On the different way s enemies were defeated, the parallels between Doffy and Croc are stronger.

Croc - Shichibukai, based on low-lying reptile, help a nation collapse (or at least begin to), fought Luffy underground, was punched up to the sky

Doffy - Shichubukai, based on a tall bird, believed he was above all else, saves a nation, fought Luffy in the air, was punched down to the ground

Credits to some guy Mangastream's comment section, just thought it was cool enough to share.
