#4. Big E

Of all the superstars on this list, few have undergone the kind of transformation that Big E has since he made his main roster debut in 2012.
Initially appearing as Dolph Ziggler's bodyguard, Big E spent his first 18 months on the main roster working as a mid-card talent, even picking himself up an Intercontinental Championship victory at one point.

Things would change for Big E when he joined Kofi Kingston and Xavier Woods to form The New Day in 2014.
The group, who were originally rejected by the WWE Universe, has gone on to become one of the most influential tag-teams in modern wrestling, capturing numerous tag-team titles and making major draws of all three superstars along the way.
