Summary
'' 'There's nothing greater than dying for a cause' – one of his great-great grandmothers, or aunts, or whatever, told him. But that just seemed like something a bitter ghost would have to keep telling herself.
There are many things greater than death.
Like waking up in his art room, his fingers stained and bright. Like getting a text from an old friend. Like getting to eat breakfast with his brothers, kicking each other under the table.
Like living.
Being a Hamato, Mikey thinks, seems like a rather horrible way to be. ''

Summary
“He says his name is Jotaro.”
Leo gave him time to elaborate. He did it out of pure habit and maybe to spite himself, because Usagi never elaborated.
“Okay. And where are Jotaro’s parents?” he asked, waving his hand in the air to indicate he needed a little more.
Mikey and Usagi exchanged a second look, which already promised complete disaster, so when neither of them managed a response, Leo walked over to the table and leaned over the child.
“Are you lost? You need help?”
Jotaro didn't even look up at him, fully focused on sucking all his juice through the straw at once, and when the carton finally emptied, he gasped for air as if he'd just drowned.
Or;
Usagi is ready for a new challenge. Leo is NOT.Series

Casey and Cassandra both get haunted by their past and then there's that weirdo named Bonesteel that is more involved in all of that than he knows ...Chpt. 33 and up: The war has finally begun: The dragons are determined to take the planet Earth back from the humans and will fight for it all over the world. Together with Usagi and his friends the turtles still look for the right battle strategy and there are some lessons that await Leo as a ‘leader in training’.

Also we learn how things came to pass 3 years ago, when Eddaneid kidnapped Mikey and led his brothers into a trap …I borrowed elements from various tmnt media and tons of mythology from all over the world.

Summary
Twenty-Eight years ago, Hamato Yoshi became Splinter. Twenty-Six years ago, he became Splinter, boss of the Underground. Seven years ago, he was pronounced dead within the Hudson of the upper city, alongside his adopted brother Oroku Saki, after having fallen from a high rise in the early hours of a winter morning. And fifteen minutes ago, what was left of his legacy was attacked by an unknown source, seeking vengeance for the murder of Hamato Yoshi.
The Underground is not a place that has your best interests at heart. And when Kingpins hands seize giving orders and when operations sigh into corpses overnight - someone has to go looking.

Summary
"Leonardo planted a light kiss on his boyfriend's growing bulge under his trunks as he groped his thighs. With his right hand, he reached under the garment and lifted the hardening dick and flipped it up. With his mouth, he kept relentlessly kissing and sucking on the other's balls."
Leonardo and Usagi wake up one morning, and thoughts about last night awaken a certain sexy feeling, and one thing leads to another. They have fun :)

Alright, team. New group chat. 🎉
Because SOMEONE (glares at Mikey and Leo virtually) kept clogging up the old one with GIF wars. 🙄Neon_Leon💅:
Uh, excuse me, April.
First off, they were strategic morale-boosting visual aids.
Second, my reaction time on that "dog with sunglasses" meme was legendary, tyvm.A chat fic with Leosagi, Timtello, Shellshocked, Aprinita, Rasey, and Raphmona. Filled with fluff and shenanigans with the occasional angst and drama.

Summary
Leo, 27 and still fated-one-less, had finally caved—signing up for one of those sketchy "Fate Hunting Consultation" services in a desperate bid for connection.
Then he showed up at work.
A new guy. Tall. Purple bandana. Sharp eyes and an even sharper tongue—like he’d been born annoyed at the world. And seriously? Kinda hot… in that I'd punch him then kiss him kind of way.
But Leo was sure of one thing: this turtle had zero charm, all ego, and absolutely hated his guts.
So when his heat hit like a freight train—sudden, violent, impossible to ignore—the universe really had a sick sense of humor.
Because the only person within reach?
Was him.
The grumpy purple pain-in-the-shell he couldn’t stand…
And who might just be his fated match after all.
(PS. This is my first story and I did not beta read this!! Also this is heavily inspired by "I can't believe You're my Fated Partner")

"Leo you- you seemed crazy, like under a spell or magic, brainwashed, or something" Raph voice trembled.
Leo popped his lips," Yeah, I think I was,"
Mikey quicky added"Why aren't you here, portalling away," almost rambling the last words in a plea.
"It connects to my nimpo powers or mystic energy or both? It's confusing," Leo admitted.
Donnie rested his hamds on his hips"Sigh, What are we to actually do,"
"I'll figure it out,"
Or: Yuchi is a desperate bitch, Leo is forced to deal with it. [Im not sorry]

Summary
‼️human au‼️
Leo and his brothers aren’t really normal compared to other kids. Not in a “i’m so quirky way”. More so a “hey so my ancestors have some kind of weird power that passed onto us???”. Plus with the way Leo looks unique compared to others, it makes it difficult for him to make friends.
Leo is out on a walk one night when a random person starts talking to him. This person would befriend him; Yuichi Usagi. Their relationship grows, both platonic and potentially romantic.
Things unfortunately go radio silent when an alien invasion takes place, and Usagi can’t get ahold of Leo.Leo has simply just disappeared. What happened?
