chaos warriors were very similar in stats to black orks in fantasy, and those were the biggest, toughest, most elite orks until the Ironjaws were introduced.
In fourth ed, a chaos warrior basically had the stat line of an Empire general, as that was what they were, the pinnacle of human martial prowess. Their increased stats through being champions/lords etc came from patronage of the chaos gods. They made black orcs look like goblins.
