Sharon is Slayer's wife, and apparently immortal and invincible; for one thing, she can survive getting drained of blood by Slayer without any apparent lasting effects (one of Slayer's opening scenes before a battle shows him completely draining her). In one of Eddie's endings, Eddie melts after attempting to possess her, and I-No (who set him up to this) comments, "Illness, parasites... Nothing sticks to her." Sharon's exact nature remains unknown. Her name is almost certainly a reference to Sharon Osbourne, the wife of Ozzy Osbourne, also known by fans and the media as the "Prince of Darkness" (a title typically attributed to vampires in various media).
- Sharon does not appear to talk or make any sort of sound in any title.
