Splinter is both the adoptive father and sensei of all four of the Turtles. He's wise, mature, and is highly trained in the art of Ninjitsu.
"For many years I have lived in the shadows, training my adopted sons in the ways of Ninjutsu. I have tried to prepare them for the worst that the world has to offer - hoping it would never come. But we are running out of time. Our family is strong. I only hope that we are strong enough."
AppearanceAs a human, Splinter was tall, lean and muscular, with dark brown eyes and black hair. He wore a red kimoto with his clan's symbol when he lived in Japan. During the time that he resided in America, he wore a whitish blue polo shirt, along with brown pants. Before he was mutated, his true name was Hamato Yoshi.
As a mutant rodent, he has black, brown and white fur, with a droopy white beard, whiskers, a pink tail, and a pink nose. He still wears the red kimoto that he wore in Japan. Unlike all of his part incarnations, Splinter is taller than each of the Turtles.
Splinter is many things to the Turtles – A wise sensei, protective parent, loving father, stern disciplinarian, quirky master and Zen philosopher. He is determined to train and protect his newer family at all costs. The fact that he has gone through decades of ninja training does not only mean that he may be fierce when he fights, but that he is also remarkably in tune with the universe.
Splinter can be very strict when it comes to training and letting his sons venture up to the surface; as seen in MANY episodes. At certain times, he may use harsh methods in order for them to learn a lesson, as seen in "The Pulverizer Returns!", in which he took away his sons' weapons so they could learn to fight outside of their typical environment. Nonetheless, Splinter is a loving father who only wants what is best for his sons, and will do anything he can to protect them from harm's way.
Splinter seems to dislike anyone that lays a hand on the Turtles. This is emphasized in "It Came from the Depths", as he battled Leatherhead due to this. His absolute worst fear is losing his family all over again to the Shredder, as seen in "Panic in the Sewers." His fear of losing the Turtles to Shredder caused him to push their training to the point where they become exhausted, stressed, and antsy; though he does eventually apologize for it. It could be very possible that Splinter fears the fact that the Turtles will leave him someday, as this was one of the notions that the Rat King (in "I, Monster") used against him in an attempt to control his mind.
Abilities and Powers
As a master of Ninjitsu, Splinter is knowledgeable, speedy, and surprisingly strong. He can take down larger opponents without a whole lot of effort, as demonstrated in "It Came from the Depths." He can also easily detect when an enemy is coming; This is either due to the excellent hearing that he got when he mutated or his "balanced mind".
Similarly to April, he appears to possess a rare sensitivity gift.
Splinter is skilled with the usage of many weapons as well.
It is revealed in "Booyaka-Showdown, Part 2" that, thanks to his rat form, he has alot of abilities that ordinary rats possess - namely running on all fours and a bite force that is powerful enough to break some forms of metal.
Master Splinter was once a human master of Ninjutsu named Hamato Yoshi. His skills were only rivaled by the Shredder, then known as Oroku Saki, who he was once friends with. Not only were they rivals in Martial Arts, but also for the love of a beautiful woman named Tang Shen. She finally chose to marry Yoshi. Saki could not accept this and once brutally insulted Yoshi in front of his own bride. Yoshi lost his temper and struck Saki to the ground. This attack solidified Saki's hatred for Yoshi and he vowed revenge. One night, he came to Yoshi's home and challenged him to duel to the death armed with razor sharp claw weapons. During the fight, a fire broke out and Yoshi's home was burned to the ground. His wife perished somewhere in the flames. He never knew the fate of his baby daughter Miwa.
Yoshi made his way to America and attempted to make a new life in New York City. One day, out of loneliness, he visited a pet store and purchased four baby turtles. Walking home, he bumped into a man. Yoshi felt off about him and decided to follow. He came into an alley and overheard a conversation between two strange men, later shown to be members of the Kraang. His foot spooked a rat hiding in the alley, causing the villains to spot him and attempt to kill him. Yoshi fought back, but accidentally broke a canister of Mutagen they were holding in the process, spilling it all over himself and the turtles. Yoshi escaped down a sewer drain, now mutated into a humanoid rat. The turtles also mutated, gaining humanoid bodies and intelligence. Yoshi, knowing that they would be persecuted by humans, adopted these turtles as his sons and students and has raised them in the sewers of New York ever since. He started training them in his Ninjutsu techniques because he knew that, one day, his sons would want to explore the surface, but he knew it would also be dangerous. He took on the name of Splinter and gave the turtles names of painters and sculptors from a book of Renaissance Art he found in a storm drain.
