月光騎士
Echo appeared in the fourth "Moon Knight" series, saving Marc Spector from a strip club in L.A., where she worked undercover under the guise of a stripper. But when saving Moon Knight, her cover was blown. Moon Knight later proposed that they join forces against the West Coast Kingpin, and invites her to dinner. Moon Knight is obviously attracted to Echo and it is suggested that Echo feels the same, despite punching Moon Knight in the face for kissing her. When she meets up with Moon Knight, they get attacked by the Night Shift. Although Echo and Moon Knight beat them, the police arrive, and attempt to apprehend the duo as well. Echo was killed by Count Nefaria, the man trying to be the new West Coast Kingpin.
