Mew Jirachi Diamond Pearl

As well as the Legendary Pokémon that will be available in Pokémon Brilliant Diamond and Shining Pearl's post-game, as revealed by The Pokémon Company earlier today, you'll also be able to get your hands on two Mythical Pokémon.

Both Mew and Jirachi will be available in-game, regardless of which version – Brilliant Diamond or Shining Pearl – you opt to play. To get them, you'll need save data from past Pokémon games on the same Switch system – here's how it works:

Mew

To get Mew in Pokémon Brilliant Diamond and Shining Pearl, you'll need save data from Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! on your system.

Speak to a madame in the flower field located on the southwest end of Floaroma Town to add Mew to your team.

Jirachi

To get Jirachi in Pokémon Brilliant Diamond and Shining Pearl, you'll need save data from Pokémon Sword and Shield on your system.

Speak to a gentleman in the flower field located on the southwest end of Floaroma Town to add Jirachi to your team.

It appears that you're able to obtain both Mew and Jirachi on the same save file, as long as you meet the requirements for each mentioned above. However, even if you have save data for both Sword and Shield, for example, you'll still only be able to obtain one Jirachi (and the same applies for Mew).

Nintendo has today confirmed that Brilliant Diamond and Shining Pearl will receive a patch before launch that you'll definitely want to make sure you download.
