Massive Pokémon leak reveals beta designs, source codes and plans for upcoming titles

Pokémon developer Game Freak has confirmed that there has been a breach when reams of internal materials related to the franchise – from source codes to early and in some cases scrapped character designs – surfaced on social media this weekend. In a statement released Thursday (translated from Japanese), the company said it discovered its servers were hacked in August and that confidential employee information was leaked. The Pokémon leaks were not addressed, although the majority of this content appears to have been published online after the statement was released.

Leaked documents and images flooded in and X began throwing everything away on Saturday afternoon. The “Teraleak” files, as some fans call them, supposedly contain source code for previous games such as: Pokémon HeartGold And SoulSilver, Codenames for the Switch 2 and the upcoming Gen 10 Pokémon Games – “Ounce” and “Gaia” respectively – indicate a development in progress Pokémon MMO and internal discussions from design meetings. There are also details about the supposedly unpublished ones Detective Pikachu Sequel and other planned Pokémon films as well as a new anime series.

The scope of the leak is enormous and, in addition to the source codes, also reveals a lot of beta character designs and concept art. Neither Nintendo nor The Pokemon Company have publicly confirmed the leak yet. Engadget has reached out to us for comment. Game Freak said in its statement that it is strengthening its security, apologized to those affected by the breach and noted that the unauthorized third party accessed the personal information of over 2,600 current and former employees.
