I mean, why would pokemon be on the side of team rocket or whatever other villainous (often apocalyptic) group the games have? They just follow whoever catches them no matter what.

Have you never heard of police dogs?

There’s a documentary that may help explain this, iirc it’s called Paw Patrol

Why wouldn’t they? Team Rocket/MagmAqua/Galactic/Plasma/Flare all have pokemon fighting with them. They listen to the trainer, not the moral obligation of the society.

I’ll give you Venusaur but Charizard is a dyed in the wool fascist.
