Nids like crunchy stuff... But basically, your asking IG vs Nids who would win .... and we all know, you only field IG when you like to loose. Since, The Empire == IG , I say nids take it leaving behind only the crunchy undigestables.
What about the power to completely exterminate a galaxy of all life? How does that compare to the power of the force?
