South Island
First seen: Sonic the Hedgehog (1991)
Type: Island

South Island (サウスアイランド)Media:Sonic1 MD JP manual.pdf[1] is a location found in the Sonic the Hedgehog series of video games and auxiliary material. It was introduced in the original Sonic the Hedgehog for the Sega Mega Drive. It has featured in a number of Sonic games over the years, being the primary location for most of the main titles on the Sega Game Gear. A "treasure trove of gems and ruins,"Media:Sonic1 MD JP manual.pdf[1][2] it is also home to arguably the most iconic stage in the Sonic series, the Green Hill Zone.

Description

South Island, as seen in Sonic Origins Plus.

Floating somewhere in the ocean, South Island can not be found on any map as its location constantly changes. The isle moves freely about the water, not anchored to any one position. It is said this movement causes distortions, creating a "special stage" in which the Chaos Emeralds lie hidden.Media:Sonic1 MD JP manual.pdf[1]

The island is a lush tropical paradise, characterized by its numerous palm trees, colorful flowers, and green flora. Endless blue skies stretch over its most famous locale, the Green Hill Zone and its checkerboard terrain. Numerous waterfalls roll down mountains and hillsides, flowing into a large lake found in the center of the island. The lake itself flows out into the ocean from South Island's southeastern edge. The northern and eastern coast of the island are mountainous, steadily rising higher until it reaches its peak near the northeastern corner.Media:SouthIslandMap.png[3] It is the peak of this mountain range that Dr. Eggman built his first fortress on the island, Scrap Brain Zone.Media:SouthIslandSummit.PNG[4] The natural topography also includes a jungle area as well as a small desert zone.

While green dominates the landscape, a number of modern structures have been built on the isle in locales such as the Starlight, Spring Yard, and Gigalopolis Zones. There are also a handful of areas covered in the ruins of an ancient civilization.[5][6]

Fictional history

Close-up of the island's industrialized summit, from the 8-bit version of Sonic the Hedgehog.

Not much is known about the ancient history of South Island. Ruins dot the landscape, primarily in the Marble and Labyrinth Zones, hinting at a civilization which once called the island home. What happened to the people who built those structures is currently unknown.

Prior to the events of Sonic the Hedgehog, Dr. Eggman arrived on the island, learning of the existence of the Chaos Emeralds and the island's connection to them.Media:Sonic1 MD JP manual.pdf[1] Eggman began to kidnap the animals living on South Island, placing them inside robots and using them in his plot to take over the world. At the same time, he built his Scrap Brain Zone base in the mountains of the isle. Hearing rumors that Eggman had begun to cause trouble, Sonic the Hedgehog rushed onto the scene, and as he had done before, went up against the mad doctor and his evil ambitions.Media:Sonic1 MD JP manual.pdf[7] Collecting the emeralds and freeing his animal friends, Sonic was able to stop Eggman and bring peace to the island once more.

This would not be the last time Dr. Eggman set his sights on the island. Some time after Sonic met Miles "Tails" Prower, Eggman kidnapped both the young fox and the other animals who lived there, holding them prisoner until Sonic was to deliver the six Chaos Emeralds to his new base, Crystal Egg Zone.Media:Sonic 2 GG JP Manual.pdf[8]Media:Sonic 2 GG JP Manual.pdf[9] After this failed, he would try to gather the emeralds yet again, inadvertently causing the island to start sinking into the ocean.Media:Sonic Chaos Game Gear JP Manual.pdf[10]Media:Sonic Chaos Game Gear JP Manual.pdf[11] The island would be saved, and in turn Eggman stopped, by both Sonic and Tails.

South Island would play host to the Chaos Grand Prix[12] as seen in Sonic Drift. It would also be the home of the first version of "Eggmanland," in this incarnation a giant labyrinth, built prior to the events of Sonic Labyrinth.Media:SonicLabyrinth GG JP manual.pdf[13] It would also be the launching pad for his flying fortress known as Silver Castle.

Life would remain relatively peaceful on South Island until the events of Sonic Forces. The island would be host to the start of Eggman's nearly successful attempt to take over the world, Green Hill becoming the first casualty.[14] One of the island's cities would serve as a base of operations for the Resistance until Eggman was successfully overthrown.[15][16]

Sonic the Hedgehog Story Comic

File:MegaDriveFan JP 19910701 f.pdf In the three volume Sonic the Hedgehog Story Comic published in Mega Drive Fan, South Island serves as the primary setting. It is a peaceful island which no one knows of.[43] As the comic advertised the original Sonic the Hedgehog,[44][45] the island features the same zones as seen in that game. The topography is covered in green hills, palm trees,[43] ancient ruins,[46] and modern structures.[47] A sandy beach can be seen on the southern coast. A mountain range also encompasses a fair amount of the island's northern coast,[43] where Eggman's base is built.[48]

The population of the island is made up primarily of talking animals.[49][45] There are also a handful of humanoid women known as "Sonic's Bodyguard Platoon" who watch Sonic the Hedgehog perform with his rock band in the Green Hill Zone.[50]

Sonic the Hedgehog (Archie comics)

The cover of Sonic the Hedgehog #288, featuring South Island.

In the Sonic the Hedgehog comic series published by Archie Comics, South Island is originally an unseen location that exists on the planet Mobius. As King Acorn prepared to go on a tour of the planet to rally support against Dr. Robotnik,[51] a sticker bearing the words "South Island" was on one of the many pieces of luggage that accompanied the king and his entourage.[52]

After the Super Genesis Wave, South Island was just one of the many territories that was part of the Kingdom of Acorn. After Dr. Eggman took over Mobotropolis and sent King Nigel Acorn to the Special Zone,[53] he and Dr. Julian Snively traveled to the island and began aggressively mining it, looking for the Chaos Emeralds. In the wake of Eggman's sudden takeover, Sonic followed the doctor to South Island, fighting his robot forces across the many zones that make up the isle.[54] Collecting six of the seven Chaos Emeralds,[55] he was able to stop Eggman and Snively, the duo retreating to Westside Island.[56]

Sonic would return to South Island some time later to rescue his friend Miles "Tails" Prower, who had been kidnaped by Dr. Eggman.[57] Meeting Breezie the Hedgehog, he would end up in such locations as Underground Zone[58] and Scrambled Egg Zone.[59]

Sonic the Comic

Sonicretro-round.svg This short section needs expansion. You can help Sonic Retro by adding to it.

In Sonic the Comic published by Fleetway Editions, Ltd., South Island is the home of numerous "Hill Zones," including Green Hill Zone and Emerald Hill Zone. In the northern part of the island exists the Frozen Zone, "a zone of perpetual winter."[60]

South Island from above. From Sonic the Comic #25.

The island is home of the Emerald Hill Folk, the residents of the Emerald Hill Zone. It was also the adopted home of Dr. Ovi Kintobor, who built his secret underground laboratory in the region.[61]

South Island was a peaceful place until the day Kintobor transformed into Dr. Ivo Robotnik, who immediately set off to take control of the planet Mobius. Initially, his plans were thrwarted by Sonic the Hedgehog, until Robotnik was able to take control of the Omni-Viewer.[61] Sending Sonic six months into the future, Robotnik was able to take control of South Island and the world.[62] This remained the case until Robotnik was finally overthrown by Sonic the Hedgehog and the Freedom Fighters.[63]

Sonic the Hedgehog (anime)

Sonic's home, one of the many islands that make up South Island. From the anime Sonic the Hedgehog.

In the original Sonic the Hedgehog anime, South Island is a collection of floating islands governed by the President. Existing in the Land of the Sky of Planet Freedom, the many islands of South Island feature a variety of topographical wonders, including lush greenery, lakes, and modern man-made structures. A variety of anthropomorphic and humanoid beings live on the many land masses that comprise South Island. Travel between the islands is done by aircraft.

The most prominent collection of floating islands is where the Presidential Palace lies. It is comprised of two parts - one massive floating isle with a large modern city, and another floating isle with several smaller islands connected to it by land bridges. Sonic's home is also part of South Island. Two other cities are known to exist in the collective, Green Lake City and Forest Town.

During the two episode anime, South Island is threatened by Dr. Eggman, who invades the Presidential Palace and kidnap's the President's daughter, Sara. Sending Sonic and Tails to the heart of Eggmanland, Eggman is able to scan Sonic, using his life data to finish his greatest creation, Hyper Metal Sonic. This robot version of Sonic attacks various regions of South Island, setting Forest Town on fire and destroying Green Lake City.[64]

Dash & Spin Chousoku Sonic

Sonic, Tails, Knuckles, and Amy Rose all visit South Island during the fourth chapter of Dash & Spin Chousoku Sonic. Searching for a romantic hidden treasure, the quartet learn that Dr. Eggman is fishing off the coast of the island, also searching for the same treasure.Media:Dash&spin 1 Ch. 04.PDF[65]

Sonic the Hedgehog (IDW comics)

Sometime before the events of Sonic Superstars, the Hard-Boiled Heavies appeared above South Island aboard their ship, the Heavy Wing. Attacking the Marble Zone, the ship vanished afterwards.[66]

Sonic the Hedgehog (film series)

The home of Sonic in his early years. From the film Sonic the Hedgehog.

In the film Sonic the Hedgehog, a young Sonic the Hedgehog grows up on an unnamed island. Though the island is unnamed, its design is based on the look of South Island from the original video games.[67]
