Hopefully, the Fire Tanks and Germa 66 will find some way to get out of that mess intact. I don’t know what that Cake is supposed to do, or what Pudding said to Sanji, but either should be something useful to lay things for an eventual round two or whatever at either Elbaf where we’ll meet Gerth and Loki among others, or maybe even Linlin’s original homeland where we could meet any “probable” siblings and their offspring of Linlin’s. Either option could be symbolic of her preferred final defeat. As for the New Giant Warrior Pirates, I hate to bet that we won’t see an older Gerth for a while, but from what I’m seeing, the most common Elbaf warriors are men, and I actually have seen some information that Eiri will be the crew Helmsman, which probably will be a given if the anime decides to show him in some manner in the Elbaf flashback.

However, about two chapters ago, I did speculate that we might’ve seen Gerth back in Part 1 as the sole female of the Marine Giant Squad, which might be indicated in the coming flashback if she’s given blonde hair and blue eyes, if not confirmed in the possible Marine reaction to the events in Totto Land in a near future chapter. How she could’ve become a Marine without being trafficked by Carmel would probably be the result of Elbaf’s seeming lack of military action against Big Mom if she does indeed hate for all the bad stuff in the past, or maybe she doesn’t hate her enough for that and got tired of living in a country that curses her name without actually doing anything about it. To be honest, I do try to be flexible, but if Ryokugyu isn’t a woman and Isuka from the novel doesn’t appear in the main story, I would like to see the female Giant Squad member either have a good role in the future, or be the same person as Gerth and have an important role still for the sake of Marine Luffy AUs. I’ll have to see how it goes.
