Izumi:GET THE HELL AWAY FROM HIM!!!!
The 2 shouted as they got close to Shigaraki, Korugiri opens a portal between them the thinking that they will be teleported away they could easily dodge it but, suddenly two hands grabbed both of there faces shocking Shigaraki and All might then the owner of the hands who grabbed the 2 students came out he had black hair his whole left arm is made of metal as the figure slams both of them to the ground flat on there back

He shouted but he couldn't move because his time is up as he watched the figure let go of her daughter and looks at shigaraki.
Shigaraki:You, what are you doing here??!!
???:You have been called
It that moment Shigaraki knew who he was talking about he couldn't argue with him
Shigaraki:Damn it, well there's no point of arguing Kur-
BANG BANG
A loud bang was heard it was a gun shot and shigaraki was shot in the legs making him fall and followed by another gun shot but Kurogiri covered Shigaraki as the figure looks to where it came from and saw Snipe with the other heroes snipe then points his gun at mysterious figure as he shoots the figure then blocks all the shots using his metal arm making Snipe look in shock
???:Korugiri take him back to base and return to pick me up I'll cover you
Korugiri:Understood
He said as the figure then summons an AR-15 Grenade launcher and started firing at the heroes who are at the stairs as Kurogiri wraps himself and Shigaraki out of the place leaving him behind as he starts shooting as heroes takes cover while All might is being supported by his wife and Izumi and Bakugou were out cold as Kirishima and Katsumi took them before he notice them once he was out of ammo he reloads before switches to his grenade launcher and fires at the stairs making anyone near at it take cover before reloading and fires near to where All might, Inko, and the other students but suddenly a huge Ice blocks and looks to where its coming from
Shoto:I don't think so
As the figure was about to fire Kurogiri appeared behind him and creates a small portal for him he summons 5 smoke grenades and throws it making the area around him filled with smoke and no one can see Mic used his quirk to dispel the smoke away but they were already gone causing enough damage not to only All Might but to the 2 students Izumi and Katsuki.
A few moments police finally arrived and arrested all of the villains as the UA staff will be having a meeting of a sudden attack and talk about who are these people that just attack the school.
