10 WWE Wrestlers The Undertaker Faced Only Once
6. Ken Shamrock
Ken Shamrock was another integral part of the Attitude Era and yet another individual who maybe didn't reach the heights that many believed he was capable of reaching. Shamrock was hugely over as a wild card babyface fighting machine, and then equally as over as a corporate henchman.
Shamrock's only televised one-on-one match with The Undertaker was the semi-main event of Backlash 1999, the very first Backlash event in history. 'Taker was feuding with The Corporation at the time, with his sights firmly set on Stephanie McMahon. He had vanquished The Big Boss Man at WrestleMania XV, and Shamrock was in his way at Backlash.
Shamrock was something of a trailblazer when it came to incorporating submissions and MMA into pro wrestling, and he brought plenty of that to the table in this match. It wasn't enough however, as 'Taker picked up the win after interference from Bradshaw.
