Yes, there are. There are many fan - created stories that involve Zoro, Robin and Chopper. Some might focus on their adventures together on the Thousand Sunny, like how they work as a team to overcome challenges during a battle with a new enemy. These fanfics can really show different aspects of their relationships that we might not see as much in the original manga or anime.
You can try fanfiction websites like Archive of Our Own (AO3). It has a large collection of One Piece fanfics, and you're likely to find some great ones featuring Zoro, Robin and Chopper there. Just use the search function and type in their names.
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.
I'm not entirely sure what this specific phrase means in the context of fanfiction. 'Anaconda' is a large snake, and'strangles' is a rather violent action. It could potentially be a very strange or dark fanfiction concept, but without more context it's hard to say for sure.
No. It is not a common type of fanfiction at all. Most fanfiction focuses on relationships between characters from existing works, or on exploring different storylines within the established universes. The idea of an anaconda strangling the reader is very strange and not something that typically falls within the normal themes of fanfiction.
Strangles might be a scary disease or condition in a children's story. It could be something that the characters have to overcome, like a sickness that has befallen the animals in a magical forest. For example, the brave little fox might set out on a journey to find a cure for strangles that has affected his friends.
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.
