Weiss Schnee is one of the main characters and the second character introduced in RWBY. Weiss' weapon of choice is a Multi Action Dust Rapier (MADR) named Myrtenaster.
Weiss appears as a young girl, dressed primarily in light blue, white, and some red. She wears a pale blue bolero jacket over a similarly colored thigh-length dress with a piece of black lace making up the neckline of the dress. The inside of the bolero is red and the sleeves turn blue as they get closer to her wrists. The back of the bolero displays the Schnee Crest, which bears a resemblance to a snowflake. The same design seems to appear when she uses her Semblance. According to Weiss, her dress is a combat skirt, which Ruby Rose also wears.
Weiss wears an apple-shaped necklace along with a pair of thin, rectangular earrings. She wears white, heeled wedge boots that go to mid-calf; the insides are also lined with red. Her long white hair is pulled back in an off-center ponytail, at the base of which is a small tiara that resembles icicles. She has a pale complexion and ice blue eyes. She also bears a crooked scar down her left eye.
