Prologue

The turtles were about to go on patrol. Leo wanted to train, Raph wanted to fight some kraang, and Mikey just wanted to get pizza. As for Donnie, he felt like he was the only one who wanted to find all the mutagen containers they had dropped. He was devastated when April's father got mutated into a giant bat from one of the falling containers. April made up with them, but Donnie still felt held responsible.
Leo was about to lift the man hole cover when they all heard a scream.

"What was that?" Donnie asked.

"Dunno," Leo replied, jumping down from the ladder. "But we're gonna find out. Come on!" The turtles rushed off to the area of the scream. The scream sounded again, this time closer. A few minutes later, they all saw a young girl, about 15, with brown hair, a tight white t-shirt, and dark blue jeans. She was fighting some foot bots, about 10 of them, and, by the looks of it, was doing it while injured. She was only using her left arm, avoiding strikes that were aimed at her right. The young girl saw she was outnumbered and ran off, the foot bots right on her tail.

"Come on." Leo half whispered. The turtles ran after them as they turned a corner. They all peered around the corner to see the young girl, her back against the wall, and a foot ninja about to strike her with a sword to the head. The girl curled up and hugged her knees, her eyes shut.

"Now!" Leo yelled. They all burst from behind the corner and attacked the foot bots. Donnie hit two with his Bo staff toward Raph as he finished the three he was taking on. He turned and sliced them. Leo slashed four and Mikey finished off one. Donnie looked at the girl who was still huddled in the corner.

"It's alright," Donnie reassured her quietly. "You're safe now."

The girl looked up and gasped, scooting closer to the wall. "You're… your… uhhggg…" She passed out.

Donnie rolled his eyes. "Of course…"

"Bring her to the lair." Leo told Donnie.

"What?" Raph exclaimed. "We can't just bring some random girl into the lair!"

"She's hurt Raph," Donnie said, picking her up.

"And Splinter always says, 'The enemy of my enemy is my friend.'" Leo reminded him.

Raph groaned. "Splinter Junior…" he muttered as they all headed back to the lair.

At the lair, Splinter came out. "Back so soon?" He must have seen the girl, for her narrowed his eyes. "And with a stranger?" he looked at Leo. "Leonardo…"

"She was being attacked by some foot bots," Leo explained.

"And she's hurt," Donnie added.

Splinter stroked his chin. "Very well… but you are responsible for her Donatello."
Donnie nodded and laid her on the couch while everyone left. He looked at her arm. Sprained… he thought to himself. He began working on it. Once he was finished, her arm was neatly wrapped in bandages.

"Does she have a name?" Leo asked, coming in.

Donnie checked her pockets and found an ID card. "Amelia Seiko, Age 15," Donnie read off the card. "The date says she got it today. She must be new in town."

Amelia began to stir. "Awwggg…" She moaned. Her eyes flickered open. "What a weird…" she gasped. "Dream…" she turned and saw Leo and Donnie, and screamed.

Donnie put his hands in front of him. "It's okay! It's okay," he told her. "We're not going to hurt you…"

Amelia panted. "Wh-What are you?"

"Turtles," Raph replied, walking in with Mikey.

"Ninja turtles!" Mikey corrected him.

"I'm Donatello," Donnie said. "These are my brothers: Leonardo, Raphael, and Michelangelo."

Amelia sat up. "I-I'm Amy…" she said uneasily.

"A.K.A. Amelia Seiko," Mikey said, grabbing her ID from Donnie's hands. "Age 15," he began reading everything on the ID card.

"Hey give that back!" Amy said. A small blue spark flew from her finger and hit Mikey's hand, making him drop the ID.

"How did you do that?" Donnie asked.

"Do what?" Amy replied nervously.

"That spark."

Amy crossed her arms. "I don't know what you're talking about."

Raph growled and grabbed her injured arm.

"Ow!" Amy screamed, a huge blue spark of electricity throwing Raph against the wall.

"Raphael!" Leo yelled, rushing over to him.

Amy stared wide eyed. "I-I'm so sorry! I-"

"Sorry my shell!" Raph grunted, getting up.

"I didn't mean to! Honest!"

"Yeah right!"

"Enough!" The voice of Splinter made Donnie jump.

Amy looked over at Splinter and gasped, obviously holding back a scream.

"It's alright," Donnie told her. "This is Master Splinter. Master Splinter this is Amy."

Splinter bowed. Amy hesitated, but bowed her head in return.

Raph was still full of anger. "Have you all forgotten what she just did?" He raged. "She just shocked the shell out of me!"

Splinter narrowed his eyes and Donnie. "She what?"

"I-It's not what you think!" Amy said, getting up. "I didn't mean to I just-" she stopped talking when Raph punched her in the face.

"Raphael!" Splinter yelled

Amy breathed heavily. Then a huge wave of electricity sent them all flying. Amy gasped, panting. "I…I…" She looked around, and then ran off.

"Amy, wait!" Donnie called, quickly getting up to chase after her. He heard his brothers calling after him but he didn't stop. He kept running. His mind was focused on finding Amy. He past a boarded off tunnel when her heard crying. He stopped listened. The crying was coming from the behind the boards. The tunnel had a hole, big enough for him to fit through, within the boards. He climbed through and saw Amy sitting on the floor, hugging her knees, crying.

"Hey…" he said in a comforting tone.

Amy gasped and backed up. "Get away from me… I don't want to hurt you…"

Donnie smiled. "My brothers and I have been through worse."

Amy sighed. "I don't know how to control it…"

"The spark?" Donnie sat down next to her. "How did you even get those powers?"

Amy sighed. "Lighting incident." She replied

"Owch…"

"Yeah... It hurt a lot. But when I woke up, those robots were surrounding me. They tried to take me but I ran into the sewers. That's about the time you guys showed up."

"Do you have any one to go to?" Donnie asked.

"I live with my sensei and my friend. But I cant go back... Not like this..."

"It alright. You have stay with us until you're good enough to go."

Amy smiled. "That's great. Though it might take me some time to get used to you guys."

"Especially Raph," Donnie added. "He didn't hurt your arm to bad, did he?"

Amy shook her head. "It's fine."

Donnie smiled. "Well let's get back to the lair." He said, the two of the, walking back. "I'm sure you have quite a story to tell Splinter."
