#2 Viscera
Possibly one of the most intimidating looking men to ever enter a WWE ring, Viscera, or Big Daddy V was one of the largest men as well. He main-evented Summerslam in 1995, after having won the King of the Ring pay-per-view that year. Viscera was best known for his work in WWE and his run as one of the minions of the Undertaker, though he would later go on to feud with the Dead Man later.
He was immensely overweight with a height of 6 foot 9 inches. While ultimately never really successful as a wrestler, it was the look that he brought into wrestling with his massive bulk that was his claim to fame. Not fast in the ring, and not really capable of doing too many moves, he was overexposed and the fans got tired of him fast.
Unfortunately for him, it was his weight that claimed his life after he died in the shower of a heart attack at 43 years of age. He died too soon and never lived up to the obvious potential that he had.
