These days wrestlers are all fit athletic types with the exception of a couple like the late big daddy V who missed his calling by a few years as well as a couple of others. Brodus Clay etc.
But back in the day, there were wrestlers whose whole gimmicks were that they were just big fat tubs of sh... Anyway, sadly this breed has all but died out, so let's cast our memories and votes back in time and pick which tub of it was your favorite.
i thought yokuzuna when i first saw the question but then i was torn between vader when i saw the options.
i'd lean towards vader because he was very agile and able to mix in the speed with strength. high flying acts with power moves... although compared to the other options he really wasn't as overweight. he was 6'5 375lb and primarily muscle. so basically he was like a really really fit offensive linemen (in fact he was an offensive lineman for the university of colorado)
so i voted yokuzuna since he was truly grossly overweight easily weighing 400-500lbs and i heard at times even weighing more than close to 800lbs
vader best big wrestler of the lot yokuzuna best grossly overweight wrestler
