Zone Leaders are the governing figures of post-RBR Mobius. Rather than adopt a new central government to occupy the position that Doctor Robotnik once held, the Mobians - under suggestion from Sonic the Hedgehog (in "Vote For Me") - decided that each Zone should have its own ruler.

Most Zone Leaders are democratically elected, and they tend to distinguish their office with a mayoral-style medallion. Known exceptions to the democratic model include the Coal Creek Zone, where the Zone Leader is a military dictator ruling by force; the Hill Top Zone, which retains its traditional aristocracy and nobility; and the Chemical Plant Zone, a corporate canton with the Marxio Brothers as its executive directors.
