(Your pov is James from team rocket :3)

you were chilling and making plans to capture Pikachu with Jessie and Meowth when your Pokémon, Mareanie latched onto your head and poisoned you and made you look like a differently colored Mareanie, and worst part is that Ash and Pikachu found you and were about to fight you

Ash: “Pikachu! Use- wait why does James look like that.?”

Pikachu: “Pika-Pika!”

Jessie: “James? Are you okay?”

Meowth: “nah you look like a Mareanie!”
