Vivi and carrot are not comparable. Vivi whole character was always only about saving alabasta she was never meant to be a strawhats. And vivi is the diplomat? you are just saying that for one scene. Carrot not only trying to avenge pedro but she still have to learn about the dawn of the world and if Oda putting importance into that then it should have it meaning.
Also is oda trap to always use the same pattern? He can change the way he write the next strawhats.
The crew cried with her and help her with dealing with pedro death.
Carrot in retrospect to me even now still feels like support character rather than main character. In zou arc she wasn’t really character who had a lot highlights moment nor did she have a lot screen time devoted to her as her own individual. If anything you got more connected to the mink tribe in terms there ideals how they do certain things for others. As well showing there abilities what they can do.
In terms the tragedy in zou carrot was not really the Center of attention with in that flashback. In other words you didn’t see the pain or the lost coming from her perspective going on at the time. You just saw from pedro, neku, inu, and Wanda point view. By comparison she comes as a background character in that particular flashback. The only time she shows any interest going out sea is listening conversation with luffy, Nami, pekcoms, and Wanda about sanji.
In whole cake island arc she does appear to be stowaway on the sunny. We did learn little bit about her characteristics. In terms of her personality and what she wants to do. The only thing pedro says to us about carrot is “she is good fighter”. Carrot never says anything about her past before she met Pedro. You got to know more about pedro as a character as opposed to carrot in that arc.
Throughout whole cake island what did carrot actually do? She did save both Nami and chopper from being slashed. She end up teaming up with chopper to take down bruelee. She used her fan art regroup with other characters. She attempts to rescue brook alongside Nami, chopper, perdo, and Jinbei but fails do so. She does help nami, sanji, and chopper rescue the vinesmokes in the wedding ceremony. After, leaving whole cake island the biggest highlight she contribute is the suslong transformation. How much power wielded and it’s a drawback. After whole cake island arc she didn’t get any Notoriety or name recognition alongside with luffy, sanji, and Jinbei.
Through the course wano carrot hasn’t had a lot screen get know more about her background and her upbringing. In act 1 she was with half of the straw hats and reunited luffy and kinemon later listening to oden’s flashback from kinemon. In act 2 she was with rest minks barley shown while other straw hats were causing much rucks and a stir through out the island. Act 3 she is celebrating Jinbei arrival. The straw hats don’t even make a toast for carrot also joining the crew as another additional member. Ussop literally took over her role being look out by sense things from far distances. Carrot gets easily capture by one of big mom’s homies. Even though the original mission was going alongside with Nami to rescue momo as she said to kinemon. She does end up freeing herself alongside with Nami from that homie. She does indeed celebrates that Nami being save by Franky and Brook when big mom at time was about to kill Nami. She starts freaking out alongside with Nami when Franky ends seeing something similar to oars.
When the straw hats are doing there epic Fighting stance preparing for battle she ends going off own alongside with Wanda. She’s not really focusing on the main plot right now she’s focusing on her own personal grudge against someone else. So technically, she is not really working alongside all the straw hats at the moment or the minks. This is Something you would see from kyros or paulie would do.
We haven’t seen carrot since chapter 1006 that chapter didn’t even certain around her as character. If Carrot is “suppose to be the last straw hat” Oda is doing really poor job highlighting her importance and significant throughout this arc and raid that’s been going on right now. This raid has mostly certain around both Momo and Yamato as characters while Carrot feels like support character. Yamato getting screen time alongside with straw hats. She has even had chapters certain her as character. As right now Yamato at least doing something very important for straw hats survival. Without her being involved the straw hats would be dead right as result luffy second round. Right now in the story you are having Cat Viper who is going to end up fighting against Perospero. If cat viper is ends up defeating Perospero it would really undermine her own personal drive to join luffy in the first place. It’s very similar when Kyoros was fighting against Diamante. The aftermath Rebecca didn’t end up joining the straw hats instead she became ally to the straw hats cause. Same thing could happened Carrot as result.
