Robin was the Oden parallel on the crew.
They joined pretty similar, both crews were opposed and they both can read and write the ancient language...
You know what, im not a fan of this parallel thingy, luffys crew doesnt have to be paralleled to rogers crew
In this fandom, I think they being so much into these parallels that at some point they're losing it essence,
It's easy to say that certain character is parallel another one because youre nitpicking what's similar in them. But that disregarding the fact that there are tons of characteristics that make them entirely different, but this fandom would take it as if its parallel just because there are certain similiarities as they try to make things fit on what they believe in.
I can directly say robin is paralleled to oden based on what you said, but I can also say otherwise since they're still different.
Robin didnt want to go to adventure because she wants to. SHE HAD TO, since shes being hunted by WG. Oden is not like that
Oden was a heir of a certain kindom oppressed by a pirate crew, Robin was not.
Robin joined Crocs crew for protection and hide against WG, the same when she first joined SH prior to events in Enies Lobby. Oden was carefree and just wanted adventure.
See. You can be subjective on who is parallel and who is not, and fit it conveniently to your beliefs.
The only parallelism I believe Oda is making an effort to do was Roger and Luffy, and it was depicted in panels. I remember this scene during the meeting of roger, wb and oden, the reaction of oden and wb to what roger said was exactly the same with sabo and ace reaction to what Luffy said when they re still kids. You also have to note that even the bandages of oden and wb was similar to sabo and ace. That's an undeniably parallelism.
But the others, just like what you mentioned, you only nitpicked similarities
