The most interesting part of Chapter 1008 is the conversation between Yamato and Momonosuke. Specifically, the part where he seems to have some degree of awareness of what’s happening to Luffy on the roof of Onigashima.
It seems there are a few potential implications here. We learned one chapter prior that Momonosuke’s artificial Devil Fruit was made by Vegapunk using Kaido’s genetic information while Kaido was in captivity. Perhaps this implies that Momonosuke’s artificial Fruit is innately connected to Kaido’s if the foreshadowing on Enies Lobby turns out to be real and there is some living / soul component to Devil Fruit or some living entity residing within Devil Fruit.
We also know that there is only one of each Devil Fruit and perhaps there’s a deeper reason for that of which we are yet unaware. Maybe the fact that Vegapunk made this fruit from Kaido’s means they are inherently connected. Maybe there is some type of unbreakable bond connecting the artificial fruit to the original from which it was derived. In this case, the artificial fruit would not be distinctly its own thing.
I have said in the past that I believe there is some good luck or good fortunate component responsible for Kaido’s long survival. He’s not unbeatable, but he is unkillable, and as an Eastern style dragon, I think there’s a good fortune factor at play here. Momonosuke, possessing not just a similar fruit, but the same fruit, could reinforce the notion that Momonosuke is the key to ending Kaido’s winning streak.
Of course, this is not the only thing this scene could be implying. Momonosuke could simply have some advanced Observation Haki or this could be hinting toward a power belonging exclusively to his artificial fruit, disconnected from Kaido entirely. It’s just interesting to consider the possibilities here.
