Lightning Comics #5

In the 1942 issue of Lightning Comics #5, a deranged scientist, driven by vengeance, steals his half-brother’s blueprints for a flame gun and a formula capable of generating an impenetrable purple fog—solidifiable into a wall—and uses them to terrorize the nation from his fortress, "The Black City in the Sky." Facing him is the enigmatic Lash Lightning, whose powers put him on a collision course with the mad inventor. Penciled and inked by Jim Mooney, this early superhero tale blends pulp intrigue with the era’s signature flair, all rendered in bold, dynamic lines on a cover also by Mooney.
