#7 John Cena - No
A surprise omission from the list of WWE Grandslam Champions is none other than the biggest star of the current decade, John Cena.
A winner of 25 titles in the WWE, Cena's main event status meant that 16 of them were either the WWE or the World Heavyweight Championships. Cena is also a five-time US Champion and a four-time tag team Champion besides being a two-time Royal Rumble winner and a three time Slammy award winner for Superstar of the year.
But one title conspicuous by its absence from Cena's trophy cabinet is the Intercontinental title. While Cena was an up and comer in the WWE, he was assigned to the Smackdown brand where as the IC title was on the RAW brand.
In fact, Cena came to RAW as the WWE Champion and never got a chance to compete for the title.
