Орочі Кацумі

Yūko Maekawa - A 3rd dan, Doppo's son and current prodigy of Shinshinkai karate. He fights Roland Gustof in round 1 defeating him easily before fighting Hanayama Kaoru and fighting a more even round 2 using his sonic fists technique. In round 3 he loses miserably to Retsu Kaioh getting knocked out in 1 punch. Retsu was impressed that Katsumi could take one of his punches. A rematch in the 'Search of Our Strongest Hero' series is interrupted when the convict Dorian comes into the Shinshinkai building and attacks Katsumi. Katsumi also later trains the convict Doyle in Shinshinkai Karate. In the anime it is revealed that Doppo is actually Katsumi's adoptive father.
