Shredder's Mansion is the next hideout for the Foot Clan somewhere in the woods of New York City after Shredder's injuries due to a fight with Splinter in episode 92 (season 4, episode 14) Earth's Last Stand, and after Karai took Shredder's previous hideout. After the fight with him and Splinter, he was severely weakened and mutated himself with the help of Baxter Stockman in order to regain his strength. In doing so, he became the Super Shredder. This is where Super Shredder and the turtles fight for the final time on the rooftop.
