Alien Space Bats
"1865 - Alien bats from outer space bring the fruits of their technology to their brothers, because they have heard Elvis Presley on the radio, and think that the south should indeed be free. It ranks slightly higher than a '63 CSA victory. Indeed, I think I will call it "Bats of the South], and make it into a four book trilogy."An Alternate History trope dealing with the divergence of a timeline. If the point of divergence is an extraordinary or supernatural phenomenon, Alien Space Bats are responsible. The phrase was originally coined by the late Alison Brooks as a sarcastic comment on ridiculous alternate history timelines with no realistic chance of happening without some sort of Deus ex Machina as implausibly contrived as bringing in a bunch of Sufficiently Advanced Alien bats. It was only later that it came to mean "explicitly magical or science-fiction what-ifs." Alien Space Bats are in a sense the opposite of a Deus ex Machina: where Deus ex Machina is the introduction of an implausible element outside of the context of the narrative to resolve a plot conflict, Alien Space Bats are an implausible element outside the context of the narrative introduced in order to set up the main plot conflict or setting. The trope may also apply when the point of divergence isn't actually supernatural, but is so wildly implausible that it might as well be that A Wizard Did It. Note that Tropes Are Not Bad: this can and does lead to some excellent yarns, especially if Schizo Tech is involved. Even if the event setting up the plot is fantastic or wildly improbable, that doesn't mean that the character's reactions to it have to be equally unrealistic. However, people who use alternate history to explore the nature of real historical processes may regard Alien Space Bat stories as annoying distractions, or at least as trivial mind games. A frequent mechanism by which Alien Space Bats intervene in human history is Mass Teleportation.note When on a small scale, their intervention may leave people Trapped in the Past. See also Never Was This Universe. Not to be confused with Goddamn Bats, or the Batman from Speeding Bullets, who actually is an alien. Only vaguely related to the movie Lifeforce, which is not AH, but has literal alien bats. Now a verifiable wiki article! That cites this very page on This Very Wiki!

Anime and Manga
- Zipang diverges from history in the wake of the Battle of Midway when a modern Japanese Aegis destroyer is sent back to 1942 by a Negative Space Wedgie.
- The world of the 2003 anime Fullmetal Alchemist' diverged from the normal world when alchemy was discovered. Conversely, the world of the manga Never Was This Universe.
- Interestingly enough in Billy Bat, the titular character, a literal Alien Space Bat, intends to prevent or avoid his world from diverging from our history when it's within his power.
- Watchmen: The exact point of divergence seems to be the presence of "costumed heroes", which isn't too fantastic (none of them have any superpowers), but most of the really major differences can be attributed to Dr. Manhattan, whose appearance marks the point where the course of global politics and history dramatically shift, like the US winning The Vietnam War, or the Soviet invasion of Afghanistan put on hold. For a while.
- Marvel 1602 has everything fairly normal up until the future Marvel Universe suddenly imposes itself on the past.
- One alternative world The Authority fought diverged when blue-skinned aliens arrived in Italy during the Renaissance.
- In the Marvel Universe, Wakanda is one such example. Thanks to a meteor of Unobtainium, the Wakandan people developed advanced technology early, and thus were never colonized by European nations.
- The crashed alien spaceship in Miracleman.
- Über: Shortly before the Fall of Berlin, the Nazis develop superpeople using alien technology. Subsequent developments, in a deconstruction of Stupid Jetpack Hitler, are carefully thought through and extremely depressing.
- The Final Countdown and a few imitators also have some sort of Negative Space Wedgie toss an individual, a country, or a military force back or forward in time so they can change history. The Final Countdown was a Stable Time Loop. Imitators, however, may not include this aspect.
- Possibly referenced in Justice League: Crisis on Two Earths; when Superwoman is trying to decide which alternate Earth to send Batman to, she glosses over one where humanity has "mutated into hideous winged creatures of the night".
- The 1632 series has a small modern American town physically relocated to 17th-century Germany by some process that the author discusses no further than to vaguely say that advanced physics could probably explain it. It does give a tiny bit of exposition about the Space Bats in question (an alien species that thinks of creating temporal anomalies as being True Art), and notes that eventually, they get their just desserts at our descendants' hands for the general hazard their art poses, but that's all in the prologue, after which they never appear again. Eric Flint, the author, explicitly said that he created the Bats in question to allow him to write as many Alternate History novels as he liked.
- John Birmingham's Axis of Time trilogy, inspired by The Final Countdown (see above), depicts a military task force that gets sent back in time from 2021 to 1942 as a result of a failed experiment on one of the ships in the task force.
- Without Warning and its sequel After America also by John Birmingham, set in 2003 and after, features a wave of unknown energy that causes the population of most of North America to be suddenly disintegrated. Other, non-primate animals are either unaffected or destroyed on a seemingly random basis.
- In Harry Turtledove's The Guns of the South, the Confederate States win The American Civil War because time-traveling South Africans give them AK-47s.
- Ravage uses an identical premise, but falls under the category of future rather than Alternate History, as it takes place in the 21st century and was written in 1943.
- The (nowadays less-known) likely progenitor of the "CSA victory" variation of Alternate History, Bring the Jubilee by Ward Moore, utilizes the trope with a twist. The basic premise is a classic example: history is changed by a time traveller affecting one small event (accidentally, in this case). The twist is that we're shown the Alternate Universe throughout the novel, while the actual time travel experiment with its consequences occurs near the end - the reason being that in-universe, the historical reality was a Confederate victory (for wholly mundane and plausible reasons) and the Alternate Universe of a dominant CSA is the actual reality in the novel. The result of the time traveller's actions is the emergence of an alternate timeline in which the USA won - i.e., our real world is the alternate reality in the novel's universe.
- The Belisarius Series is a good example; its divergence is the result of a Terminator Twosome of warring AIs FROM THE FUTURE. Link was sent by a group of Master Race-type purists to prevent a future full of what they see as Transhuman Treachery, while Aide was sent by kind, gentle Transhuman Aliens (of the Space Whale persuasion) Link is trying to Ret Gone.
- The major point of divergence in the Wild Cards franchise is the outbreak of the eponymous virus on Earth, which bestows superpowers on its victims (that is, if you can avoid the horrible death part).
- In an intentional homage to this trope, Ken MacLeod's Learning the World is set on a planet inhabited by actual Alien Space Bats — to whom humans are the mysterious alien visitors who change the course of history.
- Ben Jeapes' children's novel The New World Order diverges in the middle of the English Civil War when Neanderthals from a parallel universe invade and steamroll over both sides with roughly World War I level technology. Also they have a few wizards.
- Kim Newman's Anno Dracula series and Neil Gaiman's A Study in Emerald have respectively Dracula and HP Lovecraft's Old Ones as rulers of The British Empire instead of Queen Victoria. In Newman's, Dracula does this with Victoria's own approval, as her regent.
- SM Stirling is noted for this trope, probably because he was a regular reader of the newsgroup where the term was coined:
- The Draka has the initial divergence of American and French royalists being sent to the fictional colony of Drakia. It then has a number of others, such as the existence of an incredibly complete cache of classical literature in Western Africa, and the spontaneous appearance of several technological advances in a culture with little incentive to have them. For example, they send steam-powered warcars to help the Confederacy, and have enough dirigibles to launch an air raid that kills 50,000 people against Russia in the 1880s. They also have atomic bombs by 1944, but so does the United States.
- Island in the Sea of Time starts with the Event: Alien Space Bats sending Nantucket (and a big ellipse of ocean surrounding the island) back in time to the Bronze Age.
- The Emberverse novels: in the 1998 from which Nantucket was taken, the same Alien Space Bats cause all industrial-level technology to become useless. Lampshaded as some of the characters explicitly use the term "Alien Space Bats" as a label for whatever unknown force caused most human technology to suddenly stop working.
- The Sword of the Lady, these particular Bats are revealed to be the Mind, essentially the Jungian Universal Subconscious having an argument with itself.
- The Lords of Creation series is set in an alternate history where Mars and Venus are habitable (having been made so centuries ago by the eponymous advanced alien race, for reasons not yet revealed).
- Harry Turtledove's World War/Colonisation books - the point of divergence is aliens invading during World War II.
- In the Roger Zelazny book Roadmarks, the time-traveling main character keeps attempting this to fix Thermopylae (in the story the Greeks lost) but the Time Police keep catching him.
- Elizabeth Bear's New Amsterdam has alien space bats in the form of magic warcraft used by Native Americans, preventing Europeans from settling the Americas except spottily along the coasts.
- Thor Meets Captain America by David Brin has Nazi Germany essentially winning World War II because they were able to summon the Norse gods to fight on their side. They ultimately lose it all when Loki - whose titles include "The Ever-Contrary" - betrays them. The trope was used to make a point here: this was the most plausible scenario the author could think of that would have the Nazis winning.
- Steven White's Saint Antony's Fire starts off with Ponce de Leon discovering the wreck of an interdimensional UFO, quickly followed by the resurrected aliens allowing the Spanish Armada to successfully invade England.
- Naomi Novik's Temeraire series is set in the Napoleonic Wars in a universe where dragons exist and are widely used by humans, especially militaries. The Alternate History elements are not immediately apparent, but there are numerous key differences; the Incans, for instance, are a major world power because of their dragons, and the Chinese, far from being in decline and getting bullied by Western powers, are one of the major players in the war as both sides try to enlist their aid, or at the very least keep them from joining the other side.
- Taylor Anderson's Destroyermen series has the Squall, a bizarre, recurring storm that has repeatedly transferred ships from our Earth to an alternate timeline where the K-T extinction event did not occur.
- In John Birmingham's Without Warning, just before the 2nd Gulf War, a strange energy bubble appears over North America and kills all primate life within it's premises. One of the consequences is Israel nuking the Middle East and New York City being attacked by pirates (many of them being refugees from the Middle East).
Live Action TV
- A few Sliders episodes fell into this, with worlds where physical laws permitted magic and wizardry and dragons, whereas other worlds were For Want of a Nail. Still other worlds the Sliders visited combined these aspects. Interestingly, only one world had an event that fits the "alien" bit. According to the show, all those alien conspiracies on other worlds are actually true. The only difference on this world is that the government went public with First Contact and established open trade with the Reticulans, resulting in many technological advances (including a virtual panacea, anti-gravity, and a manned mission to Mars). Disappointingly, the characters themselves don't actually get to meet any aliens. The best they get is a human who looks part-Reticulan thanks to a side effect of the panacea drug (his blood is also green).
- Alison Brooks introduced the alien bats to soc.history.what-if in her Alternate History spoof Irony And Steal. Here, the bats descend on Manchester, England at the start of the Napoleonic Wars, having learned how to speak English from listening to future radio broadcasts, and supply tanks to Britain with which it can defeat France at El Alamein. Silliness ensues, including the Russian Czar marrying a bat, dirigible arms races, Lenin becoming a baseball player, and alien mutant ninja turtles replacing the population of Australia.
- On the Spacebattles forums, an entire section of the site is dedicated to what they call "Random Omnipotent Beings," or "ROBs" doing precisely this, starting off many role-play threads.
- As a general rule, the ones that actually cause the implausible scenarios are referred to as "Bastard Random Omnipotent Beings", or "BROBs"
- The amount of Willing Suspension of Disbelief required to believe the point of divergence in Soviet history that sets up the What If Klitschko Special is sufficiently high to drive that story into ASB territory—-especially since it assumes that the events of Rocky IV are canon.
- The GURPS "Infinite Worlds" campaign has two major opposed alternate-reality-jumping factions (Homeline, our world circa 2027 if paratemporal technology had been invented in 1994, and Centrum, a recovered post-apocalyptic One World Order of Straw Vulcans with similar tech) often act as this in other timelines to further their own interests (which right now is mostly screwing up the rival faction). The players are probably going to work for one or the other.
- Shadowrun has two small ones and one big one;
- In 1999, the Supreme Court grants certain major corporations the right to form private armies as "ex post facto" justification for ending a vicious food riot with a massacre instead of permitting the rioters to accidentally start an outbreak by eating hazardous medical waste. It's implied that the "Seretech Decision" was planned in advance from riot to lawsuit, because it's kind of stupid to transport hazardous medical waste through Manhattan during a food riot...
- Especially because the same year, the NRC was forced to give another corporation its own nuclear power plant rather than be accused of graft. And the corporation was able to spin an ecoterrorist attack on the plant into nationhood(the "Shiawase Decision") by saying they'd have been able to protect the place better with mercenaries instead of local cops. And an attempt by the ecoterrorist group to clear their name is interrupted by a bombing believed to be the first shadowrun.
- The real ASB is when The Magic Comes Back in 2011...
- Deadlands: The Weird West starts with a vindictive Native American shaman unleashing Sealed Evil in a Can, which leads to all sorts of weirdness, like the Battle of Gettysburg being interrupted by zombies, and a huge earthquake splitting southwest California into a series of canyons lined with a new mineral called "ghost rock", which is basically coal that burns more efficiently but also makes creepy noises. And that's just for starters...
- In Failbetter Games' browser game Fallen London, Victorian-era London was literally stolen by bats. And it turns out the Masters of the Bazaar are literal Alien Space Bats. Makes you wonder if it's a deliberate reference to the Trope Namer, doesn't it?
- The Resistance series is based entirely around this trope, where the alien Chimeras arrive in The Tunguska Event of 1908. In 1921, Russia initiated a communications blackout with the rest of the world, and built a wall against its European border called the "Red Curtain". In December 1949, the Chimeran forces invade mainland Europe. The first game starts with their invasion of England in 1951.
- The backstory for Dawn Of Victory, a mod-in-development for Sins of a Solar Empire, is inspired by the World War series in that it involves aliens invading during WW2 and proceeding to kick everybody's ass, except for a few isolated victories. Then nukes are developed and used, pushing the Scinfaxi to the Southern Hemisphere. History then proceeds similar to ours in the Western world, except there are three superpowers: USSR, Germany, and the Democratic Federation.
- In Robo Aleste, the arrival of a mysterious foreign derelict ship introduces to Sengoku period Japan firearms, airships and Humongous Mecha.
- Paradox Interactive is normally known for creating highly-detailed, well-researched historical Real-Time Strategy games that try to err on the side of plausibility in modeling the setting. This is why several fans were, to put it mildly, taken by surprise when they launched the Sunset Invasion minor DLC for Crusader Kings II, which introduces a massive invasion of Western Europe by a technologically-advanced, disease-spreading Aztec Empire.
- As of 2010, Guilty Gear's discovery of a physics-defying energy source that kicks off a genetically engineered monster apocalypse and turns the whole world into the cover of every metal album ever has officially become this.
- Wolfenstein: The New Order has Nazi Germany beating back the invasion of Normandy in '44 and going on to win a WWII that lasts until 1948 through the use of extremely advanced technology, decades ahead of anything the Allies can muster. They then proceed to colonise the Moon by 1951, and spread their lebensraum across 75% of the entire world by 1960. Early in the game, it's revealed that the reason for this was General Wilhelm "Deathshead" Strasse discovering a secret cache of amazing, near-magical technology early in the war, and then reverse-engineering it to create unstoppable war machines. The irony, of course, is that the sect who made this technology— the Da'at Yichud— is Jewish.
- In Futurama, a jerk from the XX century who was living in the XXXI century and who made time travel, messed with a signal during the American Revolutionary War, that led to the British victory. When they return to the XXXI century, the US is now British, it has always been British... at least, until they made another trip to Set Right What Once Went Wrong.
- A similar timeline change occurs in Big Guy and Rusty the Boy Robot, when the Big Guy Powered Armor ends up in the American Revolutionary War, until a British soldier discovers it and pilots it to defeat America, also forcing Rusty and the Big Guy's actual pilot to Set Right What Once Went Wrong.
- In Steven Universe, at some point before humans developed agriculture, the planet was colonized by an alien species called Gems, who eventually fought a civil war. This has clearly affected humanity's development, but it's pretty subtle and unclear of how exactly. There seem to be vast tracts of land which are now uninhabitable by humans, either because they can't contain life or are running rampant with Gem monsters or technology. Florida in this universe is an island, European colonization of the Americas appears to have occurred hundreds of years later, and art throughout history seems to have been influenced by the Gems' presence.
