Erza Scarlet (エルザ・スカーレット Eruza Sukāretto?), also known by the nickname "Fairy Queen, Titania" (妖精女王(ティターニア) Titānia?), is a 19-year-old S-Class wizard, a high-ranked wizard who is usually tasked with performing extremely dangerous missions, and the most powerful female member of the guild. Her name was derived from Eru, a character from the one-shot manga created by Hiro Mashima that served as a pilot for Fairy Tail.[13] She specializes in a form of magic called "the Knight" (騎士(ザ・ナイト) Za Naito?), which allows her to immediately summon and equip different swords, armor, and clothing from hammerspace at will using a magic ability called "requipping". She also has an artificial right eye, which replaces the one she lost as a child while forced to build the Tower of Heaven, and grants her immunity from illusions and other magical effects that occur through eye contact. She acts as Fairy Tail's disciplinarian and does not hesitate to punish anyone who disregards the rules of her guild, for which she is feared by her fellow guildmates. However, she is not without compassion towards her friends, and becomes more open to their antics as the series progresses. She is a childhood friend of Jellal Fernandes, another child slave from the Tower of Heaven, who later betrayed her after being brainwashed into becoming a servant of Zeref. Despite Jellal's betrayal, Erza is shown to have feelings for him, and eventually forgives him after he develops amnesia and shows remorse for his actions. She is voiced by Sayaka Ohara in Japanese and Colleen Clinkenbeard in English.
