I believe that at the end of the Wano arc, Luffy’s bounty will be even bigger than Kaido’s and Big Mom’s current bounties. It is apparent that the Five Elders greatly fear Luffy’s potential and even ordered CP0, the highest agency within the World Government, to eliminate Luffy as he battled Kaido, due to the risk of him winning and disrupting the balance of power in the world.
This fear was so great that they were more than willing to anger Kaidou and sacrifice one of their top agents in the process. One of the primary reasons they fear Luffy is because of the true nature of his Devil Fruit power, which when awakened, will grant him “the most ridiculous power in the world”.
I’m guessing credit for beating Kaido and Big Mom is going to be split between him, Kid, and Law. Luffy will get the lion’s share of the credit, since he defeated Kaido alone and Big News Morgans will likely claim that Kid and Law were working for Luffy, but I figure Kid and Law’ bounties will also undergo a huge increase since together they have defeated Big Mom.
My guesses are:
- Luffy: 5 Billions
- Eustass Kid: 2.5 Billion
- Trafalgar Law: 2 Billion
- Nico Robin. Robin’s greatest threat is always from the World Government, since, from the age of eight, they have ruthlessly hunted her. The persistence of the World Government and their view on her being a threat would not cease even after a timeskip passed, as during the Raid on Onigashima, the World Government send numerous ships out to Wano, openly to annexing Wano under the World Government, but secretly having a second order for its agents arriving there with the capture of Robin, still seeing her as a threat to the Government and the secrets its trying to withold from the world. This order was later seen being put into action, when some CP0-Agents chased Robin and Brook in the castle, with Robin wondering why the CP0 was in Wano and her being unaware of her being still a thorn in the eye of the Government. I could see Robin getting something absurd like 1.5 Billion bounty.
- Zoro: 1.4 Billion. He’s the right-hand man of the current 5th Emperor. He has defeated Kaido’s strongest Commander. I can see him gaining a slightly higher bounty than King.
- Sanji: 1.35 Billion. Slightly less than Zoro, slightly higher than Queen.
- Yamato: 1 Billion. This is just a guess, and it’s absurdly high for a first bounty, but depending on what Yamato does or how public that knowledge is, I could see her getting a high bounty for being the child of an Emperor and Strongest Creature, and betraying that Emperor to join the Straw Hats if that’s what winds up happening.
