What if in captain america 2, the final battle comes, captain is losing, he’s injured badly, probably stabbed. He’s dying and camera pans to his dying face. He’s in immense pain. But something happens, he glows dimly and suddenly captain’s gone, instead it’s Loki. Loki then gets up and kills everyone. And he disappears to a far off prison in a realm we haven’t seen before. In a cell sits Odin, in another Sif and the warriors 3, and finally captain. Captain looks up, “so earth falls to you? It will never kneel to a man like you. Earth has protectors waiting to avenge it.” And Loki smirks, “what good are Earth’s heros when they are nothing more than prisoners?” he laughs, and walks out of the prison. The camera pans to Loki’s prisoners as Loki turns back to face the camera and changes to captain once again. The credits roll.
