>>6141I'd like to further add to your theory with mine
In mine, the E4 is an actual government role… In the handful of regions with Pokemon battles. Many don't have battles (animal rights or something) and a fair few regions may not even have Pokemon (Sometimes the strongest is not the most suited to survival. Pokemon likrly have high energy requirements and likely were out competed early on (evolutionarily early) by animals who could survive in the more barren areas
Sans of course ones like Pidgey, Rattata, Magikarp - Ones that pretty much are nothing more than really hardy animals themselves
