On April 25, 1963 the original Nature Boy Buddy Rogers defeated Antonino Rocca in Rio de Janeiro, Brazil to become the first ever WWE World Heavyweight Champion. Since then the title has (officially) changed hands on 119 different occasions, with the current champion Seth Rollins being the 45th WWE Superstar to hold the belt. Among these 45 champions there have been some of the biggest giants to ever enter the ring such as 'The Big Red Machine' Kane (7ft 0in), 'The Worlds Largest Athlete' Big Show (7ft 0in) and the tallest champion of all-time, WWE Hall of Famer Andre the Giant (7ft 4in). But who cares about the big guys?! If theres one thing that the WrestleMania XXX main event proved its that wrestling fans love cheering on the smaller underdog wrestlers. This article lists the 10 smallest of these wrestlers to have defied the odds and won the biggest prize in sports entertainment, The WWE World Heavyweight Championship. Honourable Mentions Dolph Ziggler (6ft 0in) and Chris Benoit (5ft 11in) were both winners of the now retired version of the World Heavyweight Championship which existed during the brand extension (when the current version of the belt was known simply as the WWE Championship).
