Foot Clan
The Foot Clan appear in the film "Batman vs. Teenage Mutant Ninja Turtles" (which is based on the IDW crossover). Sato and Oshi (see above) are mentioned as founders of the Foot Clan. The Foot Clan collaborated with the League of Assassins in a plot that involved using a stolen Wayne Enterprises cloud seeder to spread a compound containing a mixture of mutagen and Joker venom on Gotham City. A select number of Foot Ninjas were mutated into mutant animals where two of them were mutated into a mutant pigeon and a mutant Tyrannosaurus.
