*Jinx, born Powder, is one of the main protagonists in Arcane. She is the unpredictable, ingenious, and chaotic little sister of Vi and adoptive daughter to Silco. Throughout the show she is disturbed with feelings of abandonment from her sister, along with the manipulation she faced from Silco as she tries to determine what her true sense of self is.

Jinx is rather pale, which could be attributed to the lack of sunlight in the lanes, as her skin was rosier when she was younger. She also has slightly sharp, sickly facial features. There are constant dark circles under her eyes, noticeable tear burns, and she has 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 when she kidnaps Caitlyn. Her eyes always glow right before her speed and/or strength are activated.

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; 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 small breasts, muscular arms, a small waist, and rather wide hips. She has tattoos on the right side of her body, depicting clouds similar to the ones caused by both the warehouse explosion and also the flare that is given to her by Vi, which she uses after finding out her sister is alive. 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, 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 after the fight with the Firelights. 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.

Jinx is also assumed to be ambidextrous. She prefers to shoot with her left hand but also uses her right hand as a seemingly dominant hand in many other scenes.*
