Larxene
Larxene, the Savage Nymph is number XII in Organization XIII, and it's only female member. She is the lowest on the Organizations numbering system after Roxas, number XIII. She plays a large role in Sora's storyline during the events of Kingdom Hearts: Chain of Memories.
Vexen and Axel
Soon after Vexen battles Sora to observe him, Marluxia and Larxene begin to doubt his sincerity. They decide to compel Vexen to pursue Sora by threatening to tell "the Superior" of the failure of the Riku Replica, despite Vexen's confusion at the orders, since Sora's death would ruin Marluxia's plans to use him against the Organization's head members. Although Vexen is number IV and Marluxia number XI, Marluxia had been given authority control over the castle; this coupled with Vexen's fear of Xemnas compels him to engage Sora in a simulated Twilight Town. Vexen fails, and plans to tell Sora about Roxas in order to break Marluxia's plans for controlling Sora. Axel cuts him off by killing him just before he speaks, having been ordered to eliminate him as a traitor to the conspiracy. When Axel returns, Larxene says that they hadn't been sure if Axel would have done it; in this way, Axel earns the trust of both Larxene and Marluxia.
Personality
Although Larxene is normally smiling and even winking at times in-game, she has a cruel, sadistic personality and enjoys seeing others suffer hardships and anguish. She taunts Vexen incessantly after he is threatened with charges of treason and incompetence from Marluxia, and toys with Sora before fighting him the first time. After she discovers Axel's betrayal and sees that her and Marluxia's plans have fallen apart, her smile vanishes and she attacks Sora in a rage.
Fighting Style
Larxene uses a set of kunai that can act as a pair of claws as well as formidable throwing weapons. And though she can levitate and teleport, she also possesses very formidable agility that is a step up above the other Organization members, giving her good reason to be called the "Savage Nymph".
Along with her physical skills, her use of magic is deadly as well. She can summon bolts of lightning to rain down from the sky, in a focused form as well as one that strikes a large area. In addition, she can also bind a person in place with tendrils of lightning, allowing her to get in powerful blows.
