#2 Ken Shamrock returns
Ken Shamrock is a renowned performer and was considered the most dangerous man during his time in the WWE. The wrestler could fight anyone and raise hell through his work. During his performances, he was always ready to attack his opponents and showed no compassion towards them.
During his time in the WWE, no male wrestler was safe, and when he was asked to fight Chyna on 10th May 1999 episode of Raw, Ken refused to fight, but after being provoked by Triple H, he attacked The Game and laid down Chyna to the mat.
A feud between him and Kurt Angle would be great especially considering that Kurt Angle uses Ken Shamrock's move Ankle Lock, and has taken down a host of wrestlers over the years.
If the two wrestlers agree, a match between the two can happen at Wrestlemania 35.
