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) from Korea who had never been knocked out before on his K-1 career until Mighty Mo (185 cm) 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)" resulting in a KO in favor of the shorter in K-1 history and possibly in kick-boxing as well as in boxing in history (Nicolai Valuev, 213 cm, is only 28 cm taller than Ruslan Chagaev - 185 cm). But on December 31, 2007, at the K-1 Dynamite Tournament in Osaka, the record was surpassed by Danish Karate fighter Nicholas Pettas (180 cm), who was able to KO the 217 cm Korean Kim Young-hyun (37 cm height difference).
