(Hiya! This is a my hero academia/ boku no hero academia story. This One is where Bakugou ended up being sent into a different version of his world where it seems like he and Izuku swapped places. He became a child again as a result.)

Katsuki Bakugou has been through a lot and processed a lot. He was prepared for some unusual shit. But, he wasn't prepared for something like this to happen.

The last thing he remembers was fighting... Izuku was beside him almost the whole time, them working together to fight the villains... And then a flash of bright light invaded his vision followed by screams.

It was pretty dark for a while afterwards. And then... Another light. Not as intense as before.

He remembered flashes of colors next. And soon, he was able to figure out what the colors were.. they were people, sights.. He then realized that he was a child again. He wasn't even two yet... Nor was he able to to speak fluently. It was like whatever happened to him reset the whole world...

There was also differences, unlike what he remembered. His mom and dad acted differently. His mom was calmer and his dad more serious. His dad was still timid, don't get him wrong.. It was just that he seemed to have a CEO type personality now . That led him to realize how... Different he himself was.

He never felt even an ounce of aggressiveness inside of himself, no matter how much he tried... No matter how much he clung to the memories of a past he was no longer in, he couldn't bring it forth. He even tended to act similar to how Deku was when they were younger weirdly. It confused him as to why.

And then he met Izuku Midoriya... er, well , this Izuku anyways. He then realized how much stuff has changed....

Katsuki hummed as he walked beside his mom, a wide smile gracing his face no matter how much he tried to hold it back. He.. Wasn't used to smiling like he had no cares in the world.

He was holding her hand, seeing as how she would tighten her hold when he tried to pull away. So, he left it alone..

He was three years old now, his mom was taking him to the park.... Yeah, it still felt weird being resetted. Especially since everything seemed.. So different then before.

He blinked when he saw a familiar mop of green messy hair while walking..

Wait, his mom was walking up to a familiar green haired woman...

He could recognize that the woman was Deku's mom... Meaning...

He glanced over to the boy sitting in the sandbox making sandcastles... Yup, there was Deku. He seemed different though. Same with Mrs. Midoriya.

Mrs. Midoriya seemed... Tired. Aggravated. And Deku... Katsuki couldn't quite figure out what was different.

Katsuki's mom lightly pushed him forward, where he stood awkwardly as she introduced him.

She spoke cheerfully," Inko, This is my son, Katsuki... Katsuki, say hello."

Katsuki waved shyly, mentally slapping himself in the back of the head for acting timid as he spoke quietly," H...hello..."

Izuku had paused in the sandbox, now staring at Katsuki with an unreadable expression. Katsuki started sweating nervously, not even sure why the stare was bothering him so much.

Inko managed a smile, although it didn't quite reach her eyes.. She then spoke," It's nice to meet you..." Inko pointed towards Izuku, speaking with a neutral tone," Mitsuki, that little gremlin over there is my son Izuku."

Izuku stuck his tongue out at his mom while glaring.

Katsuki furrowed his brows perplexed, not used to seeing the green haired nerd acting this way...

Katsuki's mom pushed him towards the sandbox gently while saying," How about you go play with Izuku?"

Katsuki only nodded, quietly walking over to the sandbox before sitting on one side of it while Izuku was on the other.

Their moms were now talking to eachother while sitting on a park bench nearby, keeping an eye on the two while they caught up.

Neither Katsuki nor Izuku spoke.....

At least, that was until Katsuki decided to say something,"... What do you think about Heroes...?" He didn't really know why he asked.... But at least he could start trying to see just how different Deku was. Katsuki messed a bit with the sand in front of him while waiting for the answer.

Izuku had a wide grin form on his face, him speaking seriously," I think they're awesome. I even want to become the best hero there is."

Dajavu filled Katsuki at Deku's words... Except... It seemed like that was what Katsuki would've said... Huh.

Katsuki tilted his head slightly," You do?"

Izuku nodded , his grin becoming wider as he spoke," Yeah! What about you?"

Katsuki managed a bright smile, mentally cringing and asking himself inwardly why the hell he was smiling like that as he responded," I also think that they are really cool! I want to be a hero too!"

Soon, they were talking like best friends would.. It felt strange to Katsuki at the very least.

He finally noticed a few things about what made Deku different. For one, he acted like what Katsuki did... He had the confidence and everything, which weirded Katsuki out to no end. And Deku's eyes weren't fully wide like usual.. They were more slanted, like what Katsuki's was... Katsuki had noticed early on that his own eyes were more like Deku's in this weird reset.. Wider, brighter.

For now, he is gonna make a theory that for some odd reason, Deku and him switched personalities.... If that was the case... Would they have different quirks now?

He honestly hoped that he would still have his explosion quirk..

Soon it was time to go home. Katsuki smiled, waving at Izuku while exclaiming," See you soon!"

Izuku waved back, a grin on his face as he responded," You too, Kacchan."

Katsuki froze in surprise, his hand motion slowing. Did... Did Izuku already start calling him by that nickname??? ... Katsuki was pretty sure he started calling Deku Deku a few years after meeting the green haired kid... Huh...

Katsuki mentally shook himself out of his surprise, continuing to wave as his mom and him started walking again. Katsuki lowered his hand after a bit, glancing back one time.

Izuku was standing by his mom, watching them leave. Katsuki quickly looked forward, face turning red slightly. He didn't even know why he became so... Embarrassed?

Luckily, Katsuki's mom didn't notice, too busy talking to his dad on the phone about the meeting.

He has to find out why this happened... He just HAS to.
