i forgot about chaos...

so necrons have the best technology to damage the tyranids - namely the celestial orrery. but chaos has the best troops to combat tyranids - daemons - because when they 'die' they leave literally no bio-mass as they are simply tangible energy.

the problem facing chaos though is the 'shadow in the warp': tyranids have no emotional effect on the warp, but the hive-mind does have a presence in the warp - the shadow in the warp - which has a muffling effect on psychic powers. as the tyranid race continues to wake up the power of the hive-mind is also waking up and the 'shadow in the warp' grows in tandem with the waking process. now this is just a theory but i think if the hive-mind reaches a state of fully 'awake' (when the vast majority of tyranids have awakened) then the shadow in the warp will have grown so potent that it could potentially have a suffocating effect on the gods themselves.

even if the necrons managed to wipe out all bio-mass then the tyranids still win, because the galaxy would be effectively destroyed and the tyranids would just move on to the next. and they wouldn't have a sense of victory, but then they don't have a sense of victory even when they chomp through a galaxy - they just have a sense of continuing.

tyranids are entering the galaxy at multiple locations which could indicate that they're coming from multiple galaxies, but it's very unlikely as it would mean that they left a multitude of galaxies, all heading here, and they got here at the same time (relatively speaking). it's more probable that the multiple entries are just the same uber-fleet that are encircling the galaxy (although given that no-one knows the extent of the hive-mind it could very well be that it co-ordinated different galactic branches of tyranids to converge on the milky way. but as no-one knows one way or the other then the denizens of the milky way better hope it's a single fleet!).

the main problem is that while every race has 'this or that' which would be useful against tyranids, no single race can oppose them on their own - they are simply too vast and too adaptable. i refer to the previous codex quote - "...that unless every race unites in opposition, it will destroy all life, all civilisation."
