Oroku Saki is the younger brother of Oroku Nagi who had been killed by a fellow ninja Hamato Yoshi (the owner of Splinter, the Turtles' mentor) in a feud over a woman named Tang Shen resulting in Yoshi fleeing with Shen to the United States.
Angry at the death of his older brother, Saki joined the Foot Clan and trained to be a ninja. He quickly became one of their deadliest warriors and rose up the ranks and was chosen to lead the Foot's American branch. Operating in New York under the name of The Shredder, Saki used the opportunity to avenge his brother by killing Yoshi and Shen. Under Saki's leadership, the Foot participated in variety of criminal activities, including drug smuggling, arms running, and assassination.
Fifteen years later Saki was challenged by the Ninja Turtles, which were the result of an accident exposing four ordinary turtles to radioactive waste. They were trained by Yoshi's pet rat Splinter, who had also been mutated by the same substance, to avenge his former master. After a lengthy rooftop battle where Saki seemed to be winning, Leonardo managed to plunge his sword through Saki's torso. Defeated, he was offered the opportunity to commit seppuku (ritual suicide), but Shredder refused and detonated a thermite grenade, in an attempt to take them with him to his death. However, in the last second Donatello used his bo to knock Shredder off the building to his death.
The Shredder 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 on in the story "Return To New York" the turtles returned to settle the score with their enemies. Leonardo faced off against the Shredder alone, in which Saki revealed he was brought back to life by a technique using worms feeding on his body and recreating his cells to reform his body. In the battle, Leonardo decapitates Saki, finally killing him, and the four turtles burn his body at the Hudson River.
