Legend is a mysterious character. Almost nothing is known about her. She talks very little, and doesn't say much. She's quick, efficient, and merciless. Cold, and calculating. And cruel and remorseless.
Legend wields the same abilities as the Avatar. No one, not even Aang, can figure out how this is possible.
Role in UltimaEdit
In Ultima, it is eventually revealed that Legend is actually a corrupted version of Aang's next succesor, Korra, having been changed into a monster by Padro Lodo to swell up the ranks of the Org. Once Aang discovers the truth about Legend, he decides to make it his mission to free the next would be avatar from Lodo's clutches and survive her deadly assault against him in the process.
