Here I see for those who all will participate in it on their bounties, but more so for those pirated or leaning on it:
STRAWHAT PIRATES:
Straw Hat Monkey D. Luffy - 5,500,000,000 Billion Beri (He be taking out probably a Calamity and then Kaido himself as well causing mayhem in Wano, his bounty would increase like this, but then again Idk what's Kaido's bounty, so his bounty would rise to be above or equal to Kaido's bounty, so might make a change to this and maybe to the other bounties when we get a reveal on Kaido's bounty).
Vinsmoke "Black Leg" Sanji and Roronoa "Pirate Hunter" Zoro - 2,500,000,000 Billion Beri Each (Knowing Oda and how he likes keeping a rivalry between them as he already showcase it many times. Plus with their potential opponents in Wano (King, Queen, Jack, or Orochi), it would make sense why they both get huge increasion respectively. Plus I can truly see Oda making them tie with their bounties to help stir their rivalry more and probably the communities as well XD).
Tony Tony "Monster Raccoon/Tanuki" Chopper (Nod to you, Zetsu for your title) - 1,000,000,000 Billion Beri (Yep, from 100 to 1,000,000,000 in a instant lol. I can feel that with Chopper, he would be 'Usopp or Buggy' on how he get his bounty and reputation, but more legit since he probably play a role like Zetsu said and it being a theme Zoan DF User arc with Kaido's crew. Can see him helping out as a doctor and also fighter too with perhaps higher-ups in this. Maybe even against Jack (I am kidding....Or am I XD?!)! Regardless if it does happen, we can see the Government finally take Chopper seriously since they are coming to Wano early on and see his power instead of looking him as just a pet/mascot to the Strawhats. However, I feel they would confuse him as a "Raccoon" in his new title than Reindeer since that a running gag on him too or even mistake him for a Tanuki as well XD).
Knight of the Sea, Jimbei - 896,000,000 Million Beri (I feel it be more affiliation than doing 'heavy' stuff in Wano as I envision him coming late to the party compare to the others are doing, but if Big Mom will be there, he could handle one of the Sweet Commanders and maybe other higher-ups to get his increasion more).
God "SogeKing" Usopp - 500,000,000 Million Beri (All Hail God Usopp/SogeKing! He be the one to bring Kaido to his knees and everyone else XD! Lol, but seriously I do see Usopp shining and be somewhat legit of his power and strength especially now he has Haki, but do see half of it could be part of his 'hype' as God Usopp when he does thing inadvertically into helping others and maybe even defeating his opponents, so could see it rising by combination of the two).
Iron Man Franky - 444,000,000 Million Beri (Congratz on Franky finally reaching over 100 million mark, but sadly I feel they will do him dirty by having him still under God Usopp and still not using his real appearance and still his Franky Shogun which make sense due to the theme in Wano and "Shogun" lol. I can see him going in and fighting with higher-ups left and right as seeing how he didn't like the treatment of the Tottas and factories, pretty sure Franky would be angry again on the people of Wano treatment on 'lesser class' and factories being another part of cause for them. I can see him going to destroy all the factories (With help of course) and face higher-ups in the process with one of them being "Iron Boy" Scotch, the one who faced Drake X. Lol, Iron Man vs Iron Boy, who would going to win (Franky obviously).
Nico "Demon Child" Robin - 350,000,000 Million Beri (Robin will probably get a moment to shine in this arc since she be trying to attend Orochi's inner circle and probably to Kaido's higher-up group as well. She is bound to get into a fight with others and especially uncovering Road Poneglyph in that wake with the others as she is the only one to decipher them. So yeah, hope to see she gets a serious fight with her since it been a long time since we got one with her).
Soul King Brook - 330,000,000 Million Beri (After his performance in WCI, pretty sure we going to expect more in Brook in this, but don't be so sure or put your expectations too far off as while he did have achievements in getting the objectives, his combat is another story as he was having trouble handling higher-ups in moments, so I don't expect him beating anyone so higher up, but he can take on many Headliners and maybe someone close to Calamity, but that's stretching a bit. Though with his power of music to 'soothe the savage beasts' as the saying goes and swordsmanship to add on especially for Wano to showcase to others, I feel he would get a significant amount raise to him and able to cause trouble and mishap especially looking like a undead, ghost warrior...Oh, but he is already undead warrior. Skull Joke YOHOHOHOHOHOHO!!!).
Cat Burglar Nami - 227,000,000 Million Beri (Despite might be lowest bounty of the crew and that is a "If" unless Chopper is still treated with the low bounty still, I can still Nami doing work in Wano as shown in the previous chapters with her a Shinobu, she could play somewhat big role in helping everyone. Plus with her Zeus power-up, she can do more damage than before and maybe take on a higher-up for her to beat after a long time. Maybe one or her final opponent could Ginrummy if she proves to be a real threat as you never know or loyal Shinobi/Kunochi or both against Nami and her Shinobu. See big things on what she can accomplish with her potential).
This is my prediction for the group atm and will add onto the allies later when I get the time
