Cinder Fall

Crimson (Unofficial) is a character in the world of RWBY. She appears to be affiliated with Roman Torchwick in some way and assists him in the escape stage of a Dust store robbery.

Appearance
Crimson has glowing yellow-orange eyes and wears a dark red dress with yellow designs, her hair is black and her eyes are green with yellow around the edges. She wears high heels and has crystal anklets. Her fingernails are painted dark red. From the short glimpses of her in the first episode, it is possible her appearance is influenced by east Asian culture, as the designs on her dress are styled similarly to traditional Japanese or Chinese patterns. She also wears black shorts underneath her dress. Crimson has high-heeled shoes and a jeweled anklet, with a blue feather-like accessory on her right hip. She has a black tattoo on her upper back that forms a heart shape inside.

Abilities & Powers
She possesses a high degree of skill over Dust that rival, or even surpass, that of Glynda Goodwitch's. She also seems to have a strong command over the Fire element, as seen in the first episode where she continuously used these flame based abilities without difficulty. Her primary technique seems to be a highly forceful blast of flame, which is powerful enough to block and knock back some of Glynda's manipulated debris. She's able to summon pillars of concentrated heat energy to erupt from the ground and she also possesses a powerful blocking technique, capable of easily withstanding Crescent Rose's bullets. Noticeably, her abilities emit a high pitched whistling sound when casting, though this may simply be a typical occurrence for Dust reactions.

Trivia

 * Due to the number of other characters who appeared in the Pilot episode that are seemingly influenced by the 1900 novel The Wonderful Wizard of Oz and its 1939 musical film adaption, such as Ozpin and Glynda Goodwitch, fans have speculated that Crimson might allude to the character The Wicked Witch of the West, as she also possesses abilities (like fellow Dust user Glynda) that are mainly fire-based.
 * Another theory regarding her fairy tale allusion, despite being an antagonist, believes she references the titular character of Cinderella, due to the "cinder" in her name and Crimson's high-heel slippers with an anklet of glass-like crystals, a famed symbol of the story being Cinderella's glass slippers.
