#3 Luchasaurus
While AEW has been criticised for lacking characters, that's far from the truth, as Luchasaurus (the former Judas Devlin in NXT) is one of the most interesting in the world. While you may not expect it when you see him, Luchasaurus is a very deep person, with a Masters Degree, and his partnership with Jungle Boy is perfect for today's wrestling.
We've seen him on both AEW shows so far, but similar to Private Party and Darby Allin from Fyter Fest, we want to see the company delve deeper into the man known as Luchasaurus. While it doesn't have to be a singles bout, just a video about his background and time in the ring will allow new AEW fans to become familiar with him.
It's clear to the fans that his partnership with Jungle Boy is likely what's going to get over the most for Luchasaurus in AEW, but he's a great performer, and he needs to be given a bit of time to show just how good he is.
