#4 Antonio Inoki - 6 days
Antonio Inoki is a man who many know the name of, but not as many believe was ever WWE Champion. Alas that was the case back in the late 70s, after the Japanese Superstar pinned Bob Backlund before immediately vacating the belt in a rematch six days later.
Despite this series of events, WWE don't officially recognise Inoki as being a former champion. The reason for this, we assume, is that they wanted to extend the reign of Backlund and make it seem like he never lost it.

Unfortunately for the company, we actually have access to the internet and are able to find out the truth ourselves.
Inoki was a one of a kind legendary performer, and he deserves a bit more notice than he gets in the grand scheme of professional wrestling. The icon will always be a part of the WWE family one way or another, but perhaps not in the way that a lot of fans desire.
From six days down to one as we look into one of the most underrated superstars in WWE history.
