision against Josh Burkman. Guillard returned at the season finale, defeating Marcus Davis by technical knockout due to a cut. Fighting again at welterweight, Guillard lost his next fight, against Josh Neer, by triangle choke submission which surprised many in attendance. Guillard seemed to control the fight until then, opening a large cut on Neer's forehead in the process.
