Kickboxing Mighty Mo made his K-1 debut on February 15, 2004, at "K-1 Burning" event in Japan against
Hiraku Hori. He knocked out Hori at 1:22 in 4th round by right hook. After losing in semifinals at his first 8-man tournament in Las Vegas against fellow American
Dewey Cooper, Mighty Mo made a huge comeback four months later at the
Battle of Bellagio II, winning his first K-1 GP Championship by knocking out
Brecht Wallis in 2nd Round at the tournament finals. After a year off from
K-1, he made his comeback on March 4, 2007, at
Yokohama, Japan. His opponent was
Choi Hong-man (218 cm/7′2″) from Korea who had never been knocked out before on his K-1 career until Mighty Mo (185 cm/6′1″) managed to land his trademark right overhand punch, winning the fight by
KO at 0:50 KO in 2nd round. At that time, he held the record for the "Biggest height difference wins (33cm/12.9inches)" resulting in a KO in favor of the shorter in K-1 history. But on December 31, 2007, at the
K-1 Dynamite Tournament in Osaka, the record was surpassed by Danish
Karate fighter
Nicholas Pettas (178 cm/5′10″), who was able to KO the 217 cm/7′1.½″ Korean Kim Young-hyun (39 cm/15.3inches height difference). In professional
Boxing the record stands at 38 cm/14.9inches height difference when Randy Davis (1.80m/5′11″) knocked out Tom Payne (2.18m/7′2″) in 1985. On April 28, 2007, Mo entered the
K-1 World GP 2007 in Hawaii tournament as a heavy favorite. He knocked out all three of his opponents and earned himself a spot in the

Super Heavyweight Champion
Semmy Schilt by unanimous decision at the
K-1 World GP in Amsterdam. Semmy used his reach to keep Mighty Mo at bay, and Mo was unable to get in close enough to land his devastating overhand right. Rumors surfaced that Mo was nursing a knee and hand injuries from his previous fights. He had fought 7 times in the last 4 months. At the
K-1 Final Eliminations 2007 on September 29, he faced
Choi Hong-man again and lost by unanimous decision. During the fight, he was kicked in the groin and was inexplicably ruled a
knockdown by the referee. He was quoted in the post-fight interview: "I feel I was robbed. I should have won. There was a lot of favoritism here. He must have picked up a new technique-a kick below the belt. So next time I'll wear a thicker
cup. And next time I want to fight somewhere else." In his next three fights he went 1-2, losing to
Paul Slowinski and
Keijiro Maeda before defeating Justice Smith on August 9, 2008. Mighty Mo had replaced
Andrei Arlovski at the
K-1 World Grand Prix 2010 in Seoul Final 16 held in Seoul against Romanian Raul Cătinaș and won by unanimous decision. As a result, Mo was the only American to make it into the
