The ratcatcher short story might be about a person who catches rats. There could be a description of the ratcatcher's methods, like using traps or poison. Maybe it shows his daily life and the challenges he faces while dealing with the rat problem in a particular area, such as in a town or on a farm.
Well, in most of the established 'Harry Potter' lore, Ginny is in love with Harry, so a 'ginny tries to kill harry fanfiction' is a very out - of - the - box concept. It could be a dark exploration of an alternate universe where Ginny has been corrupted or influenced by some dark magic or external force that makes her turn against Harry. Maybe the writer wants to explore the extreme consequences of a character going completely off - their - normal - path.
In 'amy tries to kill sonic fanfic', it might be that Amy has been tricked by an enemy. The enemy could have made her believe Sonic has done something really bad. So, out of a sense of justice or revenge, she tries to take Sonic's life. However, it's all a big ruse, and Sonic has to figure out how to make Amy see the truth before it's too late.
I don't know who created this particular fanfic. There are so many Sonic fans out there creating various fanfics, and it's hard to pinpoint the creator without more information.
Peter could be a disgruntled noble in the fanfiction. He might be someone who has been overlooked for promotions or honors by the emperor, and this has led to his resentment and desire to kill the emperor.
The main character is surely the ratcatcher. But there could be other characters too. For instance, there might be a young boy who is fascinated by the ratcatcher's work and follows him around. Or there could be an old woman who warns the ratcatcher about the 'cursed' rats in the area. These additional characters would add more depth and interest to the story.
Maybe in this fanfiction she experiences a great loss, like the death of a loved one in a very tragic way. For example, if Ron or Harry were killed in a battle and she blamed herself for not being able to prevent it. This overwhelming guilt could be a reason for her to try to kill herself.
Overall, Peacemaker is reasonably faithful to the comics. Some details might be tweaked for the screen adaptation, but the core elements remain intact. The characters and their arcs are largely consistent.
