You have to give Electro credit, it takes some big wavos to go out in public with a mask like his, even if you are a supervillain.
Maxwell Dillon had dreams of becoming an electrical engineer (wow what aspiration) but not wanting him to be angry if he failed, his mom convinced him he was not intelligent enough, and Max reluctantly took a job as a lineman for an electric company. While he was repairing a power line, he was zapped by lightning and transformed into a living electrical capacitor. Electro was born.
Electro quickly turned to crime. One of his first heists was to rob the Daily Bugle Building stealing from Jameson's safe right in front of him. Jameson accused Spider-Man of being an alternate identity of Electro (that makes a lot of sense), prompting Spider-Man to prove the publisher wrong. Spider-Man eventually used a fire hose to short-circuit Electro.
After a number of defeats, Electro tried to take over New York City's power supply in an attempt at glory and respect. Spider-Man thwarted this plan and convinced Electro to quit his criminal career. But of course, retirement was just temporary. Eventually, The Rose agreed to fund an experimental technique that would amplify Electro's abilities, in exchange for Electro's services as an enforcer. Seeing this as a chance to rise above the string of failures that had made up so much of his life, Electro underwent the procedure. Electro attempted to demonstrate his newly amplified powers to the world, once again attempting to take control of New York City's power supply. Wearing an insulated suit, Spider-Man stopped him. Electro, in an effort to make a final grand gesture, Electro threw himself into the Hudson River while his body was highly charged, seemingly killing himself in an explosion.... but he survived. Still he tries to gain respect, but Electro just isn't that smart.
