Annihilation Wave hits DC
To me it always seemed like space in DC was always emptier. Marvel has three huge consolidate empires (Kree, Skrull, and Shiar) while DC, to my knowledge, doesn't. SUre there's planets like Apocalypse, THanagar, and whatever who can somehow affect stuf on other galaxies, but nothing so coordinated that could occupy a galaxy.
So, lets say annihilus attacks the DC from a point halfway from Oa to the edge of the universe, so that it has to pass Oa in order to get to earth. Lets say this is now DC universe if there was no Blackest Night going on. Not that there aren't other color lantern corps, just no Black Lanterns runing around eating hearts.
How does the DC universe fare? Assume Earth is the last planet Annihilus wants to conquer, cause we have main characters powers. Does Earth survive the last attack. Lets assume the monitors or other extra dimensional entities that wouldn't want to see the multiverse collapse don't intervene in our favor.
Alternatively, how would current real world Washington DC fare if the A-wave were dropped on it?
