#1 Finn Balor
Definitely the most surprising name on this list, Finn Balor, defeated Roman Reigns on his very first night in WWE. Balor, in his second match on the main roster, defeated Reigns clean to qualify for the Universal Championship match-up against Seth Rollins at SummerSlam 2016.
Balor was presented as a major superstar on his very first night, and seemed destined for great things in WWE. He won the Universal Championship, defeating Seth Rollins, but had to relinquish the championship the very next day.
Balor never reached the heights of his pre injury run, and has struggled to find a proper spot for himself on the main roster. Just like Strowman, Balor is yet to win a single championship ever since he vacated the Universal Championship.
Finn Balor arguably became the top babyface on RAW after Reigns' departure, and WWE should make sure they make him the star he deserves to be!
