Sonic The Hedgehog (Main Continuity) Cosmology Page

Prime World

The main universe where the majority of the series takes place, housing countless planets and stars within it. The future of this world isn't set in stone and is prone to changing.

The Shatterverse

A “strange new multiverse” created by the shattering of the Paradox Prism, a crystalline artifact of immense reality-warping power. The Shatterverse houses five distinct worlds where Sonic never existed, with alternate versions of Green Hill Zone and his friends.

The inhabitants of each world have consequently lived entirely different lives, with different traits that drive their personalities, and Green Hill having met a different fate in each world.

New Yoke City

Boscage Maze

No Place

The Grim

Ghost Hill

• New Yoke City, a mechanized world under the autocratic rule of the Chaos Council.
• Boscage Maze, an overgrown jungle-themed world that overshadows the land below.
• No Place, an overflooded pirate-themed world where the peaks of mountains act as islands.
• The Grim, an empty world devoid of any form of life and only hexagonal crystal structures.
• Ghost Hill, a unique world that projects the original versions of Sonic's friends as phantom-like entities.

Upon being shattered, the Paradox Prism “fractured”/“splintered” the Prime World into a set of parallel dimensions dubbed "Shatterspaces". An emphasis was put on the fact that the Prime World wasn't simply altered, it was "broken", with it ceasing to exist entirely. Separate from the multiverse legitimate multiverse], each Shatterspace is a distorted version of the Prime World (i.e. the original universe). Shatterspaces contain their own celestial bodies, such as suns, moons, and stars, and are directly inferred to be entire universes of their own. Additionally, time is shown to flow differently within different Shatterspaces. Interdimensional travel between Shatterspaces is shown to only be possible via the space-time manipulating properties of the Paradox Prism’s “Prism Energy”, which enables teleportation/portal creation.

The Void

The space between the Shatterverse realities created by the Paradox Prism, filled with innumerable crystal-like shards of “debris” floating within it, serving as a short of nexus points between. The Void is shown to contain an “eternity of darkness” that “decays all life”, with other official translations implying that it means "infinite". That aside, the Void is of immense cosmic scope due to being large enough to encompass and house the five Shatterspaces.

Thus the Prime World is 2-C due to its smaller fragments after its destruction being enough to create 6 universal Space Times + all Cyberspaces created by Eggman that are contained inside of it, plus the Prime World would also be Infinite in size due to its smaller broken fragments creating an infinite space (The Void)

Artificial Worlds

This section is in reference to the various artificially created universes/dimensions/pocket dimensions crafted by individuals and/or factions with the technological advancement and capability to do so; one prime example being the Guardian Units of Nations.

Eggman's Tower Maze

During the events of the IDW Comics (particularly beginning with Issue #37 and ending around Issue #43), it was revealed that Dr. Eggman created a pocket dimension within a tower with the intent of testing his new Quasi-Badniks there. This space is continuously changing around those located inside it due to a spatial warping effect that's a result of Dr. Eggman bending the laws of physics to his will in order to create a space that circumvents spatial laws; allowing him to construct an autonomously tessellating, proportionally expansive structure with no limitations. Dr. Eggman could also freely control gravity within this space.

Even a "starry sky" and a tesseract is located inside of it (with tesseracts in question being inherently spatially 4-D), showing that this is a realm with four spatial dimensions.

Spatial-Displacement Trap

Later on in the IDW Comics (this time beginning around Issue #57 and ending at Issue #61), Dr. Eggman created a type of device named the Spatial-Displacement Trap. The first model makes the targets fall into another dimensional plane, where they are rendered utterly unable to interact with the world despite technically being part of it. The upgraded second model that, apart from the aforementioned effects, can scatter/displace one's atoms to oblivion until it's deactivated.

Cyberspace(s)

Ancient

Cyber Space is a reality made of information created by the alien civilization of The Ancients more than tens of thousands of years ago. Being a prominent part of their society it served as a short of mega collection of everything regarding them, their hopes, dreams, memories, souls and the very essence of who they were, serving as a mega server to all information regarding them as a way to pass on their legacy to the future generation, on top of it being a macrocosm of dreams it is also said be a dream in of itself. The amount of information in Cyber Space is said to be beyond quantification by Dr. Eggman, additionally saying that it is more advanced than the digital dimensions he has developed, which would include renditions of the Modern cyberspaces used by him, also said to exist in a different dimensional plane in comparison to the prime universe and is another space separated from the Prime World.

Modern

Similar in concept constructs used by the modern society, working as a "information highway system". Modern digital worlds exist as separate spaces from the normal space where the universe is, with some of them being infinite in size. They can be created & manipulated by either technological or supernatural means. Their purpose can vary from data storage, sealing powerful artifacts for safe-keeping, creating simulations of both people, and locations, and potentially far more.

Thus, the Ancients' Cyber Space is Low 1-C (5-D) for being a macrocosm of innumerable dreams (thus having a 5-D axis by default) and also being said to be infinite (as it is said to be superior to Modern Cyberspaces and even gathers data fragments directly them). It's also far more advanced than anything Dr. Eggman made by the time of Sonic Frontiers (a topic also accepted within this thread), including Cyber Spaces of his own making.

The Multiverse

The cosmology has multiple alternative universes throughout the series, with the alternative realities created with every possibility of what could have happened. The total number of realities being "possibly infinite".

Parallel worlds are only possible due to the "Power of the Stars", an energy that exists between them all, although the exact mechanics of this are yet to be elaborated.

Thus the Standard Multiverse is 2-B, possibly 2-A.

Special Stage Dimensions

Surreal alternate universes as backed up by the presence of asteroids, moons, planets, stars and nebula in several of them. This is where the Time Stones, Chaos Emeralds and Super Emeralds usually reside in, working as traps once one gets inside, only being able to be escaped once the gemstone or the Goal Block has been reached. There are several gateways that grant access to these spaces.

Sol Dimension

First introduced in Sonic Rush, the Sol Dimension is a reality that is inexplicably-yet-closely linked to Sonic's own. This is showcased primarily by the existence of the Sol Emeralds, but also through Blaze as a direct parallel to Sonic and Knuckles. In fact, Dr. Eggman and Dr. Eggman Nega even elaborate that their worlds are indeed parallel.

Sonic Runners Universe

This auto endless runner mobile game, while taking several elements from the main series, is actually revealed in the game story that it takes place in an alternate timeline, as the Sonic from Sonic Runners doesn't recognize the events and characters from canonical games like Sonic and the Secret Rings, while equally the events of said games are said to have happened and a "blue savior" is said to have defeated Erazor Djinn in the past, a clear reference to mainline Sonic and characters in it recognize Sonic as the said "blue savior" while the Sonic in Sonic Runners doesn't seem to recognize as himself, clearly pointing that another Sonic is the savior, aka the Sonic from the Prime World. Other elements that are different in this alternate universe are: Sonic not meeting Merlina and Chip being a regular friend of Sonic that can stay in the open unlike his mainline counterpart.

Sonic Cinematic Universe

The is the alternate universe where the events of the Sonic the Hedgehog Movies and their related media take place, home to counterparts of Sonic, Tails, Knuckles, Shadow, Robotnik, and others. This alternate universes differentiates itself from the Prime World in several ways.

Chaotic Inferno Zone

First introduced in Sonic Rivals 2, the Chaotic Inferno Zone is a separate dimension from the main universe that bears a resemblance to the apocalyptic Crisis City from Silver's future and is only confirmed to have one current inhabitant; Ifrit. The Zone has a dimensional rift that leads to a mysterious mansion in Sonic's world. The key to opening said portal is the 7 Chaos Emeralds. The way to close it is through the switch from a switch within the dimension itself.

Aqua Planet Zone

This is an aquatic planet located within another dimension that is filled with submerged temple-like terrains. It was once used as a base by Dr. Eggman during the events of Sonic Chaos.

Storybook Worlds

These unique type of alternate universes are ones originated of stories, being fundamentally made of texts/manuscripts and narratives, with the the words written down being the story and the world itself. All of the characters are following a set plot as their law and destiny. We have only seen two of this type of reality thus far.

Arabian Nights

The setting where Sonic and the Secret Rings takes place. This reality loosely follows the Middle Eastern folklore One Thousand and One Nights, also known as the Arabian Nights (and being where this universe's namesake comes from). It contains such stories like Aladdin & the Magic Lamp, Ali Baba & the 40 Thieves, Sinbad the Sailor and countless more.

World of Camelot

The setting where Sonic and the Black Knight takes place. This reality follows the stories of the Arthurian Legends, such as King Arthur and the Knights of the Round Table. Besides the living world, there also exists the eternal underworld that is said to be a separate realm from the main one in this Storybook World.

The Spaces Between and Others

Miscellaneous spaces that exist in-between realities, and/or other unique places of the cosmology.

Maginaryworld

The place where all dreams from all other dimensions are assembled and become real, becoming universes/dream worlds shaped by one's desires and aspirations of both positive and negative influences depending upon the person.

Thus the number of dreamworlds would be equivalent to the population of the rest of the multiverse (a 2-B, possibly 2-A structure). Additionally, Cyber Space would also be assembled in Maginaryworld due to the Ancient's dream of preserving their legacy with it and the Egg Field due to Dr. Eggman's dream to rewrite the world with it.

Due to the multiverse creating alternate realities based on possibilities, there would also exist innumerable, possibly infinite amounts of Cyber Spaces and Egg Fields out there. This makes Maginaryworld scale to both realms on a larger scale (Countless, possibly Infinite Low 1-C/Infinite 5-D).

Sleeping Egg Zone

A Dream World created by Dr. Eggman from Sonic Chaos, where he made a base of operations in an island in the skies of it, supposedly shut down after Sonic's success in beating him in there.

Nightmare Zone

Wizeman used Sonic's own dream against him, turning it into a World of Nightmares.

Reverie Haven

A special dream world guarded by a Dreamweaver called Ariem. It houses several dream worlds within itself, with it being said that those deemed pure of heart by Ariem can make their dreams a reality to the real world once a in a millennia.

4th Dimensional Space

The higher plane of Maginaryworld, dreamed into existence by the Goddess of Dreams herself; Illumina. It encompasses all other Dream worlds, seeing them as nothing but flat images on a screen. It is also described as an infinite fourth-dimensional space and has a time component within it.

The totality of Maginaryworld is countless, possibly Infinite Low 1-C (5-D) for being an infinite 4-Dimensional Space with a time component (accepted in this thread) and for containing all the Higher-Dimensional Dreams (like the Egg Field and the Ancients' Cyber Space) within itself.

Hyperspaces

After passing Selection Markers and maintaining light-speed, travelers will reach the Time Warp; this allows them to transcend space-time and thus make time travel possible. On the other hand, experts of Chaos Control have access to a space-time gap; a dimension that grants them space-time movement. This allows the user to hide from enemies while being unable to be interacted with and surprise attack them. Masters of Chaos Control can even use this for phasing or occupying 3 spaces at once.

End of the World

After the revival of the superdimensional being Solaris, it immediately started consuming everything and destroying space-time. Dimensions were absorbed into its body and used in combat, leaving behind a space-time rift. Incidentally, it caused a momentary fractured reality composed of locations from the Prime World's present and future. With the defeat of Solaris and the timeline being reset, all the damage to reality was subsequently undone.

Exception

This is the Extra Zone of the final battle from Sonic Rush, directly stated to be the space between dimensions and a collapsing dimensional rift. This is where Dr. Eggman and Dr. Eggman Nega planned to create an Eggman Land of their dreams that surpasses all dimensions by using the power of the Chaos Emeralds and Sol Emeralds.

Lost Prologue

The space between the Storybook Worlds and the normal reality, which visitors cross before fully entering the Storybook Worlds.

Night Palace

Erazor Djinn's realm in the Arabian Nights Storybook World, a time-shifting palace with a crystal corridor with dream-like properties. It stretches into an infinite space and has maelstroms that act as portals. Parts of the palace exist in the spiritual world, called the Astral Plane. It's an otherworldly space with its own celestial bodies, hourglasses that can teleport visitors in different areas & alter time, certain rooms that change positions, and is connected to the real world. The Night Palace also has a door that can be opened only with the 7 World Rings. In addition to the World Rings, if the bringer is sacrificed, it'll also open up a portal between worlds..

White Space

The main hub world of Sonic Generations and Shadow Generations. It's stated twice to be a dimension between realities, also being timeless void where all of the space time continuum was removed. It holds numerous realities within it; the Prime World; Stardust Speedway, an alternative "Bad Future"; Crisis City, an alternative timeline/an universe "that never was"; even several Special Stages. It is a realm that all realities become once they have been erased by the Time Eater, making it non-existent in nature and lacking all aspects from the rest of the multiverse due to the Time Eater's erasure extending to all of it. Since it can contain all of the normal multiverse erased inside of it, including Maginaryworld, it is 1 layer above it range-wise. It should be noted that this dimension existed prior to the erasure of all reality, and exists independently of Time Eater as it continued to do so after its death.

Doom Zones

The Doom Zone is an eerie dimension that Black Doom created by seizing control of reality and actively twisting it, manipulating, and warping space-time to create a reality for himself. It is another world where the environment is warped into chaotic, non-euclidean shapes, where Black Doom has full control over both reality and gravity to the point where he can infuse the ground, walls, and other objects with dangerous purple energy that can also explode into flame-like obstacles. At its peak, after Black Doom gathered enough strength to complete the Black Moon, it leaked into White Space and gave Black Doom momentary control of it.

Time Eater's Lair

This dimension appears immediately after Modern Sonic and Classic Sonic repair the portal mechanism using the 7 Chaos Emeralds, thus escaping White Space. This and the following dimension remained unaffected by the destruction of all of time and space across all of reality, being "further away" from the rest of the cosmology than White Space itself. Thus, it is "2 layers" above it in terms of range wise.

Infinite Tunnel Dimension

This is the dimension where the battle with Time Eater took place, separate from the previous one and explicitly infinite, where objects from other dimensions may drift here. It is implied to be a time dimension, as flying through it is treated as the same as flying through time itself. This is true despite the fact that the space-time of the multiverse was erased, making it a different and distinct time dimension than the rest of cosmology. Additionally, the Time Eater could alter its flows to even slow down both of the Super Sonics despite showings of Super States being capable of withstanding areas where time is haywire.

Thus the Infinite Tunnel Dimension is 1-C (6-D), due to it being a Hypertimeline that encompasses all the rest of the cosmology.

---

Phantom Ruby Dimensions

Special dimensions created by the virtual reality weapon, the Phantom Ruby.

Egg Reverie Zone

A location first shown in Sonic Mania and Sonic Mania Plus. It is a crystalline void where time is constantly distorted, leaving base characters helpless while in the Egg Reverie by causing them to float aimlessly and without control.

Null Space

A location first shown in Sonic Forces, used in an effort by Infinite to trap Sonic and the Rookie instead of having to deal with them directly. It is a unique world that is said to be "an endless void of nothingness closed off from all other dimensions", where no one could communicate or detect those who were inside of it even when they had technology capable of doing so within the Infinite Tunnel Dimension and Reverie Haven. This makes it distinctly set apart from the rest of the cosmology, as even people who could higher realms couldn't reach here. Later, when used by the Death Egg Robot, it was housing many stars & nebulas inside itself.

Egg Field

The Egg Field is described as an infinite super other-dimensional space, supported by the fact that it could hold several dream worlds inside of it that attempted to bring about Dr. Eggman's "truth" and make it reality. People within the radius of the Egg Field will have false memories implanted in their mind, leaving their existence and history to be freely rewritten by Dr. Eggman's desires.

The Egg Field is Low 1-C (5-D) due to it containing several universes/dream worlds inside of it (making it have a 5-D axis by default), being stated to be infinite, and being inferred to have a different dimensionality from the Prime Universe. A different dimensionality would mean the Egg Field would either be superior or inferior in dimensionality, with the usage of "super other-dimensional" implying must be superior (accepted in this thread).
