Massive Pokémon Leak Reveals Beta Designs, Source Code, and Plans for Future Titles.

Game Freak, the developer behind Pokémon, has confirmed that it has suffered a security breach, which has led to the dissemination of a large amount of internal materials related to the franchise, including source codes and character designs that in some cases were never used. In a statement issued on Thursday, the company, which made the announcement in Japanese, revealed that it discovered the hacking of its servers in August, which also resulted in the leaking of sensitive information about its employees. However, direct details about the Pokémon leaks were not addressed, even though much of the content appeared online following the publication of the statement.

The leaked documents and images flooded Reddit and X platforms after Centro Leaks began releasing them on Saturday afternoon. Some fans refer to these leaks as the "Teraleak" documents, which supposedly include source codes from previous games, such as Pokémon HeartGold and SoulSilver, codenames for the Switch 2, and the upcoming Generation 10 Pokémon games, known as "Ounce" and "Gaia," respectively. Additionally, references to a developing Pokémon MMO are revealed, along with internal discussions from design meetings. There is also information about a supposed unreleased sequel to Detective Pikachu and other Pokémon movie projects, as well as a new anime series.

The scope of this leak is considerable, revealing a vast amount of beta character designs and concept art, not to mention the source codes. So far, neither Nintendo nor The Pokémon Company has publicly acknowledged this leak, although Engadget has sought comments on the matter. In its statement, Game Freak expressed that it is strengthening its security measures and apologized to those affected by the breach, emphasizing that the personal information of over 2,600 current and former employees was accessed without authorization.
