Elec Man's Stage

Elec Man's Stage is an electric-themed stage that has Elec Man as its boss. It appears in the first Mega Man, its remake Mega Man: Powered Up, and Mega Man: Dr. Wily's Revenge. While its exact location(s) is unknown, it is usually assumed to be a power plant that Elec Man was working on before being reprogrammed by Dr. Wily, as Elec Man was originally created by Dr. Light to control the voltage of nuclear power plants.

Mega Man (Archie Comics)
In Issue 3 of the Archie Comics Mega Man series, Elec Man, having been reprogrammed by Dr. Wily, took over a power plant. However, despite his best efforts, including using the electric shocks of the plant to destroy Mega Man, Elec Man was dispatched easily by the Rolling Cutter. Also note that the background in the main control room is highly similar to the design of his stage in Mega Man Powered Up.
