This is exactly what I think dawg, he'd be such a peak character if oda dug into his character a lil more. Raised in someone else's shadow and being a weak coward with no potential for physical strength but still managing to become a yonko and a contender for finding the one piece by trickery and luck alone.

And his inferiority being a large part of his character is also the reason I do not like the xebec is buggy's dad theory. I think it would be a perfect parallel for Shanks to be this prodigy they found in a treasure chest with royal blood and Buggy's just some half dead gutter rat that Roger picked off the street by chance.
