Jellal Fernandes (ジェラール・フェルナンデス Jerāru Ferunandesu?) is a major recurring antagonist-turned-ally in Fairy Tail, introduced under the alias Siegrain (ジークレイン Jīkurein?). Hiro Mashima based his appearance on Sieg Hart, a character from his earlier work Rave Master, as a form of fan service.[19] He is registered as one of the Ten Wizard Saints with mastery over "heavenly body" magic (天体魔法 tentai mahō?), which allows him to fly, increase his physical speed, and produce energy-based weapons. He is Erza's childhood friend, and a former slave forced to build the Tower of Heaven, a construct intended to resurrect Zeref. He was brainwashed by Ultear (disguised as Zeref) into taking over construction of the tower, betraying Erza in the process. To activate the tower's R-System (the spell designed to resurrect Zeref) Jellal creates a magical projection of himself named Siegrain to act as a member of the Magic Council and manipulate the other council members into firing the magic weapon Etherion at the tower (in the anime adaptation, "Siegrain" passes himself off as Jellal's twin brother). He is assisted by his and Erza's other friends and fellow slaves, who Jellal had tricked into thinking that Erza had betrayed them. He is ultimately defeated and seemingly killed by Natsu, but is later found alive by Oración Seis and resuscitated by Wendy to help Oración Seis find the destructive spell Nirvana. However, he awakens with amnesia and, upon learning of his past actions from Erza, atones by helping the protagonists destroy Nirvana instead. During the battle, Jellal gradually regains his memories of Natsu and Erza, and rekindles his friendship with Erza. After Oración Seis is defeated, Jellal is arrested by the reformed Magic Council for his previous crimes. He is voiced by Daisuke Namikawa in Japanese and Robert McCollum in English.
