SupaStarAshAnd no doubt the Dominion. I can't see the Klingons, Romulans, Breen and Cardassians being a pushover either.
We have seen both Klingon, Romulan and Cardassian drones.
the hivemind changes the specs probably constantly, and klingons rommies arent going to win even not the feds if the borg comes in full power!!
Well after Endgame, I just cant see it. That and it just wouldnt happen, that and if the Borg surrvied Endgame (which I doubt) the Federation have nice shiny new tecnology from the Future designed to combat the Borg. Endgame put an End to Borg plots. (If you think about all the serries and movies have been tied up).
