Kaido’s whole reputation is that he is the absolute strongest in the verse. Land, Sea, or Air, always bet on Kaido. That’s just how it’s always been but if you take him out of the One Piece universe I dare say that Bass could teach him a thing or two. For starters, Bass is much faster than Kaido. He could run rings around the guy with ease and also has enough destructive power to put Kaido down. When you add all of that together, it means that Kaido doesn’t stand a chance here. He can’t dodge any attacks nor can he endure them. At the end of the day that means it is curtains for him. Bass wins.
