One Piece: The Search for Doraemon

The protagonist's imagination isn't big enough. Sharing fruits also includes sharing others' knowledge and power, but sharing pain is just too lame.

Doraemon can't find anyone?? I remember there are many kinds of gadgets that can be used to find people.

Why is Nobita acting like a simp? And that female Marine...

Doraemon's four-dimensional pocket and the spare pocket under his pillow are connected. You can go into the spare pocket and come out of Doraemon's pocket to find him. If the four-dimensional pocket isn't with Doraemon, then disregard what I said.

Doraemon

This is a One Piece fanfic disguised as Doraemon, but few of Doraemon's essential gadgets actually appear, and they're mostly in other people's hands without the protagonist's knowledge.

The subject matter is good, but why don't you write a story about Grey Wolf searching for Pleasant Goat?

The protagonist's abilities consume life force? I've only read a dozen or so chapters, but it seems like Red Peach knows the previous host of the Shared Fruit and has a book about developing the fruit. In one chapter, Red Hearts expressed concern that the protagonist was consuming too much life force, which was likely related to activating his ability.

Taking Zoro's sword is a bit off-putting.

I happened to come across this book, so I decided to take a look.
