#2 Dean Ambrose

Dean Ambrose shocked the WWE Universe with by returning on the road to SummerSlam last year. Even though Ambrose did not compete in a match at SummerSlam last year, he was present ringside as Seth Rollins' partner.
Ambrose helped Rollins to avoid the distraction caused by Drew McIntyre, who was there as Dolph Ziggler's bodyguard. Ambrose was a big factor in Rollins' second Intercontinental Championship win.
The Unstable One had a great run in WWE last year, which was also his final run. We got to see some magnificent matches when The Shield reunited last year. Later that year, Ambrose turned heel and won the Intercontinental Championship from Seth Rollins.
No one thought that Ambrose wouldn't be a part of WWE this year. Now known as Jon Moxley, working in AEW, no one even remembers that Ambrose worked SummerSlam last year. Although Ambrose had a small part at SummerSlam in 2018, he will definitely be missed this year.
