Leonardo, aka Leo, is a member of the Ninja Turtles. He is a Red Eared Slider Turtle who is the leader of the Ninja Turtles and the oldest of his brothers. As the leader of his team, he is the best pupil of Splinter, is very skilled in Ninjitsu compared to his brothers, and also takes Splinter's advises more into consideration. Later on after the death of his master, he becomes the new leader of the Hamato Clan and therefore becomes the new sensei of Raphael, Donatello, Michelangelo, April O'Neil, Casey Jones, Karai and Shinigami. Wearing a blue bandanna that represents leadership, he wields a pair of Katana Swords as his signature weapon of choice. He is in love with Karai. He has a rivalry with Raphael(brotherly), Takeshi/Tiger Claw, Oroku Saki/Shredder/Super Shredder, Kraang/Kraang Prime and Count Vlad Dracula. Leonardo debuts in Devastation.

## History

Fifteen years ago, Hamato Yoshi had suffered the loss of both his wife, Tang Shen, and his daughter, Hamato Miwa, by the hands of Oroku Saki after a fire that took place in the Hamato Dojo in Tokyo, Japan one night. Since Yoshi had lost everything on that night, he fled to New York City to start a new life, which was the place that Tang Shen wanted to move to with Yoshi and Miwa. One day in New York, Hamato Yoshi went to a pet store and brought four baby turtles. As he was leaving from the pet shop to head back home, he bumps past a strange man in the streets. Yoshi had bad vibes about this man and decided to follow him, leading him into an alley.

That was where he saw the man meeting up with a group of men that were identical in appearance to him. As they gathered around, one of the men was seen holding what seemed to be a canister with a weird, green substance. But then the meeting was interrupted when Yoshi accidentally steps on a rat that was passing by him, causing him to blow his cover. The group of men spotted him and so a fight occurs when Hamato Yoshi tries to defend himself from the men. During the fight, the canister falls on both Yoshi and the four baby turtles, causing the substance to spill and mutates all five of them.

With the ooze coming in contact with them, Hamato Yoshi mutates into a humanoid brown rat, which was the last animal he came in contact with before his mutation. In the other hand, the four red eared slider turtles mutate into humanoid versions of themselves. Due to their new mutant forms, they fled from the surface and moved into the Sewers so that they could live there. The five mutants move in an abandoned subway station, which they now call home. Hamato Yoshi, now adopting the nickname "Splinter" becomes the adoptive father of the mutant turtles and names them after his four Renaissance Italian artists. One of the turtles was named Leonardo, named after the Renaissance Italian artist, Leonardo Da Vinci. At some point while Splinter started to raise the turtles, he introduces them into the ways of Ninjitsu in order to become the new ninjas of his family's clan, The Hamato Clan. During their training, Leonardo was given a blue bandanna and a pair of Katana Swords as his signature weapons of choice.
