From the depths of the netherworld is Infernity Archifend. The master of a variety of evil magics, Infernity Archfiend is always giddy to test out what sort of reaction normal people will have to hellfire infused magics. He's someone who finds a great level of amusement in tormenting others, both in benign ways like taunting them, and by subjecting them to the most intense hellfire imaginable.

Archfiend is a character I have a very specific parallel for in my mind. To me Christopher Guerrero's take on Gecko Moria from One Piece is exactly what I imagine Archfiend to sound like. His voice should be high pitched yet scratchy, constantly on the verge of a wicked laugh. He takes a great amount of pleasure in harming others, so the more wicked his voice and especailly laughter the better. The third line is again, meant to be called out like a fighting game attack, see the description of the project for the sort of direction that entails.
