Gyaban was really impressive. I didn't expect him to get up and still ready to fight again with only one arm. This guy is a demon. Unbelievable character with both personality and top strength. The fact that he is fighting for Elbaph makes him really an honourable and dependable guy.
Harjudin did really good. He already displayed great physical strength in Dressrosa and again here. I could feel the impact of that punch and Imu got sent flying away. But let's be real, the damage to Imu was pratically zero.
Luffy seems like is back on his feet. I admit it, his stubbornness is starting to annoying me. In the latest chapters he did show a very pitiable spectacle not gonna lie. But I guess it's in unfortunate conditions like this that he is able to create some kind of miracles. I expect some power up from his devil fruit (I want to go against the tide, when one would expect a supreme king haki power up considering how important it is in Elbaph).
Oda is giving everyone something. But this should not be taken as an Imu downplay, on the contrary, he is fighting all by himself against a continuous streak of opponents and he is faring really great considering he is also not at 100% from the start. The new transformation is pretty cool even if I prefer the first one. He is gradually becoming more demonic, the fruit of the devil nonetheless.
What Biblo said to Chopper, I feel is something about Elbaph and how the time is perceived different here. Biblo is a very misterious character, I expect some big reveals from him.
