Mega Greninja takes center stage

📌 TL;DR: Mega Greninja ex is the first-ever Mega Evolution for Greninja in the TCG, marking new territory for a fan-favorite that has appeared across GX, TAG TEAM, and ex variants since 2014. The set ties into Pokemon Legends: Z-A with Lumiose City locations and brings back the Kalos starters after over a decade.

Greninja has been a fan favorite since its 2014 XY expansion debut, appearing on numerous high-value cards including GX, TAG TEAM, and ex variants. Now, over a decade later, it receives the Mega Evolution treatment as the mascot of Ninja Spinner — a completely new milestone for the character.

Why Mega Greninja matters

• First Mega Greninja Ever: This is entirely new territory for the character, making it an instant collectible for Greninja fans and Water/Dark-type collectors
• Legends Z-A Tie-In: The set features locations from Pokemon Legends: Z-A, specifically Lumiose City, connecting the TCG directly to the upcoming game release
• Kalos Nostalgia: Chespin makes its first set appearance in 11 years, alongside the return of other Kalos starters — a significant callback to the Generation VI era

Set details and structure

📌 TL;DR: Standard Japanese MEGA Expansion Pack (M4) with 120 cards (83 + 37 secret rares). 5 cards per pack, 30 packs per box. Follows Nihil Zero (January 23) as the fourth mainline Mega Evolution era set.

Ninja Spinner (M4) follows the established MEGA Expansion Pack format, continuing the structure set by previous expansions in the series.

Set Specifications

The Spinner mechanic

📌 TL;DR: There is no spinner mechanic. Before release we guessed that the name hinted at randomized, spin-based attacks; the released set has none.

Before release, we guessed that the "Spinner" name pointed to a randomized gameplay mechanic. The set as released has no such mechanic: the name is part of the ninja theme built around Mega Greninja ex. Mega Greninja ex itself is a Stage 2 Water Pokémon with 350 HP and the Ability Mortal Shuriken (details in our Chaos Rising market watch).

Community reactions

📌 TL;DR: Mixed early reactions — excitement for Kalos starter returns and Mega Greninja, and English collectors debate the Chaos Rising vs. Ninja Spinner naming.

Early reactions on Reddit and social media reveal a split community response:

• Positive: Fans are thrilled to see Chespin and the Kalos starters return after over a decade, with Mega Greninja generating significant hype as a first-ever card
• Naming Debate: English collectors wish the international version retained "Ninja Spinner" instead of "Chaos Rising," feeling the ninja theme is more compelling

Expected chase cards

📌 TL;DR: Based on previous Mega series sets, expect Mega Greninja ex in MUR (Mega Ultra Rare) and SAR (Special Illustration Rare) variants as primary chase cards, alongside Trainer SARs and Illustration Rares featuring Kalos Pokemon.

Based on previous Mega series sets like Nihil Zero and Mega Dream ex, expect the following high-value cards:

Prices in Japanese Yen. Values are early estimates based on comparable chase cards from previous Mega series sets. Update, November 3, 2026: on TCGplayer the Mega Greninja ex Mega Hyper Rare (120/083) trades at $401.86 and the Special Illustration Rare (114/083) at $206.40.

Trainer SARs will likely feature Kalos gym leaders or Team Flare members, while Illustration Rares should showcase Chespin, Froakie, and other Kalos Pokemon in premium art treatments.

English adaptation: Chaos Rising

📌 TL;DR: Ninja Spinner's content will be integrated into Chaos Rising, releasing May 22, 2026 internationally. Chaos Rising follows the Ninja Spinner card list, giving collectors two windows to chase Mega Greninja.

For international collectors, Ninja Spinner's content will be integrated into Chaos Rising, released on May 22, 2026. It follows the Ninja Spinner card list: 122 cards in English against 120 in Japanese.

This means collectors have two opportunities to chase Mega Greninja: the Japanese release (March 13) for early access and exclusivity, or the English version (May 22) for wider availability and competitive legality in Western tournaments.
