From countless stories from other wrestlers, the consensus #1 badass of all time was Haku (Meng).
Word was the guy had stupid freakish strength, broke off handcuffs with his arms cuffed behind his back, would get pepper sprayed and it had almost no affect on him, and was a nice guy but if you got him mad he was terrifying, the only guy just about every other wrestler openly admits to being scared of.
There are stories of him biting off chunks of people in brawls, tossing big guys around like children and once putting two fingers inside a guy's mouth and breaking off some of his bottom teeth.
It's not surprising he comes from the Pacific islands and has that Mark Hunt retard strength and thick bones. Would have been interesting if he was in his prime now and he tried out the HW division.
A somewhat distant second place according to other wrestlers was the Barbarian, another Pacific Islander.
“There are 3 types of men: tough men, wrestler-tough men, and then there’s Meng.”-Arn Anderson
Very few men in the history of pro wrestling has garnered fear…legitimate fear for a single individual than Tonga Fifita. If the name doesn’t sound familiar, he was also known as Meng in WCW and Haku in the WWF. Regardless what you call him, make sure you do it with a smile and respect…because Tonga Fifita has one heck of a reputation.
The stories you hear or read are that of legend. Whether it’s gouging another wrestler’s eye out or breaking off someone’s bottom teeth in a brawl…Fifita has been called one…if not the toughest wrestlers in the business. A man who was truly feared and respected for his brute strength and unprecedented intensity. All it took was a certain look or glance from his eyes and you knew if you were going out of bounds.
Ric Flair
Ric Flair comparing MMA fighters to Haku: “Don’t ever think that anybody would mess with Haku. If he was a young guy and he got into MMA, my god — he’d have done everything! He was the toughest son of a bitch I’ve ever met in my whole life. No lie, take my word for it.”
Bobby Heenan
“The toughest man I’ve ever met in my life. “He took his two fingers on his right hand, his index finger and trigger finger, and he reached into a guy’s mouth and he broke off the guy’s bottom teeth.” Heenan added, ‘I wouldn’t have believed it, if I didn’t see it for myself.’ Bobby Heenan also claimed that Andre the Giant wasn’t afraid of anybody…except for Harley Race and Haku.
Jake Roberts
“If I had a gun and was sitting inside a tank with one shell left and Meng is 300 yards away, he’s mine, right? Well the first thing I’m going to do is jump out of the tank and shoot myself because I don’t want to wound that son of a bitch and have him pissed off at me.”
