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

Well the elites can glass every planet, if that doesn't work the flood can infect every biological thing basically, if THAT doesn't work the halo rings could kill every sentient being, if even that doesn't work then master chief would solo the entire star wars universe, or I'm sure the forerunners or precursers could probably manipulate time some how to stop the star wars universe from existing
