Speculative fiction, especially Dystopian and Cyberpunk fiction, tends to lean toward massive corporations. These corporations are usually umbrella corporations, controlling dozens of smaller companies that manufacture everything from clothing to military hardware. They can even be the police. Perhaps there is even one company that is a Privately Owned Society in its own right. This goes beyond the definition of "monopoly."
Rarely are Mega Corporations portrayed with anything other than unremitting negativism; rather than being a simple business making things that people want to buy, they are almost invariably the villains of the setting, and depicted as exploitative, oppressive and screwing the rules with their money while maintaining a Peace & Love Incorporated façade. They are home to the Corrupt Corporate Executive, Mean Boss, Pointy-Haired Boss, and Obstructive Bureaucrat, and usually have Amoral Attorneys on the payroll.
Mega Corporations are shown to be private institutions and therefore don't have to play by most rules the government has to, such as freedom of speech, because it's always "nobody is forcing you to work for them or buy from them or use their institutions or buy their products." However, more dark versions will also show these guys pretty much buying off or eliminating their competitors, brainwashing the masses, and coming up with Evil Plans to ensure they have a monopoly and making it so that you still have to buy their products, while their employees are sometimes portrayed as oppressed, paid pitifully low wages (if at all), and treated as expendable.
They may also be shown controlling the government either through having employees in important positions or through lobbying, or taken to its extreme, may have Private Military Contractors or other Hired Guns (or even an entire country or world) at their disposal, and become Superpowers in their own right. Corporate Warfare may result if financial means are not enough to accomplish the company's goals. In shows seeking a Green Aesop a Mega Corp could also be Toxic, Inc..
A more benign version may be owned by a Rich Idiot with No Day Job. However, in Post Cyber Punk stories, some Mega Corps can aspire to be Big Good, providing the hero with amazing equipment in their quest to literally snuff out the competition. There do exist some rare benevolent portrayals of a Mega Corp; in which they merely may just be a large business who employs a lot of people but isn't shown practicing in unethical trade practices.
Monopolies, monopsonies (only one buyer of goods in the market), duopolies (only two sellers in the market), and oligopolies (only a small handful of Mega Corp entities that are selling in the market) do exist in real life, and indeed, very large multinational corporations do exist. And yes, some of these corporations do engage in unethical practices or political influence. And there areReal Life historical examples of Mega Corps acting either as a state within state or as an semi-independent political entity, such as the Hanseatic League. Of course, it is an exaggeration (at least) to claim allcorporations act in this way.
Capsule Corp. from Dragon Ball produces everything from houses to cars, and then puts them in a small portable (as in, pocket-sized) capsule. The Brief family is so rich that they build people space crafts for free. One of the few examples of a Mega Corp that's an unambiguously positive force in society. Eventually their product line is expanded to spaceships and (in alternate universes) a time machine, but those aren't for sale and instead are just used by the Brief family and their personal friends (who happen to be the heroes of the story).
The Paradigm Corporation in The Big O controls everything inside Paradigm City.
Nergal from Martian Successor Nadesico is a somewhat more benign example, but it's a private company with enough resources to build and crew its own spaceship. Everything on board is a Nergal product.
Paradias in Yu-Gi-Oh!, which possessed shares in every company on the planet and held sway over world governments in addition to being a front for the Cult and its Ancient Conspiracy.
One rather interesting thing about the dub of Yu-Gi-Oh!. In the Japanese version, Alistair's grudge against Kaiba Corps was that they supplied the tanks that killed his brother. In the Dub? Kaiba Corps bought the land he (among many others including his family) were living on and were forcing them out with tanks. Sound like something you'd expect out of a Cyberpunk story.
Then it's revealed Paradias was the actual culprit and they mislead Alistair into thinking it was Kaiba Corp because Paradias' head wanted Alistair to hate Kaiba.
Yiliaster from Yu-Gi-Oh! 5Ds is even closer to this, considering they have so much technology and money that they can actually manipulate the time stream.
Genom Corporation from Bubblegum Crisis is a sprawling global economic powerhouse which manufactures everything from toasters to military cyborgs (Boomers). It exerts tremendous influence on the world's governments and entertains plans for overt world domination through the use of the so-called Overmind Control System, which is presumably capable of remotely controlling all AIs on the planet.
Daiwa Heavy Industries from Vexille succeed in assuming complete control of Japan, eradicating most of its population and turning the survivors into cyborg drones. They also have plans to do the same on a worldwide scale.
Death Note: The Yotsuba Corporation. According to How to Read 13, it is a massive international corporate conglomerate that employs over 300,000 people and is involved in everything from heavy industry to resort development to military weapons. It gets even more powerful when the Yotsuba Group uses the Death Note to kill off Yotsuba's rivals. Their security is very lax though and after Light kills the Yotsuba Group, the Megacorporation's stock plummets and the Yotsuba Corporation loses much of its influence.
Anaheim Electronics from the Universal Century Gundams, which grew to power after acquiring the assets of the Zeonic Corporation after the One Year War. They had a bad habit of selling out to both sides in a conflict, which may have been part of the reason they lost their contract with the Earth Federation to SNRI, although this wasn't always the case. The stuff that happened in Operation Stardust wasn't actually their fault. And the profiteering mindset came about after the Gryps Conflict as they actually threw in their lot with AEUG but were contractually bound to supply the Titans despite all the restrictions that were forced onto them.
It also helped that the Moon, their main base of operation, was kind of a SpaceSwitzerland, and consistently remained neutral in the most conflicts around the Earth Sphere. Though real-life Switzerland rarely sells weapons larger than a handgun to foreign militaries. By the events of Mobile Suit Crossbone Gundam, set 10-13 years after F91, it's mentioned that Anaheim has weakened to the point of desperation. Which SNRI and the Crossbone Vanguard take advantage of. Anaheim does return back to prominence by the time of Victory Gundam. Especially when it's revealed that they're the true benefactors behind the League Militaire, reminiscent of the vital support they provided to the AEUG back in Zeta Gundam. In Mobile Suit Gundam Unicorn however, it's also revealed that Anaheim is just the main front corporation for the much more secretive and elusive Vist Foundation.
Myth Corp in Mythic Quest.
Darkside Blues had the company Persona Century, which had bought over 90% of Earth's surace.
Holy Nightmare Corporation/Nightmare Enterprises in Kirby of the Stars, the owner of the company being a Galactic Conqueror known in the original version as the "Emperor of Darkness".
The Deep Galaxy Trade Organization is a huge corporate oligarchy who stamps out all forms of entertainment to maintain it's galactic empire in AKB0048.
There's several to be had in Ghost in the Shell, both the films and the series: a significant majority of cases that Section 9 involves itself it has to deal with massive levels of corporate corruption in the government, and often it seems like Section 9 is the only organization bothering to keep such issues in check.
In Magical Record Lyrical Nanoha Force, a recent developing one is the Vandein Corporation. It's unknown of what else they sell, but they have recently been the manufacturers behind mass-produced Anti-Magic weapons based on incredibly powerful Lost Technology. Since their arrival, the manga has been having some Evil Versus Evil as both the TSAB and the Hucks see them as a problem.
Though Cinq Flèches of Blood+ is described as a pharmaceutical corporation, it has such as technology, food production, military contracting, and, of course, Chiropteran-based genetic manipulation. They even own and run an all-girls high school in Vietnam.
The Enterprise from the manga version of Strider, who are said to deal with food distribution as well as warfare and weapon research, have their own special forces unit as security personnel and a secret Mind-Control Device project to rule over the world. It also figures in the NES game that adapts the manga, though much less prominently.
LexCorp from The DCU, which employs roughly a third of the people in Metropolis, runs everything from the supermarket to the daily news, and exists primarily as a tool in its CEO's plan to destroy one single individual. At one point its CEO was Lana Lang, who had to explain to Superman that the structure of the company is such she can't stop it making Kryptonite weapons without laying off a lot of people. She was removed from the position when it turned out all Lexcorp contracts had a standard clause automatically firing people who used Lexcorp resources to help the Kryptonian. Ironically, the CEO who did the most good with LexCorp was Talia Al Ghul, an Anti-Heroine / Anti-Villain at best and the loyal daughter of an immortal eco-terrorist bent on eradicating humanity. Her solution? Sell everything, and leave Lex with nothing (she did it for her boyfriend). Didn't last very long, though.
Batman: Wayne Enterprises is a rare example of a Mega Corp out to do good. Bruce Wayne took over his late father's corrupted company and turned it into a force against poverty, unemployment, and other societal ills he couldn't handle with a Batarang. Like Luthor's company, it controls most business in Gotham City. This probably explains why Gotham is still a bustling growth city considering the fact that people like Joker run amok on a nightly basis. It is usually second only to LexCorp in international clout, as well; similarly, Wayne is usually described as the second-wealthiest man in the world.
This becomes particularly relevant in Batman Begins, as Wayne Tower is the central hub of everything in Gotham, and that becomes critical to the Big Bad's plan.
As the No Man's Land arc finishes Bruce Wayne ends up becoming more important than Batman as its only his downright massive spending on rebuilding Gotham that keeps Luthor from taking control of it like Metropolis. Well, that and the recovery of records that prove land ownership that prevented Luthor from taking land for himself.
There are also smaller mega-corporations owned by other heroes, like Queen Industries and Kord Technology.
Clay Industries in PS238, which seems to sell all the materials needed to build the elaborate superhero bases, security systems and other useful pieces of equipment used by the school, many of the superheroes and Praetorian Academy. They're also implied to sell "instant-buildings", explaining how a universe so rich in superheroes manages to survive all the inevitable property damage. It seems to be a fairly benign company, as the founder and owner appears to be the school's janitor.
The Zinco company, which serves as the Hellboy universe's rough Lexcorp equivalent. Was run by a pair of Nazi occultist supervillain fanboys until they both got themselves killed in separate attempts to defeat the BPRD and kick-start The End of the World as We Know It.
American Flagg has The Plex, which runs the former United States and Soviet Union from its new "temporary" headquarters on Mars. Another Mega Corp, Four World Industries, appears to essentially control the government of one of Earth's two superpowers, the Brazilian Union of the Americas.
Scrooge McDuck started out as prospector and used that capital to buy a small bank, and from that he put together a Mega Corp. so massive he sometimes forgets parts of it, producing items in pretty much every possible business save for weapons (at least we never saw those) and owning almost all of Duckburg (at some point the only things he didn't own in Duckburg was Grandma Duck's farm, but sold some lands and allowed smaller companies to be born). It's also a very benign one, as Scrooge is a fair and honest person (even if really greedy and tigh-fisted) and respects the environment, and any executive trying to use one of the smaller companies for crimes or ruining the environment is liable to be personally exposed by Scrooge, fired and turned to the authorities.
Mr. Evil'sHeroHighSeries has Sphinx Corp. Hinted at the end of the first, played strait with practically owning the town in book two, and in book 3 it grows so powerful they purchase a city and becomes recognized as a major government power by the end.
Kitsune no Ken: Fist of the Fox: Konoha Town has two of these, the Uchiha Zaibatsu and the Hyuga Corporation (or Hyuga Corp for short), as explained to Naruto by Shino soon after the former's arrival in the town. According to Shino, the Uchiha Zaibatsu owns most of the businesses in Konoha Town, including supermarkets, hardware stores, boutiques, and at least one bank; on the other hand, Hyuga Corp specializes in shipping imports and exports, electronic technology, and local transportation maintenance (meaning they have control over the local bus and taxi service); and both companies are rivals to each other, and are in a race to see who can land the country's biggest military contract first. Shino adds that his father is a telecommunications engineer for a mobile-phone company whose parent company is Hyuga Corp, and that any of Ino's family's greengrocery customers could be earning money from either of the two groups.
Films — Animation
Buy N Large, from WALL•E, a barely-disguised scathing satire of Wal-Mart. It's so large that the CEO is President of the World - we even see the White House press room redone with the Buy N Large logo.
Octan, from The Lego Movie. Like the WALL-E example above, the president of Octan is also the president of the world, and the Big Bad.
Cyberdyne from the Terminator films. While not exactly evil like Cameron's other Mega Corps, they're certainly unscrupulous to the point that they can convince the military to have all its defenses run by Skynet. Their high-tech invention ends up causing The End of the World as We Know It and the subsequent Robot War.
Weyland-Yutani, Alien franchise. Famously evil enough to sacrifice squads of colonial marines, entire colonies, and the security of the Earth in its attempt to weaponize the eponymous alien critters... and in the fourth film eventually bought out by an even more evil rival, Wal-Mart. In this case though Cameron did not make the mega corp; it was already present and evil in the original Alien; Cameron just fleshed it out.
Avatar brings us the Resources Development Administration, an interstellar mining and transportation firm which swings more meat than most countries.
Omni Consumer Products from Robocop is another iconic example: they have divisions in such diverse fields as consumer products, healthcare, prisons, space exploration, law enforcement to military grade weaponry and their ultimate goal is to turn Detroit into Delta City, One City Under Copyright. They're bought out by Kanemitsu in the third film.
Inspector Gadget has Scolex Industries, which produces technology such as robots and androids (such as the RoboGadget line).
The Trade Federation in the prequel trilogy is wealthy and influential enough to maintain its own navy (albeit one composed of converted cargo ships) and blockade entire planets at a whim, as well as have its own seat in the Galactic Senate. Yeah, they were rich enough to explicitly buy political power. (And they were only the largest one. The whole Separatist Army during the Clone Wars was led by factions like this, such as the Banking Clan, the Techno Union, Geonosian Industries, and the Commerce Guild. The entire reason the conflict started seemed to be a dispute over new trade tariffs, which Palpatine was quick to take advantage of.)
The presence of fellow Mega Corps the Techno Union and Banking Clan in the Separatist army suggests that maintaining a giant army of killer Deathbots is a standard business practice in the Star Wars galaxy. It was until (explained in the Expanded Universe) the Galactic Empire outlawed military droids. Though this didn't stop many criminal and quasi-legal organizations from employing large forces of "security guard droids".
Also from the Expanded Universe, Kuat Drive Yards is the Empire's primary manufacturer of starships. This company is powerful enough to have a security fleet comprised mostly of Star Battlecruisers and Star Dreadnoughts that dwarf the Empire's iconic Star Destroyers, each of which is in turn, powerful enough to scare a star system into submission. Talk about overkill. Granted, Kuat is under exclusive contract with the Empire, and is thus allowed to maintain said security force. In addition, the Empire has even more of said Star Dreadnoughts, the most famous of which is the Executor, Vader's Super Star Destroyer. And also includes the Emperor's personal Super Star Destroyer, the Eclipse...which has as its main armament a miniaturized Death Star Superlaser. Which luckily was still under construction at the time of the movies.
As with KDY, the Corellian Engineering Corpooration (CEC) enjoys its own huge security fleet, though it is not involved purely in military contracts (which one could argue simply makes CEC all the more alarming). Its success has made it arguably the most prolific of the huge manufacturing supercorporations in the Expanded Universe. Oh, and they happen to jointly own a military subcontractor with Kuat, and purchased one of their Corellian rivals when a travel accident killed off the executive staff.
Other major players in the galactic war include Incom Corporation (makes X-Wings), Sienar Fleet Systems (makers of the entire TIE line, as well as Darth Maul's ship), and Blas Tech (makes all those blasters).
Czerka Corp. in Knights of the Old Republic doesn't have its own navy, but it does own and enslave entire planets (Kashyyyk being one of them) and is utterly indifferent to the outcome of the Jedi Civil War. They're also outside the law. One of the loading screens in the game says that Companies like Czerka police themselves because they're too big for authorities to handle.
The Corporate Sector Authority, first seen in the early Han Solo Adventure novels, owns a sector of space (the Corporate Sector), in which the Empire permits it to harvest and exploit resources with impunity. Strip-mine entire worlds? Enslave whole populations? Execute workers for conspiring to form labor unions? Check, Check, and Check. As long as they pay their tribute to the Emperor (which is much lower than what their taxes would be if they operated in the Empire proper), anything goes.
In Videodrome, the Spectacular Optical corporation is revealed to have stolen Videodrome (a mysterious force that can give people the power to warp reality) from its creator, Dr. Brian O'Blivion, and assassinated him with it. While O'Blivion wanted to use Videodrome to help the human race, Spectacular Optical uses it to further their own evil goals of world domination. According to its CEO Barry Covex, the company makes everything from cheap glasses to missiles.
In his version of The Fly, Bartok Science Industries is the company that funds brilliant inventor Seth Brundle's work in teleportation technology.
In The Fly II, Bartok Industries is much more evil, forcing Seth's son, Martin, to unlock the code that his father used on the telepods. The company's CEO, Anton Bartok, first tested the telepods with a golden retriever, which survived the experiment but become horribly deformed, and later lied to him that the dog was euthanized, but was actually kept alive for observation. The company records him having sex with his girlfriend, and then attempts to use his unique biology and relationship to the telepods for power and control.
The Big Bad in Repo! The Genetic Opera, GeneCo, definitely counts, what with the selling you organs which will be repossessed if you don't make payments for 90 days (which is common in the future), getting you hooked on drugs, and generally being jerks. But they did save the world at one point.
District 9's MNU is a private security firm tasked with managing the millions of aliens on earth, but in reality are only interested in the aliens' weapons. They force the aliens to live in slum-like conditions, treat them like crap and spread lies about them to keep the them in a bad light. Even MNU's own employees are in the dark about most of their activities, for example that they have been experimenting on aliens, vivisecting them and trying to create human-alien hybrids.
The International is about efforts to investigate an international bank that finances third world revolution, money laundering and arms trading. Based on the real life BCCI.
The Zorg Corporation from The Fifth Element has business interests ranging from taxi service to weapons manufacturing, plus a CEO who sells out humanity to the Big Bad in exchange for a couple extra bucks and personally attempts to kill the heroes when his hired guns can't do it.
The Very Big Corporation of America in The Crimson Permanent Assurance short that leads into Monty Python's The Meaning of Life. The board room is covered with the names of the smaller businesses they gobbled up.
In Mel Brooks's Silent Movie, Mel's little movie production company is in danger of getting stomped into a little greasy spot on the pavement by the ultra-gigantic Mega Corp studio Engulf & Devour.
In the TRON franchise, the corporation known as ENCOM tends to display Mega Corp tendencies whenever it's not being controlled by idealists like founder Dr. Walter Gibbs or Kevin Flynn.
Xyrex in Parasite, which comissioned the creation of the title creatures.
Speed Racer features the conglomerate "Royalton Industries" name after its owner E.P. Arnold Royalton.
James Bond has some of these usually involved in criminal conspiracies.
Armadyne in Elysium, who makes everything from security robots to the all-cure machines known as the Med-Pod 300s.
In Cube 2: Hypercube there's the Izon organization, which is implied in this film to be behind the cube. It has multiple secret subsidiaries and connections with the U.S. military and Washington think tanks, while having enough power for black ops experiments in building extra-dimensional mazes.
Manpower Incorporated is the poster boy of this trope. They own and control entire planets, have their own space navy, their own army complete with combat line clones, own other corporations, their main products are genetic slave clones, and practically dictate the foreign and domestic policy of not one, not two, but dozens of star nations. To add icing on the cake, their CEO Albrecht Dettweiler, is a genetically engineeredMagnificent Bastard; with major emphasis on the bastard part. And the whole affair is a giant, ultimately disposable front. For the actual government that is supposedly its thinly veiled puppet. Talk about a Double Blind.
Although Manpower is widespread and powerful, they are not alone in being a system spanning Mega corp. Kinder examples such as the Hauptman Cartel and Honor's own company. Plus the Mafia planets like Erewhon.
The novel Oryx and Crake by Margaret Atwood features many of these, most of which are bio-corporations or health 'care' industries. The employees of these corporations live in secure compounds, seperated from the ordinary city, which they believe is dangerous and disease-riddled. These Megacorporations also have their own security corps, the Corpsecorps, which has replaced ordinary law enforcement and is a commercial and very corrupt company.
Combine Honnete Ober Advancer Mercantiles (CHOAM (roughly translated as "The Corporation of Honest Profit Traders")). They control all interstellar business in the Imperium except for star travel. The major stockholders of CHOAM consist of the Emperor, the Bene Gesserit sisterhood and... the Spacing Guild. CHOAM has the curious distinction of being a mega corp in a feudal society. The main indication of political power among the nobility is the possession of CHOAM stock and directorships.
The Guild could actually be considered a mega-corporation in its own right(beyond the fact they have a sizeable stock, the exact figure never given, but probably a third, in CHOAM) — CHOAM controls trade, but guild ships are required to move anything out of a particular system, and they have an absolute monopoly on spaceships, and are the only organisation who can travel in space, and as such are tremendously rich and powerful.
Jennifer Government has two giant corporate alliances, US Alliance and Team Advantage, that cover the strongest and second strongest corporations of every trade, respectively. Any independent companies have long since gone bankrupt.
The Thursday Next books have the Goliath Corporation, which produces everything "from cradles to coffins." They're also more or less the main villains of the series. Well, at least the executives of Goliath are. The Mooks lean more towards Punch Clock Villainy.
The concept is a heavily examined theme in Kim Stanley Robinson's Red Mars Trilogy, where modern multinational corporations successively evolve into "transnational corporations" (transnats) and then "metanational corporations" (metanats, richer and powerful than most nations on earth) over the first two books before they effectively collapse in the face of a global catastrophe and worldwide uprisings near the end of the second book.
Podkayne of Mars . The Venus Corporation, which controls the entire planet.
In Friday, the Shipstone corporation owns, by the protagonist's own accounting, everything on Earth — to the point where it controls nuclear weapons and uses them on countries that piss it off; and its internal "power struggles" are resolved by mass assassination. It is made clear that Territorial States don't stand a real chance against Corporate States.
The main plot of Magic, Inc.. is about the eponymous corporation taking over all magical dealings first in the city, then the state and the US. The heroes find out that it is a literal evil corporation when they discover that the founder and CEO is a high ranking demon from hell.
Used and subverted with Event Horizon from the Mindstar sci-fi detective series by Peter F. Hamilton. Although mega corporations are more powerful than governments, the young and patriotic CEO Julia Evans keeps most of her industry in Britain to provide work and a strong economy, rather than subcontracting out to cheaper Pacific Rim countries. This also increases Event Horizon's power and influence within Britain.
In his stand-alone novel Fallen Dragon, Earth is essentially run by the megacorporations, and they have far more power than national governments. Zantiu-Braun is the largest, with one character commenting off-hand that Z-B own "half the bloody planet these days". Z-B is also the only corporation large enough - and willing enough - to still be able to fund exploratory missions, although new colonies are now founded through one-shot wormholes and left to fend for themselves rather than via starship. The remaining starships are repurposed by the corporations into the only interstellar venture that remains profitable: "asset realisation", or the pillaging of colony planets in debt to the aforementioned corporations for material to sell. The corporations buy out struggling debt-laden founding companies in order to provide some kind of legal basis for their asset realisation missions, and then send invasion fleets to subjugate and pillage the colony planets for valuable industrial assets to sell at a profit, thanks to the production costs being cut out. Essentially, it's piracy. Muddying the waters a little bit, Z-B's ultimate motive is to elevate the human race via corporate stakeholding, which essentially means corporate socialism, in order for humanity to truly reach for the stars. The Board - which consists entirely of different batches of the Roderick clones - is divided on the best approach to do this, and the discovery of the dragons and their patternform technology is likely to cause an unprecedented split.
Cowles Industries, from the Dream Park series by Larry Niven and Steven Barnes, subverts the connotations of this. Huge? Check. Multidisciplinary? Check. Consider themselves above the law? Check. Manipulate people with subliminal messages? Check and Double-check. Good guys? Also check.
In the Alternate History classic For Want of a Nail by Robert Sobel, the company Kramer Associates directly runs the Philippines and Taiwan along with influencing many of the great powers economically with holdings in the United States of Mexico, Japan, The Confederation of North America, etc., and it was also the first to develop the Atomic Bomb in the 1960s. The notable thing about For Want of a Nail is that it was written well before cyberpunk popularized the sovereign corporation trope.
The Sol Corporation (otherwise known as the Earth Company) from the Alliance/Union series. They developed a monopoly on space travel, and on all resources produced by interstellar colonies, and the colonies were dependent on them to supply food and other organic materials. It wasn't until the discovery of Pell and Cyteen that it was even possible for any of the colonies to try and become independent, after which they did try. The Company's response was to manufacture a giant fleet of space battleships and go to war with the Union.
J Corp in Tad Williams' Otherland is one of these. While not as large as some of the other examples (it has competitors), it's still big enough to own a private army, cofinance a project to build the world's most powerful computer network, and tell governments to piss off. Helps that in this version of the future corporations hold seats in the American government, with the number of seats being determined by shares of the market.
The Syndicate Worlds from The Lost Fleet are an interstellar nation seemingly comprised of several Mega corps. Officers in the fleet are even referred to as CEOs.
Trails of Hoffman Inc. appeared in Lies Inc. The company offered teleport services to a far-off world. It was a one-way ticket, no way home. But the company definitely had its fingers in other pursuits, and whatever they were doing on Whale Mouth was not what they claimed.
New Path in A Scanner Darkly also qualifies. Though it advertises as a rehab clinic for Substance D addicts, it actually grows the plants the drug is distilled from and is implied to have connections to law enforcement and other industries.
Ubik has several, which may control reality itself.
In The Three Stigmata Of Palmer Eldritch, P. P. Layouts, Inc. has near-total control over the entertainment available to the Martian colonists, until Eldritch comes along to challenge them.
the Takeshi Kovacs series subverts this trope, in that, while the setting is dominated by Mega corps, all of the human-inhabited universe ultimately answers to the despotic United Nations Protectorate, and is utterly terrified of it, to the extent that a planetary oligarchy is unwilling to ask for Protectorate aid in the suppression of a potentially world-consuming insurrection, for fear that the Protectorate may choose to take too close an interest in the planet.
The Chartered Zarathustra Company starts out owning the entire planet of Zarathustra in H. Beam Piper's Little Fuzzy novels. Although in the end The Federation turns out to be bigger than they are. This is actually the standard Federation method of developing planets, as in "Uller Uprising". Kwannon, in "Oomphel in the Sky", is an exception.
William Gibson is considered as the father of cyberpunk, it's only fitting that his novel contains mega-corporations. His novels gave us Tessier-Ashpool S.A., Maas Biolabs and Hosaka Corporation, among others. Real-life corporation such as Hitachi and Sony also make an appearance.
General Products from Larry Niven's Known Space series is the most famous company in the known universe. It's also run by a race of genius cowards who consider blackmail moral behavior.
The Bulero corporation in George Zebrowski's Macrolife.
Benevolent example: World Enterprises in The Man Who Fell to Earth starts with and specializes in electronics but quickly grows into this because its products are so innovative; it is actually able to launch a space program. The secret? The mysterious man at the top is actually an alien who brought his dying world's technology to Earth specifically to make enough money and obtain the resources needed to save the rest of his people, who will blend in with humanity as he has and positively influence it.
INITEC (Interstellar Nanoatomic Independent Terran Empire Corporation) in the Doctor Who New Adventures novel Original Sin. Its specialty is robotics, but it also produces weaponry (including the glitterguns that saw off the Cybermen) and spaceships. Oh, and it's run by a robot with the mind ofTobias Vaughn. Small surprise, considering the real significance of the corporation's name. Interstellar Nanoatomic is a Significant Anagram for International Electromatics.
Crysis: Legion claims that Hargreave-Rasch is so big and powerful that even real-world giants like Monsanto and Halliburton are small fry compared to it. Uniquely enough (especially for a Peter Watts novel) is the fact that the entire corporation and its subsidiaries are secretly dedicated to one man's shadowed, century-long struggle to prepare humanity against an imminent conflict with Sufficiently Advanced Aliens that he first came across at Tunguska. The corp is stated to own, among other assets, an Arecibo-sized radio telescope which it uses to scan the sky for something.
In Andrey Livadny's The History of the Galaxy, the Galactic Cybersystems Corpotation used to be the primary provider of all cybernetics (from household robots to infantry droids and Humongous Mecha) for most of the known worlds. However, they reached their limit, and the heads of the corporation were afraid of a crackdown if they attempt to step beyond the legal and ethical norms imposed by The Federation. They decide to lay low for awhile, letting their competition make these steps and then come back when the laws and ethical norms have changed. It didn't quite work out this way, and Galactic Cybersystems disappeared virtually overnight due to over-consolidation (all R&D and production was done on a single planet known only to a few). The corporation was powerful enough to have its own Humongous Mecha and a private fleet. Later novels have many smaller corporations that qualify as Mega Corps by owning several worlds each, many of them striving to free themselves from the "oppressive" laws of The Federation (Does This Remind You of Anything?). One of these, under threat from a (deserved) crackdown, decides to strike out against The Federation and hold it hostage.
In The Golden Witchbreed, it seems that Earth is run gigantic Companies of the likes of NuAsia and ChinaCo. The second book has the planet Orthe being all but conquered by the PanOceania Company, which can not only monopolize on travel to an entire planet, but also has its own military and spacefleet. They're not really evil, though, (at least nowhere near as evil as the realvillain) they just want some to get their hands on the nifty technology left behind by the Precursors, and don't care what happens to the natives.
In The Unidentified by Rae Mariz, these corporations run schools. After the government ran out of money for schools, corporations bought old malls and turned them into schools, calling them "the Game". The schools are places for the teens to be marketed to and for them to test products.
In the Cybione series by Ayerdhal, the protagonist is employed by Ender, an insurance company that, amongst other things, guarantees the constitution of “a thousand worlds”.
In The Dark Tower series, North Central Positronics seems to be all over Mid-World.
Francis Carsac's novel La vermine du lion (The Vermin of the Lion) has the Interplanetary Metallurgical Bureau. Despite sounding like a state institution, it's definitely a Mega Corp. of the mining variety. Several major plot arcs are the result of the IMB attempting to strip-mine this planet or that, damn the natives.
Mind, Body & Soll LLC from The Seems was responsible for designing the Departments, as well as some of the greatest architectural wonders of The World, including Easter Island and Machu Picchu, apparently.
A recurring joke would name some fictional company (either featured in the movie or derived from someone's name) as "a subsidiary of ConHugeCo."
In the series' finale Gypsy appears to have founded a Mega Corp of her own, "ConGypsCo"
Also from MST 3 K: Novacorp, from the episode Overdrawn at the Memory Bank.
And Gencorp from Time Chasers.
Max Headroom placed the television networks, and Zik Zak, into this role.
Massive Dynamic on the show Fringe. When your name is "Massive Dynamic" and the slogan is "What do we do? What don't we do?", that should be a major hint to anyone. In an unusual subversion, they're not particularly evil or corrupt, just occasionally secretive. They usually cooperate with the FBI investigations and offer valuable resources for most cases, and their head, Nina Sharp, is a classic case of a Red Herring (in that she's never guilty of anything, and is usually just trying to help). There is, however, to consider the alarmingly high number of evil bioweapons, immoral experiments and Mad Scientists that were once part of their research, before being closed down, dismissed or fired from the company. Amusingly, their founder, William Bell, only turns evil in the timeline when he's no longer CEO of the company.
Vexcor in Charlie Jade is the largest and most prominent of the five Mega Corps that run the Dystopian parallel world the protagonist is from.
Captain Sheridan makes an offhand reference to "Disney Planet", implying that the Walt Disney Company is dabbling in planetary government by the 23rd century.
Explained in the Expanded Universe: Walt Disney Company bought a lifeless moon in the Orion system and is making a theme park out of it. So far they only built one city-sized domed attraction, but is already a huge financial success.
Edgars Industries, "the biggest biochemical conglomerate on Mars." William Edgars specifically enlightens Garibaldi about the real power in the Alliance. One of the major reasons Clark is giving PsiCorps extraordinary powers is because he is worried of the amount of control exerted by the Mega corps and want to return the power to the politicians... well specifically to him.
William Edgars: The Megacorporations have been in charge for years.
In DAAS Kapital the world was run by the corporation-government Shitsu Tonka, which has declared history officially over and all art dangerous.
How I Met Your Mother, has the company that Barney works for, Altrucel. They are implied to make all sorts of weapons for war, but want people to remember they make the yellow fuzzy stuff on tennis balls. Altrucel later acquired an ailing Mega corp, the fictional Goliath National Bank. It's taken to the extreme in one episode:
Marshal: This is a bit out of my league. For one thing, if these contracts aren't executed exactly, I think we're at war with Portugal... Barney: Please, that's just Tuesday for me. (shreds contracts)
The Colbert Report: Stephen often shills for The Prescott Group. A shady conglomorate with companies such as Prescott Pharmaceutical, Prescott Oil and Prescott Finance.
Total Recall 2070 has each branch of industry apparently dominated by a single Megacorporation each. Rekall does information technology, Uber Braun robotics (and androids), Minacon produces energy and raw materials and so on. Interestingly, Uber Braun may be based off real-world consumer electronics company Braun, which is now part of real-world mega corporation Proctor & Gamble, so maybe Truth in Television.
Kings features CrossGen, a corporation so powerful that its backing can (and has) unilaterally put someone on the throne of Gilboa. During the course of the series, its CEO makes other demonstrations of its vast power, singlehandedly bringing the nation to the verge of bankruptcy and blacking out half the countryside with a single phone call.
Torchwood: Miracle Day has Phicorp, a major pharmaceutical company, which later starts pretty much running most of the world. Of course, it's later revealed that Phicorp is actually innocent, as one of its chief executives has no idea what's going on. In fact, the entire thing is being run by the Families who have somehow grown from three mobster groups to running the world.
Stargate SG-1 has the Tech Con Group, a major conglomerate on Hebridan that makes a wide range of products, owns the planet's major TV station, and runs a lottery. They are not specifically referred to as evil; in fact their ads during "Space Race" are played for laughs, since they apparently make everything from engine parts to funeral arrangements.
In Kamen Rider Gaim, there is one called the Yggdrasill Corporation, which has its HQ be a building in the shape of a giant tree and ruling the city of Zawame with an iron fist. Its figurehead leader, however, insist that it's not an all-imposing company but rather a foundation dedicated to the betterment of humanity.
In Helix the action is set at Research Inc. Arctic Biosystems, who are "big pharma," in-universe, and must be rich indeed to afford an arctic Elaborate Underground Base base that can house and employ over 120 people. They themselves are a subsidiary of the even bigger Ilaria Corporation.
The World Company in the French satirical puppet show Les Guignols de l'info is a generic evil corporation in which every single Corrupt Corporate Executive is a dead ringer for Sylvester Stallone. The Stallone puppet was originally used for any generic war-mongering American General during the first Gulf War; after the end of the war, a sketch showed him having turned to the private sector and it stuck.
In Misspent Youth by Robert Bohl, you play bomb-throwing teenage anarchists in a Dystopia with an Authority that is out to personally destroy them. Groups who choose to play with a Corporate Authority frequently create evil megacorps.
Hudson-Cosmos, Stahl, Phi, Trilex Pharmaceuticals and... too many others to name, in Cosmopol. Most people are not aware that Hudson-Cosmos and Stahl actually outright own almost all of the other companies and the entire cities that they are based in.
Pentex, in the Old World of Darkness. They're a front for the embodiment of entropy and its efforts to poison the entire universe. They have hands in everything from fast food to toys to pharmaceuticals to energy to firearms to Role-Playing Games — in fact, most people in the setting don't even know Pentex exists, or if it does, that it's simply an independent entity without any ties to its constituent companies.
The New World of Darkness has the Cheiron Group from Hunter: The Vigil, a gigantic multinational organization that controls a dozen front businesses. One of those departments hunts, captures and studies supernatural creatures, both to find new product possibilities and to utilize their powers (by harvesting bits of them) for the company's own use. Their employees are given a handbook containing near-useless information as their only guide to what they're dealing with, so turnover is insane (giving the player characters a job opening).
Warhammer 40,000 has several interesting examples. Economic cartels like the DeVayne incorporation are more powerful that most governments on provincial worlds, they have private armies and small fleets to their name, more than enough to conquer a backwater world. However, all that power amount to nothing compared to that of the feudal orders of the Imperium.
Shadowrun has ten Mega corps that produce nearly all the goods and services one can find in 2070. Interesting in that real-world corporations such as Microsoft and Wal-Mart are included in the Shadowrun universe, but are decidedly inferior in size and influence compared to any several dozen other businesses. It's established in the backstory that the Grid Crash in 2029 massively weakened the existing corporations and made them very vulnerable to aggressive newcomers as well as forcing mergers and buyouts that made the Big 10 what they are. BMW was bought outright by the great Dragon Lofwyr and formed the early backbone of Saeder-Krupp. Ford and most of the other American auto companies were bought or merged with Ares. Sony is still fairly strong in Japan, but has shrunk to the status of a regional company that has spent the last few decades just barely avoiding being bought out or taken over.
Microsoft was almost killed overnight during the Crash but managed to hang on as the third tier cyberdeck software maker Microdeck (still run by the Gates family too); the third edition even made a plot hook out of them and possible ties to the Otaku. The company heir-to-be has been exploring the Matrix since his infancy. One story posted by a Shadowland runner says that he struck up a virtual relationship with her; for several weeks, he knew the exact right things to say, the right buttons to press to come across as her ideal man, etc., until she finally broached the idea of meeting in person. At that point, he abruptly ended the relationship and ceased contact. Pissed off at being played for a fool, she spent months tracking him down, eventually discovering that he was a pale, teenaged boy who had spent almost his entire life in the Matrix with absolutely no physical social experience. He had spent weeks studying everything about her on the Matrix and used that information to construct the persona of her perfect man, but panicked at the idea of speaking to her in person. Out of pity and/or disgust, she left him alive.
Interstellar corporations in Traveller, such as GSbAG, Hortalez et Cie, Sternmetal Horizons, Ling-Standard Products and SuSAG. Traveller megacorporations make good foils, and can potentially add drama to a Free Trader centered game. Alternatively in a court intrigue centered game they can be among the things a PC princeling has to take account of. The nobility and the megacorporations are interlaced subtlely just as the nobility are interlaced with the Imperial government.
The Alternity game's Star*Drive setting. The following Stellar Nations, which controlled large regions of space, all fall under this category: Austrin-Ontis Unlimited, Insight, the Rigunmor Star Consortium, the Starmech Collective, and Voidcorp. Although not all to the same degree — Austrin-Ontis have gone so far into One Nation Under Copyright that they are more nation than copyright these days, whereas Voidcorp is all about profit.
In SLA Industries, the eponymous Mega Corp effectively constitutes a state; its numerous subsidiaries (some big enough to be Mega Corps in their own right) compete with each other in a kind of internal market. Real competitors Thresher Inc and DarkNight Industries are corporations in name only, operating as paramilitaries opposed to SLA.
The Crysalis Corporation from Cthulhu Tech, a game best described as an unholy lovechild of the Cthulhu Mythos and Neon Genesis Evangelion. The corporation produces everything from household supplies to military hardware. In addition it secretly strives to dominate the world, supplying various cults and terrorist organisations and creating mutated creatures to fight for it. Furthermore, its CEO is actually an avatar of the god Nyarlatothep disguised as a mortal man. Talk about a Corrupt Corporate Executive!
The setting Eberron has the 13 Dragonmarked Houses, Dungeon Punk equivalent to Mega Corps, each with their own specializations (Entertainment & Espionage, Banking, Consummer Goods, Private Security, Animal Breeding, Notary, Prospecting, Magical Detections, Overland Travel & Teleportation, Overseas & Air Travel, Hostelling, Healing). Each house descends from a bloodline blessed with a dragonmark, a unique set of birthmarks that grant them powers and skill bonuses relating to a particular theme. Each family used their advantage to corner the market on a particular good or service, as no non-dragonmarked could really match them.
Elsewhere in D&D, the Mystara setting's Minrothad Guilds are a nation, made up of several islands, that's organized like a huge corporation. Each island, and each race that lives there, operates like a manufacturing division of the company, while the fully-incorporated "service guilds" are the equivalent of government departments (defense, etc.).
Hard-science RPG Blue Planet has several Mega Corporations that are states unto themselves called Incorporate States. Given that Earth itself is a Crapsack World in the Blue Planet universe, the Incorporate are very interested in the colony of Poseidon where the game is set.
In Mutant Chronicles, the big powers of the solar system are called "mega corps" and fit pretty well with this trope, but in a slight aversion they have by now evolved into Feudal Future noble houses of a sort. Exceptions are Capitol, which is still technically a corporation, and hence a democracy of sorts — you have one vote per piece of stock you own, and the company president serves the same role as an American president. There's also Cybertronic which is focuses on creating electronics and cybernetics, it does have bits of an Orwellian society style.
In Eclipse Phase, the Mega Corps that were unable to adjust to a post-scarcity economy died out while those that could evolved into the Hypercorps. Most are small and decentralized, often existing wholly in Cyber Space (as labor is almost fully automated), but hold a great deal of influence in the Inner System. Mars is run wholesale by the Planetary Consortium, which poses as a republican democracy, but whose power is divided proportionally among the hypercorps who own shares in it. Venus used to be under Consortium rule until the habitats formed the Morningstar Constellation almost by accident.
Exalted has a high fantasy example in The Guild, a vast trading concern that uses mercenaries and assassins to dispose of its rivals, is the world's biggest trader in narcotics and slaves, and sells live humans by the thousands to the Fair Folk who devour their minds for food. And because that isn't evil enough, they buy the emotionless unfeeling husks back from the Fair Folk so they can be resold as obedient manual labourers. The Guild also distributes medicine (when it's profitable), and by selling the soul-eating trickster fairies meals, they hold back a second Balorian Crusade... well, except the one time they nearly started it, but that was an accident.
Cyberpunk 2020 with Arasaka and MiliTech as the two most prominent examples, the former pure evil and the latter unscrupulous but not as evil.
ComStar in BattleTech holds an absolute monopoly on interstellar communication and has a sizeable army of its own. Since the fall of the Star League they've been somewhat monastic.
The Guilds of Fading Suns are descendants of the Second Republic's megacorps who adapted to a Feudal Future. The massive corporations essentially ran both Republics.
A number of these exist even on post-apocalypticRifts Earth. Triax of of the New German Republic, the Cyberworks Aerospace Networks on the Moon, plus numerous smaller megacorps in the Republic of Japan. Elsewhere in the Megaverse, most notably in the Three Galaxies, you have Bushido Industries, Galactic Ship Corporation, Hartigal Combine and Naruni Enterprises among others. Any given Splugorth realm could be considered a megacorp as well given their brand of alien mercantilism.
Call of Cthulhu supplement The Fungi from Yuggoth. New World Incorporated (NWI) is a large international corporation that has interests in mining, oil, aircraft manufacture and ship building, international banking and munitions. Unknown to the general public is the fact that NWI is controlled by the forces of the Cthulhu Mythos and is being used to bring about the Day of the Beast and cause worldwide devastation.
In the Card Game Netrunner and it's rerelease AndroidNetrunner one of the players controls an evil mega corporation that controls most of the world by force or by controlling the goods they sell the people. Haas Bioroid creates androids and new technology for robots. Wetland Consortium has built the space elevator which becomes part of the story line for the game. Jinteki works in the computer and Internet industry. And NBN controls the news showing.
Ace Combat 3: Electrosphere: Features this in the form of General Resource Ltd. and Neucom Inc., who are at war with each other at the start of the game. The series returned to national conflict setup with 04, but chillingly, 5, Zero, and particularly Advance gives General Resource a Start of Darkness, having them start from a humble arms company called South Belkan Munitions Factory, later Grunder Industries. Neucom, meanwhile, started off as the Erusean Air and Space Administration, the clandestine organization behind the high-tech gadgetry of Eruseans in the aforementioned 04, including the famed superfighter X-02 Wyvern. In fact the entire series between Electrosphere and the Continuity Reboot with Joint Assault (except maybe 6) can be safely considered one giant prequel to the Usean Corporate War.
Alien Swarm: SynTek Megacorporation Incorporated. They own a star system, including several mining colonies, a penal colony, and a space station. They also own several planets and mining colonies outside their star system and several fleets of starships used to transport employees (dubbed colonists) and materials to and from their colonies. Ontop of that, they make everything from medical supplies, to food and drink, to weapons. There is also United Industries and the Telic Corporation, both of which are just as big as SynTek.
Alpha Prime: The Company. They seem to be responsible for a wide range of things in this universe, including mining for a substance that's used in everything from beer to positron brains. They're also corrupt beyond belief, willing to sacrifice the lives of their employees for a chance at a veritable Philosopher's Stone, actively engaged in the eliminating of all witnesses of their conspiracies, able to hire exceptional lawyers and assassins, and they have a private group of marines to enforce their will.
Aquanox: Has EnTrOx, which stands for "Energy, Transportation, and Oxygen" (the latter is misnomer, since you can't breathe oxygen at the huge pressure of ocean bottom depths). They provide energy for underwater colonies, ultra-fast submarine transportation (thanks to their marketed supercavitation drives), and Helium 17, a breathable gas that allows humans to survive on the ocean floor. Basically, no one can touch them without running the risk of being cut off from anything that allows humans to survive in this hostile environment.
Where every faction you work for (except for your mercenary organization, a terrorist group, or the mercenaries themselves) are these. According to the backstory, in most of the continuities, the corporations also serve as the government.
For an example, in the first series is Chrome, with its Chemicaldyne subsidiary. Opposed by another Mega Corp, Murakumo Millennium, who has no qualms about contracting a terrorist group, known as Struggle, to carry out their plans. A third, smaller company called ProgTech is introduced in Master of Arena, but is shown to be a benevolent actor as opposed Chrome and Murakumo.
Armored Cores 2 and Another Age introduce their successors, Zio Matrix, Emeraude, and Balena corporation. Unlike the rest of the series, The Government has re-asserted itself in the 2 games, so the corporations aren't as all-powerful as they once were, but they still get away with waging unchecked wars against one another. Zio Matrix even goes to war against itself, when Zio Matrix Mars goes rogue and Zio Matrix Earth obliterates it.
The third series continuity sees Crest, Mirage, and Kisaragi. At first suppressed and kept in check by a supercomputer AI, they grew large (well, Crest and Mirage does, Kisaragi crushed in-between) after they broke free in Silent Line, Nexus introduces a new corporation, and Last Raven sees all companies band into one.
The fourth in the series has the various companies destroy the various nations of the world in what is known as the National Dismantlement War and establish "Pax Economica", where survival depends on peoples' loyalty to a company. Ten years after that, in For Answer, they form the League of Ruling Companies, which still rules the world and has these companies band together to become a single superpower, in theory, at least.
Assassin's Creed: Gives us Abstergo, a pharmaceutical company on the surface which functions as the modern day front for an Ancient Conspiracy. Lucy Stillman mentions that her inability to be taken seriously after she finished college — and thus her inability to find a job until she was approached by Abstergo — was likely a series of failures specifically designed by them so she would have nowhere else to go for employment. She further assures Desmond that while this may sound ridiculous, they can do it. They also trace Desmond via his motorcycle's registry, apparently without going through the police. This is taken even further in the sequel, where through a series of mad revelations, you gradually find out that Abstergo, under one name or another, has been manufacturing all important technological or political progress for centuries.
BioShock: Has Ryan Industries, Fontaine Futuristics and Sinclair Solutions.
There are plenty of examples to list, so here they are:
Atlas. They make powerful firearms, maintain a private army outfitted with said guns and other Atlas Artillery, and control most of Pandora, notably T-Bone Junction. They also fail propaganda forever. It does what most big corporations in-game do-build infrastructure on new planets. Unfortunately while it does make good-quality firearms (which are often overhyped, with the exception of the Atlas Chimera Revolver™ and Kyros' Spear™) its soldiers are competent, and it can effectively build colonies on planets, its management is idiotic. How much? A three-year-old admiral is put in charge thanks to "Goddamn Nepotism," it's full of cheerful and pointless Comedic Sociopathy, and the propaganda department is full of card carrying villainy.
The Hyperion Corporation, who owns the New-U and Catch-A-Ride stations, and makes the Guardian Angel Satellite. They're described in-game as a multitrillion-dollar company, and they're possibly the most advanced. They make robots, entire cities, resort towns, assorted industrial structures, they have mining operations on Pandora, and as of Borderlands 2 are actively making war against the entire planet of Pandora. Most of what they make has aerodynamic, space age designs, and has a clean, geometric look to contrast with Pandora.
The Dahl Corporation, who also makes guns, (unlike Atlas, they have an inspiring and awesomeBadass Creed. Also, they're the largest weapons producer on Pandora.) claptrap repair kits, wind turbines, and can finance the mining operations for a colony which, by the way, the also financed themselves. They seem to be the Black Mesa to Atlas's Aperture Science facility. They've built an enormous dam that makes the Hoover Dam look like a child's plaything, and seem to be the most average of all companies both in terms of advancement and the fact that their tech wouldn't look out of place in the modern day.
The Jakobs Corporation, which is very retro, very steampunk-ish. Aside from making Wild West-ish hunting-quality sniper rifles, semiautomatic rifles high-poweredrevolvers, and shotguns it looks to be in on the colony supply industry, making prefab housing and fuel tanks. They also made a small town for the workers employed to make their guns, and control most of the wood production on Pandora. Despite being (outwardly) one of the least advanced, they're implied to be Hyperion's biggest rival.
Torgue, however, differs from literally everyone in that they have based their strategy on pure 'MANLINESS... and actually succeeded. Their guns have extremely high caliber barrels and are adorned with danger markings and checkerboard patterns, sort of resembling guns from a 90s comic in their patterns and oversized builds (think Rob Liefeld or Tank Girl), making some fans say the Torgue Corporation must be run by either Saxton Hale or Ork Boyz (the second game proved them completely correct, as their CEO mister Torgue is an Idiot SavantAdult Child who likes to blow stuff up). They have the money to put huge tournaments on other planets, and also manufacture radios and motorcycles. They also own an interplanetary TV station, which is used to televise said tournament.
Tediore, like everyone else here, also makes firearms, including Outrunner artillery. Also, instead of reloading these guns, you throw them and they explode, which fits perfectly with the "character" of the company: the weapons are basically "convenience" set: not particularly notable in terms of states, but extremely cheap bordering on disposable, hence why when you're out of ammo, you chuck the gun rather than reloading it normally.
We're not sure what Maliwan, S&S, and Vladof do, though logic states that Maliwan, considering their involvement in incendiary weapons, may have had something to do with climate control in the cold years of Pandora. Maliwan makes elemental weapons, and seems to be the futuristic hippies/artists to Hyperion's futuristic corporate. S&S has bullets. Vladof is Russian-themed and arms revolutions.
By Borderlands 2, Atlas and S&S Munitions are out of business. In the former's case, Hyperion has taken over the role of the villainous megacorp under the leadership of Corrupt Corporate Executive and douchebag extraordinaire Handsome Jack, who is essentially waging a war against the entire population of Pandora in a hunt for an ancient Vault. The latter has since been put out of business by local bandit-made guns, which replicate the S&S gimmick of "more ammo!" at a much cheaper price.
City of Heroes: Crey Corporation. One bit of dialogue says that they have products in 90% of Paragon City's homes. Indeed, they're so large, they're able to fund their own massive army of "security personnel". One thing that doesn't quite make sense, though, is how they were able to achieve this level of market saturation in what is suggested to be maybe a decade at the most (extreme corruption notwithstanding).
Command & Conquer: The FutureTech Corporation in Red Alert 3. In the original Red Alert 3, it is simply mentioned in the background for being the company responsible for technologies such as the Mirage Tank and the Chronosphere. In Uprising, they are a minor faction in their own right and are implied to be in near-complete ownership of the Allied military as well as being engaged in a conspiracy under the Allies' nose.
Crackdown: The Shai-Gen Corporation and also the Agency itself.
Crusader: The World Economic Consortium, bad guys in this series, are the Mega Corp — a conglomeration of several economic bodies who themselves rose to power and prominence as traditional governments failed in their area at the end of the twenty-first century. The WEC extracts everything, refines everything, manufactures everything, packages everything, sells everything, employs everyone. And they brook no red ink in the bottom line.
Dark Fall: The Hadden Corporation, source of paranormal-detection gadgets in this game series. Not nearly as big as most examples, yet its director's influence over events is vastly out of proportion to this company's modest size due to his apparent access to prophetic powers and/or time travel.
Descent: The Post-Terran Mining Corporation. All they do is mining, but they control dozens (that we see) of incredibly large mines in at least eight star systems (likely more). They also have their own mercenary force, which is large enough that the combined Sol System military considers it a legitimate threat. The corporation's CEO, Dravis, makes it no secret that he is a Corrupt Corporate Executive.
Page Industries, a true Mega Corp with major roles in (at least) network communications, space mining, and heavy manufacturing; and its subsidiary Versalife, a massive pharmaceutical company with political power because it's patented the cure to The Plaguewhich it also produces. These accumulated their power, technology, and R&D expertise as arms of The Illuminati before their owner, Bob Page, splintered off to pursue his own ends.
Sarif Industries in Deus Ex: Human Revolution is close but not quite a Mega Corp., as it loses in the bio-augmentation market to Tai Yong Medical, who has cornered the market and has performed a lot of illegal research. The latter also has ties to the Illuminati.
Mods for DXThe Nameless Mod and 2027 feature WorldCorp and Human Horizon. In TNM you can either join or fight WorldCorp. Human Horizon in 2027 is hunting you down for a better part of the game.
Doom: The Union Aerospace Corporation (UAC) from the series, whose experiments in teleportation technology were responsible for all Hell breaking loose. By Doom 3 one of their catch phrases is "The UAC is making safer worlds through superior firepower." The opening scroll from Doom 3 sums it up nicely:
"The Union Aerospace Corporation is the largest corporate entity in existence"
"Originally focused on weapon and defense contracts, new ventures have expanded into:"
"And other scientific endeavors"
"With unlimited funds and the ability to engage in research outside of moral or legal obligations"
"The UAC controls the most advanced technology ever conceived..."
The Elder Scrolls III: Morrowind: Has House Hlaalu, a high fantasy megacorporation that belongs to the Dunmer royal house. The other Houses are less mercantile and don't resemble corporations, they are respectively a warrior aristocracy (Redoran), a feudal magocracy (Telvanni), a church (Indoril) and plantation slave owners (Dres).
Has Sigma Shipyards, an engineering corporation based on the Kane Band around Earth whose main business is constructing and upgrading starships. The company also controls its own shipping line and supply chain. Sigma also has control of what's left of the hypergate system. Interestingly, Sigma is portrayed fairly positively: a former member of the board of directors now works for the Rebellion against the Federation and the Bureau, and the company provides surreptitious backing to the Rebels.
The original Escape Velocity had the Astex Mining Corporation, a typical evil megacorporation that works directly for the Confederation. There's Starbound Shipping, United Galactic Express, and Consolidated Express, none of which are evil, but are big enough to wage open war against each other.
The Caldari State. The entire faction is composed of a handful mega corporations. All aspects of society are run by the corporation. Citizens are born into a corporation and effectively work there for life. Getting fired is not much different that getting shunned from society.
All the other space-based corps are also mega corps of varying shadiness from "very" to "not much" and wield significant pull; a group of Gallente megas recently stood up against an attempted government takeover and succeeded.
Final Fantasy VII: Shinra, which produces electric power, military hardware, Materia, and automobiles, among other things.
Armacham Technology Corporation is a company primarily focused on aerospace technology and weapons development. However, said weapons development programs include armies of cloned supersoldiers and telepathic commanders, and ATC itself maintains a series of massiveunderground bunkers and a private army that could probably take over a medium-sized country if it felt like it. A company with the same name and logo appears in the video game Shogo: Mobile Armor Division. It is also heavily implied that Shogo is in the same timeline as F.E.A.R. making the two Armacham Corporations one and the same.
The third game in the series gives a good look at the scale that Armacham operates on. The first two levels take place in an unspecified Latin American country where ATC operates a huge private prison, and ATC mercenaries walk the streets of the city in full uniform with armored personnel carriers, attack helicopters, and heavily-armed robotic weapons platforms engaging in a running gun battle witht he Point Man with total disregard for the local population. Later on, ATC has an army occupying the city of Fairport where the first two games took place.
Fur Fighters: The Big Bad sent up his own vast Mega Corp at some point and it's shown throughout the game at many points doing many different things. Presumably Viggo got the money for everything from getting advanced technology from the dinosaurs (don't ask) and then decided to bid massive air-craft-carries and submarines to conquer the world.
Several of these, but the most prominent one was the Crayven who was the main pusher for colonisation, had a military force that rivalled (or even surpassed) the government of Earth, produced everything and had more or less free reign in the frontier colonies. In addition to that, their leadership was ruthless, uncaring and dabbled with ancient and potentially deadly alien technology with little heed to its results.
Another Mega Corp called Wellby-Simms is mentioned in the background. Crayven bought its weapons from Wellby-Simms and Ground Control 2 implies that of all the original Mega corps, Wellby-Simms was the only one that managed to survive the rise of The Empire by turning itself from a weapons manufacturer to a manufacturer of industrial and mining supplies.
All There in the Manual: not only is the government of Earth at the time of the first Ground Control essentially a council of Mega Corps, the Order of the New Dawn is — legally speaking — one as well.
Also in the same universe with Portal; hardly anybody important in the universe apart from Chell has notworked for Black Mesa at some point. One of the slides from a projector in a meeting room shows that Black Mesa clearly controls the market that they are competing for. It insinuated that Aperture Science has high goals but never actually delivers.
Word of God and supplementary material suggests that Aperture Science simply cannot market itself. Its products are at least as good as Black Mesa, but between demanding ridiculous amounts of funding, staying in Beta far too long, ruining its reputation with misapplied human experimentation and trying to sell world-changing inventions for ridiculously near-sighted functions (e.g. using an extradimensional gateway device as a shower curtain (somehow)). Granted, the CEO wasn't exactly the sanest of men...
Immortal Souls: Has the Isis Corporation, a mostly benign organization of vampires and other supernatural creatures that controls the shadow underworld. Though they're more concerned with simply keeping the balance between the shadow creatures, the Templars, and the regular humans, than doing active good.
Imperium Nova: Houses can seem more like this than feudal nobles. Especially those operating in the mercantile, transportation, technology, financial, geological, or military spheres. To be more specific, in most Feudal Futures a house owns a planet or an area on a planet, in this game houses only rule planets if they enter the Politics sphere and have one of their members (or more often hired retainers) run for senate. In addition houses can build facilities on any planet within range of their homeworld. When you add that in at least one galaxy The Emperor is an elected position the eponymous imperium sounds more and more like a Federation run by corporations, like the U.S. except the CEOs have titles like "Duke" or "Marquis" and are allowed private armies.
Killer Instinct: Has Ultratech, a megacorporation that has replaced all world governments. They kidnap an alien to extort his participation in a fighting tournament, bring demons to earth from other dimensions, manufacture evil-looking military cyborgs, and are bioengineering a velociraptor-human hybrid, among other things.
Knights of the Old Republic: Czerka Corporation, shown as almost always being on the bad-side, and they're too big for Authorities to handle and police themselves.
Bokamba-Mercer, which even operates the police department. "Our duty is to protect, serve, and inform you about the marvelous new products available from Bokamba-Mercer!"
The game also has Bingo! corporation and, in the sequel, WATIcorp.
Marathon: The Game ModMarathon Rubicon features a Mega Corp. called Dangi which, to probably no one's surprise, turns out to be attempting to blackmail the human race into giving it complete control with a highly lethal virus. They also collaborate with a race of alien slavers. One of the game's possible endings ends with them successful; the other two end with them destroyed in different ways.
ExoGeni is the primary funder and supplier of human colonization in the Galaxy. They usually chose planets that are promissing for commercial exploitation with the colonists serving as a free labor force to build the infrastructure ExoGeni needs to start operations. To the top-level management, they are also good test subjects to discern the potential applications for the strange phenomena their scout teams detected.
Binary Helix is a major human biotech company that has been bought up by Big Bad Saren to work on two secret major bioweapon projects for his army. The first one bred an army of alien insects that had been thought to be annihilated thousands of years ago from an egg found preserved in ice. While able to hatch a queen and breed drones, they never managed to emulate the telepathic control of the queen, which didn't stop them from releasing them on unsuspecting colonies and military installations to judge their effectiveness. The other project was to develop a cure for the geneophage that kept the population of Krogans from exploding. While able to create clones, they were engineered to be a perfect slave race to obey Saren, which made the "cure" not an option for the Krogans. Since Saren was well known for having a special hatred for humans, he probably bought the company after both projects were already running.
While the full extent is never known, a significant number of major companies are actually owned and controlled by Cerberus. Instead of relegating any task to contractors, the Illusive Man simply buys companies to produce anything Cerberus needs. The profits from the companies also provide the almost unlimited funds at Cerberus' disposal.
Mass Effect 2 gives us Elkoss Combine, a volus Mega Corp which produces, amongst other items, weapons, food, omni-tools, medical and beauty products. An ad on Illium advises users of one of their beauty products that uses sonic waves to cease using it immediately. Another ad mentions one of their weapons, which also uses sonic waves. Even better - Those two are the same ad, and its implied that the beauty product and the weapon are one and the same.
Metal Gear Solid: The Patriots count as this. They are a secret organization that runs the American Government from behind the scenes deciding everything from who gets elected into Congress to who gets to be the President of the United States and have a firm control of the CIA and the Pentagon who conduct their secret Military operations and projects funded with massive stashes of secret cash that can't be tracked by the legal government. They control all the media that the American people consume, everything from literature, TV, movies, and Internet is all filtered by them for your enjoyment and have all the major corporations in their back pockets which influence the government and the average citizen. They are also implied to have international reach as they have secret bases which are mentioned in the story in China and Russia. Plus all the technological achievements they have accomplished, they have engineered clones from Big Boss's DNA which Solid Snake and his two brothers are the result of, have conducted genetic engineering which is capable of improving a human being into a super soldier, created super-powered exoskeleton suits that are akin to Iron-Man that can give a man super-human strength and speed, and massive bi-pedal, walking, nuclear-launch capable battle tanks known as Metal Gears. Stuff like this would run the U.S Government's economy into the ground but the Patriots seem to have no trouble funding these projects.
Nexus: The Jupiter Incident: hHas a number of Mega Corps, and the game's backstory reveals a war between the corporations and the IASA, which the corporations won, essentially abolishing all regulation beyond the Moon. The protagonist, Marcus Cromwell, works for SpaceTech, a relatively minor Mega Corp.. On one occasion, two OSEC ships ambush an IASA ship in deep space, proving that they can do whatever they want without repercussions. The most powerful Mega Corp. is the Kissaki Syndicate, a Japanese corporation that has managed to make enormous advances in the recent years (thanks to Imported Alien Phlebotinum). The status of the Mega Corps is unknown after the events of the game.
Persona 3: The Kirijo Group. Company high school, hospital, police...they're also a Yakuza clan, but in Japan there isn't really that much of a difference.
Franchise/Pokemon: All the Pokemon shops in the first 4 generations of the game and their many spinoffs are all run by the Sliph Corporation. Meaning they run the only store in 90% of the towns across multiple continents and island chains. They appear to maintain several crushing monopolies. If you want a Poke Ball you either buy it from Sliph or get this one old guy in Azalia Town who carves them out of nuts to make you one.
Sliph Corporation's only competition appears to be the Devon Corporation, which runs a few stores in one region.
If GLaDOS is to be believed, Aperture Science. The Aperture-branded cans of beans found in secluded places throughout the game would seem to support this theory.
This is a Subverted Trope in the sequel, where Aperture Science was revealed to be in severe financial straits. Aperture started as a Mega Corp. (in shower curtains) and lost its billions of dollars of financial success due to investing in scientific pursuits. The player can easily see why as they explore the facility; Cave Johnson seems to have made everything needlessly dangerous as part of a "Science Adventure." Many of their products are extremely dangerous as well, like the mobility gels being extremely toxic, (and intended for use as a pudding substitute). The turrets seen throughout the facility were intended to Protect Children by shooting child nappers. If that wasn't enough the turrets are fitted with an AI capable of making its own decisions, and can thus can decide to shoot people marked as friendlies, which they never do in game (though you would not be able to tell) but the box they are shipped in warns of. So after a long line failed products and an incomprehensible number of lawsuits Aperture is just flat out broke.
Along with Gadgetron in the (SolanaGalaxy), Vox Industries in the (Shadow Sector), and Grummel Net in the (PolarisGalaxy). Slight subversion in that every game has at least ONE Mega Corp, but they're not necessarily the same Mega Corp - they just control different galaxies / portions of space thereof.
Resident Evil: The Umbrella Corporation. Their front is a pharmaceutical company, but their real business plan consists of "let's inject this zombie potioninto an animal and see what happens" while giving OSHA the finger. Notably, when the government finally had evidence of Umbrella's misdeeds in the Time Skip before Resident Evil 4, they destroyed the company by applying a massive embargo to its activities, crashing their stock prices and eventually running Umbrella out of business. Years later, its Suspiciously Similar Substitute, TRICELL, suffered much the same fate after the main people behind it were killed in the events of Resident Evil 5 (it's heavily implied that the remainder of the company didn't survive the investigations prompted by the clues Chris and Sheva uncovered in Kijuju).
Re VOLUTION: The Corporation. It has taken over every facet of life. Apparently, it performs government duties as well as making products. It has a project called "New Breed", that will supposedly make people into superhumans. Jack Plummer, a mere janitor working for this group, is chosen as the guinea for this project and without his permission.
Saints Row 2 and Red Faction: The Ultor Corporation. It is also heavily implied that Saints Row is in the same timeline as Red Faction making the two Ultor Corporations one and the same.
The Secret World: Features the Orochi Group, a multinational MegaCorp with fingers everywhere. One contact points out a subcorporation manufactures the cell phone keypad that scans her fingerprints dozens of times a day, and its CEO may be exactly a Fallen Angel. Unusually, it's treated ethically ambiguous, and many mission contacts are Orochi security trying to clean up after the mistakes of executives or other parts of the corporation, while a number of investigation missions show more evil groups in turf fights with Orochi locals. It's also exceptionally incompetent: players will regularly pass by piles of dead Orochi Red Shirts at failed expeditions that unleashed horrific elder evils, and all the Orochi Group's information gathering techniques fall apart since they lack the tools to search or index the resulting database.
Sid Meier’s Alpha Centauri: Morgan Industries owns a faction of the game. It's also a Shout-Out to Microsoft: compare MS's nineties slogan "Where do you want to go today?" with Morgan Industries' "Where do you want your network node today?" An "economic victory," achieved by cornering the energy market (requiring an initial expenditure of enough energy to have used mind control on the entire planet and taking twenty years), which can theoretically be achieved by anyone, would be an even more extreme version.
SimCity: Omega Corp, slowly taking over all the businesses in a region.
Si N and SiN Episodes: Emergence: SynTek is the name of the villainous Mega Corp.
Star Control 2: The Crimson Corporation owns everything on all Druuge planets. If you get fired, breathing becomes theft of corporate property and grounds for execution. Furthermore, they are the extreme example when it comes to considering your employees expendable. Druuge ships can reload their power supplies by throwing extra crew members into the ship's reactors. In the game this translates to being able to sacrifice hitpoints to restore power.
Syndicate: EuroCorp is one of a number of global mega-corporations powerful enough to control whole areas of the globe and maintain covert(ish) cyborg agents with no fear of law enforcement. EuroCorp are a minor player in this field at the start of the first game, but by the end they own the entire world, and in Syndicate Wars they've been ruling the world for some time.
TriOptimum, where the "tri" stands for military/science/consumer...that's an evil combination in any setting. Mega-corporations dominated the System Shock world in general and national governments were very weak, but the corporations were greatly undermined by the events of the game. The world population rose against the massive corporate corruption responsible for the Citadel Station scandal and reinstalled The Government as the Unified National Nominate to regulate what remains. By the time of the second game, TriOptimum was on its last financial legs before an employee invented a working faster-than-light drive. In predictable corporate fashion, as many corners were cut from the ship built around the drive, to the point where the engines leaked constantly. Then the captain brought some alien life forms on board. And you, a UNN soldier, have to fix all of this.
The company isn't inherently evil, though. In the first game, their internal investigations were cracking down on Edward Diego for corruption, they provide you with all the intel they can gather from the outside and get through to you and eventually give the go-ahead to blow up the entire Citadel Station (mentioned to be a trillion-dollar investment) to destroy SHODAN. In the second game, the highest TriOp official aboard, Anatoly Korenchkin, is shown to be amoral, greedy and imprudent, but the crew logs also show that this means he is constantly butting heads with more level-headed company personnel.
Tachyon: The Fringe: The mega corp GalSpan "The Galactic Spanning Corporation" does not have a monopoly on every product ever made, but it certainly eclipses the other companies featured. Those smaller ones make the parts of your ship. Galspan doesn't worry about such trivialities, despite maintaining it's own military fleet; they mine stars. For the main section of the campaign, they are one of your two options to take for exclusive employment as a contract pilot, and through morally dubious means, their game ending is the only way your character can ever return back to Earth. Post-game Bora missions put you through some rigamarole towards the effect, but there isn't any definite mission or clue in the audio files that say the Bora get you back to Earth again.
The Guilds in Tales of Vesperia are like this, but are actually one of the rare benign/benevolent versions. The Guilds are essentially businesses made up of people who decided to leave the Empire, forfeiting their rights as citizens but allowing them freedom from the Empire's restrictions. The Guilds themselves are arranged in a hierarchy, with the Five Master Guilds at the top and one person (called the Don) leading them.
A small version of this trope is seen in Tales of the Abyss with Chesedonia. Chesedonia is a neutral land that most people go to conduct business and trade in. Despite an apparent lack of government, they seem to do a pretty good job of handling themselves, it's implied that Astor, the richest man in the city, is able to run things when necessary. In this game; the Mega Corp actually is merely an implication and is more of a third-party, along with Daath.
Tekken: The Mishima Zaibatsu and the G Corporation.
The Special Mission in Tenchu 3: Wrath of Heaven, which happens Twenty Minutes into the Future, deals with one: Rikimaru is thrust into the future, where a large biotech pharmaceutical company has made millions by selling a cure for a virus they themselves spread, and even though the fraud was found, the evil CEO bribed his way out of jail.
Tyrian: Microsol controls vast amounts of spaceship technology and can pretty much do what they want, they regularly invite around other companies to show them how far behind Microsol they are. They also gained complete control of the ice cream market.
Warframe: The Corpus, one of the enemy factions, control every major trading route in the Solar System, and have a monopoly on manufacturing goods. They're noted in-universe to be patterned off of medieval Merchants' Guilds. While they don't actively war with the other faction, the fascist Grineer, they will open fire on anyone who trespasses on Corpus property or interferes with their harvesting of rare, ancient materials.
Wasteland Empires: This Facebook game has Omega Corp. They were involved in everything before the Depopulation Bomb and released a virus that turned some of the population into slime coated mutants-in fact, they likely caused the destruction of the world in general.
The various goblin cartels in are Dungeon Punk versions of the Mega Corp, offering all variety of arms, Applied Phlebotinum, and services equally to all comers. The Steamwheedle cartel is the largest of the goblin cartels, and has a huge monopoly on goblin business. Despite being the largest, they're actually a little more... benevolent than most Mega Corps often are; as they're often giving the players jobs and money. The only way they would be out to kill the player character is if they decide to join the Bloodsail Bucaneers or Player Versus Player inside the neutral zones. (Course, most of the people who do this are Griefers...)
And then there's Venture Co, who are a much less morally ambiguous version of this trope. They're strip mining the mountains, polluting a few of the only oases in the Barrens, and, if you do the rogue quests, are developing a necromantic plague that will ensure its workers are efficient and compliant by turning them into zombies.
The Cataclysm expansion introduces the neutral-turned-Horde aligned Bilgewater cartel (well, it was mentioned in one small blurb in an RPG book before), who are another rival corporation to the Steamwheedle cartel (even in footballbomb). They controlled the entirety (as far as what you can visit) of the goblins' home island of Kezan, which was covered in massive factories. After losing two zones to volcanoes, they industrialize and/or strip mine most of Azshara, and many other smaller locations (for the Horde).
Xenosaga and, by extension, Xenogears: Has Vector Industries (simply called "The Company" in the XenogearsPerfect Works book). Vector makes everything from starships to cellphones, has a branch on every inhabited planet in the galaxy, holds conciderable sway over both the local and federal governments of the Galaxy Federation, and has been around for (at least) 7000 years. They have a rival corporation called Hymas, but Vector actually owns them too!
Zork: In these games, by the end of the reign of King Dimwit Flathead the Excessive, every single zorkmid of commerce in the entire country was controlled by FrobozzCo and its various subsidiaries, which were all named The Frobozz Magic <Insert Product Name> Company, which was run by Dimwit's younger brother, John D. Flathead.
The Suburban Jungle had MegaHugeConGloMaCo, which was acquired by Amalgatronix Corporation. From the FAQ:
What does MegaHugeConglomaCo do, exactly? They merge with, take over, or establish corporate relationships with other huge companies with similarly vague names.
The closest Freefall has is Ecosystems Unlimited. They control most of the colonized planet, own most of the robots, and one of the main characters' species (and they owned her too until they sold her). This may be due to the planet not being terraformed yet, so it's not very populated, and E.U. has to be there for the terraforming to be done: It's their job, after all.
Breakpoint City has Sploz Co, makers of everything from advanced holography operating systems to fat-free yogurt. They provided the funding to build the titular city, and have their headquarters there.
The Maytec Consortium of S.S.D.D essentially owns California, has a standing army, and claimed all of Mars (until the Anarchists went there and found better mineral deposits). They're essentially the third greatest superpower in the solar system, due partially to their selling weapons to both sides of the CORE/Anarchist cold war.
Mega Fun Food LLC from My Lifeat War is by inference a massive agriculture Mega Corp. They're wealthy enough to hire their own private army in the form of the 1st Investment Recovery Battalion.
Excalicorp in Arthur, King of Time and Space is a good Mega Corp, at least since Arthur started influencing policy. The strip doesn't directly state how big it is, but if you pay attention you'll notice that everything from computers to cars has a sword-in-the-stone logo.
Gencorp in Gengame seems to sell/produce everything we hear about or come across, to almost dystopian levels. However, because of the comic's generally light nature, this is more of a source of humor than anything.
In Quantum Vibe Earth is split between two gigantic Mega Corps, and all the other off-world planets and stations seen so far have been owned by corporate joint ventures except for Luna. Luna has had its government nearly-completely swallowed by Omega Tek. Joe's Diners and Muc Ar Foulain, from the asteroid belts and the L5 Colony respectively, are a lot less evil than the conventional Mega Corp, though.
Crockercorp from the new post-Scratch timeline in Homestuck. It's Betty Crocker expanded from baking goods to superscience, with handheld teleportation devices and telepathic personal computers. Rumors circulate that Betty Crocker herself is an evil alien "Batterwitch" controlling it all and trying to brainwash the population. They're right; she's actually Her Imperious Condescension, the troll empress having survived the destruction of the trolls' universe.
Goodkind International, in the Whateley Universe. They make a big deal about taking care of the "little people" and being a responsible corporation. But the CEO disinherited and disowned his own son when the boy became a mutant, and turned the kid over to a company mad scientist for experiments. They're also behind the highly anti-mutant "Humanity First!" organization and the main backer of the anti-mutant paramilitary Knight of Purity, as well major funders of the international Mutant Commission Office.
Open Blue has Remillia, essentially a nation whose main political parties are competing Mega Corps.
G-Corp from Gaia Online. Founded by death-fearing megalomaniac Johnny Gambino, and Badass Grandpa Edmund, G-Corp was responsible for a majority of Gaia's technological, scientific, and medical advances. Unfortunately, when Edmund left the company, things took a turn for the worse. Now everything G-Corp makes (from pet dinosaurs to hair growth formulas) has a penchant to go horribly, horribly wrong. (To put this in perspective, G-Corp has caused the Zombie Apocalypsetwice. In fact, zombies seem to be their chief product). Ironically, G-Corp is actually the good company. The evil company is NeXus, run by Labtech X. NeXus's sole purpose is to provide X with the means to take over the world. Their most famous achievement is using G'hi to create a self-replicating, almost invincible army of Animated. They also build a cool Underwater Base, a Humongous Mecha, and a Scarf Of Ass Kicking. G-Corp also has a copy in S-Corp, which consists of "Elftechs," and is owned by the Claus family.
Precision Horizons in Above Ground is an all-powerful corporation ruling the underground human community. The Guild plays a similar role on the surface of the planet.
Jib Jab's Big Box Mart counts in regards to big box stores like Wal-Mart and their negative effect on people.
In Orion's Arm the solar system was ruled by Megacorporations led by transapient AIs up until the Nanodisaster. Now Archailects control most of the population of Terragen space but Mega Corps still have a great deal of influence in the Non-Coercive-Zone (NoCoZo) and the Periphery.
TOAST Industries, from the Netland series. A rare heroic, or at least protagonistic (that is, they're against universal annihilation) example.
Futurama has Mom-Corp, a massive company that seems to have stocks in everything and a hand in every business, from Mom's Friendly Robot Company, to Mom's Babies Your Packages, with the joke rapidly expanding. It got to the point where the plot of a video game was that Mom actually owned over 50% of the planet and was legally able to turn the Earth into a warship to take over the universe.
Xanatos's company in Gargoyles. He's the wealthiest man, with the tallest tower, and several other "-est"s. The scary part is that the comic series is busily subverting this trope, as Xanatos is a raw recruit in the Illuminati, the group that secretly runs the world.
The Robotic Megafact Corporation in The Bots Master, also known as the "RM Corp", or simply "The Corp".
Charlotte is a CEO at Merge Corp in Rugrats. She describes it to Angelica as "a big monster that eats smaller monsters."
Harvey Birdman, Attorney at Law has Sebben & Sebben, the legal firm where Harvey works, which is later revealed to have sister branches that cover numerous products:
Narrator: The affiliated companies of Sebben & Sebben are leaders of industry worldwide: rice, soy, hemp, flavored breastmilk, LSD, breastmilk-flavored LSD, those twirly things on stripper's breasts, textiles, tiles, text, baltimization, and vintage pointed sticks.
