isn't eggman the nickname that he adopts? his real name is robotnik, so shouldn't he be tagged robotnik, rather than eggman?

besides that, I always found it funny that in all of his intelligence, he never realzed that calling him eggman was essentially making fun of himself.

Look up the wiki. He'll always be Robotnik for me. :(

He could be like fat joe or notorious big, dudes who embrace their largeness as part of their gangster identity.

Looks like the ending of Sonic 2 to me.

Well Yuji Naka says so too, which is about as high an authority that will ever comment on the matter I figure.
