    NEON - A Separated Siblings AU by

    Summary

    For sixteen long-ass years, I have believed that I was the sole surviving creation from one of Draxum’s greatest failed experiments. At least, that’s what Pops had always told me.

    Now color me surprised, when I found out that there are three other turtle mutants and they have lived in the upper human city, all this time.

    This revelation is just the beginning of my story. It’s one full of chaos, explosions, existential dread, pizza, parental issues, drinks, double-triple betrayals, and generally bad life choices that make me question where I fit into this world. Maybe there’s a great destiny waiting for me out there, or maybe I'll get myself killed while I’m still figuring it all out. At least, it seems I’ve found a new place I can call home, and that counts for something... right?

    (This fic is loosely inspired by AU designs by Shanzepoo on Twitter and a few scrapped concepts for seasons 1 and 2 of the series)

    Summary

    AN UPDATED VERSION OF ONE OF MY FANFICS

    After a messed-up patrol, leaving Mikey injured because of the three brothers' actions, Splinter punishes them from going to the surface until they can learn to work and adapt with Michelangelo together.

    It is then that Donatello created a drug called the BIO (Bionic-Intelligence-Organism) that boosts Mikey's intelligence, his behaviour and his strength.

    Hoping that this would lift the punishment, the three brothers went along with the plan and tricked Mikey into eating a pizza with the drug in it, and soon the formula worked

    For the time being, the BIO transformed Michelangelo for the better as he is more mature, a lot smarter, stronger and even better at things

    But as the drug gets stronger and stays longer in Mikey's system, it begins to turn him into a different person, something cold, something opposite of who Mikey is...Something sinister

    Will the family find a way to reverse Mikey back to his natural self or will this dangerous new Mikey be their downfall?

    Summary

    “I feel something.” Mikey says. He sounds serious. Stern. “Someone’s here.”
    Uh yeah. Leo. In his own room, which his brothers didn't ask to do cult shit in, by the way. He tries to voice this but his words don't sound, though he knows he’s saying them. None of them turn around.
    “Alright. Now or never.” Raph says grimly, and they let go of each other’s hands and open their eyes. They don't look at Leo. Rude.
    “If there are any spirits here tonight, we are searching for our brother, Hamato Leonardo.” Mikey says, reaching out to cup his candle’s flame. It smells like the ocean, and Leo can appreciate the use of blue candles if the seance is for-
    The seance is for him?
    ___
    It's hard to make peace with your death, but Leo did it anyway. To protect his family, to protect the world.
    He finds it quite a bit harder to make peace with what comes after death.
    .
    A Halloween special that ended up being more sad than spooky. Enjoy!

    The last of Casey Jones' family died less than 48 hours ago. Now that the world isn't about to end he may need to start processing that, but that's hard and it's easier to pretend everything is okay. Being the only one to remember the last war to ever happen is totally okay. To be a sixteen-year-old war veteran is totally okay. To be face-to-face with the younger versions of your deceased family and realize as much as you love them you are just the cool guy they just met, is totally okay. Yeah. Yeah. Casey Jones is totally okay.

    The world ends. The Krang win. Leo failed.

    It was supposed to be on Casey's shoulders (and his shoulders alone) to go back and make sure the invasion never happened in the first place, but apparently his student had a little more inherited stubbornness than he'd thought.

    (Leo ends up in the past. This changes some things.)

    Summary

    A rottmnt Leonardo-centric angsty tear jerker.

    Sometimes tragedy can split a family apart.

    And sometimes it can bring them back together again.

    If it isn't already too late.

    Leo was rescued on the same day he went into the prison dimension. Wasn't he?

    And nothing bad could possibly happen from being shoved into and ripped out of an alternate dimension.

    Right?

    -or-

    Leo is pulled through Mikey’s portal after seven long, grueling years trapped in the prison dimension with the merciless Krang Prime, only to discover his brothers who he desperately missed for all those years not only didn't have time to miss him because it was only two minutes for them, but they are also angry with him for so quickly and willingly sacrificing himself to save everyone, instead of coming up with a better plan all together.

    One tragedy rips the family apart but another has the potential to bring them back together again when Leo turns to Draxum for help and they discover he is suffering ill effects from his time trapped away in an alternate dimension. But will he be able to reunite with the family who pushed him away while there is still time?

    Or does he even want to?
