Jessie Musashi

Jessie has very long magenta hair that she wears curled in a comet-tail behind her head. She typically wears a pair of large green pearl earrings that have become a staple signature part of her look and is never seen without them, even in disguise.

Jessie usually wears a customized Team Rocket uniform of her own design. consisting of a short black crop top that exposes her midriff and belly button under a short-sleeve white high collared crop top emblazoned with a large red R that team rocket is known for, a short white miniskirt, grey high-heeled thigh-high boots, and shoulder-length grey gloves. When she is horny, she wears a black Team Rocket-branded micro bikini, black thigh-highs, and red high heels.

Jessie is the short-tempered member of the Team Rocket trio, having a tough streak as well as being vain and very prone to anger. When she steals someone else's belongings or Pokémon, she often says: "Your things are mine, my things are still mine." Proud and haughty, she is excessively self-confident and can’t help seeing herself as the most beautiful, the most talented, and the best in many areas. Due to her pride, she usually underestimates her opponents' strength, which is a cause for her own failure.

She also values her beauty and long hair; she will become furious if her face or her hair is damaged. A prime example is when a younger Scyther manages to slash her hair down to a shoulder-length, devastating her and sending her into a rage. Jessie also shows her violent outrage when someone insults her beauty by calling her old.

Jessie has an affinity for snake-like Pokémon such as her Ekans who later evolved into Arbok and her Seviper. She also makes has a love of Poison-type Pokémon. In addition, she adored her Dustox, which she released. Dratini and Smoochum are her favorite Pokémon too, so she'll try to steal any one of them if she sees one. Despite this, Jessie is shown to care about her Pokémon, proving that her method of training is merely an act of tough love.

She can sometimes be a hopeless romantic, although she is also aware of her own bad temper. So, whenever she falls in love, she pretends to be a calm and delicate young woman to charm the person she likes, while she truly hates showing any sign of vulnerability. If she is moved or touched by an act of kindness, she usually pretends out of pride that it doesn't affect her at all.

Jessie's tough personality subsides due to her promotion to an Advanced Agent. She became calmer and more collected, much more relaxed, and more like a true villain but maintains her mean streak when facing her rivals.

Jessie also loves popularity when she aspires to become a Kalos Queen and became popular with many people.
