Not even trolling, I would say he stops around number 8 or 9. I don’t think people grasp how fast platinum sperm is, outside of momentary bursts of speed, Kaido (and really all OP characters but Kizaru) absolutely are not keeping up with PS.
If Kaido somehow beats Platinum Sperm then he certainly loses to Orochi. Orochi’s maximum firepower is some low planetary level shit, just him charging up his Gaia cannon was shaking the earth.
