To tie in with the 20th movie, Pokémon the Movie: I Choose You!, another special promotion has begun in Japan. If you prebook tickets in Japan, you will get a serial code that can be used to unlock one of six Pikachu wearing one of Ash’s caps from over the years. The latest distribution provides Kalos Cap Pikachu, which has Ash’s hat from the X and Y series of the anime and knows the move Iron Tail, which Pikachu can’t normally get in Sun and Moon. This Pikachu also comes with the special Pikashunium Z Z-Crystal, which turns the move Thunderbolt into the Z-Move 10,000,000 Volt Thunderbolt. This distribution is available until June 26, 2017, with a repeat scheduled for September.
