Dr. Ivo Robotnik, better known as Eggman, is the longtime antagonist of Sega's Sonic the Hedgehog franchise, debuting in 1991's original Sonic the Hedgehog. His maniacal laugh has echoed through decades of games, cartoons, and dubs, becoming one of gaming's most recognizable villain sound bites. Online, the laugh spread through Sonic meme edits, fail compilations, and gaming montages, where it now functions as shorthand for any moment of cartoonish evil gloating, from a betrayed teammate to a villain finally getting their way.
