Captured Super Entity



"Keller: And you didn't think that the United States military might need to know that you're keeping a hostile alien robot frozen in the basement? Tom Banachek: Until these events we had no credible threats to national security. Keller: Well, you got one now!"

- Transformers (2007)

This trope covers the idea of (usually) "lesser" beings capturing an alien, a god, an angel, etc, for some typically nefarious purpose. Obviously, some form of powerful magic or advanced technology will be needed to pull this off, making it a more common plot in Fantasy or Speculative Fiction.

It's also a standard "The Men in Black" plot, in which the government or secret organization has miraculously captured a powerful entity and are extracting its knowledge and power usually through various unpleasant means. If the being comes with technology, they've been "reverse-engineering" its tech for themselves. Extra MIB points if this is occurring in Area 51.

If you've heard of the technology that came from this somewhat unlikely detainment, then ET Gave Us Wi-Fi.

Naturally, should the entity's species find out about this, they're gonna be pissed, leading to the threat of The End of the World as We Know It. This may be justified, if said race was going to destroy us anyway. Oh, and Heaven help you if the captured entity is just a baby, and Mom comes calling. But even without outside help, in most cases the captured being probably won't be a prisoner for very long. So you are well advised to stand clear.

If the entity is forced to obey commands, this becomes Olympus Mons. If the entity is a Power Source, it may be Powered by a Forsaken Child. If the focus is on simple containment of the entity or its power, you wind up with Sealed Evil in a Can or Sealed Good in a Can.

Anime and Manga

 * Trigun has these in the form of
 * Neon Genesis Evangelion had the organization NERV capturing two Angels, resulting in the rest of them attacking; the only defense is Humongous Mecha created cloned from said captives. That is exactly what various sides wanted.
 * And interestingly, Lilith appears to be pretty docile but its "offspring" is a bloodthirsty Mama Bear.
 * Actually, Lilith is implied to be suffering from a case of Sealed Evil in a Can - her soul was locked into Rei's body. Of course, when Rei - bearing the embryonic Adam in her womb - merges with her in End of Evangelion, Lilith's hands simply flow around the nails pinning her to the cross. Cue Apocalypse Wow.
 * Also, Adam is not really a super entity - at least not any more. 15 years have elapsed since its death and it managed to regenerate back into a palm-sized, vaguely hominid embryo but that's a far cry from it's original form.
 * In the second Rebuild of Evangelion movie, based off of the really bad Engrish Kaji gave us, it's implied that the Third Angel suffered from this. It awakening is what forced Mari to fight it in EVA-05
 * The Emilys in Soukou no Strain.
 * In FLCL, the phoenix-like alien with the power to steal planets, Atomsk, is imprisoned inside of the town's factory by robotic aliens.
 * This plot recurs throughout the Pokémon franchise. Some villain wants to capture a Legendary Pokémon with godlike powers and the protagonists have to stop them. In the games, though, you're encouraged to capture the Legendary Pokémon (maybe after the villains tried to use their powers), and no one bats an eye. Of course, their power in the games tends to be significantly less godlike, due to Gameplay and Story Segregation preventing a Game Breaker.
 * That, and in story, you've proven yourself to be a pure heart who will not use them for evil. The Pokémon themselves are sometimes noted as "seem to trust you".
 * It's a well-known fact that godlike entities like being sent to beat the crap out of rats and caterpillars.
 * In Fullmetal Alchemist, Father uses a philosopher's stone of over 50 million souls to imprison what he claims to be a god within his body. This gives him alchemical knowledge far beyond that of any individual human, allowing him to do such things as manipulate the weather and create nuclear fusion in the palm of his hand.
 * Long, long ago in the Tenchi Muyo! universe, way before she took on a mortal body, Washu was on our plane of existance, and was somehow imprisoned by a race. They built a planet-sized containment facility to study her, and eventually siphoned off some of her power into three Gems. Eventually, after the death of one of the Bioroids carrying one of her Gems, Tsunami became aware of what was going on. No-one knows exactly what she did then, because there were no survivors.

Comic Books

 * In the new Star Trek/Legion of Super-Heroes crossover from IDW and DC Comics, Vandal Savage is The Emperor of a very powerful version of The Terran Empire. How did he do it? He captured Q!
 * IDW's Transformers comic has the Machination creating Headmaster technology from.
 * In the original G1 Marvel Comics version, Megatron once got stuck in gun mode and picked up by a small time hood, who went around using him as a BFG. When he woke up, Megatron was not pleased.
 * When the guy stood up to Megatron though Megatron was so impressed by the guy's moxy he let him live.
 * This trope was the kickstart of the plot of The Sandman after a Ritual Magic society captured Dream of the Endless and held him for years. Of course, they were trying to get his sister, Death. Keeping him kept captured caused all sorts of horrible havoc to dreams and sleeping patterns; imagine what would have happened if they had captured Death.
 * In the Preacher (Comic Book) arc "Crusaders," it emerges that The Grail has captured an angel that supplies them with vital information.
 * In Crimson, there's an arc about a bunch of humans who capture and eat angels.
 * In Ultimate Marvel, the Russian supersoldier program is based around reverse engineering a captured alien robot (the Vision).
 * In Lucifer, Sandalphon keeps the Archangel Michael Demiurgos prisoner, using him to create a race of superbeings. Our beloved protagonist isn't too happy about this.
 * It's been "revealed" that not only was the alien AI that operated the Danger Room sentient, but that Professor X knew it was sentient but chose to essentially keep it prisoner to train the X-Men. When it finally escaped (and made itself a robot body, calling itself "Danger"), it went on a rampage seeking revenge. (This was later eased off a little, to suggest that he didn't know Danger resented being used for training, but did realize she might go berserk if freed. They've since made up and Danger is an ally of the X-Men)
 * In Empowered, there is the immortal, cosmically powerful being called The Caged Demonwolf, whom Empowered prevented from destroying the Earth by imprisoning it within "cosmic bondage gear." When her superhero team wouldn't store the now talking, enraged belt, Empowered was forced to hold on to it. Now, due to a sort of Stockholm Syndrome, The Caged Demonwolf has become both an advisor and friend, despite having an overly prurient interest in their sex lives.
 * Happened in Paperinik New Adventures: while Xadhoom is a Physical Goddess, the Evronians have the ability to capture her, and did so FOUR TIMES. Every single time, Hilarity Ensued: the first time they used a forcefield that could keep her sealed that was fueled by Duckburg's electrical grid, so Xadhoom was free the very moment Uno hacked the computers; the second time Xadhoom entered in their capturing device in a deal to save Angus, and disintegrated it the very moment the Evronians broke the deal; the third time they immediately transmitted her where they had a way to force her to comply, but Paperinik's sabotage brought her back (cue Oh Crap for the Evronians); the fourth time they had her people in hostage, so she let herself being captured until her people rebelled and provoked enough chaos for her to escape and wipe out the HEART of the Evronian Empire. The Evronians tried it three other times, but it failed even more embarassingly: the first failed attempt consisted in a group of Evronians masquerading as Xerbians to get her to wear a controlling device, but she caught them on a slip and made a fool out of them before wiping them out; the second consisted in a weapon capable to absorb her enormous power, a weapon that wasn't fast enough in the absorption to finish her before she destroyed it; the third time in the middle of a battle they tried again the forcefield that captured her the first time, but Xadhoom dodged and they captured one of their own ships.
 * The Chinese and Japanese governments in Irredeemable eventually reveals they have done this two a pair of extraterrestrial, time traveling, reality altering dimension hoppers. They can release them to take care of a returned Plutonian, but simply doing so will unleash a cloud of radiation that will kill one-third of the human race. They do so.

Film

 * The live-action Transformers movie has the U.S. government in possession of a frozen Megatron and The All-Spark. All modern technology supposedly came from decades of reverse-engineering the former.
 * Even cars, which were some 20 years before they found Megatron.
 * The movie Independence Day has the government doing the same thing with a crashed alien fighter pilot. In a departure from trope, the captured alien fighter does not inspire the aliens to get angry and try to kill humanity—it's the aliens attempts to try and kill humanity that prompts the US government to take one of them prisoner. Nor does any modern technology seem to come from reverse-engineering the ship; the scientists working on it couldn't even duplicate the powersource the aliens used.
 * While not the entire god, the villains in Princess Mononoke want the Shishigami's head. It's still alive even after it gets blown off, though. This is an issue because it is also the god of death. The body remains alive. It wants its head back. Apply preschool arithmetic here.
 * Averted in the first Ghostbusters movie. With all the capturing of ghosts, when they encounter an actual god, you expect them to capture it and contain it like all the ghosts. But all they end up being able to do is close the portal that is giving it access to our universe.

Literature

 * Literary example: In the opening of one of the Nightside novels, John Taylor is called on to discover why a ghost is constantly sabotaging a power plant. He finds out that the plant operates by sucking power from a trapped and tormented solar being; the ghost is that of his enraged bride. Both were poisoned on their wedding day by the man who now runs the plant. For extra value, all three (captured being, ghost, and plant owner) were friends of John.
 * An attempt to capture such a super entity is at the climax of Andrew Greeley's novel Angel Fire.
 * The demon X(A/N)th in Piers Anthony's Xanth series is a voluntary one, and the source of the land's magical properties.
 * In an out-of-print Dean Koontz's novel Fear that Man an inventor, using Some Kind of Force Field technology, captures something. When he understands that he captured, he keeps it imprisoned, fearing retribution. Consequently, life in the entire galaxy takes a very definite turn to the better...
 * Using the magical power of Captured Super Entities is the entire premise behind Dragon and Phoenix. The Jehangli empire is powered by a captured phoenix, which is held in place by a captured truedragon, and one of the nobles plans to capture the protagonist Dragonlords in order to assume power.
 * In the excellent short story "A Colder War" by Charles Stross, the Soviet Union does this to friggin' Cthulhu. It doesn't end well.
 * Inverted in the Gordon R. Dickson short story "Danger—Human"—the captors are aliens and the "super-entity" is a human.
 * In both The Silmarillion and Appendixes of The Lord of the Rings the Numenorian King Al-Pharazon does this to none other than Sauron. Turns out a subversion, since Sauron allowed himself to be captured to corrupt and destroy his enemies from within.
 * The third book of the Mortal Instruments series has Jace and Clary finding a real angel in the Big Bad's basement.
 * Buffy the Vampire Slayer "The Lost Slayer" : Vampire king Giles keeps the bat-god-demon Camazotz captive so that he can feed on him. A turn from the onscreen rule that vamps don't like demon blood.

Live-Action TV

 * One of the many plots in The X-Files.
 * This was the essential plot of the Pilot of Star Trek: The Next Generation, "Encounter at Farpoint." Here, the Enterprise is sent to investigate a mysterious base offered by a population who obviously do not have the engineering skill to build it, and where anything you want seems to mysteriously appear. It turns out that the base is actually a giant creature enslaved by the population, and its mate arrives to retaliate. Fortunately, the Enterprise figures out the situation and frees the creature to resolve the crisis.
 * Billionaire Henry van Statten keeps a captured Dalek in his underground bunker in the Doctor Who episode "Dalek".
 * The contents of the Pandorica. The most deadly and terrifying creature in the entire universe is supposedly trapped inside it. Guess who.
 * Abaddon under the Torchwood Rift and Satan in the... Satan Pit.
 * The Timelord 'Genesis Arc'.
 * In Stargate SG-1, SG-1 found an advanced human named Khalek who demonstrated telekinetic and telepathic abilities in the episode 'Prototype'. The SGC at first attempted to study him, and for security restrained him in a chair over an electrified floor in an isolated room whose only exit was through a Tok'ra one-way forcefield, on a dopamine inhibitor to restrain his powers with it set up to dump a massive dose into his system if he were to try anything funny. It didn't work. He telekinetically pinched the dopamine tube by effectively melting it with his mind, and then he yanked the guards through the forcefield onto the electrified floor. The electrified floor was shut down from outside by Colonel Mitchell to make it safe to step in the doorway to shoot at him, but he never got any shots off - just got shoved into the wall. From that point on Khalek basically just went through the SGC to the stargate, weaponless, telekinetically deflecting all the bullets that were fired at him and shoving all the guards into walls, knocking them out (or worse). In the end, he reached the stargate, dialed home, and walked through triumphant... Only to have his home's dialing defenses dial back, resulting in him stepping back into the SGC, befuddled. Seconds later, he was being shot at from two different angles, and failed to block one of the two sets of bullets, resulting in his demise.
 * There was also the water in the fourth-season episode Watergate.
 * Stargate members attempt (they usually just stick at this, and not permanently contain) multiple super powerful creatures and entities. More notable among others, and   as a Prior.
 * While memory is vague, Seven Days has an alien with knowledge of the Sphere kept on ice or something. It doesn't end well...
 * Only because "Adam" is a prisoner, who was being transported somewhere when the ship crashed in Roswell.
 * Xena: Warrior Princess episode "Death in Chains": King Sisyphus takes Celesta (Hades' sister and the goddess of death) prisoner so she can't take him to the Underworld.
 * This was the purpose of the Initiative in Buffy the Vampire Slayer.

Oral Tradition, Folklore, Myths and Legends

 * This happens with the genies of Arabic mythology. Djinn were essentially free ethereal spirits with magical talents summoned and bounded to an object, such as a bottle or oil lamp, and had to serve (if they are in a good mood) whoever is currently in possession of the object or summons them via object.
 * The part you're supposed to be impressed about, however, lies less in the fact that the hero (for certain loose definitions of hero) comes into the possession of such an object, but rather that there was a human sorcerer powerful enough to force and bind one of these proto-Angels into servitude.
 * Actually based on an ancient grimiore The Keys of Solomon! He used his knowledge of Kabbalah to bind 72 demons in a chalice! It eventually morphed into this. Damien-Daemon-Djinn Also, they did not mean evil spirit until centuries later!
 * In a Brothers Grimm tale, a man somehow ended up tricking Death up a tree, causing the world to descend into chaos because this kept people from dying.
 * Older Than Feudalism: Death first took an involuntary holiday in Greek Mythology, when Sisyphos captured Hades (or Thanatos, Anthropomorphic Personification of Death, in some versions) by chaining him to a tree. Nobody in the whole world could die, no matter how horribly mangled, which finally pissed off Ares, god of War, enough that he came and rescued Death. Guess who got to die first?

Tabletop Games

 * Considering that they're part of the Warhammer 40,000 universe, it shouldn't be too difficult to believe that the Eisenhorn novels feature this; when a number of captured Alpha-level Chaos Psykers are paraded through a large hive on a victory march, they manage to escape and wreak considerable havoc, including . Several of Eisenhorn's opponents  also make use of daemonhosts: immensely powerful daemons bound into human bodies, which are both immensely dangerous and intensely displeased with their enforced servitude.
 * Alpha Level Plus Pshykers are far more dangerous than you might think. ONE AL+ Pshyker managed to enslave over fifty thousand innocents, and force them into combat against his enemies, he could even influence and control Space Marines to a lesser degree, allowing him so slip away unharmed when fifteen marin es were right next to him... one even picked him up thinking him an ordinary six year old...
 * In the Kamigawa block of Magic: The Gathering, a feudal lord captures a newborn spirit from the Spirit World, which makes him immortal. This act also incites the entire spirit world to declare a long and bloody war on the mortal world.
 * The worst part is, the long and bloody war with the gods of his world doesn't cause him to take the hint; he's still convinced that his immortal reign is the best for Kamigawa. Which trope is that again?
 * The Men in Black in Deadlands actually don't traffic much in Captured Super Entities. Hellstromme Industries, on the other hand, uses one to power  For more information, refer to the example listed in Sadistic Choice. You were warned.
 * The central idea behind Pokethulhu. Like in Pokémon, you capture and train monsters. Unlike Pokémon, they're all soul-eating Eldritch Abominations with horrifying and/or reality-bending powers.

Video Games

 * Final Fantasy VI has The Empire doing this to a race of beings called Espers. They actually succeed in slaughtering most of their entire race.
 * But only after said race of beings cripple the Empire.
 * Final Fantasy VII also has JENOVA being exploited by the Shinra Corporation for super-soldier experiments (although technically she was captured by the Cetra centuries before).
 * In World of Warcraft, the Blood Elves are holding a Naaru captive within Silvermoon City; this is how they have harnessed the power of the Holy Light and made their own Paladins. (They also had Paladins in Warcraft 3, but that's different.) This source of power is abandoned in Patch 2.4.
 * Intriguingly, the Naaru never seemed to care much, leading to theories that it was all a Xanatos Gambit to "corrupt" the Blood Elves with Holy Light.
 * Another example is draining the blood of the demon Magtheridon to create fel orcs, and the two backfiring attempts to use the human avatar of the Sunwell in this way. Demon Hunters have a miniature version of this happening, in that they seal a demon inside themselves to empower them. The warlocks in the Shadow Labyrinth seem to be trying this trope, though they also seem to be pretty bad at actually controlling their major summons.
 * In City of Villains,
 * Anyone who finds it suspicious that the giant cables and pipes throughout Cap au Diable are covered in demons made of red lightning need not worry about the above spoiler.
 * In Xenogears, the entity known as the Wave Existence is trapped within the Zohar Modifier and used as a power source for the Deus Superweapon.
 * Happens in Persona 3 with the Shadows.
 * Jade Empire has The Water Dragon, the goddess of reincarnation and water, severely wounded by the Emperor, and her body turned into a trophy so that he can maintain his phenomenal cosmic power.
 * In Neverwinter Nights Hordes of the Underdark, the bad guys have somehow caged an angel and are using her to create an army of bone golems. If you free her, she'll help you out at the end of chapter 2.
 * There is also a caged arch devil, who manages to escape after you kill it's 'jailer', a drow matron.
 * Tales of Phantasia has the high-tech ancient city of Thor, powered by Asuka, an imprisoned light spirit.
 * In Pokémon Diamond and Pearl, you can fight Arceus...and capture him to do your bidding. Also a case of Did You Just Punch Out Cthulhu?.
 * XD001 in Pokémon XD, AKA Shadow Lugia. He is also a Anticlimax Boss if you remember the major advantage you got shortly (storyline-wise) before the fight: The Master Ball.
 * Cyrus also pulls this on Dialga and Palkia (who are essentially deities of time and space). While you can capture them with Poke Balls, Cyrus just flat out attempts to destroy the universe and recreate it so there are no troubling emotions.
 * Resistance 2 starts with the heroes knowingly releasing the super entity Daedalus, the being apparently in control of the Chimera, and being unable to stop it from escaping.
 * Lost Kingdoms had . It went crazy in the first game but by the second, it's a humble servant to the throne (and it unlocks the castle too).

Web Comics

 * In Sluggy Freelance Hereti-Corp has done this with both Aylee and Oasis.

Web Original

 * In The Gamers Alliance, Awar manages to trap the god Shakkan into a shard of Krystallopyr during the Vanna arc, prompting the heroes to find a way to set the god free before the god's lizardfolk followers obliterate all humans in the desert in revenge.
 * The SCP Foundation has several of these, up to a man who claims to be God. Although their method of "capturing" him essentially consists of them knowing that he'll be back and not worrying too much that he can get out of his cell whenever it takes his fancy.

Western Animation
"Elder Frink: Why, that would require some sort of "re-bigulator", which is just such a preposterous -- [ Death Glare from Lisa]"
 * In Transformers Animated, Megatron's head is found by Isaac Sumdac and becomes the base of all future technology, but he has no idea who he is. Then he wakes up and Megatron is able to trick him into not revealing his presence to the Autobots and helping him rebuild his body.
 * In the Aeon Flux episode The Demiurge, a war is fought over whether to keep a powerful, ostensibly-benevolent godlike being around for the good of all, or to blast it off into friggin' outer space on a rocket for the good of all.
 * In one "Treehouse Of Horror" episode of The Simpsons, Lisa inadvertently creates a miniature society around a loose tooth. Said society (which views her as God and Bart as Satan), eventually "Debigulates" her down to their level. Problem is, they can't return her to normal.
