Leonardo

Leonardo: 2002
Leonardo was the first-born turtle of a clutch found of my family's fam. 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 has Splinter teach him Japanese and esoteric practices of spiritual nature, which his brothers had little interest.

Leonardo: 2013
Leo did not believed he and 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 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 is his love of watching cartoons. Though he loves all animated series, his favourite 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".

Trivia

 * Leonardo is the most dedicated of Splinter's students and is debatably the most skilled. He seeks to carry out Splinter's teachings above-all, and often carries this burden with no small amount of stress, causing him to often butt heads with his brothers, particularly Raphael.
