History (Submitted by TurtleGurl84)

Leonardo: 2002

Leonardo was the first-born turtle of a clutch found on my family's farm. For Leonardo, I used "Rain Storm Blue" to mark his shell.

Leonardo: 2009

Convinced that he and the turtles were reincarnations of a murdered ninja and his four sons, Splinter claimed Leonardo was the oldest of his sons, Hamato Kazuki.

Leonardo: 2009 - 2013

Leonardo became proficient in the use of ninjato and other bladed weapons. He was Splinter's best student and the most captivated by Splinter's stories of their former lives. Leo became a firm disciple of the way of ninjitsu, but he also studied Japanese culture and the samurai. He had Splinter teach him Japanese and esoteric practices of spiritual nature, which his brothers had little interest in.

Leonardo: 2013

Leo did not believe he or his brothers were ready to go into the field when the demonic siege threatened Star City, but he led his team to save many people (and make a memorable impression on several others). But when that was done, the Turtles went back to the shadows for a while.

Leonardo: 2016

When I was threatened, Leo made the call to intervene and protect me, even though doing so made them clear enemies of the Foot Clan.

Supplemental Reports

  • (Submitted by TurtleGurl84) One of the only 'teen-appropriate' activities Leonardo engages in is his love of watching cartoons. Though he loves all animated series, his favorite is Space Heroes, an old cartoon of what looks like a cheap rip-off of another sci-fi series. Leo found the entire collection of VHS tapes in a dumpster. He often refers to his team as "Hero Turtles" and not "Ninja Turtles."


Leonardo is very loyal to master Splinter. He is both the leader and the oldest of the four turtles. Of his brothers, Leo is often the most calm and cool under pressure. However, some outbursts I've seen when provoked or annoyed by his brothers reveal that he has inherited some of that Hamato temper, though one much less volatile than Raphael or Splinter.

Leo takes his training very seriously, and strives to be the best that he can be. Even when he and his brothers are out in the city on patrol or do training sessions, he makes sure that he and his brothers are doing their best and training as hard as possible.

Leo tends to take the weight of the world on his shoulders, expressing self-recrimination for any mistakes he perceives himself or the group as a whole to have made. Leo becomes very frustrated when his brothers are not listening to him.

While he usually tends to play by the rules and listen to Splinter's orders, Leo has been shown to have a rebellious streak when he is prevented from doing what he truly perceives to be as right.

Leonardo is the most spiritually-minded of the four, even characterizing himself as "the one who believes in miracles." Leo even claims to have visions of Tang Shen, the mother of the Hamato children and Hamato Yoshi's wife. Leo was also the turtle most inclined to accept the idea that they were reincarnated, the first one to fully embrace Splinter's belief that cosmic destiny had guided their lives.[1]
