An unusually configured magnetic field was created when Dillon was struck by lightning while holding live, high-tension wires and a wound reel of one-inch cable, granting him superhuman powers. 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.

When his body is charged to high levels, he becomes superhumanly strong and fast. He can also glide over power lines by using the electricity contained therein for propulsion, and he has on occasion been shown to actually ride on lightning bolts. During a stint in prison, Doctor Octopus gave him the ideas of ionizing metals and sparking the petroleum in the fuel tank of a vehicle as a way to generate explosions. He can charge himself up to make himself more powerful. He can also absorb the energy of electrical equipment such as a power plant to increase his powers further.
