I love how each of the Greater Daemons of Chaos have facial expressions that emphasise what they're about.
A warrior-beast of unmatched violence. The personification of martial rage. Murder.
A jolly, generous and benevolent bringer of disease. A caring father who wants to see you become the best you can be; even after you die and you become mushroom food.
Elegant pride in all things; including killing. Joyous amazement in every new experience. Pain and pleasure are the same.
