Boom Boy.

A/N: katsuki can create explosions depending on his stamina and he can enhance then relying on his sweat which is Nitro glycerine this is his greatest limitation. In order to release sweat we need to exhaust ourself. But his cheat bypasses it and allows him to create sweat without any exertion, he can also enhance the amount of sweat he wants to generate or completely stop his sweat generation. Finally the produced sweat of his can be perfectly controlled by him. Now since the speed of his sweat formation is fast since it's a secondary quirk imagine him creating litre worth of sweat and directly moving it on his palm and concentrating it there. Then igniting all of it at once. The explosion would be disastrous and would even have the properties of plasma.

It would be similar to genos incinerate if you know what I mean.

" You should try to be more careful brat " said a blond haired women who looked to be in her late twenties.

' She's bakugou's... My mother now, Katsuki definitely took after her ' thought our protagonist while getting himself dried off by mitsuki.

' How should I answer to her?, I don't know if bakugou already had developed the hereditary personality. I have no choice then to go with a balanced approached '

" Hn " katsuki grunted.

Smack!

" I'm pretty sure I teached you how to speak brat. " Yelled the blonde women

" Tch, I'll be carefull " replied bakugou while rubbing his head ' did i do it right, well I guess I did '

" So if i may ask, why did you punched izuku in the face? " Mitsuki asked with a challenging voice.

" He was awfully close, it made me uncomfortable " katsuki replied while sweating buckets.

" Mitsuki leave him be, he would only grow when he leans to fall " said a male voice katsuki recognised as masaru

" Don't try to divert the topic, izuku was just trying to help him. " mitsuki said with a frown

" Inko was upset about it ".

" Accidents happen sometimes... Well if he doesn't learn to fall then he won't learn to rise " said a wise voice

" Oh I still remember you screamed more than me during my labour. The faces of nurses were hilarious " mitsuki said while trying to surpress her laugh and failing miserably

" Dear let's not talk about it in front of katsuki " mararu said with a pleading look.

' He already diverted the topic without mitsuki realising... I can guess how he survived soo long ' thought katsuki, now starting to form admiration for his dad

Mitsuki then looked at him " Brat this shouldn't happen a second time or.. " she rubbed her fists scaring the shit out of katsuki.

' Wait... I'm a 16 year old teen, I refuse to be treated like this ' he looked straight at mitsuki only to back down as a glare was sent his way

' I am 6 ' katsuki thought accepting his fate.

Masaru seeing this smiled proudly ' you are a fast learner, as expected of my son. '

The next day~

Currently we see katsuki wearing a unrecognisable expression. If izuku were to see this expression he would have been down right terrified.

This expression is only made by katsuki when he's irritated... When he's really really irritated

' Whose idea was it to reincarnate as a 6 year old. I'll have to go through elementary school again, and that's not even the biggest issue '

Katsuki thought while watching a kid crying because he fell over his butt. He let out a sigh of relief ' atleast I don't have to go through nursery '

' Okay so let's see. I'm currently 6 year old. I have about 9 years before I join UA, and I have 11 years before the final war shit. '

Bakugou thought while sitting in the shade of a tree as currently the lunch break was going on.

His gaze then fell upon izuku being bullied by the ' bakugou's goonies ' from original. ' I guess I'll help him for once. But this would be the last '

Bakugou stood up as he made his way towards the bunch with slow footsteps.

They also noticed him as one of the fat one who held a arrogant look said with a smirk

" Bakugou you can choose someone else, deku is ours "

Bakugou gave him a blank stare and replied

" You never do anything halfway do you? "

He looked confused ' And yes why would he understand ' deku couldn't help but let out a laugh at such a indirect insult

The fat boy quickly got angry as he yelled at deku " you know what it means right?. Tell me now "

Bakugou sighed " I'm implying that you have never missed a meal in your life " he finally understood as he unlocked his wings quirk as he ran towards me.

" Guess those wings aren't built for heavy lifting, huh? " This was the switch which made everyone present unable to control their laugher.

The boy face flushed red with anger but I simply lifted my hand as few sparks started to form there which made him stop on his tracks and back away.

His lackeys realising the situation also fled with him. I looked at Izuku who was sending me a thankful look and said " Don't expect me to help you all the time deku. It wouldn't end untill you learn to stand up for yourself "

With that I left leaving izuku to his own thoughts.

' Now how should I start my tranining?, it would be stupid to go arnold at the age of 6. While I can still do stamina traning. '

' I'll also have to train my explosion quirk and more importantly my sweat manipulation which from now on I'll call Sudohesis. '

Bakugou opened the last page of his notebook as he completely ignored what else was happening in the class.

TRANING PLAN:-

1) Stamina traning.

2) Slight strength traning .

3) Spamming as much explosions as possible

4) Sweating a Lot. (A lot)

Timeskip~

' It's been 4 years and I've finally turned 10. Still have 2 years of elementary school tho. '

' many things have changed for me. ' thought bakugou with the same scowl he had 4 years ago.

' I have improved in stamina and strength. My explosions are now quite strong as well. '

' The most improvement I have had in is my Sudohesis. Now I'm able to create almost 1 litre worth of sweat in a matter of seconds. '

' The biggest advantage that my Sudohesis gives me is that I can create sweat without exhausting myself. This means I don't have to wait for my Nitro glycerine sweat for form to ignite more powerful explosions. '

' Not only that, i can also control the sweat formed. For example moving all the sweat formed around my body to my palm and concentrating it there. '

' Concentrated Nitro glycerine on ignition releases a explosion with almost plasma like abilities. I can already imagine myself reciting 'I am atomic' while fighting shigiraki and kicking AFO. ' katsuki thought with a giddy expression.

' Even now as a 10 year old I'm already capable enough to match katsuki when he took the UA entrance exam. '

' While I lack in stamina and strength of even natural explosions without sweat. I can basically abuse my Sudohesis to spam stupidly large explosions. I would not be surprised on having a nuke level trump card by the time I turn 15. Hehehehehe '

" Bakugou how do you pronounce this sentence in English "

" Tch "

To be continued~
