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 black hair, glowing yellow-orange eyes and she wears a dark red dress with yellow designs. 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. Whenever she uses her Dust abilities, designs on parts of her body like her arms, back, and chest light up.

Abilities & Powers
She possesses a high degree of skill that rivals, or even surpasses, that of Glynda Goodwitch. She also seems to have a strong command over the element of fire, as seen in the first episode where she made extensive use of 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 also possesses the ability to summon pillars of fire that erupt from the ground, as well as a powerful blocking technique, easily capable of withstanding Crescent Rose's bullets (this blocking technique may be Aura based, but this is unconfirmed). Noticeably, her abilities emit a high pitched whistling sound when cast.

She also possesses some piloting ability, as she was able to control the airjet during one of Glynda's attacks.

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 of the Wicked Witch of the West, as she also possesses abilities (like fellow Dust user Glynda) that are mainly fire-based.
 * Additionally, her high-heel slippers could be a reference to the ruby slippers from The Wizard of Oz, which in the novel were actually silver.
 * She may also allude to Cinderella. Her shoes seemed to be made of a glass-like crystal and her fire-based powers could allude to the 'Cinder' part of Cinderella's name
 * She is possibly the first character seen using Aura, although the existence of Aura wasn't known until Episode 6.
 * Since her debut in the first episode, Crimson has not appeared in any other episode, with the opening credits only showing her silhouette, alongside two other mysterious characters.
