Underworld and Bounty
We know that Jack of Kaido got horn and looks like got a jaw/chin like morgan axe-hand. And I found other, maybe this horn guy is jack, and he’s bald!
Luffy’s bounty. Bounty’s pic look being taken at departure from Fishman Island. Impact of against Yonkou
Zoro. From Fishman Island battle.
Robin. From her Giganto Manos battle.
Franky. At Fishman Island battle.
Usopp. At Dressrosa after against Sugar.
Sanji. Right after seeing mermaid at Fishman Island. Impact of hidden birth sign?
Nami. Unknown. Maybe at Wano territory
Chopper. At feast of Fishman Island.
Brook. Right after Sabaody appearance.
And more interesting is I highly assume that next arc will be about Big Mam vs Kaido. Sanji in the Kaido territory, japan theme, Wano.
Luffy will be in Big Mam territory, china theme, Zou.
Why? Remember fishman island, Big Mam, China theme
Punk Hazard, Kaido/Joker, Japan theme
Dressrosa, Kaido, Japan theme.
Big Mam Pirates, china theme.
Alright, Let’s Oda draw the detail
Note: this is just assumption
