Mobius (Archie)


 * For the version of this planet after the Super Genesis Wave, see Sonic's World.

Mobius, also known as Mobius Prime due to its place in the multiverse, is the previous main setting of the Sonic the Hedgehog and its spin-off comic series published by Archie Comics. It is actually an older version of Earth, approximately 12,000 years into the future, with Mobius' calendar year at mid-late 3237. It is still unknown exactly what was the starting point for their calendar, but it was likely calculated using what the Echidna Tomes call the Days of Fury.

Mobius has endured many conflicts, including the Great War, the first and second Robotnik Wars, and a failed attack by the Xorda. Much of it was also under the control of the Eggman Empire, though some sections of it remained free from its tyranny.

Prehistoric
Nearly 12,000 years ago, during the 21st century of the "old world" when Mobius was still known as "Earth", an alien race known as the Xorda came to the planet to offer an alliance to its human population. However, the emissary they dispatched was captured, studied and subsequently dissected by a group of scientists led by Ivan Kintobor, a leading scientist at the time. Ivan had hoped to use the captured alien and its technology to produce the robot Isaac as well as numerous other creations. His methods however proved antagonistic towards the Xorda. In retaliation, the aliens bombarded the planet with Gene Bombs with the intention of exterminating all life on the planet, melting all surface life into primordial ooze. Before the destruction of the planet's biosphere, however, a number of hidden cities were constructed, safe from the effects of the Gene Bombs. The bombs had an unforeseen side effect however. Rising from the primordial soup, DNA from the former human population formed the four-fingered Overlanders seen on Mobius today, while the rest of the animal kingdom also experienced a rapid evolution from interaction with human DNA, forming modern-day Mobians.

Early history
Approximately 10,000 years ago, the planet suffered a massive environmental cataclysm. The Gene Bombs were supposed to preserve Earth's environment as it was when it was attacked. However, their interaction with the planet caused massive volcanic reactions, earth quakes, and massive storms, hurling billions of tons of ash and dirt into the air. This is what is chronicled as the first Days of Fury in Echidna theology.

Shortly after this cataclysm, the event known as the "Coming of the Chaos Emeralds" occurred. Mysteriously, the green Chaos Emeralds reigned down on the planet from the sky. This resulted in dramatic global weather changes, eventually causing the extinction of the Mobosaurs. However, it also gave rise to the omnipotent beings known as the Ancient Walkers and provided immortality to Mammoth Mogul, when one of the descending Chaos Emeralds embedded itself in his chest. It also allowed the Mobo-sapiens, known more simply as Mobians, to become the new dominant race on the planet.

The Days of Fury continued to affect Mobius for thousands of years, right up to modern day. The Echidna Tomes describe them as "natures way of adjusting to environmental changes it undergoes over a certain duration" according to Athair. Prior to the Day of Fury which happened in the year 3235, Athair stated the last recorded Day of Fury happened some "twelve hundred years ago".

At some point in time, the early dragons were supposedly born in the Dragon Kingdom region of Mobius. The dragons warred amongst themselves for generations, until they realized the destruction wrought on the land. After this the various dragons settled throughout Mobius. Mobius' early history also saw the rise of two more super-powerful beings connected to the Chaos Force: Aurora and Enerjak, who were formerly research scientists in Albion. Sadly, Enerjak became corrupted by his powers, and Aurora and the Ancient Walkers were forced to scatter his being throughout the Chaos Force.

Approximately 9,700 years ago, the Echidnas were already well developed in their colony of Albion. The Albion Knights of Aurora found themselves defending the planet against the wizard caste known as the Order of Ixis, which was bent on world domination and was subservient to their founder Mammoth Mogul. Events in the war included the appearance of Mutates, the invention of cybernetics, the mutation of the Tasmanian Devil, and the rise of the second Enerjak. Despite the Order's incredible powers, the Albion Knights successfully defeated Mogul during the Forgotten War, effectively wiping out all of the Order of Ixis. However, Mogul and three later disciples, Agunus, Nusgau, and Suguna, survived the Forgotten War. The latter three wizards eventually merged to form the individual wizard Ixis Naugus thousands of years later. It was also during the Forgotten War that monstrous creatures of various species, collectively known as Mutates, began to appear across the planet, though in limited numbers.

Developing societies
Approximately 1,000 years ago, Dave, an Echidna from Albion, ventured out into space, exploring Jupiter and its moon Europa on his ship the Monolith. The Echidnas made other advances down through history as well, one group going so far as to leave Albion in order to resettle elsewhere. After briefly stopping in Soumerca, where two factions of the colony effort-the Knuckles Clan and Nocturnus Clan-broke off to fight for the land they hoped to claim, the other group settled in Downunda, where they built the city of Echidnaopolis.

Approximately 600 years ago, a White Comet hurling towards Echidnaopolis was discovered by the Echidna scientists Jordann and Kayla-La. Using their knowledge of the Chaos Emeralds, the two scientists managed to use the Chaos Emeralds' powers to lift their city into the sky, after the Fire Ants dug underneath the city to separate it from the continent — thus creating the Floating Island. Sadly, the Echidnas would face further troubles of their own, beginning when the scientist Dimitri attempted to return to the island to the surface using his Chaos Syphon, only to be driven mad. This would also lead to the creation of the office of Guardian among the Echidnas of the island.

Meanwhile, the other Mobians learned from the Echidnas on how to structure themselves into societies. One Mobian, Alexander, decided to pool the various groups resources and knowledge together to form a single society. While the Overlanders proved too violent in nature to be included, and the Echidnas chose to exclude themselves from joining the group, the other Mobians pulled together and created Mobotropolis - the first multicultural city on the planet.

Measurements

 * Weight: Measured in Stone (1 Stone = approximately 6.35 Kg or 14 lbs)
 * Height: Measured in Marks (1 Mark = approximately 1.4 cm or a little over 1/2 inch)
 * Month/Day Calculations: This measurement is used for the characters' comic profiles. For example: if a character was born Day of birth: 162, that would work out to June 11. Since each Mobius year is 365 days, each month corresponds for a certain set of numbers as seen below:
 * January: 1 through 31
 * February: 32 through 59
 * March: 60 through 90
 * April: 91 through 120
 * May: 121 through 151
 * June: 152 through 181

 * October: 274 through 304
 * November: 305 through 334
 * December: 335 through 365

Trivia

 * In the issues leading up to Worlds Collide, the comics seemed to be going to great lengths to avoid referring to the planet as Mobius. Most notably, the heading at the start of each issue, which originally began with "Welcome to the planet Mobius" had been changed to "Welcome to Sonic's comic book adventures", and other instances where the planet's name would usually be mentioned is changed to simply "Sonic's World" instead. A recent post by Ian Flynn revealed that a Sega mandate has stated that Sonic's world cannot be named, thus the name "Mobius" has been dropped.
 * The first map of Mobius shown in Sonic Super Special #2 showed the "Land of a Million Lights" to be located in the "South Africa" part of the planet. However, the map shown in Sonic the Hedgehog #194 located it where the Lethal Radioactive Zone from the first map was. The new map also listed Station Square in the location the Mysterious Cat Country was located on the older map, instead of just being located nearby. It is unknown if these were retcons or simply mistakes.
 * Oddly enough, most of the game-related zones mentioned or shown in the comics remain unspecified on either maps. Among them are Bingo Highway and Frog Forest from Sonic Heroes, Wild Canyon from Sonic Adventure 2, Sky Canyon from Sonic Advance 2, Club Rouge and Holy Summit (misspelled Holly Summit) from Sonic Battle, Windy Valley and Red Mountain from Sonic Adventure, and South Island from the classic titles.
 * The name Mobius may be a reference to a shape known as the Möbius strip, a shape with no clear start or end that appears to have multiple sides, when in fact there is only one. This could be intended as a reference to the cyclical nature of species dominance on Earth/Mobius.
 * The name Moebius, which refers to the alternate version of Mobius from which Scourge hails, may be based off of Möbius syndrome, which is also spelled Moebius, an extremely rare congenital neurological disorder which is characterized by facial paralysis and the inability to move the eyes from side to side. This description could arguably characterize the distorted personas of Scourge and his Supression Squad as well.
 * Mobius' landmasses are similar in shape to Earth's, but are fragmented, hinting how it is a future version of earth.
 * Backing up the theory that Mobius has similar geographical locations to Earth, Geoffrey St. John mentioned "Soumerca" once, followed by an author's note clarifying "Mobius South America."

Year

 * The exact date of the Mobian calendar is unknown, but by day counting from Sonic's last birthday in Sonic the Hedgehog #160, the first Genesis Wave was launched on day 184, 3237, and the second about nine days later. While it would have been 3238 had Sonic spent a full year in space, Sonic the Hedgehog #155 had Tails state he was still eleven, and in Sonic the Hedgehog #157 Dr. Eggman's computer monitor clearly showed the year as 3237.
 * It is unknown what year the early Sonic the Hedgehog issues take place. However, Sonic the Hedgehog #188 established that Sonic was eight-years-old when he first fought against the Super Special Sonic Search and Smash Squad, placing issues with them at 3228, but Tails would have been three and not old enough to be a freedom fighter. It is known that Dr. Robotnik was defeated in 3235 as he was said for have ruled for ten years, and the year 3236 came into being some time before Sonic the Hedgehog #69, as Sonic officially turned 16 then. A rough estimate of what year the Sonic the Hedgehog issues take place would be as such:
 * Unknown: Sonic the Hedgehog #1 — #24
 * 3235: Sonic the Hedgehog #25 — #57
 * 3236: Sonic the Hedgehog #58 — #125
 * 3237: Sonic the Hedgehog #130 — #247
 * As of Sonic the Hedgehog #148 (Mobian year 3237), Ivan Kintobor was born 12,010 years, 11 months, and two weeks ago, in the Earth calendar date June 6, 2006, putting Mobius' date at May 20, 14,017 CE.
