Darth Vader vs Loki
Emperor vs Thor
Luke vs Hulk
Han Solo and Chewbacca vs Star Lord and Drax
Chirut Imwe and Baze Malbus vs Daredevil and Punisher
Bobba Fett vs Captain America
Obi Wan Kenobi vs Spiderman
Kylo Ren vs Luke Cage
Rey vs Jessica Jones
As much as I love Star Wars, IMHO only Chirut and Baze and maybe Kylo Ren have a shot at winning. And Ren only does it through the force because Cage kills him otherwise.
On second thought, movie Vader can win vs MCU loki. I think he wouldnt fall for illusions, and while loki might could fight through the TK force choke and otherwise, vader would get in for the kill with the lightsaber.
But then again, thats one of the reasons I like Star Wars is it seems more "realistic" sci fi where everyone is not uber powerful.
