During this time, they are presumed dead, but Saki orders Baxter Stockman to find evidence that the Turtles died, and is cheated by Stockman into believing so. When Leonardo is completely healed from his injuries, the Turtles and Splinter return to New York to face the Shredder once more. They launch a surprise assault on the Foot headquarters, fighting their way through Shredder's minions and eventually reaching his throne. By the end of the battle, Leonardo decapitates the Shredder when they strike each other in one final clash. Not knowing that he is an Utrom, the Turtles believe him to be finally killed for good. After they leave, the Shredder is seen to be getting up and walking away carrying his severed head.
