Intelligent for his species, Splinter is able to learn ninjutsu art by mimicking his master's movements while he practiced . Yoshi becomes embroiled in a dispute with a fellow ninja by the name of Oroku Nagi, and is eventually murdered by Nagi's brother, Oroku Saki, who is seeking revenge for his brother's death . However, in the 1990 film and 2003 TV series Nagi is removed entirely . Additionally in the 1990 film, Splinter escapes from his cage during the murder, and attacks Saki, clawing at his face . Saki in turn slices his ear off . It is suggested that this mutilation is the reason Saki took the Shredder disguise to hide the scars .

Due to a traffic accident, four baby turtles and a canister of radioactive ooze are sent down into the sewer . The canister mutates both Splinter and the turtles . Splinter names the four turtles Leonardo, Donatello, Raphael, and Michelangelo (after a book on Renaissance artists that he found in a storm drain) and trains them in the arts of ninjutsu, so that they can take revenge for his dead master, while raising them as his own sons . </P>
