The Halloween event has become one of the most popular annual celebrations in Pokémon GO. Every year, the event introduces spooky-themed Pokémon spawns, Ghost- and Dark-type bonuses, costume Pokémon, shiny debuts, and special rewards that attract both casual and hardcore players.
Unlike smaller in-game events, Pokémon GO’s Halloween celebration usually runs in multiple phases and includes raids, research tasks, collection challenges, and increased candy bonuses. Over the years, the event has also become known for introducing highly anticipated Pokémon and exclusive costume variants that are often unavailable outside Halloween.
Because the event changes slightly each year, many players want to know what they should realistically expect when Halloween season arrives in Pokémon GO. From boosted Ghost-type spawns to bonus Candy and rare shiny opportunities, the Halloween event consistently offers some of the best rewards of the year. Let’s break down how Pokémon GO Halloween events work, the types of bonuses usually included, and what players should prioritize during the event.
Halloween Events Usually Focus on Ghost- and Dark-Type Pokémon
One of the defining features of Pokémon GO Halloween events is the increased appearance of Ghost- and Dark-type Pokémon. Pokémon like Gastly, Haunter, Gengar, Misdreavus, Litwick, Phantump, Zorua, Drifloon, and Sableye frequently appear during the event.
Niantic confirmed that Halloween 2025 Part I included themed wild encounters such as Zorua, Hisuian Zorua, Greavard, and Sinistea, continuing the event’s tradition of spooky Pokémon spawns. The event also introduced Poltchageist and Sinistcha into Pokémon GO for the first time.
Ghost-type Pokémon become especially valuable during Halloween because many of them have strong raid or PvP relevance. Pokémon like Gengar and Chandelure remain useful attackers, while Spiritomb and costume Pokémon are often highly sought-after collector targets.
Halloween events also tend to increase shiny encounter opportunities. Niantic’s Halloween 2025 announcement confirmed boosted access to shiny Pokémon like Sinistea during the event period.
Because of these spawn rotations, Halloween is often one of the best times of the year to farm Ghost-type Candy and shiny Pokémon simultaneously.
Candy Bonuses Are Usually the Biggest Reward
Candy bonuses are one of the main reasons players heavily grind Pokémon GO Halloween events every year. Halloween events traditionally include boosted Candy rewards for catching, transferring, or hatching Pokémon.
Niantic’s Halloween 2025 event details confirmed multiple Candy-focused bonuses, including 2× Catch Candy and increased Candy XL opportunities for higher-level trainers. Later stages of the event also added boosted transfer Candy bonuses.
These bonuses are extremely valuable because Candy is essential for powering up Pokémon, unlocking second Charged Moves, and evolving rare species. Players often save large Pokémon inventories specifically for Halloween transfer bonuses because the extra Candy can dramatically reduce grinding time.
Ghost-type Pokémon are particularly useful for this because many evolve into powerful raid attackers or PvP Pokémon. Farming Gastly Candy during Halloween, for example, allows players to build stronger Gengar for raids and Mega Evolution usage.
Candy XL bonuses also matter significantly for endgame players trying to max out Pokémon beyond level 40. Halloween events frequently become one of the best opportunities of the year to farm XL Candy efficiently.
Costume Pokémon Are a Major Part of the Event
Costume Pokémon have become one of Pokémon GO Halloween’s signature features. Each year usually introduces new themed costumes alongside returning fan favorites.
Halloween 2025 Part II featured costumed Pokémon like Teddiursa wearing a witch hat and Noibat wearing themed accessories, according to Niantic’s official event announcement.
Costume Pokémon are popular because many become limited-time collectibles. Some costumes never return after their original event, making them highly desirable for collectors and shiny hunters.
Shiny costume Pokémon are especially valuable because of their rarity. Niantic also confirmed increased shiny encounter rates for certain costumed Pokémon during Halloween raids in 2025.
The downside is that some costume Pokémon cannot evolve, which limits their gameplay usefulness. However, for collectors, the exclusivity and rarity often matter more than competitive viability.
Because costume Pokémon frequently dominate event spawns, Halloween events tend to appeal strongly to players focused on shiny collecting and Pokédex completion.
Raids and Special Research Usually Bring Rare Pokémon
Halloween events also significantly affect raids. Ghost- and Dark-type raid bosses typically become more common, and special event raids often feature rare or shiny-capable Pokémon.
Mega Gengar frequently returns during Halloween because it fits the event theme and remains one of the strongest Ghost-type attackers in Pokémon GO. Darkrai and Giratina also commonly appear during Halloween raid rotations.
Polygon’s Halloween event coverage noted that Halloween events consistently rotate themed raid bosses and costume Pokémon into raids during the seasonal celebration.
Special Research and Timed Research are another important part of Halloween events. These research lines often reward encounters with rare Pokémon like Spiritomb, Yamask, or costume Pokémon unavailable elsewhere.
Research tasks also typically provide bonus Stardust, Mega Energy, and event encounters, making them an important source of progression during the event period.
Because many Halloween-exclusive Pokémon appear through research rather than wild spawns, completing event tasks is usually essential for fully participating in the event.
Halloween Events Often Introduce New Pokémon
One major reason Pokémon GO Halloween events attract so much attention is because Niantic frequently debuts new Pokémon during the event.
Halloween 2025 introduced Poltchageist and Sinistcha into the game, continuing the tradition of spooky-themed debuts. Previous Halloween events introduced Pokémon like Greavard, Zorua, Pumpkaboo, and Phantump.
These debuts are important because newly released Pokémon are often difficult to obtain after their launch event ends. Some eventually become rare seasonal spawns or disappear entirely until future events.
Niantic typically designs Halloween events to emphasize mysterious or supernatural Pokémon, making the event one of the franchise’s strongest thematic celebrations. This consistency helps maintain player excitement every year.
For collectors, Halloween often becomes one of the most important annual events because it combines new Pokémon, costume variants, and boosted shiny opportunities in a single update cycle.
What Players Should Prioritize During the Halloween Event
Because Halloween events include so many bonuses simultaneously, players benefit most when they focus on specific goals.
Candy farming is usually the highest priority because the event’s bonuses dramatically improve progression efficiency. Catching Ghost-types with Pinap Berries during double Candy bonuses can produce huge resource gains.
Shiny hunting is another major focus. Halloween events frequently feature boosted shiny rates for select Pokémon, especially costume variants and newly released species.
Raid participation is also important because Ghost- and Dark-type Legendary Pokémon often return during the event. Giratina, Darkrai, and Mega Gengar are among the most useful raid Pokémon regularly associated with Halloween.
Inventory management matters as well. Many experienced players save Pokémon transfers for Halloween transfer Candy bonuses to maximize efficiency.
Finally, players should prioritize event-exclusive research tasks before the event ends, as these often provide encounters unavailable outside Halloween.
