Leonardo likes to play the electric guitar.
Leonardo's katana weapon

Karai - Leo is a little in love with her, but first of all he sees her as a worthy rival. He wanted to get her away from the Shredder, perhaps feeling that she had something to do with them, but not knowing exactly what. Then it turned out that she was Splinter's daughter, which further convinced Leo that Karai was good.
Status: couple

April O'Neill- They're good friends. The information that April gives can be very necessary. Usually he doesn't communicate much with her, but treats her like a sister.

Michelangelo - Leonardo does not like that Michelangelo often bullies and jokes and is not happy about it. But despite this, he loves his brother. Unlike Rafe, he's more relaxed about Mickey's jokes. For Leo, Mickey is like the little brother he loves. The relationship is very good.

Donatello - The relationship with Donatello is trusting, but with disagreements. He usually treats Donny well, trusting him and treating him like a more responsible brother. He often seeks support from Donatello when he sees no other solution. But their differences in personalities and approaches often lead to disagreements. So Donnatello is more gentle and impulsive, more hesitant and also being a younger brother with a huge responsibility, who relies more on technique than on himself, and Leonardo is more mature and experienced, calm and morally strong, who relies more on the spiritual advice of Splinter and himself, which leads to arguments due to misunderstandings and different approaches. He is also often not happy with inventions that he thinks will have consequences. He also quite often hurries Donny, hoping for a full return, which makes Donny very angry. He also puts too much responsibility on Donnatello, sometimes forgetting that he is a younger brother. But in general, he loves him like a younger brother, even though he rarely communicates with him.

Raphael - They almost always quarrel because of the anger problems of Raphael, who does not control anger. Rafe was angry when Splinter appointed Leo as leader, not recognizing Leo's leadership for a long time. Where Leo tries to come up with a plan, Rafe often hits without asking, which causes them to disagree. But Rafe and Leo are two older brothers who are always arguing, but they love each other like brothers. However, despite frequent quarrels and disagreements, they take care of each other. Rafe and Leo are the closest of the brothers, as they often understand each other well when they are not arguing. So Rafe didn't want to let go of Leo, who was sacrificing himself, who was holding Krang Prime back, allowing the brothers and April to escape from persecution. Also, when he was Maximus Kong, Raphael, saying that he loved his brother, forced him to become himself again, remembering who he really was.

Splinter - Leonardo is a strong warrior with a huge heart and will. Splinter appointed him leader because Leo is the calmest and strongest of the brothers, who is able to take responsibility (even though he said at the beginning that he chose him for nothing. Splinter further admitted that he said so in order to harden Leo's spirit). Leonardo himself loves and respects Splinter very much, listening to every advice and lesson carefully.

He also secretly worked with Karai and the Shinigami as a night avenger, destroying the Shredder syndicate in the Foot Clan vs. the Patriots series, where he helped Karai more in revenge against Shredder, temporarily rejecting Splinter's instructions. Also in the episodes of season 4 with Fugitoid, he often showed an evil side: He wanted to leave Chompie on Magdomar, on the moon of Talos 3 he wanted to leave the Salamandrians without showing compassion, he wanted to sharply attack Dregg with Armaggon and Mona after Mona's betrayal. He was also rudely angry at Raphael because of his broken heart from Mona's betrayal. He was also rudely angry at Raphael because of his broken heart from Mona's betrayal. He was also the most angry at the Fugitoid when he found out that he was the creator of the Generator and did not believe him, wanting to destroy the Triceratons himself and almost died. But mostly Leonardo suppresses his dark feelings and tries to be an exemplary brother to the turtles and a good son to sensei.

Leo is the leader of the team and performs his duties, which sometimes bother his brothers, especially Rafa. Leo is the most balanced and calm of all the brothers. He is also the most serious and disciplined of all the turtles and, of course, therefore their leader. He has a lot of responsibility on his hands, which can sometimes overwhelm him. In general, Leo acts as an older brother for the turtles and as the eldest son for Master Splinter. He was chosen as the leader because of his willingness, not because of his skill. Leo is the most mature of all his brothers, always acting like a mentor to his brothers. He is very protective of his brothers, sister (Karai) Miva and April's friend, he's willing to do a lot for each of them. Leo is a big fan of "Space Heroes" and tries to be like the main character Captain Ryan, but Rafe thinks it's a stupid series. Leo often quotes the Captain, which annoys Rafe very much.
Leonardo possesses quite important qualities of a leader: wisdom, determination, oratory, tact, cunning and a huge heart. Leo does his best to lead the team, but sometimes he is tormented by doubts about whether he will be able to become a sensei and be a support for others, because this is a big responsibility. He also has a rather funny side and a sense of humor, but few people seem to appreciate or understand him.
Leonardo also has a dark side, which is more weakly expressed. Partly because of Leonardo's own desire to be better by suppressing her. Leo's shadow side, unlike Rafe's anger problems, is no longer related to anger, but rather to cold calculation and quick achievement of a goal, as he succumbed to his dark feelings and began to believe that any methods are good to defeat the Foot Clan. Leonardo also briefly wanted to secretly kill Shredder behind Splinter and the Turtles' backs in the Revenge episode.

It looks like a green mutant turtle. Compared to the brothers of average height. He wears a blue bandana and uses two katana swords. The eyes are blue. He likes to watch the Space Heroes show, imitating his idol Captain Ryan, but Rafe doesn't like this cartoon, tempting Leo. Karai's first love. Has the gift of a healer. In season 5, after repeated mutation, he looks like a giant human turtle that has been pumped with mutagen, resembling a Super Shredder. All that remained of the carapace was a distorted bone covering on the back, riddled with mutagenic veins. He wears leather belts with spikes, black boots with blue trousers, and a helmet that resembles a bucket that Raphael broke.
