Dr. Robotnik is a million times better name than Dr. Eggman. Eggman just sounds like a joke, which admittedly is what the series has become to me.

Back before anyone spoke in S2 & S3 the Sonic sprite always looked pissed off to me, and with the whole DBZ Super Sonic and what looked like a world destroying Death Egg I tended to have a more serious take on the Sonic universe than Sega seems to have.
