One interesting concept is the exploration of different character relationships within the human zoo setting. For example, how the gems interact with the humans they've captured. Another is the potential for human resistance or adaptation in such a strange situation. And there could be the discovery of unique powers or knowledge that the humans gain from being in the zoo.
The original Steven Universe series has themes like identity and self - discovery. In the Human Zoo fanfiction, this can be taken further. For example, the humans in the zoo might question their own identity as captives and start to discover new aspects of themselves in this strange environment. Also, the theme of power dynamics is interesting. The power the gems have over the humans in the zoo can be explored in depth, compared to the power relationships in the original series.
In the context of the show's universe, it's a bit of a strange concept. Since fanfiction exists in our real - world fandom and not in the show's world directly. But if we were to imagine a meta - situation where he could access it, I suppose it could be possible. However, it would be a very surreal situation for him.
Another idea is a human OC who is a detective in Beach City. They start to notice strange happenings that are related to Gem activity. As they dig deeper, they get involved with the Crystal Gems and become an ally. They could use their detective skills to help the Gems solve mysteries, like finding missing Gem shards or uncovering the secrets of an ancient Gem structure.
In a fanfiction where the Gems turn human in 'Steven Universe', they would likely experience a whole new set of emotions and physical limitations. For example, they would no longer have their gem - based powers. Pearl might struggle with the concept of being mortal and having to learn skills like cooking and cleaning from scratch. Amethyst could find the human form both exciting and frustrating as she'd have to deal with things like getting tired easily. Garnet might have an interesting time adjusting as she's used to being a fusion.
In certain Steven Universe human military fanfictions, there's the concept of a joint military - Gem task force. This task force has to deal with threats that neither the military nor the Gems could handle alone. It involves a lot of character development as the members from different backgrounds learn to work together. There are also cultural clashes and the need for mutual understanding, which makes for a really engaging read.
One great Steven Universe human military fanfiction is 'The Garnet Initiative'. In this story, the human military teams up with Garnet to face a new alien threat. It has a really interesting take on how the military would interact with the Gems.
He would probably have a very mixed reaction. On one hand, seeing how fans view his world and his story could be really cool. He might enjoy seeing different versions of himself and his friends. However, if there are inaccuracies or things that go against his values in the fanfiction, he could also be a bit put off. It really depends on the nature of the fanfiction he's reading.
A great fanfiction could be about Steven and Connie swapping bodies. This would lead to a lot of humorous moments as they try to figure out how to act like the other. Connie would struggle with Steven's powers, and Steven would have to deal with Connie's more studious and disciplined life. It could also be a chance for them to understand each other on a deeper level.
A lot of these fanfictions also explore their individual growth. Peridot might grow out of her more rigid gem ways with Steven's influence, and Steven could learn new ways of problem - solving from Peridot. It's always fascinating to see how different authors imagine their relationship evolving in different scenarios.
