Fat Man

The Fat Man is a spectre of true and disgusting evil. Believed to be the personification of Human excess, he appears as a squat, morbidly-obese man, with pasty, white skin and a wormy mouth flanked by heavy, dripping jowls. Black, piggish eyes stare out hungrily from beneath the rolls of fat on his head. To make matters worse, he’s nude and covered with stretch marks and dark blue-green veins. When the Fat Man appears, he is always feasting. He may be seated in a pile of his own excrement in a street or at the next table in a tavern. His harbinger is a rancid smell of sour milk and ham.

Also Known As: Corpulent Stalker, the Devourer, Gluttony

Attracted By: Magic of Slaanesh, Selfish Spellcasting
