With his supposed demise, the Foot Clan, the Purple Dragons and the New York Mafia clash with each other for control of New York City. Unknown to them, the Shredder had survived once more and was retrieved by his daughter Karai, now being placed in a stasis tube and healed by worms inside a secret medical facility of the Foot headquarters. During his recuperation, Karai assumes leadership of the Foot Clan and makes peace with the Turtles after they help her end the turf war. However, once the Shredder is fully recovered, he vows vengeance and breaks off the truce. By this point, Baxter Stockman had created the Foot Mechs, mainly in the form of armed ninja robots, but in versions of the U.S. President, the English Prime Minister and Splinter as well. The Shredder's plans were again thwarted when the Turtles, Splinter, and their unlikely ally, the Triceraton Zog, locate his barge hideout, leading to another confrontation with the Foot. Aboard the freighter, Donatello programs a bomb set to go off in 30 minutes. The Shredder is defeated again when Zog sacrifices himself by seizing him and jumping into a blazing fire, but Karai rescues him on a helicopter.
