Never miss with the Master Ball—coming soon to Pokémon GO!

Trainers,

In the course of your travels, you may have heard of the very best Poké Ball with the ultimate level of performance—the Master Ball. When used, it will catch any Pokémon you encounter in Pokémon GO without fail, whether it be in the wild, through Lure Modules, after Raid Battles, or while using your Daily Adventure Incense.

This powerful item will soon be available to all Trainers in Pokémon GO. What will you use it to catch?

Seasonal Special Research: Let’s GO

Throughout Season 10: Rising Heroes, free Special Research will be available. The final story will begin on May 22, 2023, at 10:00 a.m. local time. Willow’s back with some news on Team GO Rocket’s latest plans…and a gift.

You’ll be able to claim the Special Research until the end of Season 10: Rising Heroes, on June 1, 2023, at 10:00 a.m. local time. Trainers who complete the research will get a Master Ball as one of the rewards.

Receiving a rare and powerful Master Ball is a special occasion—think wisely about how you’ll use it, and keep a lookout for future opportunities in Pokémon GO to acquire more!
