Pokémon Winds & Waves Leak Claims Pikachu and Arcanine Could Get New Forms - What Could This Mean for the TCG?

Pokémon fans may have another major Generation 10 development to watch.

A new wave of alleged Pokémon Winds and Pokémon Waves leaks claims that several familiar Pokémon - including Pikachu, Arcanine, Lucario and Kecleon — could receive special forms connected to the games’ reported weather-based mechanics.

For collectors, Pikachu immediately makes this more than just another video game rumour.

If the leak proves accurate, new forms or battle transformations for one of the most collectible Pokémon in the entire franchise could eventually create fresh possibilities for future Pokémon TCG cards, promotional releases and set themes.

However, there is an important distinction to make from the beginning:

Pokémon Winds and Pokémon Waves are official. These alleged new forms are not.

Here is what we currently know, what remains rumour, and why Pokémon TCG collectors may want to keep an eye on this story.

Pokémon Winds and Pokémon Waves Are Officially Coming in 2027

The Pokémon Company has officially announced Pokémon Winds and Pokémon Waves as new entries in the Pokémon video game series.

The games are scheduled for a simultaneous worldwide release in 2027 and will be released exclusively for Nintendo Switch 2.

The official reveal has already introduced the main characters and a special Pikachu connected to the upcoming games, confirming that Pikachu will have a notable presence in the new generation.

That official foundation matters because it separates the current story into two very different categories:

Confirmed: Pokémon Winds and Pokémon Waves are real and coming in 2027.

Unconfirmed: The latest claims surrounding additional weather-related forms, evolutions and other leaked Pokédex details.

Collectors should treat the second category as speculation until The Pokémon Company or another official source confirms it.

What Does the Latest Pokémon Winds & Waves Leak Claim?

According to recent reports circulating around the Pokémon leak community, several existing Pokémon may be associated with placeholder special weather forms in the upcoming games.

The names reportedly include:

• Pikachu
• Arcanine
• Lucario
• Kecleon
• Seven new Generation 10 Pokémon

Some reports have described these as new “evolutions,” while others refer to them more cautiously as special weather forms or temporary battle-related transformations.

That difference is extremely important.

At this stage, there is no official confirmation that Pikachu is receiving a permanent new evolution after Raichu, nor that Arcanine is gaining a conventional third evolutionary stage.

The safer interpretation is that the leaked information may point towards a new mechanic in which certain Pokémon can change form under specific weather or battle conditions.

Until official information is released, claims of completely new permanent evolutions should be treated cautiously.

Could Pikachu Really Get a New Form?

Pikachu is the biggest name attached to the reported leak, and for obvious reasons.

As the global mascot of the Pokémon franchise, Pikachu has appeared across countless games, promotional campaigns and Pokémon TCG products. Even relatively small changes to Pikachu can become significant from a collector perspective.

Pokémon Winds and Pokémon Waves already have an officially revealed special Pikachu, so the idea that Pikachu may play a larger role in the new generation is not entirely unexpected.

However, the leaked weather-form claims appear to go beyond what has officially been shown so far.

If accurate, this could potentially give Pikachu another distinct design associated with Generation 10.

For Pokémon TCG collectors, that is where things become particularly interesting.

Why Arcanine Is Another Major Name to Watch

Arcanine may not have Pikachu’s mascot status, but it remains one of the most recognisable and popular Pokémon from the original Generation 1 lineup.

The evolutionary family has remained relatively straightforward for decades:

Growlithe → Arcanine

Pokémon Legends: Arceus later introduced Hisuian Growlithe and Hisuian Arcanine, showing that The Pokémon Company is willing to revisit the family with new regional interpretations.

A completely new Arcanine-related form or transformation in Pokémon Winds and Pokémon Waves would therefore be notable — particularly for long-time collectors who have followed the franchise since the original Kanto era.

Once again, though, the exact nature of the alleged change remains unclear.

It may be a permanent evolution.

It may be a weather-based form.

It may be a temporary battle transformation.

Or the leaked placeholder information may change before the final 2027 release.

What Is the Rumoured Weather Mechanic?

One of the more interesting parts of the current leak cycle is the suggestion that weather could play a much larger role in Pokémon Winds and Pokémon Waves.

Pokémon games have used weather for years through conditions such as:

• Harsh sunlight
• Rain
• Sandstorms
• Snow
• Other environment-linked battle effects

But the latest reports suggest Generation 10 may potentially take this concept further, with certain Pokémon receiving special forms or transformations linked to weather conditions.

If true, this could represent a new signature mechanic for the generation.

That would also explain why established Pokémon such as Pikachu, Arcanine, Lucario and Kecleon are reportedly appearing alongside new Generation 10 species in placeholder data associated with special forms.

Still, none of this should be treated as confirmed gameplay information yet.

The Bigger Leak: Could Generation 10 Add Around 300 New Pokémon and Forms?

The Pikachu and Arcanine claims are part of a much larger wave of alleged Pokémon Winds and Pokémon Waves information.

Separate recent reports claim that a leaked build may contain 531 Pokédex slots, with more than 300 placeholder entries potentially associated with new Pokémon or forms.

This has led to speculation that Generation 10 could introduce an unusually large amount of new content.

However, collectors should be careful with the headline number.

“300 new Pokémon” does not necessarily mean 300 completely original species.

Depending on how the game structures its internal data, the number could potentially include:

• Brand-new Pokémon species
• New evolutions
• Regional variants
• Special forms
• Weather-related transformations
• Other mechanic-specific designs

The final number may also change during development.

Even with those caveats, the scale of the reported placeholder data has made this one of the most closely watched Pokémon leak stories surrounding Generation 10.

What Could This Mean for the Pokémon TCG?

This is the biggest question for collectors.

At the moment, no Pokémon TCG set featuring these alleged weather forms has been announced.

There is also no guarantee that every new video game form will immediately receive a major chase card.

However, history shows that major developments from the Pokémon video games frequently influence future TCG eras.

New generations introduce new Pokémon.

Regional forms become new cards.

Major battle mechanics can shape entire TCG blocks and product cycles.

Popular characters and newly introduced forms can eventually appear as:

• Illustration Rares
• Special Illustration Rares
• Promotional cards
• ex Pokémon (or equivalent)
• Mechanic-focused cards
• Collection box promos
• Japanese campaign exclusives
• Special set highlights

That is why the reported Pikachu form is particularly interesting.

If Generation 10 introduces a genuinely new and visually distinct Pikachu transformation, it would be surprising if The Pokémon Company never explored that design in the TCG.

The timing is also worth watching.

Pokémon Winds and Pokémon Waves are scheduled for 2027, meaning their new Pokémon, characters and mechanics could potentially influence the Pokémon TCG releases that follow the games’ launch.

For now, however, that remains speculation rather than a confirmed TCG roadmap.

Why TCG Collectors Should Pay Attention Before Any Cards Are Announced

For collectors, major Pokémon TCG trends do not always begin with a booster box announcement.

They often begin earlier.

A new Pokémon is revealed in a game.

A character becomes unexpectedly popular.

A new regional form attracts fan attention.

A battle mechanic becomes the identity of a generation.

Only later do those developments begin appearing across cards, promos and sealed products.

This is why Pokémon Winds and Pokémon Waves matter to the TCG community even before a dedicated Generation 10 card set exists.

The games could establish the Pokémon, designs and mechanics that shape a future era of the Pokémon TCG.

And if Pikachu is genuinely receiving another major form, collectors will almost certainly be watching closely.

Our View: Exciting, but Do Not Treat the Leak as Confirmed

The current Pokémon Winds and Pokémon Waves leak cycle is fascinating, particularly because it involves major established Pokémon such as Pikachu and Arcanine.

But the distinction between official information and reported leak material is essential.

What we know officially:

• Pokémon Winds and Pokémon Waves are real.
• The games are coming worldwide in 2027.
• They are being released for Nintendo Switch 2.
• A special Pikachu has already been officially shown.

What remains unconfirmed:

• Pikachu receiving an additional weather-based form.
• Arcanine receiving a new form or evolution.
• Lucario and Kecleon receiving weather forms.
• The exact mechanics behind the reported transformations.
• Claims surrounding roughly 300 new Pokémon, forms or placeholder entries.
• Any future Pokémon TCG cards based on these alleged designs.

Until official announcements arrive, collectors should treat the leaked details as interesting possibilities rather than confirmed facts.

Final Thoughts

Pokémon Winds and Pokémon Waves may still be some time away, but Generation 10 is already shaping up to be an important chapter for the wider Pokémon franchise.

If the latest leaks are accurate, the games could introduce a major weather-based mechanic alongside an unusually large number of new Pokémon, forms and evolutions.

The possibility of new designs for Pikachu and Arcanine is particularly significant.

For video game fans, it could mean a major change to two iconic Pokémon.

For TCG collectors, it raises a different question:

Could these designs eventually become part of a future Pokémon TCG era?

There is no confirmed answer yet.

But with Pokémon Winds and Pokémon Waves officially scheduled for 2027, this is a development worth watching closely.

Sawadeekard will continue tracking major Pokémon Winds and Pokémon Waves announcements — particularly developments that could affect future Pokémon TCG sets, promotional cards and collector releases.
