Dr. Ivo Robotnik or Eggman, as he is most commonly known, is Sonic's arch-nemesis and therefore Un-American and a communist since Sonic is a red-blooded American providing fun and joy for Dr. Colbert in is free time (along with Mario). He is an awful yet persistent machine maker/creator/manufacturer trying to outwit the courageous freedom-fighter Sonic but fails over and over again. Thankfully Sonic is there to help fight in the War on Terrorism and Hippies! RUN SONIC RUN!!! RUN YOUR LITTLE FREEDOM FILLED HEART OUT!
