In February 1992, The Undertaker's ally Jake "The Snake" Roberts tried to attack "Macho Man" Randy Savage's manager/wife Miss Elizabeth with a steel chair when Undertaker stopped him, turning face for the first time. The turn was solidified on the February 29 episode of "Superstars", when Roberts confronted The Undertaker on the "Funeral Parlor" set over that incident (aired on "Saturday Night's Main Event XXX"). After demanding to know whose side The Undertaker was on and getting the reply "Not yours!", Roberts attacked both Bearer and The Undertaker, only for Undertaker to stand his ground and run Roberts off. The Undertaker defeated Roberts at WrestleMania VIII. He then feuded extensively with wrestlers managed by Harvey Wippleman throughout 1992 and 1993, such as Kamala and Giant González. Also at this time, he headlined the first episode of "Monday Night Raw" on January 11, 1993, with a victory over Damien Demento. According to Calaway, working with González was "It was survival every night trying to figure out what he could do" and "took years off my career". He faced González at WrestleMania IX, which is notable as Undertaker's only disqualification win at WrestleMania after the use of chloroform. His rivalry with Yokozuna culminated in a WWF Championship casket match for the WWF Championship at the Royal Rumble in January 1994. During the match, Yokozuna sealed The Undertaker in the casket with the assistance of several other villainous Wippleman-managed wrestlers to win the match. The Undertaker appeared from inside the casket on the video screen, representing his spirit, warning that he would return. The Undertaker did not appear in the WWF for seven months after his loss to Yokozuna. In reality, he was given time off to allow a back injury to heal.
