"Pokémon GO" players witnessed one of the rarest catches in the game's history during GO Fest Tokyo, where a trainer successfully caught a shiny 100% IV Shadow Groudon.
The moment quickly went viral within the community, spicing things up in the in-person GO Fest events ahead of Pokémon GO Fest Global 2026.
The rare encounter took place during a 5-star raid and was captured on video by popular "Pokémon GO" content creator FleeceKing, whose live reaction helped amplify the moment across social media platforms.
Shadow Groudon Becomes One of the Strongest Raid Rewards
Shadow Groudon is already considered one of the most powerful Shadow Pokémon in Pokémon GO due to its significantly boosted attack stats. Combining that strength with a shiny variant and perfect IVs makes it an exceptionally rare and highly sought-after Pokémon for both collectors and competitive battlers.
The addition of a special Tokyo-themed background, exclusive to GO Fest ticket holders, further increases its value, tying the Pokémon directly to the live event experience.
The Odds Behind a 'Shundo' Shadow Legendary
According to GameRant, the statistical rarity of the catch highlights just how extraordinary the moment is. A shiny Legendary raid encounter typically has odds of around 1 in 20, while a perfect IV Legendary stands at approximately 1 in 216.
When combined, the chance of obtaining a shiny perfect Legendary, commonly known as a "shundo," drops to roughly 1 in 4,320.
This makes the shiny Shadow Groudon one of the rarest possible outcomes in "Pokémon GO" raid gameplay, explaining the widespread community reaction.
A Milestone Moment for a Top Player
FleeceKing, already known as the first player worldwide to reach Level 50, added another major milestone to his record with this encounter. What's even more interesting is that he did it during the live stream.

'Pokémon GO' Fest 2026 Builds Momentum
Following Tokyo, in-person GO Fest events continue in cities such as Chicago and Copenhagen, leading up to "Pokémon GO" Fest Global in July 2026.
Upcoming events are expected to feature Legendary raid rotations, new Mega Evolutions, and potential Mythical Pokémon debuts that could change the current meta.
Meanwhile, PlayerOne reported that there's a "Pokémon GO" limited-time event for massive collectors. If you have been a part of the community for so long, you know that Shiny Pokemon are one of the prized pieces for collectors.
Although the idea of having many Shines feels like a minute dream, the actual process of catching them isn't easy.
