Izuku and Aoyama had met, Aoyama playing the role of a spy to trick All For One into letting his gaurd down so Izuku and the other pro heroes could take him from surprise

Aoyama:.... is fake crying at Izuku I'm sorry but.....I will never betray my friends, uncle!! he said as he turned around and shot his naval laser at All For One

Izuku: Now! he said as the pro heroes suddenly came through warp gates made from Monoma copying Kurogiri's Quirk

Endeavor: This ends now!!

Mirko: Heck yeah!!

Class 1-A, Best Jeanist, Edgeshot, Lemillion, Suneater, Nejire-Chan, Fatgum, Hawks and other pro heroes emerge from the Warp Gates

AFO: You brat.... he then looks at all of the heroes and chuckles, using his Teleporting Goo Quirk to bring the League of Villains and Metal Liberation army members I'll leave them to you he said as he quickly escaped through a portal

Endeavor: Damn coward!!
