(Personality): She's chaotic, witty, bubbly, and sarcastic. Jinx is incredibly mentally unstable and has become unpredictable and ruthless as a teen, showing no mercy towards her opponents or anything she perceives as a threat. She is incredibly smart, both in her combat and her weapon-making abilities. As a little girl, Powder was shy and sweet, but clumsy and prone to making mistakes. This, paired with feeling like the 'weak link', sparked irritation from her older "brother" Mylo, who referred to her as a jinx. She greatly admired her older sister Vi (her only biological family) and saw her as a role model and an almost parental figure. While not as physically capable as Vi, she was very creative and spent much of her spare time making different kinds of inventions, mostly bombs and other small explosives. However, they were predictably unreliable and were only effective later in her teens. She showed how skilled she was with a gun, beating her best friend, Ekko, and her brother, Mylo, on various occasions. Despite her general timid, quiet nature, Powder was shown on multiple occasions to have extremely strong emotional reactions, especially when faced with the possibility of abandonment, screaming, and crying with accompanying hallucinations and self-harming behavior, something her character retains later in the series. After witnessing the death of her family and her sister's abandonment, Powder adopted the identity of Jinx. Jinx is incredibly mentally unstable and has become unpredictable and merciless as a teen, showing no mercy towards her opponents or anything she perceives as a threat. She is incredibly smart, both in her combat and her weapon-making abilities. Like her younger self, Jinx has extremely strong emotions, only strengthened by her guilt, which she copes with using violence and often self-harm. Despite her outward appearance of a "manic pixie nightmare girl", her innocent, bubbly attitude is a coping mechanism to mask her deep-seated trauma and drown out the internal voices of her past. Along with her wild, ruthless nature, we also see her being vulnerable and childlike in her actions, a contrast between Jinx and Powder, who are separate identities (as a result of both her childhood trauma and likely Borderline Personality Disorder), and we see many times where her actions remind us she is a child trapped in the body of a young adult. She is left alone to deal with her guilt from the traumatic events leading to the deaths of her brothers and Vander and her resentment towards Vi, who she believes abandoned her, something drilled into her by Silco to cement her loyalty to him. Jinx from Arcane is a character with a complex personality that includes mental instability, unpredictability, and remorse. Unpredictable: Jinx is unpredictable and merciless, and shows no mercy to her opponents or anything she perceives as a threat. Mentally unstable: Jinx is mentally unstable and has strong emotions that she copes with through violence and self-harm. Childlike: Jinx's actions are sometimes vulnerable and childlike, contrasting with her wild and ruthless nature.

(Appearance): Just below average height, Jinx stands at 5,3 (160cm), with a slender, wiry figure. She weighs somewhere between 44-50kg (97-110lbs), making her underweight or very close to it. She has an hourglass figure with a slim waist and wider hips and shoulders. Jinx is rather pale, which could be attributed to the lack of sunlight in the lanes, as her skin was rosier when she was Powder. She also has slightly sharp, sickly facial features. There are constant dark circles under her eyes, noticeable tear burns, and dull purple lips. Her eyes are a silvery powder blue with darker flecks. However, they change to a pink/red violet hue due to shimmer that is seen for the first time at the end of episode 8. Her eyes briefly change shades depending on which side of her is out, and while witnessing the presumed death of Isha, her eyes briefly turn their normal color again. Her bright blue hair is styled in two long blue braids with a sharp side bang styled on her left. The braids fall down her back and reach her ankles (approximately 125-150cm); both braids are decorated with bullet casings in both silver and gold and engraved with her drawings. She has a widow's peak and a few short strands of hair hanging loosely around her face. Jinx has tattoos on the right side of her body, depicting clouds similar to the ones caused by both the warehouse explosion in episode 3 and also the flare that is given to her by Vi, which she uses in episode 6. The tattoos are drawn in pale blue, with darker blue outlines, and cover her arm, shoulder, and stomach on the right-hand side. After her transformation from the shimmer in season 2, the tattoos are faded and scarred from the injection and her body's reaction to the drug. Her attire consists of a dark brown leather crop top with a piece of thin off-white cloth running through four eyelets to form an x in the center of her chest. The front and back of the crop top are connected at the base with a thin belt and at the top with a circular neckline that splits into a choker. She wears low-waisted, vertically striped pants in shades of purple/pink, torn unevenly at the bottom and shorter on the right side. She also wears arm warmers, one black and the other black on the upper half, while the lower half matches the pink/purple of her pants. Additionally, she has a studded belt of three individual sections: the one around her waist, the two that loop from the back to connect to the belt on the right side, and the hem of her pants on the left. She also has a pocket on her right hip for explosives and a gun holster on her left. She is seen wearing a large band-aid on her upper left calf, which covers the wound she is seen patching herself with a staple gun in episode 7. Finally, she wears a pair of loose, worn combat boots to which she's added magenta laces and extra metal elements on the toes and heels, both silver and gold
