NOTE: This is my first fanfiction so, i hope you like it. Enjoy! :)

It was a normal night in the sewers. Mikey eating pizza, Donnie and April in the lab, Raph training in the dojo, Splinter meditating and Leo watching TV. Suddenly, Donnie and April run out of the lab, carrying Donnie's laptop.

"Guys! Take a look at this!"

April cried "All of the KRAANG are there! They must be hiding something!"

While watching the surveillance, Mikey says with a confusing look, "Uuummm, There hiding a.. wall?"

"It must be a hidden door." Leo replied.

Raph, taking out his sais, "Then, what are we waiting for? Let's get a move on!"

Everyone headed to the van in a speed.

"Hey! Can i come?"

Donnie replied "Well-"

"NO!" Master Splinter yelled.

"Bye, April!"

The van took off, leaving a disappointed April.

Donnie opens the live video on everyone's screen. In the video, they see lots of KRAANG, holding shotguns, guarding the hidden door.

"What do you think is inside?"

Mikey gasps, and replied, "Maybe there making a cow mutant that will milk the whole city!"

By saying that, Raph slaps Mikey. "You and your big mouth".

Mikey replied, while touching is cheek, "It was only a suggestion!"

Raph glared, "A stupid one!"

"Both of you! Stop it!" Leo cried to the both of them.

"We're here."

In the KRAANG's building, an android stood there, guarding the halls. Suddenly, A green hand covered the android's head and grabbed it to his side. In a second, the 3 turtles came out and sneak through the hallways. After taking down all the android in there way, they finally made it to the hidden door, where hundreds of KRAANGs guarding it.

"There's to many of them! We'll never make it!"

"We need a distraction" Leo replied.

Everyone looked at Mikey.

"Ugh! Fine!" Mikey says while rolling his eyes.

Mikey took off and he face the millions of KRAANGs.

"Yo, butt droids! Come get some!" Mikey waved at them.

"KRRANG adviced KRAANG and adviced KRAANG to take down the turtle."

Few of the KRAANGs followed Mikey into their trap. After awhile, it was time to take down the few that had stayed. Donnie manage to reach the hidden door to hack the code. Unfortunately, there wasn't a code to hack. It just look like a wall!

Leo cried "Anytime, Donnie!"

Donnie replied "I-I can't open it! It's just a dead wall|!"

Raph, slicing an android to 2 pieces, "Well, you better find a way!"

Donnie looked everywhere at the hidden door, looking for a some sort of switch, sadly, he couldn't find any. Leo and Raph have finally finished beating the rest of the KRAANG and joind a confused Donnie.

"I'm sorry, guys but, i don't know how to open it! It's impossible!"

Suddenly, Mikey joind them while out of breath.

"Where are the rest of the KRAANG?"

"Th-They (huff) l-l-ost me. (huff)"

"Ok, guys. Help me find a switch to open this thing!"

Everyone was looking for a switch. Except for Mikey who was catching his breath. A few minutes have passed, and the turtles have give up.

"It's no use! We're never going to get in!"

While his brothers were finding a way in, Mikey leaned to the hidden door. But suddenly, he fell. His brothers turn to see their younger brother gone.

"Mikey?"

The brothers walk to the hidden door, searching for their little brother. Suddenly, Mikey's face came through the hidden door. He was facing Raph, who screamed. Of course, Mikey laughed at this.

"Oh, dude! You should have seen your face!" Mikey laugh.

"Quit it, Mikey!" Raph growled.

Donnie approach Mikey with wide eyes, "Incredible! We can get through the door!"

"Then, let's go!"

3 brothers went through the door and they were shock of what was around them. There were plenty of mutagen around them in big tanks. It was shocking to see.

"Woah." Mikey said looking at a big tank of mutagen.

"I-I've never seen this before! It's incredible" Donnie looking inside the tanks.

Suddenly, they heard electric sounds in the corner of the room. Carefully, they sneak to have a look of what it is. What they saw was 3 androids in a big tank. 1 was facing the tank, 1 was in front of a switch and 1 was next to another android.

"The one known as our prisoner to tell KRAANG, where is the mutagen."

In the tank, there was a long red-headed girl, with a long green sharp-lizard tail, she had medium fin ears, she had long eyelashes and she wore a silver suit and was hand cuffed with big handcuffed that goes to her elbow to her hands. She was closing her eyes like she was sleeping. Suddenly, she slowly open her eyes. She had beautiful pale blue eyes. She glared at the android in front of her. She wasn't moving her lips but, we heard feminine voice in the room.

"Like i would tell you, aliens."

The android looked at her for a moment and turned to the android with the switches and nod. The android nod back and pressed a button. In tank, they started electrifying her. In the room, they heard a painful scream. It was hard to see for the turtles.

"We had to get her out of there. There torturing her!" Raph replied, taking out his sais.

"Ok, on my mark. 1.. 2.. 3..." Leo counted.

"BOOYAKASHA!"

All 3 androids turn to the turtles. The lizard girl looked at them weakly. 3 androids took out their shotguns and battled the turtles. Unfortunately, they lost.

"Donnie, you know the drill"

Donnie nod and ran to the switches to get the girl out. She was just laying there, weak, unconscious. After a few minutes, the windows of the tank finally opened. The turtles ran to the lizard to get her out. Donnie touch her neck to see if she was still alive.

"She will be fine. We need to get her out of here." Donnie says looking at the lizard with pity.

"Don't have to tell me twice." Raph replied while carrying the mutant girl.

They all ran out of the building and head out to the sewers. Once they finally arrived, Donnie took the mutant girl to his lab. April and Splinter had a shocking look in their faces, seeing the badly wounded girl. April ran to Leo, Raph and Mikey for an explanation.

"Who was that?"

"We found her getting tortured by the KRAANG." Leo replied still looking at the door where the mutant girl was in.

"Will she be alright?" April ask with a pity look.

"Donnie said she will be fine." Leo said with a weak smile.

April sigh with relief. Master Splinter walked to them for an explanation as well. They told him what they told April. Suddenly, Splinter entered Donnie's lab where the girl was in. She was lying down on Donnie's lab couch. Donnie manage to tame out her handcuffs. Splinter walk to the unconscious teenager and kneeled. Donnie looked surprised and back up. Splinter closed his eyes and raised his rat arms to the girl. He was saying something but, Donnie couldn't here it. After a few moments, Splinter stood up and look at the teenager. Donnie looked confused and looked at the girl that he and his brothers had rescued. In a second, the girl opened her eyes and gasp for air. Donnie was shock. Her wounds were gone. Splinter had healed her. He never knew his sensei could do that.

"Are you alright, child?" Splinter asked the girl.

The girl looked at him with wide eyes. But suddenly, she calm down. Not the reaction that Donnie was expecting.

She answered "Y-Yes.. Thank you."

She touched her head like she just had a bad headache. She sat on the couch looking around her.

"Wh-Where am i?" she asked.

"Your in our home. Hi! My name is Donatello. But, you can call me Donnie." Donnie smiled.

She smiled back. She tried to stand up but, she quickly fell. Donnie and Splinter help her up. She soon learned her balance and started walking all over the lab. Splinter had left the room to talk to his sons and April with Donnie joining him while the girl stayed.

"So?" Raph asked.

"She is fine. Thanks to master Splinter." Donnie smiled to his sensei.

All of them looked at each other confused. Thinking of what Splinter had done.

"Can we see her?" April asked.

"She needs some rest. We will speak to her in the morning."Splinter replied after taking off.

April have went off home while everyone was back asleep. But, in everyone's mind, there thinking about the girl. Worried looks came to their faces and ask the same question to themselves...

"Who is she?"

The next morning, the turtles were eating breakfast. It was quiet in the kitchen. No one was talking. Splinter broke the silence.

"What is on your minds, my sons?" Splinter questions to all of them.

"It's just that... The girl has been tortured. We don't know how long but, we weren't there to save her before they tortured her." Leo says while staring at his bowl.

"It isn't your fault, my sons. What counts is that you saved her from that dark place." Splinter says.

"I-I guess your right"

"Can we go see her now?" Mikey says with a big smile.

"She's probably afraid to come out. I mean, look at us! We're mutants! She was probably mutated into a lizard." Raph answered while playing with his spoon.

"Not really. Last night, she wasn't freaked out when she saw me and Splinter. She was actually... calm." Donnie said.

His brothers looked at them in shock. Why wasn't she scared? Mikey had a big smile in his face and yelled,

"Awesome! Finally, a person who won't be scared from us for the first time!"

Suddenly, they heard footsteps coming from the living room. They turtles all walked to see who it was. It was the girl. She was exploring the living room, her eyes looking all over the place. In the light, she was actually beautiful to see. Her blue pale eyes shining with curiosity, her long wavy hair shining in the light, her tail waving slowly. The turtles got out of the trance and walked up to her. She turned to them with a surprised look.

"Good morning, ma'm! My name is Leonardo. But, you can call me Leo."

The blue mask turtle turned to his brothers.

"These our my brothers. This is Raphael, Michelangelo and Donatello. But, you can call them Raph, Mikey and Donnie."

"Hey."

"What's up, girl?"

"Hi again!"

In a second, she crossed her arms and looked at Leo in the eye.

"Ma'm? I'm not old ya know." She said.

"Oh! I'm sorry if i offended you! I-"

Suddenly, she giggled. It was kinda.. cute.

"I'm just teasing you, silly!" She punch him on the arm slowly. Like they were friends before.

They were surprised of her sudden gesture. But, Leonardo didn't mind.

"Anyway, it's nice to meet all of you." She said with a smile.

"I'm glad you are awake, child. And in a good mood." Splinter replied joining the gang.

She gave a shy smile at Splinter. Not really knowing what to say. Splinter smiled back. At that very moment, April walked inside the mutant's house. She walked behind the girl she has been thinking of the whole night.

"Hi!"

The girl jumped and face April. She turned and gave her a smirk.

"Do you usually try to scare the guest by hiding behind them?"

"Well! I-" April answered in embarrassment.

"Just teasing you, sweetie! What's your name?" The mutant girl laughed.

"My name is April." April smiled.

"Now that i think about it, you haven't told us your name." Raph said.

The lizard girl turned to the turtles and gave them a friendly smile.

"My name is Carmela." She answered.

Well, that's The End for Chapter 1! HOPE YOU LIKED IT!
