Ranking Every AEW Surprise Debut From Worst To Best
1. Jon Moxley
It takes something truly special to edge out Sting's appearance at Winter is Coming, and that something special here is the AEW arrival of Jon Moxley.
Having given his WWE notice the day after the 2019 Royal Rumble, the former Dean Ambrose's time with Vince McMahon's sports entertainment juggernaut was to come to a close once WrestleMania 35 was in the rear-view mirror - and less than two months after that edition of the Showcase of the Immortals, Mox made his shocking AEW bow.
Of course, that first AEW appearance came in the aftermath of the inaugural Double or Nothing's main event. With a victorious Chris Jericho taunting the crowd after toppling Kenny Omega to retain the AEW World Championship, the Death Rider made his way through the crowd to drop Le Champion where he stood.
Debuting babyface laying out the cocksure heel champ? That's pretty standard. What took Moxley's arrival to an entirely different level is in how he and Omega bounced off each other.
Ever the opportunist, Mox looked to hit his Paradigm Shift on the Best Bout Machine - only for Kenny to counter this move, leading to both men brawling throughout the arena, before Moxley memorably nailed the Paradigm Shift on the giant chips set, then threw Omega to his doom.
