The Pokémon Trading Card Game’s Mega Evolution era continues this spring with a new expansion called Chaos Rising. On Thursday, The Pokémon Company confirmed its worldwide release for May 22, with prerelease tournaments scheduled for May 9 through May 17. The set will also launch in Pokémon TCG Live on May 21.
“Trainers will discover Mega Floette ex wreaking havoc as night falls in Lumiose City,” reads the official announcement. “Players can leverage Mega Greninja ex and other powerful Pokémon, including Mega Pyroar ex and Mega Dragalge ex, to ward off this dangerous threat.” In addition to those four new cards, the Pokémon Company also teased a new Espurr card.
The set will include five Mega Evolution Pokémon ex, five Pokémon ex, 11 illustration rare Pokémon, 18 ultra rare Pokémon and Trainer cards, and six special illustration rare Pokémon and supporter cards. Altogether, Mega Evolution—Chaos Rising will include more than 120 cards, including at least 20 trainer cards and more than 35 cards with special illustrations of trainers and their Pokémon.
Chaos Rising is the fourth expansion in the ongoing Mega Evolution block, which began in late 2025. It reintroduced the Mega Evolution mechanic but made it function more like traditional evolution rather than have it trigger with the use of a Spirit Link tool card. This new set follows January’s Ascended Heroes, which featured more than 290 new cards, and Perfect Order, which launches on March 27 with more than 120.
The Mega Greninja ex Special Illustration Rare seems like this set’s big chase card, and there’s some interesting lore connections here. In the Pokémon anime, Ash Ketchum physically fused with his Greninja through a process called Bond Phenomenon. While similar, Ash-Greninja is not explicitly a Mega Evolution. And while Ash-Greninja has appeared on trading cards before, Greninja didn’t get a bona fide Mega Evolution form until 2025’s Pokémon Legends: Z‑A video game. Which means Chaos Rising will deliver the first-ever Mega Greninja in the TCG.
Full card lists and product details have yet to be revealed for Chaos Rising, but it will continue to push the Mega Evolution theme that’s been dominating the game’s current era — and likely give collectors plenty of flashy new chase cards along the way.
