why people get upset over jinbe's bounty but not on crocs?
Because Croc is involved in something completely different than Jimbei.
Jimbei‘s bounty increase is based on what he did in Wano and we have 2 other SH‘s that did way more than him yet are below him or barely above. His huge bounty increase doesn’t make sense. All he did was defeat a 560mil Toppi Roppo, while the other 2 defeated YC‘s worth over 1.3bil.
The ‘‘he was a Shichibukai so he also got a increase for that‘‘ argument doesn’t work here since he is not a Shichibukai for over 2 years and didn’t get this ridiculous boost.
Robin defeated a TP with a 480mil bounty, she did something comparable to Jimbei. But her boost to 930mil is because of her knowledge and past. Jimbei should have been above Robin, because he defeated someone stronger and already had a higher bounty than Robin (Robins boost not included) - in around the 700mil range. Based on achievements Robin would be below that at 500+ to 600+mil. And honestly there would be nothing wrong with Jimbei being below Robin because of her boost, that atleast would be based on something, not like now.
There is honestly not a single logical reason for Jimbei‘s high bounty besides, make him above Robin and make a gag scene with Sanji.
Crocs bounty increase is based on his alliance with Mihawk and Buggy and their Marine hunting organization.
