#1 John Cena - 16 Reigns

THE CHAMP IS HERE!!!!
John Cena has been a World Champion so many times in his career already that the quote above is now a catchphrase that he uses very often. John Cena is such a big name in professional wrestling industry right now that he can just show up any day after a lengthy hiatus and just wrestle a World Title match with the reigning World Champion later that night. This is how closely he is associated with World Title.
This trend first started at WrestleMania 21, where John defeated JBL in an underwhelming match to win his first WWE Title. This was followed by a lengthy period of 3 years in WWE Title scene where he held the title for two more lengthy reigns. Even though he is more associated with the WWE Title, Cena had two stupendous reigns with the World Heavyweight Title in late 2008-early 2009.
Before he won the World Heavyweight Title for the third and last time in October 2013, Cena added eight more WWE Title reigns to his name in just 4 years. He last won the title in an all-time classic with AJ Styles at Royal Rumble last year to tie Ric Flair's record of most World Title. With WWE adamant on breaking Flair's record, it won't be long before we see Cena hold a World Title above his head again.
