Takeshi Tatsuo

Takeshi Tatsuo is the founder of the Foot Clan in Teenage Mutant Ninja Turtles (IDW). He was the samurai retainer of the daimyo Ashikaga Yuu, and was so fierce a warrior that Ashikaga himself even feared him. Ashikaga set a trap for Takeshi in the mountains where a legion of his armies awaited him. He slaughtered the lot of them, but at the expense of his right leg. He was saved by a mysterious mystic and had his leg restored to him; the bloodied footprint it left behind inspired the Foot Clan's name.
