Is Teach going to choose one of the targets and focus on one of them, or go with 2 different teams after 2 ancient weapons?
For now, we see that BB Pirates can go into;
Solo missions:
- Burgess goes to Dressrosa to steal Flame Logia.
- Lafitte goes to Marijoa and later Umit Shipping to gather information and make deal.
Duo missions:
- Shiryu and Lafitte goes to Dressrosa to pick up Burgess.
- Aokiji and Augur goes to Whole Cake Island to kidnap Pudding.
- Devon and Augur goes to Egghead to steal Saturn's appearance.
Trio mission:
- Blackbeard, Devon and Vasco goes to Amazon Lily to steal Hancock's DF, ends up kidnapping Koby.
Quadruple mission:
- Blackbeard, Doc Q, Augur, Burgess waits one of the 3 billion captains to show up on the road from Wano.
So they don't need to move with all of the crew.
How are they going to move and steal 2 Ancient Weapons from Fishman Island and Wano? Plus they need to guard Garp and Pudding unless they carry them when they go which I doubt.
Perhaps Oda will send Aokiji, and some other fodders like Caribou, Don Krieg, Gin to help him, and some other unknown members of BB Pirates (not titanic captains) to Fishman Island to kidnap Ancient Weapon Shirahoshi, because Aokiji's freezing ability is perfect to the underwater drowning threat while fighting on Fishman Island, and Luffy will try to stop Aokiji there, potentially beat him and end Aokiji's ties with BB Pirates.
Remember, Fishman Island is the place where Luffy learned about Aokiji's loss vs Akainu for the first time, that would be interesting for them to face each other again in that place and as an Emperor, Luffy will protect his territory.
Or Shanks might involve in this as he follows Teach's movements.
But Oda would perhaps compensate for that failure by giving the Pluton Ancient Weapon from Wano to BB Pirates, so they can conquer World Government or be equal partners with them. Or Caribou when no one notices steal Shirahoshi like he did before, and even if Aokiji or someone else fails, perhaps he can manage to escape with Shirahoshi. There are many possible scenarios how Oda will go from here.
I believe Shiryu should go to Wano due to Wano connections, but there is someone needed to guard the prisoners so not sure about that.
