Hamato Karai is the leader and founder of the Hamato Clan. She is also the daughter of Foot Clan leader Oroku Saki, who later became her most hated enemy, the Shredder.

Physical Appearance

Hamato Karai is a middle-aged Japanese woman with long straight graying black hair styled in a high ponytail, black eyes, light skin, and a thin figure. She wears a sage green jumpsuit with 3/4 sleeves, silver pauldrons, and a light olive green sash around her waist that drapes on both sides of her body with the Hamato Clan emblem placed on the center. She also wears black fingerless gloves, black and silver knee-high boots, a fern green scarf, and a matching hair tie.


Karai is warmhearted and honest, however, she can be stern and serious if the situation demands it. She is grandmotherly towards the Turtles and is shown to be proud of who her descendants are. She is capable of inspiring and motivating others, visible in her interactions with Raphael in "Anatawa Hitorijanai".

Karai has a strong sense of justice, willing to leave her birth clan and create another to combat the terror spread by the Shredder and the Foot. She is also very dedicated to her family, having sacrificed herself twice to save them. The first time trapping herself in an alternant dimension to repel her father for eternity and the second time to protect the Turtles from the Shredder's violence in "Shreddy or Not", partaking in a fight that ends her life, but death does not stop Karai from being with her family as her devotion to them continues even as a spirit.

Karai has an accepting and understanding nature shown in her easy embrace of Splinter and the Turtles' species and in her gentleness towards Splinter's lack of education he instilled in his sons involving their clan's culture in "Shreddy or Not".


Many Years Ago

Karai was born 500 years ago to her father Oroku Saki as a member of the Foot Clan. She was a young child when her clan was ravaged by another clan, bringing an end to her tranquil childhood. An Oni gave her father the Kuroi Yōroi, an evil, but very powerful suit of mystic armor which he used to protect the Foot from the threat of the attacking clan. The armor corrupted Karai's father into a demon and he twisted the Foot into a violent, destructive clan, leading it as the Shredder. Karai then made the decision to defect from the Foot and establish the Hamato Clan to fight against the Shredder's cruelty. During her and her clan's struggle with him, Karai came to learn that no mortal weapon could harm him and so she utilized Hamato Ninpō to eternally lock herself and him in the Twilight Realm to ensure that even if the Kuroi Yōroi was successfully reassembled, the Shredder would be unable to overcome his weakened state.

Modern Day

Karai was first depicted in "Shadow of Evil" as Splinter informed April O'Neil of the Shredder's mythology after realizing that the Foot was genuinely working to resurrect him.

Karai debuted in "Finale Part 1: E-Turtle Sunshine of the Spotless Mind". To her horror, Baron Draxum accessed the Twilight Realm and Splinter and the Mad Dogs pulled her from it, empowering the Shredder to regain his full strength due to her absence, and she was briefly rendered unconscious after regaining her human body.

After waking in "Finale Part 2: Shreddy or Not", Karai quickly came to understand that Splinter and the Turtles were her relatives. She explained to them her role in the Shredder's banishment and how the Shredder came into existence, stating that she herself was the weapon that defeated and confined him. Exhausted from her residence in the Twilight Realm, Karai then sought to rest, but her sleep was disrupted by the Turtles' efforts to bond with her. She resolved to instruct them on accessing their Hamato Ninpō, but was unable to due the Shredder and the Foot's sudden invasion of the lair. Too weak to confront him at the moment, she evaded the Shredder through Leonardo's mystic portal, hiding in Donatello's laboratory while Draxum, Splinter, and the Turtles fought. Karai's location was quickly discovered by the Shredder and he entered the laboratory, striking down Karai's impromptu bodyguard S.H.E.L.L.D.O.N. and attempting to attack her. She was vulnerable as she was still unable to harness her Ninpō, but fortunately, Raph seized the Shredder before he could inflict any harm on her, throwing him into the lair's atrium. However, Karai chose to rescue Raph after the Shredder had him in his grasp. She used her Ninpō against the Shredder and he intercepted her strike from her mystic blade, destroying it. She was then grabbed by him and she, in turn, attacked his body with an intense discharge of her Ninpō in a direct hit, causing his chest split open. Shaken by the sight of Saki's soul during her attack, Karai was unable to defend against or evade impalement from the Shredder and offered reassuring words to the Turtles before they fled the scene.

In "Finale Part 3: Anatawa Hitorijanai", Karai laid dying in the now-deserted lair when April returned and discovered her. Karai stopped her attempt to help her and transferred her soul into April's body, succumbing to her chest injury soon after. The transferral allowed her to communicate with April and she instructed her to seek out the Turtles. Later, April found the Turtles at Cuddle Cakes Puppy Rescue where Karai gave her the information to relay to them about unlocking their Ninpō. When Raph became despondent about the situation involving the Shredder and the Foot, Karai met with and consoled him, helping him understand that familial trust is essential to accessing their clan's Ninpō. This allowed Raph and his brothers to tap into their Ninpō and be ready to challenge the Shredder.

Karai fought alongside April in her and the Turtles' battle against the Shredder in "Finale Part 4: Rise" and struck him herself with April's mystic baseball bat. She aided in delivering the final blow on the Shredder and her ghost departed from April's body afterward. His death allowed Karai to reunite with her beloved father and she thanked the living Hamato Clan and its allies for their efforts, disappearing with the ghosts of the clan's previous generations.


  • Kenjutsu: Karai has been shown wielding a short sword with a straight blade, squared guard, dark red grip with geometric engravings, and a golden snake with red eyes and a gaping mouth that wraps around the sword's hilt and beyond its matching guard in "Shadow of Evil" and "E-Turtle Sunshine of the Spotless Mind". However, her level of proficiency with it is currently unknown.
  • Ninjutsu: Karai is a practitioner of the art of ninjustu and is presumably highly skilled.
    • Hamato Ninpō: Karai is the one who knows the Ninpō to defeat her father. With this, her agility is enhanced, she is strengthened to extreme levels, and becomes incredibly swift. It is unknown what her full potential is with this power as the Shredder states in "Shreddy or Not" that she has been weakened, along with where this power comes from scientifically, besides spiritual connection.
      • Weapon transformation: Karai can create a weapon from anything within her hands, as shown when she turns Donnie's sculpture to create a dagger powerful enough to temporarily puncture the Shredder's armor. She can also use somewhat of a telekinetic ability when she turns blades made by the Shredder against him. Karai is able to take this ability a step further and even turn herself into a weapon, namely a sword, a form she took for centuries to seal the Shredder in his prison dimension.
      • Soul transferal: Karai has the ability to move her soul into the body of another, giving her the ability to communicate with and strengthen her host. It is currently unknown if she was capable of this while she was alive as well or only upon/near death.



  • Hamato Karai's parent(s)
    • Oroku Saki / The Shredder: Saki is Karai's father. She deeply cares for him and became devastated that he was consumed by the Kuroi Yōroi. She founded the Hamato Clan and sacrificed herself to banish her and her father to the Twilight Realm. She, along with her family, destroyed the Shredder once and for all in "Rise" and Saki was freed, whom she captured in a loving embrace.
  • The Mad Dogs: The Mad Dogs are Karai's latest descendants. She loves them dearly despite having the chance to interact with them for only a short time.
    • Donatello: Donnie is Karai's descendant. Though she was confused by Donnie's modern technology as a consequence of her being gone for centuries, she was ultimately impressed by it, to which Donnie becomes so happy that he finally recieved praise from the elder generation.
    • Raphael: Raph is Karai's descendant. In "Anatawa Hitorijanai", Karai showed affectionate support towards Raph stating that he is never alone. Raph and Karai get along very well.
    • Leonardo: Leo is Karai's descendant. Both get along very well and have a loving and affectionate relationship. When the Shredder arrived to destroy Karai, Leo teleported himself and Karai to Donnie's laboratory where he asked S.H.E.L.L.D.O.N. to protect her, sharing a hug with him before he left.
    • Michelangelo: Mikey is Karai's descendant. Both get along quite well and Karai happily received a portrait of their family from him, a gift she cherished through her final moments of life.
    • April O'Neil: Karai shares a caring and loving relationship with April. While not biologically related to her, Karai wholeheartedly considers April as a member of their clan and always has as expressed in "Anatawa Hitorijanai". Upon her death, Karai's soul temporarily resided within April's body to help her face the Shredder.
  • Hamato Yoshi / Lou Jitsu / Splinter: Splinter is Karai's descendant. While she was dismayed to learn that Splinter had not taught his sons Hamato Ninpō, she approves of the values he taught them and believes that he has strengthened and remained true to their clan with his efforts.

Friends and Allies

  • S.H.E.L.L.D.O.N.: Karai was amazed by S.H.E.L.L.D.O.N. when Donnie showed him to her and was protected from the Shredder by him in "Shreddy or Not", albeit very briefly.



  • Like Hamato Koji in the 1987–1996 animated TV series (who was the founder of Yoshi's Clan, the Foot), Karai was the founder of Yoshi's Ninja Clan, the Hamato Clan.
  • Karai is voiced by Gwendoline Yeo, the same actress who voiced Shinigami in the 2012 TV series.
  • This is the first television incarnation of Karai to be biologically related to the Shredder, and the second version to be related to him in TMNT overall after Oroku Karai in the IDW comics.
    • She is also the first version of Karai to be the biological daughter of the Shredder.
    • She is also the second version overall to be biologically related to Splinter, and through her, Splinter and the Turtles are the first versions of their characters to be directly biologically related to Oroku Saki.
