The Unknown from the Glasgow Willy Wonka Experience
The Unknown is like an evil chocolatier who lives in the walls. While the story of Charlie & The Chocolate Factory are copyrighted still (i believe owned by Netflix currently as they bought the rights to all of Roald Dahl's works a few years back)
The Unknown is an original character that was created using AI to write the script for this event. AI creations are not able to be copyrighted. Therefore, its public domain
Final showdown between the Legendary Pink Vacuum Cleaner and the Unknown, from the beloved classic "Kirby: Nightmare in Dream Land" (2002?)
I am so sorry.
