#1 Seth Rollins

After Roman Reigns' departure from the company, Rollins is now the MVP of Monday Night Raw. He had one of the best runs in the WWE as a heel and is currently running things on the brand as a face.
He turned heel in 2014 by breaking The Shield. This was one of the most shocking heel turns in the WWE which helped him grow in the company.
He later aligned himself with The Authority and was all set to win the Universal Championship against Kevin Owens, but Triple H betrayed him.
Later, Rollins feuded with Triple H, and eventually, Rollins managed to become one of the most over babyfaces in the PG Era. So far, 2018 has been the year of Monday Night Rollins, and it would be interesting to see how he would be booked now as he is feuding with Dean Ambrose.
