#7 Jon Moxley (fka Dean Ambrose)

Dean Ambrose, who is now known as Jon Moxley on AEW television, was a part of NXT, much like the other two members of The Shield - Roman Reigns and Seth Rollins. Ambrose joined WWE in 2011 and was a part of the now defunct Florida Championship Wrestling developmental territory.
Ambrose was involved in just a handful of matches on NXT, before he was called up to the main roster alongside Reigns and Rollins, and went on to make a major impact on WWE. Ambrose, though, never won a single title in NXT, unlike Seth Rollins, who was the inaugural NXT Champion.
But, Ambrose did win one world title on the main roster, winning the WWE Championship once when he cashed in his Money in the Bank contract at the PPV of the same name in 2016. He cashed it in on Rollins, who had defeated Roman Reigns just a few minutes earlier. That was the only world title Ambrose won before he left WWE for AEW in 2019.
