they do indeed have utterly devastating weaponry and if their cloaking tech is as good as you say then the only race that could openly oppose them, i think, would be the necrons whose tech is surely advanced enough to see through/nullify yautja cloaking.

as for space prowess, their ships have the same cloaking tech which would again give them an advantage unmatchable by anyone except maybe necrons.

and as for any alliances, yautja have no interest in other races except for hunting purposes, but based on the avp novels they may ally, very grudgingly, if tyranids were a threat to the existance of their own race.
