They say that they are saving the pokemons and that they are giving pokemons freedom. As I stated before, they appear in almost every episode of the series. It is because they are looking for a specific Pikachu. They are looking and trying to capture the Pikachu that Ash has and not any other Pikachu. I believe that this is not a coincidence. Professor Oak who created the Pikachu that Ash has use to work under Team Rocket as a scientist. It is highly likely that the failed experiment caused by Professor Oak was conducted in a lab from Team Rocket. Since Pikachu goes out of control and destroys the lab, it could have caused Professor Oak and Team Rocket to lose data on the experiment they were conducting. Professor Oak could have fled to a small town where Team Rocket would not find him taking the Pikachu with him. If Team Rocket somehow knew that the Pikachu that went out of control was special, they would want to capture it to get data from it since their lab was destroyed. This is why I think Team Rocket aims to capture a specific Pikachu which it is the Pikachu that Ash got from Professor Oak when he started his journey. Ash started his journey at a very young age and the people of the small town where he grew supported
