Karai is Shredder’s most trusted advisor and commander.  She is an expert ninja, a true prodigy, and an excellent addition to an evil army.  While she follows her Master’s orders in battle, she is not always happy to do so. Shredder is sure of his evil agenda, and will crush anyone who gets in his way, but Karai struggles with morality and whether or not the methods employed are actually necessary to get the job done.  This creates opportunity for her to team up with the Teenage Mutant Ninja Turtles, especially Leonardo (who she views as a kindred spirit), and shows her struggling with allegiances. Karai is a deadly warrior, but inside is a kind heart waiting to be released.


The first appearance of the character “Karai” came in the comics in 1992, eight years after the turtles had started their battle against the Shredder.  The struggle with their arch-nemesis came to an end with Shredder’s death and the Foot Clan left in disarray.  In that moment of weakness, Karai appeared and unified the organization.  Having served as the leader of the Japan branch, she was an obvious choice to take over, and had the skills necessary to be the new master.  A departure from Oroku Saki, Karai offered the turtles a truce upon arrival, which they tentatively accepted, ending the war with the Foot once and for all.

 TMNT Karai Biography Comic Incarnation 2

While Karai did not appear until 1992, another female ninja (often considered to be Karai’s predecessor) appeared prior to that in the 1987 animated series.  Lotus Blossom was hired by Krang to defeat the turtles, and easily defeated Shredder.  However, she could only eke out a draw against Leonardo, and eventually turned on Krang to join the turtles.  Her personality, actions, abilities, and relationships were very similar to those Karai would later possess, and so Lotus is seen by some as the inspiration for the future female ninja.


TMNT Karai Biography 2002 SeriesKarai returned in the 2003 animated series as Shredder’s adopted daughter.  Oroku Saki raised and taught Karai after her parents abandoned her, so she became his right hand and enemy of the Teenage Mutant Ninja Turtles.  However, a new wrinkle was added.  Unlike her first incarnation, where she suggested an alliance with the turtles, she began as their enemy – completely willing to destroy them whenever her father commanded.  However, she was torn between her honor and obeying Shredder, which often led her to assist the turtles.  Despite her upbringing, this Karai understood right from wrong at her core, and adjusted her actions accordingly.  She even had some sort of unspoken relationship with Leonardo.  Eventually, Ch’rell was killed, and Karai took up the mantle of Shredder in rage.  She became a true enemy of the turtles for some time and master of the Foot Clan (as in the comics).  When Ch’rell was revived, Karai was his first target.  She survived his revenge, and eventually left New York to train, becoming an ally of the heroes in later reappearances.


Karai was also featured prominently in the 2012 series.  She was once again the adopted daughter of Oroku Saki (though her backstory and true lineage may come into play at some point).  She is a fierce ninja, much better than any of the Teenage Mutant Ninja Turtles, although Leonardo proves to be somewhat of a match for her.  The unspoken relationship between those two returned, though Leonardo’s feelings were obvious from the beginning, while Karai’s true intentions were a mystery.  Karai tried to form an alliance with the turtles, but this time they betrayed her, creating an enemy and guaranteeing future conflict.

TMNT Karai Biography Nickelodeon Incarnation

Karai’s only appearance in the films was in TMNT (2007).  As an unofficial sequel to the first three films, Shredder is dead, and Karai has since taken charge of the Foot Clan.  Her personality and characteristics were not developed, so whether she had any of her former incarnations was never discussed (nor was it relevant to the plot of that particular film).  However, what was evident was the fact that she had no intention of continuing the war with the turtles.  Like her comic book counterpart, this Karai was not interested in the mutants, and was instead was trying to mold the Foot into a strong organization again.





Karai was an interesting character that needed to happen– just not necessarily in this particular way.  By the time she came about in 1992, fans already had eight years of radical dude turtles kicking evil butt.  While the comic was targeted at boys, it’s not beyond belief that the core audience would have responded well to a female ninja.  Her continued inclusion in future incarnations is proof of just that.  But why was she human?  Was it simply out of convenience for the story at that point?  While Venus de Milo was a failed attempt at a female ninja, the idea of Karai being a mutant almost seems like it would have been better for stories (and romance).  If Karai was Shredder’s attempt at a mutant ninja, there could have been some fierce battles between four mutant turtles and (for instance) a devious mutant fox.  So while Karai was important and always will be integral to the TMNT universe, it doesn’t seem clear what the motivation for her creation really was.


Karai is also the type of character that everyone loves.  There’s something about a villain with a kind heart, honor code, and moral turpitude that plays well with audiences.  For most, it probably has to do with the desire to see a transformation from evil to good.  Because the character is always on the verge of acting like one of the good guys, there’s hope that he or she will just take the plunge, see the error of his or her ways, and move into the hero’s command center forever.  Karai is that villain, and that makes her very likable.  Her personality suggests she should be with the turtles instead of against them.  She also poses a very interesting example of a complex philosophical question: Nature versus Nurture.  Shredder’s influence is a prime of example of how nurture can lead down a bad road.  On the other hand, there is her honor, which could very well be her true nature shining through.  If she were real, she would be the ultimate case study for anthropologists, psychologists, and philosophers for years.

Since the very beginning, there was a clear connection between Karai and Leonardo, which was amplified in 2003, and taken off the charts in 2012.  Even Lotus Blossom gravitated to Leo more than any of the others.  There is a very vocal following that wants the two of them in some sort of relationship.  But, it doesn’t seem likely that that will ever happen, mainly because Karai’s role in the story and the power of the honor versus family dichotomy are too useful as tools to resolve in a “happily ever after” way.  As such, Leo and Karai will probably be stuck as rivals and either friends or enemies for all eternity.  Love will just have to find a way into the world through a different couple.


Like many characters in the TMNT universe, Karai has often been the victim of minimal history for future character development.  In other words, what happened to her as a child has never been discussed in much detail.  While it’s always made clear what her relationship to Shredder is in each incarnation, exactly what happened to warrant her devotion is never quite clear. The 2012 series looks to be resolving that, although it’s not quite clear how at this time.  There have been many hints about her parents and undertones suggesting that she has a much bigger role to play in the lives of other characters.  If that development actually bears fruit, then the newest version of Karai could be the most fully developed.  She would have a complete story, and the audience could understand her motivations, adding depth to her choices.


Karai is a unique individual in the TMNT universe, and her importance will never be usurped by another character.  Her loyalty often conflicts with her morality, leaving her searching for black-and-white answers in a world drenched in shades of grey.  Whether she’s a hero or villain, Karai will always have supporters, and she will continue to serve as a ninja for the Foot.  What that choice will ultimately bring, only time will tell.

An alternate spelling of “Karai” is “Kurai”, which means “dark” in Japanese, explaining more of the depth of her character.


In Brazil, “Karai” sounds like a curse word, so her name is spelled “Karrai”.


The 2003 series was the first time Karai has shown what could be considered romantic feelings for someone other than Leonardo.  She ended up running away with Dr. Chaplin of the Foot Tech Division, and is with him until the vey end of the series.


If Lotus Blossom could defeat Shredder easily in the 1987 series, but could only duel Leonardo to a draw, then Leonardo should have been able to defeat Shredder single-handedly, making most of occurrences of that series completely moot.
