A new rumor around Pokemon Winds and Waves puts a jaw-dropping number on the table. The claim is that Gen 10 will introduce roughly 300 new Pokemon and forms, which would make it the largest single-generation expansion the series has ever done. That figure is big enough to demand skepticism, so here is what is actually being said, how it stacks up against real history, and what Game Freak has genuinely locked in.
Quick answer: The leak from CentroLeaks says Pokemon Winds and Waves will add around 300 new Pokemon and forms, the most of any Pokemon game to date. Game Freak has not confirmed this, and the only officially revealed Gen 10 Pokemon so far are the three starters.
What the 300 Pokemon leak actually claims
The core of the leak is simple. CentroLeaks posted that Winds and Waves will carry the highest number of new Pokemon ever seen in a mainline game, with the number being floated at around 300 new Pokemon or forms. That phrasing matters, because “forms” is doing a lot of work here.
The original tip is credited to another leaker, and CentroLeaks says it independently checked the information with additional sources before passing it along. That extra step is why the rumor has spread wider than a typical one-off post, but it is still a rumor and Game Freak has said nothing.
How 300 compares to every past generation
The Pokemon roster currently sits at 1,025 creatures spread across nine generations. Adding 300 in one release would bring in close to a quarter of everything that already exists, which is why the number is hard to take at face value. For context, no generation has ever cleared 160 new Pokemon.
| Generation | New Pokemon |
|---|---|
| Gen 1 | 151 |
| Gen 2 | 100 |
| Gen 3 | 135 |
| Gen 4 | 107 |
| Gen 5 | 156 |
| Gen 6 | 72 |
| Gen 7 | 88 |
| Gen 8 | 96 |
| Gen 9 | 120 |
Gen 5’s Black and White holds the current record at 156 new Pokemon, while Gen 6’s X and Y sits at the bottom with just 72. Gen 9’s Scarlet and Violet added 120. A 300 count would nearly double the all-time high, a jump the series has never come close to attempting.
Why weather forms could pad the count
The same leak ties the number to a new battle mechanic built around weather. The claim is that certain Pokemon will gain special weather-based forms, described as being in the spirit of Mega Evolutions or Gigantamax. That fits the region’s heavy focus on wind, sea, and natural phenomena.
This is the detail that makes 300 more plausible than it first sounds. If alternate weather forms are counted as separate Pokedex entries, a big chunk of that total could be transformations of existing creatures rather than 300 brand-new species drawn from scratch. A separate rumor about the box legendaries receiving new forms lines up with the same idea.
What Game Freak has officially confirmed
Set against the leak, the confirmed list is short. The only new Gen 10 Pokemon officially shown are the three starters: Browt, Pombon, and Gecqua. Everything past that point is unverified.
Two box legendaries have leaked but are not officially detailed. The Winds legendary is described as a Garuda-like creature, framed as an elder guardian who guides through the power of wind. The Waves legendary is described as a Naga-inspired, mermaid-like figure tied to the force of the seas. Both reportedly judge whether the player is worthy.
Separate riddle-style teasers have also floated seven possible new designs, including a Komodo dragon evolution line, a kickboxing tree kangaroo, a moon rabbit, and a pirate-themed Maleo bird. None of these are confirmed, and they represent only a tiny slice of the alleged 300.
How much to trust this leak
Winds and Waves has a track record that makes its leaks worth watching. Much of what has circulated traces back to the 2024 Game Freak security breach, often called the “Tera Leaks,” and several of those early details later held up. The reveal trailer confirmed the game’s title, its Southeast Asia-inspired archipelago, the underwater map, the Hotel Island hub, and the hoverboard traversal system.
That said, the 300 figure sits in a different category. It is a single number attached to an early rumor, not a mechanic confirmed on screen, and much of the leaked material comes from an early build where features can change. A procedurally generated island idea, for example, was reportedly cut. Treat 300 as the ceiling of speculation until a Pokedex size is officially stated.
Pokemon Winds and Waves is slated to launch on Nintendo Switch 2 in 2027, so there is a long runway before any of this is verified. If even part of the claim holds, Gen 10 would be the most content-heavy Pokemon release yet, but for now the smart move is to keep expectations grounded in the three starters we can actually see.
