New Pokemons not belonging to an index

[sineao]

how is it about new added pokemons (specific for scarlet/violet)? There were already some existing ones added to the game, but they are not a part of the pokedex (charizard, greninja...), is there a way to still get them based on the game? (also perserrker for example which exists from the beginning but isnt a part of the pokedex)

Question is more because now they added two completely new ones, which arent even available at all in the api (or at least i could not find them):
