The Lost Hex (ロストヘックス Rosuto Hekkusu?) is a location that appears in the Sonic the Hedgehog series. It is a mysterious, unexplored continent floating in the sky above Sonic's world,[1] and houses a variety of different areas. Lost Hex is also home to the Zeti, a race of creatures that include the Deadly Six.


The Lost Hex is made up of many hexagonal plates. Each of them is a piece of land or sea. They are either connected to each other or separated by large gaps. Together, they form somewhat of an incomplete sphere. The Lost Hex also has no nucleus, as the continent has only an empty space in its center. However, despite what its appearance might imply, it is not an independent planet, but rather one of the satellites that orbit Sonic's world.

The Lost Hex's surface consists of numerous ecosystems. The continent features grassy meadows and hills, deserts, dense forests, snowy mountains, tropical coasts, and valleys filled with lava and volcanoes. However, characteristic that all these locations share are simple shapes that dot the landscapes, such as squares and rectangular cubes. There are also floating landmasses all over the Lost Hex in the shape of spheres or tubes in all kinds of shapes and sizes.

The Lost Hex is known as the natural habitat of Zeti. In addition, the continent is also inhabited by various Animals and Wisps, as well as other types of non-anthropomorphic animals such as giant crocodiles, fish and Sandworms. The Lost Hex ecosystem is overall clean and pristine. After Dr. Eggman's arrival here, several factories were built on the Lost Hex, but they polluted the continent to a very limited extent.


Sonic Lost World

In the Wii U version of Sonic Lost World, the Lost Hex was conquered by Dr. Eggman, who subjugated six local Zeti called the Deadly Six with the Cacophonic Conch. Eggman proceeded to set up his base operation and several factories on the Lost Hex where he worked on producing an army of Badniks, powered by kidnapped Animals, to conquer the world with. He also set up his Extractor, which allowed him to extract the energy from Sonic's world below.

While chasing Eggman, Orbot and Cubot in the Tornado, Sonic and Tails entered some turbulence when Eggman shot the Tornado, which let the duo discover a secret passage through the clouds to the Lost Hex. After landing there, Sonic and Tails went to work on saving Eggman's captive Animals on the continent. Meanwhile, Eggman would send the members of the Deadly Six after Sonic to stop him, although Sonic would emerge victorious from each encounter. Eventually though, when Sonic and Tails found Eggman scolding the Deadly Six for their failures, Sonic recklessly got rid of Eggman's Cacophonic Conch. With the conch no longer a threat to them, the Deadly Six rebelled against Eggman by using their powers to take control of his Badniks and attacking everyone present, eventually forcing Sonic, Eggman and their allies to retreat. As Sonic and Eggman then set out on their respective quests to stop the Deadly Six, said group began misusing the Extractor by using to slowly suck all the life out on Sonic's world to exact revenge on Eggman and Sonic, and obtain incredible power. Learning of the Extractor's activation, Eggman convinced Sonic and Tails to team up with him in order to get him past the Deadly Six and turn off the Extractor for them. This agreement brought some strain on Sonic and Tails' relationship, with Tails accusing Sonic of not trusting him to turn off the Extractor.

With Sonic continuing to oppose them, the Deadly Six decided to capture Sonic and turn him into their robotic slave. However, they ended up capturing Tails instead. Continuing onward towards the Extractor, Sonic seemingly lost Eggman when he saved him from falling into a lava canyon. Meanwhile, Tails tricked the Deadly Six into thinking that they had turned him into a robot. When the remaining Deadly Six later tried using the fox cub against Sonic, Tails returned to Sonic's side with a surprise attack, allowing Sonic to defeat the Deadly Six for good. When Sonic and Tails then turned to the Extractor, Eggman returned in his Eggrobo to conquer the remains of Sonic's world. Sonic, however, defeated Eggman, allowing Tails to make the Extractor return the world's stolen energy, thus restoring it. Afterward, Sonic made Eggman fall down from the Lost Hex. Sonic and Tails then returned home.

The Lost Hex, from Sonic the Hedgehog Halloween ComicFest 2013.

In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, Dr. Eggman conquered the Lost Hex and enslaved its locals, the Deadly Six, to find a different approach to the Shattered World Crisis. However, thanks to Sigma, a robot from a different dimension, Eggman was forced into serving Sigma and the Deadly Six, alongside fellow prisoner, Dr. Wily, on the Lost Hex. Eventually, the Lost Hex was turned into a battleground between Sigma and the Unified Army as the former emerged from the Lost Hex in more evolved forms. These events would later be erased from history by Xander Payne, although Eggman would return to the Lost Hex in the future to enslave the Deadly Six again.

During the Metal Virus pandemic, Dr. Starline visited the Zeti Castle on the Lost Hex to enlist the Deadly SIx for his and Dr. Eggman's attempts to control the Zombots. Secretly seeking revenge against Eggman, the Deadly Six agreed to be taken from the Lost Hex to Eggman's Faceship through a Warp Topaz portal that Starline opened for them.


  • According to a Japanese trailer that shows off the boss battles, Lost Hex is a "future continent". In the Japanese opening it is also described as a "continent of illusions" by Tails.
