Undertaker Debut

The Undertaker had instant credibility when debuting for WWE in 1990. Ted DiBiase hyped up a mystery partner for his Survivor Series team. Undertaker was the big reveal as a heel working with some of the most hate wrestlers on the roster.

Every heel wrestler had the dream of winning the WWE Championship from Hulk Hogan in the early '90s. It would both give them the biggest prize in the industry and defeat the biggest star to win the title. Undertaker accomplished this goal with a shocking victory over Hogan.

The title win came at Survivor Series 1991 and created a moment fans of the era will never forget.

Regardless, the win itself for Undertaker was huge for the heel portion of his career.

2 Face: Best matches in the 2000s
