Konami Lady is the female counterpart to Konami Man and one of Konami's most renowned mascots. She has not appeared in any Castlevania games to date, but is present in some crossover games and other media that include Castlevania characters.
Background
Konami Lady is an android created by Dr. Cinnamon from the TwinBee series. She appears as a playable character in Konami Wai Wai World, where her main form of attack is by performing kicks. This style of fighting is similar to Maria's kicks in the Sega Saturn version of Castlevania: Symphony of the Night.
Laura, an enemy first introduced in Castlevania: Rondo of Blood, at one point during her battle sheds off the long dress she wears and reveals an apparel underneath that strikingly resembles that of Konami Lady, consisting on a black leotard complete with long boots, and featuring a pair of cat-like ears that make for Konami Lady's wing ornaments on her head.
Konami Lady also appears as a professor at St. Gradius Academy in Otomedius Excellent, and fights the students as a boss in the training stage.
In Konami's Wai Wai World Game Book, she sets off to Dracula's Castle to rescue Simon Belmont.
