Hako Hako no Mi

The Kyubu Kyubu no Mi is a Paramecia-Type Devil Fruit that allows it's user to somehow force people to fold themselves into cubes either through touch of by being in the general area of the user, making the user a Cubing Human (HELP ME WITH THIS PLEASE!). "Ubu" comes from the word Kyubu, which is Japanese for "Cube". In translation it is called the Fold-Fold Fruit. It was eaten by Yatsuomote, one of the Reckless Generation.

It's power was first seen during the Sabaody Archipelago, but was not named or explained in any way until sometime after the timeskip.
