List of countries

Many fictional countries have been seen throughout the Sonic games, on Sonic's version of Earth., all of which are based on real-world locations. Some are minor and appear only in one game, and some are vastly important and appear multiple times.

United Federation
The country featured in nearly every game in the series. It is based off of the United State sof America, with a republican government and a President who lives in the capital; Central City. It's govenment is the Guardian Unit of Nations, or GUN, which has two known bases: Prison Island and the GUN Fortress. It can be assumed that Empire City is located in the United Federation, as both are based on America.

Eggman Empire
Otherwise known as Eggmanland or Robotnikland, this is a dream Doctor Eggman aspires towards, using threats such as destroying the United Federation with the Eclipse Cannon should they refuse to give him control. With the help of Dark Gaia in Sonic Unleashed, he temporarily succeeds in his goals, although it was destroyed following Sonic's victory, leaving only the capital metropolis remaining. During a final raid on the Metropolis two years before Sonic Chronicles, that, too, was destroyed. At the end of Chronicles, Eggman has remade his empire with no resistance, as Sonic and friends were gone in another dimension.

Soleanna
The first location to be absolutely confirmed nto to be a part of the United Federation, aside from the mostly uninhabited Angel Island. Soleanna is a constitutional monarchy, ruled by those called either Duke or Princess, rather than King or Queen. The current ruler is Princess Elise the Third, orphaned daughter of the previous [Duke of Soleanna]], who died ten years prior. Its main industries are tourism and precision machinery. Soleanna's major religion appears to be a worship of the Sun God Solaris. It is unknown if the other people of the world follow this religion, or if it is exclusive to Soleanna. Soleanna's capital city is also named Soleanna, though it is sometimes called the City of Water. Two-hundred years into the future, the nearest city to the capital, the more modern New City, becomes the site of the Demon Iblis' attacks, and is known as Crisis City to the few survivors. In the good future that is created when Iblis is destroyed in the ending of Sonic 06, it can be assumed that Blaze's kingdom is Soleanna.
