Many 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 in only one game, and some are vastly important and appear multiple times.

United FederationEdit

This is the country featured in nearly every game in the series since Sonic Adventure. It is based on the United States of America, with a republican government and a President who lives in the capital, Central City. Its military force is the Guardian Unit of Nations, or G.U.N., which has two known bases: Prison Island and the G.U.N. Fortress.

It can be assumed that Empire City is located in the United Federation, as both are based on America. It is worth noting that the United Federation doesn'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. doesn't seem in too much of a rush to help the inhabitants of Monopole during Sonic Riders: Zero Gravity either.

Eggman EmpireEdit

Otherwise known as Eggmanland or Robotnikland, 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: The Dark Brotherhood, that, too, was destroyed. At the end of Sonic Chronicles, Eggman has remade his empire with no resistance, as Sonic and friends were gone in another dimension.

SoleannaEdit

The first location to be absolutely confirmed not 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, 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.

The appearance of the capital city is based on Venice, Italy.

SpagoniaEdit

The world's art capital, located on the same continent as Apotos. Spagonia houses a university, which holds the lab of Professor Pickle.

Sonic speeds around the rooftops during his adventures here.

MazuriEdit

A locale based on various places in Africa, Mazuri is known for its reddish-brown soil, sandy citadels, desert expanses, and its large baobab trees, particularly the gigantic one near the village Sonic visits. Dr. Eggman comes to Mazuri in search of the Gaia Temple there, only to be thrown out by the locals (with Sonic's help). The continent in which Mazuri is located is also the first continent to be restored by Sonic after he defeats the Egg Beetle.

HoloskaEdit

The northern-most country at the North Pole based on Antarctica and the Inuit villages of the Arctic, Holoska is gripped with extreme cold and covered in snow.

Chun-NanEdit

This nation is inspired by Chinese culture and appearance with foggy mountains and waterfalls, giant dragon statues, bamboo groves, and lily pad-covered rivers and ponds. There are also brick structures that are identical to the Great Wall of China. The mountain town Sonic and Chip come to has a pork bun recipe that's been passed down for generations. The town's mayor, Zonshen, had disappeared at the time of Sonic's arrival. Sonic later finds him passed out in front of the Gaia Temple after he had most likely been attacked by the temple's guardian, the Dark Gaia Phoenix.

ShamarEdit

Based on the Middle East, Jordan in particular, Shamar is a sandy desert landscape with several rocky valleys and numerous ruins (one ruin in particular resembles the monastery carved into rock at Petra, Jordan). The desert town Sonic visits is host to the Hallowmoon Festival (also called Feast of Moon and Sun), a festival where the people of Shamar switch their daily life to nocturnal. The celebration is to honor the moon and the morning sun. Sonic arrives in Shamar after Professor Pickle tells him that he decided to pack up and move his lab there, as the Gaia Manuscripts say a lot about the town.

These places are either not ruled by any one government, far enough from their ruling government to not be labeled under that section, or the government ruling them is never stated.

South IslandEdit

The original home of Sonic the Hedgehog and the island which houses the famed Green Hill Zone. South Island is where it all began, as it is the first of many areas attempted to be taken over by Dr. Eggman and his robotic minions, and Sonic has stopped him each time ever since then.

Once part of the area in the present-day United Federation that is now the Mystic Ruins, Angel Island houses the remains of the ancient society of the Knuckles Tribe.

It houses the Time Stones and Time Posts, capable of sending someone either forwards or backwards in time. This was used by Dr. Eggman during Sonic the Hedgehog CD in an attempt to create the Eggman Empire. The planet makes a return in Sonic the Hedgehog 4: Episode II, where Eggman makes a second attempt to create his Empire once again.

Space Colony ARKEdit

Shut down fifty years ago, the ARK is a space colony in near-Earth orbit and is property of the United Federation. It was the workplace of Professor Gerald Robotnik, the home of Maria Robotnik, and the birthplace of Shadow the Hedgehog and the Biolizard, who are both Gerald's creations (the latter being the prototype of Shadow). Gerald created an extension of the ARK, the Eclipse Cannon, in order to destroy the Black Comet when it returned in fifty years time. However, the Guardian Units of Nations raided the ARK, believing that the space colony crew's experiments were a threat to humanity. During the raid, Maria was killed trying to save Shadow, which caused Gerald to spiral into irrational thinking. He then reprogrammed the Eclipse Cannon to use it as a means of revenge on the world, as it sent the ARK hurtling towards the Earth when fully activated 50 years later by Dr. Eggman. Sonic and Knuckles then used the Master Emerald to negate the effects that the seven Emeralds had on the Eclipse Cannon before the Biolizard fused with the ARK to carry out Gerald's plans. In the end, Super Sonic and Super Shadow destroyed the Biolizard and used Chaos Control to stop the ARK from smashing into the planet, although at the price of Shadow's life, who was believed to have died after falling back to Earth.

During the Black Arms attack on the Earth, they took over the ARK by using an amnesic Shadow to get through its defenses. They used the Eclipse Cannon to terrorize the Earth by destroying the White House, the capital of the United Federation. After Charmy Bee had struck the terminal of the ARK's main computer room, a hologram of Prof. Gerald (before he went insane) appeared. It told Shadow about how he needed help from Black Doom, leader of the Black Arms, in Shadow's creation, how Doom only helped in return for Shadow retrieving the Chaos Emeralds for him upon his return, and how Gerald created the Eclipse Cannon as a defense after he found out Doom's ulterior motives of world domination. The message motivated Shadow to confront Black Doom, who he defeated before using the Eclipse Cannon to finally destroy the Black Comet.
