    The Greatest Thing We've Lost by

    Fandoms: Rise of the Teenage Mutant Ninja Turtles (Cartoon 2018)  

    17 Aug 2025

    Summary

    Leo waited. His leg was growing painfully numb under the ice. He wanted to rip the pack off and heave it across the room where it could shatter on the floor. Instead, he forced himself to stay quiet as he watched everyone disperse on their assignments, feeling his heartbeat inexplicably rise in his chest until he finally couldn’t stand it anymore.

    “And me?” Leo looked to Splinter. “I know portaling is kinda off the table right now, but, you know, plans are still kinda my thing. Just give me a minute—an hour max—and I know I can come up with a place for us to stay...” Leo’s voice faded as Splinter placed a warm pink hand on top of his own, making it lay still.

    “Do not worry, my baby blue.” He said, giving the back of his hand a pat, a soft smile reaching his furry face. “I know exactly where we will go.”

    ----------

    Leo knew losing an arm would be a hard change. He just didn’t know exactly how many changes he'd have to deal with. Turns out that narrowly avoiding the Krang apocalypse doesn't mean everything goes back to normal.

    (Or my traumatized turtle boys spend some time recovering in the countryside because the author was listening to Noah Kahan’s Stick Season album A LOT)

    Summary

    After being kidnapped by a mysterious organization, the Hamato brothers are separated and experimented on—physically, mentally, and emotionally. Each is told the others are gone. But what their captors don’t realize is that the bond between these brothers is more powerful than any chain, any scalpel, any lie. This is a story of resilience, pain, and the love that holds them together even in the darkest depths.

    Summary

    Leo's swords were gone, Mikey was down, and the wolves were about to attack his brother.

    Everything slowed down to Leo, as he looked on from his splayed out position on the ground.

    His heart pounded as he watched the wolves pounce.

    “No.” He whispered to his unconscious brother. He stood up as fast as he could and began running towards them. “No. No. No no nononono! MIKEY!”

    Summary

    “Let me give you some advice,” Leo said, still so quiet and cold, nothing like Raph had ever heard before, blue eyes burning like fire. “Don’t ever lay a hand on my brother again. I don’t care who you are. I don’t care how big you are. All I care about here is him.”

    Summary

    Months after the Krang invasion, Donatello begins to experience severe shell irritation. When tests reveal leftover Krang matter lodged deep in his shell from the Technodrome explosion, Leo and Draxum perform a delicate extraction procedure to save him. Recovery seems promising—until Donnie collapses weeks later and begins coughing up blood.

    After an emergency evaluation, Draxum delivers the devastating diagnosis: a rare, aggressive form of cancer, likely triggered by the Krang residue. As Donnie undergoes harsh treatment, Leo—driven by guilt, love, and fear—digs into his medical training, determined to find a cure. He refuses to let his twin slip away, even as Donnie weakens by the day.

    @everyone
    Whoever’s Mikey has been screaming in the ASMR voice channel for three hours straight, could you get him out?

    In universe 2003, Donnie tries to experiment with the inter dimensional gun the 1987 turtles had given him. Instead, he accidentally creates a multiversal chat room for many different versions of his brothers, and counting.
    It certainly makes life…interesting.

    TLDR: multiverse group chat between most iterations of the turtles. Starts with 2003, 2012 and 2018 but more are added as I go. 50% plot and 50% chaos.
    *now includes the 87, mutant mayhem and bayverse boys!*

    Summary

    “Technically, it’s Mikey’s fault,” Leo conceded, with half a smile. “But you’re welcome to pin it on me, your least favorite brother.”

    CRASH.

    Leo jumped a foot in the air, as Donnie’s toolbox hit the floor, halfway retracted into his shell and just barely caught himself from wiping out entirely. That should have been hilarious, except Donnie couldn’t think straight. He marched forward, heedless of the very rare and expensive tools being trampled underfoot, and met Leo’s wide blue eyes with his own glare. “What did you just say?” he demanded.

    ————-

    Leo, in all his self deprecating glory, thinks he’s Donnie’s least favorite brother.

    Donnie, personally, will not let that slide.

    Summary

    “Why did I say that,” Leo mutters. It doesn’t sound like a question.

    Donnie answers anyway. “Because you’ve refused every single one of my attempts to get you into therapy. Telehealth exists, Nardo. We’re on a very good insurance plan.”

    “Since when do we have insurance?” Raph says. He’s peering out from under the overhang into the rain, like maybe Mikey’s going to make a surprise reappearance. “Are you frauding some sleezy millionaire again?”

    “Just doing my part,” Donnie says mildly.

    Summary

    Two different worlds. Two different teams of siblings. One enemy that refuses to stay buried.

    When Raph vanishes through a crackling portal, her family discovers a nightmare they thought was over: the alien conquerors are back, their grotesque machines spilling across dimensions. A rescue mission becomes a race against time as the turtles search rooftops, shadowed alleys, and hidden realms where mystic power is stripped away — while Raph fights to keep herself from falling into the uncontrollable fury of her Savage state.

    But this battle isn’t theirs alone. Another team of turtles, older, battle-worn, and scarred from their own war with the invaders, is pulled into the chaos. Two generations. Two dimensions. And one impossible choice: trust each other, or watch both their worlds consumed.

    The portals are opening. The Kraang are waiting. And family may be the only weapon strong enough to survive.

    Summary

    Leo is pretty sure he’s dying…

    He’d like to say that he’s surprised, that he never expected to die so young, but then he’d spend his last words on a lie. 

    Blood drips down his plastron from the wound at a slow, steady pace, coating the claw impaling him a deep crimson.

    This is it.

    Leo floats and hurts and hurts and his head crashes against cold, hard rock and then it's dark—

    .

    .

    .

    —and Leo wakes up screaming.

    Summary

    Leo will be fine. Sure, he may have a big hole in his chest, and he’ll probably be out for the count for a while, but he’ll recover. He just hates that his brothers will be the ones to pick up his slack. He can only hope they’re strong enough to face the Godless on their own but he supposes it could be worse. He could be stuck in Neo Edo all alone, but thankfully he has Yuichi to keep him company. It won’t be all rest and relaxation, however. They still have the Council to worry about.

Also, small disclaimer, all the info I have about the 2012 show is from the wiki and some random memories I have from like, five years ago as well as random clips I see on Tik Tok and Tumblr.

    Summary

    Leo always protected them since he saw himself as the oldest, “If not me then who?” is what he would always say to Raph whenever he tried to get Leo to understand that none of the brothers liked seeing Leo take hits for them.

    “At least let me protect you,” Raph stated, trying to look Leo in the eyes as he avoided the contact.

    “I can’t ask that of you Raph,” he sighed as he stood, and Raph grabbed his hand. “You’re not asking.”

    ----
    After the S1 finale Leo does not come out of the wreckage like he originally does. Raph is lost because now he has to be the one to step up, but he can't find himself too. Until that night theres a crash in the lair and a familiar shadow is coming back home.
