Just wanna say I think it's worth noting that Momo & Oden are a pretty clear example of why Bloodline doesn't truly mean anything in One Piece. It doesn't make you strong.
You could be the son of a really powerful character but that alone doesn't automatically make you special. Characters aren't strong just because they had a strong parent.
The same would go for Zoro if he turns out to be the descendant of Ryuuma or something. Lineage doesn't matter. Only effort.
And Since the only thing that matters is hard work and your own effort, if Momo worked hard I'm certain he could surpass his father.
