Master Splinter, or simply Splinter is a fictional character in the Teenage Mutant Ninja Turtles universe.
Splinter has two origin stories, and which one is used depends on the medium. In the original version of the tale, he was Hamato Yoshi's pet, and in the other, he is Hamato Yoshi.
In both the original comics and the live-action movies, Splinter was the pet rat of a ninja named Hamato Yoshi in Japan. Intelligent for his species, Splinter was able to learn his master's art by mimicking his movements while he practiced. Yoshi became embroiled in a dispute with a fellow ninja by the name of Oroku Nagi, and was eventually murdered by Nagi's brother Oroku Saki.
Without a home, Splinter was forced to run away and live in New York City's sewers. Due to a traffic accident, four baby turtles and a canister of radioactive ooze were sent down into the sewer, where they mutated both Splinter and the turtles. Splinter named the four turtles Leonardo, Donatello, Raphael, and Michelangelo (after a book on Renaissance artists that he found in a storm drain) and trained them in the arts of ninjutsu, while still raising them as his own sons. Splinter died of old age in Teenage Mutant Ninja...
