Seth Rollins
Seth Rollins was a heel in July 2016 and was still Stephanie McMahon and Triple H's puppet. Being the Authority's guy, Rollins was directly inserted into the Universal Championship match scheduled to take place at SummerSlam that year.
The Architect has now turned into the Kingslayer as Rollins has transformed himself from the top heel to the top babyface of the WWE entering 2019.
Finn Balor
The New Era of RAW kicked off with a fatal 4 way match between Finn Balor, Rusev, Cesaro and Kevin Owens, with the winner advancing to the night's main event. Finn Balor made his in-ring debut on RAW and even emerged victorious from the match.
Balor went to win the become the first Universal Champion as well but had to relinquish the title due to an unfortunate injury. Currently, Finn Balor is still performing on Monday Night RAW but the leader of Balor Club is no longer the dangerous superstar that he seemed on his first night on RAW.
