The Undertaker is one of the all-time greats, and he featured heavily in the New Generation Era with a variety of outstanding feuds, and others failed to live up to the hype.

The Undertaker made his legendary debut at Survivor Series 1990 and on his first anniversary in WWE, The Deadman defeated Hulk Hogan for his first WWE Championship at the age of 26. Soon, Undertaker turned babyface and he was a face for the entirety of the New Generation Era spanning from 1993-1997. Undertaker was one of the major stars in the New Generation Era with the likes of Hulk Hogan and Randy Savage no longer a part of the fold by plying their trade in WCW.
