He only works on one end of the spectrum or the other. Either Sonic and Eggman are equals or Eggman is the absolute authority to defy.

If they're both individuals who do as they please, Eggman gets to be charismatic and has more flexibility. He does bad stuff, but never actually manages to cross absolute moral lines with fuzzy cartoon logic allowing the audience to accept that he just needs a walloping and maybe he'll learn his lesson one day (never). It lets you explore stories with and without him, makes Sonic the focus. If Eggman is the world controller, the centralized authority, he becomes the butt of all jokes and the story revolves around him. The ousting is an endless struggle and Sonic can poke fun because they're the only real wins he'll ever get.

The American comics always tried to get in the middle, and it just doesn't work. If Eggman controls a lot of the world but not the majority, he becomes a major threat that it's irresponsible to not prioritize at all times, but his relative weakness means he's not as interesting and you wonder why he's still around.
