Is fan fiction always based on existing works?

Mostly no. Anime can have diverse sources of inspiration. Some are based on comics, but others might come from light novels, or be the brainchild of the animation studio itself. It's quite a mixed bag.

My story is completely original. I came up with all the ideas and plotlines myself.

There may not be a well - known body of work directly named 'shakespe science fiction'. But think about it, a science - fiction story that retells Hamlet in a space station setting could be considered part of this. The prince's struggle for revenge could be paralleled in a story about an astronaut seeking justice against a corrupt space colony leader. It's possible that such works exist in the realm of independent or experimental literature.

I'm not aware of many works specifically called 'ape pulp fiction', but there are some that might be similar. For example, some old - fashioned adventure stories about jungle - dwelling apes or primates could have elements of pulp fiction. Tarzan stories, to an extent, have that pulp - ish feel with the wild settings and action - packed sequences, and they involve apes as part of the story.

Yes. 'Rosencrantz and Guildenstern Are Dead' by Tom Stoppard has elements of both. It takes minor characters from Shakespeare's 'Hamlet' and places them in a sort of absurdist, quasi - science - fiction - like world where they question their existence and the strange events around them.

I'm not sure if there are specific works directly titled 'Rugrats Science Fiction'. But the Rugrats franchise could potentially have some episodes or storylines with science - fiction elements. You might want to check out some of the more imaginative episodes where they have out - of - this - world adventures.

Not necessarily. You can create original fanfic or be inspired by existing works, it's up to you.

Yes, there might be some. Some authors might have taken the basic concepts of pride and prejudice and put them in a science - fiction setting. For example, they could use the idea of different factions in a sci - fi world having their own forms of pride and prejudice towards each other, similar to the social classes in the original novel.

Not necessarily. Fiction often takes inspiration from real-life elements but can also include completely imagined scenarios.

There's a lesser - known novel called 'The Nine Worlds' which does an excellent job. It takes the nine realms of Norse mythology and turns them into different planets in a science - fiction universe. Each planet has its own unique ecosystem and culture, based on the original Norse concepts. The main character, a human astronaut, gets stranded in this universe and has to navigate through the politics and power struggles of the Norse - inspired planets using his scientific knowledge and wits.
