We tend to do stories, not fights–we’re not especially concerned with statistics in the same manner as many of our fans. So in most cases, you’d work out a story that was palatable to all parties, and if there was a fight of this sort, the creators and editors/approvers involved would discuss the matter and come to a consensus. It’s not different than when you’d do, say, a Thor vs Hulk fight, except that there are a few more people involved in the discussion.
