Foot Clan
In this endeavor, the Foot Clan also came into contact with the extradimensional warlord General Krang who also wanted to create a mutant army to meet his objectives. An attack by the Foot Clan in the laboratory of Krang's ally Baxter Stockman led by a combination of circumstances to the creation of the Turtles and their father Splinter (who in a previous life had himself belonged to the Foot Clan).
