Yes, there might be such fanfictions out there. Fanfiction writers often explore alternative storylines, and the idea of Pettigrew turning on Voldemort and killing him is an interesting and unexpected twist. It could involve Pettigrew having a change of heart due to some complex reasons, like realizing the true evil of Voldemort's ways or having a personal vendetta against him that overrides his loyalty.
Often, Harry catches Pettigrew by using his invisibility cloak. He sneaks up on Pettigrew and then uses a stunning spell. It's a simple yet effective method that is often used in fanfictions as it plays on Harry's resourcefulness.
One possible consequence could be that he is immediately sent to Azkaban. Since he's a known traitor, the wizarding world would want to punish him severely for his crimes, which include betraying the Potters and framing Sirius Black.
There are fanfictions that explore Peter Pettigrew's early days at Hogwarts. Maybe he was once a more innocent boy who got influenced by the wrong crowd. For example, a story could show how he first met James, Sirius and Remus and how his insecurities led him down the path of eventually becoming a Death Eater.
One unique plotline is when Peter Pettigrew is given the chance to go back in time and change his actions. Another is where he has a secret alliance with a group of wizards who are trying to overthrow Voldemort for different reasons than the Order of the Phoenix. Also, some fanfics have him being a double agent all along, not really loyal to Voldemort but having his own agenda.
One common theme is redemption. Many fanfictions explore the idea of Peter Pettigrew seeking redemption for his actions. Since he was a traitor to the Potters, some stories show him trying to make up for it, often in relation to Harry.
Well, it's hard to say exactly. The story could have Pettigrew trying to control Nagini for his own purposes or perhaps getting caught up in her evil plans without realizing it.
Definitely Hermione and Ron. Hermione would use her intelligence to analyze the situation and come up with a plan. Ron would be the more impulsive one, ready to jump into action. Sirius Black could also be involved. Since he has a history with Pettigrew, he might have some insights into Pettigrew's actions and be able to help in the search for Harry. Also, the Weasley family in general might get involved as they are close to Harry.
Sure. 'Peter Pettigrew: The Untold Story' is an interesting fanfic. It shows Pettigrew in a different light, not just as a simple villain. It details his relationship with the other characters in a more complex way. Then there's 'The Mystery of Peter Pettigrew' which focuses on uncovering secrets about him that were not known in the original books. And 'Peter Pettigrew and the Path to Forgiveness' is about his journey towards redemption, which is quite a unique take on his character.
Well, perhaps Pettigrew gets tired of living in fear under Voldemort. He might find a powerful magical artifact that has the potential to kill Voldemort. As he tries to steal it for himself, Voldemort discovers his plan. In the ensuing struggle, Pettigrew manages to turn the artifact against Voldemort and kills him. This would then lead to Pettigrew having to deal with the consequences, like facing the wrath of the Death Eaters who are still loyal to Voldemort.
