The Chaos Gods are incorporeal beings with no physical bodies that can devastate far more worlds than Valkorion can. Slaanesh with its birth turned thousands of lightyears of spacetime (and all the star systems in this span of space) into the Eye of Terror, the largest Warp Rift (a place where the Warp coexists with real space) in the galaxy. Slaanesh's birth also entailed it devouring the souls of the majority of the Eldar race, and at this time the Eldar were the largest empire in the galaxy, with the most amount of individuals of their race save the Orks. Countless trillions of Eldar died.
That is all great.Now how he is supposed to fight Valkorion who is a disembodied entity that can completely conceal its presence from Jed and/or Sith, manipulate time, devastate worlds and siphon energy of both living beings and spirits?
All I see there is physical stuff.
This is one of the Chaos Gods that banded together with the other four to kill the Emperor in the Horus Heresy, because they feared the Emperor, and he was already using his psychic power to destroy their realms in the Warp.
