 During seasons 6 and 7, the ones that took place on the UPN network, the  final shot of the opening credits shows Sarah Michelle Gellar, as in all  the previous seasons. The difference is that rather than those images being  that of Buffy, they were of facsimiles of the Buffy character. For the  majority of Season 6 the final image of the opening credits was of the  Buffy Bot shortly before Glory ripped its head off and Season 7s image was  of the First Evil, pretending to be Buffy while manipulating Spike. For  some fans this plays to the idea that Buffy was somehow not the same after  having been resurrected at the beginning of Season 6 through the end of the  series run.
