Villainares describe the subculture obsessed with cataloging and discussing the exploits of super-villains. This group will write detailed profiles of super-villains, labeling them under categories such as: Mad Science, Supernatural, Mutant and Alien and endlessly arguing the factual controversies related to these categories.

Villainares clip newspaper articles, fill message boards and attend conventions to share information and listen to experts talk about recent news in super-villainy. Though sometimes considered to be freaks, the obsessive documenting by Villainares has often been of help to super-heroes seeking up-to-date information before they face a super-villain threat.
