Page Type: trope

Serpentine: You think you can just walk into this conflict, don't you? Well, I have news for you... This isn't your fight!
Lilac: It was the moment you brought it to our homeworld!

Factions 1 and 2 of World A have been fighting for eons. Then out of luck, Faction 1 ends up finding World B, which was completely unrelated to the war and had no involvement whatsoever. Faction 1 might send spies in the world becomes useful to them. Faction 2 later learns of World B's existence and sends its forces there, turning World B into another battleground for World A's war.

In a situation like this, the inhabitants of World B would be taken completely by surprise and must find a way to deal with this unexpected twist in events. Some may take sides among the various factions. Others may try to become intermediaries become it consume their own world. And there are those who want to become a third faction to drive out both.

The warring factions don't exactly have to be Trapped in Another World either, they just have to fight each other on World B, which had absolutely had nothing to do with them until now. The war could be either secretive or full-scale, old or pretty recent. The trope does not count if World B had public knowledge of Factions 1 & 2 and got involved beforehand, which would just be a neutral country being attacked by both of its neighbors. However, it can apply to an isolated island that gets invaded by two or counties elsewhere.

Compare Alien Invasion, which is a war between an invading world and the invaded. Contrast Truce Zone, an area where warring agree not to fight, especially if the areas are neutral, have nothing to do with the war or are too important to risk any damage.

Examples:

Anime & Manga

  • Aura Battler Dunbine is a very unique isekai series not just by preceding most of the modern hits of the genre, but also having the alternate world of Byston Well undergo a Mass Teleportation into the modern world a.k.a. Upper Earth. Considering the first time Aura Battlers appeared, the Upper Earth military attacks first, resulting in the annihilation of most air forces, the liberal use of nuclear weapons, and up to total destruction of entire cities including national capitals. Drake later takes advantage of his affiliation with those from the United States (i.e. Shot Weapon and Todd Guinness) to acquire a staging ground for conquering the rest of Upper Earth. At the same time, one of Drake's more powerful allies indiscriminately attacks cities in Europe, causing the continent's nations to cast their support for the heroes.
    • What really separates this apart from other series is how Aura is at least ten times more potent in Upper Earth than in Byston Well. Shou witnesses first hand that small missiles only made for destroying Aura Battlers have the power of mini-nukes, killing over a million people in Tokyo, and Aura Barriers are able to shake off nuclear weapons like nothing. The whole final arc is about the rebels stopping Drake before the world turns into a desolated wasteland.

Comic Books

Fan Fiction

  • Although not a war, Angelic Resonance starts with the Time-Space Administration Bureau's pursuit of the Huckebein going horribly wrong and throws them in the Empire of Misurugi. The Bureau quickly pick up the First Princess and her maid abroad while the Eclipse-infected killers go on a rampage. Then Leonard's Amalgam faction gets involved.
  • Some stories of The Conversion Bureau stories have the war between Earth and the Solar Empire Equestria spilling over into canon Equestria.
  • Some Gate fics or inspired fics have several gates opening to the Special Region from Earth. The result is trope as the nations or factions war with each other, but take the fighting to the Special Region with different policies over how to deal with the inhabitants.
  • In Weight of the World, the people of Remnant have been at war with Salem and her Grimm for millennia. Atlas, a Kingdom of Remnant, discovers Earth's existence and secretly sends spies to the planet to see if its people and resources can be useful to their side. A decade later, an Atlas traitor tells Salem about Earth's existence. Out of the desire to kill any and all potential hosts for Ozpin, Salem sends hordes of her Grimm to Earth, including Spawner-types, which spawn an endless amount of Grimm. This pulls Earth into Remnant's war. Earth is not happy to be dragged into another world's war, and the Terran death toll rises so much that some parties consider using nuclear weapons on Remnant in order to kill the Grimm at their source and save their world.

Comic Books

  • The plot in Birthright is kicked off when teenager Mikey Rhodes is whisked away from Earth to Magical Land known as Terrenos because he is prophesized as a chosen hero that will liberate it from the brutal and unstoppable tyrant God-King Lore. Unfortunately, he witnesses so many horrors of war as a Child Soldier that ends up cracking and makes a deal with Lore to be returned home. To make matters worse, it's later revealed in the series that he never was The Chosen One in the first place, and he was forced to participate in a conflict that never concerned him.

Film

  • Transformers is often about the Autobots and Decepticons fighting on Earth, with humans being caught in the middle.
    • The Michael Bay-directed Transformers series has humans repeatedly change sides during the war. The first couple movies have them work alongside the Autobots after constant attacks by the Decepticons, even forming the N.E.S.T. government organization. The next couple movies show some humans turning on the Autobots, from those wanting them to leave and take the fighting someplace else to outright helping the Decepticons. The last few movies feature them hunting down both groups with only a few remaining loyal to the real heroes of the story.

Literature

  • In Animorphs, the Yeerks were invading Earth anyways to obtain hosts, but it ends up the strategic battlefield for the Yeerk/Andalite war.
  • Good Omens: Earth is prophesied to be the site of the final battle between Heaven and Hell, which would have the unfortunate side effect of ending the world. Defied by the Anti Anti Christ Adam, who tells the assembled angelic and diabolic legions to pack it in and go somewhere else.
  • In Invasion: Earth by Harry Harrison, a group of alien ships requests aid from Earth against an incoming group of invaders. There is a big twist at the end.
  • "The Liberation of Earth", a classic short story by William Tenn has two alien species "liberating" Earth from each other as part of a galactic war. They leave the planet wrecked nearly to pieces, and the whole thing is barely a footnote for them.

Live-Action Television

  • The V features a conflict between the titular Visitors and a rebel group known as Fifth Column who want save humanity and other races from being devoured. It is mentioned that said Visitors are currently at war with other races as well.
  • Falling Skies, like the V example, has the Earth suffer from an Alien Invasion, which then evolves into a battleground for other alien races working for or against humanity.

Video Games

  • Freedom Planet: Torque points out that the war his team has been putting up with against Brevon's army has resulted in many innocent worlds being destroyed by Brevon's hand, and the reason he and Brevon came to Avalice is for the kingdom stone. Brevon wants the kingdom stone for his army, while Torque wants to ensure that Brevon doesn't get it by any means. Upon hearing Torque's story, Lilac, Carol, and Milla all agree to help him stop Brevon, because they consider Torque a friend and since their planet is just as much on the line.
  • Iji opens with an Alien Invasion of Earth by the Tasen, but it soon turns out that they're only here because they're on the run from the Komato, who have long been waging a war of extermination against the Tasen.
  • The Sid Meierís Alpha Centauri expansion "Alien Crossfire". Two ships from warring factions of an alien race, the Manifold Caretakers and Manifold Usurpers, crash land on the same planet being colonized by humanity's remnants.
  • Starcraft starts as one of these at the beginning. The Terrans were the only known sentient beings in the Koprulu sector with the Confederacy as the primary superpower. Then the Zerg and Protoss show up, who fought each other for a longer period of time and brought the war right to their doorstep.
  • Super Robot Wars X has the X-Cross fight sandwiched on a two-sided front, with one being the Empire of Misurugi waging war on the inhabitants of Al-Warth. How does such a nation with abysmal weapons besides its Bug-inspired drones do that? They summon people from existing wars (hence the Mariemeia Army insurrection, Zogilia-Free Pact Alliance War, all the conflicts within Gundam: Reconguista in G, with some Universal Century antagonists for good measure) and recruit the more antagonistic factions to do the fighting for them.
  • The premise of Xenoblade Chronicles X starts with Earth getting blown up in the crossfire of two alien forces. While one of the two factions actually was trying to kill off humanity, the planet was blown up by accident before they had a chance to actually destroy it. Humanity just barely managed to escape, and most of the fleeing ships didn't even make it out of orbit.

Tabletop Games

  • Dungeons & Dragons: The Plane of Hades is the primary battleground in the unending Blood War between the devils of the Nine Hells and the demons of the Abyss. Hades' native Yugoloths have mostly relocated to a different Plane.

Web Comics

  • Kill Six Billion Demons: The Universal War raged across 777,777 worlds as a group of insane God-Emperors with dreadful Enlightenment Superpowers discovered The Multiverse, laid claim to entire planets, and then ravaged each other's territories. Those that survived the Conquest didn't fare much better, being ruthlessly exploited for their resources.
    White Chain: Having cut God's work, the Demiurges began to open all the multiverse. The Second Conquest was long and brutal. ...At first, they pretended their war was civilized, but then their singular hunger for dominion consumed them. And they went mad. Worlds burned, Allison. They burned.

Western Animation

  • The Justice League second season finale has Thanagarians destroy an invading Gordanian warship and offer their assistance in building a shield generator against future attacks. Then it turns out their plans are a bit different and more... desperate.
  • Occurs with somewhat increasing frequency in Star Wars: The Clone Wars because of Palpatine's machinations forcing many of the neutral planets to side with either the Republic or the Separatists. But, most prominently in the episodes Jedi Crash and Defenders of Peace in Season 1, when Jedi Knight Anakin Skywalker, his padawan Ashoka Tano, and Jedi Master Aayla Secura crash land on Maridun. When the native peaceful Lurmen agree to aid the grievously injured Skywalker, the Separatists arrive not long after to claim the planet as their colony. Despite the combined efforts of the Jedi, their Clone Troopers, and the native Lurmen successfully destroying the Separatist forces, the Lurmen ultimately agree to join the Republic.

It doesn't matter whose war it is (i.e it can be ours), as long as it's in a place the warring sides aren't native to?

Can it count, say, armies of Country A and B fighting in Country C?

Mar 11th 2019 at 7:04:54 PM

@4tell0life4 Not exactly. If it were true, the way I see it, Country A and B must come from World A, while Country C that's caught in the middle must come from World B.

^^ Can't it happen in a single world?

I'm asking you to think about the scope again.

Mar 11th 2019 at 8:09:56 PM

Yes, it can. Though the way I see it since it comes from "another world" is that Countries A and B have to completely different from Country C. And must be unaware of the two nations or at least the war until it all comes to their doorstep. The trope does not count if Country C knew and got involved beforehand, which would just be a neutral country being attacked by its neighbors.

An example of a valid example would be an isolated island suddenly becoming the battleground from two or more powers of another continent. Like if (which sort of happened) the European power were at war with each other and fought within the American colonies, which had nothing to do with it until that point.

Comic Books

  • In Saga, the long-running war between the planet Landfall and its satellite Wreath has been outsourced to other planets, as the leaders of both planets quickly realized that they could not wage war on each other's worlds without causing drastic environmental effects on their own.
  • In Runaways, Skrull prince Xavin threatens to invade Earth if Karolina refuses to help them end the war between Xavin's home planet and Majesdane, the planet from which Karolina's parents hailed.

Film Live Action

  • The plot of Valerian And The City Of A Thousand Planets is kicked off when a United Human Federation fights a battle on a planet that was assumed to be uninhabited, leading to the planet's inhabitants, who had no involvement in the fight, being slaughtered.

@Strix How is the Valerian one an example? Isn't that just an Alien Invasion but with humans? Please be more clear about what caused them to strike the planet.

"The trope does not count if Country C knew and got involved beforehand, which would just be a neutral country being attacked by its neighbors."

That sounds like an idea that is tropeworthy and should be put in this draft.

Mar 14th 2019 at 8:03:45 PM

Title Suggestion: Dragged Into Another World's War

It's more descriptive of the trope, methinks.

Also, I think the Transformers example should be categorized to encompass the entire franchise, since Earth being caught in the crossfire between the two main factions has been a staple of the franchise across most of its media since G1.

Mar 14th 2019 at 9:05:26 PM

^ The current title is good enough as it is.

Mar 15th 2019 at 8:48:03 PM

I've actually been thinking of making a similar draft myself. Oh well.

So in other words Faction 1 and 2 of World A have been fighting for eons. Faction 1 finds out about World B and spies on them in case they become useful. Faction 2 learns of World B's existence, so Faction 2 sends its forces to World B, and World B becomes another battleground for World A's war.

Edit: Added hat.

@JAG 001 Yeah, the current name works much better since itís shorter and is closer to another trope related trope, Trapped In Another World.

This was the initial set-up of Wild CATS, with Earth as one battleground in a war between the good-coded Kherubim and the evil-coded Daemonites. Things later got more complicated and morally greyer.
