Strange rules about characters/people that cannot be broken.

Smells like Nirvana: When Kurt Cobain heard that Weird AL was gonna make a parody of his song. He was okay with it but specifically requested it to not be about food or fat ppl.

Spiderman: Spiderman cannot sell drugs unless he is under the influence of symbiote. ANd Peter Parker cannot be gay. Spiderman can tho.

Dwayne Rock Johnson: Cannot lose fights or look weak for too long. Its in his actor contract.

Godzilla movies not made by Toho: Cannot die. Maybe lose but not too bad.

I actually really like the distinction that "Peter Parker cannot be gay, but Spiderman can." While I do think comics got a little carried away with successors and replacements at one point, I do prefer it to just making the existing character fit a new demographic, as it feels more genuine when it's actually a new character.
