Yang's voice actress, Barbara Dunkelman, has said that when Yang's character was described to her, she was described as "the kind of person who would teach someone how to swim by pushing them in the water". This speaks volumes about how Yang approaches most things in life. She is very straightforward and confident.

Yang is also described as being a cheerful, energetic and bright young lady. She is arguably the most flippant, carefree and adventurous member of her team, frequently making sarcastic comments and jokes even in the heat of battle and often taking combat and hostile situations lightly. Yang is very sociable and extroverted, even in unfamiliar situations. Yang's love of adventure is the main reason she decided to become a Huntress. Blake considers Yang the personification of the word "strength".

However, Yang's "brawler" fighting style is evocative of her personality. Her anger, one of her main assets in battle, can lead her to act predictably. When her hair is cut during battle, her resulting anger leads her to attacking with straight, blunt force. Additionally, a grudge against Neopolitan led to frustration on Yang's part, which quickly cost her the battle and almost her life. Her thoughtless anger led to the quick loss of her right arm in a short encounter with Adam Taurus.

Despite these things, Yang is deceptively mature. She is extremely nurturing, particularly toward her younger sister, Ruby. Yang pushes her into being outgoing and also worries a great deal about her sister across the many battles they fight in. This protective and encouraging nature extends to Blake and Weiss as well. Yang is worried for Blake on several occasions, such as when she runs from her team and when she suffers from sleep and appetite problems, opening Yang to discussing her stubborn past. What Yang does not reveal is that she suffers from abandonment issues, blaming herself for her mother not sticking around.
