It's no surprise that dragons show up in many video games, now is it?
Lineage 2 usually (read: nearly always) follows the western style of dragons, despite this being a Korean game. Hey, it is a medieval European setting... Within this though are somewhat large variety of them. This goes all the way up to the terrible twosome, Antharas the green earth dragon, and Valakas, the four-winged red fire dragon. Both of them are, from the player's perspective, probably as big as oil tankers. And they're SHIPS, not trucks.
Lunar dragons resemble Western dragons (though with feathers rather than scales), but it's notable that young dragons look like small, winged cats. And apparently, they shit diamonds (At least the White one does. You might get Rubies/Sapphires/Onyx from the other three.).
The Dragon, Bone Dragon, and Great Wyrm/Entei in the Disgaea series are nothing out of the ordinary as far as dragons go appearance wise (The fact that they, among other things, go to high school and run for office, though...). But then there's the Serpent class of Disgaea: Hour of Darkness, a shark dragon (Which is what the class was called in the Japanese version), as well as the fluffy, angelic, dog-faced Holy Dragon, first introduced in Disgaea2, whom most probably wouldn't call a dragon until they saw its class name.
Lampshaded in Disgaea3 by its introduction lines to your other characters upon creating one:
Holy Dragon: I look like a dog, but I am a dragon! Don't get it confused. Woof!
Dragons and their relations to humans form the crux of many a Fire Emblem plot, save for The Sacred Stones and the Tellius games. The Akaneia games and its distant sequel have the biggest focus on dragons: in both Akaneia (and the Elibe games), the result of humanity becoming a prominent species forced dragons to take human form (and use magical stones to transform again), as the air had changed in the lands they had lived on. Many of the dragons either wound up dying out or they were hunted; the Earth Dragons are an extreme case, as all but one chose not to take manakete form, and they degenerated into madness. Word Of God put out that, on the order of the Divine Dragons, humanity (who already resented the Earth Dragons) took out the remaining Earth Dragons, which is why Medeus of the Akaneia games hates them so much. There are several dragon types:
There are the majestic Divine Dragons, which are the strongest of them all - the Divine Dragon god (albeit not in the traditional sense), Naga, has immense powers and is worshipped by humans. There are the Earth Dragons - very dinosaur-like in appearance (at least in the NES and SNES games), and they can plow through the earth; they were also the dominant species across the world prior to humanity. Then there are more "traditional" dragons, with Fire, Ice, and Flying dragons (also called wyverns), and finally, there's the unusual Mage Dragon, which is nigh invulnerable to magic attacks.
Final Fantasy VI had eight legendary dragons in the World of Ruin (which were simply Palette Swapped versions of other enemy sprites). Beating all eight would unlock a powerful summon that deals a lot of unblockable damage to everyone on the battlefield, your party members included, which was otherwise unobtainable. Of course, you had to be near the very end of the game to beat all eight dragons anyway.
Final Fantasy XI has several distinct types. There's the small baby wyvern that Dragoons get as a pet (that have arms), much larger wyverns (that apparently shed their arms as they grew) that are often encountered as high level normal enemies, and dragons that often have some magic and are only ever bosses (and are ugly as sin). Finally, there are wyrms, which are huge western-looking dragons that wield magic and are highly intelligent, and mostly represent one of the game's basic elements. Wyrms can take anywhere from 18-36 people to kill. Bahamut, incidentally, is also known as the Wyrmking who, as the name implies, rules over the rest of the wyrms. There's a battlefield where you have to face him and other wyrms simultaneously.
Dragoon's wyverns are actually baby wyrms, SE just added them before they had added the wyrms to the game. According to the game, the dragoon's wyvern "is marked with the holy crest" that makes them good, while shadow dragons and wyverns don't have the crest and are either evil or animalistic. The wyrms are benevolent and work for Bahamut, and one of the wyrms mentioned above was actually the wyvern of the last dragoon. (before the player characters, anyway) You fight them for convoluted plot reasons, this being Square after all.
Final Fantasy XII, meanwhile, classified all large reptiles as dragons, including the expected wyrms and wyverns, but also dinosaurs.
Almost all Final Fantasy games have Bahamut, one of the most reoccurring and strongest summons in the games. He's more western style. Also a longrunner is Leviathan, with an Eastern serpentine look, but just as powerful.
Compliation of Final Fantasy VII ups the ante with five Bahamut variations: Bahamut, Neo Bahamut, Bahamut Zero, Bahamut Fury, and Bahamut SIN, in order from weakest to strongest. They're all western style dragons, of course.
Istaria: Chronicles of the gifted: they are split into two factions, one faction (the Lunas)which wishes to dominate the Naka-duskael (the scaleless ones-any inteligent race who arent dragons) and one (the Helians) who wish to benevolently lead the world into a golden age through example (although personalities vary greatly from individual to individual. many humanoid-friendly dragons are in fact Lunas). uniquely for an MMO, Istaria's dragons are a playable race. They're western in anatomy and attachment to shinies, which is an actual gameplay element by way of the hoard stat, which affects several abilities and serves as a requirement for quite a few racial quests.
Jade Empire is a Western game, but its world is a fantasy version of ancient China, so the Water Dragon is wholly Eastern- she's the Goddess of water and responsible for shepherding the souls of the dead into the next life.
Pokémon considers "Dragon" to be one of the many elemental types that a Pokémon can have, but also features a few non-Dragon Pokémon who definitely fit the classical mold, namely Charizard◊ (Western)note While Charizard, by default, is not a Dragon type, it does have a Dragon-type Super Mode. and Gyarados◊ (Eastern, albeit with the behavior of a Western dragon). And there's also some Dragon-type Pokémon who are very different (Altaria◊). The Dratini line is a bit more ambigous as they're sea serpents, which have a bit of overlap.
There's also Aerodactyl. While it's obviously based on a Pterosaur, it looks more like a Wyvern. Lance owns one.
Likewise, several Legendary Pokémon are of the dragon-type. Namely Rayquaza (who is based somewhat on the appearance of a Chinese dragon and on the dragon of Hebrew myth known as Ziz.), Latios & Latias (Loosely based off of wyverns), and three of the "God Pokémon" from Diamond/Pearl/Platinum as well...Dialga, Palkia, and Giratina.
Arceus itself can become a Dragon-type if holding the Draco Plate.
Other Dragon-type Pokémon include Garchomp, a Land Shark with features of a fighter plane, and Kingdra, a gigantic seahorse which, according to its Pokédex, has the ability to cause whirlpools by yawning. Also Vibrava and Flygon, which appear more insectoid then dragon-like. Our Dragons Are Different indeed.
The Dragon craze isn't over. What are the cover legendaries to Pokemon Black And White? Not just Dragons, but Yin and Yang Dragons, being Zekrom and Reshiram, respectively (both Western in appearance but Eastern in behavior and motifs). Not only that, but the fifth generation also has:
An extra legendary dragon (Kyurem) to make a Fire, Ice, Lightning legendary Dragon trio that also can fuse with the two cover legendaries for two more cover lengendary variations,
A pure Dragon-type evolutionary line (Axew, Fraxure, and Haxorus) based on dinosaurs,
And finally, Druddigon, one last non-evolving cave dragon just for the heck of it. It's also the most outwardly Western dragon, being an ugly, unintelligent, savage brute with a very medieval appearance and characteristics.
Then we get into the sixth generation, which includes Noivern, a Flying/Dragon type which looks like a giant bat and uses sound-based attacks, Tyrunt and Tyrantrum, a Tyrannosaurus rex revived from a fossil, and Dragalge, a poisonous weedy sea dragon. Special mention goes to Goomy, an adorable little blob that eventually evolves into Goodra, a dragon made of goo. Depending on the circumstances, this can also include Ampharos, a sheep. However, said generation introduced a new type specifically to take down Dragon-types... Fairy.
The Draic Kin of The Longest Journey. They resemble the Western variety physically (although they can disguise themselves as humans) but have the nature-spirit culture of the Eastern dragons. In fact, they are actually aliens with powers akin to God who lived on Earth for over twelve millennia and helped humans to split the planet in two.
Those who know about the Draic Kin dislike the word "dragon", as dragons aren't real.
They also greatly vary in size. The Green, Red, and White Kin are all about the same size, maybe 3-4 times the size of a human. The Blue Kin, on the other hand, is truly gigantic and, apparently, the oldest. This would imply the Draic Kin keep on growing until they die.
Warcraft dragons look Western, and are primarily represented by five differently-colored groups of called dragonflights. The leader of each dragonflight is called an Aspect. Each Aspect is charged by the Titans with protecting a specific domain: Life (red), earth (black), nature (green), magic (Blue), and time (bronze). Some of the Dragonflights have become corrupted or mad over time. In Warcraft II all dragons were green and were your average fantasy dragons, only their leaders had actual sentience. They take on their current form after the novel Day of the Dragon in which they were based off the dragons in Dragonlance.
Red dragons are generally benign but are still predators (they have a burning hatred for orcs after being forced into their service in Warcraft II). Green are usually benign but rarely seen (some have gone insane). Bronze dragons are neutral. Blue dragons were neutral, until their aspect, Malygos, decided that all magic-users had to be killed and dragged the rest of the blue dragonflight down with him. Black dragons used to be good, but that changed after their aspect, Neltharion (now known as Deathwing), was driven insane from the whisperings of the Old Gods.
Naturally, there is plenty of opportunity to fight dragons in World of Warcraft, from whelps that are barely more than a annoying common enemy up to 40-man raid encounters.
An interesting variation are the dragonkin, which look more like lizards. They don't have wings but instead an extra set of limbs, except a few that have 6 limbs and a pair of wings. According to the official RPGs, they are former mortals who served the dragons so long that they took on their traits. They are usually found together with the whelp variety (adult dragons are fairly rare).
There are also drakonids, which are half-man, half-dragon creatures created in the laboratories of Blackwing Lair.
Though there are also drakonids that serve the other dragonflights and could not have possibly been created in Nefarion's laboratories. They have been stated to have naturally come about. Try not to think too hard about that one.
Maybe not, just look at Alextrasza's humanoid form and you will change your mind almost immediately.
Actually, Cataclysm shows that Drakonids can be formed from exposure to draconic energy, much in the same way that the dragonkin are made.
There's also wyverns, but they don't appear to be related to dragons in any way. They look like lions with batlike wings and a scorpion-like tail (your encyclopedia of mythology would identify these as traits more befitting a manticore). They are apparently quite intelligent and used by the Horde as flying mounts. As of Wrath of the Lich King, they can be tamed as exotic pets by high-level hunters who are specced in the Beast Mastery talent tree.
Players can use some dragons as mounts: There are nether dragons in Outland, introduced in the Burning Crusade expansion. These dragons descended from black dragonflight eggs that were caught up in the storm of energy that broke Draenor, and ended up with a strange physiology (almost shark-like heads, one-fingered wings like a pterodactyl, and a fin on the end of the tail). They are a faction that players can befriend, and after a lot of work, they can earn the right to ride one as a flying mount. As of Wrath of the Lich King players can win an Albino Drake mount after completing the achievement "Leading the Cavalry", which is given for owning a total of 50 mounts.
Dragons of other colors are also available as mounts in Wrath of the Lich King from several sources, usually as rare drops from various dragon raid bosses, though one is acquired by completing a timed event in a heroic 5-man, and another can simply be purchased from the Wyrmrest Accord rep faction at the maximum reputation rank. Strangely, Greens are the only dragons that cannot currently be obtained as a mount (even blue, black, twilight, and undead drakes, all of which the players are canonically at war with, can be obtained as mounts).
Proto-drakes also appear in Wrath of the Lich King; they are said to be the primitive ancestors of modern intelligent dragons and resemble the traditional depiction of wyverns (with tiny front arms like a raptor or T-rex), being the less intelligent cousins of dragons. They are obtainable as mounts via completing certain achievements, from a single rare spawn in Northrend that will always give the mount when killed, or as rare drops from certain bosses.
Which is odd, given that according to the lore the Titans created the dragons directly, to help battle the Old Gods. Which is made odder still by the fact that apparently all titan creations are made of metal, and the Aspects, who were supposedly made by the titans, are flesh and blood. Except Deathwing, who is evil.
Er, even Deathwing started out as flesh and blood. He got the metal makeover during the Second War, when goblins attached metal plates to his natural scales.
Actually, it has not been stated that the Titans created the dragons. The background seems to suggest they already existed when the Titans came, as the Aspects are described as being created by the Titans empowering already existing dragons. However this seems to have been retconned in Wrath of the Lich King, where it is stated that the Titans created the Aspects using the giant proto-drake Galakrond as their progenitor. Presumably they then created the dragonflights after the Aspects.
In The Elder Scrolls universe, the Dragon is the symbol of the Tamrielic Empire. Interestingly, although the Empire itself is styled after the historical Roman one, the dragons are definitely of Eastern variety, to the point that the Imperial Throne of Tamriel is called "The Dragon Throne", just like the one in Imperial China. There are also western style dragons in the earlier games, Daggerfall featured baby dragons as high-level enemies, while Redguard had you fight a fully grown one. There's also a story featuring western dragons.
Dragons in The Elder Scrolls series are considered extinct by the end of Tamriel's Third Age, though it is impossible to tell if that is absolutely true in any region except for Morrowind where it is known that Cliff Racers drove them to extinction. Even the baby dragons of Daggerfall's Illaic Bay region aren't relate-able to the one time a true dragon was seen in an The Elder Scrolls game - the one you killed in Redguard. Notably, however, one Daedric Princes often appears in the form of a dragon, and the lead deity of the Nine Divines is Akatosh, the Dragon God of Time.
In Morrowind, you had some items of dragonscale armour. M'aiq the Liar claimed that you can't see any dragons because they fly above the clouds, and those that fly lower are invisible.
They're back in Skyrim, thanks to the efforts of Alduin, firstborn of Akatosh, taking on the form of a dragon himself. It turns out that these dragons aren't your typical dragons, and are actually sort-of angelic entities/Physical Gods that cannot truly be killed unless there's a Dragonborn (One who is a Dragon soul in a mortal body) to absorb their soul upon death. Dragons also do not breathe fire or ice, but rather act as a sort of Reality Warper using shouted wordsin their language. Instead of breathing fire, for example, the dragon shouts fire-related words in its language and commands fire to appear. Physically◊, the dragons are "wyverns" - they have only four limbs; two hind legs and their forearms are actually their wings, like a bat. When walking on the ground, the dragons move in a fashion very similar to said bats.
Dragons were also technically never extinct, as a few of them were still around. The first dragon you actually fight in the game, for example, was hiding in Skyrim's mountains until Alduin returned, and another named Parthurnaax has been meditating on top of the Throat of the World since Adluin's defeat, teaching the Greybeards in the Way of the Voice.dMagi
One of the simplest potential theories about them is that Dragons are all fragments or shadows of Akatosh, the God of Time.
Nethack's dragons are kind of western — huge (as defined by the game's size logic), flying, and equipped with a different breath depending on their colour... and they look like capital Ds.
The Might and Magic series does the Western variation almost by the book. In the Heroes of Might and Magic games, they tend to be among the most powerful creatures, and many factions have some sort of Dragon as their strongest (tier 7) creature, such as Green/Gold Dragons for Rampart, Red/Black Dragons for Dungeon, and Bone/Ghost Dragons for Necropolis. Some of the games had even stronger neutral dragons.
In Might and Magic VIII there were playable dragon characters and were a major race in the game.
Might and Magic VI had a "promotion" quest for the paladin class whereby a dragon must be slain. It didn't do any good to go to the area that was swarming with dragons, though. You had to specifically kill a "named" dragon, of which there was, of course, just one in the game. (Truthfully, that dragon was no different than any other Red Dragon in the game aside from the fact that it did have a name; ironically, the fact that it was alone when you fought it made doing so easier.)
Also in Might and Magic VII, where it was the first stage promotion quest for paladins. Again, there was just the one of him. Later, candidates for the evil Druid stage II promotion, Warlock, had to find a dragon egg and get it hatched into a Baby Dragon. This time you did have to make your way through an area crawling with dragons and titans, and that was after you'd forged your way through a tunnel system infested with scores of some of the meanest monsters in the game.
In Dragon Rage the protagonist, Cael Cyndar, is a dragon.
Heroes of Might and Magic V, the latest in the series, features a pantheon of Dragon Gods. There's Asha, the Dragon of Order and creator of Ashan as well as the 8 Elemental Dragons, and her counterpart Urgash, Dragon of Chaos and creator of the demons. The Elemental Dragons are mainly worshiped by one of the remaining races each, and are likely the reason for the (lesser) Dragons being a rather common tier 7 creature for most of the races.
The Legend of Dragoon has some of the strangest variations of dragons imaginable, neither fitting Western or Eastern examples. These dragons vary from looking like giant insects, to giant catfish, to floating tanks. The only dragon that remotely resembles any more typical dragon at all would be the Divine Dragon, who is a massive, absolutely terrifying looking flying abomination that sacrifices traditional breath attacks for an extremely destructive cannon and missile like attacks.
Dragons in the Breath of Fire series are shape-shifters who spend most of their time in human form, sometime unaware of their true nature. The first two games feature exclusively Western types (though the Agni/Infinity dragon of the first game looks more like a lizard-centaur). The third game has mostly Western dragons, but a few special transformations (namely the fire/ice/thunder gene mix) are explicitly Eastern. The fourth game has mostly Eastern dragons, but the protagonist changes into exclusively Western dragons; they're also "Endless", the physical gods of that verse. Dragon Quarter goes all the way back to Western dragons exclusively (though, since there's only two dragons in the game, it's not that big a leap).
In Breath of Fire: Dragon Quarter the "D-Constructs" are apparently some kind of artificial life form that are able to fuse with humans and give them vast amounts of power at a cost of slowly taking over the body of their host, although the estimated chance to successfully complete the fusion is only 1/4 at very best. While they do look like normal Western dragons in their natural state (accomplished by either fully taking over their host's body either via repeated use of their powers or when the host dies in another manner), they appear as featureless black humanoids with Tron Lines running through them in their dormant state. It's also possible to forcibly implant parts of their dormant form into humans for a moderate power increase, but this also leads them into looking like a combination of a zombie and a battle-damaged Terminator. The successfully fused form, on the other hand, looks similliar to the Warrior form in the previous games of the series: humanoid in size and overall design, with scaled hands and feet and a pair of small wings engulfed in flames.
Ridley from Metroid is a space pirate dragon (and The Dragon in almost every game) that fits the Western definition on almost all points — he flies, he breathes fire, he seems to show up at least once per game regardless of how many times he's apparently been killed (the series has a chronology and no Reset Button), follows the six-limbs morphology, is fairly large, possesses weak points on his chest and in his mouth (only in the 3D games), and is generally guarding or hoarding something, be it a new route or a new weapon. The prequel manga explains Ridley's tenacity as the result of a powerful Healing Factor which lets him absorb the biomass of creatures he eats... including Samus's parents. The games never really show this (with the exception of Other M), but Ridley is also noted to be extremely intelligent, and holds a high military rank in the Space Pirate hierarchy. In regards of Metroid: Other M, Ridley is Little Birdie, a small beakless yet birdlike creature that the scientists of the space station were raising, not knowing what it was. It eventually shows it's true colors when it eats dead bodies and then screams at Samus, who seems even disgusted but leaves it alone as it seems to be harmless yet really isn't. Eventually its husk is found, and then a large Chameleon like creature attacks Samus, who's Husk is also found later, as Ridley molts to advance through stages of its life.
In Puzzle Quest: Challenge of The Warlords, you're led through a realm populated by Western-style dragons. One of whom you can optionally add to your party. You can also capture a wyvern for a mount.
There are also dragon spiders. The only thing they have in common with normal dragons is the ability to breathe fire.
Bowser, The King of Koopas. He is actually an ox-turtle. Shigeru Miyamoto first envisioned him to be an ox, but one of the other devs instead suggested making him a turtle. He still retains his ox-like features in his current design, making him look dragon-like. He also has the title of Daimaō in Japan, which means "Great Demon King", so maybe the Our Demons Are Different Trope would be appropriate for him too.
There is also Yoshi, although he's more like a dinosaur horse at first glance. However, under certain conditions, he can spit fire and grow wings to fly. There are also other breeds of Yoshi, sporting different colors, that present different abilities. In Super Mario World, the speaker blocks state that the Yoshi Coins are actually Dragon Coins.
Super Mario Bros. also has lots of actual dragons, both of the Western and Eastern varieties (and nearly all try to kill Mario). Hooktail and Gloomtail from Paper Mario are Western Dragons (evil), Bonetail is a skeletal Western Dragon, Fracktail is a malfunctioning robot Eastern Dragon, Wracktail is an evil robot Eastern Dragon, Bonechill looks like a skeletal version of Satan crossed over with a dragon and a giant cannon, Dragohoho from Mario & Luigi: Superstar Saga is Prince Peasley changed into a dragon.
The Super Mario Galaxy 2 Boss, Gobblegut is an Eastern style dragon with pretty much the behaviour of a Western style one, and is fought as a boss under the control of Bowser Jr. in his Fiery Flotilla level, as well as a fiery version fought as a secret boss in the Battle Belt Galaxy.
Rex looks exactly like a purple celtic dragon, yet is a dinosaur and can't breath fire, its unique trait is walking around as a pancake when jumped on. Reznor is a fire breathing Triceratops, Dino-Rhino and Dino-Torch resemble rhinoceroses yet can breath fire. This also extends to Dino-Piranha in Mario Galaxy, at first apparently a dinosaur version of Petey Piranha, yet it falls into Dragon territory when you see its counterpart Fiery Dino Piranha, who's on fire and can shoot fire and also leave a trail of it.
The Legend of Zelda has a handful of dragons as bosses. Both variants, no less. And some hybrids—Volvagia breathes fire and is a dangerous monster, and has a head like a Western dragon—but his body type and the way he flies suggest an Eastern dragon, Valoo has a more Eastern face but a Western body type, Argorok is more a Wyvern than anything and so is the One-Winged Angel version of General Onox. The Legend of Zelda: Skyward Sword features three dragons that have hominid faces and wear kimonos.
The dragons◊ of Panzer Dragoon tend to have the shape of dragons combined with an utterly alien physiology; the dragons are all bio-engineered weapons of war, and they breathe homing laser beams. All of the dragons in the games have odd, rock-like formations on their skin.
There's also Spyro the Dragon. In the original Spyro the Dragon game, there are five dragon breeds named after what job that dragon breed does: Artisan, Peace Keeper, Magic Crafter, Beast Maker, and Dream Weaver. The different dragon breeds all live in different realms and have different body types and horn shapes. For example, the large, stout Beast Maker dragons have thick curled horns and live in swamps while the spotted, muscular Peace Keeper dragons have straight horns and live in a desert region. All the dragons lay their eggs during the Year of the Dragon, and every dragon is granted a dragonfly, which in turn grants the dragons some of their magical power, when he comes of age.
In the Legend of Spyro trilogy, different colours tend to be representative of a dragon's element and they are usually only privy to one. Spyro himself is an exception, as he is a purple dragon, which in themselves are extremely rare (there's only been two in that world's history, Malefor (AKA, the Big Bad) being the other one, though he claims that there have been many). Cynder is an exception due to being exposed to dark magic throughout her life. Her appearance is rather unique among dragons as well, though this may be just a gender thing, since she's the only female dragon seen in the trilogy.
In the Monster Hunter franchise, most of the monsters one fights are Wyverns, bipedal with a long tail and claws on both wings.
The dragons of the series are quite varied, but extremely powerful; in-game they are referred to as Elder Dragons. All but two monsters titled as Elder Dragons have four legs, wings, and can deal dragon-based damage (which is also the element they are weakest to). This means the more traditional fire-breathing dragons such as Teostra and Lunsatra, and the god-like Fatalis and Alatreon, are in the same category as the sand-swimming giant, Jhen Mohran. The classification is also used for monsters that share certain characteristics as dragons, but do not fall into any specific category. The way it is used in-game, an Elder Dragon is best described as a UMA. The main examples of this are Kirin, basically a thunder-horse, Ceadeus, a horned whale, and Yamatsukami, a gigantic octopus-like monster, as they are considered Elder Dragons.
Raviente is the only Elder Dragon that is distinctively based on the Eastern dragon. White Fatalis is a sort of combination of both, its body shape is Western but many of its detailed features, such as its face, are that of the Eastern dragon.
"Wyvern" in Monster Hunter is almost that world's term for "Monster". Nearly every main monster in the series is classified as a Wyvern of some kind.
"Bird Wyverns" are either small Wyverns with bird-like features (like beaks and feathers) or Dromaeosaurs the size of shipping containers,
"Flying Wyverns" are larger, more dragon-like Wyverns.
"Pseudo-Wyverns" tend to use their wings as forelegs, and often resemble real-live animals like panthers and Tyrannosaurses.
"Piscene Wyverns" are amphibious monsters that often resemble fish.
"Leviathans" are also amphibious, but built more like crocodilians.
"Brute Wyverns" are more Tyrannosaur-like Theropods.
"Elder Dragons" come in all sorts of sizes and shapes, but they're all extremely powerful.
In Heart of Winter, the expansion of Icewind Dale, the source of all the trouble turns out to be a dragon's ghost. Apparently, she had been killed sometime before, and her spirit trapped by the sword that broke off in her heart. When the sword was removed, she escaped, possessed the body of a recently deceased barbarian chief, and began working to bring the Barbarian Tribes and the Ten Towns to war. She also killed her mate and ripped the souls out of her own offspring so that she could have a body. Her motivation for all this was that she "had a broken heart".
Chrono Cross features six elemental dragon gods, who are all pretty standard Western dragons (except for one, who is a female human sized and shaped harlequin with a french accent. They fuse together to form a protoplasmic WMD created by dinosaurs in another dimension.
The Sky Dragons in Cave Story are unintelligent winged reptilian fire-breathers. They're also a bit on the Super-Deformed side.
Dragons in Dragonseeds were cloned from fossils discovered in ruins, and come in a wide variety. Apart from the traditional Saurian and Winged varieties, there are such oddities as crabs, bees, one-eyed golems and animated coffins.
The "Super" forms of these dragons all resemble humans.
The first No More Heroes has a lightsaber dragon thatcomes out of a lightsaber. You don't get to fight it, though. In the sequel, there's Ryuji, with a full dragon theme to complement Travis's tiger motif. And a lightsaber dragon of his own, which you do get to fight.
The Battle For Wesnoth had normal western dragons along with the Drakes. The Drakes basically can be described as "Magical Samurai Dragon(Western) Blacksmiths". They are a sentient race of dragons that have a warlike way of life that follows a strict heirarchy code of honor (you have to be the strongest warrior to be the leader, and dirty tricks such as poison and stealth are disonorable for them). They are powered by an internal magical flame that would consume them when they die. They are also famed for their craft in creating Armour.
One of the expansions for The Sims, the original, Makin' Magic, let you hatch your own small dragon for a pet and they come in three colors, Red, Gold and Purple. The Red ones...well, hope you have a fire alarm handy.
The RyuOhKi (Dragon God Machine) of Super Robot Wars, one of the few Choukijins (Super Machine Gods) built by humans to protect the Earth and resembles the Eastern variety. What's unique is this machine is also the KoOhKi (Tiger God Machine) and can combine with a Super Robot and absorb its characteristics to become the RyuKoOh (Dragon Tiger King) and KoRyuOh (Tiger Dragon King), respectively.
Dragon Age has dragons of various stages in life. Dragonlings are hatchlings, and relatively easy to kill. Drakes are older and a bit tougher, and are about the size of a van. They're flightless, and the final stage of maturity for the males. Females grow wings and become much larger, becoming a typical western dragon, and there's one more stage where they become even stronger. They have the intelligence of a dolphin, and the fully grown females are on par with boss battles.
Also, Flemeth has the ability to turn herself into a dragon.
The Old Gods of the Tevinter Imperium, according to the Chantry and other sources, are deities that appeared to the Tevinter as full grown dragons. Unusual in that they were apparently male and sapient — the Tevinter mages claim that the Old Gods were the ones who taught them the secrets of magic. They were Dumat the Dragon of Silence, Zazikel the Dragon of Chaos, Toth the Dragon of Fire, Andoral the Dragon of Chains, Urthemiel the Dragon of Beauty, Razikale the Dragon of Mystery, and Lusacan the Dragon of Night. One Tevinter archon claimed that Dumat, the most powerful Old God, taught him Blood Magic. According to the Chantry, The Maker sealed the Old Gods deep within the earth for all eternity. Unfortunately, the Darkspawn are drawn to the Old Gods' song and work tirelessly to find them. When they do, the Taint immediately corrupts the Old God and turns it into an Archdemon. It is the twisted will of the Archdemon that unites all of the Darkspawn hordes in a Blight, and slaying the corrupted dragon god is the only way to end it.
The series actually gets its name from the specific in-lore dragons, in a way. Every hundred years in the Chantry calendar is considered an Age, and is named at the end of the previous Age. In 8:99 Blessed, several High Dragons, which were considered extinct, appeared, ravaging several countries. The leader of the Chantry was ready to declare the Sun Age, but, upon hearing of the dragons' return, declared the Dragon Age, and foretold it as a time of blood and chaos. Shewasn'tjoking.
The same setting also has wyverns, "cousins" to the local dragons. They can't fly or breath fire, but they're just as vicious and they spit deadly poison (which particularly adventurous nobles use to brew a Fantastic Drug).
For a good reference, one of the awakened dragons was mistaken for a mountain range in the original Guild Wars.
The dragons in the sequel are very different from most other dragons. Rather than just being giant, winged lizards, they're more like incredibly powerful EldritchAbominations. For example, one of them turned a huge stretch of land into a crystal wasteland while simultaneously mutating its inhabitants. How did it do this? Through some powerful spell? Some elaborate ritual? No. By flying over it.
Mega Man 2 has a Western-styled robot dragon, who breathes fire (and is weak to boomerangs upside the head).
Chinese-style dragon robots show up as normal enemies in the shooter segments of Mega Man 8. The blue ones mind their own buisness, but the green ones chase you around, gaining speed if you shoot off some of their body segments instead of hitting their heads. As it reuses many enemies from the aforementioned game, Mega Man & Bass also has the green ones as a seldom seen normal enemy.
Mega Man 9 has a Chinese-style robot dragon as a recurring miniboss. The weirdness comes from the fact that its body is made out of regenerating fireballs that can be destroyed up to reveal that nothing but bone beneath. Only hitting it in the head will accomplish much, though.
A somewhat Chinese-styled dragon was an extremely rare virus in the second game of the Mega Man Battle Network series and provided a powerful battle chip that would summon said dragon from a hole to hit every enemy on the field. A different variety of very Chinese-looking dragon appears in a select few areas in the sixth game and usually keeps most of its body hidden in a jar, only emerging completely to attack.
Mega Man Star Force has Dragon Sky, a Chinese-style dragon who's an alien hailing from the same destroyed homeworld that Geo's partner Omega-Xis does. If you're playing his associated version of the game, you can both borrow his power in battle and fight him as one of the game's ultimate bosses.
The third game has an electrical Chinese-style dragon as a normal enemy. Its gimmick is that its three regenerating body segments need to be shot away before you can reach its head and damage it properly.
Mega Man X 4 has Magma Dragoon, a humanoid dragon robot who's a Shout Out to Akuma in his character, appearance, and fighting style. There's also a less noteworthy giant dragon robot who's fought as the introductory boss.
There's a statue of a dragon in the Human Village that predicts the weather - thanks to kappa technology - and there's a palace in one of the regions of the Heavens called the Dragon Palace, though it seems to be in name only; noble Celestialsand Tenshi l
Not so much, apparently, the "Highest God Of Illusions" (AKA, Gensokyo's God) is simply called "The Dragon" and in fact was the dragon that helped in the creation of the Hakurei Barrier, the "Dragon Palace" in Bhava-Agra makes much more sense, since Bhava-Agra is essentially Gensokyo's Heaven, they'd be pretty much the ones to hold the Palace towards Gensokyo's God.
As of Wild and Horned Hermit a dragon finally makes an appearance. It's an Eastern style dragon that is apparently still a child. It's one of Kasen's many pets and she can summon him by creating a lightning storm (as the dragon literally materializes out of lightning). It has only served as a mode of transportation for Kasen so far.
A popular recurring fan theory is that Hong Meiling, the lazy Chinese gatekeeper of the Scarlet Devil Mansion, may be a Chinese rainbow dragon (hong lung) in disguise. That she uses rainbow-themed spellcards fits the theory.
There are only six dragons in Rift, and each one is only a manifestation of the leaders of the Elemental Planes.
The second Tomb Raider game has this in form of the power granted by the Dagger of Xian, which can turn people into dragons. However, the result is a clumsy, fire-breathing dinosaur-like Chinese dragon.
Sacrifice's dragons are the highest-level creature available to Persephone, the goddess of life and nature. They look like a green and short-necked dinosaur with feathered wings. They are sentient, intelligent, and good-aligned, and their Breath Weapon breathes life that is able to resurrect dead beings. They attack with their powerful bite.
The first boss of Kirby's Epic Yarn is a green dragon named Fangora who blows flames, flaps his wings to blow Kirby backwards, and sticks out his tongue in the form of a spear and shoots it at Kirby. His tongue can be used against him when he tires himself out. He is later brought back by Yin-Yarn in the final boss battle.
In Magic Carpet, dragons are fairly low-level enemies that look like flying caterpillars and shoot fireballs. On the other hand, the wyverns that you encounter much later look like traditional dragons.
In the Disciples games, the dragons are of your typical Western variety, although there are multiple kinds with different types of Breath Weapon: Black with acid breath (Death), Blue with steam breath (Water), Green and Red with fire breath (Fire), and White with vapor breath (Air). The Undead Hordes also have reanimated dragons in the form of Deathdragon, Doomdrake, Dreadwyrm, and Wyvern. All the dragons (except for the undead ones) are ancient and intelligent creates and are one of the first created in Nevendaar. Also, it is claimed that the Greenskins were created by a dragon deity.
Dragon Quest IX features several dragon-like monsters one can fight. The most prominent dragons, though, are two Eastern-style dragons. The first is Graygnarl, a large white dragon who guards a town. He acts noble and tough, but that goes away when he gets drunk. The other dragon is just a black Palette Swap of Graygnarl, who rivals him and also serves as the mount for one of the bosses.
Dwarf Fortress features the western type of dragon. They can breathe fire, hoard gold, and are the largest beings in the game. Only one thing is missing : as of the current version, they cannot fly.
Academagia's dragons are a mixture of Eastern and Western in appearance and mostly Western style in personality, with a healthy dose of Abusive Precursors. They are probably extinct on the surface of the world and not very numerous in the floating islands of Elumia (much to the relief of the human population).
The dragons of Dark Souls have stone scales and four wings, and were overthrown by the gods to establish the Age of Fire. They were all The Ageless, intelligent, and Word Of God describes them as half living creature half Elemental Embodiment. Drakes/wyverns are stated to be distant relatives of theirs, but only have a pair of wings and legs and seem to be like any other monster (no apparent intelligence and they probably age). Both can also have significant individual variation:
The Gaping Dragon, boss of the Depths, is a tainted dragon that has a gaping maw in its ribcage which spits out acid.
Seath the Scaleless is a white, scaleless dragon with transparent butterfly wings. He breathes cursed crystals as an attack, and regenerates health like lightning until you destroy the Primordial Crystal, source of his power.
The drake on the bridge breaths fire and is very large. The drakes in the Valley of Drakes are about eight feet tall (hunched over) and breath lightning.
Black Dragon Kalameet and the dragon from the trailer of Dark Souls II represent another, yet unknown type of a dragon. They appear more like the drakes with just a single pair of wings but Kalameet is stated to be one of the ancient dragons by Hawkeye Gough. Their distinguishing feature is that they only have a single eye located on their forehead.
Dragons are at least capable of interbreeding with humans, although the offspring of such unions are viewed as abominations. The only one encountered in-game is hiding in an alternate dimension within a painting and doesn't want anything to do with anyone from the outside.
Minecraft has an enderdragon. It's a western-type dragon who doesn't breathe fire, but can fly and phase through terrain as it is nothing. It evaporates any material not native to The End realm.
In Shining The Holy Ark one of the main characters is a dragonman. Half dragon half human, best not to think how that came about.
Whereas Shining Force III has many different types of dragons. Your army will often be fighting wyverns you do at one point fight a baby dragon. If you avoid the fight with the baby dragon you'll be able to recruit a friendly dragon in the second game, kill the baby and you've got to fight an adult dragon to get past.
The iPhone-game Dragon Vale has you running a dragon-zoo/conservatory, so needless to say, it contains an enormous number of very different dragons, divided into 8 elements with various hybrids, seasonal variants, and a couple of 'special' types. The sheer variety indicates a lot of brainstorming-session along the lines of "What would a Plant/Cold dragon be? What about a Lightning/Plant? Or a Water/Metal?" ...the results being a Lichen Dragon, a Cactus Dragon and a Rust Dragon, respectively.
One interesting detail: While the majority of the dragons are either some variety of Western, or completely unique, there is only a couple of dragons that fit the 'Eastern' pattern - and those are some of the rarest and most valuable dragons around, specifically the Luck-Based Mission Rainbow Dragon, and the golden Leap Year Dragon which was only breedable for about a week around leap-day... and won't be available again for another 4 years.
There's also the Panlong Dragon, whose egg features a Chinese character. It looks exactly like the Rainbow Dragon except for the color pattern. Interestingly, its victory animation after winning a race has it rapidly stomping the ground with alternate paws while moving its head up and down. If you've ever seen a Chinese festival, this is exactly what those large dragon puppets do.
There are also one or two multi-headed dragons, which are more reminiscent of Russian dragons.
In E.V.O. during the reptile stage the player can eventually mix and match the available evolved parts to become a dragonlike creature, but eating a red crystal found in a secret area temporarily turns the player into a true westen style dragon.
The RTS game Seven Kingdoms, among its "Greater Beings", includes both Western (Norman) and Eastern (Chinese) dragons. Instead of the passive effects of the other beings (healing your troops, reducing opposing kingdoms' loyalty, etc.) these two are full-on attackers who will burn every enemy they find to death.
The Thief stealth game series has burricks. They're wingless reptiles with the size of a pony and the outward appearance of a chubby theropod dinosaur and are apparently the closest thing to a dragon in the Thiefverse. Expectable in such a down-to-earth Low Fantasy setting. Burricks aren't actually ferocious (being herbivores), but they can still be dangerous. No, they don't breathe fire - instead, they burp cloud after cloud of some sort of highly concentrated fumes created in their digestive system. The fumes are corrosive and you'll suffocate in them almost immediately. It's implied they have slightly explosive properties - Garrett makes a snappy remark in the second game about how "infiltrating Shoalsgate is like looking down a burrick's throat with a lit match". Burricks appear up-close-and-personal in several levels of the first game and in the form of hunting trophies and occasional references in the second and third game.
Rune Factory Oceans has the Claw Dragon, the Gold Dragon. Those you can keep as "pets". Then there's the wish fulfilling Arch-Dragons. the one that's in the egg that Tallyn leaves behind after she leaves can talk, while he in the egg! Through Odette!
Dragons are considered Fantasy in Dra Koi, which means they can only be hurt by other Fantasy like a legendary hero or a mad scientist's superweapon. They have human intelligence but an odd worldview and seem to exist purely for the point of metafiction.
Though not a dragon outright, Songbird of Bioshock Infinite was conceived to be one, and in many early concepts was a dragon and to varying degrees a cyborg, (in the end he may be all machine). He fills the role of a classical dragon as well, guarding a girl who is actually something of a princess in a tower. Coincidently, he also is closet we get to The Dragon of the game.
In Phantasy Star Online 2, the planet of Amduscia is populated by a variety of different dragonkin, such as the humanoid Dinians, the horse-like Nordirans, and the ape-like Baridrans. The boss dragons are no less varied, among them the western-styled Vol Dragon, the crystalline Quartz Dragon (Who's also got jet thrusters in its wings), the bizarre Dragon Ex (Who's packing an additional set of limbs that double as shields and swords), and the downright alien Chrome Dragon. All of the dragons save for the Chrome Dragon are telepathic, as well, which gives them their ability to provide Boss Banter and conversation in story scenes (As well as giving them some serious cases of mental Vocal Dissonance).
In the Borderlands 2 DLC Tiny Tina's Assault on Dragon Keep, the dragons that appear in the campaign are "wyvern"-style enemies who come in shock, fire, corrosive, or slag elements. They're also constantly flying, making them hard to kill (especially for melee characters). Later on, there's a sidequest to fight a raid boss consisting of four of these dragons attacking you at once.
