Bloodthirster
From Warhammer - The Old World - Lexicanum
Bloodthirsters, the Greater Daemons of Khorne (other names given to them in background are Blooded Ones, Lords of Skulls, High-handed Slayers and War Given Form). Of all the Daemons, they bear the greatest resemblance to stereotypical demons, having a human body, cloven hooves instead of feet, leathery bat-like wings and horned dogs-heads. They are armed with a fiery whip and a massive two-headed battleaxe. They are the most warlike and aggressive of all Daemons.
