Shredder (Batman vs. TMNT)

"I promised you would die if you stood in my way. You are no match for me. Now I will take control of the League of Assassins, harness the power of the Lazarus Pits, and the Foot Clan will rule for a thousand years!"

- Shredder to the Batman

Oroku Saki, known also as Shredder, is the nemesis of the Ninja Turtles, the leader of the Foot Clan, and one of the two main antagonists along with Ra's Al Ghul in the film Batman vs. Teenage Mutant Ninja Turtles.

He was voiced by Andrew Kishino, who also voiced Shang Tsung and Sektor in Mortal Kombat 9 and Janja.

History
Shredder allies his forces with Ra's Al Ghul and the League of Assassins to build a machine designed to transform Gotham's citizens into unhinged mutants.

In exchange for his assistance, Ra's promises Shredder access to one of his Lazarus Pits, which would grant him eternal life. When he and the Foot Clan try to steal a cloud seeder from Wayne Enterprises, he ends up fighting Batman and barely comes out victorious after using an ancient technique.

Later, he fights Batman once more when the Turtles and the Bat Family arrive at Ace Chemicals to stop him and Ra's from activating the machine. Though he gains the upper hand on the Dark Knight once again, he is thrown off when Batman says "Cowabunga" and gains assistance from Raphael.

After Michaelangelo and Donatello destroy the machine, the debris sends him into a vat of chemicals as the plant explodes. In the post-credits scene, he is revealed to have survived the explosion and now strongly resembles the Joker.

Trivia

 * The claw marks on Shredder's face are presumably a homage to the 1990 movie, in which Splinter's attack had left scars on his enemy's cheek. However, the origins of these scars are not explored in the crossover.
 * His appearance overall is a blending of his 1990 film (clothing and scars) and 1987 series counterparts (helmet design and cape).
