Bakugo's POV:

Being reborn sucks, being reborn as the brutal bully of Kaboom Bakugo Katsuki? Not so bad, I knew the story, I knew what quirk I'm getting and can plan around it. I knew I'd be childhood friends with Deku aka Izuku Midoriya. And I knew how not to fuck up our soon to be relationship. Though I wonder, did Deku have a quirk and it was stolen by his dad or not? By the time I got my quirk I had plans for how I was going to train. Why I didn't expect... was to get a second one. Basically I had Explosion and a Quirk that gave me the powers of a Tanuki. Illusions, shapeshifting, and a few other things. . . This... wasn't in the plan, but more tools isn't a bad thing. It was about a month later when Inko said Izumi, yea Deku is a girl apparently? Izumi was announced quirkless, but something didn't sit right with me...

Katsuki: "This is the x-ray?"

Inko: "Yes, it's of Izumi's foot."

Katsuki: "No it's not?"

Mitsuki: "Shut up boy! What do you know?!"

Katsuki: "Well I know this is an x-ray of an adult's foot and not a kid's."

Pulling up an example on my mom's phone I showed them what I meant.

Izumi (Izuku's) X-ray

X-ray of a (quirkless) Child 

Katsuki: "See the bone's are..."

Inko: "The bone's are different completely..."

Guess that settled that, Deku had a quirk... and it was stolen...

Inko: "But why? Was it a mistake?"

Mitsuki: "Doesn't seem like a mistake a doctor should make... what if... Izumi had a quirk? Wasn't there that rumor of people getting their quirks stolen?"

A chilling air of silence overtook the room, Aunty Inko ended up crying for a long time while hugging Deku. She apologized again and again, saying how horrible a mom she was to give up on her so easily. That pissed me off, one little word from a doctor was enough to make her give up on her kid?! I don't care how nice Inko is, that's fucked up. It was at that moment, I promised to make sure Izuku... Izumi? Deku to make sure Deku got One For All and became a hero.

== Time Skip ==

I had to be a dick to Deku, is what I would have thought if I were stupid. Deku's a self sacrificing idiot! All though Elementary he stood up for anyone he could, right before Middle school he came out of Trans. Though I have to wonder, are they trans or just think being a guy will help them become a hero... Either way I support them, I even help them do training with like weights and stuff because of that their body is more masculine while still being feminine, which they love and hate. I think they maybe Genderfluid and not FTM, but I'm not going to say anything. Not my place, what is my place is kicking the teeth in of who ever touches Deku inappropriately~! 

3rd Person POV: 

Izuku was dragged into the boy's restroom by a group of three teens, and half slammed half pinned to the wall. A small fearful squeak escaping his lips.

Bully: "Damn even sounds like a girl."

Izuku: "I-I-I-I'm a-a-a b-boy..."

Leader: "Really? Mind if I check?"

The leader had his minions pin Izuku's arms and legs to the wall, before he slipped his hand into his pants and underwear. 

Leader: "I boy huh? I don't feel a dick, or balls, maybe they're in this cave down here."

He roughly pushed into Izuku causing him to shriek in pain, one of the bullies covered his mouth before Bakugo burst into the bathroom. Rage painted the blonde boys face as he began beating the three of them. Bakugo beat them for 25 minutes before Deku was able to get him to stop, scared his childhood friend would kill the three of them if he wasn't stopped. Afterward the three were expelled but not before Izuku had to go though an embarrassing and thorough medical examination to confirm their story.

Izuku: "Maybe it would be better if I was just a girl.... not some freak..."

Izuku whimpered to himself as he curled up into a sitting fetal position.

Bakugo: "HEY~! You aren't a Freak Deku!" 

Izuku: "BUT.....!~"

Bakugo: "Remember when I gave you your nickname?"

Izuku nodded into their knees, before Bakugo pulled the smaller into a hug. Causing the boy to look up at his childhood friend... and blushing a bit.

Bakugo: "I told you it had two meanings, the first one is Useless. But the second is "You can do it", and I still think that. You can do it Deku, even if no one else believes in you, I will."

Izuku's blush grew as they realized something, he Really felt like a girl at this moment. No not just a girl, a princess, and Bakugo was her knight in shining armor. Maybe... she was a boy and a girl? Was that even a thing, Izuku decided to do a bit of research later... As for now, she let herself feel like a princess and snuggled up to Bakugo where it was safe, and warm. A bit later the slime villain incident happened just like in the original story. And like in the original Izuku got One For All, and got into UA. And after some lengthy self discovery, Deku came out once again to their family and close friends aka Bakugo, as Genderfluid Transgender. And right after, they confessed to Bakugo, who was taken aback back embraced them with a tight hug. 

Mitsuki: "You owe me 1 million yen."

Inko: "Nope you owe me 5 million, they're not officially in school yet so it's technically before Highschool."

Mitsuki: "God Damnit!~ You're right!"

Bakugo: "You bet on us getting together!?!?"

Izuku blushed heavily and hid in their hands and in Bakugo's chest, best/most embarrassing day ever. Now the only issue was.... what school uniform does Deku order? The answer... was both, as UA's rules involving Trans/non-binary students were very open and inclusive. And not the fake inclusive either, the real inclusive. With specially marked restrooms, locker rooms, and medical facilities for trans and non-binary students. Deku could be a guy and use the FTM restrooms and locker rooms or go as a girl and use the female restrooms and locker rooms. Though Izuku was shocked when she walked into class the first day and see.....

Izuku: "K-K-KACCHAN?!"

Katsuki (Female voice): "What? You're not the only one who's genderfluid y'know. Can't like my adorable partner have all the female fun around here!"

Iida: "I find this conversation totally inappropriate for class~!"

Katsuki: "Pull the stick out off your ass Richie Rich! If LGBT conversations offend you then you need to toughen up!"

Aizawa: "I actually agree with that, but get into your seats. Class started 4 minutes ago."

Everyone looked to the front of the class to see a man in a sleeping bag laying on the floor. The man slowly got up and slipped off the sleeping bag. Deku and Bakugo the only two people who knew who the man was. Much to Aizawa's shock, but he shook it off and instructed everyone to go get changed into their PE uniforms. Stopping Bakugo from leaving to talk to her.

Aizawa: "I read your file, but can you confirm your biological gender physically changes?"

Bakugo: "I mean you can have a nurse check me over if you want but, yes I can confirm it does."

Aizawa: "Okay, just try not to make it weird."

Bakugo rolled her eyes and left to change, Izuku being more nervous than she was to change in front of people.

Bakugo: "Come on Deku, it's just changing your outfit."

Izuku: "Easy for you to say... I never changed in front of people before."

Momo: "Never?"

Bakugo: "Our old school was... wasn't good with trans people. They tried making Deku change in the hall so she'd "be a real girl and use "her" appropriate locker room instead of a weirdo." It was awful..."

The girls all frowned and comforted Izuku, none of them were able to image that kind of treatment.

Mina: "Soooo Kate..."

Bakugo: "Who me?"

Mina: "Yup, that's your new girly name! So Kate, you're genderfluid like Izuku?"

Bakugo: "Yea except it's more thanks to my quirk than anything."

Uraraka: "What do you mean?" 

Izuku: "OH, OH~! Kacchan has two quirks! One is Explosion! She sweats a nitroglycerin like substance that she can detonate! And has another one that doesn't really have a name yet... it changes her gender randomly or it can."

Bakugo: "Ha, ha, ha! Yea imagine my unholy shock when I was like 6 and woke up as a girl for the first time! It was as funny and chaotic as you'd think." 

Mina: "Ha, ha, ha, ha, ha! Did you run to your parent yelling how your thingy was gone?"

Bakugo: "Bingo~!"

The girls all got a good laugh out of that and before long everyone was outside and did the test. One where... shocker Mineta failed and was expelled, only for him to worm his way into 1-C somehow. Poor Shinso, like he didn't have it bad enough. Just kidding, Shinso was able to make it into 1-A thanks to reasons. (Cause the author fucking said so that's why~!) After a few days at UA it was time for the USJ trip... And the first appearance of the League of Villains....
