5 Times WWE rehashed their own storylines

#2. The Undertaker vs. The Great Khali

The Undertaker's feud against Mark Henry came to an end on an episode of SmackDown, after WrestleMania 22.

As The Phenom prepared to dispose of Henry, a 7-foot giant came strutting to the ring and attacked The Undertaker. The giant was revealed to be the Great Khali, who was discovered by Daivari in the jungles of India, in kayfabe.

The duo battled at Judgment Day, with Khali standing tall in the end. The Undertaker would go on to eliminate Khali in the Royal Rumble match next year. This storyline was an exact copy of Undertaker's rivalry with Giant Gonzalez in 1993.

Taker was in a feud with Kamala in 1992, which ended with a Casket match at Survivor Series 1992. At the Royal Rumble, Giant Gonazlez came out with Harvey Whippleman and attacked The Undertaker, leading to a match at WrestleMania which Taker won by disqualification.

The Undertaker was the only constant in these two storylines, with Daivari replacing Harvey Whippleman, Mark Henry replacing Kamala, and Khali taking in for Gonzalez.
