Briar

Briar (ブライヤ Buraiya) is a member of the Black Magic Cult, Avatar.

Appearance
Briar is a fairly tall, curvaceous, dark-skinned woman who has curly eyelashes and thin eyebrows; her long white hair flows freely in the back, but her bangs, however, are slicked upwards, save for one lock which dangles down in front of her forehead. For attire, Briar is scantily clad, wearing a black, polka-dotted cloak (fastened with a brooch of sorts), under which she dons a blue bandeau with tassels. Around her waist, Briar wears nothing but a black loincloth, and up and down her legs are black bands that are crossed for form several X's. On her feet she wears simple black sandals, and she decorates her ears with heart-shaped earrings.

Personality
Briar comes off as fairly relaxed individual, and after having intruded upon Priest Arlock's prayer, her demeanor suggests that she doesn't have much respect for the sacred duties of the cult and its leader. Despite this, she has care for the cult's overall goal: the "Purification Plan"; though her lack of respect for Arlock's prayer time could also be attributed to the fact that the Magic Council has become aware of their intentions, due to a spy being amongst their ranks. However, Briar still puts much faith in her fellow cultists, as they have all spent much time together; she goes as far to even include Gray amidst her circle of trust, all regardless of whether or not he was part of the former number one guild in Fiore, and whether or not his family and close friends were slaughtered by Zeref's Demons. She also has a habit of giving people nicknames that are indicative of their personality or appearance (i.e. Jerome is dubbed "Scruffy" and Mary "Poisontongue").

Avatar arc
During an Avatar meeting, Briar sits at a round table with her comrades, and as Arlock chants to them that the time of Avatar has come, Briar repeats their creed: everything they do is for the sake of Zeref.

After the meeting, Briar ventures to Arlock's private chambers and interrupts his prayers alongside Jerome, supporting his claim that the Magic Council is aware of their plans and adding that they should remove the spy from the cogs of their plan. However, she and Jerome are dismissed by Arlock, and the members of Avatar convene privately, where she defends Gray from Jerome's accusation of being a spy. Then, when Gray reveals that he is using Avatar to get a hold of the Book of E.N.D., Briar notes that his lust of vengeance has turned his soul, as well as his body, pitch-black. She then shows surprise when Jerome tells her that he is okay with his nickname ("Scruffy").

Along with the other cultists, she is quickly alerted at Natsu's call for Gray immediately after infiltrating the Avatar headquarters. During the sacrifice ceremony, Briar puts Jerome's mind at ease about Gray's intentions, saying that whether he betrays them now or not he cannot stop them, and also offers her comrade a new nickname. She is later shocked to see many of her cult members be easily defeated by an unknown force and when she finds out it is Gray and his past friends, she orders her allies to not falter and to blow the enemies away.

Briar watches alongside Mary as Team Natsu decimates the lesser Avatar forces; after she declares that they are the only ones who can stop them, Jerome tells them that he'll take care of the disturbance in the rear. After, she moves forward with Mary, Abel and D-6, and tells them to show their opponents the terror of their Black Magic. Seeing Gray, Briar charges at him, asking how he could betray them. She asks if all the times they had were a lie, to which he tells her of course they were. He says he would never be friends with murderers like them but she says that it is purification, not murder. She then asks if he was lying about the book as well, but he says that he was not and that he will destroy E.N.D.'s book. The two continue to attack each other and Briar says she cannot forgive Gray. As Gray sends a large blast her way, Briar dodges by splitting herself, causing Gray to smile, saying she was finally forced to use her Clone Magic. She is split into 4 distinct personalities, Raging Briar, Grieving Briar, Smiling Briar and Briar in love. Her personalities state she is furious, that she finds it hilarious Gray would pick a fight with them and that she is sad she has to kill him as she had fallen in love with him a bit. Gray is dumbfounded by this but before he can do anything Juvia arrives and proclaims Briar to be her love rival. Juvia uses Water Claw to take out Briar in love before Gray then finishes the rest of the Briars by freezing them. As Natsu finishes off Ikusa-Tsunagi, Briar lies on the ground shocked that Avatar's army was defeated.

Magic and Abilities
Clone Magic (分身魔法 Bunshin Mahō): A Magic that allows Briar to make four copies of herself, each with a personality that embodies a different emotion such as happiness, anger, love, and sadness.
