Dr. Robotnik

Dr. Ivo Robotnik better known by the alias Dr. Eggman is the main antagonist of the Sonic the Hedgehog series. He is a human and the arch-nemesis of Sonic the Hedgehog. This large scientist with an IQ of 300 dreams of dominating the world, but his constant plots to create his Eggman Empire (a.k.a. Eggmanland) are always thwarted by Sonic and his friends.

Why He Rocks

 * 1) He is one of the most famous villains in video game history.
 * 2) He is totally not what you not expect from a fat guy with a funny mustache.
 * 3) Eggman's many incarnations treat him in very different, from very threatening to very goofy.
 * 4) He is like the perfect opponent to Sonic, it's the eternal battle between the blue, light-hearted, super-fast, super-powered and courageous hedgehog and the fat, nerdy-looking, selfish and sometimes childish old guy in red.
 * 5) He makes every battle he has with his enemies count.
 * 6) He is an emperor, a dictator a stylish billionaire ruling with an iron fist over an entire nation made of nothing more than machines.
 * 7) Also, despite being fat, bald, mildly unattractive and with a despicable personality, he can be a gentleman, a wealthy philanthropist, a man who can be so captivating to the point of fooling others into doing whatever he wants.
 * 8) Most villains or anti-heroes are nothing but uninteresting, forgettable fellows who are usually never used in the series again, while Robotnik is a well-developed and sometimes even sympathetic antagonist who keeps coming back. He became so important to the franchise that Sega just can't replace him.
 * 9) Robotnik keeps coming back, he is so desired and so important to the series that putting someone else in his place is nothing but a crime to the fanbase and it took a while for the creators to figure that out.
 * 10) He's been in more games than even the main character himself.
 * 11) "Snoo-ping as usual,I see".
 * 12) " I HATE THAT HEDGEHOG!"
