He is voiced and mo-capped by Josh Keaton.
Born in Endicott, New York, Max Dillon was involved in an unspecified accident which granted him the ability to absorb electricity and deploy it in destructive blasts of energy, along with other assorted abilities. After becoming a super-criminal under the name Electro, Dillon encountered the masked vigilante Spider-Man, being the first villain with actual superpowers the wall-crawler ever fought. The two had many encounters over the years, with Spider-Man impeding Max's quest to become pure energy. Max was incarcerated in the Raft sometime around Spider-Man's eight year tenure.
After escaping from The Raft, Electro leads Spider-Man on a chase, luring him into a trap where he was ambushed and brutally beaten by the Sinister Six. With Spider-Man apparently out of the picture, Electro moved to attack the police department, holding the officers at bay until Spider-Man arrived. Once Spider-Man arrived, healed from his injuries, Electro flew off.
Later, Doctor Octopus uses Electro as a back-up plan after his attempt to kill Spider-Man with a bomb failed. Vulture brought Spider-Man to Electro and together the two took on the superhero in an aerial battle. Eventually, Spider-Man was able to fight them both off and webbed Electro for the police to find him.
Electro is one of the most carefree, destructive, and chaotic of Spider-Man's foes. He even takes part in bantering back and fourth with Spider-Man mid-fights. He is also thrill-seeking and enjoys getting a rush from danger. He can also be very homicidal, as it is noted that he has killed several cops over the course of his criminal activity. Despite his hot-headed nature, he seemed to get along well with Vulture, unlike Rhino and Scorpion.

- interestingly enough, Electro's voice actor, Josh Keaton, voiced Peter Parker/Spider-Man in the animated series Spectacular Spider-Man.
