#1: The Undertaker stepped out of his mystical persona and revealed a tombstone for AJ Styles
At this point, it is evident that The Undertaker has to maintain this change in character even after his feud with AJ Styles concludes.
AJ Styles has lifted the veil over The Deadman's persona like no other Superstar in WWE history. Furthermore, The Undertaker stepped out of his mystical presence and took a grounded approach to his character this week.
The Undertaker referred to his WrestleMania opponent as Allen Jones, since we're being "real" now. Apparently, things escalated to a whole new level when Styles dragged Michelle McCool (Undertaker's wife) into this feud.
The Undertaker made comparisons to The Phenomenal One's Styles Clash and Michelle's Faith Breaker maneuver, and perhaps that is the real reason why 'Taker's wife was mentioned by Styles in the first place.
Additionally, The Undertaker also invited Styles to bring along Gallows & Anderson to their Boneyard Battle, where they would feel the wrath of the "Unholy Trinity".
After revealing a tombstone with The Phenomenal One's name on it, The Undertaker's go-home promo was exactly what this feud needed a few days before WrestleMania weekend gets underway.
