More than 200GB of reportedly leaked Cartoon Network production files have exposed behind-the-scenes animation materials from shows spanning several decades, including The Powerpuff Girls and The Amazing World of Gumball.
According to Mashable, the files were shared through a Google Drive folder, which the publication accessed to independently examine the material.
Other productions reportedly affected include Foster’s Home for Imaginary Friends, The Looney Tunes Show, Duck Dodgers and Garfield.
Anonymous Account Linked to File Sharing
The leak appears to have originated from an anonymous account on X using the name “totallynotaburner”. The account also shared a Google document linking to files associated with other animated productions, including Teen Titans, Dexter’s Laboratory, Robot Chicken and The Grim Adventures of Billy & Mandy.
Many of the links have since been taken down, with some reportedly removed following copyright complaints.
Mashable said Warner Bros. and Paramount did not respond to requests for comment before publication. The source of the files and the circumstances surrounding their release remain unclear.

What Do the Leaked Files Contain?
The material reportedly includes storyboards, pitch documents, character model sheets and digital puppet rigs.
Storyboards map out scenes before animation begins, helping production teams plan movement, framing and visual storytelling. Pitch documents outline concepts developed for proposed shows or episodes.
Character model sheets provide reference drawings that help artists maintain consistent designs across scenes. Digital puppet rigs allow animators to manipulate characters using digital controls, reducing the need to redraw every movement frame by frame.
Together, these materials can reveal how professional animation teams develop characters, plan sequences and build the assets used in finished productions.
Copyright and Animation Preservation Concerns
Although the files offer insight into the animation process, their unauthorised distribution raises concerns about copyright, intellectual property and the protection of artists’ work.
The incident also highlights challenges surrounding the preservation of production archives. Materials from older shows can become difficult to access as studios restructure, production teams change and digital storage systems evolve.
Such archives may contain valuable records of creative decisions and techniques that are not visible in the finished programmes.
Merger Speculation Remains Unverified
The leak emerged shortly after Skydance, led by David Ellison, reportedly completed a $110 billion acquisition of Warner Bros. Discovery on October 6.
The combined company’s entertainment assets include Warner Bros., HBO, DC Studios, Paramount, CBS News and Cartoon Network, among other brands and networks.
Some social media users speculated that Paramount’s security systems could be connected to the incident. However, no evidence cited in the report establishes such a link.
It also remains unclear whether the files were obtained before or after the reported merger, or whether the incident involved any breach of a studio’s internal systems.
For now, the leak has drawn attention to the security of animation production materials and the challenges of protecting creative archives in an increasingly digital industry.
