WMG / Marie D. Suesse And The Mystery New Pirate Age!

Someone will, in canon, have a bounty even greater than Madelyn's
Considering that Kidd's bounty is already 470 million, well above Slashfang (401 million), Hana (419 million) and the nameless 444 million berry bounty head the Disinfector defeated, it's likely that someone's bounty will be above that level. My prediction is that any of the following are likely candidates for topping Madelyn's bounty.
  • Luffy after his next one or two bounty increases.
  • Whitebeard, posthumously.
  • Blackbeard
  • Kaidou, Big Mom or possibly Marco, as a way of showing how much stronger the Four Emperors are.
  • Dragon, the canonical most wanted man in the world.
Confirmed. Jack did.
