5 Shocking WWE Post-PPV Raw Returns

#1 Sting (Raw after Summerslam 2015):

Sting made an Unexpected return on the Raw after Summerslam 2015.

If there is one Superstar we would have never expected to see in a WWE ring, it has got to be The Stinger. Prior to 2014, Sting did everything in his power to avoid signing with WWE. He was the cornerstone of both WCW and TNA (now Impact Wrestling). However, that changed when he finally made his debut in 2014 during that year's Survivor Series. He began a feud with Triple H that culminated at Wrestlemania 31, with The Game picking up the win.

As Sting didn't have a full-time contract and was just working limited dates, predicting his return was a difficult task. The Icon however, didn't take too long before he could grace the WWE Universe with this presence.

When Seth Rollins' statue was about to be unveiled during the post-Summerslam Raw in 2015, Sting ended up taking its place. He then attacked Rollins with his trademark black baseball bat, and made it clear that he was the next in line to challenge for the WWE Title.
