#2 AEW's PAC
Oh yeah, AEW's Death Triangle is gonna be a major part of this list. PAC and Andrade just barely missed each other while in WWE. PAC was responsible for the initial explosion of popularity of NXT, carrying the gold and dishing out a series of match of the year contenders. As he moved onto the main roster, Andrade showed up and took over the Black and Gold Brand.
Before we could get these two in the same ring in WWE, PAC was already gone from the company, and since leaving he's only gotten more aggressive.
The man formerly known as Neville just came off of an AEW Championship three-way match at Double or Nothing, which is considered by many fans as one of the best three-way dances in pro wrestling history.
What sets Pac apart from the rest of the herd is his intensity and that pure hatred that you feel from his eyes anytime he steps out on Dynamite. The man has a nasty mean streak, something that he shares with Andrade. We saw that characteristic emerge from him once Zelina Vega began managing him in NXT.
Thinking back to his time against Johnny Gargano during their spectacular feud for the NXT Championship, I can still picture Andrade driving his knees into the skull of Gargano while his head was resting against the steel ring post.
Both of PAC and Andrade are vicious, and it would lead to a pretty intense feud heading into what would be a spectacular match for AEW.
