Riley is also a good candidate. He's impulsive and always looking for excitement. He might make what he thinks is a harmless mistake, like getting involved with the wrong crowd for a quick thrill, but it could turn into a much bigger deal. His actions could then drive the plot of the fanfiction as he tries to get out of the mess he created.
Huey could be the main character. Given his intelligent and often idealistic nature, he is likely to be involved in situations where a small misstep could lead to a complex chain of events. His strong beliefs might cause him to make a mistake while trying to uphold justice or educate others.
It could be about a character in 'The Boondocks' making a small error that has unexpected and far - reaching consequences. Maybe Huey makes a mistake in one of his social justice pursuits that ends up teaching him a new perspective.
It could be two high - school students. One is a popular jock and the other is a quiet bookworm. A beautiful mistake could be that the jock accidentally bumps into the bookworm in the library and knocks over all their books. This leads to an unexpected friendship and maybe something more as they get to know each other better.
Perhaps it could be a new character created specifically for the fanfiction. A mysterious outsider who Jazmine met by chance and had a brief encounter with that led to her pregnancy.
Most likely, Serpentina could be one of the main characters. Since the fanfiction is named after her, she is probably central to the story. It could be that she is a unique or powerful being, and the story unfolds around her actions and the interactions she has with others.
It could be an original character created just for the fanfiction. A girl with a spunky personality, who is full of energy and has a big heart. Maybe she has a unique style, like she loves to wear mismatched socks and big floppy hats.
Aria could be a great main character for a redemption fanfiction. She had her own secrets and moments of dishonesty in the original series. So, in the fanfiction, she could be on a journey to be completely honest with everyone, especially her friends and family, and make up for the times she wasn't.
Since it's a fanfiction about a 'perfect stranger', it's likely that the main character is this stranger. But without reading it, it's hard to say more about who they are exactly.
Riley Freeman is another important character. He is Huey's younger brother. Riley is more influenced by the mainstream and often gets into comical yet thought - provoking situations.
One interesting pairing could be Naruto and Huey Freeman. Naruto's naivete and idealism could be contrasted with Huey's more politically aware and cynical nature. They could learn a great deal from each other. Naruto might teach Huey about the power of believing in oneself and never giving up, while Huey could introduce Naruto to the complex world of social and racial politics.
