The Gorillaz 'Demon Days' cover parodies stem from the iconic 2005 album artwork featuring the four band members—2-D, Murdoc, Noodle, and Russel—in profile against different colored backgrounds in a 2x2 grid. Because of its clean, distinct aesthetic and easily replicable structure, it became one of the most parodied album covers in internet history. Fans and digital artists frequently replace the band members with characters from other franchises, such as The Simpsons, Star Wars, or popular video game casts. These parodies celebrate pop culture crossovers while paying homage to the visual style established by artist Jamie Hewlett, making it a staple template for character-based fandoms and creative mashups.
