Whether you’re building your competitive team or simply collecting themed avatar items, the celebration provides plenty of reasons to explore during this limited-time window. Let’s break down everything you need to know to make the most of this cross-game celebration.

Event Overview

The Pokémon Legends: Z-A Celebration Event in Pokémon GO runs from Thursday, October 16, 2025, at 10:00 a.m. to Monday, October 20, 2025, at 8:00 p.m. local time. This event serves as both promotion for the upcoming Nintendo Switch title and a meaningful in-game experience that emphasizes Mega Evolution a key mechanic that’s expected to feature prominently in Pokémon Legends: Z-A.

Unlike previous tie-in events that introduced new Pokémon or Shiny variants, this celebration focuses primarily on enhancing existing gameplay elements with increased Mega Raid frequency and special opportunities to obtain powerful starter Pokémon with exclusive moves. The event leans into the Lumiose City theme from the Kalos region, offering avatar items inspired by the trainers from that iconic French-inspired setting.

Event Details

At the heart of this celebration is an event-exclusive Timed Research with branching tasks that lets trainers choose their partner Pokémon. Here’s what you can expect:

• Free Timed Research: Available to all players without ticketing, this research features branching paths that lead to encounters with either Chikorita, Totodile, or Tepig
• Special Backgrounds: These starter Pokémon come with a Seasonal Special Background themed to the current Season of Tales of Transformation
• Bonus Encounters: The first partner Pokémon you choose will have an increased chance to be attracted to Daily Adventure Incense throughout the event
• Additional Rewards: Completing research tasks also earns you XP, Candy, and a Poffin

It’s important to note that this Timed Research has an expiration date, you’ll need to complete the tasks and claim rewards before the event ends on October 20.

Exclusive Moves

One of the most valuable aspects of this event is the return of powerful Community Day moves for the featured starter Pokémon’s final evolutions. These exclusive attacks can significantly enhance your Pokémon’s battle performance.

If you already have these Pokémon in your collection, you won’t miss out Meganium, Feraligatr, and Emboar will also be able to learn their featured attacks using a Charged TM during the event. This provides a fantastic opportunity to optimize existing Pokémon without spending additional Candy on evolution.

Strategic Value of Exclusive Moves

These Community Day moves are considered among the best attacks for their respective types:

• Frenzy Plant is one of the strongest Grass-type charged moves in Pokémon GO, making it essential for any Meganium
• Hydro Cannon similarly stands as a top-tier Water-type attack that significantly boosts Feraligatr’s performance in raids and PvP battles
• Blast Burn provides Fire-type Pokémon with exceptional damage output, making Emboar a more formidable contender in battles

Mega Raids Take Center Stage

True to the Mega Evolution theme anticipated in Pokémon Legends: Z-A, this event significantly boosts Mega Raid activity. Two key opportunities await trainers looking to expand their Mega Evolution collections:

Increased Mega Raids

Throughout the entire event duration, Mega Raids will appear more frequently in gyms . While the specific Mega Pokémon weren’t detailed in announcements, this increased frequency provides more chances to earn Mega Energy for various species.

Mega Rayquaza Raid Day

Mark your calendars for Saturday, October 18, 2025, from 2:00 p.m. to 5:00 p.m. local time for a special Mega Rayquaza Raid Day. This highly anticipated raid day features:

• Increased Shiny odds for Rayquaza encounters
• Up to five additional free Raid Passes from spinning Gym Photo Discs
• Temporarily increased Remote Raid Pass limit of up to 20

Remember that to Mega Evolve Rayquaza, you’ll need to teach it the signature move Dragon Ascent using a Meteorite item. This requirement makes catching a Rayquaza with good IVs during this event particularly valuable.

Style Like a Lumiose City Local

What better way to celebrate the Lumiose City-themed Legends: Z-A than dressing the part? Pokémon GO is introducing six new avatar items inspired by trainers from the game . These items will be available for free in the in-game shop during the event and will remain available after the event concludes:

• Lumiose City Outfit (Fitted)
• Lumiose City Hat (Black)
• Lumiose City Shoes (Red)
• Lumiose City Outfit (Relaxed)
• Lumiose City Hat (White)
• Lumiose City Shoes (Blue)

This approach allows trainers to customize their appearance to match the Parisian-inspired aesthetic of Lumiose City while continuing to show their Pokémon Legends: Z-A enthusiasm long after the event ends.

Competitive Edge

Beyond collection purposes, the Pokémon featured in this event offer genuine strategic value for trainers interested in battles. Here’s how each starter measures up:

Meganium: The Specialized Grass-Type

While Meganium has the lowest max CP (2725) of the three starters, it shouldn’t be dismissed outright. With Frenzy Plant, it becomes a serviceable Grass-type attacker, particularly in Player-vs-Player formats like the Great League where its bulk and coverage move Earthquake can handle Steel-types that wall other Grass Pokémon That said, it faces significant competition from other Grass-types in both Ultra League and Master League.

Feraligatr: The Resilient Water Attacker

With a solid max CP of 3,230 and only two weaknesses (Electric and Grass), Feraligatr presents a dependable option for trainers. Its best moveset combines Water Gun with Hydro Cannon, and it has additional coverage options like Ice Beam to handle Grass-type counters. While it may not top the charts as the premier Water-type attacker, it remains a competitively viable choice with better defensive typing than its counterparts.

Emboar: The Damage Sponge

According to competitive analysis, Emboar emerges as perhaps the most practical choice of the three for trainers seeking a “tankier build that can help buy time with a solid damage output”. When paired with Blast Burn, it can leverage its Fire typing to deliver significant damage while withstanding considerable punishment in return.

Mega Rayquaza: The Ultimate Prize

With a staggering max CP of 6485 and a powerful charged attack in Dragon Ascent (dealing 140 damage), Mega Rayquaza stands as the crown jewel of this event from a competitive perspective. As a Dragon/Flying type, it resists several common attacking types while hitting hard in return. Its primary vulnerability lies in Ice-type attacks, so proper team support is essential.

Preparation Tips for Trainers

To make the most of this limited-time event, consider these preparation strategies:

• Plan Your Evolutions: Identify which Bayleef, Croconaw, or Pignite you want to evolve during the event, and ensure you have enough Candy for evolution
• Stock Up on TMs: Save Charged TMs to teach existing Meganium, Feraligatr, or Emboar their exclusive moves without evolving new specimens
• Coordinate Raids: For Mega Rayquaza Raid Day, prearrange raid groups to maximize your chances of success and conserve resources
• Clear Research Slots: Ensure you have space for the Timed Research when it becomes available on October 16
• Check Your Inventory: Make room for the free avatar items in your inventory and confirm you have storage space for new Pokémon encounters
