Many strong possibilities. I feel like Shanks and Blackbeard are the most likely, since I don't what place would exist for either of them at the end of the series, but who knows what Oda will do.
I hope Perona doesn't die, though her DF would be an interesting one to add to Blackbeard's crew.
Yeah I'd hate for Perona to die and become closer to a "ghost" to speak, horohorohoro BUT I did suspect her DF would work nicely with Van Augers sniping potentially (ghost bullets that can go through walls for example and depress their targets, making them unable to fight back too) but someone just suggested Doc Q might get her DF and that sounds pretty logical and likely too.
I actually really wanted to see Corazons silencing DF return for Auger as I think it would be EXTREMELY dangerous/lethal on a sniper, never knowing where he is firing from as you cant hear the gunshot and have to rely on situational awareness and especially CoO to try and survive without sound to help you? Imagine if his bullets can be silenced so if they hit you, you cant even scream and be heard? "In silence/my vacuum, nobody can hear you scream"
Tokis DF needs to return somehow too, I wonder if BB would hunt it down too, surely he would find a use for it, a DF that can actually manipulate time? He would know the full potential of it and thus its true power too?
Yeah, I really dont know what Shanks and Blackbeard would do post EOS, I think this is why Oda killed off Kaido and BM too. All the former generation may die, as in the Yonkos but Im not sure if Rayleigh will outlive Shanks lol. Its possible but it would really suck for him.
Marco has LOST so many people now, so many beloved people, that I feel Marco being a phoenix too, has massive death flags and would love to finally rest and reunite with the people he lost in death/an afterlife even ideally or even to "reincarnate" into a new life, like a "phoenix" lol. Start over.
I honestly didnt expect Izo to die, that was quite random and infuriating for me. I was worried Kiku may die and I expected Ashura to die as he had massive death seeker vibes since he appeared. Im conflicted on Kinemon actually surviving too.
I fear whoever kills next and he will kill more definitely, thats a given, its gonna be real emotional gut punchers once again. I think for that reason, Garp will be a big one as I cant see his character surviving to the end and having a role post EOS plus he and Roger were the guys who took down Xebec and thus the guy who Blackbeard seems to idolise and follow the will off. BB must want revenge on him, for killing his hero.
