No idea why people doubted him anyway. Stated to be relative to Roger. Put relative to WB in status. Oda chose to, with no prompt, mention "Shanks OR Rayleigh" when asked about what Shanks' CoC is capable of, etc...
Only one of them happens? Sure you can brush it off. But it's a consistent portrayal
This dude is probably ~ Shanks at least. Yonko+ level
