I think the role thing is a bit to overused. Robin is an archeologist, that’s not a role on a ship. Maybe he’ll have a hobby that will turn into a role, like the crew’s photographer or something lol.
With Wano, Weevil, and then Blackbeard, as you mentioned, Marco is going to relevant with the crew for a long time, which only increases his chances.
I think Marco will join after helping them fight Teach. Luffy vs Blackbeard, the other nine vs nine of the titanic captain, and then Marco vs the last one, whoever that may be. So he’s not only going to witness it in my opinion, but be an integral part of it.
Yes, I will, because Hawkins has more relevance to Kaido, Drake is a marine, both are captains, and Zoro is far too weak. Zoro has zero relevance to Kaido. Enma’s significance was negated the moment that it was revealed that Enma was not the only sword to cut Kaido, because Oden used two swords. It was not Enma that cut Kaido, it was Oden. Zoro holding Enma does not mean that he is as strong as Oden. He also has no “superiority” over the scabbards, whatever the blue hell that means. Beyond that, It is idiotic to suggest that Zoro will go from fighting Pica and then drawing Killer to fighting Kaido.
For future reference, Zoro is my second favorite character. I’m just not looney tunes like the Zoro fanboys that infest this site, and apparently because I choose to be more even about Zoro, it makes me a hater. Don’t quote me with this nonsense again.
