"Ok everyone, there are rumours saying there is a villain in the streets. Today's exercise is to look for them. They are a female around her thirty's. She has black hair and grey eyes. No one knows what her quirk is, so be careful. If you do encounter her please send your location and I will assist you. You are not to engage in any combat unless I say so. Got it Bakugo?" Said Aizawa (EraserHead).

"Yeah whatever," said Bakugo.

"You will be working in teams in a specific area, which I will announce now-

Team 1- Aoyama, Ashido, Koda, Sato and Sero. North.

Team 2- Mineta, Uraraka, Midoriya, Iida and Bakugo. South.

Team 3- Kaminari, Kirishima, Jiro, Shoji and Hagakure. East.

Team 4- Asui, Tokoyami, Todoroki, Yaoyorozu and Ojioro. West.

This villain is said to be very strong, just be careful ok?"

Here was a murmur of yeses through the class.

"Get changed into your hero suits and meet me at the front of the school." And with that Aizawa left the classroom.


Bakugo grabbed his hero suit and went straight to the boy change rooms. Why the fuck do I have to get stuck with that piece of shit, Midoriya. He thought to himself. Whatever I won't let him get in the way of me becoming the number one hero.

"Yes. We're on the same team, Kaminari." Said an exited Kirishima.

"Yeah I know!" replied an exited Kaminari.

Morons, do they have to celebrate so loud. Bakugo thought to himself.

"Hey Bakugo,"

"Yes Kirishima?"

"What kind of quirk do you think this villain has?"

"I don't know, but whatever it is she is going down."

"Yeah, that's the spirit!"

"Hey, do you think she'll be hot?" Mineta said drooling at the thought.

Midoriya was thinking about being on a team with Kacchan. "Maybe it won't be that bad," he gulped. "But knowing Kacchan, it probably will be. At least I'm on a team with Uraraka and Iida. Speaking of my other teammates, I wonder how Mineta will go. I hope he doesn't try to perve on Uraraka... Or the villain. Speaking of the villain we should try to figure out what her quirk…"

"Shut the fuck up Deku!" Said Bakugo

"Oh, sorry!" I didn't realise I was speaking out loud."

"Fucking shut up!"

Kacchan doesn't seem too happy about being on a team with me.


The teams met up outside at the front of the school.

"You better not hold me back dickheads" Bakugo said.

"You cannot speak to people like that all the time Bakugo," said Iida waving his hand at Bakugo trying to discipline his friend.

"Like I care,"

Uraraka put her hand on Iida's shoulder and smiled. He calmed down.

A bus arrived at the school.

"Now everyone, I want you to enter the bus in an orderly fashion." Said Iida ushering people onto the bus.

Uraraka sat next to Midoriya who was seemingly upset. "What's wrong? Is it Bakugo?"

Midoriya nodded. "I'm worried he will go off on his own."

"Well, you're not the only one who seem upset about this… I mean Bakugo doesn't look very happy either, we can only try to get along." Uraraka seemed very happy.


The bus slowed to a stop. "We are in the middle of the city, as you know. You may go to your assigned areas with your teammates. Be careful of civilians and remember what I said earlier." Said Aizawa extremely tired.

"Come on let's go!" Bakugo said walking off grumpily. Iida, Mineta, Uraraka and Midoriya followed.


"Where the fuck is this chick," Bakugo said aggressively. He walked along one of the main roads. A loud scream echoed in the distance.

"Over here!" Midoriya said running in the direction of the scream.

They ran into a dark alley, a woman with black hair and grey eyes stood over the body of a young girl. The girl was dead. The woman started laughing, "I'm Cinder," she cackled. "And who might you be?" She was visibly unstable. Midoriya stood there stunned. He looked at the wounds on the girl, her body had been shredded. "Enemies then," Cinder ran at them and pulled out a knife. She was getting ready to stab Midoriya. Iida jumped in front of him and tripped her swiftly. She rolled back onto her feet.

"That must be her," said Iida. "Send our location to Aizawa, Midoriya."

"No you don't," she made another attempt to stab Midoriya, but was blocked by Bakugo.

"You're going to have to kill me first," he smiled and blew an explosion in her face.

"You've got talent kid, it's a shame I'm going to have to kill you." She jumped back and pulled out a sword.

"We aren't supposed to attack her Bakugo." Said Iida.

"Shut up," said Bakugo. They began to fight. She held back as if she didn't want to kill him. They exchanged blows.

"Have you sent it?" said Iida. Midoriya nodded. Bakugo sent an explosion towards her chest and ripped her shirt. Mineta began to drool, "she's beautiful."

Uraraka slapped him, "she, is the enemy!"

"Damn, your good kid." She licked her lips. "I'm going to have to finish this soon."

"Stand down," Aizawa arrived. His hair was floating, he was using his quirk on the woman.

"I didn't think I'd be seeing you so soon. Aizawa." She looked up to see him standing on the building next to them.

His hair dropped, "C… Cinder?" He looked shocked. After he stopped using his quirk she jumped at Bakugo and planted a kiss on his cheek. "Huh... Get off me you!" He blasted her and knocked her out.

A cloud of smoke arose around Bakugo. "Huh?" his shirt ripped and he felt a strange weight on his chest. He looked down and the smoke disappeared.

"WHAT THE FUCK!"

Mineta looked at Bakugo, "HE HAS BOOBS?!" Mineta began to drool, "and there beautiful." His nose spurted out blood.

"Stop looking you little shit… STOP LOOKING ALL OF YOU!"

Todoroki's team arrived. Their mouths dropped. "WHAT THE HELL HAPPENED?!" They shouted simultaneously.

"Ba… Bakugo turned… into a… girl," Midoriya pointed at her. Yaoyorozu didn't waste any time and made and gave him a bra.

"Uh, Bakugo… can I talk to you?" Aizawa said. After Yaoyorozu made him a shirt he went to talk to Aizawa.

"Bakugo, I used to know that woman. Her quirk can change someone's gender. But she never figured out how to reverse it, so unfortunately you may be a girl for the rest of your life." Aizawa said. Bakugo began to tear up, "so I can't... I can't... Ever be a boy… Ever again?" she began to cry. "Dammit, why am I crying."

"Your emotions are going to change a lot, Bakugo. You may not know how to deal with this, but it's going to be OK. I had a friend who this happened to." Said Aizawa. "Let's talk to the rest of the class."

They walked over to where the class was after Bakugo stopped crying. Aizawa sent a message to the rest of the class saying they had captured the villain and to meet them at the bus. The class walked to the bus. Everyone in their own conversations, but Bakugo. She walked alone in the crowd. She was confused about her new body. Millions of questions and thoughts passed through her mind.

How will I explain this to mom and dad, damn. What about these feelings, I don't understand them, shit. This damned quirk of that woman.


She arrived at home. She went to knock on the door but hesitated. Damnit. She took a deep breath and opened the door. "Mom? Dad?" There was an awkward silence. "I am home."

They walked to the door, Katsuki's head was down. "Can… we help you?" His mother, Mitsuki, said. Tears filled Katsuki's eyes and dripped off her face. "I… I'm so sorry, I didn't want this to happen." She looked up. They immediately recognised Katsuki's face.

"Mum, dad," she threw her hands around them. They were surprised at first but hugged her back. Katsuki took a step back, away from the hug.

"K.. Katsuki?" Mitsuki questioned. Katsuki nodded to answer her question. "Come inside," Masaru took her inside and sat with her on the lounge. "Can you tell me what happened?"

"I got hit by a damned gender swap quirk. And there is no way to reverse it." His parents hugged her upon hearing this news.

Please review and tell me what you thought so far,

Also if you didn't notice when Bakugo is thinking the text will be in Italics.

Sorry about the language, but it is Bakugo. and sorry about the last bit if that confuses people, but seeing as though all their lasts names are Bakugo it could get confusing.

Cheers!
