Pokémon Chaos Rising UK: What It Is and Where to Buy (2026 Guide)
Chaos Rising (ME04) is the fourth Pokémon TCG Mega Evolution expansion, released worldwide on 22 May 2026. Two months on, UK restocks are still selling through fast and Mega Greninja ex remains one of the most hunted chase cards of the year.
If you have seen Chaos Rising trending and wondered whether it is a new set, it is not: it has been on shelves since 22 May 2026. The searches are being driven by ongoing restock-hunting, UK supply keeps selling out while the Mega Greninja ex chase holds serious value. Here is what the set actually is, what is in it, and how to get it in the UK.
What Is Chaos Rising?
Pokémon TCG: Mega Evolution, Chaos Rising is the fourth main expansion of the Mega Evolution series, marketed under the set code ME04 (Limitless uses the code CRI). It was officially announced by The Pokémon Company on 12 March 2026 and released worldwide on 22 May 2026. It is the English release of the Japanese set Ninja Spinner, which launched in Japan on 13 March 2026.
The set continues the Pokémon Legends: Z-A and Kalos theming of the series: Mega Greninja ex gathers other Mega Evolution Pokémon ex, including Mega Pyroar ex and Mega Dragalge ex, against a threat, with Mega Floette ex framed as the antagonist. The card count is 122 cards: 86 base cards plus 36 secret rares, broken down as 18 Ultra Rares, 6 Special Illustration Rares and 1 Mega Hyper Rare. The English set also adds cards that were not in Ninja Spinner: Mega Gallade ex(from Japan's January 2026 Mega Gallade ex Special Set), Krookodile ex and the Trainer card Adversity Policy. The sealed lineup covers:
- Booster box: 36 packs, each with 10 cards, a Basic Energy and a TCG Live code
- Elite Trainer Box: 9 packs plus a promo, sleeves, dice and accessories (a Pokémon Center exclusive version also exists)
- Booster bundle (6 packs), 3-pack blisters and Build & Battle Boxes

Key Cards and Chase Pulls
The headline card is Mega Greninja ex, a Water-type Stage 2 with 350 HP that evolves from Frogadier. Its Mortal Shuriken ability lets you discard a Basic Water Energy to place 6 damage counters, and its Ninja Spinner attack hits for 120+, up to 200. It appears three times in the set: as a regular ex (22/86), as an Ultra Rare full art, and as the set's only Mega Hyper Rare gold card (122/086). The six Special Illustration Rares are the value layer beneath it:
| Card | Rarity | Why It Is Chased |
|---|---|---|
| Mega Greninja ex | SIR + Mega Hyper Rare | Set mascot and the single biggest pull |
| Mega Floette ex | SIR | The set's antagonist, striking artwork |
| Mega Dragalge ex | SIR | Fan-favourite Kalos Mega debut |
| Cinccino ex | SIR | Standout illustration on a popular Pokémon |
| AZ's Tranquility | SIR (Supporter) | Z-A storyline character card |
| Roxie's Performance | SIR (Supporter) | Character Supporter with crossover appeal |
On secondary markets the English Mega Greninja ex SIR opened near $600 on launch weekend and settled into roughly the $470–505 range within 48 hours. Since then, price trackers have disagreed sharply on where both it and the gold Mega Hyper Rare sit, so treat any single quoted figure with caution and check live sold listings before paying up. Prices move fast on this set.
Pull Rates: What to Expect
The most reliable public data comes from TCGplayer's Authentication Center, drawn from more than 8,500 opened packs. These are community estimates, not official Pokémon figures:
| Pull | Estimated Rate |
|---|---|
| Ultra Rare full art Mega Greninja ex | About 1 in 217 packs |
| Special Illustration Rare Mega Greninja ex | About 1 in 496 packs |
| Mega Hyper Rare Mega Greninja ex (gold) | About 1 in 956 packs |
| At least one SIR in a 36-pack booster box | Roughly a 50-70% chance |
Singles vs sealed
Is It Worth Buying?
Two months after release, it depends on what kind of buyer you are:
Collectors chasing Mega Greninja ex
Buy the singles. The SIR and gold Mega Hyper Rare are rare enough that cracking packs for them specifically is poor value, and tracker prices for both are volatile right now.
Mega Evolution and Z-A fans
Yes. Chaos Rising carries the Kalos storyline forward with strong Mega debuts, and the six SIRs make it one of the better-looking sets in the series so far.
Players
Mega Greninja ex is a genuinely powerful card on paper, 350 HP with built-in damage spread from Mortal Shuriken. Regular ex copies and the English-only Krookodile ex are cheap ways in.
Sealed buyers
Sustained sell-outs two months post-launch suggest demand is real, but buy at sensible retail prices rather than inflated resale. Supply is still arriving in waves.
