The original argument was, "Jinbe fought alongside all of them. Carrot is fighting alone." Jinbe did not literally fight right next to every Straw Hat on Fishman Island. He still hasn't fought side by side with Usopp or Franky or Zoro. But both he and Carrot have worked with the crew before joining, fought on the same side, and helped each other out in a few independent fights. It's also not too late for Carrot to fight with Luffy or another Straw Hat on Onigashima, but again, I'm waiting to see what happens. .
Yeah, but Jimbei has work alongside Luffy more than just 1 arc though. He has done more significant things throughout his time being with Luffy as series as goes on. In other words, his character has done more important things for Luffy in his overall progress he made thus far in the series. Without him being there Luffy might have still been stuck in impel down or most likely die. Throughout entire series we have had with him he usually came as the voice reason and logic. As well a person who would help guide luffy towards his main objective at hand in those give those moments in time. In fishman island he would have an arc that would certain around him as character. In terms of his backstory and importance as character would be on full display in whole cake island. On top that Luffy has trusted Jimbei judgement and opinion on how to go about certain things multiply times throughout series. For example, focusing on rescuing ace, getting an escape ship, Luffy thinking about things he still has left, agreeing with jinbei to be hero in fishman island, going alongside with the idea to ally with the firetank pirates in order rescue vinesmokes, believing he will show up wano and recently agreeing with his opinion on saving strength against Kaido. He was also the most protective of luffy wellbeing and keeping him alive and his crew alive as well in whole cake island.
While in my opinion carrot still feels like support character just going along for ride to aiding and assisting the straw hats the best she can. If you had other minks came along with them at that given moment in time the situation would not have change. In some situation carrot was she was just there agreeing what they wanted to do. Her response is like alright, okay, gotcha, and I do my best. Her flashback does not tell anything more about herself. The only thing it tells us how she got her gauntlets. The biggest highlight of character was when she became suslong. What type powers it does. Possibly what role she might have her on crew. Once we land in Wano she did not do much anything with rest straw hats or luffy for that matter. When straw hats and their other alliance were heading onishima Ussop quite literally took her role of being lookout. She was originally supposed rescue momo alongside with Nami but she ends being easily capture by one of big mom’s homies. Later She had her own personal priority alongside with Wanda deal with perospero. Finally, throughout chapters we have been getting lately her fight was completely skip over rather getting attention it deserves.
I actually found the Franky scene had a lot of similarities to the WCI scene. Luffy asks Franky twice; first in chapter 416, then at the end of 418. The second time it's a lot more forceful, shouting Franky's name in a very direct manner. Oda took time to hammer in the importance of the moment, whereas with Yamato and in Dressrosa the way the orders were presented were a lot more perfunctory.
And again, it's not so much what he's asking them to do as it is why and how he's asking. On WCI, he's telling them that he'll be okay despite the danger ahead of him, and basically mirrored Pedro's command for them to keep moving onward. In Dressrosa, he's got half his crew staying with him and tells the other half to go ahead; the stakes are high, just like on Onigashima, but both moments had people already on it, and were not nearly as down to the wire as WCI when Katakuri was right there, or EL when Robin was about to pass through the gates. .
The comparison I was making between dressrosa and whole cake island situation was the fact in both situation they were in the direst. In both situation there were literally going up against big mom’s crew obviously and Luffy gave them direct order deal with situation go ahead without him. While he deals business somewhere else. You bring up two chapters that Franky being order twice by Luffy to look after robin. Your kind forgetting Yamato also had two-chapters in that similar situation. Luffy was the person giving her direct order to look after someone and as telling momo and Shinbou that this person is on our side. Let us also not forget both Franky and Yamato both put their bodies on the line in order protect those two characters at those moments in time. Her flashback had two chapters that had much greater detail surrounded her as character in comparison Carrot. With Yamato's flashback you got know how Ace and Yamato became friends, her predicament she was in, what she wants to do with her life, how she found about luffy, knowing Luffy hidden goal, and insert herself to plot with ace's virve card before luffy even met her. She has always wanted meet him for about 3 years. Indirectly asking him if she join his crew and wants to fight alongside with him. Luffy has already freed from her predicament. So she kinds own Luffy gratitude for doing such thing and defeat Kaido raises possibly of her joining Yamato still might have past that is worth showing since she has mention to luffy and momo about it before. It's likely we going get to know more about it. In terms presentation wise yamato still has a lot offer in terms her power and still has hidden ability that we have not seen from her just yet. So far since act 3 of wano this has certain around her as character alongside with momo. Presentation wise she look better than carrot does in her base form in terms fighting capability and getting to know little bit about herself on personal level while carrot by comparison still feels like she is kind lacks story to tell the audience.
