Mega Raichu X and Y Pokemon Cards: What Is Known Before MEGA x MEGA Parade

Mega Raichu X vs Mega Raichu Y: The Official Facts

The pokemon.co.jp page 「メガライチュウＸ」「メガライチュウＹ」を発見！ is the primary source. Both forms are ねずみポケモン (Mouse Pokémon), both are でんき (Electric) type, and each uses its own Mega Stone, which the English Mega Dimension site on legends.pokemon.com states as «These two Mega Evolutions of Raichu each Mega Evolve using a different Mega Stone.»

メガライチュウX — 1.2 m, 38.0 kg

Mega Stone: ライチュウナイトX

メガライチュウY — 1.0 m, 26.0 kg

Mega Stone: ライチュウナイトY

The Japanese page adds the detail behind each description. Mega Raichu X generates an electromagnetic field from its two tails and rides the repelling force to float and move; a thick layer of subcutaneous fat lets it sustain high-output electricity for a long time and gives it high defence. Mega Raichu Y is the short-decisive-battle form: its cheek sacs are powered up, the current it generates is amplified as it passes through the head and tail, and the page describes its temperament as rough and combative. Those two paragraphs are the full official character of the pair, and every card detail beyond them is not confirmed.

How Mega Evolution ex Cards Have Been Printed So Far

Without a Raichu card to describe, the closest official reference is the way the MEGA series has printed other Mega Evolutions. The pattern since the first MEGA expansions in 2025 is a Mega Evolution Pokémon ex in the main set as a Double Rare, with a Super Rare, a Special Art Rare and a Mega Ultra Rare version in the secret-rare block, and in the high class pack a further Mega Attack Rare version. The four cards shown for the Parade set follow exactly that path: Mega Greninja ex, Mega Zygarde ex, Mega Darkrai ex and Mega Rayquaza ex each already hold RR, SR, SAR and MUR prints in the official database, and the August 31 renders add an MA version of each.

MEGA Dream ex, the November 28, 2025 high class pack, is the clearest precedent for a Mega Evolution that debuted in the game before it reached the card game: the pack’s ten Mega Attack Rares and its 17 Special Art Rares were all Mega Evolution ex cards that had appeared in the preceding expansions. Mega Raichu X and Y are different in one respect — they have no earlier card to re-illustrate — so whether they arrive as new main-set cards, as secret rares, or both is not confirmed. The Mega Evolution ex rule box used across the series (three Prize cards when Knocked Out) is the mechanic a buyer can expect only if the cards are printed as Pokémon ex.

For the full official picture of the 2025 pack, see our MEGA Dream ex complete guide; for the four Parade cards shown so far, the Mega Attack Rare guide.

Raichu PSA 10 Listings from Tokyo

Collectors who want Raichu in graded form before the Parade set have a back-order route for the modern prints. Each row below is offered as a PSA 10 back order — sourced to order; the product page shows the current terms — and the route is explained on our PSA 10 back order page.

The one physical slab in the Raichu line is the tag-team card: a PSA 10 Raichu & Alolan Raichu GX SR 057/054 Special Art is currently listed at ¥183,155 (~$1,189), the top of Raichu’s modern print ladder and a reminder that Raichu’s rare prints have reached large-card prices before any Mega version existed.

The Circulating Mega Raichu X Card Image

A gold-foil «メガライチュウX» card image has been shared widely on X: HP 370, an ability named メガエレキブースト, an attack メガボルトストリーム for 330, an illustrator credit to 5ban Graphics, and the number 250/193 under the code m2a with a 2025 copyright line. The number is the tell. In the official MEGA Dream ex (M2a) card list, 250/193 is Mega Dragonite ex MUR, the single Mega Ultra Rare of that set, and M2a is the 2025 pack’s code. The image is a fan-made mock-up, and nothing on it should be read as a Parade reveal.

The same check works for the gold box and pack renders and the pack mock-up that places Mega Raichu beside Mewtwo and Charizard: each prints either the M2a code, a 2024 copyright line or 「第2弾」 copy reused from an older product. Our leaked images vs official article shows all of them with the identifying detail. The separate single-form guides, Mega Raichu X and Mega Raichu Y, follow each form on its own.
