Keniuchio Harada is the mutant, illegitimate child of the former Japanese crimelord Shingen Harada, head of the Clan Yashida. Trained in the techniques of the samurai, Harada became a mercenary, working for a variety of employers, including the Mandrill and Viper. Following his father’s death, Harada sought to take control of the family from his half-sister, Mariko Yashida, but Wolverine stopped his plans. Later, following Mariko’s death, Harada succeeded in taking control of the family business and has been building their criminal empire since.
