The main characters are obviously Steven and May.
Besides Steven, the main characters could include the villains he's faced in the past. Now that he's a girl, they might underestimate him or treat him differently. His father Greg could also play a big role. Greg might be a bit shocked at first but then would be super supportive, trying to understand what his 'new' child is going through. And there could be new characters introduced, like other girls in the town who become friends with Steven and help him adapt to the female world.
Steven would be the main character as he's the one getting poofed. But depending on the context, the Crystal Gems - Garnet, Amethyst, and Pearl - would likely be important characters too. They would probably be involved in the aftermath of Steven getting poofed, either trying to revive him or dealing with the situation his poofing has caused.
Well, clearly Steven and Connie are the main characters. They are the focus of the fanfiction.
Obviously, Pearl is one of the main characters. She's the refined, sword - wielding Gem we know from the show. In the context of Pearl Lemon fanfiction, Lemon becomes a central figure as well. This new character could be anything from a mysterious new Gem to a human with some special connection to the world of Gems. Their interactions and the relationship between them form the core of the fanfiction stories.
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.
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.
The main character is Steven. Alongside him, his father Greg could be a crucial character. Greg has always been there for Steven in different ways, and he might be the one who can reach Steven on an emotional level during his corrupted state. Lion, Steven's magical pet, could also be a main character. Lion has the ability to travel through dimensions and might be able to find a solution to the corruption in some far - off place.
Pearl, Garnet and Amethyst would surely be main characters. They were probably waiting anxiously for Steven's return. Once he is back, they could help him readjust to life at home. They might also assist him in dealing with any post - traumatic stress or new challenges that emerged from the Grem war.
Obviously, Peridot is one of the main characters as she's the one who gets cracked. Steven is also likely to be a main character since he often helps the other gems in difficult situations. The other Crystal Gems like Garnet, Amethyst, and Pearl might also play important roles as they would be involved in Peridot's situation, either trying to help her or dealing with the consequences of her being cracked.
In 'Steven Universe Watch the Future fanfiction', Steven is bound to be a central figure. He's the protagonist of the original series, after all. Alongside him, the Crystal Gems - Garnet, Amethyst, and Pearl - are very likely to be main characters. They've been with Steven through thick and thin. Additionally, characters like Peridot, Lapis Lazuli, and Bismuth, who have become important parts of Steven's life in the later parts of the series, could also be main characters. Connie, with her connection to Steven and her own growth in the story, is also a strong candidate for a main character.
