Greninja never had a Mega Evolution in the games, but in March 2026 it got one on cardboard anyway — and unlike most chase Pokemon with a decade of reprints to sort through, Mega Greninja ex has exactly one set to know: M4 “Ninja Spinner.” Four printings, one release date, no earlier era to untangle.
That makes it one of the cleanest complete-set targets in the current Mega ex line. This guide walks through all four M4 printings of メガゲッコウガex (Mega Greninja ex), what the card actually does, and the one mix-up worth clearing up before you buy — a lot of people searching for this card are actually thinking of a different Greninja entirely. We ship Japanese sealed product and singles out of Tokyo every week, so the stock and pricing below come straight from what we’re currently holding.
Mega Greninja ex has exactly four printings, all from M4 “Ninja Spinner” (March 13, 2026): RR, SR, SAR, and MUR — making it a fully completable chase line from a single set. We currently list the PSA10 SR (M4 098/083) at ¥12,587 (update: currently sold out — restock requests via Quick Order) (4 copies listed) and the PSA10 SAR (114/083) at ¥45,402 (update: currently sold out — restock requests via Quick Order) (1 copy listed) — once it sells, it’s gone.
Prices listed are our own currently-listed PSA10 stock in Japanese yen. We don’t quote outside market prices.
Every Mega Greninja ex Printing
All four printings of Mega Greninja ex come from a single set — M4 “Ninja Spinner” — and as of now, all known Mega Greninja ex printings are in M4:
| Printing | Number | Rarity | Our stock |
|---|---|---|---|
| Mega Greninja ex MUR | M4 120/083 | MUR | Not currently in stock |
| Mega Greninja ex SAR | M4 114/083 | SAR | ¥45,402 (PSA10, 1 copy listed) (update: currently sold out — restock requests via Quick Order) |
| Mega Greninja ex SR | M4 098/083 | SR | ¥12,587 (PSA10, 4 copies listed) (update: currently sold out — restock requests via Quick Order) |
| Mega Greninja ex RR | M4 022/083 | RR | Not currently in stock |
The MUR at 120/083 is the numerically last and rarest treatment in the set, the SAR at 114/083 is the alternate-art chase slot, the SR at 098/083 is the standard super rare, and the RR at 022/083 is the base holo version most collectors will pull first out of a booster. Unlike Pokemon that have been reprinted across multiple eras and languages, as of now, every known Mega Greninja card traces back to this exact four-card ladder.
Inside M4 “Ninja Spinner”
M4 “Ninja Spinner” (拡張パック「ニンジャスピナー」) released in Japan on March 13, 2026, with Mega Greninja ex as the cover Pokemon — the official tagline reads 「攻メ続ケロ！メガゲッコウガex参上！」(“Keep attacking! Mega Greninja ex has arrived!”). Packs run ¥180 (tax included) for five random cards, and the set totals 120 species across Normal/R/RR (001–083), AR (084–095), SR (096–113), SAR (114–119), and a single MUR (120).
The set also carries five other SAR chase Pokemon alongside Mega Greninja — Mega Floette ex, Mega Dragalge ex, Cinccino ex, AZ’s Comfort, and Homika’s Performance — so a full box break isn’t a one-hit set, but Mega Greninja is unambiguously the headline card. For the complete set breakdown beyond just the Greninja line, see our M4 Ninja Spinner complete guide, and for pull-rate discussion across the set’s chase slots, our Ninja Spinner pull rates guide.
How Mega Greninja ex Plays
Mega Greninja ex is a Stage 2 Water-type that evolves from Frogadier, carrying 350 HP. Its ability, “Hissatsu Shuriken,” lets you discard a Basic Water Energy from hand once per turn while it’s in the Active Spot to place 6 damage counters on an opposing Pokemon — a slow-burn pressure tool rather than a one-shot attacker.
Its attack is literally named after the set: “Ninja Spinner,” costing [W][W] for 120 damage, with the option to return a Water Energy from itself to hand for an extra 80 damage. As printed on the card, a Mega Greninja ex knockout gives up 3 prize cards instead of the usual one or two, so it’s a high-risk, high-reward Active Spot Pokemon rather than a bench piece.
The SAR at 114/083, illustrated by Susumu Maeya, carries the same text in the set’s full alternate-art treatment — the printing most collectors are chasing for display rather than play.
Don’t Confuse This With Ash-Greninja EX
If you’ve been searching for a “Mega Greninja” card and kept landing on something from the XY era instead, here’s why: no Mega Greninja card was ever printed during the XY era. Greninja simply never had a Mega Evolution in the games at that time, so it never got an “M ___EX” treatment alongside cards like M Rayquaza-EX or M Gardevoir-EX.
The card people are actually thinking of is サトシゲッコウガEX (Ash-Greninja EX), numbered 218/XY-P, a promo distributed through the XY&Z anime tie-in — including an episode-102 viewer giveaway and the Next Generation World Hobby Fair ’16 Winter. It’s a real and well-known card, but it’s built on a different mechanic entirely: Battle Bond, a form change tied to the anime’s story, not a Mega Evolution.
Ash-Greninja EX (218/XY-P) is a Battle Bond form change from 2016. Mega Greninja ex (M4, 2026) is a genuine Mega Evolution ex card and the first one Greninja has ever had. They share a species, not a mechanic — and they’re a decade apart.
If you’re after the full Greninja lineage across every era — Ash-Greninja EX included — our Greninja cards guide covers all of them side by side. This article stays focused on the M4 Mega Greninja ex chase line specifically.
Which Printing Fits Your Budget
With only two of the four printings currently in our stock, the choice is fairly direct:
- ¥12,587 — PSA10 SR (M4 098/083) (update: currently sold out — restock requests via Quick Order). The standard super rare, four copies listed, and the most accessible way to own a graded Mega Greninja ex.
- ¥45,402 — PSA10 SAR (114/083) (update: currently sold out — restock requests via Quick Order). Full alternate art, one copy listed — one-of-one, so once it sells it’s off the shelf.
If you’re building toward the complete four-card ladder, the RR and MUR round out the set but aren’t currently listed here — check back or reach out via our Quick Order page for sourcing. And if Mega Greninja is just one card on a wider budget hunt across the whole Mega ex line, our budget Mega ex cards guide rounds up PSA10 entry points across sets under ¥15,000.
Why This Is the First-Ever Mega Greninja Card
Mega Greninja debuted in the TCG in the MEGA series, which revives Mega Evolution as a card mechanic without being limited to Pokemon that had Megas back in the XY games — several species are getting their first-ever Mega treatment on cardboard through this line, and Greninja is one of them. M4 “Ninja Spinner” is the set that made it happen.
That’s part of what makes the chase clean: there’s no earlier “real” Mega Greninja to compare against, no XY-era original to chase alongside it, and no separate English-language predecessor to sort out. Every Mega Greninja ex card that exists sits inside this one set, at these four rarities.
For where Mega Greninja ex sits against other current-era Mega ex chase cards, our Mega Evolution Pokemon cards chase guide covers the wider line, and our PSA10 Mega Pokemon cards guide breaks down how grading premiums compare across sets.
