@Shiebs:
I’m not saying it’s impossible for him to join, just that we should wait for an interaction with the crew
Also does his DF fruit fit the 2.9 theory
No, but I personally believe that its the fruit itself that is going to join instead of a whole person with a fruit.
and Kuma's biologically dead, I wouldn't doubt a bit Vegapunk extracted his devil fruit at some point. specially since we haven't seen Kuma using it since the time skip.
And Oda said he made the Supernovas up really quick and on the spot to make Sabody arc better, doesn’t sound like a straw hat, that have been planned from the start or soon after, same reason Many think Bonney wouldn’t join up
Their concepts have definitely been in Oda's head for a while already, its their designs that supposedly came up on the run, but that's funny since each of the Worst Gens have a much better detailed design than Carrot will ever have.
X as in 10 as in the tenth straw hat
Dude what??, his name is literally Diez Drake, Diez is ten in Spanish, he uses it as X(roman numeral for 10) for reasons we don't know yet, but one good reason of why I think he uses it like that, it would be that he doesn't want people to recognize him as Diez Barrel´s son. since you know, Barrels is a shame to The Marines and stuff.
And his name "Drake" comes from Sir Francis Drake, literally the second person in history to have circumnavigated the world, just Like how Luffy is going to be the second person to ever reach Laugh Tale.
