Here's my Teenage Mutant Ninja Turtles fanfic! It takes place in the 2012 series. It involves the mutagen outbreak from season 2, but from my perspective. I don't own any of the characters except my OC. Enjoy!
It was a rainy day on 2010s Island. Most of the people were indoors staying nice and dry, while others were outside wearing trench coats and umbrellas. Nikita was at a diner eating a hamburger with fries and a soda. She was staying at a motel on 2010s Island for an extended vacation. She wanted to visit her friends, the Ninja Turtles who lived in the sewers under New York City. She wanted to make sure they were ok after all that they've been through for the past few weeks. After finishing her meal, Nikita took a taxi back to the motel and went to her room. Once she was inside her motel room, she took off her trench coat and placed her umbrella on the floor. Then she opened a portal to the 2012 TMNT world.
Nikita ventured into the Ninja Turtles' home dimension in New York City. She saw the bright lights of the night sky and could hear the loud noises of the bustling city. She flew up into the sky and went to look for her friends. She flew across some buildings until she spotted someone on the ground. Nikita landed on the rooftop of a building and quietly spied on the person. She knew who that person was: it was her friend April O'Neil or at least her former friend.
"April. Wonder what you're up to today." Nikita said to herself.
She spied on April from a safe distance away so as to not be seen by her. She wasn't ready for a full confrontation with April yet as she knew she was still harboring a grudge against her and the Turtles. So Nikita had to be very careful not to let April see her so as to avoid a confrontation. She watched her leave the library with a teenage boy. This fellow was her new friend Casey Jones. This made Nikita furious as she believed April had replaced her and the Turtles with someone else.
"Who does April think she is?!" She said with contempt. "She thinks she can just go and make a new friend just like that?"
Nikita followed April and Casey around while carefully and safely not making a sound so they wouldn't know that she was stalking them. She watched them study together in the playground on the swing set from the rooftop. April was teaching Casey all about Biology while he listened closely.
"Are you getting all this, Casey?" She asked. "Got it all: Deers, Birds, and everything else on the list." Casey said. "Great! Looks like you're actually catching up on our sessions." April said. "Awesome! I'll be able to stay on the hockey team for sure." Casey said.
The two teenagers continued talking about their study sessions, unaware that Nikita was watching them from afar. Even while she was far away from them, Nikita could still hear her ex-friend and her new friend from a distance. She watched with bitter contempt as April talked to Casey on the swingset. She still couldn't believe that April had found a replacement for her and the Turtles. Nikita remembered how Donatello reacted with sheer jealousy over April seeing another boy behind his back. She could still remember the sadness in his voice when he said April would never be their friend again because of Casey.
"Donnie, I hope you're doing okay. I know that times are hard, but we'll get through this together." Nikita tells herself. "Or maybe not."
She thought sadly about her friends. She knew how bad they felt after all those mutagen canisters fell out of the Kraang ship. Nikita could still see the sadness on Donatello's face when April walked out on them. She blamed them for the incident that caused her father Kirby O'Neil to mutate into a giant bat. Ever since that incident, Donatello's been trying to work on a cure for Kirby in the hopes that April would forgive him and become friends with him again.
Nikita continues watching April as she continues to tutor Casey on his schoolwork. She watched as they talked to each other and laughed. She felt a huge amount of rage inside of her. She wanted to go down there and give April a piece of her mind, but she decided not to do so yet. Nikita feared that if the Turtles would find out that she confronted April, they would be very upset because she'd only make things worse between them. She decided to wait for the right moment to confront her ex-friend about her attitude. For now, Nikita spied on the two teens one last time before leaving to meet up with the Turtles.
Nikita flew over a few tall buildings before landing near an alley away from nearby pedestrians. She walked towards a sewer drain and opened the lid. She entered the sewers and closed the lid so no one would get suspicious. Nikita walked a few miles down in the sewers until she saw a bright light ahead. She had made it to the lair of the Ninja Turtles where her friends lived. She walked into the living room where she saw Leonardo and Michelangelo watching tv. Raphael was playing with his punching bag while his pet turtle Spike was eating a piece of lettuce.
"Hey guys!" Nikita called out. "Hey Nikki!" The 3 brothers said in unison. "Where's Donnie?" Nikita asked. "He's in his lab working as usual." Michelangelo said. "Thanks, Mikey." Nikita said. "No problem." Michelangelo said.
Nikita walked into the lab where Donatello was doing some experiments with a batch of mutagen. She walked past Timothy who was still frozen in his tank. Donatello was too busy working on something to notice Nikita standing behind him.
"No, no, no! Still not right!" He said angrily. "Still haven't found a retro-mutagen yet?" Nikita asked.
Donatello nearly fell to the ground after hearing Nikita behind him. He got up and turned around.
"Nikki! Don't scare me like that." He said. "Sorry. Didn't mean to scare you, Donnie." Nikita said. "Oh it's alright. So how is April?" Donatello asked. "She's still hanging out with that boy." Nikita said. "How's it going with the experiments?"
Donatello pointed to a group of failed retro-mutagens in the corner of the lab.
"Still haven't found a cure yet, but I'm not giving up." He said. "I won't rest until I've found a retromutagen to return Mr. O'Neil back to normal. Then maybe April just might forgive us and we'll be friends again."
He turned around to face Nikita and placed his hands on her shoulders.
"I WILL find a cure and I WILL win April back no matter how long it takes." Donatello said with pride.
