Yoma

Yoma are beings that feed on human flesh and blood. They can shape-shift into human form that allows them to live among humans. The Organization creates them by rounding up orphan boys and sending them to the North while the girls are sent to the East to become Claymores. They are created by combining the flesh of both a humanoid and an "Awakened" Asarakam, which forms a parasite with transfigurative abilities that is capable of infecting the brains of unsuspecting human hosts. The end result is a Yoma.

Yoma have strength and speed beyond humans and can regenerate damaged bodies at incredible speeds. Yoma in their true state have golden cat-like eyes, razor sharp teeth and claws, muscular, elongated limbs and torsos, purple blood and brown, purple, gray or green skin.

Normal Yoma
The most common and least powerful, they are the main source of revenue to the Organization. These Yoma vary in appearance in skin color and build, varying from lean to bulky but always muscular with long torsos.

They and their Flying and Awakened kin have sharp teeth and a predatory attitude to match. Most have rows of stubby spikes growing from their upper backs, with elongated limbs that end in clawed digits.

Yoma are recently confirmed to be created by corrupting normal human beings using the flesh of a species called Asarakam, also referred to as the descendants of dragons. This species can exist in 2 states, the unawakened state, and the awakened state. Once awakened, the particular individual can never change back. The Organization has imprisoned 2 such beings, one awakened and one unawakened. By shaving off pieces of flesh from each and combining the two, it transforms into a parasitic "wriggling something" that can infect the brains of normal human beings.

Th exact mechanism of the infection is unexplained, it could be replacement of the brain by the parasite, or the brain may still be intact but corrupted by the parasite, or the parasite might be merged with the original brain to form a new personality.

Flying Yoma
Winged, they differ from normal Yoma by their flying ability, thus presenting a greater challenge. Claymores have speared them from street-level or rooftop by hurling swords.

But if a Claymore can jump high enough and has the skill, Flying Yoma can be attacked in midair. Flying Yoma make infrequent appearances in Claymore scenes.

Claymores
Claymores can be considered half-Yoma (except Clare, who is one-half her original self, one half Teresa thus one quarter Yoma, though her right arm is from Ilena, a regular Claymore).Claymores are known also for their long lasting youth and life-span.

Properly trained Claymores have a tactical advantage over Yoma, despite the Yoma's greater strength and number, as Claymores are trained in the martial arts since childhood (Extra Scene 4) and make more skilled use of their yoki (brains over brawn). Claymores also have the ability to sense the yoki of Yoma or other Claymores, sometimes across great distances.

Awakened Beings
Outside the Organization, a third type of Yoma, known as "Voracious Eaters," are alleged to be long-lived Yoma of extreme power and appetite. But this spin is meant for public consumption.

Within the Organization itself, they are called Awakened Beings, former Claymores who have lost control of their yoki, changing into a massive Yoma-like form, and far more powerful than either Claymores and normal Yoma. As with normal Yoma, their appearances vary widely. Some Awakened Beings have animal shapes, while others look like enlarged normal Yoma with specialized traits, such as Dauf.

Abyssal Ones
Awakened Beings that were former No. 1 Claymores. Abyssal Ones' form and abilities are similar to those of lesser Awakened Beings and Normal Yoma, but are vastly more powerful—strong enough to control an entire quadrant of the Island World of Claymore.

Abyss Feeders
According to Dietrich, after the disaster of the Northern Campaign, the Organization began a new line of research that reulted in the Abyss Feeders. Using the bodies of the 11 Awakened Beings killed by Alicia outside of the Organization's headquarters, the scientists implanted pure Awakened flesh into human girls and created monsters in human form, the reverse of Yoma and Claymores, who are humans that eventually attain monster form.

The Feeders are blinded, have their mouths sewed up, and only respond to nearby movement. They are designed to hunt down and destroy Abyssal Ones, like Riful and Isley, through tracking their scents like bloodhounds.

The Destroyer
A unique entity, The Destroyer is formed from the merged bodies of an Abyssal One (Luciela of the South) and a Claymore (Rafaela), accidentally Awakened by Clare. Deneve senses the Destroyer to be more powerful the Abyssal Ones.

However, since it possesses no will of its own, the Destroyer can be entered and controlled as Clare does when her body and mind are assimilated into the creature's mass, using the Destroyer to attack and seal Priscilla (Scene 104).

Parasitic Rods
Rod-shaped projectiles fired by the Destroyer. Parasitic Rods grow into Yoma-like creatures, resembling Luciela's Awakened "hell-cat" form. Clare calls them lifeless automatons—parasites needing a host to reproduce that function on a finite amount of energy.

Behind the Scenes

 * Yoma can disguise themselves as humans by eating their brains to absorb their memories and look like the human they devoured.
 * Normal Yoma can form alliances with Awakened Beings.
 * Overwhelming rage mixed with sexual ecstasy is why Claymores find it difficult to control Awakening.
 * When Awakened male Claymores change to human form, they look like adults in their 20–30s, such as Isley, Rigaldo and Dauf.
 * Human forms of Awakened female Claymores can range from “tweens” such as Riful or Priscilla, to a woman in her 20s such as Agatha.
 * Not eating for extended periods can cause an Awakened Being's body to degenerate, but consuming flesh will reverse the process. This is shown by Priscilla, who reverted to a child-like form after having not eaten for seven years, then reverting to an adult appearance after consuming the inhabitants of a village razed by the Destroyer's parasitic rods.
 * As with other predators such like lions and tigers, Yoma have preference for their prey's internal organs. Muscle meat is eaten last if at all.
 * Eventually, some Claymores (Teresa and Miria) come to suspect the Organization of controlling and even creating Yoma. This is later proven correct, when it is revealed that Yoma are the product of infecting humans with a parasite created from the flesh of two captured members of the Dragon's Kin. Instead of the Yoma taking on the appearance and memories of the devoured, as was initially stated, the parasite afflicts its host with an intense hunger for human flesh, and jumps from host to host as its current body degenerates from reckless transformations and overuse, transforming the new host into a Yoma.
