#4 Hollywood Mania
John Cena was already a household name during his full-time WWE career, with his "You Can't See Me" gimmick gaining significant mainstream attention. However, in the past year, Cena has gone complete Hollywood.
Cena has starred alongside the likes of Jackie Chan, Hailee Steinfeld, etc, major personalities in the Hollywood film industry. Cena's popularity has increased due to his appearances on prime time talk shows like Ellen and Jimmy Fallon, which bodes well for WWE.

WWE could use the newly gained popularity of Cena to sell out shows and make WrestleMania a bigger deal for the casual audiences.
Casual audiences are not overly aware of superstars like Seth Rollins and AJ Styles. Mainstream superstars like Randy Orton, Brock Lesnar, and John Cena are the only way to sell shows for WWE at the moment.
