Some common themes are Snape's complex relationship with Harry Potter. It could explore how Snape was secretly protecting Harry all along.

Well, Sirius Black's scars in fanfiction can vary a lot. Some fanfictions might focus on the emotional scars that are not as visible but are just as deep. His scars could be used to show his connection to other characters too. Maybe a scar he has is linked to a shared experience with Remus Lupin, which then builds on their friendship in the story.
In some fanfictions, Sirius Black helps Hermione with her studies. For example, he might share his own experiences with difficult spells and potions, which he learned during his time at Hogwarts. This kind of help can give Hermione new insights and make her even more proficient in magic.
One possible fanfiction idea could be that Sirius decides to cut his hair as a symbol of starting anew after escaping Azkaban. His long, shaggy hair was a part of his wild look, but now he wants to look more presentable to his friends and family. He might cut it in a simple yet stylish way, and his friends' reactions could range from shock to admiration.
There probably is. The Harry Potter fandom is huge and full of diverse ideas. Writers might explore this idea to add new twists to the story, like how Harry's relationship with Sirius would be re - imagined if he were his daughter, and how it would change the overall plot dynamics.
In a Sirius Black tattoos and rituals fanfiction, the tattoos might be a form of protection. The ritual could be a family tradition passed down through the Blacks. For example, he might have a tattoo of a wolf on his arm, and the ritual to complete it requires him to recite an incantation in an ancient tongue while standing in a circle of runestones.
One idea could be that Sirius Black's daughter, who has been hidden away all this time, discovers her true identity while trying to break into Azkaban to clear her father's name. She could have some unique magical abilities that help her in this dangerous quest.
In some fanfiction, yes. Fanfiction writers often like to play with the relationships in the Harry Potter universe. They might create a scenario where Sirius Black is Harry Potter's father, perhaps exploring how this would change the story's dynamics, the relationships between characters, and the overall plot.
