Dr Eggman, also known as Dr Ivo Robotnik, is the main antagonist of Sega's Sonic the Hedgehog series, which began in 1991. His exaggerated cartoon villainy, round design and theatrical delivery have made short clips of his voice popular outside the games. This hehe laugh circulates on soundboards and in short meme edits, where it is detached from any specific scene and reused as a general reaction for scheming, gloating or pretending to be the villain. Its brevity keeps it easy to insert into fast edits.
