(BEING REWRITTEN: BROTHERS SURVIVAL) The turtles are captured by shredder and Leo will do anything he can to keep his brothers safe...

The turtles are forced to leave their lair as a winter storm threatens to trap them underground, and Leo picks the worst time to be sick. Can they survive the cold while being separated? How bad is Leo's fever going to get - and is it only a fever?

All his life, Leonardo's been moved around, and forced to take care of his little brother as his parents paid attention to their jobs instead. When they move to New York, Leonardo meets some new people that change his life, for better or for worse...he's still not sure. He's betting on for the better though. Human AU, probably not quite what you're expecting.

After Leo makes a deal with the Shredder to save his family his brothers decided its time to bring their brother home. Once he is found they are shocked by the amount of trauma he had suffered at the hands of the Shredder. Will the three brothers be able to heal their oldest sibling, or is he broken for good? Chapters are now being updated but the going is slow so bear with me.

Based on the 2012 series. Alternate ending to "Showdown Part 2" and takes place straight after the Krang ship (Technodrome) sinks. However, when the ship went down into the watery depths, what if Leo hadn't escaped in time? (Rated T and small spoilers for season one's finale). Hurt, angst, action, brotherly moments.

When Leo is captured by the Shredder, something is done to him. Something that cannot easily erased or fixed. Lost, alone and broken, it is up to Leo's remaining brothers to repare the damage done to their oldest sibling... But is he too far gone?

After rescuing April from the technodrome and escaping, Raph and his brother's watch as the technodrome falls into the water with Leo still inside. Two years later though the turtles are in for a shocking surprise. OCs. Rated T just to be safe. Disclaimer: I do not own any of the characters or the original story line of TMNT.

Everyone has a dark side, whether they know it or not. It can destroy a person, and that's what's happening to Leo. If his family doesn't figure out why Leo's acting different and help him overcome the darkness within him, Leo's good side will be lost forever. (2k12 verse)

You've seen the movie Frozn, but take from a different angle as three mutant brothers try and save their home and their eldest brother from the curse that has fallen upon them.

What if Hamato Yoshi didn't leave Japan right away, and found four baby turtles abandoned in the forest? What if one of the four mutated brothers had lost their way and run into another larger mutant? This is the story of what if a certain tiger mutant had raised his own turtle son, and how that turtle had to choose between two families. (I OWN NOTHING, AU FIC, R&R and Enjoy!)

When the turtles ask Donnie to test their blood to see if they are really related he finds something shocking about one of his 'brothers'. Master Splinters sends his child away so they can come to terms with this alone. But what happens when their missing fourth doesn't come back? And what's with Donnie and Raph?(Ratings Might Change) 2k7 AU.

Summary: Alternate ending to "Vengeance is mine". What would've happened if Karai and Leo fell into the mutagen tank, but instead of snake mutants, they become wolves with no memory of their past lives? The only thing they remember is a close bond that holds them together, and a pure hatred for the Shredder. Life begins a new as the newborn wolves must learn how to survive NYC

(Originally by Mew2fem) Leo leaves from the lair mentally hurt and is hit by a dart and shrunken into a new mutation. Leo is mentally hurt more then ever and Raph doesn't help with losing his temper. Can Raph restore Leo's broken heart? How low can the Hamato family go before Leo runs from them forever? How can a sweet innocence be so tormenting... (Raph/Leo, AU)

For all Leo has know, his brothers acted weird towards him since age 5. He was different; his eyes changes color depending on his mode, he got sick a lot, and he sees these three figures in his nightmares. Now, age 15, Leo is aloud on the surface and hunts these figures down for his family. But he never expected his worst nightmare to come to him in these ways and forms...(2k12 AU)

One of two intertwining stories, the other story can be found in the Batman the Animated Series section, two sisters argue over which show is better BTAS or TMNT, a spell sends transforms both of Girls into Mutant Animals and sends each sister to the Other's Favorite Show, Chapter 23 Emerald and Leo have a long talk

When does it become too much? How much can one person handle before they break? Is it possible to fix the broken? [Human AU/Past Abuse/Past Neglect/Mentions of Rape and Kidnapping]

Leo has denied being sick, and it has finally caught up to him in a less than dignified manner.

AU. A mutant turtle named Madison Kame kidnaps an infant mutant turtle from a New York hospital and raises the child as is he was her own son (Based On True Events)...

This is a Shredder and Leonardo story

Each turtle has their own fears and each comforts a certain brother. In this story see how the turtles face their fears in the night and how they need their brothers more than they will ever realise! Rated T for safety.

"Raph!" Leo shoved his brother aside and collapsed when the shot connected with his side. There was a silent BOOM, a flash of purple light, excruciating pain for two heart-stopping seconds, and then his vision went black.

Leo and Raph are captured by shredder and tortured slowly. When they get rescued Leo started rembering things from their capture. Will Leo be ok? Will his brothers help him through it or will he suffer?

AU. Raphael, Donatello and Michelangelo encounter a wild mutant turtle in a Kraang base, who turns out to be an infant that Master Splinter lost 15 years ago and raised by wild mutants. Now they all have to help bring their long lost brother back to them once again...

Sorry im terrible with summaries. This story takes place in medival times were its frozen and the turtles are humans and are princes who are ninjas and Leo has a bad condition. Story is better than summery. please read

A decade ago, Leo always wondered why one of the sheep from his family's farm went missing each month. When he grew up, it increased to once a week. He then wondered, is there anything that could get any worse? He should have never asked. This story is an AU. There will be mature content and T-cest in the later chapters. Don't say I didn't warn you. Ratings may change.

Kidnapped by kraang, stripped of his shell and now he's guiding himself through the treacherous New York under a secret identity, Leo now has to fend off shredder, his brothers and the kraang all while getting sweet, sweet revenge.

Lulled into a false sense of security after the Mushroom Man is defeated, everyone assumes everything is fine. Yet Leo still seems to be troubled by vivid nightmares and when those nightmares turn into hallucinations, his brothers and father are there to help pick up the pieces.

A week ago Leonardo was snatched by the Kraang and taken away to who knows where, yet after seven days of searching, April senses the leader's in extreme pain and where he is. Can the turtles find Leo and if they do- will he ever be the same again? Anything more will ruin it. READ AND REVIEW. WARNING contains torture, pain, suffering and maybe more!

what happens when leo gets separated from his brothers and meets an unusual somebody who will eventually help him become the great assassin. sorry I suck at summaries first story plz don't be to mean

This story was given to me from the author Trinityzero. That author decided they weren't going to continue the story Secrets, so they gave it to me. I am Hamato Leonardo. Well, that's what they call me. To my 'brothers' I'm the honest one. Not true. Every word out of my mouth has been a lie. I've been hiding my dark side for over ten years now. But now it's ready to show.

You never realize how much you actually need your brother until he's taken from you.

I am Hamato Leonardo. Well, that's what they call me. To my 'brothers' I'm the honest one. Not true. Every word out of my mouth has been a lie. I understand that everyone has secrets. But mine's dangerous. If anyone found out that's a risk that my father might find out. I've spend over ten years trying to hide from him. Hiding my dark side, that's what I'm good at.

After 2 years of training in Japan...Something seems to have gone wrong, Ancient One send for the family's aid as one of their own is in grave danger...But what can they do against a maniac who can turn his opponents to stone statues? Warning: grab your plushies after chapter 9!

"The Invasion" reimagined. What if Leo was taken captive by the Foot instead of being thrown back to his brothers? Tiger Claw has the task of watching over the turtle. Inspired by RingingT's comic on deviantart, and a personal experiment on getting into Tiger Claw's head.

"It looks just like a scene of childhood. They spent a night on the bed curled up on each other. Mikey on one side trying hard to cuddle both of his brothers tight, Donnie on the other side dozing peacefully, and Raph in the middle hugging them both like his little kids. All that's missing is an older brother lying beside Mikey, and an elderly rat silently watching them sleep."

Leonardo is too serious all the time and trains his brothers to the point they get tired of it. One day his brothers, fed up with his seriousness, decide to play a prank on him by hiding in the sewers in a harmless game. Because of a enemy everything goes haywire and they see a different side of Fearless Leo that surprises them. Warning: Slightly gore imagery and overprotectivenes

The mirror isn't the only portal, and the world of Equestria High isn't the only other dimension. A lake in Central Park, NYC, is a gateway to Ponyville. One turtle will fall through the portal and come out a pony.

Leonardo is raised by shredder.Karai doesn't want to loose him,but it doesn't look like he is going anywhere anytime is is my first fanfic so enjoy.I own nothing.Rated t just in plete

Leo gets sick with a weird disease. That's pretty much the whole plot. Story is hopefully better than description. 2012 verse. Set before the invasion.

AU Leo used to happy, living in a wonderful moment. But then that moment ended. Now, Leo is a meek, skittish turtle cloaked in a mysterious sadness. After a strange reaction to a song, his brothers finally decide it's time to investigate again. Leo has a secret he's kept for years, hidden behind his walls. Now, his walls are about to come crashing down, and his secret is coming out

An alternative version of the bathtub scene from the season 3 premiere.

Written for the TMNT's 30th Anniversary. The Shredder has been having visions of alternate versions of himself being continuously defeated by different versions of his greatest enemies the turtles. Will they be saved from the wrath of his vengeance? Or will they be consumed by it? Chapter 9 up :) Rated for turtle torture (may go up though)

2k12 'verse. Set right after Slash and Destroy. Slash gives Raph the gift he's always wanted. To tell Leo just what he thinks of him. Rated M for swearing, torture and sexual molestation.

Donatello finds a rather shocking secret about the team's fearless leader and madness ensues as Leo has more secrets one could even imagine. Note: Believe it or not 1st Chapter can be read as a one-shot.

When Casey's in a bind, Leo's the one he turns to for help...much to Leo's dismay. "So whaddaya say, Leo? Can you help me?" "Uh...Casey, I really don't think I'm the right person to ask. Why don't you ask Raph?" "Come on, you know I can't ask HIM. I'd never hear the end of it."

Well, Donnie did it this time. The chemicals in his lab exploded, and caused Leo to become a human! So now he has to deal with a whole new body, going to school, fighting the bad guys, and homework. And the new girl who isn't so new is going to only make life harder for our leader in blue.

Sticks and Stones may break ones bones, but words will always hurt you. Setting in 2007 TMNT movie.

Slight AU based on the season finale, "Vengeance is mine". In which, Leo did not duck. Discontinued until further notice.

Title says it all. The brothers know they can always lean on one another.

Inspired by a video on youtube: The turtles have fought with the foot clan, how well did Leo go?

A disastrous fight. Pain and suffering. How will the turtles make it through this one? Read to find out. I am considering , though as of now the story is completed, adding to this Leo's POV(kinda POV) and maybe some future chapters to go along with it. I all depends on how many reviews I get. I do not own TMNT.

When the turtles accidently switch the coordinates for the Kranng's Dimensional Portal, they wind up in alternate future dimension...and meet their selves? What kinda crazy adventure is in stored for the turtles now? Find out in TMNT: Double Fast Forward. (2k12 meet 2k3) Chap. 3 is Up!

Story Inspired by a tale begun by tmntlover 2013 who has allowed me to write a version of her idea. Leo has a secret that he has kept to protect his brothers for years. Why is this happening? What has he ever done to deserve this?

Mikey's prank for Raph goes wrong when Leo eats the muffin with a strange chemical inside it. Now Leo has to deal with some terrifying stuff in his dreams until or if he wakes up.

Leo is captured by Karai and he finds out that the Shredder's little girl is deliciously evil and wickedly delicious.

Being the oldest, he felt responsible for everything. His brothers came first every time, even when it cost him everything—including himself. Leocentric one-shot.

After Leo is captured by the foot, will the Shredder kill him? Torture him into giving him information? No slash or anything. I don't own anything. Rated T only for blood... and possible death

Enough is enough. Leonardo is sick and tired of his brother's attitude and decides to try a new tactic in dealing with his brother's anger and quite possible hatred for him. Will Leonardo's plan solve things with Raphael once and for all, or will it tear the two brothers and their entire family apart for good? Rated T for angst, tension, action, violence all that good stuff. Enjoy

Leo has a fight with Raph, goes out for some air, and then is captured by the Foot. What will be the outcome? 2k3 verse

"Pulled from the future after the last of their interactions with their counterparts by Renet, the Dark Turtles find themselves playing a crucial role in bettering the time-stream. They've been given the task of healing a depressed Leonardo, but they end up changing their own lives for the better as well." An AU season 4 rewrite like no other.

Warning: contains gender-bend! While testing his family's blood samples, Donnie makes a discovery regarding one of his siblings. How will the Hamato clan deal with this sudden change?

When Leo set out to find Raph, he gets captured by the foot, who then decide that instead of immediatly killing him, to use him as a lab rat to test cures to the mutation. But will they find a "cure", or something entirely different?

Au. What if Leonardo had been raised by the shredder? How would everything change? Nominated for Best AU in the 2010&2011 TMNT Fanfiction Competition.

AU Human turtles. Leo seems to have caught Mikey's cold, but never fear! Donnie, Raph, and Mikey are here to help their sick brother, though he might be better off on his own... Humorous antics, odd situations, and fluff abound!

The turtle brothers deal with the tragedy of their father's death and their eldest brother comiting suicide. Suddenly Leo appears to Don, but only Don can see him. Leo's soul is stuck in the middle between life and death. Don will have to find his body and fix things before Leo disapears forever. ON HIATUS

Sanji is angered by Zoro's lack chivalry. He plays a prank that goes wrong. Zoro and Luffy share a secret relationship. ZoLu Lemon smoothy...

Something had happened to Leo while he was in Central America and he's keeping it a secret from his family. Why, you may ask? Maybe because the truth is a bit too hard to believe...

Mikey pulls the ultimate prank on Leo and gets video evidence of it! Not really a songfic, but has a few lines in it.

Broken, battered, but he's not giving up...captured Leo struggles to survive the tortures he is submitted to...but when he escapes will his family accept...the surprise he brings along?

All I can say is someone dies, but it's not who you think it is. For now I can conclude that I'm on the turtle's top ten wanted list. At least Raph's and Leo's.

An evil parasite has been feeding on mankind for thousands of years. Every twenty five years it must find a host and a sacrifice. It has found what it needs under the streets of New York.

It's amazing how words so small can make the biggest impact on our lives.

When one of the turtles mutates differently will he be able to survive? When they will already have a hard life what will it take for his brother's to accept him? AU.

They lost the leader, the big brother. But some how, fate desides to play a little game called "Death's Hand." How is it played? With a bunch of twisted fates and agreements beyond human comprehension. Luckily the main pieces aren't human. Mass rewrite of all writings has begun. There is a chance that completed stories will not be touched in this mass rewrite.

Leo's secret is out, but when it's pulled from him, he's left with some surprising effects. What happened to Leo's soul? TMNT is not mine: Read and critique, please! Leo/Mikey fluff. SERIES DISCONTINUED

Leonardo's family insists he harbors a secret fear of snakes.

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.

Another oneshot. My first attempt to be lighthearted. Raph, Mikey, Don, and Leo catch up on events that happened in the Battle Nexus.

Leo suffers a breakdown after spending eight months in enemy hands. MAJOR ANGST! If you don't like character suffering please don't read it and then flame me afterwards. Thank you : Complete!

Raph isn't feeling well and takes it out on Leo (a little too much)COMPLETE

Leonardo witnessed the death of a young TMNT girl he returns home and takes out something that will change his life forever
