I found a numerical Pattern in Luffy and Zoro Bounty.
Luffy FIrst bounty - 30,000,000 (30M berries)
Zoro at that time - 0
luffy Second Bounty - 100,000,000 (100M Berries)
Zoro FIrst Bounty - ( 2 x Luffy Previous Bounty + 2 x Zoro Previous Bounty )
- ( 2 x 30 M + 2 x 0 )
- 60 M berries
Luffy Third Bounty - 300,000,000 (300 M berrie)
Zoro Second Bounty - ( Zoro previous Bounty x 2 )
- 120,000,000 Berries (120 M Berries)
Luffy Fourth Bounty - 500,000,000 (500 M Berries) I'm only including where the whole crew got a Bounty upgrade not just luffy
Zoro third Bounty - ( 2 x Luffy Previous Bounty + 2 x Zoro Previous Bounty )
- ( 2 x 100 M + 2 x 60 )
- 320 M berries
again wci only luffy and sanji got bounty hike not the whole crew.
luffy bounty post wano - 5 Billion probably.
zoro next bounty - either it follows this pattern of
- ( 2 x Luffy Previous Bounty + 2 x Zoro Previous Bounty ) with either 500 M or 1.5 B one
- So either 1.64 Billion or if we take 1.5 B in the pattern then 3.64 Billion bounty.
I know the the pattern is inconsistent but it also follows the pattern of this numerical pattern being used one after another , and remaming time it was just double of his own current bounty. so we can expect Zoro Bounty to be 640 Million berries if he was in Whole cake island.
also I do expect zoro to get a bounty of 1.6 B after wano.
and if this time zoro threat is actually analyzed , He may get buffing bounty of 3.64 Bounty which highly unlikely. but oda gave zoro adv conc and so far only top tier characters have used This like rogers, whitebeard , bigmam , kaido and luffy. and yamato too.
zoro usually surpases his last opponent in a battle. this time he defeated a yc1 and i expect him to either equal to yonkou post next arc or jsut below him. and zoro gets absolutely no reason to deal with Yc1 anymore. his should aim for better. we all luffy 1.5 bounty was buff more than he deserved. 900m to 1.1 billion would have done the work but it got inflated high due to morgan. maybe gets final arc some momnet like god ussop and ends up with a bounty 3.64 billion zoro current threat is that. above a yc1 below yonkkou.
but he is most likely to get 1.64 B as his bounty.
