One day another lineman got in trouble and Dillon agreed to save him, but only after the coworker would expressly remark to the electric company about Dillon's heroism, which would auger well for his chances of getting promoted. However, a freak lightning storm hit and caused the lineman in distress to lose his balance and fall to his death. In the process Max Dillon gained super powers when he was struck by lightning while in contact with power lines still connected to their spool. The unusually configured magnetic field generated by the wound spool of cable and live, high-tension wires induced a body-wide mutagenic change to his nervous system. Dillon found himself transformed into a living electrical capacitor, powered by the micro-fine rhythmic muscle contractions that normally regulate body temperature. Generally, Dillon's criminal actions were governed by his selfish love of money. Adopting the gaudy garb of a so-called super-villain, the deranged Dillon sought to use his newfound power for personal gain. Electro's first and most frequent nemesis was the wisecracking, web-slinging super hero known as Spider-Man. The Daily Bugle publisher J. Jonah Jameson was convinced that Spider-Man and Electro were the same man, until Spidey defeated Electro by wearing rubber gloves and shoes. He next battled Daredevil when he attempted to break in the Baxter Building, headquarters of the Fantastic Four.
