Mystogan , whose real name is Jellal, is a former S-Class Mage of Fairy Tail and the current King of Edolas. He was also considered the most mysterious member of the guild, as he did not show himself, or his face, at all. He is the Edolas counterpart of Jellal Fernandes.

Being the Edolas counterpart of Jellal Fernandes, Mystogan possesses the same dark eyes, blue hair and tattoo on the right side of his face. He wears a dark blue cloak and his arms and legs are mostly covered in bandages. During his time with Fairy Tail, he wore a dark blue bandana with a silver forehead protector, and a green mask that obscured the bottom half of his face to hide his identity from his guildmates. During the series, however, the design of his mask appears to change frequently. He usually carries his Magic Staves on his back, which are held by a dark green strap going across his main body.
