To celebrate the release of The Crown Tundra, the second part of the Pokémon Sword Expansion Pass and Pokémon Shield Expansion Pass, players can receive a plethora of Pikachu, each wearing one of Ash Ketchum's iconic caps from Pokémon the Series. In fact, once you receive these Pikachu in your Pokémon Sword or Pokémon Shield game, take a look at the Pokémon's Original Trainer—yep, these are Ash's Pikachu!
You'll get Pikachu wearing some of Ash's caps from throughout the animated series, ranging from his classic chapeau from when he first set out on his Pokémon adventure to more recent designs—like those seen in the film Pokémon the Movie: I Choose You! and the current season of the TV show, Pokémon Journeys: The Series. See below for the full list of Mystery Gift passwords.
Use these steps, along with one of the above passwords, to receive each form of Ash's Pikachu.
Launch your Pokémon Sword or Pokémon Shield game.
Select Mystery Gift on the X menu.
Select Get a Mystery Gift.
Select Get with Code/Password to connect to the internet.
Enter your password.
Watch as the gift arrives in your game. (Pokémon will appear in your party or your Pokémon Boxes.)
Be sure to save your game.
You do not need to have purchased the Pokémon Sword Expansion Pass or Pokémon Shield Expansion Pass to claim any of these forms of Ash's Pikachu, and you can receive each of these forms only once in a single save file. Also, please note that Ash's Pikachu cannot evolve. Likewise, Ash's Pikachu cannot be fed Max Soup, which is featured in The Isle of Armor (part one of the Pokémon Sword and Pokémon Shield Expansion Pass). Each of these passwords must be entered into your Pokémon Sword or Pokémon Shield game by November 30, 2020, at 6:59 a.m. PST, so don't wait, Trainers!
