Zeref

Zeref Dragneel is a prominent character in the manga and anime series Fairy Tail. He is known as the "Black Wizard" and is considered the most powerful and evil wizard in the history of the Fairy Tail world. Zeref is the older brother of Natsu Dragneel, the protagonist of the series. He is responsible for the creation of various demons, including the Etherious demons, who make up the strongest forces within his army, Tartaros. Zeref's primary goal throughout much of the series is to find a way to bring about his own death, as he is cursed with immortality and an unending existence filled with sorrow and regret. He also seeks to revive his deceased brother Natsu, who died in a dragon attack years prior. Zeref's immense power stems from his mastery of black magic, a forbidden and destructive form of sorcery. His long life has allowed him to accumulate vast knowledge and develop incredibly potent spells, making him a formidable antagonist. Despite his evil reputation and destructive actions, Zeref's character is complex, driven by a deep sense of loss and a desire for peace, even if his methods are morally questionable. His presence in the story significantly impacts the lives of the Fairy Tail guild members and the fate of the entire world.
