|“||My name's Leo. I've got 3 rowdy brothers who always give me a hard time. But I keep them in line... usually. Master Splinter picked me to lead because I eat, sleep and breath Ninjustu. Not that my brothers aren't good, I'm just better. But nothing can get in my way in protecting my family.||„|
Leonardo is the overall main protagonist in the 2012 version of Teenage Mutant Ninja Turtles and a member of the TMNT. He is the younger adoptive brother of Karai, older brother of Raphael, Donatello, and Michelangelo, and the eldest child to Master Splinter. He is "The Leader" of the team. He is voiced by Jason Biggs, then Seth Green.
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.
Leonardo and his brothers were once ordinary turtles: when they were infants, they were adopted from a pet store by Hamato 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.
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.
Leonardo, in the possible/alternate timeline of the mutant apocalypse, became the wasteland warlord Maximus Kong. He is the final villain in the 2012 TV series by production order.
During the detonation of the Mutagen Bomb, Leonardo pushed his brothers to relative safety and took the brunt of the fallout himself. He was mutated into a gigantic, grotesque version of himself, and lost his memory of his time as Leonardo. Eventually, he became the warlord Maximus Kong and traveled the wasteland in a massive truck.
At some point, the Honey Badger Ravagers leader Verminator Rexcame under his command. When Raphael took over the Ravagers and Scale Tail Clan after beating the leaders of the gangs, Verminator Rex ran to Maximus Kong and told him of the Red Stripe Army. Maximus Kong and Verminator Rex then set off to take Mira, the meerkat Mutantwho had the map to the Oasis on her arm, so that they could control the legendary area themselves.
The Red Stripe Army fought Verminator Rex as well as Maximus Kong's Synthezoids. All of the Honey Badger Ravagers and Scale Tail Clan were wiped out, with the Scale Tail Clan's former leader Imperius Reptilicus squashed by Maximus Kong's own truck. Verminator Rex was taken out by Mira, and Raphael took the fight to the warlord himself.
Raphael managed to knock the helmet off of Maximus Kong, and realized that he was in fact his long assumed dead brother. Kong denied this, until he caught a vision of Raphael as he was before the Mutagen Bomb, telling him that he loved him. Slowly, Leonardo began to regain his memories and recounted what happened on the day of the bomb.
Leonardo joined his brothers and the last of the Red Stripe Army and lived at the Oasis in happiness.
Like the intro states, Leonardo is the leader of the Teenage Mutant Ninja Turtles. He 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.
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.
