Horned Rat
The Horned Rat is the festering disgusting god of the equally disgusting Skaven race in the Warhammer Fantasy setting.
Spreader of AIDS and STIs, rolling around in his own muck, the Horned Rat only exists to troll his own worshippers and the rest of the world and to tear down civilization, the arts, anything remotely good and replace it with his own favourite pastimes (namely disease, backstabbing, and cruelly toying with others).
