The Undertaker returned in November at Survivor Series, wearing a "Phantom of the Opera"-like, gray upper-face mask. In the main event of the Royal Rumble in January 1996, The Undertaker was unmasked in a WWF Championship match against Bret Hart, but Diesel interfered during the match, costing The Undertaker the championship. A rematch for the title on the February 5 episode of "Raw" saw similar interference. At that month's In Your House: Rage in the Cage, while Diesel was facing Hart in a steel cage match, The Undertaker delivered a surprise attack, emerging from a hole he had ripped through the ring canvas and dragging Diesel with him down under, allowing Hart the victory. After several weeks of more tit for tat between Diesel and The Undertaker, the feud culminated in a singles match between the two at WrestleMania XII, where Undertaker was victorious.
