4. Yokozuna
Yokozuna, a Samoan being portrayed as a Japanese sumo wrestler, was physically one of the most intimidating superstars in WWE history. In his prime he was unbelievably agile and flexible to go along with his immense build, and almost single-handedly redefined what a big man could do in a wrestling ring. Yokozuna is a two-time WWF Champion, defeating Bret Hart and Hulk Hogan to do so. Whilst we should dismiss his first reign as it was over in a matter of seconds, his second reign as the top guy lasted 280 days, a period as intimidating as his size was. Beginning this reign by proclaiming that he had ended Hulkamania, Yokozuna was able to effectively draw heat due to this and simply from the fact that he was foreign. Throughout his reign he would compete against Lex Luger, making obvious use of the patriotism struggle, and the Undertaker. Defeating these two imposing specimens would certainly result in an instant boost for whoever could stop this behemoth. In the end, Yokozuna would drop the championship to Bret Hart at Wrestlemania X, but will forever go down in history as not just the heaviest, but one of the greatest heel champions in WWE history.
