That was all legitimate. The obeast was a professional strongman. Because of the it's personality and how it acted it literally almost caused riots because it pissed of so many at once. So there's a record of being an insufferable ass.  They set this up, and the waterbuffalo doesn't know what to do. So while Inoki is trying to entertain the crowd and do his job, this fatass just waddles around with his arms spread out and can only choke Inoki one handed occasionally. You can notice it tries to be entertaining at one point and attempts to run against the ropes and gives up. Then, with that shitty personality, it decides the best choice is to start full force chopping into the back of Inoki's head. Keeping in mind the obeast had strongman records.  Then Finally, Inoki has had enough, and just as soon as the fatass gets some in return it can't handle it. Inoki had been taking shit the entire time and the blob can't even handle anything in return, obviously it thought just being an asshole was what the crowd wanted to see and wasn't expecting to get anything in return. Obviously we're keeping in mind that this is pro wrestling, not a legitimate fight.  If I remember correctly the obeast was supposed to play the role of the heel and Inoki was supposed to be the one winning, but once it started the sack of fat decided that's not how it's going to go down, and Inoki being the professional tried his best to play along with it despite being obviously dumbfounded. Fat or not, I'm be happy to see that someone that acted like this fuckhead got what it deserved. It takes a lot of strength to stop those kicks. I'd have had to been pulled off..
