So this is what I get for spending time reading tvtropes and being a big fan of their Wild Mass Guessing pages.....Also, apologies if this thread has been done before. A search in the off topic forum for 'Starcraft Tzeentch' turned up no results, so I assume I'm being original by making this thread. Feel free to lock it, if I'm just rehashing some topic that was brought up years ago.
So, basically reading
TV Tropes (scroll to the bottom quarter of the page, or just
Ctrl-F 'Tzeentch'

) , I stumbled upon this theory that Starcraft and Warhammer
40k are in the same universe, just in different galaxies. More importantly the Tyranids ARE the Zerg, and what they're fleeing from if a massive Human-Protoss alliance intent on purging them from existence. The reason humans exist in two galaxies at once is because Tzeentch is a fether who likes to gak with our minds, just for the hell of it.
Now, my ideas:
a) Tzeentch or some Tzeentchian cult ARE/WERE the Xel'Naga and the whole Starcraft setting is just them having fun.
b) In the future, maybe 6th Edition
40k or Starcraft III, Blizzard and Games Workshop will put aside their feud, and collaborate to create a world where the Protoss-Human alliance catches up with the Zerg/Tyranids they're chasing, and...and I don't know. Discuss.
