J/Character

J is ruthless, relentless, and cruel, willing to do anything to capture Pokémon for her clients, up to and including injuring innocent people or Pokémon. In her debut episode, she chose to drop some of her to their potential deaths without hesitation or remorse, emphasizing her intensely independent, sociopathic, greedy and callous nature. She has no honor, decency or regard for any form of life - the only thing that matters to her is money. She is one of the very few characters (including the Iron-Masked Marauder, Dr. Yung, Grings Kodai, and Alva) in the anime who is purely evil.

J is also highly pragmatic. She is reluctant to harm Pokémon that she is trying to capture - as they would be less valuable to her clients - and she will forgo direct combat in favor of sneak attacks and mass destruction if the opportunity presents itself. This contributes to her high threat level in the series. However, she also tends to underestimate her opponents when on the verge of victory, which often leads to her defeat and ultimately ensures her (seemingly) final downfall.

Out of all of the characters that encountered her, she has a dislike for the most as evidenced when he kept on interfering with her job and the fact that most of the encounters had Ash nearly killed or severely injured had it not been for the unlikely intervention of  and Pokémon, and other characters supporting the protagonists.
