Players of Pokémon Sword and Pokémon Shield hit the one million Trainers defeating Zeraora target and as a result, a Shiny Zeraora will be distributed on Pokémon Home for one week from June 30th, 2020 until July 6th, 2020 at 23:59 UTC to players that qualify.

Earn a Shiny Zeraora and Armorite Ore in Pokémon Sword and Pokémon Shield

If one million Trainers defeat Zeraora in a Max Raid Battle, players can receive a special Pokémon along with items that will be useful in The Isle of Armor.

The Isle of Armor, the first part of the Pokémon Sword Expansion Pass and the Pokémon Shield Expansion Pass, has arrived! To celebrate the release of this new chapter in the Pokémon Sword and Pokémon Shield adventure, players of those games can participate in Max Raid Battles against the Mythical Pokémon Zeraora.

From Wednesday, June 17, 2020, at 8:00 a.m. PDT until Sunday, June 28, 2020, at 4:59 p.m. PDT, Zeraora will appear in Max Raid Battles, so gather your friends as you attempt to take down this Mythical Pokémon. Zeraora has the potential to appear in three-star Max Raid Battles or higher, and in five-star Max Raid Battles, there's a chance that you'll encounter an especially powerful Shiny Zeraora. You won't be able to catch Zeraora after it's defeated, but if at least one million Trainers manage to defeat Zeraora during this special event, a Shiny Zeraora will be available to everyone in Pokémon HOME.

In addition to Shiny Zeraora, every player who takes part in these Max Raid Battles will receive a piece of Armorite Ore for every hundred thousand Trainers that defeat Zeraora after the first million is reached (up to a maximum of 10 pieces). Armorite Ore can be used in the dojo on the Isle of Armor to have your Pokémon learn moves.

If the target numbers are reached, you'll be able to claim your Shiny Zeraora and Armorite Ore via the Mystery Gifts menu in the mobile device version of Pokémon HOME from Monday, June 29, 2020, at 5:00 p.m. PDT until Monday, July 6, 2020, at 4:59 p.m. PDT. Note that you don't have to have the Expansion Pass to encounter or receive Zeraora. In order to claim these gifts, you must also meet the following condition:

You must have deposited a Pokémon in Pokémon HOME or moved a Pokémon to Pokémon Sword or Pokémon Shield from Pokémon HOME between Wednesday, June 17, 2020, at 8:00 a.m. PDT and Monday, July 6, 2020, at 4:59 p.m. PDT.

Note: Linking with Pokémon Sword and Pokémon Shield is a feature available only in the Nintendo Switch version of Pokémon HOME. For more details, please visit the Pokémon HOME section of the Pokémon Support website.

Assemble your best team to battle this Electric-type Mythical Pokémon, and help players from all over the world reach one million victories! And be sure to check out The Isle of Armor, the first part of the Pokémon Sword Expansion Pass and the Pokémon Shield Expansion Pass, available now!
