Leonardo (1987 TV series)

Biography
Leonardo was a pet turtle along with three others who had been bought by a boy, but the boy tripped and the four turtles fell into a sewer drain. At the time, Hamato Yoshi had been hiding in the sewer from his enemy, Oroku Saki, and had become a friend of the rats living down there. Hamato was overjoyed to find four new friends, and welcomed the turtles into his home. At some point after, Hamato noticed the turtles covered in a glowing substance, and he touched the substance himself. The turtles had most recently touched Yoshi, causing them to quickly evolve into human-like turtles. Hamato, having just been exposed to the rats, became a human rat. Hamato saw the turtles’ potential to challenge the one responsible for the mutations to change him back to a human, and trained them in the art of ninjitsu, and naming them after some of his favorite Renaissance artists – Michelangelo, Leonardo, Rahpael, and Donatello.

Some years after, April O’Neil was giving a news report on a recent break-in at a science lab, and a scientist used witnesses of the thieves and bits of rope to conclude the thieves were most likely ninja. April and her crew went to the next potential science lab robbery, only to moments later be chased by a group of street gang members. April managed to slip into a sewer drain, but the gang members followed. Suddenly, a second group of ninjas appeared and took out the gang. April fainted when she saw Leonardo and the other ninja were turtles. Leonardo and the others took her to their Master Splinter, (Hamato Yoshi’s nickname given by the turtles) who explained the turtles’ origin to her. April, however, believed that the turtles were the thieving ninja, but the turtles made a deal: they would help her find the one behind the thefts and get her a story, while she would try her best to find the mutagen creator. She took the turtles to the surface ad bought the turtles coats and fedoras to keep the turtles body unrevealed, and went to the scene of the crime, finding only a matchbox with the words “Ninja Pizza” on it. They found and went into a restaurant by the name of Ninja Pizza and ate there. April left and scouted the neighborhood to find a security building, and heard orders being given out to rob a science lab. April was going to phone Channel 6 (the news station she worked for) and tell them she had found the ninja, only to be captured. Shortly after this, Leonardo and the others expressed their concerns for April’s long disappearance and found her belongings, finally finding her tied to a chair on top of a building. A group of ninja assaulted the turtles, who found out their attackers are just robots. Oroku Saki, watching the fight from a closed camera system, demanded his remaining Foot robots to set off the sprinkler system in the building. Leonardo, April, and the others managed to escape before the building exploded from the pressure.
