Nobody’s legacy is “tarnished” or otherwise damaged by things other people create.
There is a set of IP rights known as moral rights. These rarely come up here in the US and aren’t discussed much because they are quite limited in the US, but they play a more-meaningful role in France, whose legal tradition attaches certain rights to an artist to restrict use of his work (and who cannot give these rights up, regardless of whether he wants to do so or not, and where these rights never expire, even after death). They tend to aim at this sort of “tarnishing” concern.
That’s not to say that I particularly support this class of right, but there are places in the world where it is more-important and is a real thing in law.
I don’t know whether, in France, they would extend as far as to the use of characters.
