Jellal Fernandes (ジェラール・フェルナンデス Jerāru Ferunandesu) is a childhood friend of Erza Scarlet. Before he lost his own memory, he was a Dark Mage who desperately sought to revive Zeref via the R-System. Jellal served as the main antagonist of the Tower of Heaven arc and is currently a member of Crime Sorcière.

Jellal is a young man whose most prominent features are his blue hair and a red tattoo under and above his right eye, which he has had since his childhood. As his Siegrain alter-ego, he dressed himself in elegant yet simple robes; consisting of a long white tunic with black stripes across the edges and on the upper part of the arms, a decorated collar, large straps connected to decorated buckles closing the inducement on the front over a dark shirt, and matching pants and shoes. He also sported a ring on his right middle finger, and usually had the medallion attesting his status as one of the Ten Wizard Saints around his neck, hidden by his jacket’s collar.
