His Japanese origins as Oroku Saki and brotherly relationship with Hamato Yoshi is mostly intact, with the Foot Clan and the Hamato Clan being later revealed as having a long-term rivalry before the Hamato family killed the Oroku family, wiped out their entire clan (starting with the destruction of the Foot Clan monastery) and took in the orphaned Saki as their own. Despite being raised as brothers, both Saki and Yoshi eventually became rivals due to the love of Tang Shen, whose decision to marry Yoshi drove Saki to discover his true heritage and turn on his former brother, eventually destroying everything Yoshi held dear, including the lovely Tang Shen (whom he had killed by accident) and the entire Hamato Clan (starting with the destruction of the Hamato Clan monastery, which resulted with Saki's head getting burned scarred and hairless). Blaming Tang Shen's untimely death on Yoshi, Saki returned to his biological family and became the new leader of the newly restored Foot Clan, tutoring ninjutsu students such as world-famous martial artist Chris Bradford and Brazilian street thug Xever Montes, sharing criminal business with business partners such as Russian arms dealer Ivan Steranko, Sicilian mob boss Don Visiozo, and Purple Dragons leader Hun. In addition, he also a pet akita named Hachiko (named after the akita of the same name) who played a part in Bradford's mutation into Dogpound after Hachiko bit him.
