Potential characters could include a young intern, let's call him Tom. He's eager to learn but often makes mistakes. There could be an elderly janitor named Ben who has worked at Blaine Hospital for decades and knows all its hidden corners. And a group of children patients, led by a little girl named Lily, who bring some joy to the otherwise serious hospital environment.
Well, there could be doctors like Dr. Smith, a brilliant surgeon. Nurses such as Nurse Johnson, who is very kind but strict about following procedures. There might also be patients like Mr. Brown, a friendly old man with a heart condition. And don't forget the hospital administrators like Ms. Davis who is always trying to keep the hospital running smoothly.
Obviously, Madam Pomfrey is a key character as she runs the hospital wing. Harry, Ron, and Hermione could also be characters, perhaps they visit a friend who is ill. There could also be some minor characters like Neville who might get injured during a Herbology class and end up in the hospital wing.
Maybe it could center around a group of volunteers at Blaine Hospital. They come from different backgrounds but bond over their love for helping patients. One volunteer discovers a mystery about an old wing of the hospital that has been abandoned for years, and they all work together to uncover its secrets while still fulfilling their volunteer duties.
Well, in addition to Sakura, there might be a strict but fair psychiatrist. He could be a key character as he tries to diagnose and treat Sakura. There could also be a group of patients that Sakura befriends. For instance, a young girl who is in the hospital due to severe anxiety and an older man who has hallucinations. These characters could interact with Sakura in different ways, some being helpful, others being a hindrance to her progress in the mental hospital.
Obviously, his old friends like James Potter or Remus Lupin could come to visit him in the hospital. They would bring some of their old Hogwarts memories and cheer him up. Then there could be the hospital staff, like a strict but kind - hearted matron who takes care of Sirius. Also, other patients in the hospital might interact with him, such as an old wizard who has some valuable advice for Sirius.
It could be a random act of violence by a criminal who was in the wrong place at the wrong time. There are some bad elements in the area where Blaine was and they just targeted him without any specific reason other than opportunity.
A wind - up mouse could be a potential character. It's always scurrying around and stumbles upon the toy lemon by accident. Then there could be a wise old toy owl that gives advice to the other toys about the significance of the toy lemon. And a bouncy rubber ball that adds some fun and energy to the group of toys in the fanfic.
Obviously, Naruto could be one of the main characters. He could be either a patient or someone helping out at the hospital. Another main character could be Sakura. Since she has medical skills, she could be a doctor or a medic - ninja in charge at the hospital. And then there could be a new character, like a young orphan who is being trained as a medic - ninja at the hospital and has an interesting backstory.
Well, Chanwoo could be a patient with a rare disease. In that case, the main characters could be the medical team trying to cure him. There would be the lead doctor in charge of his case, a young and ambitious researcher who is determined to find a cure, and Chanwoo's family members who are constantly by his side, providing emotional support and sometimes causing a bit of drama in the hospital setting.
It could be a young orphan. Orphans often struggle to find a place where they belong, so this character would have a strong motivation to search for that special place. They could be kind - hearted but also have a bit of a feisty side to survive in the world of the fanfic.
Jackie Estacado from 'the darkness' is an obvious choice. His connection to the Darkness power makes him a central figure and his skills and personality can drive the story forward in a crossover.
