Warner Bros. Discovery has filed a major lawsuit against AI image-generation startup Midjourney, accusing the platform of large-scale copyright infringement tied to some of the studio’s most valuable characters. The complaint claims Midjourney enabled users to create unauthorized images and videos resembling icons such as Batman, Superman, Wonder Woman, Scooby-Doo, and Bugs Bunny—figures that have shaped pop culture and represent core intellectual property for the company.
Filed in a Los Angeles federal court on September 5, 2025, the lawsuit alleges that Midjourney knowingly allowed this content to be produced and profited from it. According to the filing, the startup previously maintained safeguards to prevent such misuse but allegedly removed them in a calculated shift. Court documents reportedly compare AI-generated images with official artwork side by side, asserting that the similarities are striking. Warner Bros. is seeking statutory damages of up to $150,000 per work and an injunction to block further infringement.
This is not an isolated clash. Other major studios, including Universal and Disney, have raised similar concerns in separate actions, arguing that generative AI tools are enabling unauthorized depictions of their characters on a massive scale.
Midjourney’s defense centers on transformative fair use. The company argues that its system does not copy any single image; rather, it learns visual concepts from billions of examples and synthesizes new outputs from that knowledge—much like human artists who study and draw inspiration from existing work. Midjourney also points to its terms of service, which prohibit users from generating infringing content, and contends that individual users bear responsibility for how the tool is used.
The stakes extend far beyond a single courtroom. This case could influence how the legal system defines originality, authorship, and accountability in the era of generative AI—shaping where the line is drawn between inspiration and infringement. As companies, creators, and AI platforms push the boundaries of creativity and technology, the outcome may set important precedents for how intellectual property is protected, how safeguards are enforced, and who is liable when machines mimic the style and substance of beloved characters.
