At the Cybernetic Inc training room we see Y/n, Armor Knight and Aristo training together as they fought training androids as they fight side by side. Armor Knight fire hid engery beams at the androids before one try to swing at him but he dodges as he leaps backwards and land on his feet.

He uses his booster legs and came up and kick the android in the chin, sending it flying and finishing it off with a engery blast.

We cut to Artsto swing his sword as he cut down the androids and using his shield to block their attack as he continues cutting them down while Y/n flies around and shooting all the androids with his shooting stars and crash onto the ground with a shock blast.

He slowly gets up as the training ends and they leave the training room and walk down the hallway.

Aristo: Ah it feels good training along side youse.

Armor knight: I can say the same. Your not bad yourself.

Aristo: Thank you. You have no idea how many battles I have fought on my planet.

Armor Knight: Must be some battle.

Y/n: So what you guys wanna do?

Armor Knight: Figure to get something to eat. Anyone fancy with some fish food.

Aristo: Yes I would like the taste of human foods.

Y/n: (smile) I'm down. Let's go and-

Suddenly alarms goes off and the trio were called to Genji at the command room so they race over and we see Genji in the room looking at a large monitor with the news as the trio arrived and see the news of the same Brian like monsters attacking Hosu City.

Armor Knight: Are those the same monsters that Y/n fought?

Genji: Yes and the same that attack the UA training hall along side with the villains.

Aristo: What are these beast?

Genji: We believe they are called Nomu although we have no idea what they are. But there is a lot of them.

They see heroes arriving on the scene to help out the citizens while battling the Nomu's but they seem to not stand a chance.

Y/n: They need back up.

Genji: Indeed. I suppose your new team is ready for combat?

Y/n turns to Aristo and Armor Knight which they are ready and then Y/n turns back to Genji and said.

Y/n: Yeah. We're ready.

Genji: (smile) That's I like to hear. A cargo Helicopter is ready for you three. Good luck and be carful.

They node and they leave the room and head out while Genji maintain things in the command room as he watch the chaos happening at the city.

(Later)

We see a cargo helicopter flying over Hosu City as the drop door open and the trio looks down to see the destruction.

Y/n: Okay let's do this.

Armor Knight: Well see you two down there.

He leaps off the helicopter and flies down with his boosters while Aristo came up and turn to Y/n.

Aristo: I feel like he is showing off.

Y/n: (smile) That's his style.

Aristo: Can't argue with that.

Aristo leaps off and then Y/n leaps off as all three decent to the city. We then cut to a few police officers firing at a large hulk like Nomu as it flips over cars and let's out a roar. Suddenly Y/n came down and lands a punch at Nomu directly to his brain and crushes him with a powerful blow.

The other officers is shocked to see Y/n here as he stood up and sees more of them coming. Then Aristo came crashing down, crushing most of the Nomu's and then pull out his hammer and swings it hitting a group of them while Armor Knight hover above Y/n and launching missiles and blowing up the rest.

Armor Knight: Looks like there is a lot of them. Where are they coming from?

Y/n: It doesn't matter. Right now we need to focus on helping out the heroes snd civilians.

Armor Knight: Right I'll strategists with the police and heroes.

Aristo: I'll help the officers to evacuate the civilians.

Y/n: Right and I'll help out the heroes and save some lives. Let's get to work guys.

The three of them split off to do their own thing all awhile Kurogiri and Tenko watches this on the top of a tower.

Tenko: Looks like the alien boy is here and it seems he has new friends.

Kurogiri: Indeed he has. Let's just see how strong his new friends maybe.

We cut to a squad of officers evacuation the civilians as they cross the bridge. Then suddenly they hear roars in front of them and sees more hulking Nomu's charging towards them. They begin to open fire but their bullets have no effect.

They were doomed when Aristo rams all two of them into a wall and stomps them with his foot. He sees more coming so he pulled out his sword on his second hand and charge foward and begins cutting them up while smashing them with his other hand as he begins to battle all Nomu's while this gives the civilians a chance to evaluate.

We cut to Armor Knight talking to the officers and other pro heroes of his strategy attack and ways to defeat the Nomu's which they listed. We cut to Y/n flying over the city and taking out any Nomu until he sees flames shooting out as he flies over and sees Endeavor fighting some Nomu's on his own as he is burning them away.

One was about to jump at him until Y/n blasted him with his cosmic beam as Endeavor noticed him.

Endeavor: Oh....its you.

Y/n: Your welcome.

Endeavor: I would have dealt with it myself.

Y/n just doesn't say anything and noticed more behind him so he turn and uses his gravity powers and throws them to out of space which doesn't impress Endeavor as he turn and burns more of them from behind.

Y/n: What's the situation?

Endeavor: Right now these things is giving us hell. Pro heroes are getting injured by those things and bullets doesn't seem to harm them. This must be a work of the villains.

Y/n: Could be although I wouldn't make sense to send it a large pack on a city unless they wanted to test them for combat.

Endeavor: Possibly.

The two gone silent as Y/n begins to take off but before he leaves Endeavor ask him.

Endeavor: Find Shoto. I was with him and when the attack start he headed off just to save lives. If you do come across him......help him.

Y/n:........I will. But I'm not doing this for you. I'm doing this because if he is out there and maybe in trouble.....I will help him.

He then flies off as Endeavor just walks off.

(Sometime later)

We see Y/n flying through the city and soon he lands on the tallest building and looks down and seeing the destruction below him. He then to shut his eyes and listened. He can hear explosions, screams and gunfire as he keeps listening for a moment until he hears something that sounded familiar.

Y/n: (thought) Izuku.

He then disappeared from the roof with super speeds as we cut to Izuku and Tenya paralysed and laying on the floor by Stain as he places the tip of his blade onto Tenya cheek and says.

Stain: Your finished. So long.

He rasied his blade and was ready to strike at him but suddenly Y/n appeared out of nowhere for them and punches Stain in the face. The impact was so hard it make a blast that sent Stain flying and land hard onto thr ground.

Izuku: Y/n?

Y/n: You two okay?

Izuku: Yeah.

He turn to Tenya and he stare at Y/n for a bit and then node. Y/n turn to Stain as he slowly gets up and smiled.

Stain: (smile) We meet again alien boy.

Y/n: I won't let you kill my friends Stain. Fight me all you want.

Tenya: No don't! I won't let you end up just like my brother!

Y/n: What?

Stain: Ah yes. Before I met you I took care of his brother and he was really easy to take out.

Y/n: So your the villain that hurt his brother. Your going down Stain.

Stain: (smirk) So your going to fight me alone?

???: Not alone.

Then Shoto came up next to Y/n as he turn to see Shoto standing next to him. Shoto then turn to Y/n and node. Y/n smiled and node back as the two turn to Stain while Stain ready his blade and then he charges towards them.

Shoto created a ice wall in front of Stain while Y/n punch it. Shattering it into pieces as they hit Stain and then Y/n grabs him by the leg and throws him to the ground.

Before he could Shoto rushes over and throws a fire punch at Stain and sending him flying out of the alleyway and onto the street. He crashes into a building but climbs out and gete mad. Shoto came out of the alleyway so Stain charges towards him but Y/n appears in front of him and strikes a kick at him.

This sent him flying up into the air and then he pulled him down with his gravity which he crashes onto the ground hard. Stain struggles to move so he throws knives at Y/n shoch he moves which he let's him go and Stain changes towards him but Shoto punches him with a ice punch and he was frozen when he hits the ground.

The two land on their feet and at first they got him but suddenly be breaks free and dashes over and lands a cut at Shoto. With Shoto's blood on his blade he was about to lick it when suddenly Tenya speed over and punches Stain.

He loses his blade as Izuku came over and strike at kick at him towards Y/n which he lands a punch in the face and he sent rolling across the road.

All four heroes stood there as Stain slowly gets up and glares at the four.

Y/n: Your done Stain.

Stain: Done Huh? Youse are not even worthy of being heroes and I'll be the one to judge that. Mark my words alien hero.......you will die by my hands so I suggest you watch your ba-

Suddenly he gets shocked and drop to the ground as Armor Knight appears behind him as he said.

Armor Knight: What a freak.

Izuku: I guess it's over?

Y/n: Yeah looks like it.

He walks over to Stain and sees that he is unconscious. He then looks over just to see a warp portal disappear from sight meaning the villains were here and they were watching the chaos. The Nomu threat became to an end as the officers and some pro heroes take the unconscious Stain  to prison as they loaded him up into a prison truck as Y/n watch Stain go maybe for good this time as he turn and rejoin his friends with the other pro heroes.

The city is saved however soon the villains will return and cost even more destruction.
