The legit toughest man I ever met (and ever likely will meet as this bloke was another level tough) wasn’t a trained fighter nor a weightlifter, he was just naturally big about 260lbs thick wrists had a gut as he loved a drink but was otherwise solid, I recall when everyone said a new top dog was on the scene and was making a name for himself as a bully they said he wouldn’t be beat as had extensive mma training well when they finally met the fight lasted long enough for a single punch to be landed leaving mma bloke unconscious with a broken jaw and was still in a slumber when the ambulance showed up, another one I witnessed was a lad fresh out the army trying to make a name for himself and was a bully and made the mistake of headbutting a female in my mates company, he very quickly hospitalised the lad and his father with zero effort, he hit like a bomb and was impervious to pain almost you literally had to kill him to stop him coming for you
Thing is I never once heard him mention who he was or how tough he was (were close for 10+ years during his prime years) never was a threat to anyone, could say anything offensive to him and he’d just laugh none of this I’m a tough guy respect me shit, only people he ever hurt unprovoked were bullies or cocky loudmouths, would do absolutely anything for you as well if he seen you outside fixing your car he would come out and help ect
