galarian zapdos, articuno, and moltres are a different species of pokemon like toadscool and wiglett, the people naming them just guessed their names wrong
so are the implications of greavard's pokedex saying "a dog Pokemon that died in the wild was reborn as this pokemon" implying that it used to be a maschiff?
you may fight over what you think the best zelda is but I think it's worth pointing out nintendo chose one specific game to represent the entire series
it may not be immediately apparent because we're used to the anime, but since ultimate used to be the final stage before the anime it's crazy agumon originally just died and became a cyborg zombie
