(Intro)

Aizawa: Who are they?

Thirteen: How can those two Humagears transform?

Hikari: We don't know. But right now, we need to put a stop on those Humagears, bring them alive, and get more info from them about the hacked Humagears.

Y/N: Hikari's got a point! This can be our only chance to find out who's controlling the Humagears!

Okami: It's about damn time we put up a fight to these damn Humagears and Villains!

(Down with the Villains and Rogue Humagears)

??????: Where is he...? And I went through the trouble of bringing this whole crowd, too... All Might... The Symbol of Peace... I can't believe he's not here. I wonder if he'll come if we kill some kids?

Jin walks up to him.

Jin: Kill is always the best option for our new friends with us, Tomura! 

Horobi: I say we take our time having... "fun" with the kids.

Tomura: ... You really are insane, Jin, Horobi.

(Back with the Students)

Kirishima: What? Villains and Rogue Humagears? No way... There's no way they could get into a hero school!

Yaoyorozu: Sensei, what about the trespasser sensors?

Thirteen: We have them, of course, but...

Todoroki: Did they only appear here or around the whole school? Either way, if the sensors are not responding, that means they have someone with a Quirk that can do that. An isolated area separated from the main campus during a time when class is supposed to be here. They might be fools, but they're not dumb. This surprise attack was carefully planned with some sort of goal in mind.

Hikari: It's too well planned out. I bet none of them are the masterminds behind the plan.

Y/N: I'll say.

Aizawa: Thirteen, start the evacuation. Try calling the school and A.I.M.S. These Villains and Humagears even had something to counteract the sensors. It's possible someone with radio-wave-type powers is interfering.

Aizawa turns to Kaminari.

Aizawa: Kaminari, try contacting the school with your Quirk, too.

Kaminari: Yes, sir!

Midoriya: What about you, sir? Will you fight by yourself? With that many, even if you erase their Quirks... Eraser Head's fighting style is capturing after erasing the enemy's Quirk.

Aizawa: A frontal battle is... You can't be a hero with just one trick. I'm leaving it to you, Thirteen.

Thirteen nods and Aizawa jumps down towards the villains.

As Aizawa was fighting the villains and Humagears, Y/N, Okami, Hikari, and Midoriya were surprised at the battle.

Y/N: Aizawa-sensei...

Okami: I can do better than that.

Iida: This is no time for analysis!

All four of them look to see Iida and Yaoyorozu.

Yaoyorozu: Hurry up and let's get out of here!

Y/N: Oh! R-Right!

After a big of running towards the door, a purple fog appeared in front of the door.

Purple Fog: I won't let you, Nice to meet you. We are the League of Villains. It may be presumptuous of us, but we have invited ourselves and Metsuboujinrai.net into the home of heroes, U.A High School, in order to have All Might, the symbol of peace, take his last breath.

Midoriya: Huh?

Y/N/Okami/Hikari: Metsuboujinrai.net...?

Hikari: So they're the ones who hacked and took control of the Humagears.

Purple Fog: I believe All Might should have been here. Has there been some kind of change? Well, that is neither here nor there. This is the part I am to play.

Okami, Bakugo, and Kirishima run at the Purple Fog ready to land an attack.

Okami: YOU BASTARD!!!

Okami pulls out his ShotRiser and shoots at the Purple Fog. As Okami's blue energy bullets hit the Purple Fog, they blow up along with Bakugo using his Explosion along with it.

Kirishima: Did you consider that you'd get beaten by us before you did it?

Purple Fog: Oh dear, that's dangerous. That's right. Even if you are students, you are excellent golden eggs.

Thirteen: No! Move away, you three!

Purple Fog: My job is to scatter you all and torture you to death!

The Purple Fog scatters around everyone and covers them in Purple Fog.

Kirishima: What the...?!

Hikari: What is this?!

Asui: Ribbit...

(Mountain Zone)

(Y/N/Okami)

Y/N: WHAT THE HELL IS THIS?!!!

Y/N and Okami were teleported in the air and begin to fall to the ground.

Okami: FUUUUUU--!!!!!

Y/N and Okami then hit the ground really hard.

Y/N: Ouch.

Y/N and Okami look up to see Yaoyorozu, Jiro, and Kaminari already fighting the Villains and Magias.

One of the Villains sees Y/N and Okami.

Villain 1: Over there! They're vulnerable! Get them!

Magia: R-R-Report of a-a-a-a-l-lost chi-i-i-d!

All of the Villains and Magias run at Y/N and Okami getting up from their fall.

Yaoyorozu: Y/N!!!

Jiro: Fuwa!

Kaminari: Watch out!

Y/N and Okami immediately pull out their drivers and put it around their waists.

ZERO-ONE DRIVER!

SHOTRISER!

Okami bent back and dodges an incoming swing attack from the Magia, at the same time, Okami takes out his Shooting Wolf Key and activates it.

BULLET!

Okami then inserts the Shooting Wolf Key in his ShotRiser.

AUTHORISE!

KAMEN RIDER. KAMEN RIDER

Okami: Henshin!

SHOTRISE!

Y/N dodges an attack from a Villain by sidestepping as he pulls out his Rising Hopper Key and activates it.

JUMP!

Y/N jumps back and scans his Rising Hopper Key in his driver.

AUTHORISE!

Y/N: Henshin!

PROGRISE!

TO-BIA GA RISE! RISING HOPPER! ( A jump to the sky turns to a rider kick.)

https://youtu.be/QUbIL9UNO0I

SHOOTING WOLF! (The elevation increases as the bullet is fired.)

https://youtu.be/9_6dVKaeRQg

Villain 1: No way! Kamen Riders?!!

Villain 2: They're here too?!!

Villain 3: It can't be!!

Villain 1: But they won't stand a chance against all of us along with our magias!

Zero-One and Vulcan group up with Yaoyorozu, Jiro, and Kaminari.

Kaminari ducks from an attack and starts running away.

Kaminari: Scary! Seriously, did you see that just now? I saw the River Styx, seriously! What the heck is up with these guys? What's going on?!

Jiro: Worry about that later. Right now, we need to figure out how we'll get away from all these people and these Humagears.

Kaminari: Then give me a weapon, too!

Jiro: You're the electric guy, aren't you? Hurry up and take care of them!

Vulcan: Wait... She has a point! You have a powerful Quirk, you know! Just get your ass up and help us, you dumbass!

Kaminari: I'm not a dumbass! You saw during the combat training, didn't you? We were paired up! I can only cover myself with electricity! I can discharge electricity, but it's not like I can control it! I'll hit you four, too! It's like, you know, the same as Todoroki! Even if we wanted to call for help, there's interference jammin' the signal. Listen, you four. Right now, you can't count on me. I'm counting on you!

Zero-One: Kaminari, this is no time to be fooling around! 

Jiro: You're a guy, aren't you? Stop whining.

Kaminari dodges a magia.

Vulcan/Jiro: Then, we'll just use you as a human stun gun!

Both Vulcan and Jiro kick Kaminari at a magia.

Kaminari: Seriously? Idiots--

Kaminari touches the magia and begins to shock it.

Magia: E-E-Error-ror-Error-Err-!!

Kaminari: Oh, it's working. I'm strong. You four can count on me!

Jiro: Hey, you're too happy-go-lucky.

Zero-One: Wait a second... That gives me an idea! *looks at Jiro* Jiro, Vulcan, buy me some time for a few seconds!

Vulcan: Roger!

Jiro: Got it!

Zero-One: Momo!

Zero-One runs up to Yaoyoyorozu and whispers his plan in her ear, Yaoyorozu was surprised by this well thought out plan, she nodded and started making what Zero-One asked for.

Zero-One pulls out a Freezing Bear key and activates it.

BLIZZARD!

AUTHORISE!

PROGRISE!

ATTENTION FREEZE! FREEZING BEAR! (Fierce breath as cold as arctic winds.)

Villain 2: Stop messing around, kid!

Jiro inserts her earphone jack into her boot speaker and sends an explosively loud heartbeat soundwave towards the Villain.

Jiro: Kaminari, you should've requested something to help you aim in your costume order!

Vulcan: That's what I just said!

Yaoyorozu: Y/N! It's done!

Vulcan/Jiro: Huh?

Yaoyorozu: It takes some time...

A huge sheet comes out of Yaoyorozu's back and covers her, Jiro, and Vulcan.

Yaoyorozu: ... to create something big!

Villain 3: A sheet?

Villain 4: Is it supposed to be a shield?

The magias were confused.

Yaoyorozu: It's an insulation sheet 100 millimeters thick. Kaminari, Y/N.

Zero-One: Heh. You ready to discharge, Kaminari?

Kaminari smirks.

Kaminari: I see.

Kaminari prepares a big attack as Zero-One freezes the ground full of ice and froze all of the villains and magias in place.

Zero-One: All right! Kaminari, do it now!

Kaminari: In the case, I can be really strong!

Kaminari discharges a huge amount of lighting that covers the whole mountain zome towards all the villains and magias, frying them.

Kaminari: Yay...

Zero-One looked at Kaminari who had a ridiculous look on his face.

Zero-One: Pfft!!! HAHAHAHAHAHA!!! W-What's with that face?! That's hilarious, Kaminari! AHAHAHAHAHAHAHA!!!

Zero-One looks over to Yaoyorozu and Jiro kicking Vulcan out of the sheet.

Vulcan: Oww! What the hell was that for?!

Zero-One: Are you guys oka--

Yaoyorozu: KYAA!!! D-Don't look over here, Y/N!!!

Zero-One: S-Sorry!!!

Zero-One quickly turns back because he almost saw Yaoyorozu's breasts fully exposed.

Zero-One: Phew... That was a close one... But... Momo's breasts... They're so big... Yeah... So big... She really has grown for the past eight years...

(Short Timeskip)

After Yaoyorozu made a new hero suit for herself, both her and Jiro got out of the sheet.

Yaoyorozu was still embarrassed because she saw Y/N almost looking at her breasts and she tried to face him.

Yaoyorozu: G-Great idea, Y/N. 

Zero-One: It wouldn't have been possible if you weren't here.

Jiro: What do we do now--

Zero-One: WHOAAA!!!

Vulcan: LET US GO, YOU DAMN MAGIA!!!

Jiro was interrupted by Jin flying towards them and carrying Zero-One and Vulcan away from the group with his wings.

Yaoyorozu: Y/N!!!

Jiro: FUWA!!!
