And pokemon that can speak telepathically to human. Realistically Humans shouldn't exist in the pokemon universe at all and an army of Lucario should've been able to exterminate most of the human race.

Use a brain control pokemon to take over entire human cities and have their trainers endlessly breed and release more Pokemon for their army.

It's really a lost concept by Gamefreak to not have a Pokemon game where the main enemy are pokemon themselves.
