What other types of islands will the straw hats visit in the grand line?

[Splat]

Just for a quick reminder of which islands we have already seen in the grand line:

Whiskey peak baroque works island, Little garden the giants island garden, Drum island the winter island, Alabasta the desert island, Jaya the remaining half of skull island, Skypiea the sky island, Long ring island the ring island with several different connected islands, Water 7 the shipwright/waterway island, Enies lobby the marine judicial island, and currently Thriler Bark the giant ship/graveyard type island.

Also as we know, the straw hats are on their way to an underwater island after this current arc.

So my question is what othe types of islands do you think they will visit? I personally think that there will be an island in the middle of calm belt, that will require a reworking of the thousand sunny, with seastones, to allow them access.

Also as a related question, what do you think, Raftel, the last island in grand line will be like?

Well Buggy has been shown to be on Raftel. But he was digging tunnels underground because he was too scared to be on the surface of the island...

I'm guessing there are really strong people or monsters on the island. Either protecting One Piece or trying to get to it too.

I hope they run into a futuristic island or something full of robots and space cars like the jetsons lol. Maybe get to the Moon somehow and fight Enel to the finish.

I want to see the end of the islands, where Gol.D.Rodger visited last, also the land of the giants would be quite funny to watch.

An island of musicians would be interesting, but useless since they already have Brook.

I believe the last island will really be some sunken island like Atlantis where the true history happens to be. Also, there will be some sort of island where they have to split into different teams to explore. Or maybe I'v been playing too much Skies of Arcadia ^.^

 

[Impel Down]

Well, Mermaid/Fishman island are both submurged underwater, and they split up into teams in Skypiea.

 

[Helltroll]

well...elbaf would be real cool and is neccessary 2 (not only for ussop). also mermaid/fishman island will be real nice and another atlantis like island (maybe the last island on the grandline). then we will have the hq of the marine and the hq of the rebels....and i think this is quite ok for at least another 300 chapters....

 

[smellyCheese]

No,, the last island in the grand line is the place where Gol.D Rodger was last, and it is a definate island.. not a sunken city..

 

[OP_overlord]

the mermaid island is going to be awsome but they arent going to fit jembie cause they just fought gekko.

elbaf is going to be closer to the end of this tale
the revolutioist HQ will also not be until later, and they arent going to go to the WG HQ the WG will come after them when they are chillen with dady monkey at his hide out. (they just had the enels lobby arc and the WG doesnt want them to be on the offensive again.)

i have more ideas but that is for a later time
