Im very dedicated to the original 150, but looking back at the show it was clear they hinted at more pokemon with Ho-Oh flying by. I've only recently started opening up to the newer pokemon because the ones like Minccino and that corgi looking one exist
I honestly haven't seen that many of them - but of what I have seen, surely the original is my favorite just based on the nostalgia factor alone. That Pikachu crying scene will never not make me sob like a baby
