Too much is put into bounties in terms of value.
All a bounty value means is a character has committed x amount of crimes to get that value.
Luffy's 1.5 billion bounty =
- East Blue saga crime/incident 30m
- Alabasta crime/incident 100m (70m increase)
- Enies Lobby crime/incident 300m (200m increase)
- Sabaody, Impel Down and Marineford crime/incident 400m (100m increase)
- Dressrosa incident 500m (100m increase)
- WCI Incident 1.5b (1b increase)
It took Luffy 3 incidents/crimes to achieve a bounty of 300m in a year.
If you don't know the crimes a character has committed and the magnitude of the crime or incident, it's almost impossible to really estimate bounty.
There is almost no such thing as a character have a bounty that's too low. Why? because a bounty only reflects the magnitude of a pirate's criminal activity.
And all bounties tell a different story.
Caesar has a 300m bounty, for what, defeating the most powerful Pirates? No, he just blew up a base of scientific operations with a biological weapon.
Robin had a bounty of 80m simply for being able to read Poneglyph.
We shouldn't be so rigid and assume bounties only have 1 meaning. Bounty values only have a meaning if we understood why they were attributed. A bounty of equal value doesn't necessarily mean the same thing.
Robin (age 8 and weak) had a bounty of 80m for Ponehlyph reading whereas Boa Hancock (user of all 3 forms of Haki) had the same bounty of about 80m for a pirate campaign. 2 different crimes resulted in the same bounty.
When we look at a bounty, we should be thinking how many crimes has this person committed and what were the crimes? Bounties tell a story.
Like
@JazzMazz said, most Big Mom Pirates probably have bounties around the 100m mark, and he/she is probably right. Why? The majority of Pirates are not out there destroying WG facilities or breaking into Impel Down or participating in the War of the best. The majority of them probably just do petty crimes compared to what the Worst Generation Pirates do, thus why most would be low valued bounties numerically.
Also, don't mistaken a bounty being higher than another meaning more dangerous.
Caesar got a bounty of 300m for being in possession of biological weapons and on top of that, he can make Devil fruits. Who else has a similar or higher bounty, Bege. Who is the more dangerous between Caesar and Bege? Caesar by miles. Caesar's scientific value makes him much more of a threat.
With that said, even though Robin has a bounty of 80m, she's probably the most dangerous individual in One Piece because whoever possesses her has the power to rule the world because:
- She gives access to Ancient Weapons
And even worse than that, she's the key to Laugh-Tale and anyone who gains access to Laugh-Tale gets access to Knowledge. As they say, Knowledge is power. Truth is power; anyone who can expose the truth of the WG will gain the backing of the world and essentially, whoever has the backing of the world rules the world.
There's a lot more interesting things and details than bounty value. I see a bounty, I'm more interested in what exactly did they do to earn that bounty?
Urouge was only 108m in bounty. Did he get that from 1 crime? If so, what did he do? There's lots more to bounties than strength.
