Leosagi

Leosagi is the slash ship between Leonardo and Miyamoto Usagi from the Teenage Mutant Ninja Turtles and Usagi Yojimbo fandom.

The Big Brawl
As Leo is about to be shot at by a group of assassin's, a Rabbit Samurai appears and disarms the crossbow. The assassin's quickly retreat and the rabbit goes over to Leo's side. He asks if he's alright and Leo thanks him for saving him. He introduces himself, and the rabbit says his name is Miyamoto Usagi. Leo says he's lucky that Usagi was there to save him, and Usagi says that luck had nothing to do with it. He tells him to keep his mind and weapon as one, and Leo asks if he has any other advice. Usagi tells him to duck as a ninja star flies towards Leo. Leo does so while Usagi cuts it down with his katana's.

They fight off the assassin's again, before they disappear. Leo thanks Usagi again, who tells him not to do so just yet. They may end up fighting each other in the tournament. Leo says given the way Usagi fights, he'd rather not go up against him, and Usagi says that the feeling is mutual. They are then interrupted by the Goyji, who gives Leo his swords and tells them that the tournament is starting soon. They head to the tournament and wish each other luck before going their separate ways.

When the contestants are split for the second round, Leo and Usagi are placed against each other. Leo comments that Usagi had said they might and Usagi says that fate often has a sense of humor. Usagi says they should fight as friends and let the best swordsman win. They both then pull out their swords and start to fight one another. As they do so, a poisonous dart is suddenly fired into Leo's shoulder and Usagi looks on horrified as Leo passes out. The Goyji appears and asks what's happened, and Usagi says he doesn't know. He checks Leo's breathing and says it's shallow, the Goyji agreeing that Leo needs a healer. The match is made null and will require investigation, and Usagi insists on taking Leo to the healing area. Donnie then drops into the arena accusing Usagi of being the one to hurt him, but Usagi only wants to help him. Leo wakes up long enough to say it's alright before passing out again, both Usagi and Donnie stopping him from falling. They then escort him to the healer.

As Usagi is about to be skewered by the assassin's, Leo wakes and is able to stop them. Usagi is happy to see that Leo is better, and Leo says he's not, but he can at least breathe. He frees Usagi from his chains and Usagi says that they can finish the assassin's together.

After the Battle Nexus is over, Leo bows to Usagi, who says it was an honor to battle beside Leo and the others. He hopes that they'll see each other again, and Leo says he is the one who is honored. Since Usagi did save his life.

Fanon
Leosagi is one of the more well known and popular ships among TMNT fans. Although it isn't as popular as others, due to Usagi's limited appearances throughout all TMNT series.

Despite Usagi never appearing in ROTTMNT, there is a subsection of fans who create art of him appearing in the series. Much of this art depicts him as a teen and Leo having a crush on him. Due to the cancellation of the series, many fans were disappointed that this would be the one animated series where Usagi doesn't appear.

On AO3, Leosagi is the most written ship for Usagi and the tenth most written for Leonardo. It is also the ninth most written ship in the Teenage Mutant Ninja Turtles (TV 2003) tag and the most written in the Usagi Yojimbo tag.
