Boku no Hero Academia the Movie 4: You're Next

Japan remains unstable after the war that shook hero society, and Deku and the rest of Class 1-A patrol the country helping civilians and confronting villains wherever order has collapsed. Into that vacuum steps a powerful man who adopts All Might’s image and the words “You’re next,” twisting the former Symbol of Peace into something centered entirely on himself. He calls this new identity Dark Might.

Backed by the criminal Gollini Family and an ability capable of reshaping the battlefield around him, Dark Might forces Deku, Bakugo, Todoroki, and their classmates to face someone wearing the face of the hero who inspired them. Defeating him requires more than overpowering an imitation; they must prove that All Might’s legacy was never just a smile and overwhelming strength that anyone could copy.
