Orgodemir

"I am Orgodemir, king of all beings and ruler of the heavens! I shall carve my name in your bodies as a grim reminder of the ephemeral insignificance of mortalkind!"

- Orgodemir

Orgodemir is the main antagonist of Dragon Quest VII for Playstation and its 3DS remake. He's the demon lord that sealed all lands from existence, except for the only landmass in the world, Estard. He has many forms, in the final battle he goes through four of them. The blue dragon-like one is its true form and the one that he's most associated with because it's also how he looks like  its other appearances, but since he's always caring about beauty he tends to go around disguising as a dashing dandy.
