The vigilante believes that corruption pervades society, and by extension, the very institutions intended to protect us from evil. Thus, the vigilante believes that only independent agents and unorthodox methods are capable of solving the world’s ills. This insight often manifests as a revelation triggered by trauma. It is at this point that the vigilante becomes proactive and steps outside of normal society by creating a new identity.
For the vigilante, the ends justify the means. The earliest vigilantes (~1200: Robin Hood, 1905: The Scarlet Pimpernel) are wealthy gentlemen who adopt colorful dual personalities in order to defeat tyranny. These costumed personas serve as a rallying point for like-minded resisters. The vigilante uses a specific “calling card” for easy recognition, such as a simple arrow or a picture of a flower.
In the pulp era of the mystery men, the dual identity transforms into a secret identity (1919: Zorro, 1931: The Shadow, 1933: The Spider, 1936: Green Hornet). Masks are introduced to disguise the vigilante from his enemies. Often, a cape remains as a reminder of the character’s aristocratic roots. Emphasizing his separation from civilization, the vigilante now prefers to operate at night and establishes a hidden base of operations.
Quintessential vigilantes (1939: Batman, 1940: The Spirit, 1941; Green Arrow) appear soon thereafter in the Golden Age of comics. For example, Bruce Wayne possesses all of the tropes of the archetype: aristocratic background (millionaire), colorful persona (“The Batman”), disguise (costume with cape and mask), a calling card (batarangs and other chiropteran symbology) and a subterranean hideout (the Batcave).
In the Silver Age, although writers experiment with working class vigilantes (1964: Daredevil, 1967: The Question), the vigilante is largely assimilated into the generic superhero archetype.
Heading into the Bronze Age, the vigilante evolves into its most popular form: the anti-hero with an alter ego that is either disregarded (1974: The Punisher) or fractured (1975: Moon Knight). Frank Castle has no need to be anyone other than simply The Punisher. Moon Knight sees himself as the avatar of an Egyptian god; his multiple personalities are unintended consequences of his crusade.
The deconstruction of the archetype culminates with Alan Moore’s anarchist revolutionary (1982: V for Vendetta), a Batman persona that tears down the Bruce Wayne façade (1986: The Dark Knight Returns) and the morally absolute Rorschach (1986: Watchmen). This extreme interpretation of the vigilante has flourished for almost twenty years.
