Evil brother with superiority complex, noble but raised by pirates, really kind both of them and etc etc.
Red hair shanks and red leg zeff
Never bought the Shanks-Sanji parallels but lately the similarities are too much
I didn't even make the Red Leg Zeff connection. Don't think I've seen that one before.
After Luffy, Sanji is the most plot relevant Strawhat. From the beginning, he was the only East Blue recruit not from there. We learned he was from the North Blue almost 200 chapters after his introduction. Sanji's was the only initial flashback that didn't address where he came from. We just found that mfer on a boat and very few stopped to consider how odd it was (though the Mr Prince thing did spin a few theories).
The parallels with Shanks are absolutely there and absolutely intentional. Oda made him an actual fucking secret prince of a powerful nation relevant to their interest in the New World. We even had Sanji put on a performance around his blood relatives, much like Shanks did in the Holyland. The Germa cloning science and Kuma/PX Clones, and the links between Judge and Vegapunk - I mean, c'mon.
They're both secret nobles with secret origins stories considered black sheep among their blood relatives, possesses peculiar eye features and live lives heavily shaped by the love for their found families and chosen parental figures in particular.
Do you know who else that sounds like? Someone also very relevant to Shanks. Who also targeted for knighthood and eventual possession.
I've little doubt Shanks saving Luffy was a genuine act of love that inadvertently liberated him from Imu's clutches.
Given Thriller Bark's relevance to this current arc, I find it highly interesting to look back on Sanji's shadow rebelling in the name of love also.
