#5 The Deadman gets stuffed in a coffin but vows to return
In 1994, the WWE Championship was held with an iron fist by Yokozuna. In reality a Samoan member of the famous Anoa'i family, which includes the Rock and Nia Jax as well as the Usos, Yokozuna portrayed a Japanese sumo wrestler monster heel.
Undertaker entered into a feud with Yokozuna, which culminated in a casket match at the Royal Rumble 1994. Since it was a casket match, and therefore in Undertaker's wheelhouse, many fans thought that this would finally be the end of Yokozuna's title reign.
However, with the help of a whole gang of heels, Yokozuna managed to shut Taker into his own coffin. But then Undertaker would appear mysteriously on the Titan Tron, vowing he would return.
This was a story line way to give Taker time off to heal a nagging back injury, but it shocked fans at the time because Undertaker was believed to be invincible prior to this match.
