But PK is a title too, Oda don’t want to have cluttered intro boxed perhaps?
He became PK a year before dying...
You still didn't answer why he wasn't WSS despite being Great Pirate for years.
Mihawk , Katakuri, Oden, Rayleigh and Shiryu
Are dudes who are legendary among the mightiest but not equal to Great Pirates
Mihawk is below Shanks. Might even be below Benn too
Oden below WB
Katakuri below Linlin
Shiryu below Teach
Rayleigh below Roger.
His WSS means nothing since he is barely put above YCs and couldn't beat Young Shanks.
