“Kid being able to his Apoo means his haki shuts on Luffys who was knocked out”
How does this even make sense…
Your analogy doesn’t even make sense, Kid was still damaged by Apoo’s powers.
Saturn only let Bonney stab him because she was a fodder. He absolutely shut down Sanji, preventing him from doing anything. Yet he somehow let Kuma take one of his legs off? Doing enough damage to undo the hold Saturn had on the SHs?
Nah, Kuma has better haki portrayal, there’s no way around this.
