Monster League of Evil

The Monster League of Evil are a group of supervillains in the DC Comics universe. They are enemies of Captain Thunder and are real-life versions of the Hollywood movie monsters Frankenstein's Monster, Dracula, the Wolf-Man, and the Mummy. Their origin is an alternate Earth known as Earth-276.

History
The Monster League of Evil would make their first appearance, as well as their last conflict, fighting the superhero Captain Thunder. They fought him across 1,953 dimensions of time and space before they would eventually be defeated. The Monster League of Evil would then be imprisoned in a fog-filled limbo by Captain Thunder. However, before Captain Thunder left them, the Monster League of Evil warned him that they had done something to him in revenge for their imprisonment. It was later revealed that Captain Thunder had figured out that the Monster League of Evil were somehow able to give him the compulsion to commit evil acts (this was after he accidentally appeared on Earth-One). Fortunately, though, Superman (from Earth-One) was able to assist Captain Thunder to become free of his compulsion and Captain Thunder would return to his own universe (Earth-276).
