Leonardo is one of the four main protagonists of the Teenage Mutant Ninja Turtles franchise. He is the leader of the turtles, and also the oldest member of Donnatello, Raphael, and Michelangelo and also the arch-nemesis of Shredder.
Leonardo appears to be a normal, healthy teenage mutant turtle. He is muscular and stocky like his brothers. His skin tone is forest green and he wears a blue ninja bandana. As of the season three finale, part of his shell by his left shoulder was broken off during the final fight with the Shredder, after Karai stabbed him in the shoulder.
Leonardo is the leader, whose key attributes consist of honor, sensitivity, patience, and encouragement. He is the most "spiritual" of the four brothers. Despite being a teenager, he acts kind of like a grown-up due to all his seriousness, but can still have fun with his brothers.
Of the brothers, he has the closest bond with Splinter, often going to him for help and attempting to follow his orders to a T (at least when his brothers aren't out causing trouble, forcing him to go along with their antics). While responsible, Leo can still be sucked into trouble by his brothers out of his own curiosity or his sense of duty to keep an eye on them.
Leo has a strong sense of honor and ethics, along with being a dedicated follower of the Bushidō code. Episodes that deal with the Shredder and honor usually also focus on Leonardo. He is also often the Turtle who "saves the day" (in fact, Leonardo is the turtle who decapitates the Shredder early on in the series—of course, before they are aware that Shredder is in fact an evil Utrom by the name of Ch'rell who doesn't have a neck, let alone a distinct head).
Raphael and Leonardo occasionally argue, with Leo annoyed at Raph's hotheaded tendencies and Raph annoyed at Leo always getting on his case. They have had this dynamic since they were kids, with Raph even admitting that he thought he would be the leader one day, only to have Leo take the position instead. However, the two are still shown to be very close and joke around with each other in more playful times. All three of Leo's brothers view him as a pillar of strength. They are at a loss when he is injured or absent, such as in the first season when the Foot Clan beat him unconscious and put him near death.
One of Leonardo's most prominent qualities is his determination to believe the best in people, even potential enemies (i.e., Quarry, Traximus and Karai). This trait can cross over with being naive, though, as his trust almost led him to siding with the Shredder the first time they met. Even so, he is willing to give even people who betray him a second chance if he sees good in them, such as with Karai. His trust in her was shaken multiple times due to her inability to pick a side, but he still risked his life to save or assist her. He only considered her a real enemy once she tried to kill his family, but even that passed once she showed her honor again.
Leo may be the most mature but don’t be fooled. When Leonardo loses his temper, he would have emotional outbursts just like Raphael would if he was upset. Sometimes his explosive outbursts can be more violent and raging than Raphael’s. The first half of the fourth season shows a more traumatized, dark Leonardo, due to his feelings of failure, as did a short period in season one after the Shredder returns, in which he became depressed and angry. It wasn’t until he accidentally injured Splinter and subsequently received training from the Ancient One that his personality returned to his normal calm, happy, and reassuring self.
Leonardo was a pet turtle bought by a young boy along with three others, Donatello, Raphael and Michelangelo. The boy was waiting at the crosswalk when a teenager noticed a blind old man crossing the street while a truck sped toward him. The teenager bumped into the boy with the turtles, causing him to drop the jar in which he held them. The turtles fell into the sewer. Meanwhile, the teenager had successfully saved the old man's life. While the truck veered away from the scene, the doors flew open and a canister fell right into the sewer with the turtles, covering them with an odd substance. A rat by the name of Splinter was passing by and picked up the turtles, touched the odd chemical as well, when one of the turtles shook it all over him. When Splinter woke up the next morning some point later, he found he and the turtles had grown taller, and slightly more intelligent.
Splinter thought it wise to train them in ninjutsu, just as his Master Yoshi had unknowingly done for him. Leonardo and his brothers were taken by Splinter to Japan when they were children to bury Hamato Yoshi's ashes with Tang Shen's remains, and alerted the Ancient One of his and Yoshi's condition. The turtles constantly noticed an odd demon visible to them, but invisible to the Ancient One and Splinter. Finally, when the Ancient One went to consult with the Ninja Tribunal, Splinter noticed an odd smell in the air, believing it to belong to the demon the turtles continued to see, and they secretly followed the Ancient One. The two ninja masters finally were attacked by the demon, but Don managed to throw a stone at the amulet, causing it to shatter and reveal the demon. The Ancient One and Splinter quickly killed the demon. The Ninja Tribunal applauded the turtles' efforts, though eradicated all memories of the trip. The Ancient One gave the turtles bandanas, Leonardo's being blue. The Tribunal used their connection with nature to wrinkle space and open a portal to the turtles' current lair.
Later, Leonardo found Donatello pursuing a remote-control car that had gotten caught in the flow of the sewer water. Donatello's life was endangered by large amounts of sewer garbage, but Leo managed to free his brother.
At some point, Splinter had discovered Leo was afraid of heights and trained him for weeks to conquer it. When it proved fruitless, Splinter faked a fall, which succeeded in forcing Leo to conquer his fear by focusing on saving his father.
Even as a child, it was shown that Leonardo was extremely focused on his training, able to ignore Michelangelo's antics until the latter tried to fight him which resulted in the latter's foil.
Seasons 1-4 (2003)
Leonardo was introduced in the first season where he and his brothers are fighting Purple Dragons for the first time. In The Shredder Strikes, Part 1 Leonardo is almost tricked by the Shredder when the latter offers him to join the Foot Clan. After consulting Master Splinter, he then rejects the offer. In The Shredder Strikes, Part 2, The Shredder battles them, and plots to destroy Leonardo but is defeated. In The Shredder Strikes Back, Part 1, and The Shredder Strikes Back, Part 2, Leonardo goes out for a morning run where he is ambushed and defeated by the Foot Ninja, Hun, and the Elite Foot Ninja and finally the Shredder. He lands in April's apartment where the others help to evacuate him out. After the Shredder burns down April's apartment the gang retreats to a farmhouse. During this time Leonardo is in a coma but his driving spirit frees him. In The Monster Hunter, while Donatello, Michelangelo, and Casey Jones are helping a creature escape a scientist, Raphael helps Leonardo, by helping to forge him new katana swords. The gang eventually returns to New York in the Return to New York trilogy and at the end Leonardo uses the Sword of Tengu to defeat the Shredder. After that Master Splinter goes missing, and the Turtles infiltrate the T.C.R.I Building to find him but are found out by the Utrom and are teleported into outer space.
After arriving in space Leo and his brothers help Professor Honeycutt in a series of mayhem against the Federation and Triceratons. The are blasted back to earth were the battle the Shredder and his army in the T.C.R.I building. Leonardo becomes angry that with the Shredder's defeat, the Foot, Mob, and Purple Dragons have engaged in a war for control of New York. Raphael tells Leo not to get involved in the war but Leo ignores him. Leo also meets Karai in this arc. Leo also battles the Ultimate Ninja, and wins. In the Season 2 finale arc the Turtles get sent to the Battle Nexus tournament. Leo befriends Usagi, a samurai rabbit who is also honorable and shares Leo's interest in swords and Bushido.
In Season 3 multiple things happen: the Triceratons invade Earth, the Fugitoid returns, the Turtles meet Agent Bishop, and meet Renet in which they travel through time with the Time Scepter. Ultimate Drako returns and plots to scatter the turtles across time and space. Leo gets sent to the world of his best friend Usagi. In the Season 3 finale, Exodus, Part 1, and Exodus, Part 2, the turtles confront Shredder for the final time. The Shredder is planning on leaving Earth to control galaxies, but is stopped by the Utroms and is sent to permanent exile. This event causes a dramatic change in Leonardo.
For the first half of the fourth season, Leonardo develops Post Traumatic Stress Disorder (PTSD) when he becomes mentally damaged because of the turtles final fight with the Shredder. He believes he wasn't good enough a leader to save his family without the Utroms rescuing them. This goes on until he injures Master Splinter out of rage. He is then sent to train with The Ancient One in Japan. He returns in Prodigal Son where Karai supposedly "killed" his family in Scion of the Shredder. Leonardo eventually rallies his family and finds a new lair. In the episode Outbreak, Donatello gets infected by a Monster, and mutates into one in Adventures in Turtle Sitting. In the Good Genes duo log Leo, Raph, Mikey, Leatherhead, and Splinter travel to Agent Bishop's base to demand a cure for their brother. After that the Turtles now go out on the rooftops again but are kidnapped by wooden ninja, the explanation of which expands in the next season.
In the fifth season, as he is a part of the eight acolytes under the Ninja Tribunal's training, Leonardo is the only one who doesn't receive a weapon from the Spirit Forge. The reason is unknown, but it's possible that while it saw him and Faraji as both worthy candidates, it sensed a greater force in Leo meaning he didn't need a weapon.
His otherworldly form is that of a dragon, a rare form, unheard of in someone his age. It could be a reason why the Spirit Forge didn't give him a weapon, and Kon, of the Tribunal, mentioned that he and the rest of the Tribunal were right about Leo, meaning they could have known he was given a great power that meant he didn't need a weapon. It is shown destroying evil guarding the second artifact with its ki alone. This avatar is first shown in More Worlds Than One. His brothers later exhibit dragon avatars as well. In the fifth episode Beginning of the End, he is given the sword Gunshin by the dying Faraji Ngala. He returns Gunshin in episode 12 Enter the Dragons, Part 1 when Faraji returns to help battle the Tengu Shredder.
In the Fast Forward season, and the Back to the Sewer season, the damage that occurred to Leonardo's shell as stated above has somehow been repaired. Leo, Splinter, and his brothers are sent to the future by Cody Jones and Leo often calls Cody "little ninja". Leo still remains the most skilled. However, he does not play as big of a part in this season as in the previous five. He is still the level-headed eldest brother.
In one episode focusing on Leo, Darius Dun, Cody's uncle, made dangerous clones of the Turtles designed to kill them. In a fight, Leo's clone is hit with a laser by Donatello's clone. He is knocked unconscious and the Turtles take him in (under security precautions, of course). Leo gives his clone a chance to redeem himself and join Leo and his brothers, but the clone betrays their trust and runs away. However, it is later shown that Leo's words have had an effect on the clone, who now wants the other clones to stop living like animals and share, as Leo, Raph, Donnie, and Mikey have taught him.
Back to the Sewer
In the Back to the Sewer season, Leo and his brothers must find Master Splinter's data bits after Viral blasted him apart into Cyberspace. At the end of the series, Leo helped get Splinter back and goes to Casey and April's wedding. After that, Leo and his brothers battle the Cyber Foot and defeat the Cyber Shredder. Leo also sees Casey and April get married after all the Foot Ninja and the Cyber Shredder are defeated. Leo is still the most skilled in combat despite the fact that he did not kill the Cyber Shredder.
As in the previous season, he does not play the lead part in this season. He mostly serves as a support character for Donatello's role.
Skills, Powers, and Abilities
Leonardo is extremely skilled and is very effective with his swords. He displays balance in physical strength and mental strength. He is the most responsible as he has to obey Master Splinter and keep an eye on his brothers.
Leonardo primarily fights with his twin katana swords, but has used shurikens, grappling hooks, claws, and those of his brothers.
Leonardo and Donatello have been shown to get along well. Leo knows the value of Donnie's intelligence and like all of his brothers, he often relies on his engineering skills to get them through any situation. Leonardo and Donatello rarely argued in this series.
Raphael and Leonardo can be competitive and butt heads at times, but other times the two have shown to care about each other, and will help each other.
Like Donatello and especially Raphael, Leonardo gets really annoyed with Michelangelo’s pranks and wisecracks, and scolds him for his lack of focus but does show love towards his little sibling.
Leonardo is the closest turtle to Master Splinter and is loyal to him. He knows what master Splinter expects of him and will do anything to meet his expectations.
Why He's A Blue Pizza Loving Turtle
- He is a very mature turtle and proves himself to be a great leader and second only to Raphael, he’s probably the more serious and confident one of the Turtles.
- If anything, he is the most mature and responsible of the four brothers, and takes honor and responsibility as he is suppose to do.
- He is always an honorable leader throughout the shows 7 season run.
- He always takes responsibility for whatever problem occurs and will take the blame for what others do.
- His voice is very awesome, considering his voice actor also voiced Dean Venture (Michael Sinterniklaas). Season 4 was his best season he voiced Leo as he puts so much effort and especially when he was suffering depression, Sinterniklaas does a good job especially making an intimidating voice.
- He is well animated and looks awesome, it shows the effort that the creators put and is completely familiar of his Mirage Comic Design looks like the Mirage Turtles from the Comics.
- Whenever he battles the Shredder or the Foot Clan, his skills are always enjoyable as he has awesome skills using katanas showing how he trained for a long time.
- He’s also usually the “voice-of-reason” of the group as although Donatello is smarter, Leo is more of a reasonable person and will question his brothers decisions. He manages to be smarter in some ways such as Martial Arts due to the fact that he loves to learn more and more about it.
- He spawned an Internet Meme as the dead turtle inside. There is the meme where He looks dead inside.
- He saw a lot of character development as the series progressed, especially around Season 3-4 where we see is rougher and crueler side. He manages to get stronger as the series progressed, his wise self notably improved and so did his chemistry with his brothers.
- He is a very sympathetic character and truly cares a lot for his brothers, and father. As well as April and Casey.
- He's very sympathetic and tragic when his badly beaten and nearly killed by Shredder and his foot soldiers after showing loads of persistent in, "The Shredder Strikes Back" parts 1 and 2.
- The first half of Season 4 showed his rougher side in a fantastic way as we see how damaged and traumatized he is, following his fight with the Utrom Shredder and nearly being killed. His redemption is fantastic as he really goes to show how much he wants to change himself and return to how he was originally shown.
- Leo's Depression Arc is well-done since it shows the severe impact that he has faced following his battle with Ch'rell.
- His battles with the Shredder, especially in season 1, are always entertaining considering that he is a trained ninja in the art of Ninjitsu.
- Leonardo has shown himself to be a very wise character with a lot of good tales, particularly, his tale on Hamato Yoshi.
- Although the other turtles feel as if Karai really does show no mercy for the turtles, Leo does show as if there is something good out of Karai and how she is better than her "father" (the Utrom Shredder) and how she can redeem herself from being evil.
- He has shown to have a great, strong and healthy relationship with his brothers, specifically Raphael and Master Splinter. Likewise, he has a wonderful relationship with Donatello and even Michelangelo, despite the fact that he may irritate him.
- He puts anyone loyal to him first, he always decides to think more about others rather than thinking for himself. This is presented in Enter the Dragons as he was at his best.
- Even when the show went downhill in quality, he was never flanderized and kept all of his charms as a leader and remained one of the most likable characters on the show and he is still a fan favorite of the franchise.
- He is arguably the most faithful version of Leonardo since this Leonardo is just as realistic as his mirage version self (with a few exceptions).
- Rather than the usual, Leonardo becomes the leader, We can see how he became the leader and is given excellent character development.
- Has amazing and well detailed animated design.
- His voice actor, Ben Schwartz, does a awesome performance, making him sound like power.
- His weapon and skills tend to get better as the show progressed. At start, he does a bad job, but improves for the better.
- His one liner's (while cringey at times) are absolutely hilarious to listen to.
- Whenever he does something wrong, he always owns up and decides to fix his mistake.
- As shown in the season 2 finale, he deeply cares about his friends and family, and hates seeing them in danger.
- He finally becomes the leader at the end of season 2. Despite being rushed (due to Executive Meddling), he is given the reward he deserves.
- He became a jerk in season 4, though he did suffer from PTSD (Post Traumatic Sleep Disorder, and he did redeem himself).
- Sometimes, he can show that he does not want to accept the loss and brings himself down if he ever disappoints anyone.
- "The Shredder Strikes Back (Part 1)" showed how naive he can get as a character and how he was quick to jump to conclusions when he thought Oroku Saki could be a good guy, even though he was nearly being manipulated. Thankfully, Splinter showed him how Saki was actually evil and wanted world domination, helping Leo and his brothers to victory in their first battle.
- In Seasons 1-4, he tends to get the most focus out of the four turtles since most episodes tend to revolve around him way too much, especially in season 1.
- He can be unlikable in some episodes such as "Dragon's Rising" where he chews out his brothers in a cruel way and blames them for everything. He's also unlikable in "City at War - Part 1" where he decides to take part in the war that is happening in the city and worsens the whole situation.
- He starting out as not the leader, did throw off fans.

- In the season 3 finale episode, he was stabbed in the shoulder. In early season 4, when his bandages were removed, it was revealed that a portion of his shell had been hacked off too. But in Fast Forward and Back to the Sewer the injury was removed.
