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.
For a more angsty read, there's 'Sirius' Forbidden Love'. It deals with the difficulties of Sirius being in a gay relationship in the wizarding world. It shows the internal struggles he faces, as well as the external pressures, and how love still manages to find a way through all that.
The theme of redemption also shows up. Since Sirius had a somewhat 'tainted' reputation in the eyes of the Black family, some fanfictions explore if Orion could have played a role in his redemption or if Sirius could have redeemed the family name in Orion's eyes.
There's a fanfic called 'Sirius and Hermione's Unbreakable Bond'. It starts with Sirius seeing Hermione's potential from the very beginning. He becomes a mentor to her, which is different from their normal Hogwarts interactions. The story delves deep into how their different experiences in the wizarding world bring them closer. Hermione's intelligence and Sirius' rebellious spirit create a unique dynamic between them.
Yes, it can be. Sirius Black has a complex character with his own backstory, and when incorporating him into Hermione - centric fanfiction, it's tough to balance his personality traits like his recklessness and loyalty with Hermione's studious and rule - following nature. Their different personalities and the existing canon storylines can make it a difficult task to create a believable and engaging plot.
Perhaps in the fanfiction, Sirius is mad at Harry because Harry has befriended someone Sirius doesn't trust. Sirius, being protective of Harry, might see this new friendship as a threat. He could be worried that this person will lead Harry astray or put him in danger, and his anger towards Harry stems from his concern for Harry's well - being.
The theme of freedom is quite important too. Sirius was locked up in Azkaban for a long time, and when he escaped, he was fighting for his freedom. Fanfictions often expand on this, showing his journey to fully regain his freedom and his place in the wizarding world, while also dealing with the prejudice against him because of his supposed crimes.
You can start by looking on fanfiction websites like Archive of Our Own. There are often tags for 'Sirius Black' and 'Sentinel Guide' that can help you find relevant stories. Some popular ones might have high ratings and a lot of reviews.
A possible fanfiction plot could involve Sirius Black being a Sentinel and his Guide being a mysterious new student at Hogwarts. Their connection is immediate and strong. As they work together, they start to uncover secrets about the wizarding world that no one else knows. They face challenges from dark wizards who want to use Sirius' powers for their own evil purposes. Their relationship as Sentinel and Guide becomes a key element in their fight against the darkness, and their love story could also be intertwined in the plot.
A good Sirius Black fanfiction should have a strong understanding of his character. It needs to capture his loyalty to his friends, his wild side as part of the Marauders, and his sense of justice. For example, if it shows him standing up for the underdog at Hogwarts, it's on the right track.
