Summary
His attention was shifted to his big sister, who, instead of working her way up to her feet, stood on all four legs with such ease, like she’d been quadrupedal for her entire life. Now that she was up Mondo could see how different she looked—spikes infected her back and tail; thicker, shorter limbs; and elongated claws that ripped straight through the rubber of her boots. Her goggled eyes were locked on Mondo and something steadily dripped down her chin.
Drool.
Mondo didn’t know how this day could get any worse.

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.

Summary
Reunited with a family she doesn't remember, Giovanna "Vee" wakes up a stranger in a strange land. The boisterous love of her newfound brothers feels alien and overwhelming, and every attempt to connect pushes her further away. A fragile, unexpected bond forms with the one person who understands her silent need for order in the chaos—Donatello—but it's a single point of light in a sea of confusion.
Meanwhile, the ghost that has haunted her family for thirteen years is given a name: Maximilian Armitage, a beloved philanthropist with a chilling connection to her past. A tense encounter at a high-society gala confirms Vee's worst fears, revealing the monster hiding behind a charming smile.
Seeking answers, the turtles are led to their creator, Baron Draxum, who reveals a horrifying truth: Giovanna wasn't just lost; she was the target. Armed with the knowledge that she is the key to Armitage's god-like ambitions, Vee is crushed by a terrible new weight—the fear that she is not a long-lost sister, but a curse that will bring destruction to everyone she has ever loved.

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 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.

Summary
"It's crying, what a baby! Gonna go cry to your kappa mommy, freak!?"
He was kicked again, hard in the shin, and the whole group laughed heartily, echoing in his tympana over and over again. He was going to die. His lungs desperately heaved in his frozen chest and he tried again to cry out, but all he could manage was a whimper. Shame rotted in his gut as stood there, useless.
"Hey!" A new voice yelled. "Cut it out!"
A human girl broke free from the bushes and stormed into the clearing, waving a baseball bat menacingly.
Oh no. It was her.
AKA An au where the rise bros actually ARE kappa yokai and they do not like humans very much. Don't worry, I think April might just be able to change their minds.

Summary
Leonardo was the Leader of the Turtles, the oldest brother and extremely protective of his brothers. He was a focused and extremely skilled ninja. That's what everyone thought Leonardo was, but in reality, he was a Female Turtle forced by Splinter to pass himself off as male. He was forced to pretend to have a deep, masculine voice, which caused great pain in his vocal cords, and he had to endure Splinter's abuse completely alone. Leonardo wanted to be feminine, to be called a girl, not to have to feel a horrible pain in his throat and, above all, not to have the name Leonardo, which every time it was said caused unbearable pain in his soul. And her life changed when she found an injured vampire bat in the sewers and took it to her room. What she didn't imagine was that this was the Heir to the Vampire Throne and that he was more than in love with the beautiful Turtle who saved him.
