The Shredder

"So, my old enemy is in New York and training his own army. At last I can finish what I started so long ago. Prepare my jet! I'm going to visit an old friend."
— Shredder's first line

**Oroku Saki** (also known as the **Shredder**) was the deadly and nefarious leader of the Foot Clan, and Splinter and the Ninja Turtles' vengeful arch-nemesis (voiced by Kevin Michael Richardson), and takes on the role of one of the central antagonists of the Nickelodeon Teenage Mutant Ninja Turtles 2012 Series.

## Appearance

The Shredder is a slim, but tall, muscular and toned Japanese man with shiny, chrome plate armor on his chest, shoulders, arms and lower legs, worn over a maroon outfit with a dark blue cape hanging over his back. His signature helmet, the Kuro Kabuto, is perhaps the most notable aspect of his appearance and it masks a face that is partially burned and disfigured, such to the extent that he has very little vision left in his right eye.

Unlike previous incarnations of the Shredder who held tekko-kagi in their hands, this version uses customized, partially mechanical ones built into his gauntlets. His armor is also larger and bulkier than previous versions, except perhaps Ch'rell, though it's streamlined and smooth at the same time. The spikes on it are larger, longer and more blade-like than most previous versions (though once again bearing some similarities to Ch'rell's). As previously stated this Shredder suffers a serious, disfiguring burn on the right side of his face; a considerably greater injury than the scratch marks (from Splinter) most others possess that leaves him nearly, or completely, blind in that eye.

Upon becoming the Super Shredder, Saki's body underwent hideous disfigurement. His eyes now glow green and his teeth are always visible on the side. His body has become more muscular with metal blades sticking out of almost every part of his body, as well as visible veins of mutagen connecting to what appears to be his heart at the center of his chest. His helmet has also fused with head; its own blades becoming longer and spikier and its frontal mask resembling a human skull's face. The only clothing he wears now are his tattered pants, bandages wrapped around his clawed feet and a torn up cape.

## Background

Oroku Saki was born in rural Japan into the ninja Foot Clan, the longtime enemies of the Hamato Clan. After a particularly devastating assault by the Hamato Clan on a Foot Clan village that left the rival ninja clan in tatters, the baby Oroku Saki was discovered amongst the wreckage by Hamato Yoshi's father. He was then raised alongside Yoshi as brothers; best of friends and greatest of rivals, with Oroku blissfully unaware of his true heritage.

Their rivalry escalated when they met Tang Shen and subsequently fell in love with her. Their bids for her affection turned their rivalry into hatred and Oroku Saki insulted Hamato Yoshi in front of Tang Shen, and in response was attacked by Yoshi. This brief fight ended in victory for Yoshi, while Saki fled and wandered alone. During this time Saki learned of his true heritage and rebuilt the Foot Clan and donned the moniker 'Shredder'.

Sometime after this he discovered Tang Shen's marriage to Hamato Yoshi and attacked their home. During the fight that broke out Tang Shen was accidentally killed by Saki's hand and the house burnt to the ground. Saki also discovered the existence of Hamato Yoshi's infant daughter during this assault, and when the fire forced Saki to flee and leave an injured Yoshi to die, he took the baby with him. He later claimed that he was 'returning the favor' to Yoshi for having Tang Shen 'stolen' from him. Shredder would go on to raise the baby as his own daughter, naming her Karai and raising her to hate her true father.

After the fight with Yoshi, Shredder found the ancient Kuro Kabuto worn by Foot Clan leaders in the past, and proceeded to fully transform the Foot Clan into a worldwide crime syndicate. He also freed the Brazilian street thug Xever from prison and took on martial artist celebrity Chris Bradford as an apprentice; though it's not particularly clear when this latter event took place.

## Personality

Cold, cunning, and extremely ruthless, the Shredder is a man of pure evil who has allowed his hatred to utterly consume his humanity. His massive army of ninja enforcers, his vast wealth and influential connections (such as Steranko), and his absolute mastery of martial arts, coupled with his bladed armor, make him a very powerful and dangerous force to be reckoned with. He will go to any lengths to achieve his goals, even as far as forging a business-like alliance with the alien Kraang who wishes only to see humanity wiped out or enslaved. But even more so, he was willing to let the Triceratons destroy the whole planet Earth, including himself in the process, just so he could strike down Splinter right before he could stop their doomsday device.

The Shredder's immense capacity for hatred seems to stem from an inability to accept his own failures and bad luck as just misfortune and mistakes. Instead he seems to need someone to blame everything on; shown when he blames Splinter for Tang Shen's death, despite being the one who initiated the assault that took her life, and blaming him again for Karai's mutation, despite having put the girl in danger in the first place. Saki is utterly convinced that Splinter is the cause for all suffering and misfortune he endures, and considers anyone linked to Splinter to be just as guilty. And he believes that anyone who has contributed to his misfortunes should pay with their lives.

Not only is the Shredder an extremely spiteful and vindictive individual, but also an extremely obsessive one. So obsessed with his hatreds and vendettas is he that upon being told there is more to life than his vengeance, he became angry and stated that there is nothing. He will hunt his targets to the ends of the Earth to claim their lives, and will not stop until this has happened.

Yet despite his burning hatred, he is able to maintain a very calm and calculated persona most of the time, and is a master commander, but is extremely arrogant. This arrogance leads him to refuse to confront the Turtles personally, despite wishing their deaths, and he seems to consider only Splinter worthy of facing in combat, leaving all others to his minions and only fighting them if he deems it necessary.

But, despite his intense hatred, the Shredder has truly come to care and love Karai as his own daughter, as shown with his desire for her to understand his actions and by how distraught he was when she was mutated. He also had no intention of harming her and even stopped Tiger Claw from finishing her. However, the Shredder is still blinded by his burning hatred and refuses to take responsibility for the harm Karai has endured because of him. Later, the Shredder is shown remembering Karai's past training and mutation and when striking a dangerous deal with the Kraang, he states that he will only help them if they help him gain his revenge and return Karai to normal. However, it is debatable whether his love for Karai is genuine or part of his desire to get revenge on Splinter and keep Karai for himself, as seen when he is willing to take away her free will by using the brain worm on her.

However, despite his love for Karai, its apparent he cares far more about his vendetta with Splinter then his adopted daughter's well-being. This is shown when Shredder kills Splinter before he can shut off the Heart of Darkness, despite knowing him, and the rest of the world, including Karai will die if it isn't stopped.

As shown in The Super Shredder, after mutating, Oroko Saki's sanity slipped greatly, becoming even more single-mindedly obsessed with destroying Splinter. He began to believe his own false story he told Karai; that he was truly her biological father and that Yoshi was the one who attacked him and Tang-Shen. He also ignored Tiger-Claw's well meaning pleas to stop taking Mutagen, as Super Shredder was more interested in undoing his damaged hand.

## Abilities

The Shredder is extremely strong and agile from decades of training in martial arts. These many years spent perfecting his skills have left as an almost unparalleled master of martial arts with only Splinter standing as an equal to him. His skills are so great that not even all four turtles together were able to do much more than be a nuisance to him in combat; though each turtle was able to strike him once, their strikes caused little injury and had no lasting effect. The Shredder's strikes on the Turtles, however, left them severely injured for weeks. His skills are great enough that even the mutants under his command respect and fear him; including the vicious Tiger Claw. In a recent fight he showed himself capable of fighting off both the Turtles *and* the Mutanimals with little difficulty.

The Shredder's awe-inspiring fighting skills are only maximized further by the nigh indestructible bladed armor he wears, complete with customized and slightly mechanical bagh naka with extendable claws and a third katar-like blade that is concealed between the two claws. These blades are so strong and sharp that they can cut shipping containers and the spikes that protruded from Dogpound's shoulder. In addition the blades create an extremely intimidating silhouette for the purposes of psychological combat. The end result is that Shredder can both defend and attack at the same time, making his whole body both a shield and a sword.

Yet perhaps just as potent as his physical abilities are the Shredder's cruel intellect and skillful business mind. In approximately fifteen years he was able to transform the Foot Clan from a dying, scattered ninja clan in rural Japan into a powerful global crime syndicate. He was even able to strike a business-like alliance with the Kraang, despite their overall disdain for anything not one of them.

As the Super Shredder, Saki still retains his original ninja skills as well as powerful new mutant abilities, making him a force more deadly than any other the turtles have dealt with prior:

* **Mutated Steel/Bone Armor:** Super Shredder's armor was shown to take little to no damage from a combined assault from Karai's mutant form and Shinigami.
* **Superhuman Strength:** Super Shredder is shown to be able to lift and toss a charging Shellraiser, as well as overpowering the likes of both Leatherhead and Slash simultaneously in battle.
* **Nigh-Invulnerability:** Following his super mutagen power enhancement, Shredder's body became invulnerable to virtually all forms of physical damage. He is also invulnerable to extreme heat sources such as fire and super-heated plasma blasts (which weren't even enough to burn through his cape).
* **Steel/Bone Blades:** One of Super Shredder's most noteworthy powers is his serrated blade protruding out of his body. Similarly to his bagh naka, he can create two out of his arms, longer than his mechanical ones. He can also rapidly fire them as projectiles and regrow them just as fast.
* **Enhanced Senses:** Shredder's sense of smell and hearing has also greatly improved, allowing him to track Splinter as he was hiding.
* **Immunity to Retro-Mutagen:** Due to the super mutagen stabilizing his form, Super Shredder is a special mutant who cannot be cured.

Despite these enhancements, this new form's initial main weakness was that his mutagen engorged heart is left exposed, and if struck he will expel mutagen from with-in causing his form to become unstable. However, thanks to the super mutagen enhancement from Baxter Stockman stabilizing his form, this flaw was later eliminated, as the exposed heart became so durable that not even Karai's Wakizashi could pierce it, and instead even shattered when it made contact.

## History

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 out at Hamato Yoshi (Splinter's original identity) in his home. During the ensuring chaos, Hamato's house is lit on fire and Yoshi's wife, Tang Shen, is killed by the Shredder's blind rage. After a long fight, Saki leaves Yoshi for dead in the burning house, believing that Yoshi would eventually perish. However this was not the case. In Japan, Saki (who has of recently formed a clan of ninjas called The Foot) saw a television news bulletin from America in which it shows how 'Ninjas' are operating 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 his, '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 cursed 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 that Saki destroyed his family and his normal life.

In New Friend, Old Enemy, the Shredder appears before his greatest pupil, Chris Bradford, and alerts him to Hamato Yoshi still being among the living. The Shredder assigns Bradford with the job of eliminating Yoshi and his disciples. However, he was required to work alongside the Shredder's second ally, a "street rat" by the name of 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's orders instead, hoping that the outcome will be more different. However, the results were still the same and Shredder could not accept his minions' lack of victory. Because of this, 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. The 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 once and for all. 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 for good. After their loss, Bradford and Xever were washed away by the mutagen inside a bomb that Bradford cut into. 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. The Turtles all attacked him one by one, but Shredder easily held them off. He was proven not to be invincible though, as they managed to get in a few good hits off (Donatello most notably). Michelangelo managed to hang the Shredder by his arm with the use of his nunchaku, though not for more than a few seconds. After the Shredder defeated Donatello, Raphael, and Michelangelo, he grabbed Leonardo by the neck and demanded to know Splinter's whereabouts, promising that if Leo complied, he would not die with suffering. Shockingly, the Shredder released the Turtles' leader when he saw Xever and Bradford changed into mutant animals. Though the 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, the 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 to flood the Turtles' sewer home with. 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 the Shredder agree with him, but the Foot leader is quick to threaten Bradford for the price of another loss...his legs. However, Bradford is quick to change the Shredder's mind. The feral hound brings over Baxter Stockman, whose creations, the Mousers, cost the Shredder his chance of finding the Turtles' base. Of course, the Shredder blames the engineer, 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, the 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, the 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, the 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 the Kraang's target; April. The Shredder then orders Karai to capture her.

In The Pulverizer Returns, he decides to obtain mutagen from the Kraang so that he can transform some of the Foot Soldiers into mutants, though warned by the captive Kraang operative of unpredictable results. After the Turtles thwart the plot, the captive Kraang operative tells Shredder that they have a common enemy in the Turtles and thus an alliance was born.

In Operation: Break Out, at TCRI, the 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.

Showdown, Part 1, the Shredder abducts April O' Neil and forces Splinter to duel with him. Splinter later finds out that the April that the Shredder "abducted" is just a hologram. When the Shredder finds out that Splinter is now a rat, he laughs, saying that he is "a rat caught in his trap." He then reveals that he only need April as bait to lure him out and now that he had, he had no use of April so he handed her over to the Kraang.

In Showdown, Part 2, Splinter battles the Shredder at the Foot Clan's hideout. The 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 the Shredder's helmet, to reveal the latter's horribly burned face, and moved in for the finishing blow. This was prevented by Karai, however. The 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. As Karai attacks her real father, Shredder chuckles maliciously at how Splinter has to fight his own daughter.

In The Mutation Situation, the Shredder can be seen in his lair, approving the Kraang's plan of creating an ape-like creature to attack the turtles. However, after the Kraang's plan fails, the 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, the 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.

In Target: April O'Neil, He speaks to Karai through a mouser projection screen [for he's still in Japan]. He is very angry at her for disobeying him and his orders after she went after the Turtles and failed miserably. Karai states that the Kraang have made improvements to the Foot-Bots which she blames for the Turtles' escape. The Shredder then cuts her off and orders her to not have any more dealings with the Kraang until he returns. He then threatens to her punish her should she disobey him again and he assures her the consequences will be severe. He then signs off.

In The Manhattan Project, the Shredder brings Tiger Claw onto his team and makes him his second-in-command. Karai is appalled by this, saying that she earned this position fair and square. The Shredder then sends Tiger Claw off to find & abduct Splinter and the Turtles, commanding Karai to follow Tiger Claw's every order. After the capture of Splinter, Shredder enters the lair, along with Karai. He tells both Xever and Bradford that they must leave the area for the time being. Afterward, he immediately approaches Splinter and purposely tries to exacerbate things by telling him that he has grown to be 'a wretched rat-man only waiting to be put out of his misery'. Splinter retorts that, at least he is not someone who wears a mask, hiding the low amount of humanity that they have left. Shredder says that Splinter is the one and only reason that he wears his signature helmet. The Shredder then extends one of his gauntlets and prepares to kill his mortal enemy. However, Karai halts his horrible action. The Shredder asks why she would dare to try and stop him, to which Karai replies that executing a sworn enemy while the latter is poisoned and chained is just improper. She then recommends allowing Splinter to perish with the slightest bit of honor and in a combat situation, preferably. Tiger Claw ends up siding with Karai on this one. Thus, the Shredder offers Splinter one last chance to inhale and exhale before fighting with him. Meanwhile, Leo is climbing up the side of the Foot Headquarters with the usage of Tegaki. After destroying a couple Foot-Bots that were put on guard, he successfully gains entry into the building and jumps down several platforms until he has reached his sensei. However, the throne room is then lit up with dozens of orange lights at the sidelines, and this is when the Shredder appears from behind his throne. Just when Leo is about to pull out his twin weapons, Tiger Claw (along with the two other Mutants and Stockman) appears and twists his arm, disarming him and knocking him onto the floor. The Shredder then asks where the other three Turtles are, but Tiger Claw, using his very keen sense of smell, says that he senses no one else in the area. The Shredder then removes his cape, breaks the bindings around Splinter's arms, and instructs Leo to watch in horror as the retribution with Splinter is finally carried out to the end. In spite of being poisoned, Splinter is actually able to avoid just a few of the Shredder's attacks, but Yoshi is then kicked hard in the torso, sending him flying a good length of the way across the room. Shredder then picks him up and is about to put him out of his misery for certain when yet another earthquake occurs, catching the Shredder and his henchman off-guard. Not only that - but our heroes then enter, armed with some handy fire crackers, which they actually use to distract the villains' attention and escape with their sensei.

In The Lonely Mutation Of Baxter Stockman, the Shredder and Rahzar walk in, scolding Stockman for creating a bunch of useless mutants, including a duck. Stockman explains that it swims, flies, and knows tae kwon do, but this is obviously not enough to please the Shredder. Stockman then says that he has devised plans for pigs and rhinos, but this still does not get himself off the hook. The Shredder knows that Stockman has failed him one time too many, and Rahzar begins approaching the engineer with the intention of severely harming him, but the Shredder has a much more suitable fate in mind - mutating Stockman. Shredder presses a button on the controller that triggers the bottles on Stockman's neck brace to crack, slowly spewing the contained ooze all over him. The Shredder and Rahzar then leave him behind to mutate. The Foot-Bots drag a dazed Stockman-Fly all the way back to the Foot HQ. They then pause and Rahzar approaches. He says that he wants to squish Stockman here and now, but the Shredder has "other plans." Shredder then says that Stockman will need to create one last mutant to be evaluated -- and if he messes up, the villain will pluck his wings. Knowing that his hateful life will continue from this point, Stockman-Fly thanks the Shredder for his 'generosity,' while Rahzar tosses a chocolate bar for Stockman-Fly to eat.

In The Wrath of Tiger Claw, the Shredder sees Karai looking at a photo of her mother and asks what troubles her. Karai asks him to tell her the truth about Hamato Yoshi, the Shredder tells her that he is responsible for the death of her mother just as Tiger Claw enters the room. Tiger Claw explains how he crossed different dimensions to return so he could have is revenge against all those who have wronged him. The Shredder tells Tiger Claw to go after the Turtles and and destroy them despite Karai's objections, he orders her to go with him. Tiger Claw brings Karai before the Shredder, telling him of her betrayal. Karai demands that he tell her the truth about Splinter to which the Shredder finally admits that she is Yoshi's daughter. The Shredder then tells Tiger Claw to take her away, locking her away in a cell.

In The Legend of the Kuro Kabuto, the Shredder visits Karai in her jail cell explaining why he kept her real father a secret and hopes that she will one day understand what he had to do. After the Shredder's helmet called the Kuro Kabuto is stolen by Anton Zeck on Steranko's behalf, the Shredder finds his calling card on a glued-down Rahzar and orders him to get him everyone. After explaining the history of the Kuro Kabuto, The Shredder orders his minions to hunt for Anton Zeck where Fishface is sent with Stockman-Fly while Rahzar is sent with Tiger Claw. When Leonardo confronts the Shredder for a trade, he kept him busy long enough for the others to get to Karai. The Shredder managed to get the Kuro Kabuto back upon the Turtles' retreat. It later turned out to be a bomb as the Turtles evade it.

In Vengeance is Mine, the Shredder appears and orders Tiger Claw to spare Karai's life. Tiger Claw agrees and, later, Karai awakens with chains around both of her wrists, while Shredder is standing behind her. The Shredder takes off the lower part of his mask and asks why Karai has insisted on trying to hurt him. Karai refuses to speak, causing the Shredder to ask why 'his daughter' does not have a thing to say. Karai harshly scolds him and, at the top of her lungs, yells that she is not his daughter. As Karai escapes, she looks up to see the Shredder staring down at her from the top of the building with an enraged look in his eyes. Tiger Claw reports back to the Shredder, stating that he has searched the city in search of Karai and that he has ordered some Foot Bots to continue the search and to return with every detail. After Tiger Claw reveals that he has not had any luck yet, the Shredder tells his minion that his efforts are pointless and that Karai's escape was to be counted on. He then goes on to say that Karai will most likely arrive with Splinter and his pupils to finish what they have started, which will allow the Shredder to have his vengeance. Shredder then commands Tiger Claw to inform Stockman of the situation. Breaking back into the Shredder's headquarters, Karai notices that her former 'father' seems to be resting in his throne, but, after coming closer, it is then revealed that the Shredder has put Chrome Dome there instead. She is then nearly captured by the robot, but manages to stab it through the chest before it can possibly inflict any harm. Shredder then emerges from the shadows and says that she has returned sooner than expected. She then confronts Shredder in combat, vowing to give him a final goodbye. However, Shredder quickly tells her that the mistake she's made is foolish and that he has taught her everything she has come to learn. Shredder then brings his blade up close to her neck and has her handed over to a massive hoard of his own henchmen. Karai is then taken away so that a mysterious experiment can begin.Inside Baxter's new lab, Shredder walks in and it is soon revealed that Baxter was told to extract a large portion of DNA from a serpent and place it inside of his vat filled with Mutagen. Shredder then orders his men to have Karai bound to a table within a cage hanging over the vat. Tiger Claw remarks that Shredder is pretty ruthless if he's wanting to mutate his own 'cub', but Shredder replies that Karai becoming a mutant is not his actual intentions. His plan is that, when the Turtles attempt to save Karai, he will drop them into the mutagen, and this will cause them to become brainless serpents that will immediately start to target Splinter. Therefore, the latter would be left mortified and this is when Shredder would get the chance to 'shatter' his body. However, what Baxter did not reveal is that, the split second before Shredder entered, a different substance was accidentally spilled into the jar that is containing the modified Mutagen. Regardless, he states that everything has been prepared perfectly. During the next moment, Splinter and his sons all jump down from the ceiling. It is not that long before Donnie, Mikey, and Raph are all trapped inside of spring-loaded cages that were set on the floor, while Master Splinter is restrained by ropes thrown onto him by the Foot-Bots. Leo is also tossed into a cage by a Foot-Bot, but, luckily, just as the cage detracts, he slips a part of his Katana into an opening and this lets him pry his way out. He then jumps up and over the vat in order to reach Karai. He removes the gag from her mouth and she thanks him. However, Shredder then tries to stab Leo from behind, but Leo ducks and Shredder's gauntlet accidentally cuts through the chain that is holding up Karai's cage. Leo and Shredder both jump clear of the vat, but Karai's cage drops, and sinks deep into the mutagen, as Master Splinter observes this in sadness, while Shredder is horrified by his missed attack on Leo sending Karai into the mutagen by mistake. As a now mutant serpent Karai makes her way out of the mutagen, Shredder is filled with remorse. However, refusing to accept the blame for what happened, Shredder immediately tries to pin the blame on Splinter for Karai's mutation, and he charges off to finish his foe, only to be stopped when a large piece of the ceiling caves in and prevents him from continuing further. Tiger Claw says to Shredder that they have won this fight and should retreat proudly. Shredder is angry when he hears these words, as he does not feel like he has won at all and vows to avenge Karai, before disappearing into the debris.

In The Invasion Shredder is seated on his throne, remembering Karai as a human and his pride in her skills as a ninja. Tiger Claw then enters the room, asking the Shredder if he's made up his mind about a deal with the Kraang. The Shredder states that he does accept their alliance with the Kraang, as they have provided the Foot Clan with alot of Technology and have asked for little in return. Tiger Claw questions the Shredder's decision because the Kraang will most likely betray him, as they have no care for the human race. The Shredder states that he has no regard for it, either. Kraang Prime then contacts the Shredder, asking for a decision as well. In exchange for the Kraang to reverse Karai's mutation and 'deliver' Splinter and the Turtles to the Shredder, the Shredder will then help the Kraang take over New York and the world. As chaos erupts during the Kraang invasion, watches it with his disciples. He gets word that Leonardo is moving in their direction. The Shredder prepares an ambush for him. Leo battles the Shredder's Foot-Bots. He demands the Shredder to face him, but the Shredder denies this, stating that Leo is beneath his abilities. Leo begins to tire from the Foot-Bots' attacks, but the Foot do not let up. Tiger Claw asks the Shredder if he can finish Leo off and the Shredder tells him not to do it yet, as he wants to see Leo suffer.Leo fights off more Foot-Bots at the construction site and loses both his katana in the process. When his enemies seem to be defeated, Leo pauses, but a Foot-Bot on the ground grabs his leg and Leo loses balance, causing him to roll down the embankment and into the ice water collected in the pit below him. Leo soon comes out of the water, chilled and exhausted, but is unwilling to flee from his enemies. The Shredder then gives Tiger Claw, Xever and Rahzar the go-ahead to attack Leonardo, and they do so. Leo fights them off and, amazingly, he defeats all of them, but the Shredder then slashes him across the chest, causing Leo to fall completely unconscious. Tiger Claw picks up the battered and senseless Leo and looks at his T-Phone, seeing the text messages from Mikey telling Leo to come to April's home. The Shredder demands his minions to draw every one in the apartment out by throwing in Leo. As Tiger Claw and the others leave to do this, the Shredder is confronted by Splinter, who demands to know where Leo is. The Shredder states that he has 'taken' Leonardo much like he took Miwa from Splinter and then they Fight.the Shredder states that Splinter is weak, while the Shredder is still strong with his rage. After Splinter knocks down the Shredder, however, Splinter tells him that anger is something that doesn't last. The Shredder ignores Splinter's wisdom and kicks him against a machine, causing lead pipes to fall on top of him. As the Shredder is poised to drive his gauntlets between Splinter's eyes, Leatherhead leaps on top of the Shredder and grabs him inside of his jaws, trying to crush him. However, the Shredder also defeats him and kicks him down into the water at the bottom of the pit. Now, full of righteous anger, Splinter starts to battle the Shredder with newfound strength and they both fall into the pit after Leatherhead. Splinter and the Shredder continue to fight in the sewer, April, Donnie, Mikey and Raph follow April's vision to the end of at drain pipe where they are trapped behind bars and only able to watch and shout words of encouragement to Splinter as he fights with the Shredder. Although Splinter is able to send his enemy flying through a wall, the Shredder strikes him down and turns a nearby wheel, activating a whirlpool that he throws Splinter into. This enrages Raph beyond words. The Shredder then leaves and Raph is angry beyond words, calling the Shredder a monster.

In "Vision Quest", he appears in the spirit realm as Leonardo's opponent. At first, he overwhelms him by attacking the injured leg and being able to snatch the twin katanas welded. Leo is nearly defeated until he realizes the pain is all in his mind, leading to him to finally take the Shredder on. Shredder then grows to a giant size and is able to grab Leo, but is defeated upon Leo escaping his clutches and shooting him with an arrow to his burnt eye. Following this victory, Leo states that one day he'll beat him in the real world.

In "Return to New York", he warns Tiger Claw to watch his tone, and reveals he knows much more about the Kraang's plan. For some reason, Shredder had other plans. He decides to destroy the Kraang and take over the city himself when the time is right. While telling Tiger Claw to continue his search for Karai, the Foot-Bots arrived in with Splinter (who's lost his mind from the injuries). He has Stockman-Fly to place him in a containment unit to have his memories restored. Later, when Mikey accidentally sets that alarm on, Shredder and his gang arrive in to see the Turtles, Casey and April with Splinter, who's mind has been restored. Shredder has his clan to go after them, but they quickly get out with the help of ninja smoke bombs.

In "Serpent Hunt" Shredder has Fishface and Rahzar continue their search for Karai. At the docks, he discovers Zeck was employed Steranko to steal his helmet, but Steranko arrives with a restrained Karai, who he promises to get back to Shredder in exchange for a way out of the city safely. After Karai and the Turtles escape, Shredder becomes furious at Zeck and Steranko for attempting to steal his helmet and hunting Karai, and proceeds to have them both mutated in Stockman-Fly's lab, despite Steranko's pleads for forgiveness, since they've known each other for about 10 years. When Stockman-Fly adds warthog DNA in the first batch of mutagen, Shredder orders Fishface to have Zeck to be mutated first for stealing the Kuro Kabuto. After Zeck is mutated, Shredder then has Stockman-Fly add rhinoceros DNA in the second mutagen batch to have Steranko mutated for his betrayal. He tells Steranko that his animal (the rhinoceros) is apropos. Steranko still tries to convince Shredder he would be better for him as a human, but Shredder, still ignoring his pleads, nods at Rahzar, who kicks Steranko in the second mutagen batch.

In "The Pig and The Rhino" Zeck and Steranko attack Shredder for mutating them but he easily defeats them and makes them his new servants. He orders them to find Karai again or else he will further injure them. Despite the two (whom Mikey calls Bebop and Rocksteady) originally disobeying him to go after the Turtles, they end up capturing Karai and bring her to his lair. Shredder vows to cure Karai and have his revenge on the Turtles.

He  appears in "Casey Jones vs. the Underworld "  were he watches Karai in Stokman's Lab.Shredder Then meets with  Don Vizioso , an Italian crime lord. After mentioning how he controls the Russian Mob through Rocksteady, the Purple Dragons through Hun , and the South American gangs through Fishface, Shredder proves his point by slicing his meatballs and candles, Vizioso swears his allegiance with Shredder. Hun then brings him the chemicals he was looking for. After Stockman-Fly told Shredder they did not have the proper equipment they needed Hun gave Shredder access to the abandoned Auman Chemicals (where the chemicals were obtained from) on the Purple Dragons' turf in exchange for being put in charge of the facility. After the Turtles and Casey Jones toss an additive into a chemical vat which causes a chain reaction, he says that they have only delayed his plans and orders his henchmen to clean up the factory and start all over. Donnie later learns that The Foot are working on a mind control formula.

In Clash of the Mutanimals, the planned Mind Control Serum is complete by Baxter Stockman while Saki examines the mentally unstable Karai caged. Rather than use Karai as a weapon, Shredder orders Stockman to place the Brain Worms into the minds of Slash and Dr. Rockwell (previously captured by Tiger Claw at the docks) as test subjects. Shredder later appears after Raphael, who was captured by Rockwell and Slash, is subjected to the same experimentation. Despite Raphael wanting to defeat Shredder permanently, he falls to the injected worm's control. When the other Turtles and remaining Mutanimals arrive in a rescue attempt, Shredder orders the three brainwashed mutants, Stockman, and Tiger Claw to eliminate the guests; Shredder watches over the battle from a throne surrounded by flames. After Rockwell, Slash, and Raphael are freed Shredder decides to take matters into his own hands, combating all eight mutants with relative ease. While battling Leonardo and Raphael, Slash and Leatherhead are able to push a statue down to blindside Shredder before escaping when Tiger Claw and Stockman return with reinforcements. Once freed by the Foot Bots, Shredder bellows in anger for another failure to eliminate his enemies.

In The Deadly Venom, Shredder only appears at the episode's beginning. After Karai is administered the brain worm by Baxter Stockman and easily defeats Rocksteady, he orders his mind controlled "daughter" with a mission: the elimination of the Turtles, Casey Jones, April O'Neil, and Splinter.

In Tale of the Yokai, a young Oroku Saki appears during the Turtles' battle with the Hamato Clan, referring to the deities as yokai, ancient Japanese monsters before Michelangelo throws a smoke bomb to escape. Saki goes to the dojo to explain to Hamato Yuuta of his encounter, only to be dismissed by an arrogant and younger Hamato Yoshi. The two "brothers" then combat one another in sparring; the duel turns intense over the mentioning of Tang Shen, with Saki claiming his friend doesn't love her. Knocking him down, Yoshi offers a hand to his friend only for Saki to bitterly reject the kind gesture. Later at night, Saki shockingly protects Shen and her daughter Miwa when the Turtles foolishly behave which causes Miwa to cry. Oroku reveals to Shen of overhearing an earlier conversation between her and Yoshi of the latter's refusal to move to New York and is willing to fill Yoshi's role, claiming to be a changed man before softly kissing her forehead. The tenderness of Saki is seen by Yoshi; when dueling with Saki again, Yoshi fights angrily, demanding to know of the discussion between his wife and "brother". Despite Yuuta's attempts of calming the two, jealousy and bitterness harms Yoshi and Saki's friendship. Out of a lust for vengeance, Saki offscreen drills several Hamato Clan ninjas of the clan's ignorance. Desiring revenge, he torches a shrine and declares the Foot Clan's rise once more; his first target is none other than his former "brother" Hamato Yoshi. Armed with two claw gauntlets, Saki attacks the couple out of rejection and insanity, refusing to stop his merciless attack on Yoshi from the conflicts he's fought overtime. As shown from Splinter's previous flashbacks earlier in the series, Saki's assault results in the dojo's incineration; when Shen renters the dojo to prevent further harm, Orkou Saki commits an accidental fatal slash, killing Shen. Though he attempts to save Shen's body, a piece of burning debris hits Saki, giving him the face burn as a reminder of the tragic day. He then takes Miwa away where he restarts the Foot Clan under a new moniker: The Shredder.

In Attack of the Mega Shredder!, Shredder is watching as Karai, in her mutated state, is being repeatedly injected with mind-control worms. He shows no remorse in what he's doing, instead apologizing for his actions and how they will have their revenge soon. He then requests that Bebop and Rocksteady double the security as he senses the Turtles will attempt another move against him, threatening them with punishment if they fail again. Though the Turtles make it into the catacombs and are beaten back by Bebop, Rocksteady, Tiger Claw, and the Shredder Elite, Shredder is still furious and threatens to punish all of them if it happens again. In an attempt to make it up to him, Bebop and Rocksteady try to help as they manage to capture Mikey and Leo when they infiltrate Stockman's lab alone, but thanks to the turtle brothers suggesting adding the Shredder Elite to what Bebop and Rocksteady intend to do to them, it results in the three Shredder mutants being fused into the Mega Shredder, an amalgamation of all three that proves to be a difficult enemy to the Turtles. After it has been destroyed by the Turtles, Shredder is furious with Bebop and Rocksteady over their stupid act, and leaves Tiger Claw to punish them for their actions.

In Annihilation Earth!, Shredder is surprised to find April and Splinter having infiltrated his lair and wonders why. Splinter requests that they call a truce and unite to stop the Triceratons from destroying the Earth with the Heart of Darkness. When he hesitates as to why he would join forces with his sworn enemy, April tells Shredder that if the Earth is destroyed, he will never see Karai again. Taking this into account, Shredder agrees to the truce between the Hamato and Foot clans, and has his mutant lackeys assist in fighting the Triceratons. However, with the timer on the Heart of Darkness detonator reaching zero, Splinter calls Shredder to help stop it, but instead of saving the Earth, Shredder condemns it to annihilation as he seizes the moment, and murders Splinter in cold blood, finally attaining his vengeance: this resulted in April blasting him back with a psychic blast. When Tiger Claw calls him up on this as they are about to be sucked up by the black hole, Shredder shows no remorse in what he has done, only happy to know that his long-time enemy is finally dead and the clan war between him and Splinter has ended in victory for him. With that, Shredder and his lackeys are among the first victims to be sucked up by the black hole to their doom.

Although a cameo in The Arena of Carnage, Shredder appears as a hologram aboard the Ulixes' training station, viewing the fights between the Turtles and his minions, which abruptly ends by the Fugitoid.

In Earth's Last Stand, after the Turtles time travel back to save the Earth, future Leo warns Splinter of Shredder's impending betrayal, resulting in the outcome changing. Livid that Shredder would break their alliance, Splinter fought back against Shredder, who blamed Splinter over how Karai is gone, ultimately besting him in combat, leaving his immobile body to be carried off by Tiger Claw, who vows that the Foot will return.

In City at War, due to the injuries he sustained from Splinter, Shredder has been confined to a hospital bed under the care of Stockman with Bebop and Rocksteady as his bodyguards. When Tiger Claw returns to report the loss of a entire weapons cache thanks to the Turtles and Karai back in Manhattan, making it clear Karai wants to take Shredder down one piece at a time by destroying his criminal empire before taking him out, Shredder decrees that if it's a war Karai wants, it's a war she'll get, before Stockman hooks an I.V. filled with mutagen up to Shredder, and as the mutagen is injected into Shredder, his eyes open wide as the mutagen takes effect.

In The Insecta Trifecta, Shredder is still receiving the mutagen drip as he now turns to Stockman as his last hope due to his undying loyalty since Tiger Claw and the others have become useless as of late in stopping Karai and the Turtles. When Stockman returns to report his mission a failure, Shredder is not worried about it, revealing to Stockman that his mutagen drip is finally taking effect as Shredder deploys a pair of blades from the back of his hand, right out of the skin itself.

In The Super Shredder, though his recovery is doing well, Shredder grows impatient, and orders Stockman to inject the rest of the mutagen into him at once, despite Stockman's pleads that it needs to be stabilized first or the effects could warp Shredder's mind towards insanity. Stockman reluctantly does as ordered, but as Shredder starts to get up, the unstable mutagen kicks in, causing him to thrash around the room, grabbing the Kuro Kabuto and putting it on, before fully mutating into his Super Shredder form, just as Rocksteady enters to see what happened when he heard Shredder scream in pain. Tiger Claw arrives shortly thereafter, and immediately demands to know what happened from Stockman, before Shredder tells them it is time to bait the trap for Splinter, and orders them to fetch Rahzar. After cutting power to the Turtles's lair and his old headquarters where Karai was now stationed, Shredder arrives with Tiger Claw and Rahzar, and confronts Karai. Despite the best efforts of Karai, Shinigami, and their Foot Ninja, Shredder overpowers all of them, before forcing Karai to surrender to him under threat of hunting down Shinigami if she doesn't. Once outside, with Karai his prisoner, Shredder is confronted by the Turtles and April in the Shellraiser, but when they try to charge him, he easily lifts the front of the Shellraiser off the ground, before delivering an ultimatum to them to take to Splinter: If Splinter ever wants to see Miwa again, meet Shredder at the last place where they fought and Shredder beat him. With that, Shredder tosses the Shellraiser across the street, then ignites the leaking fluid from the Shellraiser, engulfing it in flames.

Taking Karai to where he sets up his trap for the Turtles and Splinter, Shredder begins his trap by luring Splinter away from the Turtles with various photographs of his and Splinter's past regarding Tang Shen, Karai, and other moments, setting them ablaze, before finally confronting him when he arrives where Karai is being held hostage. Shredder proves too powerful for Splinter, and Splinter is forced to use a smoke bomb to escape and lure Shredder to where Splinter fought The Rat King. Though Splinter has the advantage at first, Shredder soon has him right where he wants him, but before Shredder can finish the job, his arm begins to act crazily, a side-effect of the unstable mutagen that Stockman had warned of. Despite that, Shredder soon manages to crush one of Splinter's feet under his own and prepares to kill him, but a distraction from the Turtles, April, and Karai, gives Splinter the chance to toss a kunai at where he had set up several explosives, detonating them and causing the segment of broken bridge Shredder and he were on to crumble and collapse. Shredder tries to jump to safety to go after the Turtles, April, and Karai, but Splinter manages to grab him, and both of them plunge into the abyss, presumably to their deaths, leaving Bebop, Rocksteady, and an army of Chrome Dome Elite Foot-bots to deal with the Turtles, April, and Karai now that they lost their Sensei and father. Whether or not he survived is left for debate.

In Darkest Plight, Shredder survives the fall Splinter pulled him into by landing on an I-beam, while Splinter falls deeper into the chasm, but cannot pull himself back up to the top of the under-city due to the damage his left hand suffered from the unstable mutagen. Tiger Claw helps him back up, but is horrified when he sees Shredder's hand, and pleads with him to avoid taking any more mutagen as it could be deadly. However, Shredder ignores this, and orders that Zeck and Steranko remain behind to ensure Splinter's dead while he and Tiger Claw return to his hideout to recover before resuming the hunt for the Turtles, April, and Karai.

Once recovered, Shredder and Tiger Claw return to hunt them down, and upon finding Leo, Karai, and April, Shredder orders Tiger Claw to go after the girls while he deals with Leo. They attempt to draw Shredder and Tiger Claw to the surface, but Shredder soon finds Leo lying in a pile of garbage bags, grabs him, and flings him out into the street, in full view of several innocent civilians who run for their lives upon seeing Super Shredder. Grabbing Leo, Shredder starts to squeeze him to death between his hands, before being interrupted by April and Karai. At one point, April seems to have the advantage over Shredder thanks to her psychic powers, but when Shredder is slammed into a building by a fuel tanker semi-truck, he throws it towards Karai, only for April to catch it in her psychic grip, and after having her eyes glow blue and smile malevolently thanks to her Sol Star crystal aiding her, April flings it back at Shredder, before collapsing in fatigue. Shredder prepares to finish off Leonardo, but Karai intervenes, pleading for him to do something good in his life instead of waste it on his vengeance. Moved by that, Shredder attempts to apologize to Karai for his behavior, but Karai reveals she was simply luring Shredder in as she punches him right in his exposed mutated heart, weakening him so his hands begin to fall apart again from lack of stable mutagen. Before Karai can finish him, Tiger Claw arrives to evacuate him back to their hideout, and Karai does not pursue as she helps April get Leo home for medical attention.

Once back at his hideout, Shredder demands a larger dose of the mutagen from Stockman, but Tiger Claw intervenes, saying it is too dangerous, only to be overpowered as Shredder forces Stockman to administer the dosage. Tiger Claw can only watch in shock, disbelief, and fear, as Shredder lets out an enraged scream as the mutagen takes effect.

At the start of Tale of Tiger Claw, Super Shredder contacts Tiger Claw via a M.O.U.S.E.R.S hologram to let him know of needing him to hunt down Karai while he is still waiting for Stockman to finish perfecting the mutagen so Shredder will no longer have to worry about his mutated body falling apart on him while fighting the Turtles and Karai.

At the beginning of Requiem, Super Shredder checks on Stockman, who has finally perfected the mutagen and injects a dose of the perfected super mutagen into Shredder, causing him to spawn more blades on his body, and feel his body feeling stronger and more stable now. Deciding to test it out on some Elite Foot-bots and a hologram of Karai, Shredder shows no remorse as he cuts the hologram Karai down, and prepares to face Karai and Splinter once and for all when word arrives that Karai and Shinigami are hiding out at the Mighty Mutanimals' hideout in the Bronx. Super Shredder lays siege to the place and sets it on fire, overpowering all the Mutanimals before confronting Karai, taunting her at how she'll be meeting the same fate as her mother with dying in an inferno. When Karai tries to run Shredder's mutated heart through with her tanto blade, the stabilized mutagen causes her blade to break, and Shredder throws her to the ground to be buried under rubble and left to perish in the fire.

Afterwards, he waits for Splinter at the Wolf Hotel, the very same place he first fought the Turtles before his mutation. He easily overpowers and knocks out Slash, badly wounds Raphael, wounds April on her arm, and throws Casey off the building, only for him to survive thanks to his grapple hook, before facing Splinter. At one point, it looks like Shredder loses as Splinter trips him up and flings him off the roof, but Shredder recovers and ambushes Splinter, running him through the chest with his blades and finally killing him, attaining his vengeance. However, Super Shredder only enjoys his victory for a short while before a furious April calmly blasts him off the roof with her psychic powers, sending him crashing into the back of a garbage truck, where Casey activates the crusher, hoping to end Shredder's life and avenge Splinter immediately. However, after the Turtles leave in the Shellraiser with Splinter's body, Super Shredder punches his way out of the garbage truck through the roof.

In Owari, as Lenoardo grieves over the death of his father, he hears from the spirit of Splinter that Super Shredder is still alive and he must ensure that he is finally defeated. The Turtles visit Karai, who is hospitalized after her previous fight with Shredder, and she reveals the location of his hideout, and they along with April and Casey prepare for battle.

After making it to the hideout, fighting much of the Foot Clan's forces including Foot-bots, Fishface, Stockman Bebop and Rocksteady, and Tiger Claw, the Turtles, April, and Casey, are confronted by the Super Shredder, who throws Molotov cocktails at them from the from the roof of the mansion. Casey and April are cut off as the flames spread, leaving the Turtles to go after Super Shredder alone.

Super Shredder expresses how he believes that the Turtles would leave the city after Splinter was defeated as they in the The Invasion, Part 2, but the Turtles state that the would not run that everything would end tonight. The Super Shredder tosses off his cape and they five engage in battle.

The Turtles each attack with the best of their abilities, but the Super Shredder proves to be stronger and overwhelms them while mocking their tactics. The fight becomes more intense as the Turtles pin Super Shredder down and even dose him with Donatello's vial of retro-mutagen, but Super Shredder proves to be invulnerable.

Back on his feet, Super Shredder attacks, throwing Donatello, Michelangelo, and Raphael one by one off the roof until he and Leonardo are the only ones left. In the midst of the duel Leo furiously reminds Super Shredder that he killed Splinter, his brother and best friend, also questioning how could he do it. As Super Shredder beats Leo, he replies that Splinter was cursed from the beginning to become a lonesome rat, that he refused to fight his destiny. However, Leonard snaps at Super Shredder, referring to him as a monster, a demon, and asks if it was his destiny to be one. For brief moment of humanity, Super Shredder considers Leonardo's word and hesitates to kill him. Leonardo takes advantage and attempts to strikes, but Super Shredder overpowers and disarms him and tosses him aside. Super Shredder walks over to the battered Leonardo with blades at the ready and prepares to finish him off. However, Leonardo sees Splinter's spirit once more and is told to fear nothing. Leonard rises and fend off Super Shredder with a powerful assault of blows before retrieving his katana. Now armed, both and Leonardo and Super Shredder charge in the air at each other and Leo strikes Super Shredder with fatal blow before the two vanish within the fires.

The mansion becomes engulfed in flames and the rest of the Turtles, April, and Casey wait below, worried for Leonardo. An injured Leo suddenly appears with the mutated Kuro Kabuto in hand and declares that the Super Shredder in finished before dropping it to the ground.

## Personality

The Shredder is known for fighting with reckless ferocity, showing little mercy to anyone who stands between him and his conquest. Even though he finds himself within a city swarming with various mutant creatures and aliens from different Dimensions, the Shredder generally views it all as nothing but a distraction from his ultimate goal; his vendetta against Hamato Yoshi. He once seemed to care about Hamato's biological daughter (Karai, who he still considers to be nothing but a trophy gained by one of his initial victories), but, after Karai realizes just how dishonorable the Shredder is, he figures that she barely serves a purpose anymore and has Tiger Claw lock her up in a Dungeon. However, after Karai is accidentally mutated because of himself, the Shredder does become slightly sad, but doesn't take responsibly for his own actions. The Shredder is even wicked enough to tell Miwa lies about her mother's death in order to make her believe that Splinter was the one responsible for it.

The Shredder is also known for his disdain and intolerance towards failure, as he has scolded and threatened Rahzar,Fishface, and Baxter Stockman for being incapable of fulfilling his designated desires at some points; primarily where the turtles and Splinter are concerned. This seems to extend to his own failings, as when he first fought (and defeated) the turtles, because he was distracted by the mutation of Bradford and Montes, he was not able to finish them off due to their stealthily escaping him; much to his dismay. This seems to happen consistently, as in Wormquake!, he expressed rage when Leo, Raph, and Mikey managed to save Splinter from his wrath and escape his sight and vehemently commanded his underlings to follow them. He later displayed aggravation in Return to New York when the turtles, April, Casey, and the mentally restored Splinter managed to again escape his sight. Also, in Serpent Hunt, when Shredder once again overpowered the turtles, Leo manages to outsmart him by throwing smoke bombs in his face so that he and his brothers could escape once more; which causes the Shredder to become furious (especially when the turtles' actions are what resulted in Serpent Karai's own escape).

## Abilities, Skills and Weaponry

**Ninjutsu:** As a master of ninjutsu, his skills are very high, beyond what most other ninja could reach, since he has been training for years and has learned forbidden ninjutsu arts. So far he is able to easily defeat all of the turtles, and duel for long, brutal periods against Splinter, who has skills that are equal to or even greater than his own (he did defeat him twice, once as a human and the second time as mutant). He even knows a forbidden skill that is so clever and effective that it surprised even Splinter (when he was still going by "Hamato Yoshi" in Japan).

**Strength:** His abilities are quite amazing for a human to have. He has shown that he has immense strength, and is much stronger then the average person as he can lift Splinter's weight with only one arm. He was even strong enough to battle large mutants like Leatherhead in a short, but brutal fight; as he was strong enough to injure him. He has shown that he is able to push around heavy mutations like Dogpound or Rocksteady (although, this may be via technique rather than strength).

**Speed:**Despite being a man of considerable bulk, he has proven to be much faster than the Turtles and is arguably just as fast as Splinter. After their first fight with him, both Mikey and Donnie have commented on his speed, with the latter stating "it was like he was everywhere at once". He has great acrobatics and seems to be adaptable in combat, his agility is shown when fighting against Leatherhead. He can also jump higher than the average athlete.

**Stealth:**He is very stealthy, easily surprising enemies. Shredder was even able to slip behind Leonardo before the blue-masked turtle could even turn to notice.

**Steel Claws:**His weaponry consists of two sharp claws around both his arms that even have a middle weapon that can slide out. His body is covered by powerful armor that can protect him from a lot of attacks, even Leatherhead's powerful jaw strength and sharp teeth.

**Intelligence:**His intelligence is quite high especially knowing that his old friend Master Splinter is training ninjas. He seeks ways to create a better army; having people train to be Ninjas, using alien technology, and making mutants to at least destroy his most hated foe.

**Business Knowledge:** With this he was able to transform the Foot Clan from an old, fallen ninja group into an international criminal organisation. Shredder's capable of making deals with criminals such as the Purple Dragons, Tiger Claw, Ivan Steranko, Don Vizioso etc.

**Stamina and Endurance:** Both are also high for his age as being 48 years old and are enough that he was able to take the jaw strength of Leatherhead, but the type of armor that he wears could be very proactive for his body to take many blows. As he was fighting off Splinter, Leatherhead interfered, but his stamina allowed him to fight back and defeat him. In the episode "The Invasion" Splinter used his special skill of using his fingers to push opponents to the wall, which defeats most opponents, but Shredder was able to get back up and continue to fight Splinter. Though it is revealed that his arm was wounded but still was able to use it to flush Splinter. He even got hit in the face by Mikey without showing discomfort (although, this may be due to the Kuro Kabuto helmet he wears, as Shredder himself once stated that the helmet has never been and {most likely} can never be damaged).

## Trivia

* In Splinter's flashbacks, Shredder is seen wielding a pair of "Tekkō-kagi" (lit. "back of the hand hooks"). In the present, he is seen with custom-made Tekko-kagi claw weapons: They have extendable blades and are razor sharp. They have also been shown to be strong enough to cut through metal shipping containers.
* The Shredder's real given name "Saki" is (usually) a female Japanese name that means "blossom" and "hope".
* He owns an Akita Inu named Hachiko. Hachiko contributed to Chris Bradford's mutation by biting him before the Mutagen spilled on him.
* Oroku Saki's Super Shredder mutation, bares a distinct resemblance to Doomsday a monster from DC comics, with a similar changes on his normal bone weapons into steel bone weapons like Marvel's Wolverine as his further mutation.
* Super Shredder's death at Owari was originally supposed to involved his head being sliced off by Leonardo, but was heavily censored due to the show's aim at a younger audience. However, the full image of the decapitation can be viewed on Ciro Nieli's Instagram: https://www.instagram.com/p/BQ-66EJj2yX/.
