The Undertaker versus Sid Justice
Perhaps no two wrestlers' WrestleMania fates were more radically altered in 1992 than the Undertaker and Sid Justice.
In the summer of 1991, Undertaker was a major heel and would go on to defeat Hulk Hogan to win the WWF Championship (albeit for less than a week) in November. Sid was being groomed as the “next big thing” to potentially replace Hogan was the top babyface in the company.
Could Sid Justice have ended the Undertaker's WrestleMania streak before it even started? Rumors suggested that the early plan was for the two to meet in a match at WrestleMania.
However, due to a variety of circumstances, by early 1992 the Undertaker was a newly turned babyface. Sid had himself turned heel and was set to face off against Hogan at WrestleMania instead.
Furthermore, if the match had happened, Sid would reportedly have been penciled in to get the win. This would have helped to continue his push as the heir apparent to Hogan, but also would have ended “The Streak” of the Undertaker before it even began!
