*** Ultimaya Tzolkin looks identical to the benevolent [[BigGood Crimson Dragon]] from the anime, but has a completely different role in the manga story and it is also blatantly malevolent. It also has a OneWingedAngel form, "Ultimate Phantasmal God Ultimitl Bishbaalkin", a far more demonic looking dragon that serves as the boss monster of the manga's BigBad.

*** The DiscOneFinalBoss Dr. Faker's true ace monster is "Number 92: [=Heart-EartH=] Dragon", a gigantic black and purple that resembles a {{Dracolich}}.

*** "Red-Eyes Black Dragon" is a mild case of this, being an entirely black-scaled dragon with [[RedEyesTakeWarnining red eyes]], and being first introduced by the minor antagonist Dinosaur Ryuzaki (his Serpent Night Dragon also fits this trope). However, Ryuzaki loses "Red-Eyes" to Jonouchi, which would continue to act as a heroic dragon for the rest of the series while displaying less demonic traits in ''Duel Monsters''. Its BreathWeapon "Kokuendan" translates to "[[{{Hellfire}} Black Fire Bullet]]".

** ''Anime/DigimonAdventure'': Two of the Dark Masters, Mugendramon and [=MetalSeadramon=], are based on dragons.
** ''Anime/DigimonTamers'': Guilmon and his evolution Growmon are referred to as Demon Dragons (Dark Dragons in the English localization), and are red Virus-type dinosaur-like dragons that specialize in combat. Upon extreme anger of Takato over the death of Leomon at Beelzebumon's hands, he transforms his partner Guilmon into one of these, named Megidramon. His powers are so acute and massive that he causes the Digital World to slowly crumble around him simply by existing. Fortunately he's calmed down before he could destroy everything.

A subtrope of OurDragonsAreDifferent, OurDemonsAreDifferent, and ScaledUp.

* ''Fanfic/ThomasAbridged'' [[spoiler: The Malevolance’s original form before it was 'killed' was a jet-black dragon.]]

** ''VideoGame/XenobladeChronicles3'' features a number of Dragues/Draguils, with the most significant being the {{Superboss}} Dreadwyrm Nizoont in the Lower Maktha Wildwood.

* ''VideoGame/XenobladeChronicles1'' has only three dragons, but they're the strongest group of monsters in the game, with the latter two dragons even dropping [[{{Hellfire}} Demonic Everflames]] once defeated:
** Dragon King Alcar is the antepenultimate boss of the story, guarding the way to the roof of Prison Island, serving as almost a literal example of TheDragon due to it blocking the way to the BigBad's realm.
** Demon King Dragonia attacks Colony 6's ether planters once it reaches 90% completion and must be defeated as a result.
** Avalanche Abaasy is one of the {{Superboss}}es, appears at night on Valak Mountain during a raging blizzard and is ''the'' most powerful enemy in the game.
* ''VideoGame/XenobladeChronicles3FutureRedeemed'' features as its most powerful {{Superboss}} a Fogbeast Draguil called Fogdweller Abaasy, fought in the same location as and using similar moves to the aforementioned Avalanche Abaasy.[[note]]Depending on one's interpretation of the exact nature of Fogbeasts, it potentially ''IS'' Avalanche Abaasy.[[/note]]
** ''VideoGame/XenobladeChronicles3'' itself features a number of Dragues/Draguils, with the most significant being the {{Superboss}} Dreadwyrm Nizoont in the Lower Maktha Wildwood.

** Demon King Dragonia attacks Colony 6's ether planters once it reaching 90% completion and must be defeated as a result.
** Avalanche Abassy is one of the {{Superboss}}es, appears at night on Valak Mountain during a raging blizzard, and is ''the'' most powerful enemy in the game.

* While Bowser tends to flirt with this trope due to being a draconic turtle monster who rules over a near-literal [[LethalLavaLand Hell on Earth]], he goes all in with it in the ''Bowser's Fury'' expansion for ''VideoGame/SuperMario3DWorld''. There, he takes on the form of a jet-black kaiju-sized monstrosity called Fury Bowser, who will occasionally awaken and go on violent rampages that turn the peaceful Lake Lapcat into a dark and stormy hellhole while he assaults Mario and Bowser Jr with volleys of massive spikes from his shell, storms of enormous fireballs, and jets of fire reminiscent of Godzilla's atomic breath. He's also constantly secreting an inky, tarlike substance that turns out to be [[spoiler:paint from Bowser Jr's magic paintbrush that reacted strangely to an angry outburst]], which mars the lake's beautiful scenery and is very dangerous to touch.

** ''VideoGame/TheLegendOfZeldaTearsOfTheKingdom'': [[spoiler:Ganondorf himself is well-known and well-feared as the Demon King. In the final battle, in a last ditch effort to defeat Link and destroy Hyrule, he swallows his [[AmplifierArtifact Secret Stone]] to sacrifice his own mind and become a dragon. His boss title even becomes "Draconified Demon King, Demon Dragon."]]

*** During Vector's final duel, he summons "Chaos Number 5: Perishing-Gloom Dragon - Chaos Chimaera Dragon", which is the evolved form of the unseen "Numbers 5: Perishing-Gloom Dragon - Death Chimaera Dragon". "Chaos Chimaera Dragon" is gigantic red and black {{Dracolich}} and serves as Vector's new boss monster.

*** The Duel Dragon counterpart to Jack's Red Daemon's Dragon is "Jeweled Demon Dragon -- Red Daemon", which has an even more destructive effect. "Red Daemon" also got evolutions like the original "Red Daemon's", but the evolutions of "Red Daemon" are far more demonic looking with even more menacing names: "Abyss", "Bellial" and "Calamity". Those three version look outright more like demons than actual dragons despite still being labeled as such.

*** The Four Heavenly Dragon themselves count, as their are able to bring out the inner darkness (Z-ARC) that is residing within their wielders, and the four dragons had a dark history in the past. Aside from that, Odd-Eyes Pendulum Dragon, which is probably the most soft-hearted of the four, uses {{Hellfire}} as its BreathWeapon, is not hesitant to inflict physical violence on duelists, and has the most demonic evolution of the four, "Supreme King Violent Dragon - Odd-Eyes Raging Dragon". "Dark Rebellion Xyz Dragon" is black and purple dragon that brutally pierces the enemy with its pointy chin that is charged with lightning, and if combined with "Odd-Eyes", they become the very aggressive "Supreme King Black Dragon - Odd-Eyes Rebellion Dragon" that tears the enemies apart with its lightning-charged tusks. "Clear Wing Synchro Dragon" is actively looking for the other dragons to force them into fights, and "Starve Venom Fusion Dragon" is a horrific dragon with man-eater plant attributes that can swallow other monsters whole or even eat humans, and "Starve Venom's" Fusion Materials require them to be two DARK monsters. All four gain corrupted forms known as "Supreme King Servant Dragons", acting as Z-ARC's elite squad of four powerful dragons that protect "Z-ARC" while he also protects them with his mere presence alone. In order to beat "Z-ARC", the characters have to beat him alongside his Four Heavenly Dragon at once.

** In ''VideoGame/FireEmblemThreeHouses'' it turns out [[spoiler:the legendary Immaculate One dragon and the saint Seiros are the same person, and she's also Archbishop Rhea. While normally benevolent and representative of DragonsAreDivine, on the one route where the player can side against her she undergoes SanitySlippage and is fought in dragon form after setting fire to a city at night. On another route, she is also fought in dragon form, this time after a rapid succession of traumas forcibly transforms her and she begins to go mad, though as this boss battle is portrayed as a tragedy, any demonic framing is significantly downplayed in favor of underscoring that this is a MercyKill]].

** In ''VideoGame/FireEmblemThreeHouses'' it turns out [[spoiler:the legendary Immaculate One dragon and the saint Seiros are the same person, and she's also Archbishop Rhea, who has been feeding Fodland with false history for over a millennia. Depending on the route, she is fought after her FaceMonsterTurn]].

*** "Red-Eyes Black Dragon" is a mild case of this, being an entirely black-scaled dragon with [[RedEyesTakeWarnining red eyes]], and being first introduced by the minor antagonist Dinosaur Ryuzaki (his Serpent Night Dragon also fits this trope). However, Ryuzaki loses "Red-Eyes" to Jonouchi, which would continue to act as a heroic dragon for the rest of the series while displaying less demonic traits in ''Duel Monsters''. Its BreathWeapon "Kokuendan" translates to "[[{{Hellfire }}Black Fire Bullet]]".

** Dragons like the [[https://tagger.scryfall.com/card/lgn/104 Kilnmouth,]] [[https://tagger.scryfall.com/card/lgn/104 Avaricious]], and [[https://tagger.scryfall.com/card/isd/129 Balefire]] Dragons come in threatening big red motifs. [[https://scryfall.com/card/dtk/218/dragonlord-kolaghan Some dragonlords]] combine this and [[FeatheredFiend feathers, fitting a "dark angel" mindset and the fact they're tyrannical jackasses lording over certain realms]]

*** The Duel Dragons in general act as more darker versions of several of the Signer Dragons, but they also have even more members. "Demon King Dragon -- Beelze", "Underworld Dragon -- Dragonecro" and "Purgatory Dragon -- Ogre Dragoon" are especially blatant examples of this trope due to their very demonic designs, which even look more horrifying after "Beelze" and "Dragonecro" evolve.

** ''Manga/YuGiOh'' (manga & anime): The Fusion of Jonouchi's "Red-Eyes Black Dragon" and Yugi's "Daemon's Summon" is called "Black Daemon's Dragon", and it also has the moniker "Devil Dragon". This moniker would later be added to "Black Daemon's Dragon's" name with its retrained version in the OCG, making it "Devil Dragon -- Black Daemon's Dragon", which is pretty much what the original version was called in the manga/anime anyway.

** ''Anime/YuGiOhGX'' (anime): Duel Monster Spirit Yubel is a demon (and even classified as such in the OCG) but was also described as draconic in [[AmbiguousGender their]] past life. This is far more obvious in their [[OneWingedAngel "Terror Incarnate" and "Ultimate Nightmare"]] forms.

** The Evil Dragons (called Shadow Dragons in the English dub, or Devil Dragons in the German dub) from ''Anime/DragonBallGT'', spawned by the Dragon of the Black Smoke, an EvilCounterpart of Shenlong, are evil beings created by the overuse and built-up negative energies of the Dragon Balls through the series, and serve as the final antagonists for our heroes to defeat. Fittingly enough, a good deal of them look quite similar to traditional depictions of winged, horned demons and they all exist to create as much chaos and destruction as possible. However, Sixinglong is instead a TokenGoodTeammate who eventually teams up with Goku to try and defeat Super Yixinglong. [[spoiler:Alas, he is defeated]].

** Myth/SaintGeorge The dragon defeated by Myth/SaintGeorge, which was terrorizing towns eating people and livestock. George claims to have defeated the creature through the power of Christ, which implies the dragon is literally of demonic origin. As noted above, dragones being demonic was once a common Christian belief. In some stories saints simply command them to leave in the name of Christ, and they do (essentially, exorcism), although that's less dramatic.
