Pluto (RotGotDs)

"So, Hypnos let his guard down against the humans? Yet, they die so easily. The sole splendid thing... about them is their blood's brilliance."

- Pluto to Natsu Dragneel.

Pluto, also known as the Dark Mage "Zeref", was the leader of the Dark Generals and the Spectres. Long ago, the Twelve Golden Knights of that time sealed Zeref away with the collective Golden Lights of the Twelve Zodiac Constellation, he was divided into three parts: a body that was reincarnated throughout time as a human being with the Purest Human Soul, his mind which was sealed away with his goals and the only thing capable of controlling his magic, and his ageless soul which had his stubbed magical powers.

After Seven Years, the mind of Zeref is once again being free of its seals and soon sets about events in which it can be reborn once again, freeing the Dark Generals and the Spectres from their prisons to start a new Holy War.

"Zeref" was revealed to be the 400 Year old Vessel of the God of the Underworld, hence his affinity with Death Magic, and is worshiped by a planet-wide cult of Dark Wizards who believe him to be the God of the Dead in the Rise of the God of Death series. He is fully reborn in the Return of the God of the Dead series.

Salvation from war and poverty, from the cruelty of the hands of other human, from the cruel wheel of Fate itself. After fully awakening upon coming into connection with the divine consciousness of his soul, Zeref announced himself to be Pluto, the Emperor of Darkness.
