Steven, the half - human, half - Gem protagonist, and Yellow Diamond, a high - ranking Gem. In this fanfiction, they are at the center of the action. Steven's character is full of compassion and a desire for harmony, while Yellow Diamond is a complex character with her own set of values and power - driven mindset.
Perhaps Steven and Yellow Diamond end up having a long - awaited conversation. They could discuss the past, the reasons for the war between the Gems, and Steven could share his unique experiences as a half - human, half - Gem. This might cause Yellow Diamond to question her long - held beliefs and start to consider a different path for the Gem Homeworld.
The main characters would be the son of Yellow Diamond, of course. Then, the Crystal Gems like Garnet, Amethyst, and Pearl would be important. They could be the ones who initially view the son with suspicion but later come to accept him. Another possible main character could be Peridot. She has knowledge of the Diamond hierarchy and could help the son understand his place in it, while also learning from him about a different perspective on the Diamonds.
Obviously, Steven and Pink Diamond are the main characters. Steven, with his unique ability to understand and empathize with all beings, and Pink Diamond, with her complex and mysterious past. Their interaction would be the core of the fanfiction.
It could be another gem who doesn't want Steven and White Diamond to form an alliance. Maybe a rogue gem who fears that their combined power would disrupt the current power balance in the gem universe.
In addition to Steven and Pink Diamond, other characters from the Steven Universe series can also play important roles. For example, the Crystal Gems like Garnet, Amethyst, and Pearl might be involved. They could be skeptical or supportive of Steven's relationship with Pink Diamond, adding extra layers of drama to the fanfiction.
Peridot is a character that could be paired with Yellow Diamond in fanfiction. Since Peridot was once under Yellow Diamond's rule, there can be stories about her loyalty, her possible defection, or how Yellow Diamond views her. There could also be fanfictions that pair Yellow Diamond with other minor Gems from her colonies, exploring the power dynamics and relationships on a more micro level within the Gem society she oversees.
Steven is often paired with Black Diamond in fanfiction. Their interactions can be really interesting as Steven has his unique way of approaching Gems and his powers. He might try to understand Black Diamond or even persuade her to change her ways if she's portrayed as a more antagonistic figure.
Pearl, who was once Pink Diamond's servant, is another main character in many of these fanfics. Her loyalty to Pink Diamond, and how that loyalty has changed over time and affected her own character development, is a major aspect in these stories.
Well, it's likely that Steven would still be one of the main characters. He often plays a central role in any Steven Universe - related story. Alongside him, there could be new characters created specifically for this fanfic that are somehow connected to the Black Diamond. And of course, any of the existing main Gems from the show like Garnet, Amethyst, and Pearl might also be important characters in this fanfic, especially if they interact with the Black Diamond in some way.
Well, one possible plot could be that the son of Yellow Diamond is initially conflicted about his identity. He might be raised among the Crystal Gems, but his Diamond heritage makes him question where he truly belongs. He could struggle with the power within him, which is different from the normal Gem powers. Maybe he has the ability to control some kind of unique energy related to Yellow Diamond's powers. And throughout the fanfiction, he goes on a journey of self - discovery, learning to balance his two very different heritages.
