By the end of this arc,
The last Calamity will be Standing is Jack who was being shitted on by fans
The last Tobbi Roppo will be standing is Pageone who was being shitted on by Fans
If that happens, I would laugh SO HARD from Oda's choices!
Pageone truly deserves respect... a true tank!
By the way, for anyone who doubts him, last chapter it was PROVEN he has Haki (observation at least)
Reason is BOTH him and Ulti sensed Luffy's haki from the dust.... he was the one to even tell Ulti he's still standing and she said yes I know I know... the dude is a confirmed observation haki user (and Stealth Black) STilllllll was able to sneak on him many times.... Invisibility is STRONK
Im pretty sure BM didnt train much if at all to get to yonko status, thats what i mean by raw talent/potential. Im sure kata has it, but since he was already strong enough, he just stagnated. I think his fight with luffy reignited his fighting spirit and drive.
Jack is 28, falling within these guys' generation, so the mans got plenty of room for growth as the years go down. That very well maybe what decides to do. He looks like Kaido's protege if anything, so wouldn't be surprised if he's the Calamity that survives Wano and goes on to do his own thing.
He can still become stronger. Aka was 55 and is likely stronger now compared to MF because of the Ao fight. Also if Kata becomes the leader of the BMP and can fly with his own wings maybe this will free himself more and his will can be greater
