I warned you guys that this update was going to take a bit longer, but thank you so much for waiting. I hope it wasn't too long.

I left you with a cliffhanger, so here's the showdown you've been waiting for. But this big battle is only the start, of something worse yet to come.

Angel looked over her friend Casey, who was laying down on the floor. She had to depend only on the dim lights that made their away through the boarded windows. They had run for cover in one of the many small building. Raphael had quickly locked the door before anyone noticed their hiding place. He helped Angel remove Casey's bag, which was now empty because of his fight with Hun. Raphael removed the mask Casey had given him. In the dim light, he could see some blood on it. He wondered if it was his or Casey's. Raphael gently shook Angel's shoulder to get her attention.

"We should move Case from the light, the Purple Dragons and those other guys might spot him," he whispered to her.

He helped her push his body into the darkness. They grew concerned when Casey made no sound of protest. He was unconscious.

"Damn it Case," he said under his breathe.

He was worried Hun did more than give Casey a bump on the head. He was either exhausted and resting, or slipping into a comma. The same thoughts were running through Angel's mind.

"Your brother," she said in a whisper. "You really think he could help?"

"If Casey weren't out cold we could've fought our way out ourselves… I hate to say it but, Leo's the best fighter I know, and we need his help."

"Aww Raph, that's the sweetest thing I've heard you say."

Both Angel and Raphael jumped at the other voice. They stopped themselves from screaming and revealing their location. The voice snickered at their reactions.

Angel was calming down from the shock, she didn't hear him enter the building, nor did she feel his presence before he spoke. How did he do that? She wondered.

"Leo, damn, how long have you been standin' there?" Raphael said.

"Not too long, I saw you when you entered." Leonardo said looking over at Casey as best he could in the darkness. "How bad is he?"

"He's knocked out cold," Raphael said.

"After we get him out, we'll need to get him to a hospital. What about you two?"

"Me and Angel are fine, it's Casey I'm worried about," Raphael said.

Leonardo noticed some of Raphael's bruises, but didn't think now was the time argue with him.

"Okay here's the plan, first we need to get Casey over the fences, without being detected."

"Obviously, but how we goin' to do that with all those ninjas out there?" Raphael said.

"I'll help Angel carry Casey. You'll lead the way and cover us if anyone tries to attack. They don't know I'm here, so we have a small element of surprise. And, you know, just stick to the shadows."

Angel and Leonardo lifted Casey by his shoulders. He made no sound other than his shallow breathing. Leonardo made his way to the door he had entered in. It was in a separate small room with another door leading outside.

"You go ahead and see if anyone's out there," he told Raphael.

He made his way to the door, and he opened it slightly to look through. It led out to an alley way. It was small and narrow, but no sign of anyone. There were garbage cans and a large green garbage container filled with mostly old cardboard boxes. With his hand he signaled to his brother that the coast was clear. Leonardo and Angel moved up to Raphael and out the door. They ran in-between the garbage cans and squatted down. The alley had two openings, one led to the middle of the whole area, which was basically an open field covered in asphalt with weeds growing from the cracks. Beyond that were more buildings. A few Purple Dragons were watching for any signs of movements. The other way led to a maze of alleyways between dozens of buildings, where the Purple Dragons and the other men were. They needed to go through there and make it to the fence. Raphael went ahead of them again, looking for a place for them to take cover. He found one in-between two buildings, and once again gestured to Leonardo and Angel to follow while they carried Casey. They crouched down again when they heard movements. The men were practically standing over them looking for any sudden movements. They held their breath keeping perfectly still. The two men were dressed in black with swords strapped to their backs. Leonardo noticed that they both had kunai strapped to their belts. They searched, but found nothing and left. Leonardo, Angel, and Raphael stood still for a moment, and sighed in relief once they they were gone. They continued on their way, but just as Raphael took one step, he heard his brother shout.

"Look out!" Leonardo pushed his brother down as a throwing star flew past him, hitting the ground, and digging into it about an inch. Raphael looked at the weapon that had missed him; there was a tint of blood on it. He looked up at Leonardo, the right sleeve of his shirt had ripped, and the weapon had cut across his flesh. Leonardo winced at the pain, but than turned his head to the direction of his attacker. To Raphael's surprise he was looking at the rooftop of a three-story building. The attacker jumped to a fire escape and was making his way down. Leonardo got off Raphael, and told him to get Casey out as quickly was he could.

"You're going to take him on by yourself? You just got hit!" Raphael said.

"It's only a flesh wound, and who knows he might inform those other guys where we are. So I'll hold him off and you get Casey out," He said quickly.

"Fine, but if you're not out in ten, I'm coming back for ya," he said as he moved to Angel to help her carry Casey. They left quickly and tried to find their way to the fence.

By now, the masked man was standing face to face with Leonardo. He tried to move past him to catch Casey, but Leonardo quickly blocked his path. The man attacked him by aiming a punch to his head but Leonardo blocked and retaliated. Leonardo punched, but the man dodged and attacked him again. Leonardo did the same. The man then kicked Leonardo with enough force to knock him down, but it wasn't enough to stop him. Leonardo reached up pulling him down with him. They began to wrestle on the ground, each attacking, but neither getting the upper hand. The masked man finally pushed himself away from Leonardo, and made it to his feet. Leonardo did the same. They were both breathing heavily. Leonardo could feel a trail of blood slowly moving down his arm. He resisted the impulse to look at it, but instead kept his gaze to the attacker. The ninja drew out his sword, Leonardo wasn't afraid, instead he readied himself for the attack.

The masked man lifted his sword and intended to cut down Leonardo, but he dodged, and the man moved his sword to cut him from the side. Leonardo dodged again. His attacker became angry and swung his sword right and left as Leonardo kept successfully dodging his attacks. Leonardo could sense the other's frustration. He backed up in front of the metal trashcans as his attacker jabbed the sword towards him. For an instant, the sword was jammed inside the metal can. Leonardo instantly took hold of the handle and kicked his attacker, forcing him to let go of the weapon. Frustrated, the man launched at Leonardo to retrieve his weapon, but instead Leonardo used the handle to strike him on the head, knocking him unconscious.

Leonardo was breathing heavily. He dropped the sword and clutched his bleeding arm. He noticed the man's chest rise and fall. He picked up the sword again and walked up to him. He removed his belt with the throwing stars. If he should wake up, at least he won't have a weapon to fight with, he thought.

Leonardo sloppily tied the belt around his waist, and continued in the direction Angel and Raphael were headed. He didn't notice the five others in black watching him.

Four of them attacked from behind with their throwing stars. The weapons glimmered in the moonlight catching his attention. He rolled out of the way, still being carful of the sword in his hands. The weapons missed, and like before dug into the earth. Leonardo didn't bother to look up, but instead changed directions to lead them away from his brother. He tried to run, but they soon caught up to him. He held the sword firmly as he stepped into a fighting position. They had surrounded him, and Leonardo slowly turned maintaining his position. All four attacked at once, and Leonardo managed to dodge and block them. They shifted their attacks and he shifted his defenses. He didn't know at the moment how he managed to do this, but he held them off. Instinct and experience were coming together. He somehow knocked one down, and gained the upper hand against the other three, even with their weapons drawn. Then they suddenly stopped, and backed away.

Leonardo didn't know what to make of it, than he saw someone else emerge from the shadows. It was another person dressed in black, but her armor was different. The handles of her swords were red, and she wore a protective vest, and armor over her shoulder. Her gloves were spiked, and she wore a metal helmet. Leonardo wondered if it was the leader of the ninja. His suspicions were confirmed when he noticed the others bow down to her. As she approached him, he had no idea that underneath the mask was the same women he had met earlier. The same one he had admired during training, the ninja leader was Kari.

With her hand, Kari silently ordered the others to leave and continue looking for the others. Leonardo caught on, and attempted to stop them, but her sword was quickly at his throat. He swallowed nervously at her sudden movement. He understood her warning and backed away. He looked into her eyes, the only part of her face that was visible, and he knew she wasn't going to back down. Their battle began, both swung their swords. The metal clashed, and they kept attacking. Try as she might, her sword never reached Leonardo's skin. Instead there was a constant sound of metal meeting metal. Never in her life has she met anyone who could stand up to her. No one has ever kept up with her as much as Leonardo. However, what confused her about the battle was his strategy. Even when she watched him fight the other ninja, she noticed he never made a move to fatally harm his opponents. Even when they mean to take his life, she never saw him make one move to kill.

The fool. Kari thought, In battle, the only life that matters is your own!

She struck the handle of his sword, causing him to let go before he injured himself. He wasn't struck, but was out of a defensive weapon. She moved quickly and twisted his injured arm behind his back, causing him to yell out in pain. With her other hand, she dug into the wound making it larger and deeper. He cried out again, the blood was now flowing faster from his arm. She then pushed him to the ground. He struggled, to get on his feet. The pain was overwhelming him. Then, once again, she lifted her sword and let the cold steal touch the flesh of his neck.

She smiled knowing she had won.

"Great, where'd he go?" Michelangelo said.

They had followed Leonardo closely, but soon lost him when he turned a corner. They had been searching for ten minutes, and Michelangelo's patience was wearing thin. Michelangelo then felt his brother pull him down by his shirt.

" Ow! What th-" Donatello muffled his little brother by putting his hands over his mouth.

"Shh," he whispered. "I hear someone coming."

They looked over the pile of cardboard boxes they were hiding behind. Indeed it was one of the Purple Dragons running through. He soon disappeared as he turned the corner. They stood still as they heard yet another person passing by. Michelangelo peeked over the trashcans.

"Don, you're not going to believe this." He pulled his brother up with him so he could see.

It was Raphael carrying an unconscious Casey, there was another girl helping him whom they had seen only a few times at school.

"Raphey!" Michelangelo called out to him.

Raphael stopped abruptly in disbelief. He saw his two brothers emerge from behind the pile of boxes. Donatello's gaze fell to Casey.

"Wow." Michelangelo said.

"What the hell are you goes doing here?" Raphael said.

"We followed Leo here." Donatello said.

"He told you guys- ah never mind, just help me get him over that gate," he said.

They continued on their way, until they finally made to a small alleyway, which lead to the fence. Luckily none of the Purple Dragons had spotted them.

"Damn, how we gonna get him over?" Raphael said.

Michelangelo inspected the fence. He walked up to it and pulled up a small portion of it. It was loose enough to make a small exist.

"Here, you go first and then pull Casey through the other side," he told Raphael.

Michelangelo pulled part of the fence up to leave enough room for Casey and Raphael. He crawled under and than pulled Casey with him. Angel followed afterwards. Once they made it through, Michelangelo let the fence spring back into place. Raphael turned to Angel.

"Angel you gotta make sure you get him out of here. I'll help you find a safe place and call an ambulance. Go with him when they get here. I'll be here waiting for Leo."

"What if you don't find him? I'm going back for you if-"

Raphael cut her off. "No, you come back this whole thing's pointless. Get Casey help and leave the rest to us."

She nodded, after all Casey's safety was primary. Raphael helped her carry him once more and turned to his brothers.

"You two knuckleheads better stay here and wait for Leo. Stay out of sight."

"Why what happened to Leo?" Donatello asked.

"He stayed behind, fighting off someone to let us escape," he told him as he walked off with Angel. Once they were far from the Purple Dragon's head quarters, which was a near by neighborhood, they called an ambulance. By this time Raphael had removed his hockey mask and hid it in his jacket. The Ambulance took another ten minutes to arrive and Angel accompanied Casey. Raphael watched as the ambulance left, a few people watched from there bedroom windows. He then headed back to his brothers.

Meanwhile Donatello and Michelangelo were waiting for Raphael's return.

"What the hell is going on here?" Michelangelo said.

"I don't know, but Casey and Raph looked terrible. I wonder what Leonardo's doing."

Just then they heard the sound of metal clashing. Then they heard a yell. They turned to face each other, and they had the same expression of shock and worry. They recognized the voice, but have never heard him cry out like that.

" That was…" Donatello couldn't finish.

" We're going after him," Michelangelo said.

They followed the source of the sound. Not to far from where they were they found their brother on the ground. There was another ninja standing before him with her sword drawn.

Donatello quickly scanned for any weapon he could use, and grabbed a trashcan lid and threw it full force at the Kari. She took notice and switched her attack, striking it. Her blade cut threw it and the two pieces fell beside her. Leonardo, holding his arms, struggled to his feet, and stumbled towards his brothers. He picked up the sword and was once again in fighting position, despite his injury. His arm was shaking, but he was determined to hold his own.

Michelangelo and Donatello had the same determined look in their eyes. Whoever these people were, they weren't going to get away with what they were doing. Soon the three brothers surrounded her, but her attention was focused on Leonardo.

They are without weapon, they cannot hurt me so easily. But he is weak and fearful.

She moved to attack Leonardo, but as he blocked, the other brothers attacked her. She was not expecting them to so readily attack her unarmed. She pushed them back, but was distracted when Leonardo used the same move she did earlier to make her drop the sword. She let go of it and growled at her own miscalculation. Leonardo quickly took hold of the sword and was now fully armed. She broke away from their circle and stared the three of them down. Her eye's narrowed as she calculated her situation. No weapon, three against one. However, Leonardo was injured and she was ordered to capture them. But the masked vigilante was not with them. She had let him escape.

Leonardo was tense, he was hoping that they didn't follow him, but was thankful that they had saved his life. At this moment, even though they were staring down the enemy, getting his brothers away from this place was his main concern. He knew she was playing for keeps, and he didn't want to end up with a dead body, not his brothers' and not anyone else's.

Leonardo tried to steady his breathing, trying not to let his brothers or the ninja know how much pain he was in. Just then, standing behind Kari, Leonardo spotted Raphael hiding in the shadows. He held back a grin. Now the ninja had another disadvantage she didn't know of.

Raphael and Leonardo, at the same time, moved towards her to attack. To their surprise, Kari wasn't caught off guard this time. She had sensed his presence and quickly took hold of Leonardo's arms, forcing his swords to aim at his brothers. Raphael instinctively shifted his movements and nearly stumbled to the ground. Once again, Leonardo was at the hands of his attacker. She had hold of both his arms at the wrist. They were face to face. She had a strong grip, and she could feel his injured arm shaking. Despite his efforts he dropped his weapons. The blood lost was now making him feel dizzy. Leonardo tried to move away from her, but felt a powerful blow to his stomach and was on the ground. She had kneed him when he tried to move. He got up quickly, but the sudden movement made him dizzy. Seeing his unsteady movements, Kari pushed him down again and went after the weapons. Raphael let his brother fall in order to stop Kari. Michelangelo and Donatello rushed to their fallen brother.

By the time they got him to his feet, Raphael had only managed to obtain one weapon. Without a second to spare, Raphael attacked her. She instantly blocked with her sword. He yelled out, using all his strength to push her down, but she resisted. Raphael attacked again, and was becoming frustrated. She knew this, and used it to her advantage. She continued to frustrate him by blocking his attacks effortlessly. She then forced him back when she nearly cut threw his stomach. Raphael could feel the power of her cold blade as it almost met his skin. He stumbled back a few feet, losing his balance. Kari then grabbed a throwing star from her belt. She jumped back to have enough distance to throw the weapon. Enraged, Raphael didn't notice her quick movements, and charged at her with the sword.

Leonardo shouted from behind him, Raphael didn't notice she had thrown her weapon. Once again, Donatello quickly grabbed a trashcan lid and ran in front of Raphael blocking the weapon. Raphael froze to keep from striking his brother. He had moved so quickly in front of Raphael that he was panting because of the effort. The weapon had nearly made it all the way through the metal. Kari tried again, but this time Raphael had grabbed his brother to dodge the attack. Raphael ripped the weapon from the lid and threw it back at Kari. It nearly struck her face, but she twisted her body to avoid it. Her efforts caused her to turn away from her opponents for only an instant, but it was enough for them to escape her sight. Kari quickly called the other ninja and ordered them to search for them.

The four brothers took the opportunity to slip into the darkness and find their way out. With any luck, they won't run into trouble.

A/N

This was by far the longest chapter I have as of yet.

I guess your wondering why I respond to reviews and comments like this. I don't always have time to respond to everyone individually by clicking on every name. Yeah it sounds weird but with slow internet I find it better to do it this way. Hey, it works for me =/ but after the next one I'll try doing individual responses if you prefer that instead.

Replies starting from chapter 3:

"Alesia", Thank you and everyone else for the encouraging words. Even though I'm doing this for fun it feels good to know that someone out there "Looooooooooves" my story. Thank you for the kind words!

Second daughter of Eve, thank you for liking this story, and yes I know there are a lot of mistakes, but being the sole writer and editor I miss them sometimes. Sometimes I browse over the chapters I already posted and cringe when I see a misplaced "to" for "too" and a "there" for "their" or other mistakes like that, but I try my best to fix them. Still despite all that, I appreciate the fact that you still like the story and are willing to point out some mistakes. I'll do my best to catch the mistakes in my drafts. Thanks for reading! =)

Magiccatprinces (for chapter 3&4),Thanks for the compliment I'm glad you liked it so far! And yeah, Raphael and Angel take down Hun and the guys kick some serious ninja tale! Don't we all wish we could be like the turtles and fight the Purple Dragons? XD

NickJ1Fan,Thanks for commenting. Leo did at last show up, but things didn't go so smoothly. I hope you liked this last chapter even if it was a little late.

Party-Shoes16, Thanks for reading and leaving a comment, even if you prefer the turtles stay turtles. The story does have elements of the show, but it will also develop in it's own universe. All in all it's just a fun experiment. And in AU stories it's fun to create almost anything.

Poisoned Dark Angel, Sorry for the evil cliffhanger XD . I hope this chapter didn't disappoint you. It's really long compared to the others. I'm starting to love all your little insights. I had other Tmnt characters throughout the story, (characters that I love) but cut them out, because, like you said, they felt more like plug-ins and didn't contribute to the story. Thanks for reading =)

I think that's all of them.

Once again thank you for reading and as always review please!
