The 'hidden strength' trope is also seen. Despite being in a 'bottom' role, the black male character may have an inner strength that is revealed over time. It could be a mental or emotional strength that helps him face challenges. There may also be the 'redemption' trope if the character has made mistakes in the past and is working towards making amends or being a better person within the story.
One common theme is self - discovery. Since Jacob is often in a different role in these fanfics, he goes through a process of understanding himself better. Another theme is relationship exploration, especially his relationships with other characters like Bella or the other werewolves in new and different ways.
One common theme is friendship. Since Sirius has strong friendships in the original story, in these fanfics, his friends often play important roles in his life and character development. For example, how they support him during tough times.
Fanfic can be a very niche area. Maybe you could start by looking at the fandoms you're interested in that might feature black male characters. For example, if you like a particular TV show or movie, check out the related fanfic communities. They might have some great stories with 'bottom black guy' themes. Just be sure to respect the rules and guidelines of those communities.
In these fanfics, the 'shared interest' trope is often seen. For example, they both love a certain type of music or literature that no one else around them cares about. This shared passion becomes a strong bond. Then there's the 'unexpected encounter' trope. They might meet in a really strange or unexpected place that makes their connection seem fated. And the 'protective instinct' trope can also be present. The popular guy feels the need to protect the unpopular girl from the mean remarks or actions of others.
One popular trope is the 'hurt/comfort' trope. It often involves Sam getting into some sort of difficult situation, either physically or emotionally, and then being comforted by his partner. For example, he might get injured during a mission and his love interest takes care of him.
One common trope is the power dynamic. In abo fanfic, alphas are often depicted as having more power, both socially and physically. Another is the mating bond. It's a central concept where the connection between characters, especially an alpha and an omega, is intense and often drives the plot. For example, in some fanfics, the mating bond might be a source of conflict if it goes against the characters' prior relationships or their own self - identity.
One common trope is the makeover. The popular guy might help the unpopular girl change her appearance, which then leads to a newfound confidence in her. Another is the 'opposites attract' situation where their different social statuses in school create interesting dynamics. For example, they might get paired up for a school project and slowly start to fall for each other despite their initial differences.
A trope that is often used is the 'mystery - solving' one. Brian and Stewie team up to solve a mystery in Quahog, like a string of strange disappearances or a mystery about a local legend. They use their combined skills, Brian's street - smarts and Stewie's deductive reasoning, to crack the case. It makes for an exciting and engaging fanfic plot.
I'm not entirely sure specifically what 'bottom pitch black fanfic' is about without more context. It could potentially be a very dark or edgy piece of fan - created fiction, perhaps with a lot of gloomy or negative themes related to the 'bottom' concept in certain fandoms.
Some typical tropes in Naruto fanfic include 'Underdog to Hero'. Many fanfics focus on a character who starts off as weak or underestimated but rises to great power. The 'Mentor - Protégé' relationship is another one. A new or existing character might become a mentor to someone, like Kakashi to Naruto. And 'The Chosen One' trope is still used, where a character is prophesied to save the world or bring great change, much like Naruto was in the original series.
