Perhaps more so than any other Pokemon game before it, Pokemon Legends: Arceus really encourages players to catch them all. This task is a lot easier said than done, however, with 242 Pokemon available throughout the entirety of the game. 85 of these are tied to the game's very first region, the Obsidian Fieldlands, though it is worth noting that Shaymin can also be found here if players have Sword & Shield save data on their Switch.
