Splinter, often referred to as Master Splinter or Sensei by his students/sons, is a fictional character from Teenage Mutant Ninja Turtles comics and all related media.^[1][2] A mutant rat, he is the grave and stoic sage of the Turtles, their ninjutsu and martial arts instructor, and their adoptive father. The character was originally a parody of the Marvel Comics character Stick.

In both the original comics and the live-action movies, Splinter is a pet of a ninja named Hamato Yoshi in Japan, and uniquely intelligent for his species. Yoshi becomes embroiled in a deadly dispute with a fellow ninja by the name of Oroku Nagi and is eventually murdered in turn by Nagi's brother, Oroku Saki, as revenge for his brother's death. However, in the 1990 film and 2003 TV series Nagi is removed entirely. Additionally, in the 1990 film, Splinter escapes from his cage during the murder, and attacks Saki, clawing at his face. Saki, in turn, slices his ear off. It is suggested that this mutilation is the reason Saki took the Shredder disguise to hide the scars. In contrast, in the 2003 TMNT cartoon series, it was Hun's face which Splinter clawed.

Without a home, Splinter is forced to run away and live in New York City's sewers. Due to a traffic accident, four baby turtles and a canister of mutagenic ooze are sent down into the sewer. The canister mutates both Splinter and the turtles; it also enhances the former's already sophisticated intellect. Splinter names the four turtles Leonardo, Donatello, Raphael, and Michelangelo (after a book on Renaissance artists that he found in a storm drain) and trains them in the arts of ninjutsu so that they can avenge his dead master while raising them as his own sons, as well as educating them.

In the 2003 TMNT cartoon, he possesses a significant reputation as a ninja master; in a multi-part episode, he is revealed to be a champion of the Battle Nexus, a multi-dimension-spanning contest where the greatest combatants of various dimensions come together to fight each other for the title of Battle Nexus Champion. When the Turtles learn of the Battle Nexus, they participate as well, resulting in Splinter forfeiting when called upon to fight Michelangelo, as he wishes to allow his sons the opportunity to fight where he succeeded in the past.

In the episode "Tempus Fugit", Splinter and the Turtles, who time-traveled into the future, are sent back to the present time, but the villain, Viral, blasts Splinter with a decompiler ray that scatters his bits all over the internet. While Splinter was not seen much in the "Back to the Sewers" season, the focus of those episodes is the Turtles' efforts to find Splinter's data bits by traveling all over cyberspace. Splinter is restored in the final episode and helps defeat the Cyber Shredder.

In Teenage Mutant Ninja Turtles: Mutant Mayhem, much like the 2014 film, he is not Hamato Yoshi, nor is he connected to him in any way. But like the Mirage comics, he is exposed to mutagen in the sewer and not experimented on. He was a street rat that hated humans and went into the sewers to scavenge for food. But instead of food, Splinter found four baby turtles that were covered in green ooze. Splinter rescued the Turtles and got some of the ooze on him, transforming him and the Turtles. After a bad encounter with humans, Splinter decided to learn ninjutsu from online videos and Jackie Chan movies and teach it to his sons.

In the 1987 TMNT cartoon, Splinter and Yoshi are the same person. He is a martial art instructor for the Foot Clan in Japan, and also has a passion for Renaissance art. Yoshi is framed by his rival, Oroku Saki, for trying to murder their common dojo master. Unable to prove his innocence and expelled from the Foot Clan, Splinter moves to New York City, where he lives as a hermit in its sewers and befriends the rats. One day, he comes across four baby turtles which were accidentally dropped by a boy through a sewer grate. Splinter keeps them as pets and treats them like his children. When he finds the turtles near some broken barrels that are oozing glowing pink, later retconned to green, chemical liquid, he tries to clean them with his bare hands. As a result, they are all affected by the leaking chemical, which is a mutagen. The mutagen combines the DNA of living beings who have been in contact. Thus, the turtles, being in a pet store with people touching them, turn into young humanoid turtles. Yoshi, having been in contact with sewer rats, becomes a humanoid rat. Although, Master Splinter did get the chance to be human again in the episode "Splinter No More", but realizes he prefers being with the turtles and had no place as a human anymore.

Yoshi raises the turtles by himself and gives them the names of his favorite Renaissance artists: Leonardo, Donatello, Raphael, and Michelangelo. Yoshi is given the nickname "Splinter", due to his proficiency at breaking wooden boards, and he teaches them the art of ninjutsu in order to protect themselves. Like many real-life ninja masters, he has a strong sense of honor and follows very strict rules which all four of his students adopt. Master Splinter always has a wise quote or speech for the turtles and often steps in with his ninja skills when the turtles are caught in a, seemingly inescapable, predicament.

Master Splinter does not have a father/son relationship with the turtles, as suggested in other versions, but more of a teacher/student bond. Despite not having that father/son relationship with the turtles, Splinter, in the episode "The Old Switcheroo", shows a glimpse of fatherly concern for Leonardo when he is injured by one of Donatello's contraptions. In addition, in Turtles Forever the old 1987 series turtles are surprised when the 2003 series turtles call Splinter "father". However, in the movie, the 2003 series Leonardo comments that it feels right to be with the 1987 Splinter regardless of the differences between the two worlds. Splinter's assurances that he feels the same, coupled with his comment that Leonardo and his brothers will always be welcome there, helps Leonardo see the common similarities between the teams, regardless of their different styles and methods.

In the final episode, "Divide and Conquer", Splinter explains to the turtles after they defeated Dregg that they are no longer his students but his equals and they have finally become ninja masters.^[3]

The 1990 live action concert tour entitled "Coming Out of Their Shells", saw Splinter described as the rat owned by Hamato Yoshi mutated to a humanoid form, rather than Yoshi himself mutated into a ratlike body, bringing him more in line with the original Mirage Comics incarnation as well as that of the then recently released feature film, which also followed the Mirage origin. In the concert events, he is still the Turtles' mentor in the martial arts, as well as encouraging their musical pursuits, and sings the track Skipping Stones as a solo ballad. He encourages the Turtles as they deal with the Shredder's plot to steal all music in the world, though he does not physically join the battles against Shredder or his foot soldiers. Peter Reneday reprises his role as the voice of Splinter with the exception of the song Skipping Stones, though both the show's Pay per view and VHS cast lists both leave him uncredited.

Archie Comics published the Teenage Mutant Ninja Turtles Adventures which began as an adaptation of the 1987 TV series in comic form, though the series eventually deviated from this and began telling its own stories with little to no connection to the original cartoon, effectively becoming a separate continuity. In the comic, they maintained Splinter's human background even when they started publishing original storylines.

In the 2012 series, Splinter is again introduced as Hamato Yoshi, voiced by Hoon Lee. His relationship with Oroku Saki is mostly intact, with the Hamato and Foot Clans later revealed to have had a long-term conflict with each other. Despite being raised as brothers, both Yoshi and Saki become rivals due to their affection for Tang Shen, and Saki wishes to discredit Yoshi in front of her. Yoshi loses his temper by mistake and the altercation forever destroyed their relationship, culminating with Saki learning of his true heritage and starting a battle that burns down the Hamato Clan monastery, indirectly killing Shen and, seemingly, Shen and Yoshi's daughter, Miwa.

After moving to New York City, Yoshi has just purchased four pet turtles when he stumbles upon an exchange in an alley between two Kraang droids. Seeking to silence Yoshi before he can share what he has seen, a fight ensues and the canister the droids have been carrying smashes open, splashing both Yoshi and his turtles with a mutagen. As the result of stepping on the tail of a black rat upon entering an alley, Yoshi mutates while the Turtles take on human characteristics. Realizing he can no longer live a normal life, he retreats to the New York sewers where he raises his pets as sons and teaches them ninjutsu. Compared to his earlier counterparts, he is very strict in this series.

Splinter's sons, along with their new friend April O'Neil, soon become involved in the conflict with both of Splinter's old enemies, the Shredder and the Kraang. Reluctantly allowing the group to get involved, Splinter appoints Leonardo as their leader and continues to offer counsel and lessons as they engage various foes. Recognizing great sensitivity in April, he begins training her as a kunoichi and comes to regard her with a fatherly fondness. Splinter ventures from his lair on only two occasions. The first is when he falls under the control of the Rat King, who attempts to persuade him to forsake his humanity and embrace the life of a rat. Splinter eventually breaks free with the Turtles' help and defeats the Rat King. The second is when Shredder kidnaps April and lures Splinter to his stronghold for a final confrontation. Splinter overpowers Shredder's men and engages his old foe. Shredder reveals that Splinter's daughter, Miwa, had not died and that Shredder had taken her and raised her as his own. Splinter nearly defeats Shredder, only to be attacked by Miwa; Miwa, whose name is now Karai, has been taught, by Shredder, that Splinter is responsible for her mother's death.

As the second season progresses, Splinter tells the turtles about his true relationship with Karai. He is eventually able to convince Karai of the truth about their past, but she subsequently mutates into a snake-like being when Shredder's plan for revenge backfires. Later, Earth is invaded by the Kraang and, in the ensuing battle, much of Splinter's lair is destroyed before Splinter is able to defeat Kraang Sub-Prime. Splinter then leaves the lair to find his missing sons. Splinter again engages Shredder in battle and, seemingly victorious, Splinter prepares to reunite with his sons, April, and Casey Jones, only to be attacked from behind by Shredder and thrown into a sewer drain. He is rescued from drowning by Karai and left in an area of the sewer to recover.

At the end of the 3rd season, Splinter asks Shredder for a truce to stop the alien Triceratons. Shredder agrees but at the end of the battle, Shredder kills Splinter. The turtles hold him one last time before they, Casey and April flee with Fugitoid, as he arrives at the very last moment in a spaceship as Earth is sucked into a black hole.

When the turtles go through the time and fail to claim all the Black-Hole Generator pieces to help in the battle against the Triceratons and warn Splinter in time to stop Shredder from killing him. Splinter defeats Shredder, somewhat paralyzing him as Tiger Claw takes him away. When Shredder has himself infused with mutagen, he kidnaps Karai and demands her to come. Splinter fights Shredder along with the turtles, and the fight, leading up to rocky crevices and chasms below, Splinter and Shredder fall into a gaping chasm. Shredder's fall stops short as he lands on a rock outcrop as Splinter falls way down. He is still alive but his leg is broken. He sees the Rat King come toward him, seemingly surviving his fall down as well. Meanwhile, the turtles try to find him but Shredder goes after them. Splinter fights the Rat King but soon tumbles down and realizes that his fight with the Rat King was all a hallucination because of his fever he had developed in the chasm. He finds the skeletal remains of the Rat King and Donatello and Michelangelo find him, alive and well.

He later attempts to use his healing mantras to help April recover from the influence of the crystal fragment of the mystical Sol Star, and receives a vision of the ancient Aeons themselves but is overpowered by the form of a demonic Aeon. As April becomes possessed by the cosmic entity from within the Sol Star fragment, he attempts to reach her but is contained by April's exceptionally strong telekinesis. Regaining consciousness in the ransacked lair, he warns Donatello to be very careful as that being was not April. When April awakens from her ordeal, he expresses how impressed he is at how April was able to literally destroy her demons. He is once again killed by Shredder during a battle when Super Shredder impales him with his mutated claws and throws him off a rooftop. Splinter is buried at the O'Neil farmhouse. His spirit still gives his sons advice.

In season 5, Splinter's spirit briefly returns to the physical plane in order to help his family and friends after Shredder's henchmen accidentally open a portal to the nether world in an attempt to revive the Shredder and bring him back to life. After the crisis is stopped, Splinter has a final goodbye with his family and friends, and his spirit peacefully floats into the sky and returns to the afterlife once more.

The IDW Comics series, which began in 2011, presents a new origin for both Splinter and the Turtles. All five were originally test subjects at Baxter Stockman's bioengineering firm, Stockgen Corporation. When agents of the Foot Clan break into Stockgen and attempt to steal an alien mutagen, Splinter and the Turtles escape but are exposed to the mutagen in the process. While the element of Splinter being Hamato Yoshi is still present, Oroku Saki is now the Foot Clan's medieval leader, with Splinter and the Turtles being the reincarnations of Yoshi and his sons.

In the back-story, Hamato Yoshi was a member of the Foot Clan in feudal Japan. He is initially known for his unruly temper and lack of discipline. But with the help of his master, Masato, and his love, Tang Shen, he learned to control his temper and becomes a skilled warrior. His contemporary, Oroku Saki, seeks to make the Foot a clan to be feared. When Yoshi openly objects to the needless slaughter of a village connected to an assassination target, he and his family are declared traitors. Yoshi cannot save Tang Shen from being murdered but does save his sons. Yoshi raises and trains his sons for three years until Saki and the Foot find them. When his sons are executed before his eyes, Yoshi swears that he will destroy Oroku Saki before he, himself, falls under the blade.

The live-action 2014 reboot uses the test subject origin story, but Splinter is neither a reincarnation of Hamato Yoshi nor is he associated with him in any way. In fact, Yoshi is written out of the script entirely and Splinter simply learns ninjutsu from a discarded book after being mutated. In the movie, Splinter tells April that he does not remember his life before being in a laboratory, implying that there may be more to Splinter's character.

In Rise of the Teenage Mutant Ninja Turtles, voiced by Eric Bauza and Sander Argabrite (as a younger version of the character), Splinter is once again Hamato Yoshi, a descendant of the Hamato clan; however he is presented as ex-martial arts film star "Lou Jitsu" (taking inspiration from Jackie Chan and Bruce Lee) with an extremely relaxed attitude to life. He lives with his sons in their sewer lair and can be seen spending his time reliving his glory days by rewatching his movies as an action hero before he had been unexpectedly mutated into a rat. As the Turtles were intentionally mutated using Yoshi's DNA (revealed in 'Evil League of Mutants', and later shown in 'Goyles, Goyles, Goyles'), they are his biological sons in this iteration rather than adopted.

This adaptation's seemingly extreme deviation of Splinter's usual personality is eventually explained. Yoshi escaped his responsibility as a Hamato due to his mother being forced to leave him, nursing a growing resentment towards his clan until his departure. Later, a combination of being exploited by his former girlfriend to perform in gladiatorial combat and deep-seated worries the turtles were created to be soldiers gave Splinter an intense aversion to violence. Afraid that his sons would be put in harm's way he is less diligent in training them in ninjutsu, until he learns that the Foot Clan have been assembling the Shredder's armour, and he takes a more active role in preparing them for the danger his irresponsibility has placed them in. When they discover that their idol Lou Jitsu that they have been playfully emulating for years is in fact their sensei, they learn to appreciate their father more.

Splinter shows a great aptitude in using anything as a potential weapon, as shown in his films' he fights with Fish and Ladders in the episode 'Evil League of Mutants'.

Splinter's physical appearance remains fairly consistent in all incarnations of the character; he is portrayed as an elderly rat dressed in robes. The coloration of his fur varies depending on the incarnation. While brown fur is the most common depiction, he is sometimes depicted as having gray fur. In the original live-action movies, he is missing part of his right ear, which was cut off by Saki. In the 2012 series, Splinter is physically taller and younger than he was in past incarnations. He also has a more rat-like design along with distinctive body marks on his fur.

Splinter is portrayed as wise, intelligent, and a skilled "elderly martial arts master". He is nearly always calm. Even when angry, he refrains from raising his voice. He is the quintessential calm, all-knowing, and wise master of all martial arts. Also, Splinter has strong willpower as he doesn't give up without a fight. Also, in the 1987 series, Splinter can control his brain waves through his willpower.

Splinter cares for his adopted sons with fierce devotion, rescuing them in very critical moments in the series, such as when Shredder attempted to execute the four on a building, or when Bishop tried to literally tear them apart for science. He is furious when the Foot attempts to slay the Turtles with a robot Splinter and goes all the way to Japan after the four are kidnapped by the Tribunal. Splinter does go to the Turtles for help whenever he was in a tough spot, especially shown in the 1987 series episode "The Old Switcheroo" when an accident caused himself and Shredder to switch bodies as he went to them for help in getting back to his real body but had a hard time convincing them at first but they believed him when they heard his wise wisdom and that he didn't want to fight them as they worked together to set things right.

Despite his love for his sons, Splinter is fairly militant with them, especially when they are young and inexperienced. Splinter's main fear is that he and his family will one day be exposed to the outside world, as he is understandably protective. He disciplines the turtles when they become disobedient or unruly. His punishments include making them do back-flips repeatedly in the second live-action movie, or being sent to the Hashi, a form of punishment in the 2014 film by using chopsticks for balance. At times, Splinter does get physical with the Turtles whenever he gets mad with them or breaks up their siblings arguments, which led him to ground them, especially in 2012 series.

Splinter is not completely cut off from the pleasures of modern culture. Splinter is often depicted to be a fan of soap operas. This is stated in a few different incarnations but is most displayed in the 2003 series sixth season, where that hobby is mentioned several times. It is also mentioned in both the 2007 animated film and the 2012 series that he very much enjoys dessert, particularly Ice pops.

In the 2018 series, Splinter is displayed as somewhat irresponsible given his different history, spending most of his time eating and watching TV, although he occasionally shows the traits mentioned above.

In the 2023 film Teenage Mutant Ninja Turtles: Mutant Mayhem, he is shown to have an extreme hatred for the human race due to a perception that they were all out to hurt mutants, and as a result, he is overly protective of the Turtles. He is depicted as less of a traditional martial arts master and more of a worrisome single father figure, though he is still skilled in martial arts.
