Sanji getting a raid suit really belittles everything the vinsmokes have done to him. He's going to wear the suit made by the man that killed his mother? The brothers that tortured him daily? It completely destroys his character and goes against the original message of Sanji not needing them.
People are saying he will have to use it when someones in danger, yet all that training he did for 12 years of his life, and instead has to resort to a suit from the family he hates as a reminder that he isn't strong enough without their help. Plus he loses his epithet that connects him to Zeff. Talk about destroying a character.
Maybe Akainu should send his uniform to Luffy and have Luffy wear that too. Or have Arlong send his Hawaiian shirt to Nami.
Sanji hasn't lost the "Black Leg" epithet. They don't put "Strawhat Luffy" on the wanted posters, they put "Monkey D. Luffy". Sanji has always just been listed as "Sanji" on his bounty poster, all that happened is that they tacked on the Vinsmoke name, which got the focus for plot reasons.
As to the raid suit itself, we don't know what's going to come of it yet, and Sanji's vehement distaste for his father's work seems pretty evident in the chapter itself. Until we're shown otherwise, I'm leaning toward Usopp and Franky dismantling the thing to harvest it for new tech.

Not knowing is fine, but to me it’s clear that he’ll enter the narrative again.
Hmm. I'm not seeing it yet, but to be fair, it's been a long time since I went over the Enel coverstory… Might just be missing some signs.
Regardless, I'd love for the guy to descend upon the New World thinking there's no one other than that bizarre Rubber-man who can stand up to him, only to get a haki-imbued fist to the face.
