The Cacodemon is one of the most recognizable enemies from the legendary first-person shooter series DOOM, first appearing in 1993. Known for its spherical red body, singular eye, and gaping maw, the Cacodemon became a fan favorite due to its unique design and satisfying death animation. In internet culture, the Cacodemon has evolved beyond the game, appearing in various 'pog' edits (the CacoPog), wholesome fan art, and reaction images that contrast its demonic nature with goofy expressions. Its simplistic shape and expressive features make it a versatile canvas for meme creators looking to blend 90s nostalgia with modern internet humor.
