5 Matches The Undertaker could have had at WrestleMania 38 if he wasn't retired 

#4 The Undertaker vs. 'The Demon' Finn Balor

The Undertaker channels the powers of darkness to dominate his opponents. Finn Balor can also tap into the dark side and become 'The Demon King', someone who operates at a whole different level compared to regular Finn Balor.

The two forces of darkness could have had a fantastic collision at WrestleMania 38. It could have been a great passing of the torch, so to speak, between WWE's foremost supernatural forces.

#3 The Undertaker vs. Roman Reigns

Hey, The Undertaker and Roman Reigns already faced each other and it wasn't a good match at all. True, but at the same time, it was the old version of Roman Reigns and not The Tribal Chief, a despicable character we know, love, and dread so much.

With Paul Heyman by his side, Roman Reigns and The Undertaker could have told a fantastic story. The story of an egomaniac, a megalomaniac who's dispatched everyone in his way. But someone from the past who has a score to settle with him has returned to take him down!
