I think everyone knows Shanks because he has one arm.

It was eaten mainly by people living in nearby waters.

But at this time, Shanks’ bounty is already 1.04 billion.
Even at that time, he was quite strong, but could his arms be eaten by the sea kings that appeared early on?
In episode 1, Luffy defeats him in one blow.

In fact, didn’t Luffy’s inner Nika awaken and his counterattack to protect himself hit Shanks and ate his arm?
