Leonardo

Leonardo or Leo is one of the four main protagontists in Teenage Mutant Ninja Turtles and a member of the TMNT. He is the younger adoptive brother of Karai, older brother of Raphael, Michelangelo, and Donatello, and the eldest Male child to Master Splinter. He is "The Leader" of the Team.

Description
The leader of the Turtles, Leonardo aspires to be a brave, decisive, perfect hero. Unfortunately, he's an inexperienced teen (for the moment at least) with three smart-aleck brothers. It's the gap between his aspiration and current situation that is the greatest source of frustration in Leo's life. He's the most driven of the four Turtles, training and studying relentlessly. He tends to be hard on himself, but his diligence does not go unnoticed; he is the favored student of Splinter, whose approval he very much craves.

History
Leonardo and his brothers were once ordinary turtles: when they were infants, they were adopted from a pet store byHamato Yoshi. When their soon to be father walked passed a strange man, a Kraangdroid, he felt something odd about him and followed. Unfortunately, Yoshi gave away his position when he accidentally stepped on a brown rat's tail.The Kraang found him and attempted to kill him, but Yoshi fought back hard. In the end, the Kraang dropped the canister of Mutagen they were holding, causing the turtles and Yoshi to mutate. Yoshi, having to have stepped on that rat, thus mutated into a humanoid brown rat by the name of "Splinter", while Leo and his brothers, after coming in contact with Splinter when he was human, mutated into humanoid turtles. Splinter knew they would never be accepted in their urban society, so he took them to the sewers, made a home down there, and made the four turtles his children. Knowing the world would be dangerous and there would be a time where they want to explore the outside world, Splinter trained the boys in the art of Ninjitsu. Leo and his brothers were named after great Renaissance artists from a book Splinter fished out of the storm drain.

Appearance
Leo is an emerald green colored mutant turtle with sapphire blue eyes. He wears a blue mask where the tails length range between Donnie and Mikey's. Like Raph, Leo doesn't have much changes to his physical appearance like all his previous incarnations, except for the fact that his green skin is slightly darker than the others. His height ranges between Raph and Donnie's. He is lean, looks more mysterious and is handsome and or charming.

Personality
Like the intro states he is the leader and makes the commands which sometimes bothers his brothers especially Raph. Leo is the most serious and disciplined out of all the turtles and is of course their leader. He has a lot of responsibility on his hands, which can sometimes overwhelm him. He watches a T.V. Show called "Space Heroes" and wants to be just like the captain he sees on T.V. Overall, Leo acts as a big brother to the turtles and as a teacher's pet to Master Splinter. He was chosen to be the leader because of his willingness not by his skill. Leo is the most mature out of all his brothers, aside from Donnie, always acting like a guide and sometimes even a parent to his brothers. He is very protective of his siblings and is willing to do anything for them. Unlike all his incarnations, Leo is somewhat a sci-fi geek, aside from Donnie. Though Donnie is more of a techy geek. Leo loves "Space Heroes" and tends to try to be like the hero on there, much to the annoyance of his brothers. He also tries too hard to act like a hero and says cheesy lines, which annoy Mikey, Donnie and Raph. He is the wisest, most experienced and balanced of the team and demonstrates many important qualities needed in a leader. Leo does his best to lead the team, but he sometimes second-guesses himself and his constant sibling rivalry with Raphael can cause problems for the team and puts a strain on his relationship with Raph. He often tries to compare himself to the main character of "Space Heroes", Captain Ryan, which annoys his brothers. Like other incarnations, Leo is a perfectionist. He developed a crush on Miwa/Karai/.

Bio
Hardworking, honorable and respectful, Leonardo is the Turtle's fearless leader. Driven to be the perfect hero, Leo's inexperience and often rowdy brothers sometimes get in the way of his goal.
