Loki

Original : Loki
Japanese : ロキ ( Roki )
English : Loke

Loke , named after the Norse god Loki, is a flirtatious wizard regularly accompanied by young women. Using a ring called Regulus, Loke can conjure light-based magic attacks. His true identity is the celestial spirit Leo, who is initially owned by Karen Lilica. After preventing her from summoning other spirits to keep her from bullying his fellow celestial spirit Aries, Loke inadvertently leaves Karen defenseless while on a mission which results in her death at the hands of Angel. Exiled from the spirit world, Loke distances himself from any celestial wizards he encounters. Three years later, Loke's magic power weakens severely until his body slowly begins to fade away. After Lucy Heartfilia discovers his identity as a spirit, she saves his life and restores his former power by persuading the Celestial Spirit King to reconsider Loke's exile, which allows him to return to the spirit world. Despite becoming one of Lucy's contracted spirit partners, Loke is still considered a member of Fairy Tail, and temporarily nullifies his contract with her to serve as Gray Fullbuster's partner during the S-Class exam. In the Japanese version of the series, Loke is voiced by Daisuke Kishio. In the English dub, he is voiced by Eric Vale.
