Are all of you retarded? Oh wait, it's veepee, that's a given, but there's no way your brains are completely lacking in thought.
Just because Pokemon debuted in a certain game doesn't make them native to that game's region. We already know this with the likes of Yungoos, Galarian Zigzagoon, Copperajah, etc. Knowing this, why are you so insistent on calling Pokemon featured prominently in Galar, "Kanto Pokemon?" In universe, for all we know those Pokemon were first discovered in Galar, or even at the same time. You can argue "Kanto pandering" all you want, but when talking about how things are percieved IN UNIVERSE, there's no basis to say that Kanto Pokemon are more popular than Pokemon native to Galar because there's no evidence that "Kanto Pokemon" like Gengar and Machamp were ever known to be associated with Kanto in particular when speaking purely in universe. These Pokemon have existed for thousands of years, likely before the establisment of any civilization in these locations, this argument is just retarded.
