Karapet "Karo" Parisyan (born August 28, 1982) is an Armenian-American mixed martial artist, who last competed in the welterweight division. A professional MMA competitor since 1999, Parisyan is a former WEC Welterweight Champion and has also competed for the UFC, Bellator, and Impact FC.

Parisyan was born in Yerevan, Armenian SSR (today Armenia). His family migrated to America when he was six years old. Parisyan started training in judo when he was nine years old under fellow Armenian Gokor Chivichyan. Parisyan stated that his father began taking him to judo lessons because he beat up on his sisters and judo would be an effective outlet for Parisyan to take out his anger. In a book he published, however, Parisyan wrote that his father introduced him to judo to cure his laziness. By age ten, Parisyan was training his Judo under both Chivichyan and Gene LeBell.

Hayastan Grappling System

For more than thirteen years, Parisyan developed under the Hayastan Grappling System (aka Hayastan Wrestling), a style developed by Gokor Chivichyan and Gene LeBell, which blends elements of Judo, Sambo, Catch wrestling, Greco-Roman wrestling and Freestyle wrestling. Parisyan continued to train at the Hayastan Academy under Gokor and Gene until late 2005. In early 2012, Karo mentioned in an interview that he has returned to the Hayastan Academy.

Judo

Parisyan has six Junior National belts to his credit and competed in the Olympic Judo trials ahead of the 2004 games in Athens. He wrote that going to the Olympics was his dream and that mixed martial arts was only an outlet for his boredom. During the trials, he received a call from UFC management and was invited to compete. He accepted because he needed money. But after the fight against Dave Strasser, his ribs needed recovery and he decided to give up on the trials.

He lost his first fight to Sean Sherk by a controversial decision. In an immediate rematch, Parisyan was unable to come out of his corner, and later explained he had been suffering from a stomach virus.

After recovering from his back injury, Parisyan returned at UFC 94 on January 31, 2009 in Las Vegas against Dong Hyun Kim. Parisyan defeated Kim in a controversial split decision. Following the fight, Parisyan tested positive for banned painkillers hydrocodone, hydromorphone and oxymorphone. Parisyan has stated that he has a prescription for the medications due to a severe back / hamstring injury. Parisyan was suspended pending a full hearing in mid-March. On March 17, 2009, the NSAC suspended Parisyan for nine months and ruled his decision victory a "no contest".

Parisyan was scheduled to fight Dustin Hazelett at UFC 106, but pulled out of the fight on November 19, the day before weigh-ins. UFC President Dana White responded to the situation on his Twitter stating that Parisyan will "not be fighting Saturday or ever again in the UFC!!" White also stated that he had "a laundry list of excuses." Later that day, Neil Melanson, a longtime friend and training partner of Parisyan's, divulged to MMA news site Five Ounces Of Pain that Parisyan has been battling an addiction to painkillers dating back to an injury suffered while training for a fight.

Independent promotions

Karo fought highly touted Canadian prospect Ryan Ford on May 19, 2011 in the MMA Live 1 show in London, Ontario, Canada. He was able to neutralize Ford's strength and power by applying his takedowns, as it seemed that the first and second rounds were in favor of Parisyan, but was caught in the third round by a vicious knee to the head which resulted in a cut over Karo's left eye that would end the fight via TKO due to a doctor's stoppage.

Parisyan fought Jordan Smith on September 14 in Brazil, Amazon Forest Combat 1. After a long hard battle going the distance, Parisyan came up short, losing the fight by split decision.

Parisyan was scheduled to fight Shamar Bailey in the main event of ShoFIGHT 20 in Springfield, Missouri for the vacant welterweight title on June 16, 2012.

After being stunned by a knee from Gunderson, which resulted in a broken cheek bone, Parisyan was caught in a guillotine choke and lost the fight by submission. Parisyan said after the fight that he tapped due to the pressure on his cheekbone and he wasn't being choked.

Parisyan was expected to fight David Bielkheden in Malmo, Sweden on October 6, 2012 but pulled out of the fight due to personal reasons and was replaced by Marcus Davis. Parisyan said at the time: "Everyone knows that it has been a rough road for me over the past couple years. I've tried to just refocus myself and get back to throwing people on their heads, but it hasn't been the same. Not to take anything away from my opponent, but my last fight was devastating for me. My manager and I had a long talk, and he set me up with a sports psychologist. At this point, I need to listen to my doctor and refocus on my life -- not fighting. God willing, fighting will be back in my life at some point, but for now I need to only focus on Karo getting back to Karo."

Parisyan defeated Tiger Bonds via first round armbar on September 29, 2012 at a Gladiator Challenge event.

Parisyan then fought on October 28, 2012 against Edward Darby and won via first-round armbar.
