Erza Knightwalker

Erza Knightwalker is part of the Edolas Kingdom and is the Royal Army Captain of the 2nd Magic War Division. She is the Edolas counterpart of Erza Scarlet.

Appearance
Knightwalker is a well-endowed female with long, flowing, wavy scarlet hair with an elegant, loosely tied knot at the back, but it was later reduced into a short bob haircut in an attempt to have her troops distinguish her from her Earth Land counterpart, Erza Scarlet.

Knightwalker wears a very provocative outfit comprising of a revealing, halter-type armor breastplate top, that leaves much of her cleavage and stomach exposed, with light-armored gauntlets and greaves on her forearms and forelegs, respectively, as well as her thighs. She also wears a dark bikini bottom with a piece of cloth obscuring her hips. A dark scarf could be seen wound around her neck.

Personality
Unlike her Earth Land counterpart, Erza from Edolas is sadistic, cruel and would kill with a smile. Knightwalker shows no sympathies towards her enemies and kills without mercy. She had been involved in killing over half of the members of Edolas Fairy Tail, thus, earning her epithet. She seems to take great pride of this title bestowed upon her; as a result, she took it as a personal insult when Lucy told her that her Earth Land counterpart, Scarlet, happens to be a staunch ally of the Earth Land Fairy Tail Guild, whose loyalty to her friends was also unquestionable. This led to her becoming more hostile than she already was towards Lucy, and even opted to kill her by dropping her from a great height.

Knightwalker also appears to value her pride as a Captain for the Royal Army, and Carla making her prostrate herself by kneeling down to the floor seemed to be a real blow to her ego that when Pantherlily informed her of Happy and Carla's rebel status (and that was made even worse by the fact that Carla wheedled information from her only mere moments ago regarding the location of Natsu and Wendy through trickery by claiming to be the daughter of Shagotte), the latter became the first whom she targeted to kill. However, her streak of fighting has made her overly arrogant and she doesn't seem to take losing lightly as seen when Erza Scarlet managed to temporarily beat her off screen.

Edolas arc
Erza Knightwalker is the Fairy Hunter in Edolas, set to destroy the Edolas Fairy Tail. In a mission to capture and exterminate the Edolas Fairy Tail members, Erza fails since the guild is able to teleport away. Erza is then surprised to see the 4th Army Captain, Sugarboy, arrive at the scene. After he comments that the guild moves very quickly, Sugarboy informs Erza that, since the Anima Plan succeeded, all the Army Captains are to return to the Royal City. Sugarboy also informs Erza that the Earth Land Mages and Magnolia townspeople are turned into a giant lacrima. Erza smiles after hearing the news, knowing that the Magic in Edolas will be stable for a while.

Erza and Sugarboy then return to the Capital and admire the giant lacrima with the 3rd Army Captain, Hughes. As the three walk, talking about the Magical Power and the lives of the people within it, they meet up with the Royal Army's Chief of Staff, Byro. Byro complains to Erza, pointing out that she still haven't captured and eliminated the remaining Mage guild in Edolas, Fairy Tail. Hughes and Sugarboy defend Erza just as the 1st Army Captain, Pantherlily arrive. After telling Hughes and Byro to be quiet, Pantherlily leaves. Erza, commenting on Pantherlily's moody attitude, tells the others that he isn't pleased about the captains' competition to see who destroys the rebels first.

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

Erza later arrives at Lucy's cell to execute her. Lucy 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. Although initially surprised, Erza ignores this comment and begins to drag Lucy by her hair, telling her not to confuse her with her Earth Land counterpart. Lucy tries to get her to let her go and help her save her friends, saying that Erza is not the type of person who would laugh at someone's suffering. Erza ignores her again and suspends her over a balcony, telling her that she likes to look at other's suffering, and that is why she is titled 'Fairy Hunter', as she has killed dozens of members of Fairy Tail. After saying goodbye, Erza lets Lucy fall from the balcony, luckily, Lucy is saved by Carla and Happy at the last moment. Carla 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 almost succeeds. However, the rest of the royal guard arrives, and Pantherlily informs Erza that Carla and Happy are the "fallen" (traitors). All three then attempt to escape, leaving Erza, who is extremely angry for being deceived. Happy and the others are soon cornered by the Imperial Guards of Extalia and the Royal Army of Edolas. Among them are the Army Captains, including an extremely angry Erza.

When Faust activated Code ETD, Erza notices Carla, Happy, and Lucy use the confusion as a way to escape. Thinking that the three are heading towards the West Tower's Basement, Erza commands her forces to go after them and fortify the defenses.

Just as Lucy, Carla and Happy are running down the stairs, Erza arrives and throws her spear at them, causing an explosion that stops them in their tracks. Erza then goes up to Carla and is about to kill her but Happy stands up and shields in the middle of the two. Erza merely smirks and decides to kill Happy first when, preceded by an explosion, her Earth Land counterpart, Erza Scarlet and Gray Fullbuster arrive. Seeing her soldiers fall to Gray's Ice Magic, Knightwalker quickly evades his attack and tries to strike him, only to be stopped by her Earth Land counterpart, resulting in each Erza inflicting a minor scar on each other's faces; Knightwalker wiped off some of the blood coming from her scar, then smeared it across her left cheek in acknowledgement of Scarlet's power, noting that she did not expect herself to be in the way of her duties, much less an equal in fighting skill. With that, the two Erzas introduced themselves and begin their battle while the other Fairy Tail Mages leave to find Natsu and Wendy. The Fairy Hunter first used Silfarion to battle with speed, but is quickly matched by Titania's Flight Armor, much to Knightwalker's surprise. Knightwalker then uses Mel Force to blow a strong tornado to stop Scarlet, and quickly follows with Explosion to end the battle, but Scarlet negates the damage using her Flame Empress Armor, shocking Knigthwalker once more. Erza Knightwalker then comments on Erza Scarlet's ability to change both armor and weapon, and reveals that she can change her weapon too, enabling her to increase her battle strength physically. With that, Knightwalker proudly states that she will reveal the true powers of the spear, the both of them prepares for another round.

Despite wielding her spear, Knightwalker is eventually defeated and her armor was taken away by Erza Scarlet, who disguised as her in order to gain access to the control room. However, even though she is laden with injuries, she still managed to vault over the control room walls and release Faust from Erza Scarlet. Reaching her anger limit, she is then seen staring daggers at her counterpart as Team Natsu rides Coco's Legion to the Lacrima Island. She cuts her hair off to shoulder length in order to distinguish herself from her counterpart, and orders the Raizo Squad to chase after them. After the lacrima is sent back to Earth Land and everyone rejoices, Knightwalker makes an untimely appearance. Equipped with a new armor and a cannon-like weapon, she blasts a hole through Pantherlily, claiming that the battle is not over yet.

As the Royal Army chases after the Exceed, Erza Knightwalker waits for and ambushes Lucy, Gray, Erza Scarlet, and Coco. When she saw that her counterpart is coming after her, Knightwalker tells her squad to land down, and she will take care of Scarlet herself. The both of them then declare that there are no rooms for two Erzas, and one must perish.

The two continue to fight, evenly matched, to which Knightwalker pulls out her strongest weapon, Ravelt, and Scarlet her strongest armor, Armadura Fairy. With their strongest assets now at their disposal, the two charge at one another and strike, but only end up destroying their spear and armor respectfully, using up the last of their Magic power and causing the floating island they're on to fall. Knightwalker refuses to give up the fight though resort to using her fist turning the fight into a brawl on the falling rock. All the while, she argues that the whole Anima plan is necessary to revive their world. But Scarlet disagrees, showing that they're still fighting despite no powers, and people won't just die because there's no Magic. They have the strength to continue on and all things, living or otherwise, have a voice. These words get through to Knightwalker, who realizes Scarlet's right. The two soon hit the ground in a crater; both are alive but weakened and cannot move. Knightwalker acknowledges her loss and concedes to Scarlet, but Scarlet asks if there is such a thing as winning or losing since they are, after all, the same Erza. With Knightwalker and Scarlet having made peace, Anima begins to take Scarlet back to Earth Land. The two Erzas bid one final farewell in happiness.

Manga to Anime Differences

 * Due to censorship, in the anime, Knighwalker's armor was copied by Erza Scarlet, while in the manga, it's stolen, leaving Erza Knightwalker wearing only a cloth.
 * After Knightwalker's initial clash with Scarlet, they both gained a scratch on their face. In the manga, the scratch bled, and Knightwalker used her own blood to paint two stripes on her left cheek. Though they both got a scratch on their face in the anime, it didn't bleed, most likely due to censorship.
