Dr Eggman, also known as Dr Robotnik, has been Sonic the Hedgehog's main antagonist since the first Sonic game released by Sega in 1991. The eccentric scientist is known for building robots and machines to defeat Sonic, and his booming, theatrical voice acting across games, cartoons and films made his lines highly memeable. Short clips of his voice circulate on soundboards and in fan edits, where they are reused whenever someone is playing the exaggerated villain, announcing a scheme or celebrating a devious idea.
