[Discussion] Falling from 10k meters and surviving isn't an exceptional feat in OP terms.

[Rokudaime Hokage Naruto]

When you fall from that height you will reach a terminal velocity of little over 210 mph (if falling in the most aerodynamic posture). Assuming the crator Kaido created was about 5 meters deep, and also guesstimating his mass at 500kg, then Kaido hit the ground with a force of around 2 million newtons or around 200,000kg. Whilst this seems a lot, it isn't really much compared to Garp's punches which can crush mountains or the feats of other characters such as Jozu (with the huge piece of ice), Luffy's king kong gun destroying most of Dressrosa, Whitebeard stopping a moving ship with one arm without being pushed back etc.

But it is impressive that he wasn't even scratched, implying he could survive MUCH worse

...... Well those are the feats of the strongest characters your comparing a suicide too. Its still Badass and not many characters would doo hes interesting and cant wait for the next Chapters Oda better show him >.< I wont be surprised of he reveal all the Yonkous back too back. Too say at the last like everyone making there move after DD defeat

But Kaidou is strong but not the strongest its been stated he has been defeated 7 times it could be from the same or different people it seems he just cant die I believe the reason for him wanting an Army is too pull a WhiteBeard and attack the marines

He survived decapitation from the WG when he was captured many times

Kaidou > Roger in terms of Feats gg xD Roger got solo by hakiless Swords
