Release Date: May 22, 2026 | Mega Evolution Series Expansion (ME04)
The ninja frog takes center stage — and it's bringing chaos to Lumiose City.
Chaos Rising drops May 22nd as the fourth expansion in the Mega Evolution Series, and it's shaping up to be one of the most dynamic sets of the year. Based on Japan's Ninja Spinner set, this 122-card expansion brings five new Mega Evolution Pokemon ex cards to the table, led by the fan-favorite Mega Greninja ex.
The theme centers on unstable Mega Evolution energy wreaking havoc across Lumiose City — with conflicting forces like Mega Greninja ex and Mega Floette ex battling for control. If you thought Perfect Order was intense, Chaos Rising is about to crank up the pressure even further.
With pre-releases starting May 9th and a Pokemon Center exclusive ETB featuring a metallic Mega Greninja promo, there's plenty to get excited about. Let's break down everything you need to know.
Chaos Rising introduces five new Mega Evolution Pokemon ex cards. Here's what collectors are already targeting:
The ninja frog finally gets its Mega form, and it's the undisputed star of the set. Mega Greninja ex (Card #022/086) is a Water/Dark-type powerhouse that's been one of the most requested Mega Evolutions since the mechanic returned. The special illustration rare version is going to be THE chase card of this expansion. The Pokemon Center exclusive ETB even comes with a metallic Mega Greninja promo — that's how much they're pushing this one.
Mega Floette ex (Card #035/086) serves as the antagonistic cover star, representing the opposing force to Greninja in the set's storyline. This Fairy-type brings support and healing capabilities that could make it a competitive staple. The conflict between Greninja and Floette drives the "Chaos" in Chaos Rising — expect the artwork to reflect this tension beautifully.
Mega Pyroar ex (Card #15) brings Fire-type ferocity to the Mega lineup. Pyroar has always had a loyal following, and its Mega form should deliver the aggressive playstyle Fire-type fans love. Watch for the special illustration rare version to command premium prices.
Mega Dragalge ex (Card #065/086) is the sleeper pick of the set. This Poison/Dragon-type has unique typing that could make it a collector favorite and competitive dark horse. The illustration by 5ban Graphics is already generating buzz among art collectors.
The fifth Mega Evolution Pokemon ex hasn't been officially confirmed, but speculation points heavily toward Mega Gallade ex. We'll update this guide as soon as it's revealed.
Here's what you're working with in Chaos Rising (122 cards total):
| Card Type | Count |
|---|---|
| Mega Evolution Pokemon ex | 5 |
| Pokemon ex (Total) | 10 |
| Illustration Rare Pokemon | 11 |
| Ultra Rare Pokemon & Trainers | 18 |
| Special Illustration Rare | 6 |
| Mega Hyper Rare | 1 |
Note: Chaos Rising is based on Japan's Ninja Spinner set, which means the English version should be a near-exact replica with potentially minor adjustments.
Based on patterns from Perfect Order, Ascended Heroes, and the Ninja Spinner data from Japan, here are the estimated pull rates for Chaos Rising:
| Rarity | Estimated Odds | Per Booster Box (36 packs) |
|---|---|---|
| Illustration Rare | ~1 in 6 packs | ~6 per box |
| Pokemon ex / Ultra Rare | ~1 in 8 packs | ~4-5 per box |
| Special Illustration Rare | ~1 in 30-40 packs | ~1 per box (not guaranteed) |
| Mega Hyper Rare | ~1 in 200+ packs | ~1 per 6 boxes |
Reality check: You're looking at roughly 6 booster boxes (~$800-900) on average to pull a single Mega Hyper Rare. The SIRs are more reasonable but still require some luck. If you're specifically chasing the Mega Greninja ex SIR, the secondary market might be kinder to your wallet once prices stabilize a few weeks after release.
Note: These are estimates based on similar Mega Evolution sets. Official pull rates aren't published by Pokemon Company, so actual results may vary.
Mega Evolution Pokemon ex are the heavy hitters — they evolve from basic Pokemon ex and represent the absolute peak of a Pokemon's power.
This risk-reward dynamic is what makes Mega ex cards so interesting. You're betting big — one KO and you might hand your opponent the match. But play it right, and your opponent won't get that chance.
The set's storyline revolves around unstable Mega Evolution energy — expect some cards to play into this theme mechanically, potentially with effects that trigger when energy becomes "unstable" or with risks that mirror the lore.
