Harmony of Dissonance
The Sumerian king of the wind demons, Pazuzu can be found in Dracula's throne room in Castlevania: Harmony of Dissonance as a surprise boss. It appears by hatching from a giant egg in the background, where Dracula's throne should be. Pazuzu attacks mainly by leaping, spewing fireballs in waves, and summoning hordes of tiny devils, which are not worth any experience, to attack you. The best way to fight Pazuzu is to stay underneath the two raised platforms in the room so that Pazuzu will jump on top of them above you, thus allowing you to attack him and dodge most of his attacks.
