YMMV / Black Clover: Elf Reincarnation Arc

• Complete Monster: Zagred, the Word Devil, long ago swayed the humans of the Clover Kingdom into siphoning the elves' magic reserves, before exterminating the entire race himself in a way that would hold the prince accountable and trying to possess their leader Licht to destroy the human world, forcing Licht to turn himself into a Demon. Defeated, Zagred reincarnated the elves with a dark spell, letting one elf named Patry lead the terrorist Eye of the Midnight Sun to do as much damage as possible and revive the others to destroy humanity. Revealing himself, Zagred gloats about all he has done to the world before trying to manifest fully, then tortures Patry, breaking him spiritually to transform him into a mindless dark elf and gleefully has him attempt to wipe out the heroes. After stealing Patry's Four-Leaf Clover Grimoire and transforming it into a Five-Leaf Clover Grimoire to obtain more power, Zagred proceeds to open a doorway to pure darkness, seeking to consume the human and elven races alike.
