Pokémon Legends: Arceus has 242 Pokémon in its Hisui Pokédex when fully completed, including all post‑game and special save‑data bonuses.

Quick Scoop

  • The official Hisui Pokédex tops out at 242 entries when everything is unlocked.
  • This total includes:
    • Regional Hisuian forms (like Hisuian Zoroark and Hisuian Typhlosion).
* Several brand‑new species introduced specifically for Legends: Arceus.
  • Some mythicals only appear if there is save data from other Switch Pokémon titles on the console, but they still count toward the 242 figure when available.

In forum discussions, players sometimes mention “240” when they don’t have the cross‑game save bonuses, but the complete Legends: Arceus experience is widely agreed to be 242 obtainable Pokémon in total.

At the time of writing, Pokémon Legends: Z-A has only been announced and its exact Pokédex size has not been confirmed, so any specific number for how many Pokémon will be in Legends: Z-A would be speculation based on comparisons to Arceus and the Gen 6 Kalos Pokédex.

TL;DR: For the closest current reference to Legends Z-A , Legends: Arceus features 242 Pokémon in its regional Pokédex when fully completed.
