Chaos Rising, featuring Mega Greninja ex, has now been revealed. As reported previously, the set will release on May 22, 2026 as the fourth English Mega Evolution expansion.

Prerelease events will take place from May 9 through May 17.
Chaos Rising will include:

Chaos Rising will contain 122 cards and will be an almost exact replica of Japan’s Ninja Spinner expansion, which releases on March 13.
The Japanese set contains 120 cards, making the English release only slightly larger.
Japan has not been releasing subsets recently, which means English expansions are currently being built from fewer Japanese source sets. Because of this, Chaos Rising is relatively small.
Like Phantasmal Flames and Perfect Order, it will be one of the smallest English sets released since 2010.
With global Pokémon TCG shortages, it’s possible Creatures Inc. is intentionally designing fewer new cards. This could allow the company to increase print volume for those cards or allocate printing capacity to other products.
However, this remains speculation.
