#3 Matt Hardy
Matt Hardy is a renaissance man. So far, his time in AEW seems to be touching upon earlier iterations of himself, including his Attitude Era character, as one half of The Hardy Boyz. Matt Hardy got his start alongside Jeff Hardy in WWE and was thankful for his time there. But he was creatively unsatisfied.
In an interview with Chris Jericho, he stated why he left WWE and said:
"They tried very hard to sign me. They have offered very good money, but I know my role would have been minimized. For me, more important than money right now, I like to totally utilize my creativity. And these last 3, 4 years I have to do this, I want to enjoy it."
So far, that seems to be happening. His work in the Stadium Stampede match at AEW Double or Nothing 2020 was entertaining and showcased his creative flair. More importantly, he is now aligned with Private Party in a mentorship/manager role that is a callback to his roots as a tag team star.
Hardy has only been with AEW for a few months now, but he seems to be having the time of his life in the promotion.
