i think the dark eldar would be the hardest for tyranids to beat - for all my tyranid knowledge i havn't read anything about them being able to access the webway. but as mentioned, when everything's been eaten the dark eldar will have nothing left to sustain them - the same issue the chaos gods face.

necrons don't provide organic biomass, but all complex life requires metals - we all need zinc, iron, potassium etc - and given the complexity of tyranid life it's safe to assume they require a larger variety of metals. since necrodermis is a living metal i see no reason why tyranids would be unable to consume it, but, while logical, this is only a theory as i havn't read anything about tyranids consuming necrons, but nor have i read anything that says they can't.

tyranids are drawn onwards by the presence of biomass, but since daemons have no biomass i doubt the forces of chaos could draw tyranids towards the eye of terror - tyranids don't even register the presence of daemons unless attacked - if it's not food then it's not important. the gods' minions, while numerically plentiful, are of a finite supply though - each aligned daemon is a fragment of its god, and each god is fueled by sentient emotions, so each time tyranids wipe out a sentient species the gods will then have less power within themselves to subdivide into created daemons, meaning the longer tyranids keep munching the weaker the gods will get.

and while the shape of the nightmare to come is awesome fanfiction, and i particularly love the 'tyranorks', i also question the validity of that occuring: tyranids are the most advanced species in the galaxy in terms of evolutionary adaptation/survival, and anyhing that the ork genome can offer tyranids already have.
