As Pokemon’s next mainline era approaches, the community is already dissecting what Gen 10 could look like—especially its online ambitions. New leaks for Pokemon Winds and Waves now claim a far larger Pokédex, a wave of regional and battle-focused forms, and MMO-like lobby features, with additional creature reveals tied to a long-running leaker.
What the latest leaks say about the Pokédex and new species
A new batch of information circulating online claims Pokemon Winds and Waves will ship with a Pokédex covering 530 species, including roughly 300 new additions. The same leak set suggests the games will include a Salandit cross-gen evolution that becomes Poison/Dragon, alongside a broader mix of returning and brand-new Pokémon—estimated at about 230 returning species if the “300 new” figure holds.
The context matters: fans reportedly expected fewer leaks for the Gen 10 titles because the Nintendo Switch 2 can’t be datamined. Still, more information is appearing from sources described as reliable by the leak report, and one name in particular—Billy—has been linked to multiple past disclosures.
Billy is said to have leaked ports for Pokemon FireRed and LeafGreen before their announcement, and the same source is now credited with revealing seven new Pokémon. Among those, the most prominent is a three-stage pseudo-Legendary concept resembling a Komodo dragon early on, then developing wings and eventually breathing fire.
Other newly leaked Pokémon concepts include a pirate-themed bird, a tapir, a sniper-styled echidna, and a kangaroo-like Pokémon with boxing themes. The leaks also suggest possible version-exclusive additions tied to sun and moon themes—described as a hornbill-related Pokémon for one version and a rabbit-related Pokémon for the other—though the report frames these as “possibly” exclusive.
Regional evolutions, battle gimmick forms, and where the MMO-lite idea fits
Beyond the raw Pokédex size, the leaks also focus on how Pokémon could change in battle. According to the report, Pokemon Winds and Waves will include special battle forms for Pikachu, Arcanine, Kecleon, and Lucario. The same list is also said to include battle gimmick forms for seven additional Gen 10 Pokémon.
On the regional side, the Salandit evolution is singled out as a key cross-gen change, and the leak report also ties earlier discussions of weather-related mechanics to the idea that some Pokémon may receive weather forms.
Online features are another major pillar of the leak package. The report claims the games will include MMO-like elements for online play, including a lobby structure described in earlier leak information as appearing on the first island and associated with the hotel where players begin their journey.
However, the leaks also suggest that not everything from the earlier MMO talk made it through development. The report claims that procedural generation and a more sweeping MMO approach may have been cut, and that the end result could point to a different kind of Pokemon experience—allegedly centered on the four Japanese regions of Kanto, Johto, Hoenn, and Sinnoh.
Story beats, voice acting, and what fans should watch next
The leak report adds more narrative and production details. It claims the story will revolve around three main plotlines, described as similar to what was seen in Gen 9, and it’s also characterized as “the most personable” to date.
There are also character and presentation notes. The report claims Lt. Surge’s son is included and uses a Raichu that is said to be based on the father’s Pokémon, though it remains unclear whether that Raichu can Mega Evolve.
Voice acting is another sticking point. The leaks suggest voice work was planned for Gen 10, but current builds accessible to leakers may not include it—leaving the community uncertain about whether it’s fully absent or merely incomplete.
Finally, the report indicates that many developers may have already moved on to work on Gen 10’s DLC, implying the core content pipeline may be further along than fans assume. If even a portion of these claims proves accurate, it would mark a clear shift in how aggressively the franchise is experimenting with online structure and battle customization.

Expert View
If these claims hold up, they point to a Gen 10 strategy that’s less about raw novelty alone and more about systems: bigger creature rosters, more ways to alter battles through forms, and an online layer that borrows from MMO social structure. That combination matters for competitive and community play—lobbies and early onboarding can directly influence how quickly players form groups, contest metas, and coordinate events. At the same time, the uncertainty around voice acting and the suggestion that a broader MMO/procedural plan was cut highlight a common reality in big RPG development: early concepts can shrink, but the most visible mechanics often survive in altered form. For the esports-adjacent community, the next signal to watch will be whether the claimed MMO-lite lobby and form-heavy battle mechanics make it into final builds, because those are the elements most likely to shape early tiering and content creation.
