One of the most powerful beings in the universe, dragons are created from large masses of energy. They are divided into several different classes and are also fond of hoarding treasure. In some cases, the dragons are sealed in Sacred Gears until the user releases them. Many Dragons have been sealed or killed for being too dangerous.

    In General 
  • The Ageless: All other races age, including Gods. Dragons are immortal unless they're killed. Specifically they stop aging once they reach maturity.
  • Breath Weapon: As expected, many can breath fire.
  • Chaotic Neutral: Invoked. According to Ddraig, in the past, most dragons just lived freely to their hearts content. These days, it depends on the dragon. The dragon race as a whole ignored the Great War between the Three Factions (though select individuals did pick a side.
  • Death Is Cheap: It's very hard to kill off a Dragon for good, as their souls can persist well past their bodily destruction.
  • Dragons Are Divine: Ophis and Great Red are considered Dragon Gods, and the strongest beings in the setting.
  • Dragon Hoard: Some of them are known to collect treasure. Fafnir requires his contractor to give him something for his help (which, in Asia's case, is often lingerie), and Tiamat's briefly mentioned hatred of Ddraig is later revealed to be the result of Ddraig losing some treasure that he borrowed from her to fight Albion.
  • Kryptonite Factor: The only things that can kill dragons are dragon-slaying weapons like Issei's Ascalon or the blood and attacks of the fallen angel Samael.
  • Our Dragons Are Different: The most powerful race in the story are dragons themselves. Both Western and Eastern dragons appear, but the majority who are relevant to the story are Western.
  • Too Powerful to Live: Many Dragons, particularly the Evil ones, were killed off or sealed to stop their rampages.
  • Super Toughness: Their scales can be very hard to damage without a Dragon Slayer.
  • Unstoppable Rage: With enough provocation, a Dragon will enter "Outrage" mode, becoming significantly more powerful and vicious. Azazel commented that most people know better than to piss one off.


Heavenly Dragons

Dragons based from the Arthurian legend of Merlin watching an endless colossal fight between a red and white dragon (who symbolises Wales and England, respectively).
    Tropes applying to both 
  • Back from the Dead: Issei's consumption of Amrita allows Ddraig to temporarily manifest after 8 minutes have passed in his Diabolos Dragon form. Later, Vali learns to manifest Albion.
  • Forever War: Ddraig and Albion have basically forgotten what the fight was originally about. Volume 21 implies it was Ddraig's flames and Albion's poison being ineffective on each other that started it, as it gave them each a Worthy Opponent for the first time in their lives, convincing them to both get stronger by constantly challenging and fighting each other.
  • Inelegant Blubbering: Ddraig and Albion are completely humiliated by the former's perverted host earning the title "Breast Dragon Emperor", and are prone to uncontrollable sobbing when the topic is brought up. It didn't help when Odin labelled Albion "Butt Dragon Emperor" because Vali half-heartedly said that women's hiplines look nice when pressed for his fetish.
  • Laser-Guided Amnesia: The Biblical God sealed off their memories of any abilities they had other than Boost and Divide. Once they put aside their animosity for good (which is implied to have been God's intent) over their shared struggles with breasts and butts, they begin recovering their previous abilities.
  • Sealed Evil in a Can: Their intrusion in the Great War provoked the Three Factions forming an Enemy Mine, ending with their bodies getting cut up and their souls sealed into Sacred Gears. Transitioned into Sealed Good in a Can as they calmed down over the years and now look back in shame at their earlier rampages.

    Welsh Dragon Y Ddraig Goch
Voiced by: Fumihiko Tachiki (Japanese) and Christopher Sabat (English)


One of the two Heavenly Dragons who got sealed thanks to them fighting off the other three factions. He is the dragon who is residing with Issei as the Longinus "Boosted Gear", and thus he has to put up with all of Issei's perverted antics.

  • Armor-Piercing Attack: His long-forgotten Penetrate ability allow his attacks to ignore his opponent's defensive abilities.
  • Bilingual Bonus: Ddraig is part of a Welsh phrase meaning "The Red Dragon".
  • But Now I Must Go: Subverted. He tells Issei that he's losing consciousness because of him using up his powers in trying to maintain Issei's soul while Great Red and Ophis are creating his new body. Issei then sheds a lot of tears until he hears Ddraig snoring.
  • Cassandra Truth: He did hear the voice of the Breast Fairy when Issei accidentally summoned it instead of being able to talk to Akeno's breasts with Bilingual. Everyone just thinks Ddraig lost it.
  • Cosmic Plaything: Ddraig doesn't appreciate it when he gets called Oppai Dragon by both Ophis and Great Red.
  • Cry Cute: This trope is usually Played for Laughs regarding his humiliation over current host's obsession with breasts and the resulting title of "Breast Dragon Emperor". Played for Drama when Issei dies, and Ophis sounds somewhat surprised to hear him crying.
  • Embarrassing Nickname: He doesn't like being called Oppai Dragon (Breast Dragon) and the Breast Dragon Emperor.
  • Hour of Power: In Volume 25, Issei drinks Amrita to extend his Pseudo DxD form to 88 minutes, which also allows Ddraig to temporarily materialize and fight together with his partner.
  • Intergenerational Friendship: Considers Issei to be a true friend seeing as his former hosts never really talked much with him.
  • Large Ham: Not fully, but he does put a lot of energy into his battle phrases, such as 'Boost!'
  • Lonely at the Top: He was this until he met Albion. If he had never met him, he would have been only famous for his god consuming flames and wouldn't have developed his Boost and Penetrate abilities.
  • Meaningful Name: Ddraig is part of the Welsh phrase Y Ddraig Goch, meaning "The Red Dragon". It also appears on the flag of Wales.
  • Mood Dissonance: He tells Issei that it was fun being with him and it actually looks like he's about to say his last words to his partner. Issei couldn't even control his tears at his closest partner disappearing from him until Issei hears Ddraig snoring.
  • Playing with Fire: Blazing Inferno of Scorching Flames, Ddraig's ultimate finishing move. These flames can burn anything, and once ignited, will not extinguish until ash is all that remains. Even Gods will be burnt to ashes within the flames. It is only ineffective against Albion, Ophis and Great Red, while Trihexa can get around it by regenerating faster than the flames can burn it.
  • Pre Ass Kicking One Liner: In the dub, Ddraig's warning to Shalba becomes this:
    Ddraig: You made a poor decision, and now you must pay!
  • Red Baron: Known as the Welsh Dragon and the Red Dragon Emperor.
  • The Rival: Him and Albion have been going at it for centuries.
  • Sleep-Mode Size: Suffers a bizarre variant in Volume 14. The strain put on him to help resurrect Issei after his second death as well as the constant humiliation associated with breasts led to Ddraig mentally reverting a child (he doesn't have a body to physically revert).
  • Status Buff: His Boost ability allows him to repeatedly double his power.
  • Tempting Fate: When Issei reachs Balance Breaker with poking Rias' breast, he exasperatedly comments that he is going to cry if Issei keeps powering up this way. Guess what happened?
  • Undying Loyalty: When Euclid Lucifuge offered him a more powerful host by joining him, Ddraig quickly rejected his offer, saying that he wants to remain with Issei despite gaining the Oppai Dragon nickname and being the weakest of his past hosts, because he's a better host than all the others.
  • Vitriolic Best Buds: He hates his partner's obsession with breasts, but otherwise enjoys his time with Issei because no other host has talked to him as much, generally just focusing on power.

    Vanishing Dragon Albion Gwiber
Voiced by: Ryota Takeuchi (Japanese) and Mark Fickert (English)


One of the two Heavenly Dragons who got sealed thanks to them fighting off the other three factions. He is the dragon who is residing with Vali in the form of the Longinus "Divine Dividing".

  • Attack Reflector: His long-forgotten Reflect ability allows him to repel enemy attacks as well as his own to redirect them. Ironically, it's Ddraig's host Issei who first makes use of this power via Dividing Gear.
  • Cry Cute: He's quite upset that his rival has become associated with breasts, and Odin attempting to associate him with butts after Vali's half-hearted admission to liking hips didn't help his ego in the slightest.
  • Embarrassing Nickname: Odin calls him the Butt Dragon Emperor after Vali reveals his fetish for women's butts in Volume 7.
  • In-Series Nickname: Ddraig calls him the "White guy".
  • Lonely at the Top: Was this until he met Ddraig. If he had never met him, he would have been only famous for his poison and wouldn't have developed his Divide and Reflect abilities.
  • Mana Drain: His Divide ability steals half the power from an opponent he's touched.
  • Meaningful Name: His name is the ancient Greek name for Great Britain. The word was used also by some Romans (instead of the official Britannia) and so it's sometimes confused as a derivation of "albus", that means "white". Also, "Gwiber" means "Serpent" in Welsh, denoting his serpent-like original form.
  • Not So Stoic: His heart disease, as how they put it, get's so bad that Albion gets hysterical and hyperventilates at the mere mention of breast.
  • Our Wyverns Are Different: In volume 21, it's revealed that Albion was once a poisonous dragon named Gwiber (a Welsh word cognate with "wyvern"), but became disgusted by his abilities and sealed them away. When he comes to accept his old name he unlocks a version of Dividing Wyvern Fairy for Vali, equipped with a poison which can kill even Gods.
  • Poisonous Person: Long ago, he was feared for his venom, which could reduce any organic matter inlcuding Gods. It was only ineffective on Great Red and the infinite Ophis, as well his eventual rival Ddraig, which motivated him to stop using it and train his body.
  • Power Gives You Wings: This is what his Sacred Gear form, Divine Dividing, looks like. When Vali and Albion activate the spell, his armor sprouts several wings.
  • Red Baron: He is known as the Vanishing Dragon and the White Dragon Emperor.
  • The Rival: Him and Ddraig have been going at it for centuries, to the point where the two have basically forgotten what the fight was originally about.
  • The Stoic: As Ddraig's opposite, his tone generally doesn't change all that much, no matter what ('Divide!' included) - even his This Cannot Be! reaction to Issei incorporating his power in addition to Ddraig's wasn't too different.


Dragon Kings

    Blaze Meteor Dragon Tannin

Voiced by: Tarou Yamaguchi (Japanese) and Matt Thurston (English)

One of the former Dragon Kings from Middle-Eastern/Jewish mythology. He turned himself into a devil to get a piece of land in the underworld for his fellow dragon-kind to live in. He's also one of Issei's mentors in fighting. One of the few reborn devils to reach Ultimate Class, he is Issei's inspiration. Has been Top 10 in the Rating Game for decades.

  • Authority Equals Asskicking: He's capable of kicking ass and is one of the Dragon Kings.
  • Badass Teacher: The Occult Club couldn't even't dent him while he used less than a thousandth of his power, and he later runs Issei through a harsh training regimen that allows him to activate his Sacred Gear at will.
  • Chess Motifs: Since he participates in the Rating Games, of course he'd be assigned to one. It is revealed in Volume 14 that he is Mephisto Pheles' Queen.
  • Fun Size: Can shrink himself down to Rassei's size whenever the situation calls for it.
  • Informed Ability: His dragon breath is equivalent to a comet crashing down on Earth. It's also used as a measuring stick for the Villain of the Week.
  • Jaw Drop: He makes an epic one when Issei asks him as to what mythology is the Breast God from.
  • Mentor Archetype: Azazel asks him to personally train Issei.
  • Number Two: He serves as Mephisto Pheles' Queen.
  • Opt Out: He leaves the Dragon Kings to become one of the Devils to get a piece of land in the underworld for his dragon-kind to live in.
  • Purple Is Powerful: He's depicted as purple in the anime, and his Dragon Gate color is purple.
  • Red Baron: He is known as the Blaze Meteor Dragon.
  • Screw This, I'm Outta Here!: He ditches the Dragon Kings to side with the Devils.
  • Sink Or Swin Mentor: To train Issei to properly obtain Balance Breaker, he forces him to live in the wilderness of Ria's territory while constantly trying to burn him alive (though he was somewhat holding back).

    Prison Dragon Vritra

Voiced by: Toshiki Iwasawa (Japanese) and Ray Hurd (English)

The evil black dragon from the Asura faction of Hindu mythology who, after being vanquished by Indra, had his soul split into pieces. One of them is Saji's Sacred Gear.

  • Bystander Syndrome: If it doesn't involve him, he doesn't usually bother to get involved.
  • Dark Is Not Evil: He is revealed to be an Evil Dragon, who are generally known for being Ax-Crazy, yet Vritra is on the heroes' side.
  • Mana Drain: He can suck out power from his enemies, somewhat like Albion.
  • Technicolor Fire: He is famous for his black flames, which are extremely difficult to dispel and inflict curses on whoever they burn.
  • Red Baron: He's known as the "Prison Dragon".
  • Weak, but Skilled: He is considered as the weakest of the five Dragon Kings, but has a wide array of skills to make up for it.

    Chaos Karma Dragon Tiamat 

A dragon based from the primordial water goddess of Babylonian mythology. The strongest of the Dragon Kings as well as the only female among them. According to Ddraig, she hates him. She's friends with Ajuka Beelzebub and became a referee for his Rating Games.

  • Color Motif: Tiamat is a blue-scaled dragon with a blue magic circle and a blue-haired human form who wears blue clothing.
  • Red Baron: Chaos Karma Dragon.
  • The Smurfette Principle: The only female Dragon King.
  • Weredragon: She can transform into a beautiful woman with blue hair at will (which is consistent with the original myths where Tiamat is mostly described as a woman).
  • You Can Run, but You Can't Hide: She has been chasing after Ddraig for a long time to reclaim her stolen treasure.
  • You Gotta Have Blue Hair: In her human form, which corresponds to her dragon form's blue scales.

    Gigantis Dragon Fafnir

A dragon from the Siegfried saga of Norse Mythology and one of the five Dragon Kings in the story, he's sealed inside Azazel's artificial Sacred Gear, Down Fall Dragon Spear.

  • Authority Equals Asskicking: He's one of the Dragon Kings and can still hold his own against Rizevim.
  • Batman Gambit: Despite getting beaten up by Rizevim, he still managed to curse the guy enough that he would be tormented by nightmares. This manages to make Rizevim impatient thanks to lack of sleep.
  • Beware the Silly Ones: He was given to Asia to protect her from enemies trying to Shoot the Medic First, but each of his appearances simply serves to humiliate her by demanding her lingerie... until Rizevim hits Asia, whereupon he enters an Unstoppable Rage that doesn't end until he delivers the fatal blow on Rizevim. When he fought against Crom Cruach alongside Aisa he managed to break one of Crom Cruach's arms before being defeated.
  • Big Damn Heroes: He lands the finishing blow on Rizevim at the end of the latter's battle in volume 20.
  • Dirty Old Man: Considering the other dragons aren't even perverted in nature, he stands out.
  • The Ghost: He makes his actual appearance in Volume 14.
  • Gold-Colored Superiority: He's gold colored and is one of the Dragon Kings.
  • Kick the Son of a Bitch: He's responsible for the death of a ruthless devil who planned to revive Trihexa.
  • Power at a Price: To even have a pact with him, he just wants a treasure. Azazel had it easy because Fafnir just wanted a rare treasure. For Asia though, it's her treasured underwear.
  • Red Baron: Gigantis Dragon and Golden Dragon Monarch.
  • Unwitting Instigator of Doom: His killing of Rizevim ends up causing Trihexa to be unsealed.

    Sleeping Dragon Midgardsormr

Also known as Jormungand. One of the five Dragon Kings, he's a son of Loki and is currently sleeping at the ocean near Scandinavia. He's also the laziest dragon.

    Mischievous Dragon Yu-Long
Voiced by: Yuki Arai (Japanese)

The youngest of the five Dragon Kings in the story, he also accompanies the original Sun Wukong whenever the latter gets sent by Indra to somewhere. Also featured in Journey to the West.

Dragon God and True Dragon

    Ouroboros Dragon Ophis
Voiced by: Suzuko Mimori (Japanese) and Megan Shipman (English)
I, went under for thirty minutes.

The strongest dragon of the dragon race and one of the most powerful characters in the story. He/she/it first appeared as an old man, and then changed its appearance to a young girl. Ophis' wish is to go to the dimension where Great Red resides and kick him out of there. One of the Top 10 Strongest Beings in the World.

  • Absolute Cleavage: Her dress exposes so much of her chest that even her nipples would be completely exposed if they weren't instead covered by tape.
  • All-Powerful Bystander: Even after losing a portion of her power and becoming finite, she's still twice as strong as the Two Heavenly Dragons in their primes, but remains hidden in Issei's house because the world at large still views her as a terrorist leader.
  • Animal Eyes: Her eyes have reptilian, slitted pupils.
  • Authority Equals Asskicking: She's the initial leader of the Khaos Brigade, the strongest dragon of the dragon race and is one of the most powerful characters in the series.
  • Batman Gambit: When Samael drained her powers, she actually sent out snakes that contained her power, which helped her avoid losing 75% of her powers.
  • Because You Were Nice to Me: Ophis initially cared about nothing except removing Great Red from the Dimensional Gap. This changes when the Occult Research Club get over her being a terrorist leader. She once protected Asia and Irina from an attack simply because the former served her tea and the latter played cards with her. After being rescued from Shalba by Issei, who suffers a lethal dose of Samael's poison in the process, she helps create a new body for him and starts living at his house. Back when she led the Khaos Brigade, Vali was the only person who regularly tried to socialize with her, for which she expresses gratitude while helping create his own version of Diabolos Dragon to defeat Azi Dahaka.
  • Breast Expansion: Her breasts expand in her older form.
  • Brutal Honesty: She uses this to describe the Occult Research Club to a staff of the department store so she can page them throughout the entire store.
  • Cheerful Child: Thanks to Issei's exceptionally good parental skills, not to mention the efforts of Akeno and Rias (both of whom she recognizes as "momma"), she begins acting like a very happy and healthy little girl, to the delight of the whole harem and Issei's own parents.
  • Cherry Tapping: When Issei wakes up in his spirit form, he sees Ophis tapping the ground. When asked, all she said was "I'm defeating Great Red here." Yes, it's a mix of funny and adorable.
  • The Comically Serious: "Did you want to become the Oppai Dragon instead of the Heavenly Dragon Ddraig?" which sends Ddraig into his Heroic BSoD.
    • Hell, anytime she's on-screen, it will be a mix of both hilarious and adorable.
  • Did We Just Have Tea with Cthulhu?: Hangs out at Issei's place in Volume 11.
  • Draconic Humanoid: She's pretty much a Dragon In Name Only. Her Animal Eyes and Pointy Ears are her only telltale signs, and her Voluntary Shapeshifting seems to be limited to humanoid bodies without any draconic true form.
  • Elegant Gothic Lolita: Its current form since according to Azazel, last time Ophis appeared was in the form of an old man.
  • Foreshadowing: The dream Issei had when Ddraig made his first appearance was his marriage to Rias with his mother crying out "make sure your first child is a girl!" Ophis is currently taking on the form of a little girl, and she's the daughter of Issei and Rias (and Akeno since Ophis calls her and Rias momma), by adoption, with Issei having no prior children.
  • Happily Adopted: For all intents and purposes. She quite often acts as Issei's child, and actively calls him "Papa." She also recognizes both Rias and Akeno as "Momma" to both of their delight.
  • Has Two Mommies: She calls both Rias and Akeno "Momma."
  • Immortal Immaturity: Probably because she didn't have friends for thousands of years.
  • Intergenerational Friendship: With Issei.
  • The Load: Volume 11 is pretty much her not being able to do anything at all and is a burden to the entire group. This is actually justified, as losing some of her power made her remaining abilities unstable. When she attacked the Grim Reapers, she accidentally blew up Azazel. Also, she is effectively invincible, so she doesn't really understand the necessity of self-defense.
  • Magic Enhancement: Ophis can create snakes which massively boost the power of those who consume them.
  • Moment Killer: Dammit Ophis! Just when Issei and Ravel were having a good time at the bath.
  • Mystical Waif: The leader of a terrorist organization and one of the strongest characters in the series currently appears as a little girl, though Azazel notes that she used to take the form of an old man.
  • Nerf: Somewhat over 1/4 of her power is drained from her, lowering her from being the strongest known being alongside Great Red to being "only" twice as strong as Ddraig and Albion combined at their primes (and this while her powers were still unstable).
  • Nigh-Invulnerable: Pre-Nerf, virtually nothing works on her. She gets stabbed by Cao Cao using True Longinus, and she doesn't even flinch as the entry wound simply closes without losing a drop of blood. However, even she isn't immune to Samuel's curse, which causes the aforementioned nerf.
  • No Biological Sex: Despite choosing to appear as female, Ophis is genderless, as revealed in her side story. When the Club asks for her gender to determine which clothes to buy her, she responds "I don't know".
  • No-Sell: Does this to Cao Cao and the freaking True Longinus.
  • Older Alter Ego: She gains an older form in Volume 21.
  • Only Known by Their Nickname: Ophis is known by "Phis" to those outside the Hyoudou Household to avoid people realizing who she is and since Lilith is believed to be Ophis prior to her Heel–Face Turn. This is seen best with Kunou who even after moving into the Hyoudou Household, still doesn't know her real identity.
  • Ouroboros: Represents infinity, and her powers are manifested in the form of snakes.
  • Pointed Ears: Her current form has ears with pointed tips.
  • Puppet King: S/he is considered as the overall leader of Khaos Brigade, but the ones below her are the ones who are truly running the group.
    I just sat in a chair. I spoke my wishes. I gave snakes. That is all.
  • Quizzical Tilt: She has a habit of doing this whenever she's thinking about something.
  • Rapunzel Hair: Its current form has long black hair down to her hips.
  • Red Baron: The Infinite One and the Infinite Dragon God.
  • Redemption Demotion: As soon as she finally joined Issei's group, almost all of her power was drained (most of it swallowed by Samael, and then had to create Issei's body alongside Great Red).
  • The Rival: To Great Red.
  • Steven Ulysses Perhero: Ophis is the Greek word for "Snake", referring to her abilities.
  • The Stoic: Rarely shows any sort of emotion.
  • Story-Breaker Power: Even if she got hit with the Nerf stick, she's still twice as strong as Prime!Ddraig and Prime!Albion combined, which is why she's not out fighting alongside the members of the Occult Research Club.
  • Super Empowering: She gives both Issei and Vali the Diabolos Dragon armor, which allows them to defeat opponents as strong as their own Heavenly Dragons, but not without severe backlash.
  • Sweet Tooth: Ophis loves eating sweets. This trait was also passed down to Lilith her clone.
  • Terse Talker: Her way of talking is extremely sparse and laconic.
  • Trademark Favorite Food: She often snacks on bananas while living in Issei's house.
  • Voluntary Shapeshifting: S/he's capable of shifting from one form to another. As noted by Azazel, form for Ophis is just a decoration.
  • The Worf Effect: Her {Nerf} courtesy of Samael proves that the latter's reputation as the ultimate Dragon Slayer isn't just for show.
  • Worf Had the Flu: She is beaten to a pulp by one of the Evil Dragons of Qlippoth. Aside from her getting nerfed, this happens because said dragon was using Issei's parents as shields, and kept threatening the dragon egg she was tasked with guarding so she could not run away.
  • World's Strongest Man: Pre-Nerf she was this taking the top spot of the Top 10 Strongest Beings in the World.

    Apocalypse Dragon Great Red

The only one who can rival Ophis and is currently residing in the Dimensional Gap. Ophis' wish is to kick him out of there while Vali wishes he could fight him. He also represents dreams.

  • All-Powerful Bystander: Is the single strongest known being in existence alongside Pre-Nerf Ophis, but just swims in the dimensional gap without bothering anyone, and the various gods, demons, and other factions likewise leave it alone. Word of God excludes him from the Top 10 Strongest Beings in the World for this reason.
  • A Taste of Power: From Issei's perspective. Issei was shocked in awe as to how powerful Great Red really is.
  • Delinquent: How Issei describes him as: a biker gang dude who hates being stared at.
  • Disproportionate Retribution: When a monster glared at him, he tells Ddraig that he'll combine with him and wipe out all the huge monsters.
  • Dynamic Entry: How he enters the underworld with Issei and Ophis at his back. While inadvertently, to the tune of the Gropin' Dragon. The guy knows how to make an entrance.
  • Fusion Dance: With Issei after the latter's revival, turning him into a giant to defeat Jabberwocky.
  • Kaiju: Great Red is positively colossal.
  • Killed Off for Real: He was killed by Melvazoa's older brother Regalzeva in True Volume 4.
  • Red Baron: He's known as the True Dragon, The True Red Dragon God Emperor, and "D x D" (Dragon of Dragons).
  • Satan: Averted in-story, but he represents the Great Red Dragon that Satan became in the Book of Revelation.
  • Story-Breaker Power: It's a good thing he doesn't fight actively and chills around at the Dimensional Gap, otherwise the whole story would have been over.
  • Suddenly Voiced: While Issei is getting his body reconstructed with Great Red's flesh, anything he wants to say is conveyed by Ddraig. After helping Issei destroy the Jabberwocky and save the Underworld, what are the first words that come directly from his mouth? The Oppai Dragon song!
  • The Rival: To Ophis.
  • Title Drop: It's known as "D x D" or Dragon of Dragons.
  • The Worf Effect: He is easily defeated by Regalzeva to establish just how dangerous the invaders from Ex E will be.

Evil Dragons

    In general 
  • Ax-Crazy: They were feared for wanting to destroy everything, including themselves. Even Ddraig and Albion decided against confronting them, despite being much more powerful than the strongest three in the past. Grendel and Azi Dahaka fought against each other just to figure out who's going up against the Vali team.
  • Back from the Dead: With the exception of Crom Cruach, who never died in the first place, and possibly Níðhöggr (Rossweisse explicitly notes that they're not sure if he revived on his own or not), they were all revived by the Sephiroth Graal, with their vulnerability to Dragon Slayers slightly mitigated, to serve Qlippoth.
  • Dark Is Evil: All of them except Ladon are described as having black scales.
  • Resurrective Immortality: Volume 21 implies that as long as even a small piece of an Evil Dragon's soul remains, they can revive themselves, though it takes a few thousand years. Azi Dahaka and Apophis both hope to have a rematch with Vali and Issei, respectively.

    Crescent Circle Dragon: Crom Cruach
Dark Dragon of the Crescent Moon

The strongest known Evil Dragon that is based on an old god in Irish Mythology. He makes his first appearance in Volume 16 in a human disguise but is forced to partially reveal his dragon form in a battle against Issei and Vali.

  • Aloof Ally: He joins Rias' team in the Azazel Cup, though he's just looking for a good fight (and bananas), and he's not that close to them.
  • Badass Normal: By Dragon standards, anyway. By the Azazel Cup, he's noted to have become even stronger than Ddraig and Albion in their prime, while lacking any special abilities like their Boost and Divide. He can only throw his weight around and shoot aura or fire breath like most other Dragons.
  • Big Damn Heroes: In Volume 20, he rescues Issei's parents from Níðhǫggr and kills him.
  • Break the Badass: This guy can make Grendel back down from a fight.
  • Comically Missing the Point: He seriously has no idea why Fafnir would want Asia's school swimsuit. He even thought that Fafnir was going to swim.
  • Even Evil Has Standards: He is disgusted by most of Qlippoth's actions, but what really tips the scales is how one of his fellow evil dragons tormented Ophis. He breaks out his true form on the culprit, Níðhǫggr, and contniuously beats him down, presumably force-feeding him his horde of synthetic Phoenix Tears until they run out, just to prolong the suffering, and use up the supply so Qlippoth won't have access to them.
  • Heel–Face Turn: He ends his partnership with the Khaos Brigade after the battle against Heaven in Volume 18.
  • Last of His Kind: As of the end of volume 21, Crom Cruach seems to the the only evil dragon left.
  • Mark of the Supernatural: In his human form he has a mixture of black and blonde hair with matching black and gold eyes.
  • Meaningful Name: His title is actually the meaning of his name, and in the original myths he is suggested to be a solar deity.
  • Noble Demon: While he does enjoy fighting strong opponents, he has much more self-control than the other Evil Dragons.
  • Paper-Thin Disguise: His cover as "Mr. Black", a temporary replacement Pawn within Rias' team. It is just him taking his human form with a different set of clothing (black, in this case).
  • Red Baron: Crescent Circle Dragon, Darkness Dragon and Dark Dragon of the Crescent Moon.
  • Rule of Three: With Ddraig and Albion, Crom Cruach is the third dragon from the British Isles, and they are considered the strongest of their kind (excluding Ophis and Great Red)
  • Scaled Up: He turns into his true gigantic dragon form during his battle with Níðhǫggr.
  • Sole Survivor: Barring the mass-produced Evil Dragons that decided to serve Asia, he is the only Evil Dragon who's alive and well by the end of the fourth arc; the rest were sealed or simply killed (though they're implied to have Resurrective Immortality).
  • Super Toughness: He can tank Issei's Ascalon boosted Crimson Blaster attack with only minimal damage. What makes this so remarkable is that unlike Grendel he has never been modified to be immune to Dragon Slayers.
  • Took a Level in Badass: He's stated to have been training his body and mind in both the Human World and the Underworld for the time that Ddraig and Albion have been sealed. When Ddraig finally meets him again he states that he may have even attained strength to that of the Heavenly Dragons. By the final arc, he's surpassed them.
  • Trademark Favorite Food: He gets hooked on bananas after Asia gave him one. A constant supply is one of his requirements for serving Rias in the Azazel Cup.
  • Weredragon: He has the ability to shapeshift from his dragon form to his human form at will, which he finds more convenient, and claims that his human form doesn't noticeably reduce his power compared to his dragon form. He then reveals his true dragon form in Volume 20 before a frightened Níðhǫggr.
  • Weaksauce Weakness: Subverted. He originally could be critically injured by using Tathlum, the magical bullets that killed Balor, but his training makes him capable of defending against it.

  • Combat Sadomasochist: Akeno's got nothing on him. The protagonists are particularly disturbed when getting his eye gouged out, and then most of his body getting vaporized, only excites him further.

The jewel with Grendel's soul was then given to Heaven to safeguard behind a multitude of defensive barriers.
  • Super Toughness: Even for a Dragon he's known to be able to tank insane amounts of damage, so much so that Rossweisse suspects that his defense has been further enhanced since his resurrection. He's been shown shrug off attacks from Xenovia's Ex-Durandal, an Ascalon boosted CCD Issei, and even Kiba's Demonic Emperor Gram.
  • Too Kinky to Torture: He loves pain.

  • Red Baron: Insomniac Dragon.
  • Sealed Evil in a Can: In Volume 18, Ladon is the second Evil Dragon to be defeated through the sealing method that captured Grendel.

  • Dirty Coward: He delivers a truly horrific No-Holds-Barred Beatdown on Ophis. How? He uses Issei's parents as human shields so Ophis can't fight back, and keeps threatening the egg so Ophis can't run away. The moment he sees Crom Crauch, who's also guarding the egg appear, he quickly flies away.
  • Hate Sink: He kidnaps Issei's parents, uses them as hostages to beat the crap out of Ophis, and then fantasizes about how good the former couple will taste in front of their son while fondly reminiscing over his beatdown on the latter. His actions are so abhorrent and cowardly that fellow Evil Dragon Crom Cruach turns on him.
  • Power Of Hate: The legend is that he's so full of hate and resentment that he would even resurrect himself after Ragnarok, which is supposedly the end of all things.
  • Red Baron: Abyss Rage Dragon and Extrajudicial Death Dragon.
  • Resurrective Immortality: It's not clear whether he's alive to serve Qlippoth because of the Holy Grail or just his natural ability to revive himself with his undying malice.

  • The Archmage: Said to have control over a thousand magics. It's not clear whether that means a thousand different spells or a thousand different styles of magic, but his power is appropriately feared by the Gremory and Sitri groups.

  • Came Back Strong: Invoked. Every time he's defeated and resurrects he grows stronger.
  • Expy: Word of God attributes his design to King Ghidorah.
  • Lightning Bruiser: Considered by Kuroka as the strongest enemy they've fought. Given they already fought a god with his wolves that can kill a god alongside the Gremory team and Tannin included, the scale just went off the charts.
  • Lotus-Eater Machine: He traps Vali in one in volume 21, giving him the experience of an ordinary loving family like Issei's. When Vali works up the willpower to leave, Azi Dahaka praises him and apologizes for resorting to such tactics.

An evil dragon from Egyptian mythology. Also known as Apep, the Light Eater and arch-enemy of Ra (or Aten).

  • Affably Evil: He has a refined and sophisticated personality and is nothing but polite during his fight with Issei. This doesn't stop him from using Trihexa to attack multiple mythologies and the human world.

  • Casting a Shadow: He uses shadow attacks that have a Touch of Death ability.

A Japanese evil dragon who was already killed by the god Susanoo.
