Spider-Man No Way Home character info: Electro

Maxwell "Max" Dillon is a former electrical engineer at Oscorp native to a parallel universe who gained the ability to manipulate electricity after a freak accident, in which he was attacked in a tank of genetically-modified electric eels. The incident transformed him into a creature of pure electricity, who later adopted the alias of Electro as he clashed with the Spider-Man of his universe, believing that the superhero did not recognize him enough. 

Dillon was found by Spider-Man when he was absorbing energy from some power cables in New York. Dillon attacked Spider-Man, who was aided at the last second by Flint Marko, who had also been transported to this universe. Sandman helped Spider-Man fight Electro by surrounding him with sand while Parker destroyed the utility poles that were feeding him energy, returning him to his normal apperance, albeit slightly different, due to the difference in energy between his universe and the new one.

POWERS 

Electricity Manipulation: Electro possesses the ability to generate bodily electrostatic energy which he can release or harness, after being electrocuted with genetically-modified Oscorp electrical eels. Electro can channel all of his body's electrical energy, and focus into any part to give out immensely powerful energy projections. Electro can generate massive quantities of electricity, theoretically up to approximately one million volts. He can employ this electrostatic energy as lightning arcs from his fingertips, and his maximum charge is more than enough to kill a normal human. 

Electrical Absorption: Electro can absorb the energy of electrical equipment such as a power plant to recharge his body's energy reserves and increase his powers further.

Flight: Electro's body was transmuted into pure electrical energy, rendering him virtually weightless and granting him the ability to glide over power lines, as well as ride on electric bolts.

Teleportation: Electro can break down his body into electricity and teleport himself anywhere.

Electrical Detection: Electro's powers grants him certain sensory and manipulative abilities. He can override systems and make electrically-powered devices obey his mental commands.

Enhanced Strength and Speed: When his body is charged to high levels, he becomes superhumanly strong and fast. 

Vulnerable to water: When Electro is fully charged, he is extremely sensitive to anything that may "short circuit" him, such as water.

ABILITIES 

Gifted Intellect: Dillion is a genius on his universe, knowing all about electrical energy and devices. But he is ultimately weak minded when he believes Spider-Man betrayed him and recklessly let Green Goblin manipulate him when all the Spider-Men tried to do was help him. 

Expert Engineer: Dillion is an expert electrical engineer in his universe, and was able to use the Arc Reactor to his liking, despite never having the tech before.
