When Pokémon don't listen to you it's because you're not far enough in your game (traded Pokémon listen to depending on how far you are in your game). Game Freak didn't want new players to peacefully use powerful Pokémon from their friends who finished the game, so these powerful Pokémon get programmed to use random moves, not do anything, or fall asleep, only when they're traded to weak trainers. If you have finished the main story all Pokémon will listen to you. Also, I could go and test this for you, when I have time. I'm pretty sure it won't listen to you without completing the main story, but that's only if it's at a high level, if it's at a low level, it will listen to you because it's like your other Pokémon, until it isn't.
