In the 2012 series, the Foot Clan's origins are expanded on in the second season of the series. The clan was founded in 512 A.D. in Japan by a master martial artist named Koga Takuza, who used the swords of his fallen foes to forge a helmet stronger than steel, dubbing it the Kuro Kabuto. The Kabuto helmet is a symbol of the leader of the Foot Clan, passed down to the various rulers in the Foot's history. The Foot Clan would end up in a lengthy war against the Hamato Clan, which reached a boiling point when Oroku Saki was raised alongside Hamato Yoshi. Though the two were raised as brothers, Saki discovered his true heritage as being an orphaned Foot Clan member, and when his love Tang Shen wed Yoshi, he inadvertently killed Shen leaving Yoshi to perish while saving his infant daughter Hamato Miwa. Saki rose in the ranks to become the leader of the Foot Clan, tutoring several worthy pupils such as world-famous martial arts star Chris Bradford (who would later be mutated into Dogpound and later Rahzar) and Brazilian street thug Xever Montes (who would later be mutated into Fishface) and sharing business with business partners such as Russian arms dealer Ivan Steranko, Chinese-American Purple Dragons leader Hun, and Italian mafia boss Don Vizioso. In this series, the Foot Clan is a global ninjutsu clan answering only to the Shredder, though others run the various factions of the Foot Clan across the globe.
