The Load Load Fruit is a devil fruit that allows the user to save their current self and then load one of those selves at any time.

Strengths and Weaknesses
This fruit's strength lies in the fact that the user can save and load themselves. For example if the user was at their peak of the day and feeling wonderful and full of energy they could save that version of them up to four times. They could then load one of those versions of themselves, brining back all that energy and spirit. If lost an item but had it with them they could load that version of themselves as well to get it back. They could also save up to four different sets of gear and switch them at will by changing what self they are. They can even delete damage to themselves by reloading.

There are downsides however. The user cannot reset things such as memories or skills, meaning that if they lose memories or skills they cannot get them back. They can also not create another save over a save that is less than 24 hours old.
