Revision as of 02:33, 9 June 2014

Karai is a rebellious member of the Foot Clan, a master kunoichi, and the 16-year-old adoptive daughter of The Shredder. She is voiced by Kelly Hu in this variation.

Karai was also revealed to be Hamato Yoshi's missing, biological daughter, Miwa, in Showdown, Part 2.

History

In her debut episode, New Girl in Town, she and Leonardo immediately have a similar relationship to that of Batman and Catwoman; as she tries tempting him to be more like her, while Leo wants her to see she's not as bad as she appears. Karai confronts Leo, who is separated from his brothers when he and Raphael have a heated argument over who should be their leader. During their first battle, she temporarily blinds him before attacking him. However, she leaves him alive. She later runs into him again in an alley and fights him again. They both exchange some banter and some blows until Karai holds a sword against Leo's throat, trying to convince him that he's not as good as he appears. She also notes during her fight with Leonardo that she understands the Shredder's revenge, but she's uninterested. And that, she jokingly stated, he (the Shredder) should get a hobby. She tells Leo to meet her at the top of a building without giving him any more information other than she wants to show him something.

At midnight, Leo meets Karai on top of the building she informed him about earlier. She tells him that they're there to steal a famous katana, which is clearly visible in a museum window down below. Leo refuses to help her which upsets her. Before she takes out her katana, Leo stops her and tells her that he believes that there's good inside her. Raphael then shows up, and is angry at him for "holding hands with the Foot."  Upon Snakeweed's attack, she stands there smiling, until Leo asks for her help. She throws her knife above the wall near his head and leaves. Whether this was to help him or not is undetermined.

Karai meets with The Shredder, who is not happy that she let Leo live. She tries to talk her way out of it and say that he escaped, but The Shredder doesn't believe her. He tells her that she must kill him next time, or else... Their scene ends with Karai addressing him as "father". Her relationship with her "father" may be somewhat precarious, as she becomes frightened after making The Shredder angry at one of her comments.

In The Alien Agenda, Karai finds the Turtles fighting The Kraang. She becomes somewhat concerned over The Kraang, yet intrigued. When she informs The Shredder of this, she tries to convince him to take some concern over them, due to the mutations that happened to the Turtles, Xever and Chris Bradford. Shredder believes that this is all nonsense, and dismisses her suggestions. She becomes relatively disappointed that her adoptive father has no interests or concern over The Kraang. Shredder then reminds his daughter of his reason for his ongoing vendetta against Splinter. To find out more about The Kraang, she questions Leonardo when the two happen to encounter each other on a rooftop, during which she playfully flirts with him. But he refuses to tell her anything, warning her that the robots are dangerous, while also telling her to leave him and his brothers alone. Raphael asks Leonardo about her, and if they should tell the other two brothers about her and his "relationship", but Leonardo says that the two already had a 'chat' and confirmed that she's going to leave them alone. Raphael thinks that telling her to back off is a pointless idea. She keeps it to a point, as she followed the 4 brothers into The Worldwide Genome Project (which is actually run by The Kraang in secret) building, seemingly undetected. However, when the Turtles realize that Raph was missing, he has found Karai and pins her down. The two fight, but it's not long before Leonardo breaks up the skirmish. When Raph makes a comment, Leonardo argues that Karai is good, while Raphael thinks she's pure evil, while Michelangelo and Donatello are perplexed by who she even is. The fight gathers The Kraang's attention, and they attempt to subdue them. Karai makes the fight worse by unleashing a monster containing DNA from assorted animals. She then grabs a broken Kraang droid, abandons the Turtles, and brings it to her father to possibly convince him that The Kraang are worthy of looking into. Also, Baxter Stockman claims that he could work with the technology efficiently. The Shredder's mindset has successfully been changed, and he asks her to find out everything she can about The Kraang. 

In Enemy of My Enemy, Karai appears out of nowhere while the turtles are surveying the T.C.R.I. building. She immediately pulls out her katana and attacks Leo. Raph, Donnie, and Mikey all join in to fight her, but she quickly begins to outmatch them. She mentions that she overheard Donnie talking about The Kraang. At first, they don't want to let her in on the situation, but Raph lets lose that they are trying to stop a full-scale invasion. Suddenly, a flash of purple light comes from the T.C.R.I. building. A door opens on a side of the skyscraper, and a strange aircraft floats out, resembling a jellyfish, with a round body, three short, stubby tentacles and a single purple "eye". It is piloted by two Kraang brains, who quickly spot the turtles and Karai and move in to attack. The ninjas run across the rooftops, narrowly avoiding the ship's energy beam weapon. Karai ducks into an alley, while the ship pursues the turtles. Leo runs out to draw the ship's fire, while the other three make it to the sewers. Leo joins them and they watch the ship from a storm drain. The ship activates a cloaking device and vanishes to avoid detection by a passing Police helicopter. Karai returns to The Foot's headquarters and reports what she has seen to The Shredder. He ignores the threat that The Kraang pose, and tells her that they will soon receive a shipment of new weapons that will end their war with the turtles and Splinter.

Later, after a brief spar with Leonardo, she tells him that she wants to help them fight The Kraang. She is afraid that Shredder's stubborn refusal to see anything beyond his vengeance will get them all into big trouble. She asks him if they could work together, but Leo refuses and leaves. Later, The ship chases the Shellraiser down a street. Leo asks Mikey for an escape route and Mikey accidentally leads them into a dead end. The ship starts to blast through the Shellraiser, but they turtles narrowly avoid definite annihilation by backing out of the alley quickly and hitting the streets once again. Karai then jumps out of nowhere onto the top of the ship and effortlessly, begins slamming her katana on it. Leo decides to help her out, and he jumps into The Shell Cycle and chases her and the ship down on his own. When Karai falls off of the ship, Leo saves her at the last possible second. He then brings her into The Shellraiser. When Raph instantaneously objects to her presence, Leo tells him to hear her out. Karai tells them that they need her help and that the only way to take that ship down is with a missile launcher from the Foot shipment, which she tells them will be arriving at the docks the next evening. All of the turtles except Leo) are suspicious of her, so Karai says that she will get the missile launcher herself. Leo agrees that, if she gets the weapon, the turtles will team up with her to stop the ship. Secretly, however, the turtles devise a plan to eliminate The Shredder, as he would never be expecting them to show up there. As Karai retrieves the missile launcher, she spots the turtles on top of a shipping container near the docks. She pushes her adoptive father out of the way so that the electric grenade (which Donnie invented) electrocutes the Foot Soldiers and the man with the diamond eye (who was the one who brought the shipment). Karai then fires at the turtles, knocking them off the container. Leo makes it to the box of missile launchers, but is confronted by Karai. She tells him that she feels betrayed and that he is just as short-sighted and obsessed as The Shredder. She then reveals to Leo that The Shredder is her father (apparently). Leo is shocked by this news. Karai says that the deal is off and attacks Leo. After a short fight the ship returns and Karai hides from it. When she emerges, she finds that Leo has already taken a missile launcher and gone after the ship. Meanwhile, the other three turtles are fighting against The Shredder, but are miserably losing (much like the prior time). Meanwhile, Leo takes aim and fires a missile at the ship. The missile hits it's target and the ship crashes into the wharf, knocking Shredder into the ocean. Karai dives in after him, while the turtles retreat. Karai helps The Shredder out of the water. He thanks her, and tells her that he has found a pet for her and holds up a Kraang, which he has captured.

In Karai's Vendetta, Shredder's interrogation of the captive Kraang proves futile, as it does nothing but senseless squealing. Karai suggests putting the Kraang into the limbless exo-suit they possess. Upon hearing it speaking relatively sensible english, the Kraang stated that they hunt the turtles because the latters protect April O'Neil, who is crucial to their plans. Thus, Shredder dispatches Karai to capture April to draw the turtles out. She meets April under the alias "Harmony". She then reveals her identity when trying to feed April turtle soup. April forces Karai to pursue her on foot, but she traps herself in an alley. She pulls out her weapon and Karai compliments on it before disarming her. April tries attacking her directly, but Karai dodges her attacks and starts attacking her, easily overpowering her. She knocks her into the street and demands to know why she's so important as she continues attacking her. April is able to defend herself and provide her own questions. However, just when Karai has her pinned, she mentions losing her mother, causing Karai to hesitate which distracts her long enough to throw her down the subway stairs and escape.

In [[Showdown, Part 1}]], Karai leads a squad of foot soldiers into the sewers, where they abduct April after she is led away from the Turtles' lair by her brainwashed father, Kirby O'Neil.

Later in Booyaka-Showdown, Part 2, Karai intervenes in Shredder and Splinter's battle just as Splinter is about to kill her adopted father. Prior to this, Shredder had revealed to Splinter that after their last battle, fifteen years ago, he had taken Splinter's infant daughter, Miwa, and raised her as his own. Splinter recognizes Karai as Miwa during their brief confrontation, and when Shredder informs her that the rat is Hamato Yoshi, Karai accuses Splinter of murdering her mother, another lie told to her by the Shredder. She attacks Splinter, but her true father refuses to engage her in combat, and leaves.

In Follow the Leader, Karai is set upon by robotic Foot ninja, which were designed by the Kraang to adapt to their opponent's moves. When she was at the robots' mercy, Shredder intervenes. Karai asks if he was going to let the Foot Bots kill, to which he doesn't answer. Shredder then says he's leaving for Japan on business and warned her not to make any moves against the Turtles. But she disobeys and captures Leo, taking him to Bradford's dojo. When his brothers rescue him and escape, Karai catches up with Leo and nearly pushes him off of a building. However, Leo avoids falling by sticking his katana into the ledge, and he jumps behind Karai, catching her unaware. She falls to the ground, where Leo holds a sword to her head and tells her that Shredder is lying to her and that Splinter did not kill her mother, while also ordering her to stay away from his brothers and keep the feud between her and him. As he leaves, he gives one last plea for Karai to believe him about Splinter.

In Mikey Gets Shellacne, Karai dispatches Dogpound and Fishface to find Baxter Stockman so he can maintain her Foot Bots. She later finds her two subordinates, Dogpound mutated into Rahzar, in Baxter's old lab and tells the good doctor that he works for her and the Shredder.

In Target: April O'Neil, Shredder is very unhappy that Karai disobeyed him and sought out the Turtles. Karai blamed her failure on the Foot Bots but insists that the Kraang are improving them. However, Shredder orders to avoid any deals with the Kraang until his return. Again, Karai disobeys and goes to the Kraang, who are building a robotic replica of Bradford's old human form. She then decides on a test run on April. Though the Kraang become startled, they permit the test. Karai eventually confronts April and Don with a squad of Foot Bots. While her robots distracted Donnie, Karai engaged April, bragging that her years of training make her superior, only to be struck in the head by April's tessen. Despite this, she is able to incapacitate April, only for Donnie to come to her defense and knock her down instead. Just then, Robo-Bradford arrives and seizes April, it disobeys Karai's orders to kill her as it obeys its Kraang programming to kidnap her for the Kraang. Karai stopped it from taking off with her rival, causing the robot to turn on her. When the other Turtles arrive on the scene, Leo assist April against Karai, forcing her escape via smoke bomb.

In The Manhattan Project, Part 1 Leonardo tells her that Splinter is her real father, but she dose not believe him. After the defeat of Tiger Claw, Raph then wonders where Karai is now while April still cannot believe that she is Splinter's very daughter. Splinter stated that one day Karai may indeed accept the truth, but that is her decision to make and her's alone. Unbeknownst to all of them, Karai is secretly hiding behind another billboard not too far away from them. She hears every single thing that they said. Judging by her several facial expressions) not only does she find herself in a difficult dilemma, but finally seems to start questioning Herself.

In The Wrath of Tiger Claw Karai was looking at a photo of her mother when The Shredder asked her what was bothering her, she then told him she wanted the truth about her mother, Shredder then told her that Hamato Yoshi killed her. All is Interrupted when Tiger Claw returns, Karai questions how he possibly could've survived, Tiger Claw explains how he escaped and all the dimensions and battles he's been through and how he wants revenge on everyone who made him go through it. Shredder then tells him that he will grant his wish and orders Karai to go with him and destroy the turtles and Splinter, while running through the rooftops and bantering she questions Tiger Claw on what his plan is. Tiger Claw then tells her that she is with him because she knows where the turtles hang out and who there friends are, they head off too Murakami's restaurant where they question him for information Karai sees how scared he is and states "there's no honor in this" and leaves while Tiger Claw trashes the place and gains information on the turtle's friends. They then go to the movie theater and find Casey, April and Irma there, April senses them and then they split up to separate them. Karai catches up with April and as April prepares for a fight Karai tells her she just wants to talk, so Karai tells her about how the Shredder lied to her and that now she believes Splinter is her father right when Donatello and Leonardo come in and she tells them the same. Leo then decides to take her to the lair and when they do Raph is there and states how much of he doesn't want her there, during the argument Karai activates a tracking device for Tiger Claw to follow. Splinter enters the room and stops the argument and then sees Karai, he then tells her too come with him as he has something to show her. He then shows her the pictures of himself, Tang Shen and baby Miwa all together, and then she finally realizes the truth and tells them she tricked them into taking her into the lair and that Tiger Claw is coming, she then has a plan to lure Tiger Claw away from the lair and then leaves with the turtles. Still in the sewers Karai doesn't know where to go but Michelangelo does, they all go to a butcher shop where the turtles take on Tiger Claw. However, he proves too strong for them and then offers Karai the chance to finish them off. She instead attacks him but is unfortunately knocked out by him and taken hostage, Tiger Claw threatened to kill her if the turtles didn't let him go, so they let him go and he gets away with Karai. Later at Shredders hideout Karai demands the truth from him and Shredder finally admits that Splinter is her true father. He then has her locked up.

Personality

When Karai makes her first appearance in the episode New Girl in Town, she is portrayed as quite a rebellious teenager and expert Martial Artist, who stirs up trouble at times.

Karai is typically portrayed to be an evil character, but one that always has conflicted emotions. She revels in the freedom that The Foot Clan gives her, and she often takes advantage of it at every turn, choosing to toy with/fight the Turtles. However, she still does operate on a bit more complex code than her "father" or clan does, and, at one point, she seemed to have a bit of a greater concern over the community around them (and the Turtles) than her father did. For example, she once tried to persuade her father to look into the Kraang and possibly become allies with them to use their advanced Tech (The Shredder didn't listen to her at first, but then did after quite a long while). There are also several times that she has actually tried to aid the Turtles in their constant battles against The Kraang, but, at the same time, she also has tried to kill our heroes by leaving him to deal with a violent aberration mutant that she carelessly, yet purposely created - and she has tried to kill them many a time on her own as well....She was, at first, seemingly rather intolerant of the grudge her father has for both Hamato Yoshi and the Turtles, but she later turned out to be nearly as vindictive as her adoptive "father" is, especially after she comes to face to face with Splinter (in "Booyaka-Showdown, Part 2", when she finds him engaging in a mortal duel with the Shredder) and this ultimately brings out the true emotions that she had concealed for years upon years. This also ended up causing her to get enraged when she came across Splinter battling (and slashing one of his shoulders). Also, because of this, she often chooses to vent her anger and jealousy on those who are undeserving (such as April or Leonardo). Her rebellion has now made her dangerously unpredictable with all four of the Turtles....

Karai is quite intrepid, and she clearly has enough bravery to disobey her 'adoptive' father (such as when he leaves on a journey for Japan and orders her to temporarily take his place). However, she is equally afraid of him sometimes (especially when he threatens her). However, she still cares for him as her "makeshift father", and would be more than willing to protect him if the situation calls.

All we need to do is sneak in and help ourselves. And why would I trap you? You're the only ones who know what The Kraang are up to."

Appearance

She is shown to be slightly taller than Leo (and April). Karai has dark black hair that is dyed blonde in the back, and two notable strands of her hair falls over her ears. She wears several black earrings and red eyeliner on the top of her eyelids, which have brown irises. Karai always wears silver armor, black material worn under her armor, traditional Japanese shoes, and a purple belt with a design on it (alot like the Shredder's). Her primary weapon of choice is a Tantō (a short yet sharp Japanese blade). She does have a civilian outfit as well, with a punk-esque design with worn jeans and a leather biker jacket with metal studs....

Relationships

Shredder

Karai's current relationship with her father is actually quite complicated. She seems to fear The Shredder at certain times, just like Bradford and Xever do, yet she obeys him, but she doesn't appear to respect him as much. It is possible that she wants him to respect her equally, such as when she mentions The Kraang and shows him the droid she had picked up, attempting to intrigue him somehow. In "Enemy of My Enemy", just a little more insight is given into Karai's relationship with her false father. Karai saves him a total of two times in this very episode. She tackles him out of the way to prevent him from getting zapped by an electro-grenade and bravely jumps into the sea to save her father from drowning towards the end of the episode.This proves that Karai truly loves Shredder as her father despite constantly disobeying his orders. Although Shredder feelings for Karai are unclear.

Leonardo

Leonardo is the first of the Turtles that Karai meets. While she attacks and fights with him often, she never does him any serious harm and just enjoys sparring with a worthy opponent. Leonardo, in turn, was both confused by and attracted to Karai (as shown in "New Girl In Town"). She is dangerous, but Leo believed that there was some good in her but she betrayed him. She seems to be deceitful and manipulative in The Alien Agenda, using Leo's feelings for her against him, especially in his time of need. In Enemy of My Enemy, she returns, seeking information about the Kraang from the turtles. This time, instead of wanting to fight the turtles, she decides to make a truce with the turtles in order to defeat the Kraang ship. She goes against the Shredder's orders because she knows they'll all die if they don't set aside their differences and take down the ship. At first, the turtles, mainly Leo, are very skeptical of her and decline her request for a truce, but after she leads it away from the Shellraiser, they comply. Because Leo saved her and allowed her to speak to all of Turtles, Karai develops some friendship for him. However, because he and his brothers tried to attack her father, the truce was called off and her trust in him was left now uncertain. Now she's vengeful towards the turtles and is willing to do whatever it takes to take them down. It was revealed in the Season 1 finale that Karai is Splinter's lost daughter (Miwa), who was raised by the Shredder. Leo seems more aggravated with Karai as she wants to hurt him and his loved ones more often, he tells her that her vendetta is with him not his family. In Follow The Leader Splinter told Leo, Karai is his daughter.

Raphael, Donatello and Michelangelo

Raphael is the second of the Turtles that Karai meets, and Raph is the first to find out about Leonardo's "friendship" with her. Unlike his brother, Raphael immediately distrusts her. He tries to warn Leo that she is the enemy and not to trust her. Raph came up with the idea of setting a trap for Shredder and (like the rest of his brothers) attempted to assassinate the Shredder. He still does not trust her when she wants to help defeat the Kraang. Donatello does not know too much about her mainly because Leo never mentioned her until after they revealed her in The Worldwide Genome Project headquarters. Based on Donnie’s observations of her, he does not like her because of her need to cause trouble. He is wary of Karai's tactics and does not trust her at all, not even when she offerd to help him and his brothers fight the Kraang. Donnie also was a part of the attempted assassination of the Shredder. Michelangelo also did not trust her and was surprised that Leo trusted her. When she wanted to help fight the Kraang, Mikey was wary of her. Mikey also participated in the attempted assassination. They see her as an enemy working for the Foot, but she sees them more as play toys for her amusement. In Booyaka-Showdown, it is revealed that Karai is Splinter's daughter, Miwa, who the Shredder took and raised her as his own daughter after the events of their final battle. When Splinter told the turtles about this, they were all shocked and Mikey questions about Karai being their "sister".

Chris Bradford and Xever

Relationship is vastly unknown for the most part, but Karai did seem to stand up for both Bradford and Xever in a way when she told the Shredder that his own men got turned into hideous freaks when she wanted Shredder to try and help her figure out what was going on with the Kraang.

April O'Neil

April is the first female human that she has met in the whole series. Based on their brief encounter in "Karai's Vendetta", they seem to have quite a lot in common. They both know how to speak Japanese, they both know how to drive a motorized vehicle, they're both kunoichis (except Karai has better Martial Art skills), they are both the romantic "interests" of one of four Turtles, and both of their biological fathers have been mutated into animals (both of which are mammals - A rat and a bat). They seem to become enemies in "Karai's Vendetta" (though Karai does seem to have a regretful expression on her face not very long after she attacks April). It is also suggested that Karai dislikes April somewhat and is jealous of her, due to the fact that she is very special and important to the Kraang and Splinter (a value that Karai doesn't think she has). At the very end of this episode, however, Karai appears to show signs of empathy and feeling slightly sorry for April when the other girl mentions that she lost her mother. If they weren't on different sides, it's likely that the two could be very good friends. However, their current views of each other are likely to change once Karai truly finds out and accepts that Splinter is her biological father.

Tang Shen

Karai is Tang Shen's daughter, along with Master Splinter's. When she was an infant, her mother perished in the house set fire to by the Shredder and was taken in by him. He then raised Karai as his own child and fed her countless lies about how her mother died and who committed the act. Karai has known this false truth for a big portion of her life, but when Splinter showed up in Shredder's hideout in "Booyaka-Showdown", her true feelings on the situation are exacerbated even more - and she now desperately hopes to avenge her own mother's death by killing her true father.

Even though she doesn't know what her mother was actually like, she carries a torn-off, dilapidated photo of her mother around with her. It is likely that this was part of a grander, family photo like the one Splinter has in the lair, but the Shredder probably ripped Tang Shen's part off to conceal his own lie.

Splinter

Karai is none other than Splinter's biological daughter. In the episode "Booyaka-Showdown Part 2", Splinter discovers this after the Shredder reveals to him that he took his daughter, Miwa, away and raised her as his very own child. When Karai soon shows up, he is then able to turn Splinter's own daughter against him by using what he had formerly told her about whom killed her mother, Tang Shen. She then tries to fight Yoshi, but her manages to avoid her attacks and escapes. She then demands to know why he won't fight with her and calls him a coward. He then leaves, heartbroken at what the Shredder has done to his daughter....In "Follow The Leader", she demonstrates how truly spiteful and vengeful she has now become towards him. She hates him to the point where she wanted to kill the Turtles before his very eyes and ruin his life in so many more ways. When she successfully tranquilizes Splinter in "The Manhattan Project, Part 1", she seems to view this as a big victory and she also even appears to draw some sadistic pleasure from doing this.

It is very clear that Splinter knows that his daughter is fully alive, active, and working alongside the Shredder, but it's still unclear if Karai knowing the utter truth will change her opinion of the Shredder and her take on life as she knows it. In The Manhattan project, part 2, she over hears splinter talking to the team about him being her biological father and whether if she will figure it out and accept it is her decision. She then has a guilty expression on her face suggesting that she's starting to question herself and everything else.

Trivia 

  • In "Booyaka-Showdown, Part 2", it is revealed that she is in fact Splinter's lost daughter, Miwa. She was presumed dead after Splinter and Shredder's duel and the destruction of Splinter's home. In reality, she was found by the Shredder and raised as his daughter.
  • The false name that Karai gave April in Karai's Vendetta, Harmony, can be written in Japanese as "Miwa".
  • In The Wrath of Tiger Claw Karai finally learns and accepts the truth of Master Splinter being her real father.
