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.
