Lore

From the moment Cho'Gath first emerged into the harsh light of Runeterra's sun, the beast was driven by the most pure and insatiable hunger. A perfect expression of the Void's desire to consume all life, Cho'Gath's complex biology quickly converts matter into new bodily growth—increasing its muscle mass and density, or hardening its outer carapace like organic diamond. When growing larger does not suit the Void-spawn's needs, it vomits out the excess material as razor-sharp spines, leaving prey skewered and ready to feast upon later.
