Teenage Mutant Ninja Turtles (1987 TV series)

Teenage Mutant Ninja Turtles (1987 TV series) is an American cartoon series created by Murakami-Wolf-Swenson (animation studios).

Synopsis
The origins story in the 1987 television series deviates significantly from the original Mirage Studios comics. In this version, Splinter was formerly human, an honorable ninja master named Hamato Yoshi who studied art history as a hobby. He was banished from the Foot Clan (a Japanese dynasty of ninjas founded by one of his distant ancestors[8]) after one of his students, the power-hungry and seditious Oroku Saki (who resented Yoshi's leadership within the clan and aspired to usurp him), set him up for an offense against a visiting master sensei. One day, Saki pinned Yoshi's dogi to the wall with a knife, preventing him from kneeling before the sensei, which was seen as an insult. When Yoshi removed the knife, the sensei was again insulted, believing that Yoshi was drawing the blade in an attempt to kill him. Disgraced, Yoshi left his native Japan and relocated to New York City without a penny to his name. Now homeless, he was forced to live in the sewers with the rats as his only friends. Meanwhile, Saki is given command of the Foot Clan, which he corrupts and transforms into a criminal organization.
