Cartoon Network production files leak online days after Skydance merger

A large collection of behind-the-scenes production material from Cartoon Network has leaked online, exposing internal documents and working files from decades of animation history. The leak, which reportedly totals more than 200GB, surfaced just days after Skydance completed its acquisition of Warner Bros. Discovery on Oct. 6, 2026.

Scope of the Leak

The breach centers on a Google Drive folder containing production assets from numerous series, including The Amazing World of Gumball, Foster’s Home for Imaginary Friends, The Powerpuff Girls, The Looney Tunes Show, Duck Dodgers, and Garfield. Mashable independently confirmed access to the Drive folder. Additional material linked via a master Google Doc included files for Teen Titans, Dexter’s Laboratory, Robot Chicken, and The Grim Adventures of Billy & Mandy.

According to IndiaTimes, the total volume of leaked material exceeds 200GB. The files include storyboards, animatics, character model sheets, production guides, and editable animation assets. Specific technical details reveal that many character files are in EPS format, a vector graphics standard that allows art to scale without loss of quality. The leak also contains digital puppet rigs, which are digital versions of characters broken into movable parts for software animation.

Attribution and Response

The leak appears to trace back to an anonymous X account named "totallynotaburner." According to Mashable, the account is based in the U.S. and was created in October 2026. Mashable reached out to the account but did not receive a response. Warner Bros. and Paramount have not responded to requests for comment regarding the authenticity of the leak.

Copyright strikes have been issued against links to the Drive folder and associated Google Docs as they spread. Google removed the original master document linking to the files. While some users on X claimed that raw Flash animation source files, Photoshop files, and fonts were also leaked, these claims have not been independently verified by the reporting outlets.

Context and Security Concerns

The timing of the leak has drawn attention due to the recent corporate restructuring. On Oct. 6, Skydance, led by David Ellison, finalized its roughly $110 billion acquisition of Warner Bros. Discovery. The combined entity, also named Skydance, now controls Warner Bros., HBO, DC Studios, CNN, Paramount, CBS News, and Cartoon Network.

While social media speculation has linked the leak to Paramount’s security infrastructure, there is no evidence currently tying this specific breach to Paramount’s systems. In a separate incident in April 2026, clips and the full movie Avatar: Aang, The Last Airbender leaked online. Variety reported that Paramount’s initial investigation into that incident found the leak did not originate from within the studio. Similarly, Cartoon Brew noted that the public circulation of an archive does not, by itself, establish a recent breach of the company’s systems.

Why it matters

This leak exposes the labor-intensive processes behind professional animation, offering a rare look at materials typically reserved for official art books or studio exhibits. However, the unauthorized distribution raises significant concerns regarding intellectual property and artist rights. As noted by Cartoon Brew, artists should have a say in how studios present their working material, and the leak represents years of unpaid-for access to creative work. The incident highlights ongoing vulnerabilities in media archives, particularly during periods of corporate transition and merger.
