Electro

"'Don't you know? I'm Electro!'"Max Dillon, better known as Electro, is a character from Marvel Comics and the primary antagonist of The Amazing Spider-Man 2.

Early Life
Max Dillon was an individual who was virtually unknown to everyone he met, and held plenty of anger as a result. He got a job as an electrical engineer at Oscorp and helped design a power grid for their power plant, but was never credited. One day, Max was rescued by Spider-Man, and was surprised when Spider-Man called him by name and claimed that Max was his eyes and ears. Max soon developed an obsession with Spider-Man.

On his birthday, Max was ordered by Alistair Smythe to check out a faulty power cable. Though he found the cable and tried to plug it in, it shocked him and caused him to fall into a pit full of electric eels. The eels bit him and imbued him with electrokinetic powers, thus transforming him into Electro.

Max is first seen in Oscorp working on a power cable. He gets shocked offscreen, but since the engineers closed the electric eel pit to prevent anyone from falling in, Max breaks his body.

Electro is then seen bouncing Spider-Man around Tesla coils to the tune of "The Itsy-Bitsy Spider." Spider-Man recommends that Electro take up dubstep, which he gladly does.

During the credits, Electro celebrates his birthday at the Villain Pub, and his dubstep album becomes a success.

Electro joins the other Marvel antagonists as they bet on who Thanos will kill in Infinity War. When Lord Voldemort bets that Spider-Man will be among the casualties, Electro claims that Thanos cannot kill off Spider-Man, but Vulture insists that Thanos can, which Thanos backs up.
