Well, 'chopper fanfic' is basically fan - made stories that revolve around the concept of 'chopper'. If 'chopper' is a vehicle, like a motorcycle (which is often called a chopper), then the fanfic could be about cool rides, customizations, or races involving these choppers. It all depends on what the 'chopper' in question represents in the context of the fanfic.
No, in the traditional sense, Chopper, if you mean the character from 'One Piece', is a reindeer and doesn't have the physical ability to read novels as humans do. However, in a more imaginative or fictional scenario within the One Piece world, perhaps with some magic or special ability, it could be possible, but there's no such indication in the original story.
Hard to say. It could be associated with a minor character whose background wasn't fully explored. Or perhaps it was just a random prop without a specific owner.
Yes, Chopper might like to read stories. Maybe he likes adventure stories as he is quite an adventurous character himself. Stories about exploring new islands or facing big challenges could be his favorite.
For Nami, her intelligence and cunning are key. She could use her smarts to get Sanji out of trouble in the fanfiction. Also, her love for money and treasure can add an interesting dynamic. For example, she might convince Sanji to go on a dangerous adventure in search of a valuable item, promising him new ingredients for his kitchen.
