Demonic Megiddo

The Demonic Meggido is one of Dracula's most powerful spells, and makes common appearances in the Castlevania series. It is a giant explosion, varying in color.

Portrait of Ruin
Not mentioned, but Dracula will preform an attack very similar to the Demonic Meggido during the final battle. He will turn Death into a sycth and slam him on the ground, creating a powerful explosion.

Order of Ecclesia
Dracula will do this move in his battle with Shanoa. If the player manages to inflict 9999 damage to Dracula, a short cutscence will play, and Dracula prepares to unleash the Meggido. If the player does not use Dominus in the amount of time, Dracula uses the Meggido, which is unstoppable. If the player uses Dominus though, Dracula dies.

Judgement
Dracula's "Super Finshing Move." Dracula floats in the air, and will shoot a huge fireball at the opponent. The fireball then explodes, inflicting massive damage.
