In the UA locker rooms

Sero: "uhhhh... guys... have you checked the news right now!?"

Kirishima: "huh?!"

Lida: "why? What happened?!"

Sero: "there's a Dragon level monster attacking Nagano city right now!!"

Kaminari: "is there any heroes there?!".

Sero: "there is metal bat, Mirko, and..."

Meanwhile

The crowd were screaming as they began to run towards the opposite direction. The exit of the city. Metal bat was fighting elder centipede and Mirko was knocked out from her fight with Izuku.

Woman (screaming): "what happened to all the heroes?!"

Man (screaming): "Mirko's out, she's just lying on the ground unconscious".

Woman: "let's get out of here".

Izuku was walking forward, opposite of everyone else's direction.

Izuku: "well, well. Everyone's all excited. Threat level dragon gets announced, and boom... suddenly it's a party. I wonder if metal bat will still be alive by the time i find him."

Before he could think, he saw a person hurled towards him from that centipede. It was none other than metal bat.

Izuku: "huh? Metal bat... how'd he— oh that's how." he scoffs. "so, some other monster got to beat up an S-class, huh? I wasted my time."

However, much to Izuku's shock, Metal Bat promptly walks past him to resume his duel with Elder Centipede.

Metal bat: "*sighs* Back to the grind."

Izuku was caught off guard by the sudden encounter but regained his composure.

Izuku: "Metal bat, hold up you're not dead yet?!"

Metal bat: "huh?"

Izuku: "You being alive changes things." he laughs. "my second S-class and second Hero I hunt today. From here on, you face me. I'm hunting you." he said pointing at him.

Metal bat: "huh? Get real dipshit. Can't you see that giant centipede? Get your ass—".

Before he could finish his sentence, Izuku attacks, but Metal Bat raises his guard and repels him, marking the beginning of the battle.

Metal Bat: "now I see. You're that guy who's been running around, calling himself a hero hunter."

Izuku: "damn right. This monster won't fall to you". He laughed.

Metal Bat: "I'm guessing you already beat Mirko up. You can see I'm busy here. But sure I'll spare a little time... And crack you wide Open."

Meanwhile

Mandalay: "damn it..."

Pixie bob: "it's got us cornered".

Mandalay: "if we don't do something quick, we're dead". She said as she imaged kota's face in her head.

Before they could react, endeavour shows up and threws a few massive fire balls at the centipede but dispite this Elder Centipede remains undamaged by Endeavours attacks.

Endeavour POV: "not even a scratch, this one's gonna be a pain in the ass."

Elder centipede: "annoying misqito".

Mandalay and pixie bob began to run with the hero association executive on their arms.

Mandalay: "i hope kota's safe".

Pixie bob: "he's probably fine".

They got to safety after 30 mins of running

Meanwhile

Izuku strikes Metal Bat with his left fist, blowing Metal Bat back several meters.

Izuku: "guess you were worn down already. I wanted to see how tough you were, but i won't get a true taste since you're running on fumes."

Metal bat: "SHUT THE FUCK UP!!"

In anger, Metal Bat jumps and attempts to slam Izuku with his bat, but Izuku dodges and punches the hero across the face. He follows up with an elbow strike that nearly sends Metal Bat to the ground, but he manages to stop his fall by planting his bat into the ground.

Izuku: "all that blood loss, you'll probably pass out at any second. Not to mention you've got multiple fractures. What's keeping you standing? You're hero pride?"

Metal bat swings his bat horizontally, but Izuku jumps up and strikes Metal Bat with a right sidekick. However, Metal Bat is unfazed and engages in a succession of swings. with a loud yell, Metal Bat slams his bat downward; Izuku manages to evade the blow.

Izuku POV: "his swings are coming faster? More powerful too"

The force of his strike manages to not only destroy the ground, but a building in front of the hero as well.

Izuku POV: "that shouln't be possible".

The hero hunter uses his Water Stream Rock Smashing Fist technique and strikes Metal Bat with a multitude of blows. Metal Bat barges through his attacks and tries to attack Izuku again, but the hero hunter jumps back onto a fence.

Izuku POV: "with every hit he takes, everytime he gets hurt, he becomes physically stronger."

Izuku: "how do you even make sense?"

Metal bat: "screw makin' sense. I'm still pumped. It's about fighting spirit."

Izuku POV: "is he fr?"

Metal bat: "just come at me already, hero hunter. I've still got a giant centipede to deal with after I'm through with you!"

Izuku POV: "he's still..."

Izuku: "Let's see how long you can stay pumped up. I'll play with you for a bit."

Izuku plants his feet down on the ground and throws a manhole cover at Metal Bat, but Metal Bat deflects it with his bat right back at Izuku. Izuku dodges the manhole cover and pummels Metal Bat with a lethal barrage of blows.

Izuku: "i'm here! Dumbass."

Metal baat: "i got a personal rule to never let muggers or hero hunters off the hook. I'm gonna take that rotten spirit of yours and pound it into shape!"

Izuku: "swing and a miss, moron!"

Izuku deviously smiles and yet again pummels Metal Bat with his Water Stream Rock Smashing Fist. Metal Bat swings his bat down, but izuku catches the bat and slaps him across the face. What ensues next is a rapid succession of bat swings, all of which izuku is able to expertly dodge.

Izuku: "Is this your entire strategy? Just gonna keep swinging that thing til' you're dead?"

Metal Bat: "til' I'm dead? Ain't nobody got time for that. Til' i win." he got a stance. "Killer move: fighting spirit brutal tornado!

Determined not to let him get the best of him, metal bat unleashes one of his killer moves. The hero begins to gain rapid speed and momentum.

Izuku: "Huh? "you're just spining around in circles! Don't make me laugh." he laughed. "unfortunately for you, i can deflect every one of your amateurish blows.

Izuku does exactly this, perfectly intercepting all of the bat swings, and with a circular motion of his hands, guts Metal Bat in the chest, making the hero cough up blood and sending him flying back. This time, Metal Bat does not get back up, making Izuku conclude he was the victor.

Izuku (scoffs): "he finally went down."

Izuku POV: "Tank-top master and metal bat are both just musclebrains. They lack hand to hand-to-hand martial arts skills. Mirko on the other hand was quite the worthy opponent. Crushing the heroes might be a lot easier than i thought.

He raised his hands slightly to only see them shaking violently.

Izuku POV: "you've got to be kidding me. Did his attacks pack more of a punch than i thought?"

Izuku (cocky laugh): "i might've been in trouble if he'd mange to land one on me."

Metal Bat instantly gets up and prepares to swing his bat at Izuku while he was unprepared. Yet just before the bat makes contact with Izuku's head.
???: "ONI-CHAN!"

a voice calls out to Metal Bat. That voice is revealed to be coming from Zenko, Metal Bat's little sister.

Zenko: "Big brother bat..."

Metal bat: "tchh..."

Zenko: "what are you doing? who is that?"

Izuku (puzzeled): "his little sister?"

Metal bat: "ZENKO STAY BAC—"

Before he could finsih his sentence, Izuku hits Metal Bat across the face with his left fist, sending him back to the ground.

Zenko: "Oni-chan!"

Izuku: "you missed the perfect opportunity. This time... i'll finish you off for good."

he said as he cracked his knuckles. However, before he could land a hit, Zenko interferes and defends her big brother.#

Zenko: "you can't, Oni-chan promised me that he'd never fight infront of me!". She said with a serious face. "so no more fighting."

Izuku: "huh?"

Zenko: "the fight's over!"

Izuku stood up from his stance as he began to speak.

Izuku: "and why the hell should i have to follow your family rules?"

Zenko: "NO MORE!"

Izuku stayed silent for a few seconds as tension filled the atmosphere until he raised his hand to which he scratched the back of his head.

Izuku: "oh yeah... i just remembered i had something to do. I don't have time to waste on you idiots."

Metal bat got up: "you're the one who attacked me!"

Izuku: "Guess you get to live a little longer, metal bat."

Metal bat: "what...?!"

Zenko: "Oni-chan! Let's hurry up and go home! There's a giant monster too"

Metal bat: "oh, right! The executives are in danger. I have to hurry."

He began to walk as zenko hung on his leg trying to pull him back.

Zenko: "Wait, you're joking, right?! Come on! don't do this! You're gonna die!"

Metal bat: "you go on home".

Zenko: "Ugh! You big idiot!"

Zenko tries pulling him back due to his severe wounds and then lightly slaps him on the head; this minor, powerless slap is strong enough to cause the hero to collapse from his wounds and his petered fighting spirit.

Zenko: "Huh? Oni-chan? Hello?"

Meanwhile

Izuku was walking through the road while 2 monsters were watching him from a roof of a building.

Peonix man: "so that's the hero hunter everyone's talking about. Not bad for a human."

Sludge villain: "he's a coward for not finishing him off."

Peonix man: "no, that guy may actually prove himself useful sludge."

He looked at his side only to see him gone. He looked down to see where he was and he came out from the sewer spying on metal bat and his sister.

Sludge villain: "hey, that's metal bat's little sister. The more hostages, the better."

Izuku: "Hey."

The sludge villain was smashed like a bug by Izuku.

Izuku: "so you're the creepy gaze I was sensing.

The villain quickly fixed himself and Pheonix man flied down and landed behind Izuku.

Izuku: "it's still alive?!"

Pheonix man: "wait hero hunter!"

Izuku: "two against one huh?" he said with a smirk

Pheonix man: "we are not your enemies. Take a look at this." he stuck his hand out of his costume to show Izuku a card. "I'm sure it will interest you?"

Izuku: "monster association?"

Pheonix man POV: "he took the bait."

Pheonix man: "follow me. I'll take you to our lair."

To his Suprise Izuku ripped the paper and threw it on the ground.

Izuku: "I'm not interested. Get lost."

Pheonix man chuckled as he began to fly.

Pheonix man: "I'll pretended I didn't see that. But we'll be meeting again." he was in the sky now. "As long as you keep hunting heroes, that is."

Sludge villain: "just you wait!"

he said as he entered the sewer and left. Izuku was silent for a few seconds until he spoke.

Izuku: "disgusting."

he said as he began to walk away. What he didn't know was that, someone with green hair was watching from a far distance.

Tatsumaki (sighs in disappointment): "what happened to you Izuku."

Meanwhile

Do-S: "oh? Even more suiters to become my slaves? HOW TITILLATING!"

She prepares to whip the heroes, but before the whip can make contact, it is suddenly stopped midair.

Fubuki: "Really? That's all it takes to be aa threat level demon? Not a bad wager. If i defeat you their minds will be freed, yes? Then they'll be in my debt, like killing two birds with one stone."

Do-S: "Ara Ara... I wish you wouldn't toy with my sadistic instinct. I don't wanna kill you too quickly.

After a few hours of fight fubuki is at a disadvantage and is losing slowly until tatsumaki shows up and you know the rest. She beats up do-S, yada yada yada, Do-s runs off an stuff. (can't be asked to get into detail)

Tatsumaki: "you okay?"

Fubuki: "y-yeah... thanks for the back up."

Tatsumaki: "listen... i saw Izuku..."

Fubuki: "what! Is he alright?!"

Tatsumaki: "he is the hero hunter everyone's been talking about... I saw him fighting metal bat and Mirko. He was ruthless."

Fubuki: "and you didn't do anything?!"

Tatsumaki: "he's our nephew what do you want me to do?! Just kill him?!"

Fubuki: "I— y-you... *sighs* what do we do now?"

Tatsumaki: "we'll ask that bastard and inko what happened first... then we'll figure out the rest."

Fubuki: "alright let's go".

Meanwhile
Gran-Torino: "I see... so he was your best disciple... I'm truly sorry what happened Bang."

Bang: "It wasn't his fault that he became this way..."

Bomb: "bang... are you okay?"

Bang: "I'm fine..." he said as he wiped his small tear.

Gran-torino: "we'll get him back... you know... ever since those two were born... they practically saw me as they're grandpa. It was a really touching moment. Then i didn't see them after the age of 8 since they moved to Mustafa. It broke my hurt to see my little grandkids to leave."

Bang: "I see... I was more like a father figure for him than his own father... heck... I was a better father than his own dad. When I saw him going on a rampage, it broke my hurt."

Bomb: "alright save your chats for later old guys... let's continue our search".

Gran-Torino: "you're older than us you know..." he said with a smirk.

Bang: "let's go."
After a long day of the monster raid throughout Japan, it all calmed down as the monsters retreated to their lair. The news was filled with how the monsters took out a lot of heroes during the raid. Right now, the teachers of UA were talking in the meeting room.

Nezu: "with the connection between the hero killer Stain, the monster association and the league of villains, it's possible criminals and monsters everywhere will become much bolder".

Snipe: "it'd be best if we could start preparin' for that before it happens. As a school we should be takin' every precaution. If fights against villains and monsters are gonna continue, then havin' kids train against robots ain't a practical."

Aizawa: "don't forget about the hero hunter too... he's also a problem too. Any info about him?"

Midnight: "not much... he hunted 70 heroes in the past 2 months, 2 of them are S-class heroes, and 15 of them were Pro heroes. They either quit their job as a hero or are out of commission for a few months at least."

All might: "..."

Cementoss: "there is a possible chance that he might come for the students here... are we planning anything to deal with him?"

13: "we could try to find out his real identity for starters".

Present mic: "we could go to the forest camp to train the students for real combat... that way, they're ready for anything at that point. We could also bring more staff in case the same thing happened at USJ happens there."

Nezu: "I was planning on doing that too. Very well, after the students done their exams, both 1-a and 1-b can go to the forest camp. Also, I have contacted the wild wild pussy cats to help us train the students. You are all dismissed."

With that everyone else left the room and Aizawa went towards his office to check something.

Aizawa POV: "hmm... now where is that file?" he said as he was looking through a bunch of folders. "Ah ha... found it! Now let's see... alright this is the list that contains the names that have participated during the entrance exam. Where is the green haired kid. He was accepted to UA, with that crazy score he got. What happened to him. What was his name?" he was now looking at the document which had Izuku's registration in there.

Aizawa POV: "he's all might's kid... and Izumi Yagi's brother. Guessing they're twins. How is he not in UA... something doesn't add up."
