It's hero time! (Bnha x reader)

Encounter with the unknown

3rd pov

The Villains where getting out of the portal the last three where a man with hands around his body, a big creature with exposed brain and the portal itself that turn into a humanoir form

Aizawa:"The trespassing was the work of these scumbags after all, huh?" meanwhile the Shigaraki was looking around as the Villains walk foward

Shigaraki:"where is he? I went through the trouble of bringing this whole crowd, too... All Might... The Symbol of Peace.. I can't belive he's not here I wondr of he'll come if we kill some kids?"

Kirishima:"What Villains?! There's no way they could get into a hero school!"

Momo:"Sensei, What about the trespasser sensors?"

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

Shoto:"did they only appeat here or around the whole school?"

Gwen:"either way, it the sensors are not responding that means they have someone with a Quirk that can do that, an insolated area separsted from the main campus during a time when a class is supposed to be here, they might be fools but they're not dumb"

Momo:"This surprise attack was planned woth some sort of goal in mind" the redt of the class is taken back from what they just said

Aizawa:"Thirteen, Start the evacuation, Try calling the school these villains even had something to counteract the sensors, it's possible someone with radio-wave-type powers is interfering, Kaminari. you try contacting the school with your quirk"

Midoriya:"What about you, sir! will you fight by yourself?" With that many, even if you can erase their quirks, Eraser Head's fighting style is capturing after erasing the enemy's quirk, a frontal battle is.."

Aizawa:"You can't be a hero with just one trick, I'm leaving it to you, Thirteen" Aizawa jump ready to attack the Villains

Y/n:"Don't worry he's will not fight alone" He ran to the ramp following Aizawa

Thirteen:"Wait, you can't"

Gwen:"You won't be able to stop him" Y/n hit the omnitrix transforming into Swampfire

Aizawa:"What are you doing?"

Swampfire:"What it looks like" both of them ran towards the villains some of them try to use their quirks to shot at them but Aizawa earased them Y/n threw some fire balls at some villains and make some vines grow capturing others

Villain1:"Damn it its Earased Head he can erase quirks aith only see the user, but I have no Idea who the other guy is" 

Villain 2:"Are you gonna erase the quirks of heteromorphic-type villains like us, too?" he jump reafy to attack but was stopped by Swampfire punching him on the face sending him back he threw some seeds at the ground bellow him and other villains, vines grow and capture them, Aizawa use his scarf to grab some villains and threw them at others knocking them

Swampfire:"By the way you were acting I was expecting more" A villain with blade on her hands cut off Swampfire's left arm

Villain 3:"How was that"

Swampfire:"Better but not enought" he regenarate his arm before punching her, Bith Aizawa and Swampfire where able to fight the Villains without any trouble
Kurogiri saw how the other students where runing away and decide to teleport infront of them when Y/n and Aixawa try to chase after him more villains appear and block their way

Kurogiri:"Nice to meet you. We are the League of Villains, it may be presumptuous of us, but we have invited ourselves into the home of the heroes, U.A. high school, in order to have All Might, the Symbol of peace, take his last breath, I belive All Might should have been here, has there been some kind of change?"
