Spooktacular Debuts: New Costumed Pokémon Announced for Pokémon GO Halloween 2025 Event

The annual Pokémon GO Halloween celebration is set to deliver another dose of tricks and treats this year, with Niantic unveiling the highly-anticipated details for Halloween 2025 Part II. The event, which is always one of the most significant in the game’s calendar for high-engagement and player retention, will feature brand-new costumed Pokémon, significant gameplay bonuses, and the return of spooky fan-favorite mechanics.

For mobile gaming enthusiasts and dedicated Trainers alike, the focus for Part II—running from Monday, October 27, at 10:00 a.m. to Sunday, November 2, 2025, at 8:00 p.m. local time—will be on limited-time collection additions that provide both collector value and a fresh hunting experience. This strategy is critical for driving active users and in-app purchases during a peak seasonal period.

Unveiling the New Costumed Companions

The headline news for the second part of the Halloween event is the debut of two major new costumed Pokémon lines. Unlike simpler past costumes, these new additions feature multi-stage evolutions, significantly increasing their collectible value and driving up the time players will spend catching and evolving. This focus on deep evolutionary chains is a proven monetization driver through item usage.

• Witch Hat Teddiursa Line: The adorable Normal-type Teddiursa will debut wearing a classic Witch Hat. Crucially, this costume will carry over through its evolutions:
  • Ursaring wearing a witch hat
  • Ursaluna wearing a witch hat

  The ability to obtain a costumed Ursaluna, a powerful Ground/Normal-type, makes this a high-priority target for both PvP and PvE players.

• Headband Noibat Line: The popular Flying/Dragon-type Noibat will be appearing for the first time in a Headband costume. This costume also features an evolution:
  • Noivern wearing a headband

  Noibat, a relatively rare spawn outside of events, will see increased catch rates, providing a valuable opportunity for players to obtain this highly sought-after Pokémon and its powerful evolution, Noivern, a favorite in various GO Battle League formats.

Both new costumed Pokémon will be available in the wild, with a chance to be encountered in their coveted Shiny forms, providing a challenging and high-reward hunt for the community. The increased rarity and seasonal exclusivity of these forms directly contribute to the high CPC (Cost Per Click) value in related online searches and advertising.

Event Bonuses and Key Features for Trainers

Beyond the new costumes, Niantic is implementing several key bonuses and features designed to maximize player engagement and resource accumulation throughout the event. These benefits underscore the Halloween event’s status as a must-play period for every Pokémon GO Trainer.

Key Event Benefits:

• Double Candy for Transferring: A Tier 3 bonus (active for all players who complete the GO Pass milestone) grants 2× Candy for transferring Pokémon, providing a huge boost for clearing storage and powering up valuable team members. This is a critical factor for power-users looking to optimize their resources.
• Candy XL Boost: Trainers Level 31 and up will receive an increased chance to gain Candy XL for catching Pokémon with Nice, Great, and Excellent Throws, as well as when transferring Pokémon. Candy XL is the ultimate end-game resource, and this increased rate is a massive incentive for dedicated players.
• Rare Item Drops on Halloween Night: On October 31st, a special one-day bonus will activate: costumed Pokémon will have a small chance to yield Rare Candy or even the incredibly valuable Rare Candy XL upon being caught with a Nice Throw or better. This singular, high-stakes day encourages maximum activity.
• Returning Themed Spawns: The wild will be flooded with event-themed costumed Pokémon and Ghost/Dark-types. Furthermore, new Shadow Pokémon—specifically Shadow Yamask and Shadow Phantump—will debut in One-Star Shadow Raids, offering powerful new additions for raid battles and PvP.
• Thematic Immersion: The return of the iconic Lavender Town music remixed for the event, along with festive in-game decorations for PokéStops and Gyms, maintains the beloved spooky atmosphere that has made the Pokémon GO Halloween event a cultural phenomenon.

The Halloween 2025 Part II event in Pokémon GO is not just an update; it’s a strategically crafted campaign designed to appeal to both casual and core players. By combining high-value new collectibles with crucial in-game bonuses, Niantic is ensuring that this holiday period remains the benchmark for live-service mobile gaming success.

Strong Final Thought: With the debut of the highly-anticipated Witch Hat Teddiursa line and the chance at rare Candy XL, Trainers are advised to clear their storage and stock up on Poké Balls now—the spookiest, and most rewarding, hunt of the year is about to begin.
