Oroku Saki (also known as The Shredder) is the deadly and nefarious leader of the Foot Clan, and Splinter and the Turtles' vengeful arch-nemesis (voiced by Kevin Michael Richardson), and takes on the role of one of the primary antagonists of the Nickelodeon Teenage Mutant Ninja Turtles 2012 Series/Incarnation.
In this version, The Shredder is coated in durable armor from head to toe. His spikes are bigger and bulkier, though his body is much thinner. He still has his signature shoulder, arm, and leg gauntlets. However, his hand claws are now merged with his arm gauntlets. Unlike most incarnations, this version of the Shredder has a horrid injury on the right side of his face. In Splinter's flashbacks, Oroku Saki had black hair and a completely natural face, but after a violent encounter with Hamato Yoshi, his face was burnt, presumably when Yoshi's house caught fire. He now suffers from severe burns and has lost his hair and the sight of his right eye, which is now blood red with a blue iris and a white pupil.
Long ago, Shredder was known as Oroku Saki and was really good friends with Hamato Yoshi (also known as Splinter). However, both men fell in love at the same time with the same woman, Tang Shen, which ended up sparking a bitter rivalry between the two. One day, Saki insulted Yoshi, calling him many things. Yoshi snapped back, and he struck him down. This turned their little rivalry into hatred for eachother. Eventually, Tang Shen married Yoshi and gave birth to his daughter, Miwa. One night, Saki, mad with jealousy and hatred, attacked Yoshi in his home, intending to kill him. The fight resulted in Splinter losing his wife, and Saki was left badly wounded and disfigured - but he managed to steal Miwa and then proceeded to raise her as his own daughter...
Cold, cunning, and the evil leader of the Foot Clan, The Shredder is more than willing to go to any lengths to destroy both the Turtles and their rat sensei, Splinter. With his big army and his shredding armor, there is little that The Shredder cannot do. Oroku incorrectly believes that his old friend, Splinter, 'took' Tang Shen away from him, and thus, his extremely revengeful spirit has caused him to become cruel and pitiless over something that is otherwise pointless (and he even took Splinter's daughter away to mold her in his own image -- and he even goes to the trouble of keeping Karai's true identity furtive for a very long time). He now has little connection to humanity. The Shredder fights with a cold-blooded attitude, showing little mercy to anyone...Though he finds himself in a city swarming with mutant creatures and invading aliens, Shredder initially viewed it all as nothing but a distraction from his ultimate goal: His vendetta against Hamato Yoshi. When his lieutenants, Bradford and Xever, are mutated into Dogpound and Fishface, he does not question it at all and he continues to use them in his plans to destroy the Turtles and their master - and he only takes an interest in The Kraang after he sees that their advanced technology could prove useful to him. His narrow-minded attitude and overwhelming obsession sometimes does put Shredder at odds with his "adoptive" daughter, Karai, who generally seems to expresses more concern about the strange happenings in the city than her father does. When she complains that "There's more to life than your little vendetta", Shredder becomes angry and rants that there is nothing more to his life.
The Shredder is notably strong for a man his age, likely because he had trained for years with Splinter before the two became sworn enemies. When Shredder fought the four Turtles in Episode 9, "The Gauntlet", he bested them with his armor and Ninjutsu skills, though he is shown not to be exactly invincible because each Turtle was able to score a hit on him. However, his armor provides him with great protection from ninja shurikens and various attacks, so he is essentially able to protect himself and face his opponent simultaneously during battle. His upper body is coated in nearly indestructible armor, and he is also equipped with extendable blades attached to his hand gauntlets that he can use to render enemies helpless, or he can use them as a threat while interrogating someone...or something. He is also shown to be quite nimble, intelligent, clever, and manipulative.
The Shredder's first appearance was in Rise of the Turtles, as Master Splinter explained to Leonardo about his first failure, trying to protect his family from his vengeful rival and old friend, Oroku Saki (AKA, The Shredder). Saki lashed at Hamato Yoshi (Splinter's original identity) in his home and caused it to burn to the ground. The debris collapsed and killed Yoshi's wife, Tang Shen, which infuriated Saki even more because of his love for her. He left Yoshi in his crumbling house, believing that Yoshi would eventually perish. However, in Japan, Saki (who has recently made a following of ninjas called The Foot) saw a televised news bulletin from America, which tells how 'Ninjas' were in New York. As the bulletin continued, he caught a glimpse of a shuriken with Yoshi's insignia. Now realizing the status of his 'old nemesis', Saki dons his helmet and leads the Foot to America, where he intends to visit an 'old friend'... Though he had no actual appearance in Turtle Temper, the Shredder's reason for hating Yoshi was explained to a grumpy Raphael by Splinter, who was explaining how careless decisions of anger could jeopardize the people around him. Since Tang Shen was in love with Yoshi, Saki was overcome with jealousy, so he approached the two one day, and pointed out many harsh and violent words at Yoshi, insulting him to the point of uncontrollable rage. Yoshi stopped Saki with a violent attack that left him limping away, and since that day, Yoshi and Saki's rivalry became a bond of hatred. Splinter never forgave himself for acting so careless. Losing his temper was the reason Oroku Saki destroyed his family, and his normal life. In New Friend, Old Enemy, Shredder appears before his greatest pupil, Chris Bradford, and alerts him to Hamato Yoshi still being among the living. So he assigns Bradford with the job of eliminating Yoshi and his disciples. However, he was required to work alongside Shredder's second ally, a "street rat" he broke out of prison named Xever. In Never Say Xever, Bradford returns to his master and reports his failure, AND that Yoshi's disciples were actually "man-sized" turtles. Disappointed by Bradford's failure, the Shredder decides to have him follow Xever instead, hoping that the outcome will be different. However, the results were the same, and the Shredder could not accept his minions' lack of victory. So he announces that he will deal with the Turtles himself . The Shredder's disappointment of his lackeys continues where it left off in episode 9, The Gauntlet. Shredder's pet dog, Hachiko, bites Bradford's hand, and the Shredder explains that the dog wasn't pleased with him, nor was his master. Shredder's words of disappointment towards Bradford and Xever were as painful as Hachiko's teeth, going so far as to telling his pupil that he shamed his master with his incompetence even after every lesson and secret he shared with him, and he then cursed Xever, wishing that he never released the hoodlum from prison. The Shredder's words burned inside Bradford's mind, making him want to finish the Turtles off even more. And when the Foot reported to him about the Turtles current location, he and Xever followed them, hoping to please their master by killing the Turtles once and for all. After Bradford and Xever were washed away by the Mutagen inside a bomb, the Turtles celebrated their victory over them, but were shocked to hear a booming voice..."Your skills are impressive...but they will NOT save you." The Shredder made his presence known, making it all the more obvious that he is there to kill them. They all attacked him one by one, but he easily batted them back. He was proven not to be invincible though, as they managed to get in a few good hits each (Donatello most notably), and Michelangelo managed to hang him by his arm with the use of his nunchaku, though not for more than a few seconds. After Shredder defeated Donatello, Raphael, and Michelangelo, he grabbed Leonardo and demanded to know Splinter's whereabouts, promising that if Leo complied, he would not die with suffering. Shockingly, Shredder released the Turtles' leader when he saw Xever and Bradford changed into mutant animals. Though Shredder was terrified (and it is implied that he was even concerned) by this new surprise, he still intended to interrogate the Turtles, but they were already gone. He roared at his loss and confusion... In Panic in the Sewers, Splinter has a nightmare about The Shredder killing the Turtles one by one, so the wary sensei takes matters into his own hands by training the Turtles further and restricting their right to leave the lair and play their games. Meanwhile, Shredder orders a mutated Bradford (whom Mikey dubs Dogpound, because of his new dog-like form) to take command of the Purple Dragons and a pair of Foot Ninjas, and locate a tanker truck of chlorosulfonic acid. After a few hours, Bradford reports how the Turtles defeated them with "go-karts and a water balloon." Before Bradford could make an excuse, The Shredder sliced off a part of his seemingly unbreakable spikes, indicating that Shredder is now tempted to kill his pupil if he fails him again. In Mousers Attack!, Bradford's mutated form proves useful to The Shredder as he reported the Purple Dragons agreement to increase the Foot Clan's cut to 80% with 'no complaints'. Xever (stuck in a tank of water, due to his fish form) yells out his frustrations about how useless he is in his current body. Bradford and Shredder agree with him, but The Shredder is quick to threaten Bradford for the price of another loss...his legs. However, Bradford is quick to change Shredder's mind. The feral hound brings over Baxter Stockman, whose creations, the Mousers, cost The Shredder his chance of finding the Turtles' base. Shredder, of course, blames the scientist, but he also finds a use for him and his talents at technology. So, he spares Stockman in exchange for the latter's services... In New Girl in Town, the Shredder is not pleased with Karai's failure in killing Leonardo and tells her that the next time she must finish him off or else. In The Alien Agenda, the Shredder's patience is wearing thin when Stockman failed in his attempt to build mechanical legs for Xever. When Karai came with information about the Kraang, Shredder dismissed it and told her to focus on her mission to destroy the Turtles and their master. When Karai brought a Kraang droid, which proved useful, the Shredder was pleased and wanted Karai to find out everything she can about the Kraang. In Baxter's Gambit, Shredder for the first time does not act out so much in this episode, but he gives Stockman permission to set out the trap.
In Enemy of My Enemy, Shredder appears once again. He ignores Karai's warning about the Kraang Invasion. He faces the Turtles once more, is saved twice by Karai, and manages to capture a Kraang. In Karai's Vendetta, The Shredder interrogates the captive Kraang. He threatens to kill the Kraang with one of his blades unless he tells him what he needs to know. The Kraang tells him that the reason they are trying to destroy the turtles is because they are protecting Kraang's target; April. Shredder then orders Karai to capture her. In Pulverizer Returns!, He decides to create an army of mutants. When the Turtles foil his plan, he decides it's time to form an alliance with the Kraang. In Operation: Break Out, at TCRI, Shredder tells the Kraang that The Newtralizer nearly interfered in the plan. However, the Kraang remarks that it didn't prevent Kirby from being taken (which was part of their plan to find the turtles' lair and April). Shredder then says that vengeance will soon be theirs. In Booyaka-Showdown, Part 1, Shredder abducts April O' Neil and forces Splinter to duel with him. Splinter later finds out that the April that Shredder "abducted" is just a hologram. When Shredder finds out that Splinter is now a rat, he laughs, saying that he is "a rat caught in his trap". In Booyaka-Showdown, Part 2, Splinter battles the Shredder at the Foot Clan's hideout. Shredder later reveals sometime into the battle that Karai is in fact Miwa: Splinter's supposedly dead daughter. During the battle, Splinter, in a new flurry of rage, knocks off Shredder's helmet, to reveal the latter's horribly burned face, and moved in for the finishing blow. This was prevented by Karai, however. Shredder informs Karai that the rat is Hamato Yoshi, the man that he had told her had killed his mother, which happens to be another lie fed to her by her false father. In The Mutation Situation, Shredder can be seen in his lair, aproving The Kraang's plan of creating an ape-like creature to attack the turtles. However, after The Kraang's plan fails, Shredder informs Karai that since the aliens are of no use to him now, he will begin to develop an army on his own. In Follow The Leader, Shredder tests his new robotic foot soldiers built by the Kraang (which indicates that the Kraang are still in fact still useful to him, and their alliance still stands) by having them fight Karai. He then leaves for Japan to take care of an "urgent matter", while he tells Karai not to make any move on the turtles while he is gone.
- Hamato Yoshi / Splinter - A while before the series began, he and Splinter were good friends. They lived in Japan where they learned the art of Ninjitsu. However, they suffered a great strain when they both fell in love with the very same woman, Tang Shen. They competed for her attention, but she chose Splinter in the end. Jealous, he began harassing Splinter, insulting him and purposely trying to get him angry. This eventually culminated in The Shredder breaking into Splinter's house and challenging him to a duel. Both men engaged in battle, and the house soon caught fire in the process (due to the fact that some burning candles were laying around), killing Tang Shen and horridly burning the Shredder's face. The latter found Miwa and took her in, raising her as his own daughter and telling her lies about what Hamato Yoshi "did". Sixteen years later, The Shredder discovers that Splinter is hiding in New York, and he leaves Japan (along with his deployed Foot Ninja) to finish him off. The two finally meet again in "Booyaka-Showdown, Part 2" and duel with eachother in The Foot Headquarters. The Shredder reveals to Splinter that his daughter is indeed alive, and he attempts to have her kill Splinter when she shows up. With this revelation, it is likely that Hamato despises The Shredder even more than he formerly did.
- The Turtles - Since they are affiliated with Splinter (as his disciples), Shredder views the turtles as enemies, and he orders his henchmen to find and kill them throughout the entire series. However, out of the two times that The Shredder has encountered them, he's let them live for the purpose of interrogating them (which hasn't yet happened).
- April O'Neil - The Shredder uses April as bait to lure his sworn enemy, Splinter, out of hiding. Due to this, it is quite probable that April dislikes him greatly.
- Chris Bradford/Dogpound/Rahzar - Known as Shredder's top lieutenant and was formerly known as the Foot's second best fighter before mutating into Dogpound, but he still maintained his rank and his respect to the clan.
- Xever/Fishface - Works for The Shredder after being freed from a prison and being hired by him, which Shredder did mainly because he found Xever's skills useful, as well as the fact that Xever "likes having a job where he gets to crack skulls everyday".
- Karai - Splinter's daughter, Miwa, who Shredder kidnapped after the events of his and Hamato Yoshi's final battle, named her Karai, and raised her as his own child.
- The Kraang - An alliance made only to get closer to Hamato Yoshi.
- Baxter Stockman - Shredder spared Stockman because the man is a talented inventor, and very useful to his clan, which led to several improvements, such as making Fishface a pair of robotic legs, thus making the latter a more powerful combatant. The Shredder, however, for the most part, cares little for Stockman and he probably chose to dislike him even more after the scientist trapped Dogpound and Fishface in the "Maze of Doom".
- Tang Shen - A woman that both Oroku Saki and Hamato Yoshi fell in love with. She chose Yoshi over Saki, however, and in a fit of jealousy and rage, he attacked Yoshi one night and killed Tang Shen in the process.
