Hello frens,
As a great opponent of any form of IP, I have been following the event of Disney’s Steamboat Willie entering the public domain with great amusement. The incidents where creators have been falsely demonetized on youtube for rightfully using this film is further underpinned by Disney’s decades-long shameless practices. This article sums it up quite well I think.
That… actually makes a lot of sense? And is what we should want?
Copyrighting The Monkey King in the 16th century (just roll with it, this is going somewhere) made sense. Over time, that copyright would expire.
Fast forward to the 1980s where Akira Toriyama and Shonen Jump basically retold the story but with a lot more robots, werewolves, kaiju fights, and noseless bald cops. Goku is based on The Monkey King but is not The Monkey King and has gone on a much stupider trajectory to become an alien who is too dumb to live and regularly threatens all of existence with his idiocy. And has canonically fucked two babies into his wife without ever kissing her. That is a new character.
As for “change the color of the nose”: (Disclaimer: I am an anime bitch so I am sure this color was already used for Goku as opposed to just Broly but whatever). If you make Goku’s hair Green because he went Super Saiyan Fury Happy Dance Now With The Divine Gods, that is not a new character and the rights-holders for Dragon Ball would rightfully send you a C&D. Whereas, if you make an identical clone of Goku but is evil then you have Turles (or Black Goku (or, honestly, Bardok)) and it can be argued as a new character. Whether a third party could get away with that starts to get incredibly messy and dangerous.
