Place it at the exact moment the hero shot appears, after the build-up and before the reaction. Follow it with an And His Name Is John Cena sting for a double announcement, or end on a Yaaaay Cheer Sound when the group piles on.
About this sound
This is a nine-second Brazilian voice clip announcing "Xandão, o último herói da terra" in a dramatic, exaggerated heroic style. It feels funny and mock-epic, giving a small moment absurdly grand importance. It comes from Brazilian political memes about Alexandre de Moraes, a Supreme Federal Court minister nicknamed Xandão, framed ironically as Earth's last hero.
