The Checkered Demon is a fictional character created by S. Clay Wilson, one of the leading underground comix artists of the 1960s.

A portly, shirtless being generally seen wearing checkered pants, the Demon emerged from Wilson's experience of watching Federico Fellini's 1965 film Juliet of the Spirits while on LSD.

[3] The Checkered Demon is frequently called upon to kill the various demented bikers, pirates, and rapists who populate Wilson's universe.

The Demon is unbeatable in combat, but prefers to copulate with rapacious women—such as Star-Eyed Stella, Ruby the Dyke, or Lady Coozette—or to sit around drinking Tree Frog beer.

[4] The song "The Checkered Demon", inspired by the character, is part of the American hardcore band AFI's debut album, Answer That and Stay Fashionable (1995).
