Erza Knightwalker

Erza Knightwalker is the secondary antagonist in the Edolas arc of the anime/manga series Fairy Tail. She is part of the Edolas Kingdom and is the Royal Army Captain of the 2nd Magic War Division and the Edolas counterpart of Erza Scarlet. This version of Erza is a very sadistic and callous person, having earned the epithet the 'Fairy Hunter' for hunting down the Edolas Fairy Tail Guild for ages. She ultimately clashes with her Earth-Land self in an intense battle that ultimately results that ultimately resulted in the former's defeat. After this, Knightwalker showed genuine remorse for her actions and became more kind.

She is voiced by Sayaka Ohara in the Japanese version of the anime and Colleen Clinkenbeard in the English version.
