#4 Shawn Michaels
After a long stint in the tag team division alongside Marty Jannetty, Shawn Michaels turned heel by attacking his partner on Brutus Beefcake's Barber Shop talk show. This moment kicked off one of the greatest singles runs in WWE history, as Michaels was soon elevated to the main event scene.
He won two successive Royal Rumble matches in 1995 and 1996 and went on to win several World titles. Michaels' stint with Triple H in DX was a huge hit among the WWE fans during the Attitude Era. Following his WrestleMania 14 match against Steve Austin, Michaels went on a four-year break.
When Michaels returned in 2002, it seemed like he hadn't lost his touch one bit. His return match against Triple H at SummerSlam was an instant classic, and Michaels never looked back again.
He went on to have many more classics at WrestleMania, earning himself the moniker of "Mr. WrestleMania". Around a decade ago, WWE dubbed Michaels as the greatest WWE Superstar in history, and many would agree with it if they take a look at his accomplishments.
