Erza Knightwalker

Erza Scarlet's counterpart in Edoras was introduced riding a creature resembling a winged ox. Her counterpart's surname, "Scarlet" was replaced with "Knightwalker". Erza Knightwalker is part of the Edoras Kingdom and is a Royal Army Captain of the 2nd Magic War Division.

Personality
Unlike her Earth Land counterpart, Edoras Erza is sadistic, cruel, and would kill with a smile. Showing no sympathies towards her enemies and kills without mercy, she had been involved in killing over half of the members of Edoras Fairy Tail, thus earning the title Erza the Fairy Hunter.

Synopsis
When Natsu and co. are at the Edoras Fairy Tail, she sets out to exterminate the guild with the 4th Army Captain, Sugarboy. She and Sugarboy failed to capture Fairy Tail, because the guild managed to teleport away. The two mention that Fairy Tail cannot keep teleporting forever. They also discuss that the Anima plan worked and that the real Fairy Tail is at the Palace locked in Lacryma. Erza is a Fairy Hunter in Edoras, set to destroy the Edoras Fairy Tail.

Edoras Erza then returns to the Edoras Royal City .The Joint Chief Of Staff HQ, the 3rd Division Captain, Hughes, talks to Erza about the Lacryma, which is actually Magnolia in Earthland. Then, the Royal Chief Of Staff, Byro walks in and complains to Erza on how she always fails to capture Fairy Tail, especially since it's the only mage guild left in Edoras. Sugarboy and Hughes defend Erza, saying that she will destroy it soon. When Pantherlily, the 1st Division Captain walks in, Erza comments on how he is moody because he is unsatisfied about the situation of having a lot of magical power, even though that should have pleased him.

Later, Erza encounters Happy, Natsu, Charle, and Lucy in the secret underground pathway they were sneaking through. Erza's soliders capture everybody besides the cats believing that the cats were the ones who led the fugitives to her. Erza says "Exceed" and everybody around starts to bow, including Erza, while Charle looks shocked and disappointed, after realizing she had unknowingly helped the enemy.

Later, Erza arrives at Lucy's cell to execute her. Lucy then tries to persuade her that on Earth Land, she is a member of Fairy Tail, and is a good, responsible person to whom everyone can count on. However, Erza does not care, and tells Lucy not to confuse her with her Earth Land counterpart. Erza then suspends Lucy over a balcony, and tells her that she is fortunate, because she likes to look at the suffering of others, and that is why she is titled Fairy Hunter, as she has killed dozens of members of the Fairy Tail. She then sarcastically tells Lucy that she'll be seeing her, before throwing her off the balcony. Luckily, Lucy is saved by Charle and Happy at the last moment. Charle then tries to exploit Erza's lack of information and presents herself as the princess of Extalia, and the daughter of Queen Shagotte. She then tricks Erza into revealing the location of Natsu and Wendy, then tries to get her releasing Wendy and Natsu, which almosts succeeds. However, the rest of the royal guard arrives, and Pantherlily informs Erza that Charle and Happy are the "fallen" (traitors). All three then attempt to escape, and Erza is shown to be extremely angry about being deceived.Happy and the others soon get cornered by the Extalia and Edoras people. Among them are the Army Captains, including an extremly pissed off Erza.

After Faust defeats the Extalia with Code ETD, Erza notices Charle, Happy, and Lucy head for the west tower. She tells the guards to step up the defenses and heads for the tower. She meets them there and throws a spear at them. Stopped in their tracks, the spear lets off an attack of magic injuring the Fairy Tail members. Erza goes up to Charle ready to kill her, when Happy steps in the way. She still doesn't care, but just when she is about to strike him, Earthland Erza and Gray show up.
