Doug: It's been a long time since we've had a good, ol' fashioned Versus! Today we're going to ask you about five books that suddenly had a guest-star thrust upon (or within) them. Of the five, which was your favorite, which would be non-favorites, which worked better with the line-up change and which should have been left alone? For your musing, we've provided the last cover under the old title and the subsequent change the following issue. Of course, in all but one case, the new resident had been in, well -- residence for some time prior to the official renaming of the book. Have at it!
