Elexis is a seductive femme fatale type with raven-black hair and green eyes. As described as "PC Zone", Elexis had "clearly experimented a little too much on herself and is a self-styled Mad Genius. She wears a series of futuristic leather outfits, has a twisted sense of humour and may be bisexual." She is also shown to be a bondage fetishist. In the original "SiN" game, many of the official arts showed her portrayed as armed, including in the game's package European cover pictures, but she wields no weapons at any point in the actual game's story mode. For the game's sequel, initially titled "SIN2", at least one re-design of the character has been created and publicly revealed in 2003, but then abandoned. Elexis' ultimate new look in "SiN Episodes" was instead closely based on Bianca Beauchamp, who then served as Elexis' real-life model for publicity and trade show appearances.
