Hamato Yoshi was a student of The Foot Clan and after a setup by his arch enemy, Saki, she was expelled from the school and fled to America's New York City, where he lives penniless in the sewers with rats.  One day, a young boy dropped a bowl carrying four turtles into the sewer, which Yoshi adopted.  Another day, Yoshi comes into a room only to find the turtles covered in glowing mutagen, which he also touches and mutates them all into mutants.  Yoshi mutates into a rat because he was in contact with them.  As a mutant, Yoshi was nicknamed Splinter.  He teaches the turtles the ways of ninjitsu so he can have the turtles take on Shredder (Saki) and save the city above from crime and dangers.  He yearns to be transformed to human form again, but an attempt that could of made him human again failed, Splinter accepts himself as a mutant rat.
