#3 Sting's highly awaited WWE debut - WrestleMania 31
Much to the entire Pro Wrestling World's shock, Sting made his WWE debut in 2014 when he crashed The Authority's party at Survivor Series, helping Team Cena pick up a win over Triple H and co.
Sting's debut was surely considered as one of the greatest WWE debut's of all time, given that he was the very last WCW Original who was yet to jump ship to the WWE, however, after all these years, 'The Icon' had finally made up his mind and made a huge impact on his very first appearance in the WWE.
Not only did Sting helped Team Cena win but his interference also led to the disempowerment of Triple H and Stephanie McMahon. Within the next few months though, things took a turn and on January 19, 2015, the WWE careers of Dolph Ziggler, Eric Rowan, and Ryback were on the line. However, thanks to yet another outside interference from Sting, all three men were once again rehired by WWE, as Sting and Triple H had a face-to-face confrontation with each other.
In the build-up to 'Mania 31, Sting met Triple H in the ring in yet another heated confrontation and challenged 'The Game' to a dream match come true at WrestleMania 31. Despite Triple H winning the bout and the outside interferences from both nWo and DX, Sting's first-ever Road To WrestleMania remains a very memorable journey.
