How do Tyranids and Chaos space marines React to eachother?

Question

I have played Warhammer 40k for two years. And i have been wanting to find out the same question ever since i fully understood the story of Warhammer. Chaos and Tyranids are two races that are known to be mortal enemies to the Imperium of man. But i rarely see artwork of them fighting eachother. I know a few things like, Eldar have been long enemies of Necrons, Tau find Tyranids a threat to their Empire, The Inquisition are extremely hostile to chaos. But what i want to know is How do Chaos and Tyranids find eachother as or something. If you know what i mean of course.

Answer 1

Well, the Chaos Legions are the first Space Marines.  Most are around 10,000 years old (since the Horus Heresy).  Chaos hate the xeno filth as much as the loyalist marines do, nothing has changed that.  Also, serving the Dark Gods makes us superior to ANY alien scum, whether it be Tyranid, Tau, or Eldar.  When you deal with daemons, and live agelessly in the Warp, Tyranids aren't really too scary.
