This mug is shaped like a bust of the evil Marvel Comics villain, DR DOOM, chief foe of the Fantastic Four, and despotic ruler of Latveria.

Doom is a genius scientist as well, but also dabbles in dark magic, sometimes combining both.

He wears riveted metal armor and a mask of his own design which he never removes, along with a green hooded cloak.

From MONDO:

"Mondo Tikis brings the doom ... Victor Von, that is. Be the toast of Latveria with a DOCTOR DOOM Tiki Mug, cast in stoneware ceramic and finished with a lustrous multi-color glaze. Manufactured by our pals at Tiki Farm."

Variants of this mug design include a chrome "Metal Face" and a 4-Color version as well.
