Stop overrating Loger and Lewgate. One was scared of BM and the other was scared of Kaido.
Yes and then we also found out Kaido is the strongest creature in history, so the current strongest (Kaido) is stronger than any in the previous generation.
Yes, Roger and Wb PRIME, were put by kaidou as well as Shanks as only being able to fight him, and not being superior people to him, kaido sees it that way, that WB and Roger are only people capable of fighting him, and not superior to him, Shanks is included in the statement and has the same treatment as Roger and Wb Prime, meaning that Shanks is at least on par with Roger and Wb Prime.
The strongest of this era > strongest of the past era.
KAIDO > ROGER.
With this, the level of the other characters from the Kaidou era will also rise above the previous era.
