In "Requiem", he returns to New York City, far stronger and more vengeful than ever before. He shows up at the hideout where Karai is planning her next move with Shnigami and the Mighty Mutanimals. He defeats the Mutanimals effortlessly and badly injures Karai in the process. On the WOLF building, he faces off against Splinter, Slash, Raphael, April and Casey. He ultimately manages to murder Splinter and hurls him from the building to his death. He is then blasted by a tremendously powerful psychic wave from an enraged April, and is crushed by a garbage truck, though he again survives the onslaught.
