#1 WrestleMania 17 revisited

When the American Badass version of The Undertaker’s character debuted in 2000, he did so to confront Triple H. Moreover, one of The Phenom’s most memorable matches while working that gimmick was opposite The Game at WrestleMania 17.
It wouldn’t necessarily be the most natural fit for The Undertaker to return to confront Triple H while The Game is pretty clearly working as a face opposite Batista. Though the Big Evil version of The Phenom did work heel, he would be guaranteed a face pop for a surprise return in his biker visage. Just the same, The Dead Man does have an issue with The Cerebral Assassin going back to the fall and their matches at Super Show-Down and Crown Jewel. Neither man looked his best in those outings, and most fans would probably just as soon call that feud over. Nonetheless, we could conceivably see The Undertaker, as a biker, coming back to confront his old rival one more time.
