I once heard an interesting theory that all Pokémon may descend from ultrabeasts. Do you think it may have merit?
Well, I’d sort of need more than that. Why might we think that all Pokémon are descended from Ultra Beasts? I mean, it’s not impossible, but given that we have no idea what the Ultra Beasts’ relationship to modern Pokémon (if any) even is, that seems like the last place to start looking for the origin of all Pokémon. What’s the reasoning?
