Biography
While Maxwell Dillon, an electrical engineer and lineman, was repairing a power line, a freak lightning accident caused a mutagenic change that transformed him into a living electrical capacitor. His powers were initially weak, so he spent some time stealing electrical equipment from Stark Industries to charge himself. Soon taking the name Electro, he turned to a life of a professional criminal, his first victim being J. Jonah Jameson. Electro broke into the Daily Bugle Building and stole from Jameson's safe right in front of him. Jameson accused Spider-Man of being an alternate identity of Electro, prompting Spider-Man to prove the publisher wrong. During his confrontation with Electro, Spider-Man was nearly killed when he touched the electrically charged supervillain, but was only knocked out. Spider-Man eventually used a fire hose to short-circuit Electro while wearing rubber gloves to protect himself. Since their first confrontation, Electro has become one of Spider-Man's recurring and most powerful enemies and has even joined the Anti-Spider-Man Team, the Sinister Six.
