In terms of endless continuity, there’s always something new coming up. Obviously I want to tell my definitive Batman or X-Men story – which has a beginning, middle, and end – but comics will run for hundreds of years with hundreds of characters. My stories are in a long chain of other writers’ definitive stories. So when it’s time I leave, I’ll try to leave the toys exactly as I found them. So I like to put the characters through changes, but I try to leave a blank slate for the next writer. It’s the nature of the beast. With the big franchises like Batman, Batman always must be Bruce Wayne, in his mid-30s or late 30s, and he always must have a Batmobile and a butler. I can take them to the edge, but it always will come back to the basics. Unlike novel characters, comic book characters last an eternity.
