The new batch of materials is said to be from an early Generation 10 build Pokemon games appeared online. Leaked content includes decidedly bizarre Pikachu animation, a massive urban metropolis, and possibly the first look at a Gen 10 Pokémon professor, among other things.
Information about Game Freak's Gen 10 titles has been trickling in since October 2024's “Teraleak” which led to many Pokemon the release of internal developer documents online, possibly as a result of a data leak. Subsequent reports suggested that the upcoming games may be named Pokemon wind and wave or Winds and waves.
Pokemon Gen 10 Region Map Leaks Online And There's Too Much Water
Thanks to a well-known leaker with a proven track record, Pokemon fans can get their first look at the upcoming region for Pokemon Gen 10.
More alleged leaks of Pokemon wind and wave materials online
Another batch of alleged Pokemon wind and wave materials appeared in late December 2025 from several sources. Among them is a short animation of a level 30 male Pikachu that has a shiny glow and appears to be pulsing, with its various body parts gradually changing shape. The source of this particular leak described the disturbing creature as “majin Pikachu.” Majin, which literally means “demonic being” or “devilish being”, was previously said to be the codename of Gen 10. Pokemon battle trick game. According to a machine translation of an earlier leak, the mechanic may be associated with some sort of “weather movements”.
Roundup of the latest Gen 10 Pokemon leaks
A much simpler explanation for the bizarre Pikachu leak is that it shows a model and animation test rather than anything that should be part of the Gen 10 games as is. However, the appearance of such an atypical Pikachu may support the former claim Pokemon wind and wave would offer endless variations of selected species. As unconventional as it may seem, the kind of free-form model distortion seen in the late December 2025 leak could potentially be one method for Game Freak to implement such a system.
Pokemon Wind and Wave will reportedly feature at least one massive city
Another image from the recent wave of leaks shows the character exploring what appears to be a large, densely built-up city. While the environments use distant LOD models that were apparently drawn in the early stages of rendering, the graphics are detailed enough to reveal an eclectic mix of architecture, from modern steel and glass skyscrapers to more traditional landmarks, such as a concrete structure with a pagoda-like tower located near the center of the leaked screenshot. Charizard can also be seen in the image. Although the player character only appears as a silhouette, he appears to be riding a scooter-like board, supporting an earlier leak that claimed Gen 10 Pokemon games would include a traversal Rotom Scooter, similar to the Rotom Bike featured in the Gen 8 titles, Sword and shield.
The third image seen in the new wave of leaks is described as showing a Gen 10 Pokemon professor who looks like an older man. Although the illustration is largely a silhouette, it has been augmented with a face repaint, revealing a bushy beard and two equally unruly eyebrows. Just like its predecessors, the new Pokémon professor is expected to guide the protagonist throughout the game's story. He is even said to drive a car in the Gen 10 games.
The latest part of the leak shows an early screenshot of a Pokémon Center set on an idyllic tropical island. Its presence suggests that it could be one of the 15 or so larger islands found here Pokemon wind and wave. The games are expected to feature many other smaller landmasses, with the total number of islands estimated at around 54. Previous leaks have also suggested that procedurally generated islands may be part of the package to complement Game Freak's hand-crafted locations. Generation 10 Pokémon titles are expected to be announced next year on Pokémon Day: February 27, 2026.
