Unfortunately, it won't be Loki. Imo, he will lead the giants crew as a subordinate to the strawhats and maybe together with his brother. A duo captain like Dory and Brogy. They have been demonized and would probably die or become an enemy for a while. Vivi has too big of a role to her kingdom, so there goes that. Bonney = daughter of Kuma who is from the revolutionary army who knows Nika and has talked about him since until now. It's really pointing to Bonnie at this point. But who knows, maybe Oda will surprise us.
