Laurie Juspeczyk / Silk Spectre II
Laurie Juspeczyk (Silk Spectre II) is the daughter of Sally Jupiter, the first Silk Spectre. Laurie's mother apparently wanted her to follow in her footsteps and so she fought crime for ten years before the Keene Act banned vigilantes. Unlike the other protagonists, Silk Spectre was not based on a particular Charlton character, although her relationship with Dr. Manhattan is similar to that between Captain Atom and the heroine Nightshade.
In the Watchmen film, she is played by Malin Åkerman.
