Alicia

Alicia is Claymore #1 in both Clare's generation and Clarice's generation. Her identical twin sister Beth is Claymore #2. She is a new type of Claymore made by The Organization and wears a special black uniform, earning her the nickname Alicia the Black (黒のアリシア, Kuro no Arishia). She and Beth are known together as the Black Ones.

Appearance
Alicia wears a special black outfit which is essentially the normal claymore uniform, only black. Her hair is long and straight, with a straight fringe.

In Alicia's Awakened Form, she has bladed appendages on her arms, head and neck. Her special black uniform is also not destroyed when she awakens.

Employment as a Claymore
Alicia is first fully seen in manga chapter 62 when Rubel takes Galatea to see the power of the highest ranked Claymore (she had a brief appearance in chapter 49 with her handler as they gauged Riful's strength in her awakened form). Alicia and Beth are both confronted by some Awakened Beings who threaten to attack her. Galatea tells Rubel that Alicia and Beth will be unable to defeat the Awakened Beings but Rubel tells her of the twins' power. Alicia is able to fully Awaken, while her human soul is contained by her sister via a "soul link". This gives Alicia the strength of an Abyssal one without losing control to bloodlust. Taught only to fight and align their "souls" with one-another to counter the threat of The Powerful Three, they have little personality. Through training, their strength is constantly gauged and raised by the organization. Galatea is shocked and unable to believe it until Alicia awakens and easily kills all the Awakened Beings before returning to her normal state.

After Seven Years
Seven years after this event the Orginization has finally decided to use Alicia and Beth to fight the Abyssal ones. She and her sister follow the Abyss Feeders to the location of Riful. She appears before both Riful and Dauf after their brief battle with the Abyss Feeders. She quickly awakens and attacks Riful but is pinned down under Dauf's arm. Undeterred, she slices through Dauf's left arm with ease and then dodges Riful's attack before momentarily backing off.

Alicia attacks again but her movement is decreased due to Dauf's attack on Beth. However this is only temporary and she again slashes at Riful, slicing off some of her ribbon-like appendages. Her movement again drops when Beth continues to have to evade attacks but the battle is interrupted when the combined Awakened Being of Rafaela and Luciela attacks from a distance. Alicia manages to avoid all the creatures attacks but loses Riful in the confusion. Alicia quickly tracks Riful and the injured Dauf down but is beginning to lose her mind due to Beth having been impaled by the creature's previous attack. She slices through the Abyss Feeders that had surrounded Riful, who appears to realize what is happening. Alicia reverts to her human form in order to use soul-link to keep the now-awakened Beth from awakening permanently.

When Alicia feels Beth struggling against Priscilla she runs to her aid, blocking Priscilla's killing shot. Realizing she stands no chance against Priscilla she Awakens, technically becoming an Abyssal One and preventing Beth and herself from ever returning to their normal states in the process. The pair work together in unison to attack Priscilla, with Alicia managing to slice her side and slice off a leg. Alicia goes for another attack but Priscilla avoids which prompts Alicia to rush at her head on for a second attack. In response Priscilla calmly places her hand on Alicia's head and rips it off in one fluid motion, killing the Organization's number 1.

Personality
Alicia appears to have absolutely no emotions and is completely loyal to the Organization. She obediently reports anything she has done or intends to do and carries out any mission that they ask of her. She rarely speaks and when she does it is only to inform someone of what is going on. According to Rubel she and her sister have 'no sense of self'.

She also appears to care deeply for her sister, despite never expressing it verbally. Alicia had the courage to face Priscilla head-on when the awakened Beth was in danger, and even purposely awoke so the two could work together in the fight after Alicia attempted to make Beth revert with a soul link. According to Priscilla, the otherwise mindless twins gain the qualities of a human when they synchronise, letting them defend each other and feel grief.
