Alice May

Alice is generally manipulative with boys she's supposed to like, such as her prom date Randy, and Fred Jones, which she hides behind a sweet and caring facade. She was shown to be cunning and very good at hiding, even telling Freddy that she prefers to walk, so she can work on her plans secretly without his notice. Alice May was an agent of Mr. E, being ordered to take on the disguises of the Ghost Girl and later the Obliteratrix, when dealing with Mystery Incorporated. "Alice May" is likely just an alias, with her true name and backstory remaining a mystery.
