Well, of course, sure, all the time to one degree or another. But not quite, in most cases, in the way you make it sound.

Nobody who’s working on a regular Marvel book is simply writing along without their editors knowing at least in the most general sense what it is that they’re going to be writing. So most of these conversations take place well before anybody has started typing anything more than an outline.

And it’s seldom just a case of saying no. You have a conversation about whatever the point is, and either the writer convinces you, or you convince the writer, or you come up with some mutually-agreeable compromise. Or, in an absolute impasse situation, then you maybe have to just say no, and deal with the ramifications of that. But it’s all done hand-in-hand.

It’s also not just creators, but sometimes editors and staff as well who need to be stopped or convinced or swayed. Sometimes an idea takes heat, and in the enthusiasm of the moment, nobody really wants to think it through and assess the cost/benefit ratio. This is the sort of thing that can lead you to situations where Hawkman’s status quo and history are so jumbled that absolutely nobody can make heads or tails of them–so you need to be vigilant about that as well.
