Oda used the word 'Saikyō Seibutsu (最強 生物): which translated as The Strongest Biological Being / The Strongest Creature Among All Beings. Seibutsu includes all living things in the world, including humans. The reason why free manga sites misspell Kaido's title is because the English word "Creature" has plural meanings, but in the original scan there is no ambiguity because the word 'Seibutsu' is the one being used.
You can do a quick research on what Seibutsu mean:

Any living being on planet earth is weaker than KAIDO by definition.
Besides that I also saw the news that only Kaido and King faced the red haired pirates, that's good...
SHANKS probably didn't want a man-versus-man fight...
But the point is: Kaido recently said it wasn't easy to get YAMATO's DF...
Did KAIDO initially start fighting all the HRP and then SHANKS negotiated the DF or Kaido himself took him.
Shanks and his entire team, against KAIDO and KING, negotiating?
Is it fear or respect?
And with Kaido saying that ODEN was the only one to thrill KAIDO in 2 decades that means KAIDO was just playing with BM for 3 days...
And apparently SHANKS is weaker than ODEN.
1st - Enma was the only sword to pierce kaido deeply.
2nd - No one after 20 years has excited kaido as much as ODEN, and his luck hit in the weaker form of KAIDO,this means that kaido was playing with BM.
To tell the truth it's not that Kaido was kidding, he just wasn't giving it his all, just like BIG MOM wasn't either since he was without his homies, we talked for years in this forum that it was just KANABO versus NAPOLEON and a fight of physical strength,that obvious would end with the victory of the strongest living creature on planet earth.
But I won't deduce things 100% from that perspective, honestly all current emperors in my opinion are > ODEN > Akainu.
it was also mentioned on SBS that Kaido's club isn't special, but any weapon just because it's being wielded by Kaido can become a LEGEND! According to SBS.
Even though it doesn't have a rank, but if it stays in the hands of Kaido one day it shall also become a legend.
