Erza Knightwalker

Erza Knightwalker is an alternate-universe version of Erza Scarlet from the Edolas arc in Fairy Tail.

She is the Edolas counterpart to Earth Land's Erza Scarlet and serves as the Captain of the Royal Edolas Army (also known as the "Fairy Hunter"). In Edolas, she is feared and respected for her ruthless combat prowess and loyalty to the Edolas kingdom.

Key traits that set her apart from regular Erza:

• She has long, dark (almost black) hair instead of scarlet
• She wears a very different outfit — typically a revealing dark armor with wing motifs and a much more aggressive, militaristic design
• Personality-wise, she's colder, more sadistic, and openly enjoys battle and dominating her opponents (in contrast to Earth Land Erza's strong sense of justice and protection of friends)
• She wields a spear as her main weapon rather than relying on Requip magic (since magic works differently in Edolas)

Her most iconic moments involve her intense rivalry/fights with Earth Land Erza, where the two "Erzas" clash both physically and ideologically.

She's one of the more memorable antagonists-turned-complex character from the Edolas storyline.
