Gharnef

Gharnef (called Garnef in the Japanese version) is a Bishop from Fire Emblem: Ankoku Ryū to Hikari no Tsurugi and Fire Emblem: Monshō no Nazo. He was once a star pupil of Gato. He was once a man of justice, but lacks a caring heart, which causes him to be disqualified to become the inheritor of the Aura spell. Out of jealousy, Gharnef invented the spell Maph and it twisted his soul, trying to destroy the world with the help of the Dolua Empire. He attacked Altia to kidnap Ellis, so he can use her resurrection spell to revive Medeus. However, Marth defeated him and slays Medeus, but Gharnef wasn't quite dead yet as he hid his soul in the Dark orb.

When he heard about Hardin's sorrow, Gharnef disguised himself as a merchant and offered him the Dark Orb, which twisted his soul. He then gathered four noble sisters, Rena, Maria, Nina and Ellis, to be sacrificed for Medeus' revival. A member of Marth's army eventually killed him once again with the Starlight spell and thwarted his plan.

Gharnef's Maph spell makes him invincible to attacks, however a magician using the spell Starlight(ironically created by his former master) can kill him.
