Mikey's heart rate shot up as he saw Leo, only one side of him visible. Leo took a step and Mikey's fight or flight kicked in. Leo flicked on the light, confusion on his face, both arms in view.

Don's breath caught painfully as he tried to breathe. He wasn't sure when he realized that he was lying on his side, staring at a spread of glass shards, that glittered in the meager light. Don tried to shift, only to feel the scrape of glass below him. Breathing hurt, his head hurt, and moving hurt. Whumptober 2023, Day 22

Due to his father's secret about his origin, Donatello's life seems to take an unexpected turn as he finds himself being targeted by the Shredder himself.

Mikey gets himself in trouble. For Whumptober 2023 #18 "I tend to deflect when I'm feeling threatened." Blindfold

"So, my purpose is most likely bait. I assume you're not leaving me in good condition," Don said. "I'm glad to see we're on the same page," Hun said. "It's simple. All I want is information." Don's eyes narrowed. "We all know I'm not going to tell you." Hun's smirk grew. "I've recently taken an interest in various torture devices. Let's try some out." Whumptober 2023, Day 18

Will he tie up those frayed threads or will resentment still linger? And what of his family's ever-aging mortality? The final fic in The Soul Collector Arc.

Oh, and Leo gets thrown through a window.

Don doesn't remember where Draco and the Daimyo's son sent him. He doesn't care to, either. But suffering of that level will not stay suppressed forever. Little signs show in the ensuing weeks, until it can't be suppressed anymore. Whumptober 2023, Day 15

(Part of the TMNTaC series) Being an older sister to four brothers is an adventure in and of itself.

What else can I say except "Booyakasha!" (Apritello)

In a bid to keep some technology out of Foot hands, the brothers have set up a scheme for Donnie to steal it. Unfortunately, things don't go according to plan, and now Donnie is poisoned, trapped, and hiding, trying desperately to hold until his brothers can get to him. Whumptober 2023, Day 14

Taylor's decision not to move out seemed like the right one at the time. She never considered that the turtles and April would want to stay in each other's lives - or that she might have to choose between a safe life and an extraordinary one. Sequel to "Raphael's Big Mistake".

Mikey likes to complain a lot, especially when he doesn't want to do something. So, it's no surprise that his brothers don't completely believe him when he says he doesn't feel good. To bad this time they should have listened. Whumptober 2023, Day 13.

Michelangelo is the goof, the comedian, the joker. But he is so much more than that. Like the wind, he is wild. He is fast. He is strong. This is what he brings to the table.

Don always thought that he knew what to expect if he was ever captured by the Foot. And while, at first, things went according to his expectations, they soon didn't. But there was no way he was prepared for the plans that the Shredder actually had for him. Whumptober 2023, Day 11. Not a happy ending. Mind the notes.

Siempre oímos a quienes nos rodean pero ¿los escuchamos?, vemos pero ¿observamos?, en fin, tú me dirás ¿cuál es la diferencia? Sin embargo, si yo te dijera que no es lo mismo, que cuando te dejas llevar las cosas se distorsionan y puedes cometer el peor error de tu vida ¿opinarías lo mismo? Un pequeño entremés, espero que les guste. ACTUALIZADO 11/Octubre/2023

Some new thugs grab Raph when they meant to grab Don. But while this is a case of mistaken identity, Raph will gladly take the hits, especially considering Donnie's current state. An AU. Part of Whumptober 2023, Day 9

Set during Rise of the Teengae Mutant Ninja Turtles Movie. Spoilers for those who haven't seen it. What Leo is going through as he faces off against the Krang.

Donatello makes mistakes just like everyone else. Only this time, his biggest mistake is catching up to him in the worst way.

But the voice that calls to him is too hard to ignore any longer.
