Thug, Sludge Villain and Bakugou

(Time skip 4 years)

Every day I train my Taekyon and did a one punch man work out today is also one of those days suddenly while I'm practicing the trainer from the dude enter the gym then suddenly came to provoke me "Oh so you were on that come here every day huh I come here to see a big shot or so I thought it's just a kid" he said with a smile on his face trying to provoke me "Sorry sir I don't mess with someone whos weaker than me" I said with a smile on my face, Suddenly a vein on the side of his face "Say that again you freak" then he tried to grab my collar which I dodge easily.

.....

(Trainer A)

I'm talking to my friend in the gym then suddenly a middle-aged looking man come into the gym and start provoking the Youngman I haven't go to talk to him yet but I have seen him come here and once you saw a Youngman kick a wooden dummy in half you knew that he's not your average Joe,

I start sweating wanting to know what will happen next but as a trainer at the gym, Work come first so I walk to the thug(I will start calling him thug now) and try to come him down but then...

"how about a sparring then?" Grey said with a smile

"Sure I will break every bone in your body," the thug said with a smirk.

both of them then proceeds to go to the sparring ring

"Ahem both side will not use their quirk and after the opponent gets to knock out or forfeit the match will immediately end, "I said noticing people starting coming around the area.

(Thug pov)

a Smirk appears on my face heh he doesn't know that my quirk is multiplying my strength by 5 time nobody knows so I will wreck him, cracking my neck and rush at him aiming at his face with a right straight punch. suddenly...

(3rd pov)

everyone saw it the middle-aged man sent out a straight jab with his right fist then suddenly got dodge Grey then proceeds to swip his opponent leg and did a strike with his punch then after each punch hits he proceed using his elbows to deal a second blow attack after attack {Torrential Strike} until his opponent hit the ground Grey the end his attack with a hit to the shin and proceeds to go to the changing room.

Everyone leaving everyone in shock

(Grey pov)

Hmm, the fight is super boring his punch he didn't even prepare when he got counters to let's just go back to my house he then proceeds to wear his usual white T-shirts+jacket with a tiger at the back(he thought that it look cool) and blue jeans with his sports shoes.

He then spots the crowd gathered at the scene Bakugou trying to get away from a villain that trying to rape him and the heroes who standby waiting for All might to solve the problem seeing this annoyed him and the street that is happening which is the way back to his house.

Beside him, he saw a boy his age with mossy green hair sweating muttering under his breath "This is my fault and they can't do anything so they are waiting for any heroes with an 'advantageous quirk' quirk to come!"

It's my fault It's my fault ITS MY FAULT!!! recalling when he clinging All Might and the bottle that captures the villain probably fall out of All Might pocket he then he starts running through the heroes "No Stop the villain still got the boy captured" the hero said to Midoriya

The tension increase when the boy with green hair suddenly starts running to the villain then throwing his backpack at the villain and tried to free his friend? suddenly a boy wearing a jacket with a tiger at the back appeared near the villain {Bo-Bup} kicking the villain eye {Roundhouse kick} then the figure came the Number 1 hero came in and punch the monster "Detroit Smash!!" hurricane formed itself and Grey amused seeing the sheer power of the punch and after the event ended before our green hair Mit...Midoriya could say thank to him Grey use {Bo-bup} and teleport out of the place before anyone could ask him anything Grey then proceed walking home thinking of his dinner and the force pack in All might punch as he realized that he needs more training if he wants to reach AllMight level of combat.

After he got back home he noticed a similar exploding teenager in his living room "Ah ITS YOU!" seeing him with Mitsuki-san 'weird huh his mom went to visit us from time to time but I saw him around and.... wait how did you come here before I did?

"Oh so you're the one he talks about" His mom smile at him with her glowing red eyes that sent shivered to his spined

"let me thank you again for saving my son Grey"Mitsuki proceed to thank Grey

"Wait DIDNT YOU SAID HE'S 'BONK' " before Bakugou could finish his sentence he got bonk in the head "It's rude to shout in the house," Mitsuki said

"Mom how about I go to play with Bakugou-san so you could talk with Mitsuki-san?"

"Who wants to play with you!" Bakugou

Grey then use {Bo-Bup} disappearing from his place and appearing behind Bakugou then said "how about a spare?"

Mitsuki then proceeds to ask his mother " Ichika-san isn't Grey quirkless?" (I just think of Grey mom name so don't be confuse)

"That isn't a quirk Mitsuki-san that's his so-called 'technique' he created, "His mom said surprising both Mitsuki and Bakugou

"and Grey don't use your technique in the house would you?" said with a smile on her face

"Isn't this nice Katsuki you going to have a friend going to UA, "Mitsuki said

Ignoring his mother said "let's go" Bakugou said excitedly that he gets to fight.

"~sure," said Grey said before leaving both their parent said that doesn't come back with a bruise to both of them said that they won't

After sparring with Bakugou I'm quite surprised I noticed he didn't use his quirk and his form is not sloppy I remember in the anime he relly on instinct but this Bakugou actually knows martial arts and from what I see he has a lot of fighting experience too so knowing that he will not be using his quirk I hold back and didn't use my leg.

the sparring ends when the sun is down and we went back with no injuries.

...

after I hang out with him since our parents told us to I think we are friends? meh maybe.

Author here! I want to says that I will change Bakugou (his ways of thinking, personality,etc.) I will explain in the battle trial.
