Revival and becoming the new Electro
It was later revealed that Francine had been cloned by the evil doctor Miles Warren, better known as the Jackal. It was not much later that Francine was rejoined by Max Dillon, Electro, whom was also her killer. It was planned for Max to recieve his powers back once more. But when the procedure to regain his powers started, nothing happened to him. That was until Max walked up to Francine. Max released electricity towards her. She became a sponge and took all the electricity in Max's body, but eventually wanted more, started kissing him and drained Max him dry, frying and killing him. Francine requested the Jackal if he could also revive Max, but Jackal has made no promises so far. She then took over the identity of Electro. Her first act was killing the hero known as the Prowler.
