WWE's poster boy has been on Raw since 2005. There's been a few brief injuries, but he's noted for having almost miraculous recovery times, meaning that he's managed to be active on Raw for almost a solid decade. Out of his 416 matches, there's been numerous match of the year contenders. His Raw match with Shawn Michaels in 2007, or his Raw match with CM Punk in 2013 are the stand out candidates. But there's also been plenty of atrocious matches, which has resulted in Cena becoming the most polarising WWE superstar in history. Ironically, that's helped to make even his bad matches watchable, as the duelling crowd chants make for an irresistibly electric atmosphere. Given how he whips the crowd up, WWE are always keen to book him in Raw main events. At this point, he's headlined the show for over double the time that The Rock or Stone Cold Steve Austin managed. Love him or hate him, he's a Raw institution.
