A/n: Hey, so this is my first fanfic. And I would like to talk about my story just a little bit. It's part of a series I'm working on, and it's like rewriting a few TMNT 2k12 episodes. But they all play a part in each other. So this a rewrite of The Deadly Venom. So the idea with this was "What if Miwa had lived with Hamato Yoshi, Tang Shen, and four younger brothers her whole life? And then see how it would play out in The Deadly Venom." Well this was the result and I'm sorry if it feels a bit rushed. I apologize for any grammar mistakes. I'm still learning. Feel free to ask me any question on my story, and I'll the the best I can to answer without spoiling it.

Disclaimer: I don't own TMNT, it's characters, or its episodes.

Happy Thanksgiving!

Miwa watched in absolute horror as Shredder grabbed Raph by his throat and hung him over the side of the roof.

"No! Wait! Stop!" She begged as the Shredder's attention shifted to her.

"Mi… what are you… doing?" Raph gasped. Miwa looked around. She knew there was no possible way that they would all live through this. She looked at Leo who was struggling to stand, Mikey was on the floor unconscious, and Donnie had gotten swatted into the wall like a fly.

"Let him go, please… and I-I'll come with you." Miwa said with her head down not wanting to look into her brother's eyes. That sentence snapped them all out of their defeated state and sent them into a defensive one.

"No! Nee-chan, you can't!" Leo protested with Donnie following saying that she was crazy.

"Sis, don't go with him! Please!" Mikey beg shouted as Donnie supported him to stand.

"Mi, no… we'll figure something else out… I… won't allow this." Raph said as he struggled against Shredder's grip. Shredder on the other hand, was very interested with what she was saying.

"We're out of options, I'm not let any of you die on my watch… it'll be okay, I promise," Miwa said. She then turned her attention back to Shredder. "Now let him go, and I'll come with you." She demanded. Shredder thought for a second.

"Consider it a deal." Shredder said as he dropped Raph back onto the roof causing his brothers to run over to him. Miwa on the other hand was standing by Shredder, relieved that her brothers were safe. Tiger Claw approached them.

"We are taking her with us." Shredder said. It took the four teens only a minute before they attempted to get their sister back. However, they only got three steps in, until Tiger Claw created an ice wall dividing the two groups. The boys knew that they were in no condition to start a fight, and they were worried what would happened to their sister if they went after them. With a heavy heart, they went home to explain the loss to their parents.

Miwa struggled against the restraints that strapped her down to the lab table. Heck, if they weren't so tight, she could kick Baxter's head clean off... once she slipped out. In the past two days, Shredder accidently mutated her into a snake. She managed to escape and slithered out of the building into the streets. Soon, it became an attempt for a rescue from her family, and an opportunity for Shredder to try and kill her father. Which ended horribly for her, as she was caught in the crossfire, which led to Shredder getting a hold of her once more. Then after Baxter's failure to turn her completely human, she became a human that could transform between her full mutant snake, or if she wanted, a half human half snake. It's been a crappy two days and she was mentally preparing herself for the brain worm that would be implanted into her head.

"Let me go!" Miwa screamed. "Let me out of here!" As she struggled even harder. She heard footsteps walking towards her.

"If I recall correctly, you said you would come with me," The deep malevolent voice said as he came into view.

"What, do you want with me, Shredder?" Miwa demanded wanting answers.

"I want you to destroy everything Hamato Yoshi built, including his sons." Shredder said now standing directly in front of her.

"Why would I do that? He's my father!"

"You will do what I say, Karai. Soon you will see things my way and join me."

"My name is Hamato Miwa! Hamato Yoshi is my father, his sons are my brothers, and you can't change that!" Miwa yelled in absolute rage.

"We shall see about that." Shredder said. There was no doubt in Miwa's mind that he was smirking behind his helmet. "Stockman, is it ready?"

"Yes, Master Shredder. It'll work like you want it to."

"Give it to her." Shredder said turning to Miwa's direction as she began panicking causing her to struggle even more as tears filled her eyes. She watched in absolute horror as Baxter walked over to her, holding tongs, which held an oversized worm in them.

"No! Stop! When I get out of here, I'll kill you myself! You'll never be my father!"

Baxter ignored the teen's protest and put the worm in her ear, and when she felt it enter her head, Miwa let out a scream of pain and anger as the worm took control of her brain. As soon as it entered, Miwa's head hung down, she stopped struggling, and she didn't scream.

"Tell, me child, are you beginning to understand the way I see things?" Shredder asked. Miwa rose her head up and opened her amber eyes.

"I understand perfectly." She said with a menacing tone. Baxter pressed a button and the restraints that once held her, now released her onto the ground.

"Now, tell me. What is your name?"

"My name is Karai, Father." She said with a smirk on her face.

"And your mission, Karai?"

"To destroy everything Hamato Yoshi built, to kill his sons, their friends, Hamato Yoshi himself, and demolish everything they stood for." She said with venom on her tongue as she spoke with complete hatred.

"Very good my daughter." Shredder said as he walked to exit the lab.

Miwa wanted to scream. She wanted to wake up from this nightmare, but it was reality. Her actions weren't her own, same went for her thoughts. She was now Shredder's puppet, because she knew she was no longer in control… Karai was, and there was nothing she could do about it.
