The Electro Legacy

A lineman for an electric company, Maxwell Dillon was struck by lightning while working on a power line, triggering a freak mutagenic reaction that transformed him into a living electrical capacitor. Armed with the ability to generate and discharge massive amounts of electricity, he turned to crime and quickly became one of Spider-Man's most dangerous recurring foes.

Francine Frye was a young woman who became entangled with the original Electro, Max Dillon, and through that connection inherited his electrokinetic abilities — gaining the power to generate, absorb, and discharge electricity, fly via electromagnetism, and overload electrical systems as the new Electro.
