Rest For a Weary Soul by Shattered_ontheInside

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).

Donatello Hamato: A Pizza Topped with Soulmarks by CraftyKat147
Fandoms: Rise of the Teenage Mutant Ninja Turtles (Cartoon 2018)
29 Sep 2025
Tags
Summary
Donatello Hamato was among 8 other soulmates. He was statistically lucky enough to have already found 4 of them which left 37.5% undiscovered. Considering the variables it was highly likely that they would find their soulmates sooner rather than later, especially considering the various efforts of his brothers. Until then, Donnie would work figuring out where they came from and how to keep them all alive. Newton knew Leo could only patch them up so many times. ... (Note to self, look into prosthesis and various prosthetics. Ask Leo for help with the squishy bits. *shudders*)
In Which, Donnie unfortunately does not conquer the world, nor acquire Uranium but does manage to find his remaining soulmates, fend off a 'fish'cious fish monster, acquires minions, and fly a spaceship. And maybe just maybe call Leo his twin.

He shouldn't have been here in the first place. But he feels like he could make a difference. He has a right to. But the others don't see it that way and wish him dead.
It's too late, because with his newfound past, no one will accept him and he's forced to leave his current home.
..Where will he go now?

Summary
Pretty much just what the title says. Mainly 2012 turtles, but I’ve got some 2018/2003 in the works. Maybe even Mutant Mayhem one day!
It's a series of OneShots/Drabbles that may be focused more around Donatello than other ninja turtles because I find a mini Dee absolutely adorable!
Feel free to drop requests for him or other turtles as tiny tots and I’ll see what I can do!

Summary
"It is bedtime, Blue. Not talking time!"
"I know, Daddy," Leonardo says, exasperated, as if he does not confuse the two every time his head hits the pillow.

Summary
“Where we at with contractions? How long between?” Leo asked as he knelt to swiftly undo the loose ties at Donnie’s waist, shedding the wet fabric down his thighs and off from around his feet.
“Two minutes, give or take.” Donnie managed between gritted teeth before another contraction stole his breath, unable to stop himself from curling forward as much as his stomach would allow, hands returning to brace against the bed. His stance widened as he tried to sway his hips against the pain.
Donnie shuddered as another trickle of fluid streamed down his thigh. Leo leaned down, tracing the flow back up between Donnie’s legs until he could see—
Holy shit.
Leo straightened, moving onto his feet. “Okay, looks like we’re definitely having some babies, baby.”

Summary
The lab explosion still haunted Splinter, even seven years later. It wasn't because of the damage, or the trauma, though those were a big problem.
No. What haunted him most was the loss of one of his sons. A little turtle with red and yellow stripes. Gone, in a flash of orange fire.OR
