Oroku Saki (clone) (Mirage)

Several months after the death of Oroku Saki, The Shredder, several members of the Foot, as well as the Shredder himself, would jump and beat Leonardo to the brink of death, and throw his body through the window of April's Second Time Around store. Shredder and the Foot would attack the TMNT, and with the help of Casey Jones, they managed to escape to his old farmhouse in Northampton. After months of recuperation, the TMNT returned to New York, and with the help of Zog, a Triceraton mentally confused due to breathing our Earth oxygen, they went to take down the Foot and the Shredder once and for all. During the fight, Zog gets hacked to death by 3 deformed "Mutant Shredder clones". The other Turtles would face them and be taken down one by one, leaving Leonardo to go ahead and face the "real" Shredder himself.

Shredder revealed that he was a worm clone of the original Shredder, but still harbored the hatred of the original. The Foot employed some sort of mystic worms that ate remains of the dead, and then grow into the form of what they ate. The malformed Shredder Elite were the first three experiments with the worms, and the Shredder now facing Leonardo was their fourth. Shredder and Leonardo fought it out and in the end, Leo would end up beheading him. Leonardo would then take Shredder's body and burn it. With the Shredder gone, chaos erupted in New York City among the leaderless Foot Clan.

In issues 3 and 4 of Tales of the Teenage Mutant Ninja Turtles Vol. 2, it is shown that a few weeks after Leonardo defeated the Shredder, a Foot Mystic would find the remains and use the worms again, the worms then went out to find a new body, but this time they'd also eat the remains of a shark. This shark monster considered himself the real Oroku Saki. Facing the Turtles, who defeated it, he realized he was just a clone and escaped, also eating the Foot Mystic. Sometime later, the monster returned in issue #33, however, and had the Foot kidnap Casey's adopted daughter Shadow to lure the Turtles into a trap. With the Turtles away this Shark/Worm/Shredder monster would face Splinter and Casey Jones.
