"Morrigan Aensland (モリガン・アーンスランド, Morigan Ānsurando) is a video game character from the Darkstalkers series of fighting games developed by Capcom. She is voiced by Yayoi Jinguji in many of her video game appearances.
Morrigan is a succubus who is very vain and lives for little more than the excitement of battle. She appears as a beautiful woman with long, light green hair, large breasts and bat-like wings on her back and the sides of her head. Morrigan can reshape these wings into spikes and blades when attacking her enemies, as well as using them to shield herself from enemy attacks. Her wings can also separate from her, and form into a cloud of bats. She uses a variety of magical attacks as well.
While Demitri officially fills the role, it has often been suggested and implied that Morrigan is the main character of the Darkstalkers series, due to her importance in the overall story as well as her many appearances outside of her game series. She may even be considered a protagonistic anti-hero, because despite her demonic appearance and nature, she is not evil."
