The "origin of the TMNT" refers to a series of events present in most TMNT fictional universes, which ultimately culminate in the mutations of Splinter and the Ninja Turtles. Most versions are similar to outline of Splinter's tale in the first issue of the Mirage comics. Hamato Yoshi is slain by Oroku Saki and Splinter takes refuge in the sewers, where he discovers four baby turtles have been dropped by a young boy. One day Splinter returns to find the turtles crawling in a strange ooze, and their mutations into humanoid creatures begins.
Though most versions of the origin include these similar elements, many differences are present. Some delve deeper into the past, some have added minute details, and some have even altered the origins of the ooze or the identities of the characters. The most well known versions are those presented in the 1990 film and the 1987 cartoon series, although they are wholly irreconcilable with one another.
The Mirage version of the origin story lays out what would become the most common elements among the origin stories. It is recounted to the Turtles after their first successful battle.
Decades ago in Japan, there existed a ninja clan known as the Foot. Among the Foot's ranks was Hamato Yoshi, Splinter's original owner. From his cage, Splinter enjoyed mimicking Yoshi's movements, forming the basis for his knowledge of ninjutsu. Hamato Yoshi often clashed with a fellow member of the clan, Oroku Nagi, over the love of a woman named Tang Shen. When it became clear that Tang Shen loved only Yoshi, Nagi arrived at her home and savagely beat her. She was saved by Yoshi, who in a moment of rage, killed Nagi with his bare hands.
Knowing that the Foot Clan would not accept the murder of another member, Yoshi, Tang Shen and Splinter fled to New York City, where he founded a small martial arts school. Meanwhile, the Foot continued to train Nagi's younger brother, Oroku Saki. Fueled by a thirst for vengeance, Saki eventually became a high-ranking member of the organization, and was tasked with leading a branch of the Foot in New York. Once there, Saki adopted the mantel of the Shredder and led the clan to the highest ranks of the underworld, specializing in burglary, espionage, and assassination. Yet the entire time, Saki sought the opportunity to avenge his brother by slaying Hamato Yoshi.
One night Yoshi returned home to find his apartment ransacked, Tang Shen lying dead on the floor. Yoshi then saw the Shredder, who, revealing his identity as Oroku Saki, promptly killed Yoshi with his blades. Alone and heartbroken, Splinter escaped into the sewers, rummaging for food to survive.
In 1969, a young boy was carrying four baby turtles home from the pet shop. A blind man was crossing the road when a truck labeled "T.C.R.I." almost ran him down. A young man behind the boy with the Turtles ran out to save the blind man, bumping the boy with the turtles and knocking the jar from his hands. The jar broke when it landed in the gutter, and the Turtles were washed down a sewer drainage grate. As the truck swerved, the back doors flew open. A container of green glowing goo fell out and was subsequently washed down the drain with the baby turtles. The turtles landed safely, until the jar of goo fell beside them, coating them with its contents.
Moments later, Splinter came across the babies, gathering them into a can. He didn't realize he was coating himself with the green goo as he gathered them up. In very little time, Splinter and the turtles evolved and mutated into anthropomorphic beings with intelligence and emotion rivaling that of a human. Their mutation near completion, and educated, the rat named the Turtles after Renaissance artists - Leonardo, Donatello, Michaelangelo, Raphael. For the next fifteen years, Splinter raised and instructed the young turtles, his sons, in the martial arts in order avenge his master.
It is later revealed that the ooze was created by a group of benevolent aliens known as Utroms.
This origin is shared with the Image continuity and the Palladium source books.
The 1987 series deviates noticeably from the Mirage origin, completely removing Tang Shen and Oroku Nagi, and actually turning Hamato Yoshi into Splinter. In the series, Splinter relates his origin not to the Turtles, but to reporter April O'Neil.
As in all versions, Hamato Yoshi and Oroku Saki were members of the Foot Clan in 1960s Japan. Here the Foot Clan is portrayed as a peaceful organization, Yoshi himself a quiet man who loved Renaissance art. He had a long standing rivalry with Oroku Saki, who always planned to overthrow Yoshi as leader of the clan. When a master sensei arrived, Saki planted a dagger in Yoshi's dogi (fighting outfit), framing him in an assassination attempt. Dishonored, Yoshi was excommunicated by the Foot and fled to New York, where he lived homeless in the sewers.
In Japan, Saki turned the Foot into an army of crime, using their ninja skills for personal gain.
Far later in New York, a boy dropped a fishbowl of baby turtles down a storm drain. Yoshi found them and raised them as pets. One day he discovered the turtles crawling in a broken canister of glowing, purple ooze, and proceeded to clean them. Yoshi later realized that the ooze was a powerful mutagen, capable of turning any lifeform into the animal it last touched. As the turtles had last touched Yoshi, they became humanoid. Yoshi, however, had most recently been in contact with the rats, and thus became a half-man, half-rat mutant.
As ever, Yoshi named his sons after Renaissance artists and taught them ninjutsu, although in the cartoon it was for protection rather than vengeance. Seeing his capacity to break boards, the Turtles began to call their master Splinter, a name which he willingly adopted.
The alterations in this origin story were likely due censorship placed on death within children's cartoons. It also served to introduce the gimmick of the cartoon's mutagen; its property to merge animal and human DNA was unique to the series and was used extensively in the origin stories for various mutants in the toyline. Whereas most versions depict the mutagen as a product of T.C.R.I., here it is created by Krang, who allowed Saki to dump it in the sewers in hopes of killing Hamato Yoshi.
This origin is shared with the comic series Teenage Mutant Ninja Turtles Adventures, where it is again recounted to April.
The origin in the movie continuity is largely similar to the Mirage version. It does, however, contain some minor differences.
The character of Oroku Nagi is removed completely. And Hamato Yoshi's conflict is with Oroku Saki directly. The film shows that the two were bitter rivals in most things, but none more fiercely that for the love of a woman named Tang Shen. Shen persuaded Yoshi to flee with her to New York to avoid having to fight Saki for her hand in marriage (although not directly stated, this would have presumably been a fight to the death). However, they are followed by Oroku Saki, who kills them both in their home. Splinter leaps from his cage and permanently scars Saki's face. In retaliation, Saki slices off a portion of Splinter's ear. From there on the story remains primarily unchanged. Splinter discovers four baby turtles crawling in a puddle of ooze in the sewer. Their mutations begin and Splinter teaches them martial arts. However in this version, Splinter does not train the Turtles in ninjitsu with the direct intent of vengeance upon Saki, as he does in the Mirage comics, but rather for protection and as a way to remain unseen by a world he feels "could never understand" and "could never be ours".
Of note is that the ooze here is not a product of TCRI, but the similarly named TGRI. The company is revealed to be a normal scientific firm that created the ooze by accident, rather than an alien front like its comic book counterpart.
While it is never explicitly stated, it is likely that this origin is shared by the live action television series Ninja Turtles: The Next Mutation. The series never reveals a proper origin story, but certain visual cues, such as Splinter's damaged ear, seem to imply similar events to those of the movies.
Many of the elements present in Mirage comics are present: Shredder kills Hamato Yoshi, his pet rat, Splinter, is heart broken and starts living on the streets, witnesses turtles being dropped by a boy when a man tries to help a blind old man crossing the street about to get hit by a T.C.R.I. truck and being exposed to a mutagen flying out of the same truck, gets exposed to the mutagen himself, takes the turles to a shelter, witnesses them mutating, gaining human-body characteristics and becoming smart and decides to teach them ninjutsu which he learned by copying his master's moves while training to protect themselves.However, there is one major difference in the reasons why the Shredder killed Hamato Yoshi. In this version, Tang Shen and Oroku Nagi aren't present. In this version, the Shredder was actually an evil Utrom named Ch'rell, a being who nearly conquered the universe. That's why his punishment was banishment. While being transported by a ship lead by Mortu, Ch'rell escaped and sabotashed the ship, which caused it to crash on Earth. The ship landed in feudal Japan, where Ch'rell heard the legend of the awful demon the Shredder who took over the noble warrior, Oroku Saki. Ch'rell then took the identity for himself after he stole an exo-suit the Utroms made from leftovers from their ship.
In this version, Hamato Yoshi was a Guardian of the Utroms, sworn to keep the Utroms secret idendity and real nature from the rest of the world and protect them from Ch'rell. When he and the Utroms moved to New York City, his friend, Yukio Mashimi, betrayed him. The Shredder and his Foot Ninja (along with his servant, Hun) went to Yoshi's apartment and tried to make him tell them where the Utroms are. However, Yoshi refused and was killed by the Shredder. Splinter tried to save his master and clawed Hun (leaving a scar), but to no avail.
In this version (as seen), the Shredder had direct influense in the origin of the turtles (much like in the 1987 cartoon).
IDW (2011 Comics)
In this incarnation, Oroku Saki and Hamato Yoshi were a part of the Foot Clan. The two were rivals, but two never fought more over anything than over the love of Tang Shen. However, she chose Yoshi and the two married. They had a child named Miwa together. One day, Saki came into their home carrying claw-like weapons attached to his arms (he later gained the title the Shredder) and started a fight with Yoshi. A fire was started, in which Tang Shen perished and Saki became bald. Saki somehow saved Miwa, renamed her Karai and raised her as his adopted daughter.
Yoshi somehow made it to New York City, where he bought himself four baby turtles. On the way to his apartment, he bumped in to man. Sensing something odd about him, he followed him and found himself infront of a meeting between the Kraang. The Kraang attacked, but he defeated them. A canister full of a strange ooze hit Yoshi and turtles, giving the turtles human-like characteristics and turning Yoshi in to and antromorphic rat.
He took the name the turtles gave him, Splinter, and taught ninjutsu for self-protection of the outside world. He gave the names of four Renaissance artist: Leonardo, Michelangelo, Donatello and Raphael.
- The origin of the Turtles borrows elements from the origin of the Marvel Comics superhero Daredevil: an old man crossing the street, an out of control truck carrying radioactive isotopes, a young man pushing the old man out of harm's way. The only difference in plot is the isotope hitting the four baby turtles, instead of the young man near the eyes.
