Crossover Universe TheoriesEdit

CU Alien CreaturesEdit

The Crossover Universe has many known alien species inhabiting its cosmos, but some seem quite similar to others. While iffy, these alien races could possibly share some connections or might even be one-and-the-same.

CU Fictional CountriesEdit

CU Fictional Island NationsEdit

CU Fictional IslandsEdit

CU Unnnamed IslandsEdit

CU AtlantisEdit

These are all the connections to the legend of Atlantis I was able to find in the CU.

  • Atlantida - The titular ruined city is a remnant of a post-flood Atlantean colony.
  • Atlantis: The Lost Empire - The remnant of Atlantis' survival was the result of the Heart crystal shielding the city.
  • Bothon
  • The Fall of Atlantis - In the days before Atlantis sank, the opposing orders of magicians, the honorable Priests of the White Robe and the wicked Black Robes, had a hand in its eventual downfall.
  • They Found Atlantis
  • The Magician’s Nephew - Andrew Ketterly was given an Atlantean box by his godmother, who might've been descended of the Fae.
  • Cthulhu Mythos - Klarkash-Ton was an Atlantean priest of Tsathoggua. The Shining Trapezohedron was kept at Atlantis when it sank.
  • The Illuminatus! Trilogy - Atlantis is supposedly the birthplace of The Illuminati.
  • Indiana Jones and the Fate of Atlantis - This Atlantis is really a colony made by descendants who created orichalcum orbs to power a machine that would turn them into gods to prevent the flooding from continuing.
  • King of the World - Jimgrim battles Dorje, who has discovered the scientific secrets of Atlantis and is using them in an attempt to conquer the world.
  • The Judex Codex - Atlantis is conflated with Numenor.
  • Kull - Kull is one of the former Atlantean warlords who escaped the flooding.
  • Lensman - The Arisians provided the people of Atlantis with Lenses and advanced technology. The Atlantians had developed jet aircraft and nuclear weapons, the latter of which lead to its demise. Influenced by malevolent alien forces intending to nuke humanity, the flood was the result of the missile being knocked off-course by a heroic Atlantean and hitting a faultline.
  • The Lord of the Rings - Numenor is implied to be the original name for Atlantis. The island was flooded when the city was corrupted by the being who would later be known as Sauron; the flood was the result of the Undying Lands being removed from the Earth.
  • The Maracot Deep
  • Lost Treasure of Atlantis
  • The Ship from Atlantis
  • Namor - Namor is the hybrid offspring of Queen Fen, the ruler of one of Atlantis' surviving underwater colonies.
  • The Amulet - The children time-travel to Atlantis just as the flood hits.
  • The Space Trilogy - Merlin is descended from the magicians of Numenor (a.k.a. Atlantis).
  • Skull-Face - Kathulos is an Atlantean necromancer and magician.
  • Sun Koh - Sun Koh is a former prince of Atlantis and a survivor of the flood. According to him, Atlantis is destined to rise once again.
  • Twenty Thousand Leagues Under the Sea - Captain Nemo knows the location of the sunken Atlantis' ruins.

Those that were believed to have been of Atlantean origin but were since disproven are listed here.

CU FairylandEdit

The elves and other fairy creatures of the CU are shown to inhabit an otherworldly realm or dimension parallel to Earth's. These are the known locations and names it goes by.

Possible linksEdit

CU Solar SystemsEdit

The League of Extraordinary GentlemenEdit

It's come to my attention that most of my efforts in expanding the Crossover Universe have been dismissed due to creative differences with the heads "running" the fictitious world. Despite my efforts in making sure these sources matched the regulations they've established for it, they seem opposed due to some minor aspects that they can't overlook (despite them doing the exact same with others). Rather than try and fight them, I instead opted to preserve them here as part of my letter of resignation. It's been fun working on this project, but I guess all paths must split at some point. - LogiTeeka, 7/15/20

My Take on the CU Future EventsEdit

While these sources appear to be conflicting accounts of what the future of the CU holds, I think there might be enough room to wriggle in some (if not most) of the other future accounts into the official narrative. I mean, at the time I'm writing this, we're already on the cusp of the 2020s and it's already looking nothing like how Star Trek described it. So rather than forcing everything to adhere to the real world, why not let the CU take its own course in history?

Pre-Space TravelEdit

In the Star Trek: Voyager episode Future’s End it is shown that Henry Starling has had access to 29th-century technology from as far back as the 1960s, which he has been using to push Earth’s software and hardware knowledge far in advance of where such knowledge should be. This, more than any other aspect of Star Trek‘s timeline, is the crucial point at which we ought to separate from our own history – the “real” history of Earth.

It is with his mangled understanding of 29th-century technology which allows both the creation of the experimental security drones employed at the Park Plaza Mall in the early/mid-80s, the T-1 and – eventually – the technology necessary for the integration of mechanical elements into Officer Murphy.

Granted, these were not the only examples of advanced, self-aware robotic technology existing in the CU. You have Dr. Coppelius' gynoid Olyipia, the artificial synthetic lifeforms engineered by Rossom’s Universal Robots Inc., and the android replicants created by fed-up husbands in Stepford who sought to replace housewives. The most famous of which was a creation of Nickola Tesla, known to many as “Atomic Robo”. Most of these Pre-Cold War robots were either wind-up automatons or nuclear powered, as advanced power cells had not been completely understood.

While many of the elements of the future technology were able to be reverse-engineered by in-house scientists, some of the advancements were so esoteric as to preclude the direct understanding of the way they operated. Hill Valley resident scientist and inventor, Dr. Emmet Brown, would wind up creating the flux capacitor - one of the key components to the warp drive engine - for his time machine and, following a series of hectic time-traveling shenanigans, would later found the Institute of Future Technology. A significant amount of research into matter transportation was developed by François Delambre during the Cold War. His interpretation of the technology would result in his untimely death and his research would not be continued until Dr. Emory Erickson perfected the means by which to transport living tissue.

By the 1990s, with advances far outstripping "real" history, the US government requests Starling’s Chronowerx Industries assistance in coming up with solutions to some of the problems it is facing after seeing the valuable technological advancements being made. In 1992, HAL 9000, Production Unit 3, Artificial Intelligence Computer System becomes operational at HAL Communications plant in Urbana, Illinois. Meantime, following the plans laid out by the government supercomputer Colossus for a larger computer complex, Cyberdyne Systems develops another AI to interpret massive data input now being collected by the military branches of the US intelligence community, leading to the creation of a satellite defense program dubbed 'Skynet', which is one of the primary reasons for future problems.

While no longer as intense as it was back during the Cold War, the space race between the US and Russia continues with the ever-increasing development of space colonization. In the mid-'90s, the first United States Lunar Base, Clavius Base, is successfully constructed by the U.S. Astronomical Engineering Corp and the Discovery 1 exploration spacecraft begins construction in utmost secrecy. But shortly following the first day of the third millennium, a magnetic disturbance on the lunar surface leads to Lunar Orbiter 10 uncovering a prehistoric alien artifact near the crater Tycho known as “Tycho Magnetic Anomaly-1”. Meantime, experiments in secure space travel and habitability are carried out at the prestigious Gizmonic Institute. However, safety concerns were raised when a group of sadistic scientists shanghaied an unsuspecting janitor aboard their experimental spacecraft, the Satellite of Love, in an effort to examine the claustrophobic conditions of spaceflight.

However, it is around in the 1990s where we find things take a turn for the worse. Spurred on by the existence of beings living on other planets, more of the future technology is plundered to create the ground-work which will lead to the genetically-engineered Khan and his followers. This is also around the time that things start to go seriously wrong with society. The slip into anarchy begins with a few minor problems, soon lead to rampant anarchy in the streets as people release the tension created by the existence of genetically superior individuals being created. It is from these dark days that the Eugenics War erupts into a full-blown war.

The Fallout From The Eugenics WarsEdit

In 2020, the outbreak of COVID-19 winds up creating massive civil unrest across the world. The Deep Space Nine episode Past Tense shows what has happened in the US by the 2020s, with large sections of cities cordoned off to provide housing for ‘undesirables’. Some cities, such as Detroit, prefer to deal with their social unrest by handing over their policing to corporations, which results in the creation of the RoboCop program. Due to the rise of greenhouse gasses in the atmosphere and unchecked urban growth, life begins perishing and the plankton population drops, propping popular food companies to use human remains as resources to feed consumers. Other locations fall into complete unrest as “entertainment” such as The Running Man, Rollerball and other shows allow the population to be kept entertained and (largely) kept under control.

It is also around this time that the full horror of what Skynet has become is made clear. By 2026, WWIII Breaks Out Between the US/UK and ECON, likely triggered by Skynet unleashing its nuclear arsenal. Taking refuge in the stars was not the sole preserve of the genetically engineered super-soldiers, as others decided to abandon Earth. A devastated New York city is later rebuilt under the new name 'Metropia'. However, this would only mark the beginning of the horrors that were to come.

The presence of Starfleet's Time Police and/or Temporal Investigations seems to suggest that they began as a much simpler organization. It makes a sort of sense that the events of Timecop in could be the shaky beginnings from which the Federation would spin out its’ time protection force.

Zefram Cochrane’s warp flight in 2063 brings the attention of the Vulcans. And with the assistance of Vulcan technology, the rise of Skynet's machines is prevented. From this point on, all research into advanced robots is banned in an international treaty. This results in the secret creation of the synthetics, or artificial people - which later developed into the Soong-type Androids.

But even after their contact with the Vulcans and their victory against the machines, the Earth is still suffering from the nuclear aftermath of WWIII. By 2079, most of the Eastern United States are part of a large territory known as Mega-City One. To combat the increasing crime wave, the authoritarian Justice Department employees militaristic enforcers called Judges to carry out litigation.[1] Meanwhile, in Asia, fortified cities like Neo Seoul are constructed to protect recovering humanity from nuclear fallout. In Britain, the wealthy descendants of Graham's inheritors, calling themselves the White Council, use their money to buy the industries and political entities to establish a vast economic world order, establishing a plutocracy and sweeping away parliament and the monarchy. But their attempts were thwarted when the comatose Graham reawoke in 2100 and aided the abused working class in fending off the White Council's incursion.

By 2100, after several previous manned missions to Mars, humanity finally begins to colonize the red planet. But even with the invention of Zefram's warp drive, humanity still employs Sleeper (hibernation) Ships to make long-distance space travel seemingly quick. The technology would not become obsolete until around 2118. [2] As Picard points out in the TNG episode The Neutral Zone, cryogenic stasis had long since been abandoned in the 23-24th Centuries, but it had been employed routinely in the early days of interstellar travel. While practical, many catastrophes resulted from the use of Sleeper technology. The ill-fated Discovery 1's expedition to Saturn in 2001 resulted in HAL 9000’s malfunction and the death of four crew members. Later analysis by NCA “Project Jupiter” Review Board showed that the decision by the Chairman of the National Council of Astronautics (NCA) to keep the mission a secret from the primary crew was what caused the programming conflict within HAL due to the computer’s basic programming that did not allow it to lie or mislead. In 2122, one of the Wayland Industries mining vessels was operating in deep space when it encountered an alien life form which killed the entire crew save for its’ Warrant Officer, Ripley. These disasters among others resulted in the abandonment of cryogenic chambers in favor of tighter controls being made to the design of astronavigation systems.

Post-United FederationEdit

But as is often the case with empires that last for too long, the Unified Earth government eventually starts to feel the weight of maintaining control over the populous of the planet. By the 2400s, the government began a drastic reformation by forcibly impose their new ideologies on Earth's populations, forcing citizens to meet certain quotas of consumerism to stimulate the economy. When met with opposition, the governments responded with violence and massacres of dissenters. When that didn't work, they began a peaceful campaign of change. This campaign included the closing of museums, the suppression of almost all literature published before 2058 AD, and the destruction of the few historical world monuments that had survived the Nine Years' War. By 2540, the World State is fully established and almost all the people of Earth are citizens.

By the year 2688, society became a peaceful utopian society based around the 700 old songs of Wyld Stallyns’ Bill Creston and Theodore Logan, who the masters sent the Time Lord ‘Rufus’ to guard and protect. But like all periods of peace, this gave rise to many conflicts and attempts at breaking down the pillars of this new utopian society. One of the more infamous agents of the rival party was Chuck De Nomolos, who stole one of the time-traveling phone booths in an effort to assassinate the Wyld Stallyns and replace them with synthetic androids.

Despite mankind’s slow recovery following the conflict, humanity’s populations on other planets and colonies fare much better. In 2762, the Galactic Patrol (established by mankind’s distant ancestors, the Arisians) began recruiting Lensmen; the first title of which is given to the fine-bred Virgil Samms of Earth, which by that point was now recognized as ’Tellus’. This effort could be seen by some as a replacement for the earlier Green Lantern Corp.

Lensman - 2801-2900

By the year 3000, humanity has become complacent, and many worlds have left the Federation because of its Human-centric nature. The Ferengi become the dominant power in the galaxy and make money by spreading the Bajoran religion and making Bajor into a major place of pilgrimage. The Vulcans reunify with the Romulans, the Cardassian and Klingon societies have evolved into more mystical and less warlike cultures, though the Klingon Empire is expanding once more (but on good terms with the Federation). Starfleet is stretched thin and many of its ships are outdated. A new enemy called the Scourge attack and destroy the USS Sojourner and two colony worlds. The only survivor is Lieutenant Commander Alexander Kirk. The authorities refuse to believe his story, a state of affairs that causes Vulcan, Bajor, and Betazed to leave in disgust at the corruption of the UFP, leaving it with only twenty systems under its control.[3] The Scourge eventually wind their way to Earth by 3069 and unleash a series of devastating attacks that wind up terraforming the Earth into an ocean planet. Simon Wagstaff is one of the few survivors to flee off-world when he happens upon an abandoned Chinese spaceship, the Hwang Ho.

The Chronic Argonauts - 4003

Around 5000 AD, the Breach opens up in the Pacific Ocean, tearing a portal to the Anteverse, the homeworld of the Precursors, and the Kaiju.[4] After eons of slumber, Cthulhu finally awakens and establishes his reign of madness with the Deep Ones attacking the human population. In response, the Tsan-Chan Empire Dominates the Earth.

  1. Judge Doom has fought both Xenomorphs and Yautja as well as a time-displaced Batman, providing a strong linkage to the CU.
  2. Star Trek originally had the date set at 2018, but I highly doubt that is an accurate time placement since humanity had no need of Sleeper Ships before spacetravel became commonplace by that point.
  3. This narrative was the plotline for the unproduced series Star Trek: Federation, which I decided to include since it provides a hint of what might've become of the Federation in the distant future.
  4. The Ogdru Jahad's crystal prison is seen the Anteverse in Pacific Rim. Godzilla is implied in the film to have originated from the Breach.
  5. The estimated date is recorded at 20000000000, but this placement seems unlikely, so it's most likely a miscalculation.
