Gocha Gocha no Mi in One Piece

As the fruit hasn't yet been shown in the anime, we don't know a lot about its appearance.

An advantage of this fruit is that once the user merges with someone, they can grow huge in size and strength. They can also fuse with inorganic objects. This can be seen when Charlotte Newshi merged with Charlotte Decuplets.

This devil fruit isn't quite handy to the user if they don't have anyone to merge with them. Other than this, it has the standard devil fruit weakness that other devil fruit users have, i.e. that they cannot swim.

Charlotte Newshi uses his devil fruit power to merge with his nine siblings. They turn into a giant creature which wields a very large Scythe, which also increases their fighting abilities.

The techniques used by Newshi are:

Gattai

In this technique, the duplets stand in a formation next to one another and then Newshi activates his devil fruit power to fuse all of them together to form a giant with a Scythe.

Q. What does Gocha mean?

A. Gocha translates to ‘mixing things in a disorderly way’.

Q. What is the devil fruit’s weakness?

A. The disadvantage of this devil fruit is that it isn't useful to the user if they don't have anyone to merge with.
