#4 CM Punk
Back in 2010, CM Punk was the biggest heel in WWE, leading his apparent "apostles" Serena, Joseph Mercury and Luke Gallows. Through the year, Punk and Rey Mysterio had engaged in an intense rivalry.
The Voice of the Voiceless was intent on Rey Mysterio joining his Straight-Edge Society, and at WrestleMania XXVI, a match between the two was even set with the stipulation that if Mysterio lost, he would have to join the clean-living group.
At the height of the tension between the pair, a Hair vs Straight Edge Society Pledge was booked at No Way Out later that year. After an intense back-and-forth that captivated fans, Mysterio emerged the winner and immediately set to shearing the locks of the loudmouth leader Punk. The WWE Universe was delighted to see the leader of the Straight-Edge Society finally get what he deserved.
After this clash, the pair remained rivals for a short time, taking part in a fatal four-way match for the WWE World Heavyweight Championship, which Mysterio won.
