One of the main antagonists in the f.e.a.r. series. She alternates between playfully toying with the protagonist and attempting rend the flesh from his bones. She is commonly shown in two forms: a young girl with a red dress, which is how she is shown in the first-game, and as a young adult with pale skin and burn marks in the second-game.
One of the final reveals in the game is that she is the daughter of Harlan Wade - the scientist who conducted research on her - and the mother of the protagonist of the first game.
