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.
Well, it could be about Steven having some sort of magical or scientific accident that turns him into a girl. Then he has to deal with the new body, different social expectations, and how his friends and family react to this big change.
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.
Perhaps she's a time - traveler from a future where the events in Steven's world have led to some big changes. She could be on a mission to prevent a certain catastrophe from happening, and her presence in Steven's time is a crucial part of that plan. She might have knowledge of future events and technologies that seem strange to Steven and the others.
A love interest who breaks the girl's heart can also be a main character. His actions, like cheating on her or suddenly leaving her without an explanation, can be the catalyst for her transformation into an evil character. Then the story could revolve around her trying to get back at him in devious ways.
Ichigo and Steven would be obvious choices. Ichigo is the main protagonist in Bleach, strong - willed and with great power. Steven, on the other hand, is kind - hearted and has a unique way of looking at the world. Their different personalities could lead to some interesting interactions. They could start off as strangers in a new combined universe and gradually become friends as they face common enemies or challenges.
If it was a crossover with "She - Ra and the Princesses of Power", Adora could be a main character. Her strong leadership and the power of She - Ra would be an interesting contrast to Steven's more laid - back leadership style. Together, they could fight against a common enemy that threatens both their worlds.
Well, clearly Steven and Connie are the main characters. They are the focus of the fanfiction.
The main characters are obviously Steven and May.
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.
Lapis Lazuli could be a great addition. She has a complex relationship with Peridot, and her presence could add some drama and depth. For example, she might be initially suspicious of Steven and Peridot's friendship, thinking that Steven is influencing Peridot too much. But over time, she could come to see the positive aspects of their bond.
