    Summary

    "I have something I wanna show you.” Donnie exclaimed. Donnie grabbed Leo’s hand and pulled him out of the room and into the hallway. Donnie had to shush Leo a few times, but they made it into Donnie's lab with no one discovering them.

    “Do the magic!” Leo said immediately after the door clicked shut behind them. He was almost jumping up and down in excitement.

    “Just wait, Leo.” Donnie grabbed his purple goggles, and then gave Leo his blue ones. Donnie then led Leo to a table where a small purple robot laid.

    “Nardo, meet Shelldon.”

    Summary

    There was a lot of mutagen and other sharp objects being dangerously launched around as Baron Draxum lair got destroyed.

    What would happen if some of that got into a certain Red Eared Slider eyes?

    Well it would make for one blind turtle and an interesting shift from canon that what it would be!

    Summary

    None of them spoke - neither the four in the room nor the figure staring at them, who audibly groaned at the sight of who, exactly, came to pay him a visit.

    ~▪️🔹~🔹▪️~

    Shortly after the krang invasion a portal accident almost killed one of their own, leading to accusations and lots of fingers pointed Leo's way.

    But he hadn't lost control of his portals once since before they defeated the Shredder. Why wouldn't anyone believe him!?

    That's all in the past now. Or so he thought.

    Leo Onii comes home to his mountain cabin one blustery winter night to find his three brothers and sister who he hadn't laid eyes on in six long years there waiting for him.

    What will happen next is anyone's guess.

    Summary

    Leonardo is dead.

    Or, at least, he should be. Instead, he is floating within a colorful vortex that reminds him too much of his own portals. He tries not to think too much about it. But, eventually he is forced to when the vortex spits him out into a world that used to be his home, many, many years ago.

     

    Or; the one where Future!Leo somehow managed to luck out on a one in a million mere millisecond chance of a freak glitch in the space-time continuum that sends him back into the present, where the Invasion has been successfully driven back. And it looks like it was a one-way ticket travel.

    Obviously, everybody is So Very Normal about this.

    Summary

    Leo didn’t like being the rational one. He was the face-man, the jokester, the instigator. Donnie was supposed to be the genius. The cold, aloof scientist who hated touch and emotion. It was obvious who’d be the logical one on paper.

    But Leo had always been smarter than he let on. Observant. Strategic. He noticed things before anyone else did. Including when his twin was coming unglued.

    Donnie liked experimenting, being theatrical and dramatic, and he was a middle child. Leo was too, but Donnie was, like, a different font of it.

    So between the observer Leonardo and the mad scientist Donatello, it wasn’t even a question of who.

    And Leo didn’t necessarily mind, or even truly fear anything, because he knew where Donnie’s morals stood. Donnie was mostly just a dramatic theater kid, he’d never kill anyone. Leo just couldn’t be too careful.

    So, when Leo saw it, that true, unbridled rage, seething in Donnie’s blood red and frost blue sharp eyes. The eyes that mirrored his own so clearly…

    He felt it.

    Summary

    -or-

    A story that focuses on Leo and Donnie’s twinship after the Kraang invasion, and how they heal together

    Summary

    Separated as freshly mutated baby turtles, Leo (aka X, aka Experiment Alpha 002-2) is raised by the great and powerful Baron Draxum, to be the warrior he was designed to be.

    A few years later, when Splinter's three sons are turtle tots, their father reveals to them that a fourth brother perished in a fire; and Donnie tells his dad that he dreamed about this fourth turtle.

    Fast forward to the present, the three turtles are bumbling teenage ninjas who get in the way of the powerful Draxum. His ninja assassin is ordered to deal with the medddlers, and during combat the caped, masked ninja is surprised to discover the mutant turtle from his childhood dreams is not only real, but also his very own brother.

    X wants to draw close to his brothers, but the slider's only father-figure wants them dead, after they refuse to join him and subsequently destroy his lab.

    Thrown in the middle of two worlds, will X carry out the will of his master, or will the lives of his family be precious in his eyes?

    Also, as time progresses Leo must find the answer to some hard-hitting questions, such as: Who can he trust? Who is steeping him in a cesspool of lies and deception? And...

    Where will his loyalties lie?

    Summary

    Finally, finally, they spotted two blurs of color in the dull tunnels. Both were bundles of blue and green, but one had a splash of purple on his head. There was no longer a pair of voices. Instead, all they could hear were frantic chirps, churrs, and whines. They silently inched forward, straining their senses to get a better feel of the situation.

    As they got closer, they noticed with guilty dread that the littler one was not moving.

    Alternatively:
    During winter, when the twins were just young turtle tots, Blue and Purple got lost in the sewers. One doesn't make it... but they both end up finding their way back home.

    This changes everything and nothing at the same time.

    Summary

    “Oh, and Leonardo?” she calls once he reaches the door, voice light and dainty once again.

    He stops, fidgeting with his hands and turning back towards her, then replies as steadily as he can, “Yes, Mother?”

    She’s facing the window now, her profile grave and stark in the low light. Something bright and golden catches his eye, and he glances at a few locks of his own hair caught on her claws, drifting limply on the slight breeze from the window.

    “Never,” Big Mama growls, the sound guttural and beastly and everything she is deep inside, “ask to leave”—she turns her head to face him, her eyes glowing from the slight darkness, blinking one by one—“again.”


    Or, a Tangled AU featuring blonde Leo, Mother Gothel Big Mama, and plenty of angst and shenanigans.
