In October 2025, a fresh wave of confidential data from Pokémon developer Game Freak surfaced online, renewing discussions around a massive security breach initially dubbed the "Teraleak." This new release of information is a continuation of a significant data leak that first came to light in October 2024.

The original incident involved the theft of nearly a terabyte of data, encompassing over 25 years of the company's history. This initial leak exposed a vast repository of internal files, including source code for multiple Pokémon games, early concept art, internal meeting notes, and the personal information of over 2,600 employees and contractors.

The more recent disclosures from this breach have included detailed information and work-in-progress builds for the upcoming Pokémon Legends: Z-A, the long awaited MULTI-REGION MMO game, and potential plans for the franchise's tenth generation of games.

-Pokémon Wind and Pokémon Waves

Theme: Infinity

Directed by Shigeru Ohmori

-The setting for Pokémon Wind and Waves is: INDONESIA AND SOUTHEAST ASIA!

-Pokémon Wind and Waves start the adventure in a big tourist city, they mention that they specifically wanted to break the pattern of always starting the game on small towns.

-The theme of the game is Infinity:

・Play that continues infinitely

・Land that expands infinitely

・Evolution holding infinite potential

-With Pokémon Wind and Waves Game Freak wants to tackle the jungle environment which really hasn't been fully seen before in Pokémon games.

Survival in the jungle will be one of the main themes

You will be able to beat the game without finishing all the gyms or catching the main legendary, those will be optional (but you need to complete those for the true ending)

- You get the Seed Pokémon at the start of your adventure and you must raise it to a certain level to be able to enter the island for the main legendary

- The island is procedurally generated based on how trained the Seed Pokémon is.

- The evolution for the Seed Pokémon will be procedurally generated, including unique patterns for flowers and fractals, so every player will have a different looking Seed Pokémon evolution.

-The Seed Pokémon will revert to its default form when transferring it to future games or Champions, it will only be procedurally generated inside Wind and Wave

-The player will be able to challenge the final boss right away after getting the ability to traverse the sea, and will be able to defeat it and see the credits.

However it will be a lot more difficult.

-the Gyms and the Titan/Lord Pokémon concepts have been mixed together

- There are in total 18 challenges, one for each type.

- They will be inspired by the Sustainable Development Goals

- Clearing all the 18 challenges allows you to challenge the Champion

Its evolved appearance is said to have infinite variations.

GameFreak goes into the philosophy of the difference between Legends Series vs Mainline New Gens:

The Legend series is about digging deeper.

- Targeted at gamers. Digging deeper into action.

- Digging deeper into the world view and history.

The Main series is about expansion.

- The target is wide, including beginners and fans.

- Furthermore, it promotes the expansion of play through communication.

GAME FREAK IS DEVELOPING A MULTI-REGION POKÉMON REMAKE

The objective is for the protagonist to be able to walk from Sinnoh to Hoenn, will also include Kitakami.

Pokémon Project Seed is not only the dream multi-region Pokémon game that people have always asked for, it also appears to be an MMO.

"Seed is a prototyping project for a next-generation online game playable by multiple people, set in a region that connects Hoenn and Sinnoh"

Set to include: Kanto, Johto, Hoenn, Sinnoh, and Kitakami regions

POKÉMON LEGENDS 3 IS BASED IN GALAR!!!!

Set 1000 years in the past, you must create the first Gigamax Poké Ball with out of control Dynamax and Gigantamax Pokemon to battle. Gameplay appears to be based on Xenoblade Chronicles with concept art that directly references the Xenoblade Chronicles series.

Gameplay is not like the typical Pokémon experience, this game uses a new Formula where a large number of Pokémon will face Bosses.

Players Parties will have a limit of up to 30 Pokémon

Pokémon Legends ZA originally had a new PokeRide system that included using Lucario to jump from building to building.

Leaked video shows an abandoned Splatoon style 4v4 game mode and shooter style gameplay for Pokemon Battles.

The leaks show that buildings were originally more detailed and structured in Pokemon Legends ZA before they were flattened due to performance issues.
