Two Pikachu you have never been able to catch before land on your map this week, and both come with a hard expiration date. To mark the 2026 Pokémon World Championships in San Francisco, Niantic is rolling out a fresh pair of costumed Pikachu across two back-to-back Pokémon GO events — and once the tournament wraps on August 30, these exact outfits disappear into the vault with every other retired costume. If you collect costumed Pikachu, this is a short, high-stakes window.
Here is the practical rundown: what the two new variants look like, the precise dates each one is catchable, how to actually get them, whether they can be shiny, and the small handful of Worlds-themed merch worth grabbing before it sells through. Costumed Pikachu rotate fast, so treat every date and rate below as accurate at the time of writing and always confirm against the live in-game event screen before you head out.
Meet the Two New Pikachu
This year's Worlds celebration debuts two entirely new Pikachu costumes, and they lean into very different vibes.
Cosmog Spacesuit Pikachu. The first variant wears a spacesuit themed after Cosmog, the tiny nebula Pokémon. It's the softer, spacier of the pair — a rounded little astronaut helmet and star-flecked suit that plays off Cosmog's cosmic look. Per Pokémon GO Hub's event coverage, this one shows up across both halves of the celebration, making it the more catchable of the two.
Crowned Championship Pikachu. The second variant is the flashy one: a Pikachu decked out in a crown and cape, styled as the reigning champ of the competitive scene. This is the classic "World Championships Pikachu" archetype that Niantic revives with a new design most tournament years, and 2026's crowned-and-caped take is exclusive to the Worlds portion of the event.
Both are cosmetic-only forms — the outfit is baked into that specific Pikachu and can't be added, removed, or transferred to a Raichu. If you evolve one, you lose the costume and get a plain Raichu, so most collectors keep them exactly as caught.
The Exact Dates (Two Events, Not One)
The celebration is split into two rolling windows, and which Pikachu you can catch depends on which window you're in. All times are local.
PokémonXP runs from Tuesday, August 25 at 10:00 a.m. through Friday, August 28 at 10:00 a.m. This is the warm-up event, and it's your first shot at the Cosmog Spacesuit Pikachu.
2026 Pokémon World Championships runs from Friday, August 28 at 10:00 a.m. through Sunday, August 30 at 8:00 p.m. This is when the Crowned Championship Pikachu joins the party, while the Cosmog variant continues to appear, per the official Pokémon GO event page.
The takeaway: the Cosmog spacesuit Pikachu is available across the full stretch, but the crowned Champion is only catchable during that final roughly three-day Worlds window. If you can only play one weekend, make it August 28 to 30 so you don't miss the rarer of the two.
How to Actually Catch Each One
Costumed Pikachu reach you through a few reliable channels, and knowing which one an event leans on saves a lot of aimless walking.
Wild spawns. The most common method. During both windows, the featured Pikachu simply appear on your map as wild encounters. Drop an Incense, pop a Lure on a busy stop, and stack your walking around the highest-density area you can find.
Raids. The Cosmog spacesuit variant appears in raids during the celebration, which is great news for two reasons: raids give a guaranteed catch encounter with more forgiving catch mechanics, and they're one of the best places to chase a shiny thanks to premier-ball bonuses.
Field Research and Timed Research. Event PokéStops hand out tasks that reward a guaranteed costumed encounter — far more reliable than praying for a lucky wild spawn. On top of that, this year has a Watch & Earn layer: viewers who watch the Worlds broadcast on the official Pokémon GO Twitch channel unlock Timed Research with rewards that include special Pikachu encounters and an Elite Charged TM.
GO Pass rewards. The free progression track offers encounters with event-themed Pokémon, and the paid Deluxe track (starting around five dollars) upgrades those rewards. If you're a completionist, the pass is a low-effort way to bank extra encounters.
One practical note before a long hunting session: this kind of multi-day event grind absolutely chews through a phone.

Can They Be Shiny? What We Know
Both the Cosmog spacesuit Pikachu and the crowned Championship Pikachu can appear as shiny, according to the official event listing. Niantic rarely publishes exact costumed-Pikachu shiny rates, so treat the odds as roughly the standard boosted-event ballpark rather than a guaranteed number — anything in that range is far better than the base rate but still means a lot of taps.
A few shiny-hunting habits pay off here. Prioritize the raid encounters for the Cosmog variant, since the guaranteed catch removes the risk of a shiny fleeing. Check every single wild spawn during the crowned-Champion window, because that variant's catchable stretch is short and there's no second event to fall back on. And if you're chasing both shinies, budget your Incense and Lures toward the Worlds weekend when both are potentially on the table.

Beyond the Game: Worlds-Themed Merch
The World Championships aren't just an in-game event — they anchor a wave of tie-in products that tend to sell out fast once the tournament ends and the exclusivity kicks in. If part of the appeal for you is owning a physical memento of the 2026 celebration, a few categories are worth watching.
Plush. Pokémon Center has been rolling out event-themed plush around this year's championships, and costumed-Pikachu plush in particular hold their value once retired. General Worlds-adjacent and cosmic-themed → Shop Pikachu plush on Amazon options are the easy entry point if the official drops sell through before you get there.
Trading card supplies. Championship season is peak time for TCG players, and a lot of GO collectors cross over. If the event nudges you toward the physical card game, protecting your pulls with quality → Shop Pokemon card sleeves and binder on Amazon supplies is the sensible first purchase.
Everyday carry. Costumed-Pikachu energy translates well to the stuff you use daily. For fans who want to rep the mascot without hunting down a limited drop, our roundup of the best Pikachu phone cases and tech accessories points to pieces you can actually buy today and use long after the event closes.
A Quick Game Plan for the Week
If you take nothing else away, here's the compressed version:
- August 25 to 28: Start catching the Cosmog Spacesuit Pikachu during PokémonXP. Hit raids for a shiny shot and clear the event research for guaranteed encounters.
- August 28 to 30: Prioritize the Crowned Championship Pikachu — this is the rarer, shorter-window variant. Check every wild spawn and keep the Cosmog hunt going in parallel.
- All week: Tune into the official Twitch broadcast for Watch & Earn Timed Research, and keep a charger handy.
Costumed Pikachu are, at heart, timestamps — a permanent little record of where you were and what was happening the week you caught them. The 2026 crowned Champion and Cosmog astronaut are this year's entries, and after August 30 they become memories you either have in your collection or don't. It's a short week. Go get both.
