#5 After ten years, HBK returns and ends The Undertaker's career at WrestleMania 35
The Undertaker's rivalry with Shawn Michaels is possibly the most intriguing feud in the history of sports entertainment, and might never be replicated again.
Two superstars sharing equitable amount of respect and adulation for each other despite doing everything in their power to end each other's career.
HBK shares a tremendous chemistry with The Phenom and could legitimately dismantle The Undertaker's career next year at WrestleMania 35.
Judging by how their recent confrontation ended, the company were successful in teasing a breath-taking feud to culminate The Show of Shows next year at MetLife Stadium.
If something of this stature happens, then it would be a great way to end The Phenom's career and allow him to close the curtain on a phenomenal career.
