Sanji and Zoro have always had two distinct, although complementary, roles in the crew and I was perfectly fine with that. Sanji has never been just a fighter and I don't want him to be one. I'm ok with Zoro getting the spotlight when fighting is needed. Sanji usually had his own stealthy thing to do and a smaller fighting role was totally acceptable. Both were useful.
I'm not ok with what CL⁶oda has been doing since Sabaody. Sanji has slowly been turned into a gag character that sometimes tries to be stealthy, fight or do anything remotely useful and ends up failing most of the times. And the rare times he doesn't (the cake diverting BM attention, Queen), whatever is happening around him dwarfes his achievements. And the worst part is that CL⁶oda is clearly aware of what he is doing, the wing thing the most obvious hint of this. I can't accept this does not have a greater purpose. Vegapunk didn't even mention Judge once.
Sanji getting CoC is the first step of a long, necessary coming back. The sign he is still relevant. His character has been butchered, he has never been just one of the strawhats. He should devise the escape plan from Egghead, he should clash with Kizaru, his exoskeleton should catch Vegapunk attention. You know, do useful thing a character usually does. Every once in a while. Saving Bonney from a fodder just so she could be captured by Saturn doesn't count.
Discussing Sanji vs Zoro is useless at the moment
Oda has had Sanji as the Antitype. It didn't really hit me until this flashback with Kuma, that that is what exactly our boy is.
In the bible, you have what's called a type and an antitype. A type being a thing or person that foreshadows a later fulfillment, or what this forum likes to label parallels. Example, Adam, Jesus, John, Jesus etc.
Sanji is Oda's Antitype, in several ways more than one:
"Betrayal/Leaving the Crew"
Types:
-Pushed others away for their own good, trying to handle everything on their own and running away - NAMI
-Pushing others away and giving themselves up, while making a bargain or their lives, haunted childhood - ROBIN
-Fighting Luffy, but also having secret feelings of inadequacy, and low self worth - USOPP
"Brother to Luffy"
Types:
-Son of someone infamous who hates his father and tries to distance himself while looking up to someone else as his father, world forcing his bio father on his identity, sacrifice by mother to save him, prefers mother over father. Hot tempered on the outside, caring on the inside. - ACE
-Blonde royal/noble runaway with family issues who disowned their family, uses fire, color of blue, intelligence, tactician, voice of reason, wits. - SABO
"Other"
-Kind-hearted empathic human forced (or at risk) to become an emotionless cyborg for those they love. Lose free will, memories, who they are by technology. - KUMA
-Venus references (see my other thread too many to list), Saturn references (5th Gorosei, Black Sun, Devil, Goat, Science), Ju Peter (Blonde, 5ht Planet, Agriculture(food), Sky Father/Sora means Sky, possibly lightning), Mars (Bird Gorosei, God of War/Warmongers, Mercury (unsure but probably something) - GOROSEI
-Sun References and Nika, SAN JI 3 2 SAN NI SUNNY, Nika parallel images, Leading Luffy in the Skypiea dance, sharing this weird sun connection. - NIKA
-66s EVERYWHERE IN THE STORY - GERMA66
-Something as small as M66 being a SPIRAL galaxy in the constellation LEO a lion. Like Sanji a spiral is in Sunny a lion.
-Odds and ends that tie Germa or Sanji everywhere.
All of this and more, has one thing in common. Sanji. All of it can be found in him, his symbolism, his backstory. Elements of so many people, and their own backstories.
Sanji reflecting and changing, and being put into every situation Oda can is him being this antitype that Oda isn't ready to complete yet, and so he's stalled. But if you just look at the story like a puzzle, it's all there.
