Do u think the cycle of characters revived is a product of the system employed to create comics? I am unsure how the author is contracted, but it seems very rare that new stories, like, entirely new ones are created. Unlke Japan manga in which authors would begin new stories once their previous one is finished. It seems comic authors have less agency in creating stories than manga artists, so they just recycle everything to make the story continue ?

That’s a great question! I have to admit, I don’t know the business side of manga at all, but I think you’re on to something. 

Historically speaking, U.S comics were created on a “work for hire” basis in which creators are considered employees, and it’s the employer who has the copyright on their product – hence why titans of the field like Jerry Siegel and Joe Shuster (the creators of Superman), Bill Finger (co-creator of Batman), and Jack Kirby (the creator of Marvel, pretty much) got no residuals and had no control over their creations. 

This distribution of rights creates a tendency for the employer to avoid permanently getting rid of an intellectual property which they have the rights to as long as the property is still viewed as valuable. 

From a quick google search, it seems like the legal situation is very different in Japan, where it seems like the copyright is shared between the creator and the publisher. This obviously would give the creator much more leverage over how the story is structured than in the American context.
