The 1987 series and the spin-off "TMNT Adventures" comics share a similar continuity, and thus the same version of the Foot Clan. The Foot is an ancient ninjutsu clan, founded in Japan in 1583. The Shredder, followed by the Turtles and Splinter, went back and forth in time to try to kill the creator of the Foot Clan. In 1583, Shredder's ancestor Oroku Sancho led a small group of samurai, and Shredder offered to help him find magical artifacts that would give him power and wealth beyond his wildest dreams. Meanwhile, Splinter's ancestor Hamato Koji had been sent to find the same artifacts and did find them with the help of his descendant and the Turtles. One of the artifacts released a dragon, which headed for nearby villages; Splinter and Koji went to stop it while the Turtles went to fight Shredder. Sancho's men captured the Turtles and were about to execute them when Koji arrived, riding the dragon, which he had tamed. Seeing this, Sancho fled in fear, and Koji offered to lead Sancho's men and teach them the ninjutsu art of Shibana-Sama, founding the Foot Clan, so named for the footprint of the dragon in which he stood as he made his speech. (However, according to "Blast from the Past", the Foot was founded by the noble warrior Shibana-Sama).
