Dragons (ドラゴン, Doragon) are one of the most powerful and prominent creatures in High School DxD.


Dragons are powerful supernatural beings, considered the strongest aside from the Gods themselves, admired, respected, and feared no matter the era. Among the supernatural, Dragons, as an entire race, didn't side with no one from the Three Factions during the Great War, different from Fairies, Spirits, European Monsters, Asian Monsters, and Humans.[1] However, in the end, some Dragons did end up joining the Three Factions, among the Underworld, consisting of Devils and Fallen Angels. In certain cultures and different parts of the world, Dragons are worshiped as Gods.[2]

Dragons are said to be creatures born from a large mass of power, who acts based on their desires, acting freely and selfishly, while having a high amount of intelligence. Azazel even theorized that the reason that Dragons are as so powerful, because their pure thoughts that compels them to devote themselves towards their goals, for the Evil Dragons, it would be battle and carnage, even if it meant their bodies would be annihilated too. Crom Cruach stated that Dragons are meant to live according to their will. All Dragons have pride in themselves, declaring their titles as a formal greeting or in response to accepting a challenge to a dual between Dragons or Heroes.

There have been those who were created by powerful beings, such as Midgardsormr and his clones, who were created by the Evil God, Loki. And then Aži Dahāka, Aži Dahāka II, Ddraig II, and Albion II, who were all creations of the Evil God, Angra Mainyu. Aside from that, Dragons can be mass-produced and beings can be turned into a Dragon through using powerful items such as the Longinus, Sephiroth Graal, and God of the Bible, who'd cursed Samael into a half-Fallen Angel, half-Dragon.

Dragons loves hoarding treasures as seen with both the Dragon Kings, Tiamat, and Fafnir, the former had hoards of treasures, but Ddraig borrowed some of them, and ended up losing them, then scattered all across the Human World. Losing a Dragon's treasure, no matter how small would result in them relentlessly pursuing whoever lost them, as shown when Tiamat hunted down Ddraig and his possessors or centuries, to make them pay for losing her treasures. Fafnir, has a treasure trove located in the Dragon Range, ranging from famous items, weapons, as well as Asia's lingerie, sometimes wanting something from his contractor and summoning them into battle using a summoning portal from his mouth.

No matter, it is a mistake to anger Dragons, a Low-Class Dragon, more so one of the Heavenly Dragon and the Dragon Kings. The reason being, because of their Outrage, as shown when the Dragon King, Fafnir, who wielded power equal to or greater than Rizevim Livan Lucifer, a Super Devil, then fought Crom Cruach, the strongest Evil Dragon, who surpass the Heavenly Dragons. The simplest, efficient method of calming down an enraged Dragon (or someone in possession of one via a Sacred Gear) is to sing them a specific song, as proven when the Oppai Song was used to calm down Issei, who entered Juggernaut Drive.

In the present, almost all powerful and legendary Dragons are either sealed inside of the Sacred Gears, such as Ddraig, Albion, and Vritra; dormant, missing, or dead. As shown by Ddraig, they revert back to being baby mental state, if they don't heal properly as a result of using up too much of their powers.


Dragons are creatures with reptilian traits. There are two physical types of Dragons, Western Dragons, and Eastern Dragons.

  • The Western Dragons (ウエスタン・ドラゴン, Uesutan Doragon) are a lizard-like creature that stands on four legs, leathery or bat-like wings growing from their backs, and a long, muscular tail.
  • The Eastern Dragons (イースタン・ドラゴン, Īsutan Doragon) are typically portrayed as serpentine creatures that have long, slim bodies with four legs, and without wings.

Various Dragons come in different colors, from red (Flame Dragon or Ddraig) to white (Albion) to blue (Tiamat or Sprite Dragon). Most Evil Dragons have black scales.


The Dragons are divided into many different classes. There are the normal Dragons, the Dragon Kings which are above the normal Dragons, the Heavenly Dragons which are above the Dragon Kings, and the True Dragon and Dragon God, the highest class of Dragons.

True Dragon

The True Dragon (真龍, Shinryū) is a class that solely belongs to Great Red, the Apocalypse Dragon and the True Red Dragon God Emperor who is known as the "Dragon of Dragons (D×D)". It is the title given to Great Red as the most powerful of Dragons. While Great Red is the only Dragon that belongs to this sub-class, in Volume 12, it is said that Issei could be thought of as a small True Dragon because of having his new body made from Great Red's flesh.

Dragon God

The Dragon God (龍神, Ryūjin) is a class that belongs to Ophis, the Ouroboros Dragon and founder of the Khaos Brigade, and Lilith, the spawn of Ophis. Great Red is also considered one of the Dragon Gods, in addition to being a True Dragon.

Two Heavenly Dragons

The Two Heavenly Dragons, Ddraig and Albion.

The Two Heavenly Dragons (二天龍, Nitenryū) are Dragons with powers that can kill both Gods and Satans, and are considered to be one of the highest class of Dragons. The two Heavenly Dragons are the Red Dragon Emperor, Ddraig, and the White Dragon Emperor, Albion.

In the past, the two Heavenly Dragons fought a fierce battle, which was interrupted by the Angels, Devils, and Fallen Angels who were at war during the time. In anger, both Dragons attacked the leaders of the Three Factions, which led to their bodies being destroyed and their souls being sealed into two separate Sacred Gears.

Currently, both of the Heavenly Dragons are sealed within two separate Sacred Gears: Boosted Gear and Divine Dividing.

Five Great Dragon Kings

The Five Great Dragon Kings (五大龍王, Godai Ryūō) are a group of five (previously six) unique Dragons with high destructive powers, rivaling those of Ultimate-Class Devils or even the Four Great Satans. The Five Dragon Kings are Tiamat, Yu-Long, Vritra, Midgardsormr, and Fafnir. Tannin was also one of the Dragon Kings before leaving and joining the Devils.

It is unknown how a Dragon reaches this class, as the other classes appear based on the Dragon's specific type, while the Dragon Kings are of different types and factions.

Low-level Dragons

Low-level Dragons: A Dragon class that belongs to normal Dragons. The only Dragon that has been revealed that belongs to this class is the Earth Dragon.

  • The dinosaur that appeared in the short story A Tokusatsu Devil is an example of an Earth Dragon.

Evil Dragons

Another class of Dragon that is first introduced in Volume 14.

The Evil Dragons (邪龍, Jaryū) are known to be more powerful than the Five Dragon Kings while the most powerful Evil Dragon in existence, Crom Cruach, is said to be as strong as a Heavenly Dragon. The Evil Dragons are stated to be the most vicious and brutal of all Dragons, all being dangerous battle maniacs that want to destroy everything including themselves. All Evil Dragons were considered as extinct before the beginning of the series. They are considered as "broken Dragons" and are feared by all the factions of the world due to their immense power and extremely savage brutality. Evil Dragons are considered nearly impossible to control as only Evil Gods and Malevolent Gods were able to control them in the past[3].

Evil Dragons can revive themselves naturally if a part of their soul remains. This process, however, consumes a large amount of time.

The Dragons of this class include:

Aži Dahāka Diabolism Thousand Dragon

All the currently known famous Evil Dragons were revived by Qlippoth of the Khaos Brigade for the Evil Dragon War. Out of the seven named Evil Dragons, Crom Cruach defected from Qlippoth, Aži Dahāka and Apophis betrayed Rizevim, Grendel and Ladon were both sealed after their defeat, while Yamata no Orochi, Apophis, Aži Dahāka, and Niðhöggr are the only Evil Dragons who died in battle. In Volume 16, Rizevim reveals that with the help of the Sephiroth Graal, he could mass-produce Evil Dragons, using it on the Vampires that already modified themselves using the Holy Grail. The mass-produced Evil Dragons are said to have at least the strength above a Mid-class Devil. Four of these dragons defected and formed a contract with Asia Argento after seeing Fafnir's impromptu cooking show in Volume 17.

Asia named the four:

Dragon Children

Are a group of Dragons who are children of the higher-class of Dragons. So far Tannin, the former Dragon King is known to have three sons.

Other Dragons

There are certain Dragons that don't belong to or have a proper class due to being either former Dragons or even a Dragon that doesn't have a proper classification. After being reincarnated into a Devil, Tannin has lost all rights to be called a Dragon King. Samael, who appears to be a between between a Fallen Angel and Dragon, but can't be considered as either. Issei Hyoudou was turned into a Humanoid Dragon, having gained a new body made up of Great Red's flesh and Ophis' power, being considered an almost miniature True Dragon, but similar to Tannin, he was reincarnated into a Devil once again.

Powers and Abilities

The abilities of a Dragon differ between classes, their specific races, and in some cases, the specific Dragon. All of them have demonstrated the power of flight and their own elemental breath (either fire, ice, or lightning). Their breath attacks, physical attacks, and aura are noted to be their most basic forms of offense. Dragons often display high durability because of their tough scales.

There have also been dragons who have developed their own abilities aside from their basic ones such as Ddraig (Power Multiplication and Transference), Albion (Power Division and Absorption), and Vritra (Power Absorption and Transference).

A frequently seen trait amongst the higher classes of Dragons is the ability to change their appearance to varying degrees. This trait ranges from changing their size (Tannin and his son Bova Tannin) to completely changing their outward appearance (Yu-Long, Crom Cruach, Ophis, Tiamat, Apophis, and Alivian).

It has been stated (and shown by Issei) that Dragons draw strong allies and enemies to them.

Unlike other races that have long lifespans measuring to a millennium, all dragons have a limitless lifespan, as a dragon doesn't age after reaching maturity and will only die if they are killed. Dragons (and by extension Dragon Sacred Gear possessors) are immune to poisonous mist created from Youjutsu, which is said to be able to work on even higher ranking Devils and Youkai.

Outrage: As stated in Volume 18, all dragons seem to have the ability to enter an empowered state of sorts when they are angered. In this state, physical abilities increase significantly. When Fafnir entered this state, his power was enough that he was able to knock Lilith to the side and bite off one of Rizevim Livan Lucifer's arms. In the Outrage state, dragons will relentlessly pursue their enemies. Ddraig and Albion also entered Outrage mode back in the Great War and lashed out at the leaders of the Three Factions for interrupting their fight.

Magic: Though not many, some Dragons have the ability and also expertise in using various types and classes of magic and spells, and often to far more potent degree than any other supernatural beings, higher classes of Dragons can use high classes of magic, and even forbidden spells. Some examples of these dragons are Aži Dahaka; who both controls and possesses one thousand magic skills, Fafnir; which he uses his skills in magic to willfully open the Dragon gate and bestowed curses, and Apophis; who use his magic to contain the Holy Grail through his own dimension.

Magic Resistance: The scales of Dragons are stated to be resistant to magic.

Curse: Though not all Dragons can use curses, there are several higher ranking and powerful dragons that can create and bestow curses. In particular, those who can use forbidden magics and spells, such as Fafnir who can use his spiritual presence, Vritra's shadowy black flames that can curse both mortals and supernatural beings, and Azi Dahaka's thousand skills of ancient and forbidden magic skills.

Poison: Some dragons can utilize poison, and some of them are very deadly, not only devouring and killing a being's physical body but also its soul. In particular, the only known dragons that possess this ability are Samael, Albion, and Yamata no Orochi (Though the latters venom can be cured by certain associations such as Heaven and some Magician factions).

Dragon Gate

The Dragon Gate (龍門(ドラゴン・ゲート), Doragon Gēto) is a magic circle exclusive to the Dragons. The Dragon Gate allows them to summon another Dragon. While the Dragon Gate insignia can be drawn by someone else, it will only respond when there is a Dragon nearby. It requires 3 or more powerful Dragons to use to forcibly summon another Dragon.

The Dragon Gate insignia is positioned after the Five Dragon Kings, Tannin, the Two Heavenly Dragons, and Grendel. Each of which is represented on the magic circle by a different color:

Name Color
Ddraig Red
Albion White
Tannin Purple
Tiamat Blue
Yu-Long Green
Vritra Black
Midgardsormr Grey
Fafnir Gold
Grendel Dark Green

Despite so, there appear to be other methods to use the Dragon Gate; in Volume 9, the Hero Faction intended to use a brainwashed Yasaka and the spiritual energy from Kyoto to replace the use of the Dragons to open the Dragon Gate.

Individuals who specialize in summoning magic and have made a Dragon into their Familiar can learn to use Dragon Gate magic to summon the dragon which is Familiar.


Despite dragons being considered to be masses of power, a common weakness for dragons, as well as people with Dragon-type Sacred Gears, are objects or individuals that considered Dragon Slayers (龍殺し(ドラゴン・スレイヤー), Doragon Sureiyā). Swords imbued with dragon-slaying abilities such as the Holy Sword; Ascalon and the Demonic Emperor Sword; Gram have shown the ability to easily cut and harm Dragons as Issei Hyoudou was able to use Ascalon to easily damage and destroy Vali Lucifer's Scale Mail armor during their fight, and the Demonic Sword Emperor Gram was used by the original Siegfried to kill one of the Dragon Kings; Fafnir, though Fafnir was later revived by the Norse Gods. Dragons can gain resistance to these Dragon Slayers by either using the Sephiroth Graal; or by through intense training as seen with Crom Cruach who defended against an attack from Issei's Crimson Blaster + Ascalon.

So far, the most dangerous weapon against Dragons is the deadly poison of the Dragon-Eater; Samael, which not even immensely powerful Dragon Gods such as Ophis and Great Red can remain unaffected by; this poison had destroyed Issei's body and would have affected his soul if not for the past possessors of Boosted Gear sacrificing themselves. The poison is a result of the God of the Bible's intense hatred toward snakes and dragons.

In Volume 6, it was mentioned that Dragons can be calmed down using specific songs, though Vali mentioned that there weren't songs for the Heavenly Dragons until the introduction of the Oppai Dragon Song, which was used to calm down Issei in Juggernaut Drive. The new High-Tier Longinus; Nereid Kyrie, can be used to control Dragons or drain the powers of any Dragon who hears the user's voice while active, but it can conversely be used to strengthen them.
