However, it was not yet the end of the Shredder. He returned on Christmas Eve seemingly resurrected with an army of Foot Ninjas severely beating Leonardo and burning down the apartment of the turtles' ally April O'Neil, forcing them to go into hiding outside the city. A year later, in the story "Return to New York", the Turtles returned to settle the score with the Shredder. Leonardo faced off against Oroku Saki alone, during which Saki revealed he was brought back to life by a technique using worms feeding on his remains and recreating his cells to reform his body. In the battle, Leonardo decapitates the villain, finally killing him, and the four turtles burn his body at the Hudson River.
