On June 1, 1998, Kane defeated The Undertaker to become the number one contender to Stone Cold Steve Austin’s WWE Championship. Kane defeated Austin at King of the Ring 1998 to become the new WWE Champion only to lose his title the next day.
Kane isn’t the only man on this list who became a world champion for a single day. Currently, Kane is on a hiatus as he serves as the Mayor of Knox County. However, he has graced WWE with his presence wherever they’ve required him to make an appearance.
Kane is one of the longest-tenured employees in WWE today, and he will likely compete in a few more big matches before he calls it a day.
