Etzali

Etzali (エツァリ) is part of the supporting cast of Toaru Majutsu no Index.

In his only appearance in the first season of Index, he borrows the appearance of Unabara Mitsuki, the Tokiwadai Middle School principal's grandson. A certain group (the Aztec Organization) outside Academy City became aware of the growing "Kamijou Faction", so they sent him as a spy to gather information there for a month. Using Mitsuki's appearance, he attempted to become closer to Mikoto Misaka, but he ended up falling in love with her. After he loses the battle against Tōma, he makes Tōma promise to protect Mikoto and the world around her. It is later revealed that he is a member of GROUP. In Volume 19, the rest of GROUP found out that he had a senpai-kouhai relationship with the Aztec magician who was after his life in Volume 15, Xochitl. When Motoharu overheard Xochitl calling Etzali "Onii-chan", he comments that Etzali is a lucky guy, having a sister-type girl that's not related to him, and it's unthinkable for him to go and try picking up girls (referring to Etzali falling in love with Mikoto) when he already has Xochitl.

Abilities
He is a skilled magician from and former member of the Aztec Organization.


 * Appearance Borrowing: Through a magic ritual using the flayed skin of a person, he makes it into a charm which allows him to mimic the appearance of the skin's owner.


 * Spear of Tlahuizcalpantecuhtli: A replica of the spear possessed by the Aztec God of Venus and disaster which reflects the light from Venus, destroying anything the light falls upon. Since this power is classed as Godlike level, humans can't handle the original because it can kill all people in the world that are receiving the light from Venus, so the replica has flaws.

Quetzal also possesses two Aztec Grimoires, after defeating their owners in Volumes 15 and 19 and taking each off them.


 * Time related to life and death: Has the combat function of countering against any enemy that holds a weapon, having them kill themselves. It also has a very powerful defensive function, as demonstrated when it enhanced his body to withstand the bullet from "Rabbit and Moon".


 * Rabbit and Moon: Has the combat function of sniping. Uses the bones of rabbits to shoot out powerful bullets. The bones of the rabbit can be substituted by human bones, which can be purchased by obsidian and are strong enough to penetrate a shelter designed to protect against nuclear weapons.
