A fair Q, but, ironically given the choice of examples, it involves Disney characters. 100% guarantee to get a "oh hell no", if asked.
And here is a good distinction to make for Disney and why they are particularly so hard on protecting the artwork.
Most of the older Disney feature films, they don't actually own the copyright for the stories or characters, they only hold copyright on the actual artwork, the visual images, because those films are all based on much older stories that are public domain.
Cinderella, Beauty and the Beast, Snow White, Sleeping Beauty, and the rest of the fairy tail movies are stories that are centuries old and in the public domain.
Alice and Wonderland is an 1895 book that is long off copyright, the story and characters were never owned by Disney, all they own is the artwork for their animated film version.
The Lion King was their first truly original animated feature film to which they own the full rights.
So it matters very much which Disney characters/stories you used.
