Side by side: left, a original pencil sketch. Right, someone who sent me an AI 'finished' version derivation of it...

As a webcomic author, releasing my work under free culture license, making my art with only Free Libre and Open Source software, and with popular stories and art, I'm facing a new license problem.

The Creative Commons licenses I used since more than a decade (CC By for Pepper&Carrot, and CC By-Sa for MiniFantasyTheater) miss an option: the possibility to prohibit AI generated derivation.

I'm speaking here about AI generated images or texts inspired directly by my creation, characters, lore, or stories. That's because nowadays, you can prompt any AI/LLMs for a Pepper&Carrot fan-fiction, and it will just output something really detailed, knowing the characters, their magic, and their way to speak. Everything about my stories, comics and art were trained.
