Fanfiction about Harry, Ginny and Polyjuice Potion: What are some interesting plot ideas?

One idea could be a situation where a group of Hogwarts students accidentally use the Polyjuice Potion and swap identities in the middle of an important exam. It would lead to chaos as they struggle to answer questions in each other's forms.

Well, perhaps a character uses the potion to turn into a teacher to change grades in order to get a friend out of academic trouble. They end up having to teach a class while in the teacher's form and hilarity ensues as they struggle to keep up with the subject matter. It could also lead to some self - discovery for the character about the challenges of teaching.

One interesting plot twist could be when the polyjuice potion is accidentally modified. For example, instead of just changing a person's appearance, it also gives them some of the magical abilities of the person they are transforming into. This could lead to a character who is normally not very powerful suddenly having extraordinary skills, which would completely change the power dynamics in the story.

The Polyjuice Potion could create misunderstandings in their relationship. For example, if Ginny sees Harry seemingly flirting with someone who is actually him under the influence of the potion, she might get angry. On the other hand, if Harry sees Ginny acting strangely because she has been transformed by the potion, he could worry about her being under some sort of dark magic influence.

One idea could be a character using Polyjuice Potion to switch with a Death Eater to infiltrate their ranks and gather information for the Order of Phoenix. This would lead to a lot of tense moments as they try not to be discovered.

One interesting fanfiction could be where Hermione uses the Polyjuice Potion to infiltrate a group of dark wizards. She might have to disguise herself as one of them to gather crucial information for the Order of Phoenix. In this fanfic, she could face challenges like maintaining the disguise and not being detected by the dark wizards' magic detectors.

One idea could be a student using Polyjuice Potion to turn into a house - elf to spy on the Hogwarts kitchen secrets. They might discover a hidden passage that the house - elves use for their own purposes. Another could be turning into a hippogriff to experience flight in a new way and interact with other magical creatures from their perspective. Maybe a character uses it to turn into a Blast - Ended Skrewt to find out why they are so aggressive and what their purpose is in the wizarding world.

Harry Potter himself is quite common. Writers like to put him in situations where he has to use the potion to transform for various reasons, like infiltrating the Death Eaters.

One plot idea could be that Draco accidentally drinks a love potion meant for someone else and he starts acting strangely towards Harry. Harry is initially confused but then realizes what's going on and has to find a way to reverse the potion's effects while also dealing with his own mixed feelings for Draco.

Hermione Granger is quite common. Since she's very intelligent and resourceful in the original series, in fanfiction she often uses the Polyjuice Potion for various purposes, like solving mysteries or getting access to restricted areas.
