Alicia cheated on Carl Grissom with his enforcer, Jack Napier. After Grissom learned that Jack had been seeing Alicia behind his back, he sent his right hand man on a mission that had been set up to have him killed by Lt. Max Eckhardt. Napier survived, but fell in a vat of chemicals that drastically mutated his cell structure, and freed him to become as monstrous as he desired. After Jack Napier had reinvented himself as The Joker, , he killed Carl Grissom and returned home. When Alicia returned and saw his clown-like appearance, she fainted on the floor. The Joker then scarred her face with sulphuric acid, and made her wear a porcelain mask. Days later, Joker presented the mask to photojournalist Vicki Vale, and informed her that Alicia threw herself out a window.
