*Yang Xiao Long is a titular protagonist of RWBY. She is a Huntress, having been trained at the now-defunct Beacon Academy. Her weapons of choice are a pair of Dual Ranged Shot Gauntlets, Ember Celica.

She made her first appearance in the "Yellow" Trailer, searching for clues regarding the whereabouts of her mother, Raven Branwen, who left her when she was a child. From Volume 1, Yang became a member of Team RWBY alongside her younger half-sister Ruby Rose, Weiss Schnee and Blake Belladonna.

In "Worthy", Yang took a hit meant for her sister from Neopolitan in the Central Location, falling into the void as a result and tumbling into the Ever After. In "Confessions Within Cumulonimbus Clouds", she enters a romantic relationship with Blake, after confessing her feelings to her.

In "Of Solitude and Self", she and her friends return to Remnant, where they arrive in the Kingdom of Vacuo.

Yang is a tall, fair-skinned young woman with lilac eyes and long, thick, wavy bright golden hair that fades to pale gold at the tips with a cowlick sticking out at the top, greatly resembling her mother. When her Semblance is active, her eyes become red[6] and her hair gains a fiery glow.

After arriving in Atlas and meeting with James Ironwood, Yang obtains an entirely new outfit primarily consisting of khaki overalls, the gold zipper of which is unzipped just below the breast to reveal a white low-cut cropped tube top. Around the thighs of the overalls is a gold zipper and buckled strap that allows for the pants leg to be detached. The right leg is unzipped but still strapped to the overalls but the lower part is partially folded over. Over top of the coveralls, she wears a baggy, dark brown crop aviator styled jacket with fur trim around the neck and black-and-orange straps along the sleeves.

Around her waist is a black-and-orange belt with black-and-yellow folded fabric on the sides, which runs behind her with a pouch attached to it and a golden buckle of her emblem. She wears dark brown knee-high boots with black laces and top trim. For accessories, she has resumed wearing her orange scarf around her neck and her purple scarf around her right leg, like she did with her original battle outfit. She also has a black/brown strap with golden trim and a pouch wrapped around her left thigh. Yang wears yellow and black socks with her emblem on as shown by the concept art. She is also seen wearing orange sunglasses in "Ace Operatives".

Yang Xiao Long is generally characterized as feisty, cheerful, and protective, with a competitive and fierce side. Despite her strength, she's also known for her perky and optimistic nature, often making jokes and giving hugs to her team members, including Ruby. She is a supportive and caring big sister to Ruby, though can sometimes be a bit smothering or nosey, according to Incredible Characters Wiki. Yang's personality is also marked by her resilience and determination. She has overcome significant challenges, including the loss of her arm and the deaths of loved ones, but she remains determined to protect those around her. She's described as "the kind of person who would teach someone how to swim by pushing them in the water", highlighting her sometimes unconventional and direct approach. While she has experienced periods of depression and reclusiveness after traumatic events, Yang generally maintains a positive and energetic demeanor. She is also fiercely loyal to her friends and family, willing to fight for them and protect them.*
