But when will you bring an example of a stronger character with a lower bounty than a weaker character?
But trolling aside, Mihawks bounty is proof that powerscaling is the biggest(not only but biggest) factor in bounties. Mihawks criminal actions pale in comparison to the Yonko,just compare Luffy, Buggy and Teach orchestrating an Impel down breakout, waging a war with the Marines, being bailed out by Shanks who stopped the head admiral in front of the world,while Mihawk worked for the government. Just compare all of the actions Shanks has done through the manga to Mihawk not doing much, and yet, Mihawk has a bounty near Shanks/Teach,being closer to Teach than his own *captain*
And Katakuri/crackers bounties are a terrible look for him, like it or not. We know that YC's get their bounties boosted from their captains, and Katakuris captain is known to wipe out entire countries for not paying her enough sweets. And yet, his bounty is still significantly lower then warlords who should have much less of a criminal record. Same with King/Queen who are globally infamous as "calamaities" and yet are lower then Croco/Boa
