Heroic Betrayal

Training to Become a Vigilante!

A/N Imagine that Izuku is wearing a new outfit where she is training to become a Vigilante. She will be training for about half of the chapter in order to get her battle sense back to normal and will be meeting the Turtles in this chapter in a fight against them. I will try and make sure that the fact that Izuku will not trust them for very long is based on his past as well as the fact that she now will not trust anyone who tries to get close to her. Ships for this story is not decided at the moment, if you want a ship for this story, please leave a comment down below.

Izuku woke up this morning with violence on her mind, she had been very moody as of late and couldn't figure out why. And when she had been searching on the internet for what the cause was, she was floored when she found out that her period might be coming in for her. Meaning she will need to seclude herself for when that happens and that was when she felt her underwear get noticeably wet, and once she took them off to find out what that was, she found out that she was on her period as of that moment. "Fuck." She said, walking around her base. She was so angry at the problems that came about from her losing One for All and how she had been transformed into a mutant crocodile girl, that she never realized that she was starting to train in her training room. As she trained her body, she noticed how her anger was slowly warring off as she finished working off a sweat. She eventually managed to just end her training for the night before heading to sleep, and once she woke up the next morning, she realized that she would have to leave the area since it was ransacked during her slumber. Walking out of her little alcove she looked as she saw everything that she built ruined as she was furious at who done it. Looking at the wall on the side of her station, she saw that it was signed by Baxter Stockman an ally of Shredder. Looking online she found that Baxter Stockman lived within the city at his main building, but nobody even knew what he was up to all the time. Leaving her little home in the middle of the night, she prepared to take him on alone, all for the sake of getting revenge on the man who destroyed her little home. Stalking the alleyways at night, Izuku made her way to the building where Stockman lived and once, she was right in front of the main doors she punched her way through the glass doors as she took on the forces of Stockman all on her own.

===========================================================

On the rooftops nearby the building the forces of good are seen playing around with one another as they fight some of the Foot Clan as they move about the night. Collecting the mutagen that they have been collecting on their own in order to see if they could find a cure to those who have been under the effects of it. They are about to head home for the night as they hear the distinct sound of Baxter Stockman's building being raided as one of the four begin making a comment about it. "Donnie! Who is raiding the Stockman building!" One of the four asked. "Hacking into their mainframe now. Hm? It seems to be a woman with a crocodile quirk." The one who should be Donnie said, confused. "Did he do something to earn the ire of this woman?" One of them ask. "Not that I know of, but isn't this woman the one we found in our old base of operations?" Donnie asked once again. "I know that woman from somewhere. I just can't remember where." The other said. "Well how about we go and check her out in order to see what is going on." A brash one of the four said running off. "Hey, don't leave us behind!" Another said, running off. "Let's go there." The logical one said. With that they headed off into the night to see what was going on at Stockman's home.

==================================================================

Izuku was seen battling a seemingly never-ending army of robots as she bulldozed throughout the forces as she was screaming the name Stockman loudly. "STOCKMAN!" Izuku screamed as she crushed one of the robots in front of the camera just before destroying said camera. Breaking down doors as well as walls in order to increase her search of the man in charge of the building she soon finds him standing alone in his room with a look of fear on his face. "WHO THE FUCK ARE YOU!?" He screams in terror. "I am one of the new arrivals to New York... and you thought it was funny to mark your territory in MY LAND!" Izuku screamed as she grabbed the man with a fury in her eyes. For some reason she was so against killing people but for the simple fact that the man had entered her territory and got out of it whilst vandalizing her home made her wish to kill him before he could do it to others. Her size began to increase as she gained more reptilian features as Stockman realized that she was who Shredder was searching for all this time. "WHAT THE HELL ARE YOU DOING HERE! AREN'T YOU ON THE RUN FROM SHREDDER!?" Stockman yelled in fear. "Since I am about to kill a potential threat to my life as well as my home... My name is Izuku Midoriya, and I am the former Ninth user of One for All and I am the crocodilian Vigilante... Rowena Ula." Izuku said, as she snapped the man's neck before tossing him to his robots. She made sure that he would live with the fear of nearly being killed by her as a warning of coming near her home. She checked his pulse and found that he was still alive, and nodding in acceptance, she left the building just as the group of vigilantes arrived inside the skylight of the building.
