Remember the Master Death's Surrogate, on my piece "On Death's behalf..."? (thumbnail downwards) > Well, he just got promoted! Tired of being laughed at, and because he did such a great job (against all odds), Master Death released him of her personal guard duty and assigned him new functions on the "esticó-pernil"* enterprise.
His new powers are nothing short of a god-demon. He instills serious and persistent doubts on people's minds, oh, the irony!), preparing their souls to Hell. When they're corrupted enough, he collects them to join in the under mob. The skull is a soul container, by the way.
Now that he's riding the mustang of thought, he is now a shape-shifter. I think I'll draw him on new shapes from time to time...
* translation "Esticó-pernil" comes from the portuguese saying "esticar o pernil", meaning "To Die". Literal translation would be something like "Stretch the Legs", or "Stretch the Shank".
