Dragon Physiology (High School DxD)

==Summary==
Dragons are a major species present in the High School DxD series. Dragons make up one of two of the most powerful races in the world, the other being the Gods of Mythology. Together, their very world became marked with the "Draconic Deus" by the otherworldly race from another world called the Evies.
Among many of the supernatural races to exist, Dragons are considered the mightiest of them all aside from the very Gods themselves. They are entities who are feared, respected, and admired by many, to some extent even being worshipped like Gods themselves. This is especially prominent for many, ranging from the Evil Dragons to the Heavenly Dragons and, most of all, the very Dragon Gods themselves who stand at the peak among Dragons and notably strong to even the mightiest of the Gods.
==General Abilities==
The following are abilities that Dragons of all types are capable or should be capable of having:
* Superhuman Physical Characteristics: Dragons are strong and powerful beings among many of the supernatural races, with even low-class Dragons being considered deemed for caution when confronting them.
* Longevity: Dragons are long-lived beings with lifespans exceeding that of the Gods and other supernatural racesSLASHDOG Volume 2, Origin of Calamity/Towards Infinity, easily capable of living at least thousands of years without visibly aging if not more. An example of it Midgardsormr, who had already existed for some time several hundred years prior and would continue to be around until their role in Ragnarok starts.High School DxD, Volume 7, Life 3 
* Flight (True Flight): Dragons have wings that allows them to fly and levitate.
* Transformation and Size Manipulation: Dragons have the ability to alter their appearance, ranging from simply changing their size to become bigger or smaller (ex. Tannin) to outright changing their outward appearance to that of a human as seen through Crom Cruach and Apophis. 
* Breath Attack: Dragons possess the ability to conjure a breath attack, with which can come in varying forms from dragon to dragon such as a fire breathing attack.High School DxD, Volume 5, Life 2
* Rage Power: On top of their immense power, Dragons also possess a special state known as Outrage, which causes the dragon in question to enter an enraged state that also bolsters their power and strength beyond their usual power level.High School DxD, Volume 18, Life 4 
* Summoning and Animal Manipulation: Dragons who are of a higher class can summon lower-class Dragons and even command them as though they are its servants.Junior High School DxD, Volume 1, Life 4 
==Resistances==
The following are things all Dragons are stated to be resistant to:
* Temperature Manipulation: Dragons are stated to be immune to cold and heat.High School DxD, DX 6, Extra Life
* Poison Manipulation: Issei, a wielder of the Boosted Gear which houses the Dragon Ddraig, was unaffected by a poison mist that can affect youkai and even High-Class Devils alike. Naturally, this should mean other Dragons should be immune to this poison.High School DxD, Volume 5, Life 3
* Magic: A dragon's scales are stated to be resistant towards magic.High School DxD, Volume 16, Life 3
* Elemental Manipulation: Dragons are stated to be resistant to attacks of all attributes, which are seven elemental types that consist of fire, ice, wind, earth, thunder, light and darkness,High School DxD, DX 7, Life 6 a feat demonstrated through a Chimera that was part-Dragon and thus should naturally apply to proper Dragons or have some relation to being a Dragon.High School DxD, DX 6, Life 2
==Weaknesses==
Dragon-slaying weapons and magic: Despite their might, Dragons are still susceptible to weapons and other powers such as magic that are made to slay Dragons. This applies to even Sacred Gear wielders whose Sacred Gear possess Dragons in them, in turn making them just as susceptible as shown when Issei used Ascalon, a famed Dragon-slaying weapon, to harm Vali with and even pierce through the latter's Scale Mail armor due to its draconic nature.High School DxD, Volume 4, Life 5
Dragon killing poison: Dragons are also vulnerable to powerful poisons made to harm if not outright kill dragons such as Samael's blood, the strongest poison to dragons in the series which is harmful to even the likes of the Heavenly Dragons as well as affecting the Dragon God Ophis, who was weakened to the point of going from one of the strongest entities in the world to becoming merely twice as powerful as the Heavenly Dragons at their peak. Sacred Gear Wielders wth Dragons in them are also vulnerable to this kind as shown through Issei and Vali.
Dragon-affiliated diseases and illnesses: Dragon's can suffer from an illness known as a "Dragon-Flu" which, if caught, can cause them to lose their ability to use their breath attack and other special abilities while sick. As with the previous mentioned weaknesses, Dragon-based Sacred Gear wielders can also catch and suffer the Dragon-Flu.High School DxD, Volume 13, Life 3
