    Summary

    One restless night, Leo's curiosities about Draxum's words leads him out of the lair. It's nothing special; a thin file, forgotten on a shelf and collecting dust.

    One restless day, as Leo cleans his room, he finds that very file. The invasion is over, all the major threats have been defeated... Leo can finally kick back, relax, and take on some leisurely hobbies.

    Leo never expected it to come to this. This role he'd taken on.

    Summary

    After having their music careers launched into the stratosphere by international superstar Baron Draxum, the Mad Dogs find themselves on the cusp of their first big tour. Their debut album has gone Platinum all over both the human world and the yokai world, their concerts sold out across the country and negotiations for a World Tour begun. It seems like Donatello, Leonardo, Michelangelo and Raphael are living the dream.

    Unfortunately, the curse of the music industry is doing what it does best and slowly chewing each of them up in different ways. The brotherly bonds that made their act flawless and powerful are starting to fray and put their barely beginning careers in danger.

    Particularly Donatello and Leonardo.

    Whatever is going on between the self appointed twins is coming to some sort of terrible head. Constant grandstanding has turned into bickering and on into straight up fighting. Shameful feelings neither of them want to admit to or deal with are bubbling beneath the surface and causing both of them to lash out in anger, threatening the team even further.

    Just the way Draxum wants the last surviving members of the great Hamato Clan to stay.

    “What do you mean? Who’s your sensei then?” Mikey asks.

    “Master Leonardo!”

    “Who?” Raph asks, bewildered.

    “We don’t know anyone by that name.” Donnie adds with a raised brow, everyone nodding in agreement.

    Casey blinks at them, utterly baffled.

    “But Master Leonardo… is your brother.”

    Summary

    Winter is settling in, the air becoming nippy and cold, sinking deep into Leo's body. He doesn't move an inch.

    'How long does it take to freeze to death?' Leo wondered, tucking his arms closer to his body, 'Ages probably...'

    He should go back, really, it was getting late. They'd be mad at him for being out so late. He was always messing up, so it wouldn't be any different than usual. He knew he was a headache. Maybe it would be better if he were-

    .

    It's been years since the almost apocalypse happened, all their wounds were healed and tough talks were had. So why is Leo feeling like this? What is wrong with him? Everything is fine! Why can't he just enjoy this happy ending like he's supposed to!? Utterly sick of his broken brain, Leo goes on a quest to figure out what the hell is going on with him and to fix it once and for all.

    Warning!! This fic deals with suicidal ideation! PLEASE take care of yourself!

    Summary

    “But don’t you know?” she asked. “Can’t you feel it? Did it get lost in that big heart of yours? One of your children is waiting for you.”

    Yoshi jerked as if electrocuted. She couldn’t mean to say what it sounded like she was saying.

    That tiny fourth turtle with the blue-patterned shell and bright gold eyes—the first one to smile and reach up to be held, the one that had fallen during their frantic escape and was left behind in the crush of the destroyed lab—the one the little shrine in Yoshi’s room belonged to, even though he didn’t have a proper photo, or a decent idea of what Blue would have looked like grown into personhood—the one that a corner of Yoshi’s heart belonged to, even now, even still—

    “He’s alive, my darling,” his mother told him. In the dream, she sounded so certain. The clan symbol on her obi seemed to glow, a warm, shining thing that cast all darkness and doubt aside. “Go and bring my grandbaby home, okay?”

    Or: Leonardo grew up in a Hidden City orphanage, but he had a home waiting for him all along.

    In order to achieve your goal, you'll have to tredge through your senior year and a lame job at Pizza Wizza until you have the means. It's a shame one of the weirdos you deliver to asked for your PlayStation ID, because you could pinpoint that moment to when everything started exponentially going wrong.

    Between the mysteries shrouding the hidden city and yourself, the turtles find that there's as much to learn from you as there is from them. Especially when a new threat is revealed in the yokai underground.

    Summary

    You wake up in an unfamiliar mutant's body and the others around you keep calling you Donnie. You try to blend in but that quickly becomes too hard after a mission gone wrong. Luckily, you're able to return to your own body after a while and the body swap fades into your faint memory. But next month, you've swapped again.

    You and Donnie body swap once a month, you don't know why or how this keeps happening. You need to work together to figure out why.

    First time writing the turtles, bear with me! :)

    *I've made the reader as GN as possible, so some parts may seem vague when describing your body.
    **Complete, but I will be going through and editing and fixing a few small details!

    Summary

    You've known the brothers for three years now, and in those three years they had all reacted to your bouts with migraines in different ways. Raph worried and texted you well wishes. Mikey sent you little doodles of art. Donnie had caffeine and chocolate delivered to your front door. But Leon? Leon was a different story all together. He never understood- until suddenly he did.

    You and Leo become closer than you've ever been, and it's getting harder and harder to ignore his charm. Not that you want to.
