A Rat's Nest by pluvio
Fandoms: Teenage Mutant Ninja Turtles - All Media Types, Teenage Mutant Ninja Turtles (TV 2012)
27 Feb 2024
Tags
Summary
Yoshi could see them still, the soft, gentle features of his wife and the beauty their daughter inherited from her. He could practically feel still the way her hand fell over his forearm, warm and knowing. How their child felt nestled in his arms. Their smiles had been so beautiful.
He didn’t even have a moment to say goodbye.
A small hand fell on top of his quivering snout. His eyes blinked open to see one of the turtle creatures staring back at him. Behind it, the three others were staring as well. Their tiny, dark eyes set in impossibly full cheeks blinked with concern.
Despite it all, Yoshi found himself with a gentle, unsure smile.
( or: splinter is suddenly a dad again after the loss of his wife and child and he has no idea if he's ready for it, but his immediate love for the four tiny turtle babies thrust into his care is not going to give him a chance to rethink )

My Sons, My Masterpieces by fantasticfourfoodgroups
Fandoms: Teenage Mutant Ninja Turtles (TV 2012), Teenage Mutant Ninja Turtles - All Media Types

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.

Splinter has had his four sons for a year now. He’s been adjusting well enough he thinks, what with the grief of his wife and daughter still looming over his head.
Then something happens during a supply run, something he never expected. He finds another mutant turtle, just like the ones back home.
Except he’s different.
And Splinter feels an overwhelming sense that he doesn’t belong here.
Even so, he does his best to raise him as his own.

Rest For a Weary Soul by Shattered_ontheInside
Fandoms: Rise of the Teenage Mutant Ninja Turtles (Cartoon 2018)
03 Oct 2025
Tags
Summary
Hamato Yoshi had done many things in his life that led to regret, but none so much as the ones that led to this isolation that surrounded him now.
He had let himself become entrapped in the matters of the heart which led to his literal entrapment under the power of the one he had come to deeply love - the one known as Big Mama.
He had never before felt like this - had never before considered the possibility of opening up his heart to another ever since the tragic death of his mother, who vanished before his eyes when he was but a young boy, to join so many before her in their ancestral battle against the forces of evil.
And that was what led him here - a man no more, but a monster (at least in his eyes).

a bigger heart grew back by taizi for GibbousLunation
Fandoms: Teenage Mutant Ninja Turtles - All Media Types, Rise of the Teenage Mutant Ninja Turtles (Cartoon 2018)
09 Aug 2024

Summary
“It has been a long time since a sick little turtle has called for me,” Splinter murmured, stroking Blue’s forehead around the bandages. “Normally you are all ready to fight each other to the death to monopolize Red’s attention.”
It was only partly a joke. Leonardo gazed up at him, eyes glassy. It was hard to gauge how much of their conversation was sticking the landing and how much was somersaulting straight over his sluggish head.
Then Leonardo said, “He hates me.”
“Pardon?” Splinter said stupidly.
His son blinked, and finally fat tears rolled down his cheeks, soaking into bandages on one side, unchecked on the other.
“He hates me,” Blue insisted. “He’s right. It was my fault.”

Summary
It's Christmas Eve, and Old Saint Nick is coming to town! Maybe he'll even swing by the sewers and leave something good for four small mutant children who'd do anything to believe in something.
But only if Splinter can break out of his slump first.

Sometimes Hamato Yoshi forgot that there was a reason to get up in the mornings.
But never for long.

Summary
The boys grow. They become little people, with their own thoughts and personalities and habits.
Yoshi is surrounded by ghosts.
A character study of Splinter, and him seeing Saki in the turtles as they grow. Inspired by a moment in my other fic, Puppet Tightly Strung, but in no way dependent on having read that one. I'm just really feral over Splinter and the Shredder, okay? They were BROTHERS

Summary
“What brings four kappa to our home in particular, then?”
An excellent question. Warning Shen had gone… less than ideal. She thought Saki a good man, and though she was kind, she seemed hesitant to believe their claims. Yoshi knew him better; perhaps he had already noticed the darkness within him, and so would be more open to what they had to say? Leo glanced back at his brothers to find them all looking back at him. Awaiting his decision.
Leo sighed, meeting Yoshi’s gaze evenly. “We’ve come to warn you about Oroku Saki.”
Day 2 of Splinter Appreciation Week!!! Just a little "what-if" for Yoshi/Protect: what if the turtles had interacted with Yoshi during Tale of the Yokai?
