As of 2015, some of the most popular WWE wrestlers seen on the company's weekly "Smackdown" broadcast include John Cena, Brock Lesnar, Seth Rollins, Kevin Owens and Roman Reigns. The company no longer has its roster split between the "Raw" and "Smackdown" broadcasts as it once did.
John Cena won the U.S. Championship from Rusev at Wrestlemania 31. He has also held the World Heavyweight Championship belt 15 times, one short of the all-time record held by Ric Flair. He gained some exposure outside of wrestling circles with a guest appearance in the film "Trainwreck" in 2015 and is a very active participant in the Make-A-Wish charity program.
Brock Lesnar began his career in WWE before moving on to a long and successful career in mixed martial arts. Lesnar signed a three-year contract with the WWE in 2015 and indicated in an interview the same year that he may be entirely done with MMA.
Seth Rollins won the World Heavyweight Championship belt at Wrestlemania 31. Kevin Owens won his debut match on the main roster over John Cena at the Elimination Chamber pay-per-view in 2015, quickly becoming one of the company's top characters. Roman Reigns participated in the World Heavyweight Championship match at Wrestlemania 31.
