Pokémon Legends: Arceus is ripe for DLC, but the fate of any future content is up in the air after Gen 9 games, Pokémon Scarlet and Violet, were announced to be released later this year.

The current Legends: Arceus Pokédex sits at just under 250 species, so there are plenty of other Pokémon available
