Francis Ngannou apparently has the punch record at 129,000 units (whatever that means). They say his punch is like getting hit by a sledgehammer or a car. I tried to look up the hardest puncher before him but can't seem to find anything definitive. I see some mentions of Mike Tyson, Joe Louis, and the like. Was this just something folks weren't keeping record of or was there some record holder that Francis Ngannou displaced?
