Cinder Fall[2] is one of the main antagonists of RWBY 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. Her machinations are the driving force behind the events of the first 3 volumes of RWBY.

In "Heroes and Monsters", Cinder becomes the new Fall Maiden, granting her vast power. However, in "End of the Beginning", Ruby Rose unleashed an attack of unexplained nature using her silver eyes, enveloping Cinder in a blinding flash of light. "The Next Step" revealed that she lost her left eye, with massive scarring over that side of her face. Cinder is also shown to have incredible difficulties speaking, barely being able to voice a single word at a time. Due to this, Emerald initially acts as Cinder's aid when she needs to communicate verbally. In "Dread in the Air", Cinder is revealed to have regained most of her vocal control.

In "Downfall", she is defeated and frozen by Raven Branwen as she falls into the abyss, leaving her fate unknown
