#7 tied - Randy Orton (660 days)
Randal Keith Orton, also known as Randy, was bred for this business from the day he was born. The cocky youngster was shot straight to the top of the WWE, becoming the youngest World Heavyweight Champion in history within two years of his debut.
However, it wasn't just the WHC that brought him success, as the prestigious WWE Championship was placed around his waist on no less than eight different occasions.
Despite this, Orton actually has the worst average length for each of his reigns, with just 76 days separating his tenures with the belt. The Apex Predator certainly felt like an important Champion whenever he walked down to the ring with the strap, but it can be argued that none of his reigns really stood out from the other, apart from maybe his run heading into WrestleMania 30.
