United Federation

The United Federation is effectively the U.S.A. of Sonic's world. Populated by humans, the Federation is led by a President who works from a building highly reminiscant of the American White House. G.U.N. appears to function as the Federation's military.

It is worth noting that the United Federation dosn't appear to be a 'World State'; in Sonic the Hedgehog (2006), Soleanna is strongly implied to be a wholly independent nation with its own monarchy. G.U.N. dosn't seem in too much of a rush to help the inhabitants of Monopole during Sonic Riders: Zero Gravity either.
