Niantic has officially revealed powerful new Adventure Effects for Zacian and Zamazenta as part of the grand finale of Pokémon GO Fest 2025: Global — the most anticipated event on the Pokémon GO calendar.
The two Galar region legends—already favorites among Trainers—are getting significant upgrades through a mechanic that could change how players approach raids and Max Battles during and beyond GO Fest.
⚔️ Crowned Forms Debut With Enhanced Abilities
Originally introduced in 2021, Zacian and Zamazenta entered the game in their Hero of Many Battles forms. Their Shiny variants only became available in 2024, during the Legendary Heroes and Galarian Expedition events. But in 2025, Pokémon GO stepped it up: Trainers can now unlock Crowned Sword Zacian and Crowned Shield Zamazenta, each with a signature move and exclusive Adventure Effect.
🌟 Zacian’s Adventure Effect: Behemoth Blade
To activate Zacian’s Adventure Effect:
-
Zacian must be in Crowned Sword Form.
-
Its Charged Attack Iron Head is replaced by Behemoth Blade.
-
Spend 5,000 Stardust and 5 Zacian Candy to trigger the Adventure Effect.
➡️ Effect: For 6 minutes, your Pokémon’s attack power is boosted during Raids and Max Battles. This makes Zacian an elite attacker—especially useful in high-level raid rotations during GO Fest.
🛡️ Zamazenta’s Adventure Effect: Behemoth Bash
Similarly, Zamazenta gets a major boost:
-
Must be in Crowned Shield Form.
-
Its move Iron Head is replaced with Behemoth Bash.
-
Pay 5,000 Stardust and 5 Zamazenta Candy to activate.
➡️ Effect: Your team’s defense is strengthened in raids and Max Battles for 6 minutes, making Zamazenta a critical support for coordinated group play.
🌍 Timing and Availability
Both effects go live during GO Fest 2025: Global, serving as the event’s final highlight. Trainers worldwide will be able to experience these legendary powers across raids, battle leagues, and group events. Expect to see both legends take center stage in PvE and PvP meta discussions moving forward.
🧠 Strategy Tip: When to Use Adventure Effects
Adventure Effects like Behemoth Blade and Behemoth Bash do not stack, so choose wisely when to activate them. Ideal moments include:
-
Entering a Tier 5 or Mega Raid
-
Engaging in Team GO Rocket Takeovers
-
Coordinating in Max Raid Battles with friends
These time-limited boosts could be the difference between a win or a wipe.
With the debut of Crowned Zacian and Zamazenta Adventure Effects, Pokémon GO Fest 2025: Global is shaping up to be one of the most strategic and rewarding events ever. Whether you’re a collector, battler, or Explorer-type Trainer, there’s never been a better moment to engage with these Legendary Pokémon in a whole new way.
Be sure to prep your Candy, Stardust, and teams — because the Crowned Legends are ready to lead the charge.
