I think they clashed/briefly fought in Stampede too?
Sanji vs Croc would be so good. Would be funny if his heat turns Crocs sand into glass lmao. Maybe Sanjis exoskeleton can protect him from the glass shards then? Or Crocs cutting powers in general?
What if he tries to drain Sanji though?
Croc actually instantly bisected Akainu at Marineford too!
I was wondering about the sand/glass thing, too. Really cool if Oda goes that route:
Luffy beat Croc by using water to stop his sand.
Sanji beats Croc by using fire to stop his sand.
(Sanji is walking outside of Mary Geoise, and blinks, leaping out of the way just as a geyser of sand appears beneath him)
Crocodile: "Nice CoO. You were a smart one, even back at Alabasta. If it wasn't for you, who knows where I'd be, honestly? You saving your captain at Rain Base change everything. I was just chasing the ghost of Pluton... but Mugiwara destroyed that dream completely."
Sanji: "I'm glad he ruined it, you crappy Croc. I'll never forgive you... for how you made Vivi cry."
Crocodile: "Can't blame you for that, but it was just business. If it means anything, I was happy to see her survive that assassination attempt. I actually laughed when I saw the papers about you, though, you know, you cunning cook? "Mr. Prince" was actually royalty, the whole time. In Alabasta, I didn't even know you were part of the Straw Hats, let alone that you were Germa scum... This time..."
(Crocodile chomps his cigar and spits it into the sand growing beneath him)
"You have my full attention, Mr. Prince. I'll suck every last drop of water out of you, you curly-eyebrow-bastard, until even your bones are dust."
Fuck I love Crocodile
