They work together to block Ash Ketchum and his team from succeeding and they try their best to get their hands on Pikachu. Although Ash isn't always the perfect kid , he still has better intentions than these bad guys. Jessie, James, and Meowth don't follow the rules of the Team Rocket organization That is most likely why they always struggle to come out on top. It's surprising that Giovanni doesn't just cut them loose! They even get married and have kids together.
Jessie, Meowth , and James are a group of independent field agents that operate beyond the Team Rocket organization's reach. When they encounter villains opposed to their personal or organizational goals, the three are usually more than willing to sabotage the evil team, even to the point of assisting Ash and his allies when they finally recognize the threat. Though they are dedicated, the trio is not entirely loyal to Giovanni, and instead, treat the assignments he gives them as means to their own ends. Jessie functions as their confident leader, who allows them the freedom to have side jobs and hobbies and doesn't flinch when lying to their boss' face.
The duo are partners under Team Rocket's command, but fans often wonder if there's something more to their relationship, whether they're secretly in love or outwardly dating. In the show's fiction, the two met at the Team Rocket Academy, where they formed a team with Meowth and pledged to stay by each other's sides. Whether they have feelings for each other in the anime series is less explicit.
In the anime, they are the primary antagonists and the most frequently appearing members of Team Rocket. They joined Team Rocket separately and were on initially unfriendly terms after being grouped with Meowth but they quickly made up and became good friends. After their first defeat at the hands of Ash 's Pikachu convinced them of his extraordinary power, the trio made their main goal to capture Pikachu.
