Pokémon TCG — Mega Evolution: Chaos Ascendant (May 22, 2026)

Mega Evolution — Chaos Ascendant (ME04) is the fourth main expansion in the Mega Evolution block launched in October 2025. The official France release is scheduled for Friday, May 22, 2026, alongside other international markets.

ME04 headline Pokémon

Three cards often drive pre-release talk: Mega Greninja ex, with high competitive potential in Standard; Mega Floette ex, highly sought after by collectors and for its story tie-in; and Mega Chesnaught ex, spotlighting the Kalos starters. The set advertises 120+ cards, including 35+ special illustrations.

Special Illustration Rare Supporter cards tied to Legends Z-A may especially interest collectors: strong narrative weight and a bridge effect between the video game and TCG.

Collector tip — The window around May 22 has historically been when supply is most abundant for chase cards; always compare price per pack and pull expectations on rateTCG before stacking displays.

Competitive impact and pre-releases

Mega Greninja ex should weigh heavily on the Standard meta after ME04. Support cards like Secret Box and Pecharunt ex remain sought-after staples, also found in the Mega Lucario ex League Battle Deck. Play! Pokémon pre-releases let you test the format before street date.

TCG products to watch in May 2026

Early May may bring premium collections (e.g. Mega Zygarde ex–focused), then the main May 22 wave with the Chaos Ascendant line. Prices below are indicative (MSRP / market at time of writing) — check Amazon listings and our price page for current amounts.

  • Mega Zygarde ex Premium Collection — early May — ~€49.99 — collectors
  • ME04 single booster — May 22 — ~€5.99 — all profiles
  • ME04 36-pack display — May 22 — ~€180 — bulk / cautious investors
  • Chaos Ascendant ETB (9 boosters + accessories, Mega Greninja theme) — May 22 — ~€55.99 — players and collectors

ME04 is the block's fourth expansion; ME05 Black Night is announced for July 17, 2026. On the Japan side, a lead of several weeks over Western sets often helps anticipate which premium illustrations gain consensus.

Pokémon GO: indicative May 2026 calendar

May 2026 falls within the Memories in Motion season (official title may vary by translation), with a high density of events. The slots below are a synthesis — Central European time, subject to Niantic announcements.

Community Days

  • May 9, 2–5 PM — Lechonk Community Day: first notable Shiny chance; evolve during the event (or extended window) to target an exclusive move on the final evolution — check the exact move on the GO blog on the day.
  • May 16, 2–5 PM — Community Day Classic Deino: prepare evolutions before community closure to get the exclusive move on the final evolution line.

Raids and Mega Raids (month overview)

  • May 2 (2–5 PM) — themed raid day (e.g. Shadow / legendary raids TBC).
  • May 6 → 13 — 5★ and Mega Raid rotation (e.g. Necrozma / Mega Camerupt per official schedule).
  • May 9–10, 16–17, 23–24, 30–31 — Shadow Cresselia windows in Shadow raids if the weekly cycle holds.
  • May 13 → 20 — regional Ultra Beast rotation (Buzzwole / Pheromosa / Xurkitree) + associated Mega Raid.
  • May 20 → 27 — Tapu Bulu in 5★ raids; May 27 → June 3 — Tapu Fini.
  • May 23 (2–5 PM) — Super Mega Raid Day: first appearance of Mega Hydreigon (confirm in the GO client).

Legendary Raid Hour usually runs Wednesday 6–7 PM (Europe) on the featured Pokémon. Dynamax Mondays 6–7 PM chain different bosses each week (e.g. Cottonee, Growlithe, Registeel, Combee on weeks 1–4 of the month — indicative list).

Tip — The May 9 weekend may stack Community Day, end of a raid rotation, and Shadow raids: load up on passes and storage before the window opens.

Pokémon Legends Z-A — May 2026 news

Released in October 2025 on Nintendo Switch (and Switch 2 compatible), Pokémon Legends Z-A sets Lumiose City as the playground, with real-time battles and the return of Mega Evolution in a main-series RPG.

  • Backward compatibility / catalog: any Classics-style re-release remains TBC on the eShop and Pokédex transfer restrictions.
  • Generation X: Pokémon Winds and Pokémon Waves were presented as the next main-series titles, with no release date at time of writing.
