—Theme Song

Hamato Yoshi, aka Splinter or Master Splinter, is an ally of the Ninja Turtles. He was formerly a Japanese male known as Hamato Yoshi, who was the son of Hamato Yuuta, leader of The Hamato Clan, and was the husband of Tang Shen and father of Hamato Miwa. After getting his family destroyed by his stepbrother Oroku Saki, he fled to New York City to later on buy four baby turtles and gets mutated with the Mutagen into a mutant brown rat, who later on raises the four mutant turtles as his own children. He then trained Leonardo, Raphael, Donatello, and Michelangelo (and years later the sensei of April O'Neil) through the ways of Ninjutsu, which became useful once they emerged from the Sewers and started to fight against The Shredder and The Foot Clan. Years later he learns that his daughter was Karai and then he was able to get her back into his side to fight against The Foot, until The Shredder mutated himself and assassinated him, which lead to Leonardo becoming the new sensei and leader of The Hamato Clan. He wields a cane with a sword as his signature weapon of choice. He has a rivalry with Oroku Saki/ The Shredder/ Super Shredder/ Undead Shredder and The Rat King. Splinter debuts in Rise of the Turtles Part One and Hamato Yoshi debuts in Tale Of The Yokai.


As Hamato Yoshi

2D Young Yoshi And Saki
Hamato Yoshi was born in 1962 in Tokyo, Japan, and was raised by his unknown mother and his father, Hamato Yuuta, who was the leader of a clan that belonged to their family known as The Hamato Clan. Yoshi was going to lead his family's clan after his father, but he went through training years before. The ninja clan had an ancient rivalry with The Foot Clan, another ninja clan lead by Oroku Keiji, which was later on defeated by The Hamato Clan. Yuuta adopted the orphan child of Keiji, Oroku Saki, who was raised alongside with Yoshi and were both trained into the ways of Ninjutsu by their father. The two brothers had a rivalry while training, and the rivalry grew when the two of them fell in love with the same lady, Tang Shen. The two competed to get her, but at the end, Tang Shen chose Hamato Yoshi over Oroku Saki.
2D Shen And Yoshi With Baby Miwa
This enraged Saki and became jealous of his brother's relationship, claiming that "he took Tang Shen away from him". At a unknown time period, Hamato Yoshi and Tang Shen were married and then they became parents when they had their first child, naming her Hamato Miwa. Later on when his father was dying and he was becoming distracted by taking care of both his family clan and his family, Oroku Saki learned the truth of his background and claimed the throne to The Foot Clan, he went after Yoshi to seek vengeance for taking Shen away from him.
2D Saki Versus Yoshi
That night when Saki and Yoshi fought each other, the Hamato Dojo started to burn down in a fire which occurred when Saki struck candles with his Tekkō-kagi. In the climax of the fight, Saki was about the end the life of his stepbrother with his Tekkō-kagi, until Shen interfered in the fight took the blow herself, which caused the tragic death of Hamato Yoshi's wife.
2D Yoshi Defeat
Devastated by the death of the girl that they both loved, Yoshi and Saki were heartbroken and the face of Oroku Saki was burnt by a burning piece of ceiling that fell on his face. Saki and Yoshi both escaped from the Dojo that was burning down and on that very night, Oroku Saki had taken away Hamato Yoshi's family, which was an event that had scarred Yoshi for life.

As Splinter

After Hamato Yoshi lost his family in a tragic fire in the Hamato Dojo, and his father Hamato Yuuta died, he fled to New York City (which was somewhere Tang Shen wanted to visit) to start a new life and try to move on from everything that happened to him on that tragic night. One day (once he was in New York) he purchased four baby red-eared slider turtles from a pet shop. When he was on his way to his house, he bumped into a strange man in the street, which he sensed something sinister about, causing Yoshi to follow the man into an alley.
Hamato Yoshi Fights Normans
Hamato Yoshi was spying on the man who was trading a canister with a green substance with other identical men, but after he accidentally steps on a rat that passed by him, he was spotted by the men and they intended to annihilate him.
Baby Turtles Mutation
After he defended himself from the men and fought them off, he caused the green substance to fall on him and the four baby red-eared slider turtles, which caused them to all mutate into four humanoid red-eared slider turtles and Hamato Yoshi into a mutant brown rat. After realizing that the outside world would not be comfortable with their mutant forms, they decided to hide in the Sewers to make themselves home in an abandoned subway station. Renaming himself as Splinter, he then expanded The Hamato Clan by training the Ninja Turtles into the ways of Ninjutsu and raised them as his sons. He also named them after his four favorite Italian Renaissance, naming them Leonardo (after Leonardo da Vinci), Raphael (after Raffaello Sanzio da Urbin), Donatello (after Donato di Niccolò di Betto Bardi), and Michelangelo (after Michelangelo di Lodovico Buonarroti Simon). After a while of training, the Turtles were given their signature bandannas and signature weapons. Leonardo receives his blue bandanna and pair of Katana Swords, Raphael receives his red bandanna and pair of twin Sais, Donatello receives his purple bandanna and 6-foot-long Bo-Staff/ Naginata, and Michelangelo receives his orange bandanna and pair of twin Nun-Chucks/ Kusarigama.

  • Unlike most of his incarnations, Master Splinter is taller than the Ninja Turtles.
  • Splinter's name is a spoof on the Marvel Comics character Daredevil. Matt Murdock, after being blinded by spilled radioactive waste, is trained in martial arts by a master call The Stick. "Splinter" is a spoof from this name.
  • His main pillars of Ninjutsu are spirit and wisdom.
  • Though the Ninja Turtles are getting older and mature, Splinter is still the strict and doting father as always and can humiliate the boys whenever he feels like it.
