The Wano war is all but set to be the biggest known war in the world of One Piece to date, possibly surpassing even the likes of Marineford. The war sees the Samurai of Wano team up with the Straw Hat Pirates and some other allies to take down Kaido's Beasts Pirates who rule over Wano, along with Big Mom.
With the Dawn of Wano being on the horizon, the war is likely going to result in victory for Luffy and his people. As with every arc, new bounty increases will likely be issued to several pirates once everything is over.
10 Roronoa Zoro
Zoro is the Combatant of the Straw Hat Pirates and one of the strongest swordsmen in the story. He aims to defeat Mihawk and become the strongest swordsman in the world.
Being Luffy's strongest subordinate, Zoro is bound for greatness in the Wano Country arc. If he goes on to fight the likes of King, Zoro will likely get a bounty of over 1 billion berries, and something around 1.4 billion berries.
9 Edward Weevil
Weevil is the self-proclaimed son of Edward Newgate and a former Shichibukai. He's said to be one of the most powerful characters in the One Piece world, with Kizaru comparing his power to the likes of Whitebeard in his younger days.
Now that he's no longer a Shichibukai, Weevil will definitely get a big bounty. Keeping his reputation and danger in mind, something around the 1.6 billion berries mark would be ideal for him.
8 Eustass Kid
The captain of the Kid Pirates, Eustass Kid is an incredibly strong character who is playing a big role in the Wano Country arc, just like Luffy and Law. His current bounty is about 470 million berries, however, after taking on Kaido in a fight, it'll likely become much bigger.
Kid, being one of the main players, will likely get major credit after the war of Wano wraps up. A bounty of 2 billion berries seems adequate for Eustass Kid once everything is dealt with.
7 Trafalgar Law
The leader of the Heart Pirates, Law hails from North Blue and is one of the most important characters in the story right now. Like Kid, Law is one of the Worst Generation members and he currently has a bounty of 500 million berries. Law is the catalyst for the War of Wano and the person who 'broke the gears.'
He's also going to play a big role in the fight against Kaido and gain a huge bounty increase after everything is done. Law's bounty is predicted to be around 2.2 billion berries.
6 Boa Hancock
Boa Hancock is the Empress of Amazon Lily and one of the former Shichibukai. She's an incredibly powerful character who got a bounty of 80 million berries after a single voyage with the Kuja Pirates, which just goes to show her level of fighting prowess.
Hancock is one of the very few Shichibukai who weren't scared or intimated by the Navy approaching them as she had full confidence in her abilities. Her newly evaluated bounty will likely be about 2.5 billion berries.
5 Marco
Marco the Phoenix is the former right-hand man of the strongest man in the world, Whitebeard. He led the First Division of the crew and has proved time and again that he's an incredibly strong character.
Marco was considered to be strong enough to stop Blackbeard from becoming a Yonko, which just goes to show how fearsome he truly is. His bounty will likely increase after Wano to around 2.6 billion berries.
4 Dracule Mihawk
Mihawk is a lone pirate who was a member of the Shichibukai until recently, just like Hancock. He is the world's strongest swordsman and although little is known about him, he is bound to be incredibly powerful.
He, too, wasn't scared of any of the Navy officers coming to capture him once his Shichibukai status was revoked, which means he is quite confident in his abilities. Mihawk's skill and reputation could give him a bounty of about 2.7 billion berries.
3 Luffy
The Fifth Emperor of the Sea, Luffy is the focus of the War of Wano Country and the man who'll likely make the biggest name for himself once all is done. Currently, Luffy has amassed a bounty of 1.5 billion berries, which is only going to shoot up further.
After the Wano war is done, Luffy could even be considered as one of the Yonko, and since two of the Four Emperors are involved in the arc, Luffy's bounty could shoot up to 3.5 billion berries.
2 Shanks
Shanks is one of the Yonko of the Sea who rose to this position four years before the beginning of One Piece. Being a Yonko, his strength is unparalleled and he's strong enough to take on any other power in the world.
He already has a bounty of over 4 billion berries, which could increase even further if, by some means, he gets involved in the Wano Country war.
1 Blackbeard
A Yonko with a bounty of 2.2 billion berries, Blackbeard is an unstoppable force that keeps on growing stronger with time. He's likely going to be the biggest villains in the entire series, and just like Luffy, he'll eventually rise to the top, although in a very different manner.
Blackbeard is already on the move and could end up getting the last laugh at Wano as well. If that happens, his bounty could very well shoot over 4 billion berries. We predict it to be about 4.5 billion berries.
