Expert Poll: Who should be The Undertaker's final opponent? 

Mr. Warren Hayes - Fightful

What if the Undertaker ended his career inside the Firefly Fun House?

Warren Hayes is a wrestling podcaster who does not fear the reaper but has apprehensions about American cheese. He records his podcast, the Mr. Warren Hayes Show, live every Thursday evening on his Youtube Channel and he's also a regular contributor on the Fightful podcasts.

While others I've spoken to want to see The Undertaker go out in style with one final in ring spectacular, Warren is looking at the possibility of that just not being likely or even a possibility at this point.

While The Deadman is in better shape now than he was a few years ago, the longer his career goes on the more likely Father Time ultimately wins out. So maybe, a poetic ending at the hands of an old rival might be the best way to end his storied career.

A cinematic masterpiece might be the best way to go out

"If there is anything that the “Last Ride” documentary has taught us about the Undertaker, it’s that Mark Calaway’s body is broken and in pain. It is improbable to believe he could go out in his final match like the Deadman we all once knew. It cannot depend on athletic competition alone. Besides, there is a much more compelling story to be told, if he is put in a Firefly Fun House match.

Taker always said that he would want to go out on his terms, when the moment was right. But what if that moment had already passed? What if it was no longer up to him? What if he is forced to come to the deep realization that he has overstayed his welcome?

Imagine how chilling a Firefly Fun House match could be, as Bray Wyatt confronts him with the most terrifying reality of them all: that the Undertaker we knew has been gone for a while. That his final matches, like his ones against Roman Reigns, losing the WrestleMania streak, and the disastrous Saudi Arabia shows had tainted his career. Bray would confront Taker and eventually expose that the Undertaker’s true enemy, the one that kept him from having his legacy truly capped long ago, was WWE. Vince McMahon himself.

So, instead of fighting to the bitter end one more time, instead of succumbing to Vince’s final whim, Mark Calaway realizes that he will indeed leave on his terms, leaving Vince in a world without the Undertaker, and lays down for the Fiend, passing the torch to Wyatt in a moment both of dreaded self-realization and defiance.

Finally, the Undertaker earns his warrior’s rest."
