Sirius can help Harry in fanfics by using his connections. He was part of the Order of the Phoenix. So, he could introduce Harry to other members, who can offer different kinds of help. For instance, they might provide safe houses, give Harry access to rare magical items, or teach him advanced magic that he can't learn at Hogwarts.
Sirius often provides emotional support to Harry in fanfics. Since Harry has lost his parents, Sirius, being his godfather, fills that parental role to some extent. He might share stories about Harry's father, which gives Harry a sense of connection and pride. Also, Sirius's skills as a wizard, like his combat abilities, can be used to train Harry or defend him when he's in danger.
In some Harry Potter fanfics, goblins might help by providing magical items. For example, they could offer a powerful wand or a special charm that the main character needs. Goblins are known for their craftsmanship in the wizarding world, so they could also help in repairing or enhancing magical objects.
In Harry Potter fanfic, Marge could help by providing a contrast to the wizarding world. For example, her Muggle - centric views and often - bigoted opinions can highlight the differences between the magical and non - magical communities. This can add depth to the story as characters interact with her and either oppose or are influenced by her ideas.
In some fanfics, Snape might help by using his knowledge of the situation. He could provide crucial information that clears Harry's name. Maybe he has some insights into Sirius' situation or the events that led to Remus blaming Harry that others don't have, and he decides to share that information to set things right.
Sirius could help Harry cope by sharing his own experiences of being an outcast in his family. He could tell Harry that just because his parents did this horrible thing, it doesn't mean he's unlovable. Sirius could also introduce Harry to his friends in the wizarding world, like Remus, who could also offer support and friendship.
The Lipstick Sirius Veil might be used to drive the conflict in the fanfic. Maybe different characters have different ideas about what the lipstick and the veil combination means. Some might want to use it for good, while others for evil. This creates a power struggle. For instance, if the veil is protecting a powerful magical object, and the lipstick is the key to accessing it, characters will fight over who gets to use the lipstick on the veil. Sirius could be caught in the middle of this struggle, having to choose a side.
Harry's character would be shaped by Sirius' values. Sirius values loyalty above all else, and Harry would grow up with a deeper understanding of what it means to be loyal to friends and family. He would also be more in touch with his emotions. Sirius, having suffered so much, would encourage Harry to express his feelings. This would make Harry a more well - rounded and emotionally intelligent character compared to the sometimes stoic Harry in the original series.
It changes the family dynamics. In the original story, Harry is an orphan with the Dursleys as his guardians. But in this fanfic, with Sirius as his blood - adopted father, he has a more magical and positive family environment from the start.
Often, the fanfic will show Harry crying while remembering all the good times with Sirius. It might be a flashback of them joking around or Sirius giving Harry some important advice. These memories make his crying even more heart - wrenching as he realizes he'll never have those moments again.
Well, in canon, Sirius doesn't really get the chance to fully raise Harry. But in fanfics, he can be a positive male role model. For example, he might teach Harry some dark arts defenses that he didn't learn at Hogwarts. Also, he could introduce Harry to different parts of the wizarding world that Dumbledore kept him away from in the original story.
As time goes on, Harry could start to explore what it means to 'please' Sirius. He might recall their past relationship, the things Sirius likes and dislikes, and try to use that knowledge to his advantage. He may also feel a sense of loyalty towards Sirius that, despite the odd circumstances, makes him more accepting of the situation. For example, he might remember Sirius' love for adventure and try to engage in some magical adventures with him in a way that 'pleases' him.
