    The Family's Sunshine by

    Fandoms: Rise of the Teenage Mutant Ninja Turtles (Cartoon 2018)  

    04 Jun 2026

    Tags
    Summary

    Whoever said that being the youngest was easy obviously didn’t grow up with three very overprotective older brothers. Actually, if Mikey was going to describe being the youngest in a word it stunk!

    No one ever took him seriously, especially not Raph. And even though he loved his big brothers – he got tired of them babying him all the time. Truth be told he had been fighting being the ”baby” of the family from the time he was seven, but here he was eight years later and still trying to get his brothers to see what he was capable of.

    Tapping Out by

    Fandoms: Rise of the Teenage Mutant Ninja Turtles (Cartoon 2018)  

    16 Jan 2023

    Tags
    Summary

    He waits until Leo is finished catching popcorn from Mikey’s tosses, then subtly touches his forearm.

    Three quick taps. Then three slower. Then three quick again.

    It’s a simple code, but it means something specific to the two of them: that Donnie needs out of here, and it’s on Leo to make that happen.

    Five times Leo comes to Donnie's rescue, and one time he returns the favor.

    Our Connection Through Death (or Space and Time) by

    Fandoms: Rise of the Teenage Mutant Ninja Turtles (Cartoon 2018)  

    23 May 2026

    Tags
    Summary

    It's been two years since Leo died.
    But now, Mikey had to find out the truth; there is no Leo anymore. His soul had not reached the ancestors.
    It's not an easy feat, to accept that you will not reunite with your brother, not even in death. As feelings clash and tensions are high, maybe miracles can be born in the pain and suffering.

     

    or; maybe some things are not as lost as we thought they were

    Let Me Bring You Honor by

    Fandoms: Rise of the Teenage Mutant Ninja Turtles (Cartoon 2018)  

    14 Dec 2022

    Tags
    Summary

    Donnie may have been somewhat oblivious, especially when it comes to less tangible concepts such as ‘emotion’ or ‘honor’ but even he picked up on some things.

    His family, the Hamato clan, valued honor and loyalty. They were ninja’s after all. Donatello might not have always belonged, but all his actions reflected on them. Even his final ones.

    Suicide, taking ones own life, was not an honorable thing.

    But the thing about life, something that always frustrated him so, was that every rule had an exception.

    Or-Donnie attempts Seppuku, but it doesn't go as planned

    Tags
    Summary

    It's always been easy to dismiss the problems that they see in Mikey. Unfortunately, however simple it had seemed, ignoring a wound just lets it fester and grow, until it's too late to heal. When they start to see just how bad they've let things get, Donnie, Raph, and Leo just hope that they can still fix this.

    or;

    Mikey is not treated right by his family, and they finally realize just how bad it's gotten.

    Atrophy by

    Fandoms: Teenage Mutant Ninja Turtles (TV 2012)  

    28 Sep 2022

    Tags
    Summary

    Hamato Michelangelo was not quite the energetic ball of sunshine everyone had dismissed him as. Not like he wanted them to think. That he had fooled them to believe. Alone now, in his room, he sits with his back to the wall, with his kusarigama in hand, and he thinks. About his life. About the way he's treated. About what is really worth this emptiness that has hollowed him out.
    He makes a decision. One that, as intended, was irreversible.
    And maybe in that, as the story of his life closes out, he would finally find some semblance of peace.

    Summary

    “He’s gotta be around here somewhere, I just kno-“ he suddenly tripped over an object buried in the snow.

    “GaH!” Leo shuddered, pulling himself up quickly and brushing off the cold substance.

    “Leo???”

    Looking back to see what it was that caused his fall, his heart nearly launched into his throat. “Oh no.”

    “Leo, what’s wrong?!” Raph’s voice echoed again from the phone.

    Leo got onto his knees, ignoring the cold snow that he initially was avoiding. He anxiously brushed away a few inches of loose fluffy snow to see the familiar pattern of a shell. “Shit-“ He muttered under his breath “Get Donnie and come to my location now!”

    “What’s going on?! We’re on our way now!” Raph sounded like he was already running.

    “I found Mikey.” Leo’s voice cracked as he hung up the phone before Raphael could respond.

    Three fingers, larger than he remembers. Greener than he remembers.

    No way is this his hand.

    But it follows his commands, pulls away when he tells it to, and. And.

    And it’s shaking, just like he is. All over.

    TL;DR Casey encounters an oozesquito. It all spirals from there.

    Summary

    Everyone loves Mikey. But is that always a good thing when some of those people are the bad guys as well?

    Maybe being the cute one isn't all that it's cracked up to be.

     

    A place for more mature one-shots that are Mikey-centric.

    2024 Update:
    *Looks like AO3 will be changing the tag verbiage for Underage to Underage Sex. It doesn't exactly fit to what I have or want in these stories so I am removing it but be warned there are a few chapters dealing with Mikey and his brothers being underaged*

     

    If you don't like, then please don't read. This will contain multiple different pairings with Mikey, and some many may not like. You have been warned.

     

    *Seriously, if you don't like or can't handle this type of content, then don't read it. You're only doing yourself wrong if you read something you don't like. Nobody needs that negativity. If you can't say something nice. Then don't interact with it. There's a reason why this is rated MATURE. It's for MATURE people only.*

    Summary

    Leo expected it to be a rat, but when he looked down he saw four tiny turtles covered in bright green ooze.
    They looked up at him, eyes pleading, and something twisted in Leo’s gut. This was odd. So very odd.

    -or-

    Rise!Leo accidentally replaces Splinter in the Mutant Mayhem verse and he becomes the MM!Turtle's adoptive dad.

    The Eldest Brother by

    26 Oct 2023

    Tags
    Summary

    2012 x 2018 X-over. No knowledge of 2012 needed to read

    In which Rise!Raph goes full older-sibling over Season 1 2012 boys, so we have our 12!turtles learn healthier communication & ways to express their emotions <3

    A Tumblr description I saw and liked: "It's basically Rise!Raph looking at the 12!Turtles and saying: Wow, you guys look like you need an older brother. I'm taking that spot!"

    Alternatively: In which Rise!Raph can’t get a break from his brothers, not even in a different dimension, and they sort of adopt each other. The family tree is getting harder to explain!

    No bashing, Rise! and 2012 have different circumstances and upbringing. Please mind the tags! RiseAU & the disclaimer note.
