It has been said that the success of the Claremont/Byrne run was born of the conflict-ridden synergy of the two creators, and it is not for nothing that Byrne unlike most of Claremont's other artistic collaborators was officially listed as co-plotter in the credits. And since they were working according to the "Marvel method" Byrne could often add (or at least try to) stuff that Claremont hadn't intended to a story.
