Foot Clan is a fictional ninja clan in the Teenage Mutant Ninja Turtles comics and all related media and are the main antagonist faction. It is led by the devious Shredder and his second in command Karai. The Foot Clan was originally a parody of the criminal ninja clan The Hand in the "Daredevil" comics. In addition to the obvious similarity in their names, both clans originate from Feudal Japan, practice ninjutsu and black magic, and are now powerful global organized crime rings who are familiar with multiple illegal activities such as drug smuggling, counterfeiting of money, gunrunning, murder, assassination, computer hacking, theft, and terrorism.
