5. Man Mountain Mike 600+lbs
https://www.youtube.com/watch?v=L6W3YJn6MSc Time to roll back the clock a little now, as it was largely in the 1960s and 70s that we saw our heaviest wrestlers of all time; one of whom was Man Mountain Mike. Having spent much of his career wrestling in a number of territories, Mike eventually joined the WWE then known as the World Wide Wrestling Federation and wrestled there for six years between 1975 and 1981. During this time he was billed at over 600lbs. With the company, he formed a sizeable alliance with Crusher Blackwell, who at 474lbs just missed out on a spot on this list. The duo challenged for the tag team titles, but were ultimately unsuccessful in their quest. Hours of scouring the internet has yielded little to no evidence suggesting that Mike was not as heavy as the company claimed him to be, so on this one well have to take their word for it.
