Summary
Splinter ripped his gaze away from the stomach turning scene and kneeled down on shaky legs so he could hold his child- probably for the last time. There was no point in taking Leo home to the med bay…even if the slider somehow survived the journey, the damage that had been punched into him was unsalvageable.
Leonardo Hamato was nearing the end of his life.
Splinter choked on a sob at the realisation, at the realisation he would outlive his own child, at the realisation Leo never got to truly live at all.
Or: Leo's last moments spent with Splinter after being rescued from the prison dimension + a turtle tot flashback

Casey Jones in Lou Jitsu: Punch Times 2!! by CraftyKat147
Fandoms: Rise of the Teenage Mutant Ninja Turtles (Cartoon 2018)

Summary
Casey Jones was an expert time-traveller at this point, but that didn't mean he wanted to do it again. Now, Casey Jones Jr is stranded in Hollywood in the 1980s until his family can find a way to get him back. Now he just needs to sit tight and try not to change history.
Lou Jitsu may be a skeptic, but even he can recognize that there's something strange about the newest stuntman. The kid has the reaction times of a veteran, the excitement of a tourist, and is as nervous as one of those little Chihuahuas. Even weirder is how familiar the kid is. One thing is for sure, Lou Jitsu will figure out who Casey Jones is by the end of their filming if it's the last thing he'll do!

Summary
Failed actor Lou Jitsu's life is not going great when said failure came from a marriage proposal that landed him in the Battle Nexus. Luckily, there's a goat man who's going to let him out, ruin his life even more, and saddle him with kids that he's now responsible for ... and it all goes downhill from there as he loses some of the kids he's risked everything to save.
(Also known as, this is a separated au, except I add things I personally want to see more of in the fandom.)

Summary
A vida do Mestre Splinter nunca foi normal: ele já viveu situações das mais inusitadas às mais trágicas. Mas nada o preparou para descobrir que Hamato Miwa — a filha que ele acreditava estar morta — ainda estava viva. A filha de seu inimigo mortal… é, na verdade, sua própria filha. E, como se não bastasse, Leonardo já havia confessado estar apaixonado por ela poucos dias antes da revelação. Dividido entre lealdade, culpa e o medo de machucar aqueles que ama, Splinter enfrenta o dilema mais difícil da sua vida: como contar a verdade ao filho sem quebrar seu coração? Como aceitar essa nova realidade, esse novo modelo de família, sem desmoronar?"

Summary
Splinter had never intended to be a parent.
Because really. Lou Jitsu? A father? A dad? Pigs would fly sooner!
And yet…
He didn’t regret it. Never, not for a moment did he regret keeping them. Loving them, as best as he knew how, which wasn’t very well at all. But he didn’t regret it.
And yet.
And.
Yet.
It was hard to love anything when he fundamentally, full-heartedly, unflinchingly loathed himself.

AMERICA PARTY 🦅 by clairakitty, MelonPalooza

Summary
Yoshi meets someone who lives in a completely different world than his own. Not many people catch his interest—it's rare for him to meet anyone outside the clan at all—but he's especially drawn to the magnetizing Tang Shen. Which is probably why it was a little too easy for him to accept the invitation to a party that is completely out of his comfort zone. There's loud music, lukewarm beer, and too many people.
Also, his brother is there.

Summary
His fingertips traced the glossy pages as he flipped through the book, the chaos of his mind calming instantly. His favorite painters, the greats whose names sounded like music to him, were all here: Leonardo, the master of secrets; Raphael, whose Madonnas pulled at his heart; Donatello, whose sculptures seemed alive; and Michelangelo, the divine perfectionist.
For a ninja heir, a book like this was a distraction; for Yoshi, it was oxygen. Deep down, Yoshi knew he’d never be able to fulfil his dream of creating art, not in this universe anyways. Perhaps, in his future, he can name a son after one of his favorite artists.
-
Or, a character analysis on why Splinter chose to name his sons after Renaissance artists, and analyzing the connection between each turtle to the artists they were named after.

Summary
“Go in with your brothers. I'll text you if April is here,” Splinter reassured, unbuckling his seatbelt and locking the car doors.
“Nah, it's fine, Dad. I'm still too nervous about this whole ‘school dance’ thing to step inside yet.”
There was a pause before Leonardo spoke up again.
“Plus… I wanted to give you some company. You've been pretty lonely without Scumbug.”
Scumbug.
As soon as that name reached his rat ears, a flood of memories hit Splinter.
Splinter loved Scumbug…
———
After a recent breakup with Scumbug, Splinter can’t see to get a grasp on things. Life is spiraling. He wants to be there for his sons, fulfill his role as a good father, but nothing seems to go as planned. Just when he thinks he's hit rock bottom, a certain middle-aged woman— that you, the reader, knows of— waltzes in with the potential fix for it all.

Summary
— Давно уже маленькие черепашки не звали меня посреди ночи, — пробормотал Сплинтер, оглаживая его лоб пальцем там, где его не закрывали бинты. — Обычно вы готовы перегрызть друг другу глотки за безраздельное внимание Красного.
Это было шуткой лишь наполовину. Леонардо поднял на него остекленевший взгляд. Было сложно просчитать, какая часть разговора застревала в его голове и проходила обработку, а какая вылетала во второе ухо, солнышком прокатившись по заторможенному лекарствами разуму и не зацепившись.
И затем Леонардо произнес:
— Он меня ненавидит.
— Пардон? — недоуменно переспросил Сплинтер.
Его сын моргнул, и наконец слезы полились по его щекам, смачивая бинты.
— Он меня ненавидит, — настоял Синий. — И он прав. Это я во всем виноват. -
