I think he’s dead. But the legend was the entire crew vs the world and then losing thru betrayal. The island God Valley prolly dissapeared bc he had the Yami Yami No Mi. And that’s why teach got it (inherited will + historical knowledge)
▪Well a lot of things happened and sanji never got up he only got up after some times while has his face fucked like ichiji against Kuri and far worse than when drake tailed him or his bleeding face after doffy's attack landed while he struggling to finish his speech and panting from that while also there is some struggle when he wanted to stand uo with that huff / puff if Big mom wasn't out and luffy tried to ascend to the roof he would have been choked this is casual King and made him like that without using his sword .
▪Base King stopped his sneak attack and overpowered him using his fighting style while sanji sweated .
▪King used his most useless form to make Sanji thinking he would die but Rs protected him while he was fucked in his face and panting and struggling to finish his words and he only appeared while trying to stand up after some time while King went to stop luffy after Meme got clowned Sanji has to thank Jinbei/franky for giving King a distraction or he would have been choked like ichiji against kuri who needed to use FS an OP ability while King didn't .
▪Hybrid swordman > Hybrid form > Swordman King in base > Zoan form > Base King
