Dr.RobotnikEditBig, Fat, and geniuss only explains one man...
This man has been in the villain empire since the beginning being sonic's mainman but always has been foiled(only if the players good!) in sonic 2,his main reference is him in the egg-o-matic but each time you battler him, it upgrades and gets harder and harder to defeat him.
Dr. Robotnik always has reminded me of uncle grandpa from cartoon network
with his fat belly,Huge mustach, gogges, and large red nose. Pretty handsome
