Yokozuna (April 4, 1993 - April 4, 1993)

Yokozuna's first reign as WWE Champion was as brief as one could be.
The purportedly Japanese sumo wrestler (he was actually Samoan) was undefeated since his debut on WWE television six months earlier and had squashed every superstar he had come into contact with, most notably Macho Man Randy Savage in early 1993.
However, despite the win streak, most onlookers expected WWE Champion, Bret "Hitman" Hart to turn back the challenge of the foreign menace.
'Zuna, who rarely spoke and had the long past his prime, Mr Fuji as manager did not appear to be WWE Championship material.
Therefore, many fans were shocked when 'Zuna pinned Hart to win the title after salt had been thrown into Hart's eyes, subduing him for 'Zuna's big legdrop.
Perhaps overconfident from his upset win, Yocozuna immediately challenged Hulk Hogan post-match. That decision would come to haunt him just a few minutes later.
