Following the surprise announcement of Nihilego’s arrival during the Pokémon Go Fest 2022 virtual event in early June, several other Ultra Beasts will appear during the in-person celebrations. A different Ultra Beast will appear in each of the three unique locations during these paid events, giving players a chance to catch these rare Pokémon.
The Pokémon Go Fest 2022 events will take place at different times in personal locations in Berlin, Seattle and Sapporo. Berlin will be from July 1st to 3rd and Pheromosa will appear. Seattle will be July 22-24 and Buzzwole will appear. Finally, Sapporo will take place from August 5th to 7th and Xurkitree will appear.
Alongside these events, Beast Balls will appear as a new item obtainable from Rhi, the member of the Go Ultra Recon Squad that first appeared during the Pokémon Go Fest 2022 event in early June. When Nihilego came out, Beast Balls weren’t available, and Berlin will be the first time we’ll see them in action. These items are said to help a player catch an Ultra Beast, but we don’t know if it’s an exclusive item that can be used in raids in place of the Premier Balls, or if they make it easier to catch an Ultra Beast after you’ve she has defeated a five star raid.
There are also multiple bonuses for each of the three events. All locations can hatch eggs halfway, and there will be event-related field research, snapshot surprises, stickers, and confetti. In addition, four additional special trades will be available and trades will cost less, along with four collection challenges for the event.
On day two, City Session, nine daily raid passes will be available to all participants, and Team Rocket balloons will spawn more frequently and drop twice as many mystery components. Cowboy Hat Snorlax and Unown A, B, E, L, R, S, T, and U will spawn during events.
Pheromosa, Buzzwole, and Xurkitree will be available at a later date during the Pokémon Go season, which ends September 1st.
