Insulated Spider-Man: This alternate costume was created by Spider-Man to counter the devastating electricity powers of the super-villain Electro. By utilizing non-conductive materials and building on his original "rubber air mattress" design, he defeated Electro with ease.

Electro: Given super-human powers by a freak electrical accident, Max Dillon was transformed from an average electric company lineman into the super-villain known as Electro! Able to absorb and manipulate near-limitless amounts of electricity, Electro can only be defeated by shorting out or overloading his powers.
