Problem: The movie addresses the asteroid in a previous scene (hits Carmen's battleship, disables communication) and this chud will pick up on that immediately. While I like your idea generally, in this specific case this dudebro will have an obvious counter.
That's why I mentioned WH40k. There's no sci-fantasy setting save for WH40k where a starfaring civilization could even destroy a city that's halfway across the galaxy without using what present civilizations of that setting considers ancient for-all-intents-and-purposes-magic (eg Forerunners, Xel'Naga, Protheans, Celestials). It doesn't matter if it's Star Wars, Star Trek, Starcraft, Halo, Mass Effect, Dune, and so on. WH40k could get away with it through warp shenanigans as in the civilization shoots the rock through a warp rift and have the rock appear on the another side of the galaxy to strike the city.
