I drop my prediction about how the fight between Killer and Hawkins will go on.
So I think that Killer will somehow trick Hawkins.
Let me clarify: I think you all remember Sasuke vs Danzo.
Basically Danzo was spamming Izanagi since he had 11 Sharingan on his arm, but Sasuke tricked him and deceived him into believing that he still had 1 Izanagi left, which of course wasn't true.
What will Killer do?
I feel that he will trick Hawkins making him think that he still has Kidd's doll.
We will see Hawkins being overconfident and tank Killer's attack thinking that it will hurt Kidd...except for seeing that the person being damaged is none other than Killer himself.
So at this point Hawkins will be left without any hostage card to play and a nerfed Killer will beat him, and in this way 3 things will be highlighted:
-Killer's smartness. I don't know how he will trick Hawkins but he's a very knowledgeable and I think that he knows what is the weak point of Hawkins DF since he also knew the weak point of Apoo's DF, which was the other member of his alliance
-Killer's loyalty and his sense of self-sacrifice in order to protect his captain/partner
-Killer's endurance (btw don't forget that he tanked Fulgora better than Kidd)
