There could be many reasons:


 * 1) So he looks like an egg.
 * 2) Because he's based on Theodore Roosevelt.
 * 3) Possibly because Eggman is meant to represent the power-hungry, nature-replacing aspect of humanity.
 * 4) To create a contrast with Sonic, a fast-moving, and therefore healthy, character and the series' protagonist.
