Anguilla, one of the 12 Deadlords, in her appearance from Fire Emblem Awakening.

Technically, it's the generic female Risen Dark Knight, but (at least in the main game) Anguilla's the only one to use this design, so it might as well he hers. Also used some concept art to give her a helmetless design.
