“The Black Wizard who lived for centuries — the origin of a tragedy built from loving humanity and hating it at the same time.”
A curse that kills living things around him against his will. Ironically, the more desperately he wants death, the more it spreads.
He can create Etherious demons. Every demon in the Book of Zeref — including Natsu — is his creation.
He has lived for centuries without aging, holding near-infinite magic reserves — one of the most powerful mages in the series.
A love-born curse that bred hatred — yet love remained inside the hatred. Centuries of isolation built a cold surface over a core of despair. He appears to want the world destroyed, but the truth is that he loves it too much to keep hurting it. His final battle with Natsu is the resolution of that contradiction.
