Ernie Reyes Jr.

Framed for assassinating the Grandmaster, the Lost Ninja Clan must battle their way up an underground nuclear bunker filled with hordes of supernatural enemies, mutants and flesh eating zombies. Trapped 200 feet below the earth's crust, these ninjas will face hell.

The turtles find out where the Ooze, the substance which made them mutate, came from. Unfortunately Shredder learns about it too, and uses it to enhance himself. So the turtles have to prove again who's the better ninja fighter.
