[Warhammer 40K] I remember reading somewhere that the Tyranids are immune from Chaos. Is this true? If so, does this unsettle Chaos? Also, how about the Necrons?

First of all Necrons have fuck you levels of power, the only reason you aren't being fucked over by them is because it's like literally the last thing on most of their to do lists.

Tyranids are an extra galactic force that are basically a big grey area in the Warp. Whatever energies they may release don't contribute to it. Chaos is concerned because if the Nids eat everyone they starve. But at the same time the Nids also avoid major warp storms and the Eye of Terror like the plague, probably because there is absolutely nothing for them there.
