The Undertaker is a sure fire entrant into the WWE Hall Of Fame whenever he decides to hang up his boots. One of the most enduring characters in wrestling history, the guy has re-invented himself on numerous occasions, keeping the character relevant and ensuring he's serving whatever the company needs at the time. It may seem like an obvious statement, but we'll likely never see another Undertaker come down the line, and wrestling fans will definitely never be taken on another Wrestlemania Streak journey quite like the one we've seen with 'The Deadman'. Up until last year, when Brock Lesnar broke it, the much-vaunted Streak was one of the most impressive stories in wrestling, and even though it's now over, it's still incredible. The list of opponents The Undertaker has faced over the years reads like a who's who of the best in the industry, and there aren't many top names he hasn't held at least one victory over. As sure as his career has been entirely memorable, however, there have been a few moments where his legacy has faltered. As aforementioned, the man behind the gimmick, Mark Calaway, is seemingly willing to do everything he can to enhance the WWE product. A true company man, Calaway's Undertaker has tasted defeat when necessary, whether to shock fans, or to help elevate a new name on the roster. Some of these losses have damaged the mystique of The Undertaker, but which are the 10 worst offenders? WWE hype states you can't kill what is already dead, but these matches didn't do a whole lot for the promotion's own Deadman.
