Shredder

Oroku Saki, also known as Shredder is the main antagonist from the Teenage Mutant Ninja Turtles franchise.

Shredder was a master of Ninjutsu who was an arch-enemy to Splinter and the turtles, the former 'adoptive father' of Karai, the fearless leader of The Foot Clan, and one of the two main antagonists of the series, the other one being Kraang Prime.

After fully recovered from his recuperation, in the episode City at War, Oroku Saki has become a Super Mutant known as Super Shredder.

Appearance
In this version, the Shredder is slim but tall, muscular and toned with bigger and bulkier prongs on his shiny chrome-plated armor. He still remains keeping the shoulder, arm, and leg gauntlets, with his hand 'claws' merged with the arm gauntlets and wears a violet cape. Unlike most incarnations, this version of the Shredder has a horrid wound going down the right side and bottom of his face, which he received when he attacked Yoshi in his home and ignited a huge fire (presumably). He once had black hair and a completely natural face, but he also lost both of these aspects during the fire. He now suffers from severe burns, though he is still surprisingly competent as a fighter. It is still debatable whether or not he lost the sight of his right eye in the fire, as it is now blood red with just a blue iris in the middle of it.

As Super Shredder, his body underwent hideous disfigurement. His helmet has also fused with his head; its own blades becoming longer and spikier and its frontal mask resembling a human skull's face. He also has ten Mutagen cores on his forehead, two thin nostrils, glowing green eyes; which are bloodshot, and his teeth and gums are visible under his Kuro Kabuto. Hanging around from the back area of his head, Super Shredder has a torn piece of his purple robe that acts like his helmet's shikoro. His skin has a few areas with a peach-orange hue, purple, and reddish-pink hue with a few swollen areas and Mutagen veins (around the chest, arms, and spikes). His body has become more muscular with metal blades sticking out of almost every part of his body, as a few silver, metallic spikes that pop out from his chest that look like ribs. On each of his shoulders, he has three spikes emerging from the skin, as well has three spikes on each of his arms. His fingers are covered in metal that have sharp fingertips (like claws) and sharp knuckles. Around the knuckles for each of his hands, he has two retractable, steel claws that are longer than his fingers. On his back, he has three spikes on his spine that are unequal in length. In the center of his chest, he has a big exposed beating heart with a purplish-blue hue that is surrounded with Mutagen veins. The only clothing he wears now are his tattered pants, bandages wrapped around his clawed feet. Hanging from his shoulder spikes, Super Shredder, has a tattered cape.

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's immense capacity for hatred seems to stem from an inability to accept his own failures and bad actions 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 the suffering and misfortune he endures, and considers anyone linked to Splinter to be just as guilty. He believes that anyone who has contributed to his misfortunes should pay with their lives.

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).

During his recovery, Shredder startedbelieving his own lies about his and Splinter's relationship to the point where he actualy believed that Splinter killed Tang Shen and that Karai was his daughter who was brainwashed against him, (beliefs that Karai and Splinter call him out on) driving himself more insane than before and becomeing more obsessed with destroying Splinter and getting his "daughter" back from him, which resaulted in him sacrificing his humanity by having himself mutated so he could use his greater mutant form to kill Splinter and his family. Later on he traind himself to feel no emotion or attachment to anyone, to the point that he had no qualms about trying to (and almost succeding in) kill Karai (whom he'd raised as his own child) and mocked Tang Shen's death.

As Shredder
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 (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).

Peak Human 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). By himself, he was able to overpower and defeat both the turtles and their allies the Mighty Mutanimals leaving them all downed and wounded.

Peak Human Speed and Agility: 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 organization. Shredder's capable of making deals with criminals such as the Purple Dragons, Tiger Claw, Ivan Steranko, Don Vizioso etc.

Peak Human Stamina and Endurance: Both are also high for his age as being 50 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).

As Super Shredder
As Super Shredder, his new form made himself to be one extremely powerful opponent for the Turtles.

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.

Ninjutsu: As a ninja master, he still maintains his Ninjutsu skills, which he uses in combat.

Super Strength: Super Shredder is shown to be able to lift and toss a charging Shellraiser and a tanker truck that weighted few tons. He was able to over power Leatherhead and Slash very easily with few hits.

Steel/Bone Blades: One of Super Shredder's most noteworthy powers is his serrated blade coming out of his body. Similarly to his Steel Claws, he can create two out of his arms, longer than his Steel Gauntlets.

Enhanced Senses: Shredder's sense of smell and hearing has also greatly improved, allowing to track Splinter as he was hiding.

Durability and Stamina: From his base form he was able to take many attacks from Splinter but as this Super form he can resist it far better then before such as from falling tall building and able to surrive form the garbage disposal.

Shredder Mutagen: If his body was cut as his green slime as mutagen as proven to be true that he can make anyone into appearance of looking like Shredder as mutant. As the Shredder slaves are proven to be quite powerful and fast. They can spread this to others to have Shredder memories.

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 ironically means "blossom" and "hope".
 * He owns an Akita Inu named Hachiko. Hachiko contributed to Dogpound's mutation by biting him before the mutagen spilled on him.
 * It is unknown why Shredder was sick and dying prior to his mutation, although there are a few possibilities:
 * His helmet was removed for a long period of time, and therefore not covering the areas of his face that had no skin on them, making it easier for him to be infected.
 * The jabs Splinter made his pressure points at his chest and stomach areas, which could have stopped his organs from working properly.
 * In an original scene from "Owari", it was shown that Super Shredder was decapitated by Leonardo but it was censored, although blood can still be seen on Leo's sword.
 * The 2012 version of the Shredder is considered to be the darkest & most murderous version of Oroku Sakiyet.
