and the primary antagonist of the Beacon Arc. She is a member of a small group of people with malicious goals led by Salem and the leader of her own group. Her associates include her subordinates Mercury Black and Emerald Sustrai, the criminal Roman Torchwick, and Adam Taurus, a high-ranking member of the White Fang. Cinder relishes in dominance and gloating. She displays shameless schadenfreude toward those she has affected, and she is outwardly strict with her subordinates. Although she refers to her partnership with Roman as "cooperation", it is obvious she has the upper hand. Cinder expects her subordinates to execute exactly as she wishes with what little she gives them. She does not seem to tolerate failure, seen with Roman, preferring for her goals to be successful regardless of the situation. Cinder prefers that such problems be solved quickly, is seen to give very direct orders and keeps Roman on a strict need-to-know basis. Cinder is overconfident, so new conflict elements do not faze her. Despite this, however, in the rare occurrence in which she is caught off guard, Cinder's monumental temper surfaces, showing her immense shock and outrage,This shows just how little she thinks of others, feeling that none have the right to pass judgment on a superior being such as herself, indicating that she is amoral, seeing no point to limiting oneself or ambitions based on a code of ethics. In this way, Cinder proves that she is willing to do anything to achieve power, even forsaking her own humanity, seeing herself already as being beyond Human. Cinder's arrogant and confident demeanor also brings out a tendency of hers to gloat in the face of her enemies, her compulsion to bask in her enemies' defeats and her own triumphs consistently leads to her own defeats.
