5 superstars The Undertaker could face if he does not retire

#2 AJ Styles

Talk about a Phenomenal bout

Realistically, if AJ Styles were a WWE superstar back in the day, we would have seen this clash a dozen times. Nonetheless, the match still looks like a genuine possibility with a future WrestleMania clash hanging in the balance.

"The Prince of Phenomenal" vs "The Prince of Darkness" is a marketable feud that could do wonders for WWE. Considering how protean Styles is in the ring, he could carry the Undertaker to a career-defining bout.

The 40-year old Superstar defends his WWE Championship against Shinsuke Nakamura tonight and presuming he loses, Styles could move to Raw for bigger things. "The Phenomenal One" could make the Undertaker look like a million bucks and could deliver an exceptional match with "The Phenom."
