Although I have seen I had already commented in this thread back in 2010 before someone brought it back from the dad, voting Sabu and Terry Funk, I am going to have to make another couple of suggestions.
After reading many wrestling autobiographies, it is clear to me that Meng/Haku is one of the toughest men ever to step into a wrestling ring. Everyone has stories about how terrifying and tough he was (I am not going to list them as most of them are already mentioned in this thread by others). But yeah....Meng was tough as nails.
Most wrestlers out there are tough as hell, simply to continue while living every day in pain with stiffness, soreness and contantly nursing injuries. To do what those guys do on a daily basis you have to be tough. know I couldn't do it, and 99% of people wouldn't either.
Yea I have about 20 Bio books on wrestlers and 14 of them have story bout haku just doing some crazy stuff or guys knowing not to fuck wit him.
in the POP shoot interview, barbarian said haku's name instantly as the toughest Guy in the business.
