Yang Xiao Long, daughter of Taiyang Xiao Long and Raven Branwen, grew up on Patch alongside her younger half-sister, Ruby Rose. Raven abandoned the family shortly after Yang's birth, and her stepmother, Summer Rose, died on a mission in Yang's childhood. This loss spurred Yang to seek Raven, culminating in an attack by Beowolves where she and Ruby were rescued by their uncle, Qrow Branwen. This event forged Yang's protective nature toward Ruby and her resolve to avoid letting her search for Raven consume her. Yang maintains a cheerful and supportive personality, often acting as a caretaker for her teammates. She remains fiercely protective of Ruby, encouraging her independence while providing steadfast emotional support. Her approachability surfaces when she facilitates conversations between Ruby and Blake Belladonna early at Beacon Academy. However, Yang possesses a short temper, especially if her hair is damaged or those she cares for are threatened. This anger activates her Semblance, causing her eyes to turn red and her hair to glow fiery, amplifying her strength proportional to damage received. Her primary weapons are Ember Celica, dual shotgun gauntlets usable for both melee and ranged combat. Following the loss of her right arm during the Fall of Beacon, she employs a prosthetic limb later upgraded to incorporate timed explosives. In *RWBY: Ice Queendom*, Yang focuses on rescuing Weiss Schnee from a Nightmare Grimm. After the Grimm induces Weiss's coma, Yang volunteers to enter Weiss's dreamscape with Ruby and Blake. Within the dream, Weiss's perceptions alter Yang's appearance and weapon capabilities, enhancing Ember Celica's power. Yang displays tactical adaptability, surrendering to dream security forces to infiltrate a tower imprisoning dream versions of herself and Ruby. She later remains behind to distract guards while Ruby and Blake advance, following a team decision. Yang supports Blake's risky plan to become voluntarily possessed by the Nightmare, allowing Blake to confront "Negative Weiss" (a manifestation of Weiss's repressed negativity) directly. Yang retrieves a dream relic and distorts the dream world using her motorcycle, enabling Ruby's access to the Nightmare. She subsequently assists in the final battle against the Grimm-controlled Negative Blake, helping to separate Blake from her negative persona. Her relationships define her character. She shares a close bond with Ruby, having trained her in combat during their childhood. She develops a romantic relationship with Blake, confessing her feelings in the Ever After. Unresolved feelings about Raven's abandonment continue to influence her actions, though she prioritizes her found family in Team RWBY.
