A/N: This one was a little harder to piece together. Anyways, I hope you guys like it!

Disclaimer: I do not own the TMNT.

A small green figure stood at the end of a dark sewer tunnel, just outside the shadows. He wore a blue mask that covered the upper half of his head. His soft gray eyes stared cautiously into the shadows. He held a rotten apple in both of his hands. The apple was dark and wizened. Something had bitten it at one point, revealing its rotten blackish-yellow flesh. A twisted stem poked out the top of it, accompanied by black and shriveled leaves. A steady dripping sound from water running down a rusty pipe was the only sound that could be heard. The young turtle was only about three feet tall and no more than four years old.

"Where were you?" A young voice whispered from the shadows. The voice was raspy, as it had not spoken in a long time.

"I was looking for food. I'm sorry, this is all I found." Leo said, holding the apple out to the shadows. "It's okay. I know that it's hard down here. You don't have to do this for me. Just worry about yourself." The voice replied, the speaker was all but invisible in the shadows. Leo shook his head, a worried and sad expression was fixed upon his young features.

"No. I won't turn my shell on you. I'll keep you safe."

There was a shifting sound from the darkness and the apple was snatched from Leo's hands with a swift motion. There was a silent pause before a loud crunch echoed in the tunnel as the shadowy figure bit into the apple. Leo sat down cross legged, just at the edge of the darkness. "Why don't you ever show yourself in the light?" He asked, his eyes scanning the shadows for the person hiding in them. "It's for the same reason that I can't get food for myself. I just can't. You're… You're," The voice paused, searching for a word. "You're the right one. I'm not. I can't… I can't do what you can… Leo." The voice continued.

Leo's eyes widened.

"That's what they call you right? Those other voices? I can hear the echoes here. I didn't know that's what a name was." The voice said before taking another bite of the rotten apple.

"Leo, what's my name?" It asked.

Leo bit his lip. "I don't know. I need to go look for more food. I'll think of a name for you. I promise." He said, standing up. He turned and his bare feet padded against the cold stone as he walked down the dark tunnel. The sound of a crunching apple echoed behind him.

"Hurry back. It gets lonely here in the dark."

-.-.-.-.-.-

Leonardo leaned back under a heavy punch from a large scaly fist wrapped with tape. His mask tails fluttered with the swift move. He straightened as the fist drew back. He raised his own taped fists; his steely gray gaze regarded his opponent with cold calculation. Sweat beaded his emerald green skin and his breath came out in swift huffs. He leaned to the right, ducking under a left cross. He moved in, closing the short distance between himself and his larger opponent, keeping underneath the outstretched arm. He only had a split second before the fist drew back. His left elbow impacted a tough stomach with a heavy thump. Leo leapt back, avoiding a tail swipe that would have knocked him flat over. He brought his fists back up and he bounced on the balls of his feet. His gray eyes held a glint of fire as he regarded the large mutant across from him. Leatherhead was in the same stance as Leo, but he was not bouncing. He was a solid wall of scale and muscle. He was sweating though and panting just as much as Leo was. They were both exhausted. Leatherhead's green gaze met Leo's.

"Leonardo, might I propose a break?" LH suggested, keeping his fists up and maintaining his stance. Leo kept his stance as well but nodded once in agreement. Both dropped their hands to their sides and their shoulders sagged. Leo's features broke into a warm smile. Leatherhead regarded his friend with a similar expression. "You have improved greatly, Leonardo. I could hardly keep up most of the time."

Leo walked over to his much larger friend and patted him on the shoulder. "Thanks, LH. You nearly decked me with that last move. I seriously didn't see that coming." He said with chuckle. The tall alligator chuckled and a blush crept into his features. "Thank-you Leonardo," He said.

The abandoned subway terminal was bright and spacious. Statues stood in certain areas and a blue wash of light from the ceiling gave the area a calm feeling. The two walked over to a stone bench, the white Tupperware sat on it. Leo gave Leatherhead a wink and opened it. The warm scent of cookies wafted from the plastic box. Leo took one and munched on it, a sweet taste filled his mouth with a warm sensation. He motioned for Leatherhead to have at the cookies and the larger mutant gingerly took one in his large hand.

"So Leatherhead, what were you doing before I got here?" Leo asked before taking a bite from his cookie. The alligator nodded once and made a waving motion, meaning he wanted Leo to follow him. Leonardo frowned in puzzlement but followed as Leatherhead began walking towards a desk that had been pushed up against a wall. On the desk were several small round metal spheres. Leo glanced at Leatherhead questioningly. The alligator handed one to Leo. The blue masked terrapin studied it curiously. It was small and black, about the size of a lime. A sudden blue glow emanated from the object and a hologram appeared in front of him. It was an image of him and his brothers sitting about a campfire, roasting marshmallows. He glanced at Leatherhead in confusion.

"Random Access Memory Spheres, or RAMS for short. These allow you to review any memory you so please. I found it useful for when I misplace something or when I want to remember my time with the Utroms." Leatherhead explained. Leo nodded once. "How did you come up with the idea to make this?" He asked as another image appeared, this one was of the Ancient One. Leatherhead shrugged. "I just thought it would be an interesting thing to consider. I wasn't even certain that it would work." He said with a chuckle. Leo handed the orb back to Leatherhead who only motioned for Leo to keep it. "I think you should keep it, Leonardo. These items have a mind of their own. I infused them with Utrom technology, you see. They are part organic and part… well inorganic. They bond with one person and keep the bond. It seems to have chosen you." Leatherhead said. Leo glanced at the small object in his hand. Another hologram appeared. Both Leatherhead and Leo glanced at the hologram and both froze. The hologram was dark, but they could make out the image.

Blood. Tears. Darkness. They could see the faint trace of blue from a mask as well as silver-gray eyes. Leo dropped the sphere and the hologram fizzled out of focus. The sphere hit the ground with a metallic clack and the blue glow disappeared. Leo took a step back, a look of horror fixed upon his features. Leatherhead was too shocked to say or do anything. He had never seen so much blood before. He stared at Leo who only soundlessly opened and closed his mouth. The blue masked terrapin turned and fled. Leatherhead watched him leave; he didn't know what to make of what had just happened.

-.-.-.-.-.-

His chest heaved with uneven breaths as his feet slapped against the cement beneath him. The night air bit at his running form with its freezing fangs. The moon glowed silver in the sky, surrounded by stars. Gray bricked walls rose high into the sky around him as he ran down the alley. His blue mask tails fluttered behind him. His mind raced just as much as his body did. Scattered thoughts, questions, and desperation filled his mind. He turned a corner in the alley way and leapt over a scattering of trash that overflowed from a dumpster. The ground was slicked in brown muck, a mix of snow-slush and dirt and trash. He ignored the filth and ran. He slowed to a stop as something in his side flared painfully. He brought his left hand up to the right side of his abdomen. He breathed in painfully. Just a side stitch. He had been breathing in too much, trapping carbon dioxide in his body. He needed to regain his control and calm.

"Back off!"

Leo's head snapped in the direction of the sound, his eyes narrowed. Voices. Getting louder with each second. He could hear approaching footsteps as well as the sound of a blade exiting a scabbard. His hands tightened into fists. This was not the time.

Sure enough several raggedly dressed men turned the corner he had turned only a minute ago. They followed three other men, one bleeding profusely from his arm. Red blood had already soaked his loose sweater. All of the men looked like gang members. Tattoos covered their bodies, they wore oversized jackets and their pants hung past their knees. The group jeered and hooted at the other three men. Leo tensed; he was itching for a reason to strike someone or something. The hologram from the RAMS brought back memories he didn't want to think about. The image could only have been from the accident that nearly tore him apart. He certainly wanted something else to do, to think about. Beating some thugs down would certainly meet that desire.

He began moving towards them. His rationale was powerless against his need. His silvery gray gaze narrowed, his shoulders squared and his he rotated his neck, preparing for a fight. The thugs spotted him quickly as he came into view at a steady walk. The larger group lost interest in the other three men and turned to him.

"Órale, vato, get lost or else!" One of them shouted at him. Leo continued his walk, not pausing, not fazed. The men could not make out his green skin yet, only his dark silhouette. He soon made it into view and laughs broke out. "Oh look, we've got some idiot in a frog suit! Whatcha' gon' do, froggie?" Another sneered. The men began to fan out, surrounding Leo. The terrapin warrior stood still, he gave a quick cursory glance about him. Only seven men. It wasn't even going to be a fight. He remained still, the other men made a few more snide remarks but none moved to attack him.

"You just gonna' talk, or are you gonna' try and hit me?" Leo asked calmly. He wasn't interested in playing games with the thugs. They flinched at his remark and moved forward to strike. One swung a metal pipe at his head. Leo stepped back and grabbed the back of his attacker's wrist. He slapped his free hand at the back of the attacker's elbow. Using the joint lock, Leo hurled the man into a pair of thugs. They tumbled to the ground in a jumble of arms and legs.

Leo dropped into a crouch under a left hook and slammed his elbow into the new attacker's ribs. There was a crack and the thug hit the ground with a cry of pain. Leo rolled to the left, avoiding the swing of a bat. He rose to his feet as the bat-swinger swung wildly. Leo's left arm whipped out, striking the inside of the bat-swinger's bat-arm and effectively halting the attack. Leo moved his right leg behind the bat-swinger and gave the man a hefty uppercut. The man leaned back with the blow, tripping over Leo's leg and hitting the ground on his back. Leo swung back and under a wild punch, coming behind another thug. He struck quickly; delivering a series of swift punches to the thug's left side. The thug slumped to the ground with a groan. Leo turned to regard one thug still standing. The man looked ready to piss himself. He whipped out a knife and held the weapon out at Leo threateningly. The turtle cocked his head and gave the knife a dismal look.

"Really? I took out six guys, some armed, in less than a minute, and you think I'll just suddenly become a coward at the sight of that pocket knife? You've really got to change your mentality." Leo said with obvious annoyance. The man only charged. Leo could at least give him credit for not running away. The blade came to rake across his eyes. Leo leaned back and the blade passed inches away from his bright gray eyes. Leo caught the back of the man's wrist and twisted his arm sharply as he bumped his hip into him. The man twisted and fell ungracefully on the floor on his front. Leo plucked the knife from the man's grip. "Before you hurt yourself swinging this butter knife around," Leo muttered. He traced the blade alongst the man's jaw line. The man stiffened and regarded him with fearful wide eyes.

"Oh. Not quite so confident now, are you? You should have ran. You know what? I'll make a deal with you. If you quit this gang business of yours, I'll let you off with this warning. Now, should you persist, I'll find you and make you wish… Well, let's leave the rest of that to your imagination." Leo threatened calmly. He had no intention of spilling anyone's blood anytime soon. It went against everything his family believed in. It went against everything he believed in. He stiffened. Here he was, trying to forget the accident, yet, he just kept bringing it back up.

CRACK!

Blinding pain erupted from the back of Leo's head as a large solid plank of wood splintered apart upon striking him. Leo fell on top of the thug with a pain induced groan. The thug shoved him off, sending the stunned turtle rolling onto his shell. Leo's vision was filled with stars; he shook his head, trying to clear his vision. He screwed his eyes shut as an echo of pain erupted through his skull. He instinctively rolled to the right. A heavy thud resounded from where he had just been lying. Leo regained his footing and shakily rose. He released a deep breath and opened his silvery-gray gaze. His eyes narrowed at the sight of two thugs standing across from him. The one he had disarmed was now wielding a metal pipe and the other wielded a splintered shard of wood. Leo felt something feral inside of him snarl, like a beast at the end of its chain. Leo rushed forward, unsheathing both katanas. He was done playing games with these foolish humans.

The two men swung their weapons in unison and Leo's katanas swung from the left to meet them. His katanas sheared through both weapons like butter. Leo proceeded to bash the pommels of his weapons into both of the thugs' faces as he passed between them. Crunching sounds erupted as the metal pommels struck soft cartilage and solid bone. The two thugs staggered back, Leo turned on his heels and faced them. They clutched what remained of their bloody and crushed noses. Leo strode towards the one who had struck him with the wooden plank before. He moved differently. All warmth and brightness had faded from his eyes. His mouth was set in a grim line of apathy and his gaze held a certain disgust. Leonardo brought his right hand katana back and swiftly cut through the thug's neck. Blood spurted as the blade severed the man's jugular vein. The quiet crack of the man's neck bone told the other thug that he needed to get away.

The man staggered to his feet and began a mad dash away from the blue masked terrapin. Leo's eyes calmly followed the man's running form. Leo stabbed his left hand katana into the dead man's abdomen and changed his grip on his right hand katana. He brought back his right arm, judging the distance with cold calculation and hurled the weapon. The blue hilted katana sailed through the air accompanied by a whistling.

The man turned his head at the sound. His eyes widened in fear and he uttered a scream. The blade pierced through his forehead with a wet crunch. Leo turned to the other men, who were just stirring. He tore his weapon from the dead body and strode to the prone men. One by one, as Leo passed by them, he slashed through each of their throats before they could fight back. Blood began to pool around Leo in a puddle. His feet were as red as his blade.

The three men who had not engaged in the conflict, one of which wore a blood soaked sweater, watched in silent horror at Leo's methodic slaying of the men. They remained quiet and still, so as not to become victims of Leonardo.

Leo flicked the blood from his katana before sheathing it on his shell. He had seen the other three men, but he would not kill them. Not tonight. Let them feel the fear. Let them fear him. Anyone who struck at him deserved nothing but death. They had attacked him with the intent to kill, why not repay the favor?

He froze suddenly at that thought. He blinked once. Twice. Three times. What the hell did he just think? What the hell did he do? Leo dropped his gaze to the dead bodies of his victims. So much blood. He had seen it before, at his hand as well. His lip quivered and his hands shook. What the fuck had he done? He backed away from the bodies, only to step in more blood. He couldn't take it. He couldn't take it.

Leo ran.

-.-.-.-.-.-

"I didn't think you were going to come back, I was so hungry, Leo." The voice whispered from the dark. It sounded weak, frail, and yet there was a sliver of hope in its voice.

The young Leo stood just outside the shadows. He did not look at the shadows, only offered a piece of moldy bread. The bread was snatched from his hand. There was a munching sound as the shadow began eating the vile scrap. Leo felt bile rise in his throat but he ignored it.

"I have a name for you." He whispered almost inaudibly.

"Really? What is it?"

"Naito."

A/N: Alright! So, any ideas on who or what Naito is? Please tell me everything you think in a review :)
