Queen is still far from being defeated and it's still rather uncertain whether or not Sanji will solo him. Meanwhile WsW might already be out so eventually Jinbe on Land himself could possibly stand on YC2.
Jinbe looking like the badass that he always has been. So glad he's in the crew.
But I'd be pretty disappointed if that's it for Who's Who. Ulti took a Thunder Bagua from Yamato and a life threatening attack from Big Mom plus a few minor attacks and was still walking. Although after Ulti recovered from Yamato's attack, it was mentioned how tough those dinosaur powers are, so who knows.
Nika is just a way Fisher Tiger was known as during his Marie Joys times. Jimbe knows it and earing WW talking about him after declaring how he wants Luffy to die bad made him snap.
It's not Luffy like most of y'all seem to believe.
