One common theme is recovery. After being hurt, Sirius often has to go through a process of physical or emotional healing. For example, in many fanfictions, he has to deal with the after - effects of a spell gone wrong.
Well, in these fanfictions, we see a more vulnerable side of Sirius. For example, in many of them, his time in Azkaban is explored in greater detail. We get to understand the true extent of the psychological damage it caused him, which makes his character more three - dimensional.
One popular 'sirius hurt fanfiction' is 'The Healing Process'. It focuses on Sirius's emotional turmoil after a particular event in the wizarding world and how his friends help him through it.
I really liked 'Broken Wings'. In this fanfiction, Sirius is physically hurt during a battle and it explores how he copes with the injury while also dealing with the politics within the wizarding world. It has a great balance between action and character development.
I don't think Will Halstead will hurt fanfiction. Fanfiction is a creative outlet for fans, and it often takes different directions from the original storyline. Even if something in the official show changes for Will Halstead's character, fanfiction writers can always adapt or just continue with their own versions. There's no real threat from the character himself to the existence or quality of fanfiction.
Harry Potter would likely be one of the main characters affected. Sirius was his godfather, so any changes Sirius makes could have a huge impact on Harry's life, his understanding of his family, and his role in the wizarding world.
Another possibility is a jealous student at Hogwarts. There are always students who might be envious of Hermione's academic achievements. They could set up a prank or a trap that goes wrong and ends up hurting her. For example, a student who is tired of Hermione always getting the top grades in Potions might tamper with her cauldron during a class experiment, resulting in an explosion that hurts her.
Emotional hurt is also popular. This could involve things like heartbreak, betrayal by someone he trusts, or the weight of his long - lived experiences and the losses he has endured over the centuries. It makes for some really deep and angsty stories.
Well, often in Hurt Kakashi fanfiction, there's the theme of his physical injuries and how he copes with them. Given his dangerous line of work as a ninja, he gets hurt a lot. Writers might explore how he deals with long - term or serious injuries that could potentially end his ninja career. Also, his relationships can be a source of pain. For instance, his complex relationship with Obito and how that affects his mental state when they are at odds.
