One popular trope is the fusion of Pokemon with the Gems from Steven Universe. For example, a Pikachu - like Gem or a Gem - powered Pokemon. It combines the unique powers and characteristics of both universes in an interesting way.
A third popular trope is the power - up or transformation trope. A character gains new powers by combining elements from both Pokemon and Steven Universe. This could be a trainer getting Gem - like powers or a Gem character being able to use Pokemon moves, and it often drives the plot forward in exciting ways.
The 'fish out of water' trope is also common. A character from one universe (either Pokemon or Steven Universe) finds themselves in the other universe and has to adapt. This leads to a lot of comical and heartwarming moments as they learn about the new world.
A third trope is the 'hidden power' trope. The male reader starts off as an ordinary person but gradually discovers that he has a hidden gem - related power. This power is usually crucial in solving the various problems and challenges that he faces throughout the story, making for an exciting journey of self - discovery.
The 'redemption arc' can also be a common trope in Steven Universe Pearl x OC fanfiction. Maybe the OC has a troubled past or made some mistakes, and Pearl helps them to find a new path. This trope allows for a lot of character development and emotional depth. Also, the 'slow - burn' romance trope is popular. Given Pearl's reserved nature, a slow - building relationship between her and the OC can be very engaging, with lots of small, meaningful interactions building up over time.
Peridot is quite popular too. Her unique personality, especially her growth from a somewhat antagonist to a more friendly character, makes for great storytelling in crossovers. In a crossover with 'Ben 10', Peridot's technological knowledge could be paired with Ben's Omnitrix - related adventures.
One popular crossover is having the Crystal Gems from Steven Universe team up with the Avengers to fight a common enemy. For example, they could battle a powerful alien threat that neither group could handle alone. The unique powers of the Crystal Gems, like Garnet's future vision and Steven's healing powers, combined with the Avengers' superhuman abilities would make for an exciting story.
One popular theme could be exploring different relationships. For example, how a female Steven would interact with the existing characters like Pearl, Amethyst, and Garnet. Maybe she'd have a different dynamic with them, bringing out new sides of their personalities. Another theme might be self - discovery. Since Steven in the original series has a journey of understanding himself and his powers, a female Steven could have a similar yet distinct journey, perhaps facing different challenges due to being female in the Crystal Gem world. Also, themes of friendship and loyalty are likely to be explored, as they are central to the 'Steven Universe' series.
One popular theme is redemption. Spinel has a troubled past, and many fanfictions focus on her journey towards redemption with Steven's help. For example, stories where Spinel tries to make up for her past actions.
Yellow Diamond is also quite popular. She represents the power and authority of Homeworld. Fanfictions might focus on her character development, for example, showing a softer side of her or exploring how she came to be so strict in her rule. Her interactions with other Diamonds and her role in the overall hierarchy of Homeworld are interesting aspects to write about.
One popular trope is the 'reunion' trope. Maybe they've been separated for a while, due to different Pokemon - training paths, and then they meet again and there are all kinds of emotions. Another is the 'rival - turned - ally' trope. They start as rivals but then realize they are stronger together.
In Pokemon X Male Reader fanfiction, the 'Lost in a New World' trope is often seen. The male reader is somehow transported to the Pokemon world and has to adapt. The 'Power of Friendship' trope is also prevalent, emphasizing how the male reader's relationships with his Pokemon and other trainers are crucial. Another trope is 'Redemption Arc', where a previously antagonist character or Pokemon is redeemed through the male reader's influence.
One popular trope is the 'fish - out - of - water' situation. Naruto characters finding themselves in the Pokemon Mystery Dungeon world and being confused by the new environment. Another is the power - up trope, where a character from either universe gains new abilities by interacting with the other.
