Who wins?
By entire, I mean EVERYTHING. Halo, for example, would have all of the Precursors, Forerunners, Covenant, Flood, and Humans all teamed up against ALL the Star Wars universe
They all have their technology as well. Halo has their Halo Rings and such, Star Wars has all their Star Destroyers and Death Stars and all that

A Halo could kill everything in the universe. The death star would just be a hollow hull by the time it was finished. In other words, you should have said "Halo Ring vs. entire Star Wars and halo universe" The answer- Halo Ring always gets the last laugh
