==Summary==
Devils are a race of beings that make up one of the Three Factions as described in the Bible alongside the Angels and Fallen Angels in the world of High School DxD. They originated from the Underworld created by the original Lucifer and the body of Lilith to create an army of Devils to overtake the World and take down God, the Angels, and Fallen Angels. A Great War occured between the factions and by the end of it, a large number of causalities occurred including the deaths of God and the original four Devil Kings. Eventually, a method was created where the Devils can replenish their numbers, eventually leading to the development of the Peerage system and Rating Games.
There are two types of Devils in the world of DxD: Pure-blooded Devils, which are Devils that have descended from the original Devil Kings like Lucifer and through Lilith. And Reincarnated Devils, beings who are turned into a Devil and serves the one who made them as their Servant.

* Aura: High-Class Devils and higher like Riser, Rias, and Grayfia can release a pressure of killing intent that can overwhelm others with unease and even make their bodies tremble.High School DxD Volume 2, Life 2 Even Low-Class Devils like Saji at the time could release a pressure that makes others feel fear.High School DxD Volume 5, Life 5 
* Summoning: Devils can summon familiars if they have a pact with them, with which they can use them for varying means like support or mundane tasks like handing out leaflets for Devil summons.High School DxD Volume 8, Life 2 Devils with Peerages can also summon their Servants whenever desired or needed. 
* Subjective Reality, Physics Manipulation, Energy Manipulation, Unholy Manipulation, and Forcefield: Devils wield Demonic Power, which is the power to control and manifest phenomena such as conjuring fire, water, and lightning.High School DxD Volume 2, Life 3 To properly wield and manifest Demonic Power, a Devil must have the power to imagine and create the phenomena they want to conjure as well as the good sense to wield them.High School DxD Volume 14, Life 3 Devils can also use Demonic Power for more simpler purposes such as creating offensive attacks (ex. in the form of energy blasts) or create defensive barriers.High School DxD Volume 3, Life 4 Demonic Power's nature is also the opposite to that of Holy Power, being something that is the demonic and dark to that of holiness and light.High School DxD Volume 5, VIP
* Soul Manipulation: Devils like Saji can, if necessary, use their very life force (aka their soul) to turn it into Demonic Power not only to increase the potency of their attacks but also to harm their target down to their very soul.High School DxD Volume 5, Life 4 Sairaorg, a High-Class Devil with next to no Demonic Power, was able to train himself to the point of using his lifeforce in the form of Touki, enabling him to strike his foes right to their very soul.High School DxD Volume 17, Life 4
* Teleportation: Devils can cast a magic crest that they can use to travel anywhere such as between the Human World and the Underworld.High School DxD Volume 2, Life 1 
* Non-Physical Interaction and Purification: Devils have taken jobs that require them to exorcise evil spirits from people as well as dealing with killing them.High School DxD, Gremory Real Estate SSHigh School DxD, Fantasia Heroine Calendar Book 2015 SS 
* Perception Manipulation: Devils passively release Demonic Power that makes only Humans who have made contracts with them can perceive them. Anyone else not involved with their activities are unable to hear them. 
==Resistances==
* Minor Resistance to Heat Manipulation: It is stated that Devils are incapable of getting sunburned.High School DxD Volume 4, Life 1 
* Perception Manipulation and Illusion Creation: Those with special powers such as magic wielders and Sacred Gear wielders are capable of bypassing area's laced with an effect that causes ordinary beings to be driven away from said area in question, which should make Devils also capable of doing the same.High School DxD, DX 5, Life 6 Devils can also see through illusions that ordinary people aren't able to perceive.Is the Order a Devil SS 
* Curse Manipulation: People who are reincarnated as Devils cannot be cursed by evil spirits, thus also implying that Natural-born Devils also can't be cursed.High School DxD, DX 3, Life 2
* Possession: With sheer will, a Devil could resist having their body possessed and keep it up so long as their will doesn't waver.High School DxD, DX 6, Life 4 
* Mind Manipulation: A Devil's Demonic Power could be used to resist spells that affect the mind, allowing it to not be able to function properly. 
* Poison Manipulation: Demonic Power can be used to help one endure against poison.High School DxD Volume 11, Life 4 
* Soul Manipulation: Issei, a low-class Devil at the time, was able to endure attacks from Saji, who was using his own life-force (aka his soul) as Demonic Power to increase the potency of his attacks as well as hitting his soul. Issei was again able to take and endure hits from Sairaorg,High School DxD Volume 10, Life MAX vs Power MAX whose punches can attack the soul itself. 
* Disease Manipulation: Humans who were reincarnated as Devils are incapable of catching diseases that they otherwise would have caught. Likewise, this means illnesses of other Devils who were originally of another race besides a Human may not be able to affect them and thus Natural/Pure-blood Devils can't catch any human diseases and the like.High School DxD, Volume 13, Life 3 
==Weaknesses==
The following are weaknesses that Devils innately possess: 
* Holy Manipulation/Holy-related weapons and powers: Devils have an inherent weakness to anything of holy nature such as light, which ranges from feeling weak while in the sunlight (for newly reincarnated low-class Devils) to the light-based weapons wielded by Angels and Fallen and weapons of Holy-nature like Excalibur.High School DxD Volume 3, Life 2 and the True Longinus.High School DxD Volume 9, Life 4 This applies even further to things such as crosses, holy water, and exorcism. Even Devils who are only born part pure Devil such as Vali Lucifer can be fatally harmed from Holy natured weapons and powers.
** However, Devils with sufficient Demonic Power or of a high-class status and up are capable of enduring and even lessening the effects of holy-related items and the like, in turn mitigating the effects put on them to varying degrees depending on theor class and Demonic Power.High School DxD Volume 2, Life ∞ vs Power ∞ I Came to Keep My Promise!High School DxD Volume 4, Life 1High School DxD Volume 18, Life 4 
* Manipulation of life-force as Demonic Power: While a Devil can use their life force as Demonic Power to increase the potency of their attacks and even hit the soul, this comes at the cost of said lifeforce being drained to the point of potentially killing them.
* Devil-affiliated diseases and illnesses: Although Devils, including those reincarnated that were once Human aren't able to catch colds and illnesses from that of a Human's, they can catch ones that can affect Devils. These specific colds act very similar to ones Humans can catch, with the added side effect of said diseases affecting one's ability to use Demonic Power as well as other effects such as the dampening of their "sixth sense".
