#4 Kurt Angle
During the Attitude Era days, Kurt Angle was one of the biggest if not the biggest Superstar of that Era, hence it's not a surprise that many would have loved to see a feud between Angle and The Fiend.
If this feud would have happened, one would have loved to see Angle's character change after coming face to face with The Fiend. He was a heel for most of his time in the 2000s, so maybe after facing The Fiend, he might have turned into a face.
Whatever the case, this match would have been a battle between two wrestlers who know how to put up a masterpiece.
#3 Stone Cold Steve Austin
Imagining a dream feud in the Attitude Era without Steve Austin is criminal. The Fiend vs Steve Austin could have been the biggest heel vs the biggest face match in the early 2000s.
Although the match between them could have been quite slow, the build-up to it would have been absolutely absorbing. Add to it a WWE Championship belt on the line and you have one of the greatest main events ever.
If these two faced each other, the favorite to come out victorious, as always, would have been the Rattlesnake.
