A recovering Leonardo is a frustrated Leonardo. (Short one-shot set sometime in the beginning of Season 3)

Donatello discovers something shocking about Leonardo. Takes place during season 4 of the 2003-verse.

Donnie is determined to find a retro-mutagen, but doesn't notice that one of his experiments is starting to affect his brain. What would Donatello be with twice the intellect, but with a fading ability to tell right from wrong? And how far is he willing to go in order to create a retro-mutagen, or simply satisfy his curiosity…? /Nickelodeon. See Author's Note for details.

After thirty years, Leonardo needs to see Donatello's face again. A missing scene from "Same as it Never Was."

Donatello thinks you're never too old to learn something new. Leonardo thinks they're all just too old, period. Pre-SAINW.

Leonardo has come to a realization about who he is and who he wants to be. "What were you thinking pulling that Captain Ryan crap, anyway? This stunt almost got you killed today. Did it ever occur to you that Captain Ryan isn't real?" "I wasn't...Captain Ryan wouldn't." "Captain Ryan wouldn't what?" "He wouldn't have gone back."

Raph wants to ask Leo about something he saw topside. Turtle-tot, only T-cest if you really squint.

The rooftops sped by in a blur. His feet pounded the floor in sync to his heartbeat, both steadily gaining as he pushed himself to go faster. The footsteps behind him grew in number. The clouds shifted in the night sky, blocking out the moon's light. He stopped at the edge of the roof and knew the time for running had passed. [one-shot; rated T for blood; art by Sneefee]

Bodies of water were once doorways between this world and the next. Living in an old water treatment plant means being there when the doorway opens. Takes place during the last season of the NT in their new lair. No pairings, for you who've commented your fears otherwise. Just pure ghost story.

Don's duffel bag can be a bit of a nuisance at times, but there is a very good reason for him to carry it everywhere he goes. Rated for minor violence. One shot. 2013 TMNT Fanfiction Competition Winner - 3rd Place Category: Best Donatello. Preview image created for this fic by the very talented Sherenelle on DeviantArt.

Donatello, in his own small way, will never allow things to become the same as they never were. Vignette.

In hindsight, Donatello should have just gone into the dojo and avoided the unpleasant predicament in the sewers altogether. It may have prevented the Great Mop Attack in the very least.

Leonardo found it strange that he could forget those voices, those moments when they were all peaceful and laughing, yet he could never forget what it sounded like to hear his brothers scream. On the majority, a character study.

A little poker night fun and some light conversation. One shot.

Post Cousin Sid. What do Leo's brothers think when they see the damage inflicted by Leonardo's wounds for the first time. And what exactly is going through Leo's head?

Don has caught a cold but that needn't mean the lair has to fall apart. One shot.

Time hones Leonardo like a blade.

Leonardo leaps off of the Empire State building when he's thirteen. No pairings.

When the turtles find themselves unexpectedly transported to the other side of the galaxy, they're not sure what dangers they'll encounter, or what strange creatures they might meet, but they DO know one thing: it's all Mikey's fault.

Raph and Leo go for pizza, sadly they're too busy kicking butt to get there and it seems poor Raph's going to have one of *those* nights. Just a one shot working on the brotherly team dynamic, rated for some violence and a couple of bad words.

Last in the Bad Places trilogy. As nightmares walk New York's streets, Leonardo continues to lose himself in his warped genetics and growing violent urges.

*This happens when the Turtles are much younger* Mikey gets hurt during a sparring match and everyone freaks out, except for Splinter.

It doesn't happen very often, but this time Leonardo knows he is in Big Trouble. A Round Robin story brought to you by the Terrapin Tarts RP team!

The turtles face off against their most challenging enemy yet. In their minds, anyway. But the quest for perfect waffles was never an easy one.

"When he had hatched and lay exhausted he looked up into the face of another like him who had broken from his egg previously, one of four. Siblings, if a baby turtle could comprehend such a thing." One shot.

Hurt, trapped and alone. He could feel himself slipping...almost. Dedicated to the 29 miners that lost their life and the 2 that survived in the Upper Big Branch Mine, WV

This is how the "Shredder Strikes Back" episode should have ended! 100 word drabble for giggles. Please review!

Trapped in a building about to be stormed by a SWAT team, the Turtles face a terrible choice.

Something warm was slipping down his leg and he shouldered his way from beneath the burden at the same time a hand pressed to the asphalt and pushed back. When he looked, Leo was on his side clutching his thigh. It was bleeding. A lot.

Sidefling to "A Paper Wall". Two Turtles have a late-night talk. Absolutely not T-cest.

How do you heal a break? Can you fix it alone?

Or, perhaps more appropriately, the calm before the storm.

Leo really wants one of his favorite snacks. But he's going to have to get help from a certain brother if he wants to eat it.

The trick to it all is just saying it before you forget. Warnings: Death, angst. Set a few years after the CGI movie.

In which Raphael sees how horrifying war can be. Rated for character death, violence, and gore.

A KC drabble. April asks them why they wear their masks. A loud conversation follows.

Breakfast oneshot. Maybe Splinter really should consider the necessity of forbidding Donatello to read during breakfasts.

Simply put, Leonardo can't sleep. The remedy, it turns out, is fluff.

“You can learn all the crud you want to be prepared,” Raph tells Leo. “But it’s always gonna be that one thing you didn’t learn that comes back to screw you.” Comicverse.

In which Mike wants to know why Leo isn't taking advantage of their new freedom to walk above the ground, and Leo is oddly honest. Takes place in Volume 4 of the comics.

After an incident while fighting the Foot, Master Splinter wonders if he has become too old to be a ninja.

Leonardo develops his own meditation technique, but is it too extreme?

Dark Leonardo attempts to piece through what he thinks is his life, or could be if he gains control of it. His brothers aren't so quick to follow. Dark, contains torture.

The ghost in the machine made of flesh. Dark Leonardo

It's Donatello and Leonardo trapped in an elevator at the end of the world. Or maybe just the end of New York; it's hard to tell with the lights out.

Raph wasn't so good at figuring Leo out anymore.

Leo reflects on an action Donnie took. Set during Turtles in Space Pt 1.

In the 5th season, Leonardo is the only one of his brothers to not receive a soul weapon. He spends a lot of time wondering why this is, and finally Raphael has had enough.

Ficlet Seven days until Christmas, Leo starts getting things in order as per routine. The holidays brings out the best, and the busiest, in all of us.

For Raphael, this cycle of misunderstandings and near misses never seems to end... CGI Movieverse, rated T for language.

[Ficlet] A threepart story about time, response, and progression. After the fact, they all react in their own ways. Don seeks to repair. Mikey seeks to create. Raph seeks... tea.

[Drabble] It's the little things that make grief catch up to you, Leo discovers, but it's also the little things that heal it.

[Drabble] It's just another day with Mikey, his action figures, and an epic battle on the field of his bedroom floor. Except... usually Leo isn't there.

Just a sweet little ficlet . . . Leo-centric.

Drabble. Confessing secrets in the night. variation on my other story, To Forget Dreams, no pairing, or OT4 for the so inclined

He remembers when it was as simple as pushing off and flying over a world of color and light. A simple, routine joy that he'd give anything to experience again, so much that rooftops are the lone miracle in his regular life of darkness.

[Drabble, post!Volume Four] Leo stays long after his brothers begin to start the process of leaving. For some reason, he never thought time would be his enemy or only companion.

Leo has no use for stars, but his family does. That alone makes them worth consideration. A ficlet about wishes and brothers, the things he'll never let go of.

[Drabble, character death] Donatello considers his brother's newest scar. Leonardo says a lot of things, none of them heard, but all of them taken gratefully.

Migraines SUCK. Sick!Leo, Mikey, schmoop, done for LJ's ff100. Not turtlecest unless you choose to see it as such.

[Drabble, implied Character Death] One morning between Leo and Raph and all the thoughts in Leo's head. Sometimes you find you've more to say than you thought, but it's too late.

[Ficlet implied character deaths] It's many, many years before he comes back home, when there might finally be something to come back home to.

[Ficlet] Winter comes again and they're only getting older. It's the little things, Leo figures, that make the most difference.

Oneshot. Some people accomplish amazing things while under pressure. Others collapse under pressure. I guess that is one thing that separates the great from the average.

After I watched the episode Exodus, I thought, surely Leonardo couldn't have been the only one to come away with issues. Donatello must have had some pretty substantial thoughts of his own regarding the incident! 2003 cartoon.

A good general, like a chess master, thinks several steps ahead of his opponent. Or, while he's busy escaping, Leo has a brief encounter with Bishop in a hallway. 2003 cartoon.

OneShot. Two brothers are caught in a fight for their lives. But will they survive?

He’s hanging upside down in the middle of the great underdark, weighed down by a half hysterical turtle in the middle of a bunch of pipes and water and rock that are conspiring to kill us both off, and Leo still manages to sound like he Has A Plan.

[Drabble] It's ironic that Raph is the one to head out alone all the time, but it's Leo, following him to protect him, that finds the trouble. One night, one mistake, one possibility, one candle.

Someone's tooth is pulled. While the lair is out of anesthetics. Otherwise, a normal afternoon.

Always put the customer on hold. Right off the bat. Takes some of the fight out of them, you know? Shows 'em who's boss! A 2007 CGI Movieverse oneshot from Leonardo's POV exploring the theme of 'support'. Heavy on character study and brotherly interaction

Leo dreams of monsters at night. But unlike in horror films, his monsters are all too real. Drabbleish, set in the 2003 cartoon universe.

Don remembers the past and is able to make sense of the present. Some people don't change. Leo's one of them. Drabble.

It starts on a night in the rain, with saving Mikey. Soon the nightmares plague more than Leo's sleep, however, and he's forced to play a deadly game with the twisted things identical to his brothers. Getting out of Wonderland's easy. Getting in isn't.

Raphael has a WONDERFUL time, Leonardo is sure this will strike him as funny tomorrow, and Donatello attempts to beat Michelangelo at his own game. Rated for a a bit of language and violence.

[Drabble, death!fic] Sometimes Leo still dreams about Donny in the lake. Sometimes he even wants to.

Misadventures in Maliciously Misattributed Medication' On a routine training mission, Leonardo finds himself on the wrong end of yet another dart, and hijinks ensue. Also, Raphael is a jerk. Bad feng shui and spices enclosed. Concrit well received.

If it's not the last temptation of Leonardo, it could very well be the shortest. Based on the episode, Timing is Everything.

Very short fic. Leo is faced with a choice. Which of his brothers does he leave in enemy hands? Challenge fic.

Once a brother, always a brother, even in the wee hours of the morning. Pure fluff.

They were trying to help, to have everything ready for Don. Shame they missed a trick. Fic challenge A serious tale with a drunk Leonardo.

A challenge ficlet from Stealthy Stories. Raph not at all involved!

What makes an experience so dramatic? Is it truly the experience or the sounds that accompany it? A scene within in a scene. One turtle's perspective on his experience during Exodus.

Mikey's first experience with kata doesn't go so well for him.

100 word drabble in which Don makes a shocking discovery...

Don finds something he truly enjoys...only to have it end in tragedy.

An old enemy returns, threatening both Leonardo's family and friends, but also his recovery. COMPLETE

Donny pays the price for Mikey's late-night craving.

Leo and Donny are on a dangerous late night mission. Will they make it out in one piece?

Leonardo returns battered physically and mentally from a bad place.
