In Pokémon the Movie: Diancie and the Cocoon of Destruction, James (Kojirō) functions as a member of Team Rocket. He participates in the group's collective effort to kidnap Diancie using a bag, intending to exploit her diamond-creating abilities. Team Rocket persuades Diancie to produce diamonds, resulting in a clock tower overflowing with diamonds until they subsequently disappear. This failure leads to their departure from the scene.
