Third Exorcist Program

Third Exorcists are chosen members of CROW who were biologically engineered into Half-Akumas, by absorbing the akuma cells from Alma Karma who was fused with the shards of Akuma Egg Shell. They gain the power to consume other Akuma and immense strength. While being Ex-CROW members, they can also use magic; charms or spells to be more exact.

Appearance
For the most part, the third exorcists resemble ordinary humans except for their eyes of which pupils tend to change to resemble a more demonic look. During a battle, the 3rd Exorcist's arm will morph into a misshapen claw with a ball of dark matter within the forearm. When being viewed through Allen Walker's left eye, a swarm of dark matter can be seen surrounding them.

History
The previous attempt of using dead Exorcists brains to create Second Exorcists failed and after massacre done by Alma Karma the project was banned from further development and declared the Order's Dark Legacy. But as the Vatican became more desperate to win the War against the Earl the Central gave Renee Epstain permission to improve and experiment on CROW members. The Third Exorcist are created from absorption of Akuma cells within the First Womb - Alma Karma.

When the Noahs break into the Black Order American's Branch and wake up Alma, the Akuma's cells of the Third exorcists gone rogue, infected by Alma's anger towards the Black Order, causing them to turn temporally into monstrous forms. After they returned to normal appearance, the Noah's kidnapped them to use the Third's powers in its own benefit.

When Tyki Mikki and Road Kamelot break into Allen's cell in the Black Order Headquarters to save him from Apocryphos, the Third Exorcists are seen out of the bulding, having absorbed the golems and CROW guards who guard the perimeter. Aparently, thay used spells to allow Road to open a Dream Door into the cell, neutralizing the seals who protected the cell from intrusions. It seems that now thay are under the Noah's control, possibly by brainwashing.

Purpose
The Third Exorcists' purpose is to help Innocence using Exorcists by destroying Akuma. The Akuma cells within the body multiply whenever a third exorcist absorb an akuma, when enough of akuma Cells are produced the Third Exorcist eventually becomes the next Womb and the Cells will be used to make another Third Exorcists.

Powers and Abilities
''note: the power and abilities are of the third exorcists only. For equipment, spell casting etc. move to CROW article''

Immense Strength
Madarao has shown incredible strength, effortlessly blocking a blow from a Level 3 Akuma with his bare hand. Koushi was also able to hurl Allen into a stone pillar with enough strength to partially destroy it.

Akuma Presence
Due to the Akuma cells present in their bodies, Third Exorcists count as Akuma as well, allowing them to pass through barriers only Akuma can penetrate. Allen Walker's Pentacle Eye reacts to the Crow members only when their Akuma abilities are active, but he sees only a dark aura and no bound soul. As a side-effect of being half-Akuma, they react aggressively when they come into contact with Innocence, and may instinctively attack Innocence users.

Cannibalism
Though Third Exorcists possess no Innocence and therefore cannot destroy Akuma through Exorcism, they can invoke the Akuma cells in their body to transform their left arm into a Preta (喰機（ガキ）, Gaki) that allows them to absorb and eliminate Akuma through Cannibalism. Though the name refers to the Preta, "hungry devils" found in Buddhist mythology, the kanji used in the name literally translates to Devouring Mechanism (喰機, Kuki). Below is a listing of abilities that have been performed with it:
 * Gaki Kaibyaku Kō (喰機開闢孔（ガキカイビャクコウ）, lit. "Preta Creation Hole"): The Third Exorcist transforms their left arm, causing their flesh to part away and reveal a core of Dark Matter within their forearm and a hole in their palm, through which they can create a vortex that resembles a black hole. This can be used to absorb an Akuma directly, or to spread a dark shadow across the ground which can drag them down like a whirlpool before drawing them in. After being kidnapped and brainwashed by the Noah, they can also absorb another things, like humans or golems.

Members
After Noah clan abducted Madarao, Tokusa and Tewaku, while Goushi and Kiredori were killed by the hands of Exorcists, there are no new Third Exorcists stationed at the Black Order.

Trivia

 * Unlike average akuma, third exorcists have dark auras around them and are not by any means bound, tormented souls.
 * All third exorcists have dulled human emotions - it's unknown if it's side effect of the experiment, their CROW training, or that they're just stoic in character.
