Dianne Grayton was a wealthy and beautiful young woman who grew bored and decided to become "the most horrible dispenser of justice of all times." She started disguising herself as a classic Halloween witch and using her spiders to scare and punish villains. Her power is to control black widow spiders. She is also athletic and a skilled fighter. She became romantically involved with Raven (Quality) when he saved her from German agents, and she formed a crime fighting team with him. Also, Phantom Lady teamed up with Spider Widow and the Raven on several occasions even though Spider Widow feared that Phantom Lady was a rival for Raven's affections. Her enemies included the Spider Man.
