Summary
alternatively titled “so be it.” Set in my own tmnt iteration, but can be interpreted as 03 if you ignore certain parts of canon.
Leonardo has always been the golden child. Perfectly perfect, like all things should be.
So when he can’t take it anymore, he runs away to everyone’s favorite interdimensional death trap: The Battle Nexus.
Fortunately, it provides a much-needed respite from the constant pressure. Unfortunately, he meets a certain rabbit. One who threatens to break down Leo’s carefully crafted facade with a buck-toothed smile and a pat on the arm.
What’s a turtle to do?Usagi is at the Battle Nexus to avoid his problems, but unfortunately the tournament keeps giving him new ones.
He’s fallen head over heels for someone it’ll never work out with.
Again.
Except… there’s something different this time.
Maybe it’s fate, or maybe he’s just being an idiot. Either way, can you really blame him? That turtle is just so handsome!OR:
Leo goes emo, sells his soul, and proceeds to have the biggest gay panic of the century over a guy he met like a month ago.
Usagi is a dumbass bisexual, as per usual. he wants that cookie BADCW in the tags + AN

Summary
After Leo is saved from the Prison Dimension, his brothers quickly realize that more happened than they had realized. Leo would get random bouts of feral bewilderment and had random triggers that had not been there before. What had happened to him?
Gaichū doesn’t understand what happened. One moment he was in his home, running away from a beating from Master and the next… well… the next he found himself in a strange new world surrounded by new enemies who seem to know him. Now he has to learn to navigate the peculiarities of this new place and hope Master won’t find him.
Peculiarities such as gravity.
And light.

Summary
The function of a family was new and foreign, yet also very familiar. Unlike Casey’s ass of a father, Master Splinter never yelled. He calculated every word before he said it. He was direct, deliberate, gentle. It was a gentleness that Raph had trouble adjusting to, but eventually he came to crave Splinter’s calmness, so strongly contrasting his own stirring thoughts.
Leonardo, though. That guy was an ass. A stuck-up idiot who hung on Father’s every word and hardly left room to think for himself. But he was dedicated. He fought like a demon, the fire in his eyes burning with each slash of his sword. Raph respected him. Understood him.
Michelangelo was also easy to read: another idiot, too innocent, too optimistic. Fast, too. Insanely talented, more-so than even Leo (though Raph would never admit it to either of them). Mikey made sense, because you knew what to expect from the guy.
Raph liked to think he was good at figuring people out. A quick learner, right?
But Donatello…that guy was a pickle and a half.

IDW Raphael reflects on his relationship with his genius brother, who's facial expressions leave something to be desired.

Summary
Being the leader has always put Leo in the spotlight — but when the Foot Clan realize taking him down is the fastest way to break the turtles, Leo becomes their number-one target. A mystic curse leaves a mark burning across his shell, designed to weaken him with every fight, and the enemy taunts that if the head falls, the body will follow.
But the Foot didn’t count on one thing: Leo’s brothers don’t crumble without him. They rally, they fight, and they protect — because no one gets to break Leonardo. Not while Raphael, Donatello, and Michelangelo still stand by his side.

Summary
Leonardo's fight with Oroku Saki leaves him badly wounded, and in desperate need of medical care. Casey commandeers an old friend to save his life.
*Roughly follows the TMNT 2003 series, though it will be out of order. In typical fashion, it's a polyamorous-reverse harem fanfic, though that's limited to the turtles and a singular OC. And, because honestly its what I think listening to the show until it reminds me, the turtles are in their twenties.
