How was he KO'ed if minutes later he sprang out from underground in front of Luffy? Yes you are fucking bizzarre with your nonsense, Akainu took a punch and WB had half his brain and chest removed.

You need help buddy.
Akainu isn't ko'ed now.
Whitebeard was old , Out of prime stamina , Constant heart attacks , already stabbed once. And was fighting An admiral and still managed to KO him after half head and hole in chest.
Don't quote me again.
