There are no limits in the world of One Piece.
For years, many fans have speculated about the future destinies of the Straw Hat Crewthereby giving rise to talk of all kinds of islands that the main characters of One Piece could visit, which has even led many to theorize with the possible arrival on the Moonthis being something that should not be surprising if we take into account all the eccentricities of Oda, mangaka of the license, throughout all this time.
Now, what at first seems like the craziest theory of all, it seems that could gain strengthsince it cannot be overlooked that our natural satellite plays a very important role in the One Piece lore, either because of the Lunarian tribe, because it is in the background in relevant scenes, among other moments that it has given us.
Luffy’s crew could have an adventure on the Moon

Trafalgar Law and Luffy have become great allies throughout the series. However, they are also rivals, as both are in search of One Piece.
Under this premise, it should be noted that the scriptwriter of One Piece Film: RED, Tsutomu Kuroiwa, has spoken about what making this film has involved, noting that Oda at the time commented that you could do anything with One Piece and his world, including here the chance to go to space.
In this way, it can be seen that One Piece is a story that allows you to do anything, thus giving rise to the need to see the way and the way in which they would justify the fact that pirates can go to the star, especially knowing the laws of physics. However, with Franky on the team, it cannot be ruled out that it turns the ship into a rocket.

Be that as it may, we will have to see what ends up happening, since with the final arcs in publication it is not known if there will be time to go to space, since there are too many open plots, such as Kuma’s originwhich still need to be resolved.
