The high-voltage supervillain known as Electro started out as Max Dillon, an average but greedy electrical worker, who, in a freak accident, was transformed into a human generator, able to produce as much as 10,000 volts a minute. Calling himself Electro, Dillon used his powers for criminal activities, and was often confronted by Spider-Man, making them enemies. Recently, Electro was hired by an unknown villain to cause a mass breakout in all of the supervillain prisons in order to free the X-Men foe, Sauron.
