Fortnite AI Darth Vader generated profanity and slurs before hotfix
Fortnite deployed an AI-powered Darth Vader character on May 16, 2025, that used a generative voice model based on James Earl Jones. Within hours, players demonstrated the system generating profanity and slurs, prompting Epic Games to issue a hotfix approximately 30 minutes later.
What happened
On May 16, 2025, Epic Games released a Fortnite update featuring an AI-powered Darth Vader character that players could recruit and chat with using voice commands. The AI character used an AI-generated voice based on the late actor James Earl Jones and was powered by Google's Gemini 2.0 Flash language model and ElevenLabs' Flash v2.5 audio model.
Within hours of the patch release, players discovered the AI Darth Vader would generate profanity and slurs when prompted. Streamers including LoserFruit demonstrated the character using the 'F' word and other vulgarity. Epic Games hotfixed the issue approximately 30 minutes after the update went live.
Reported impact
Players were able to generate vulgar and inappropriate language from the AI character, creating content that could expose younger players to profanity despite parental controls being in place.
Index analysis
The AI system failed to filter harmful outputs despite being used in a game that attracts players of all ages. The rapid iteration and deployment of the feature did not include sufficient testing for edge cases involving prompt manipulation to generate profanity.
Governance controls
Epic Games stated that James Earl Jones' family had approved use of his voice for the feature. Parental consent controls were implemented to restrict minors' access to the interactive AI system. The company responded with a hotfix approximately 30 minutes after players demonstrated the profanity generation issue.
