Dr. Robotnik is originally tall and lean. He has a full head of chocolate brown hair (almost black) in an undercut style, along with a large elegant mustache, a normal, healthy-looking nose, brown eyes, fair skin, and ample stubble across his jawline. Robotnik really hates society as a result of not being nurtured, loved, or guidance in his early life, and that's what he's become the epitome of that, and hates the world so much that it "abandoned him". He has 5 PhDs and a 300 IQ.
