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.
A more detailed fanfiction idea could involve Hermione creating a new version of the Polyjuice Potion with lemon as a key ingredient. She might be trying to improve the potion's effectiveness or perhaps make it more palatable. However, this new version has unforeseen side effects. For instance, it not only changes her physical appearance but also gives her the personality traits of someone who loves lemons passionately. So she starts acting in a very zany way, much to the confusion of her friends, and she has to figure out how to reverse the effects while still in the middle of an important adventure.
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.
In Harry Potter fanfics, polyjuice potion is often a really cool plot device. It allows characters to transform into others, which can lead to all sorts of interesting situations. For example, a character might use it to infiltrate an enemy group or to play a prank on their friends. It adds an element of mystery and fun to the story.
She could use the Polyjuice Potion to turn into someone who has a special connection to lemons. Maybe a lemon - farmer in the wizarding world. And through this transformation, she discovers new things about the magical properties of lemons that she never knew before.
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.
There is a fanfiction where Hermione creates a new version of the Polyjuice Potion. This new potion has some unexpected side - effects when she tests it on herself. It gives her not only the physical appearance but also some of the magical abilities of the person she was trying to imitate. This leads to a whole new adventure as she tries to control these new powers.
Sure. A lot of fanfic writers are more interested in the magical and plot - driving aspects of the Polyjuice Potion. They might write about how characters use it to infiltrate a group of dark wizards or to get out of a tricky situation. There are also fanfics that play with the idea of accidental uses of the potion and the comical or dangerous situations that can arise from that.
In a Harry Potter polyjuice potion mishap fanfiction, the person who drinks the potion wrongly might start to exhibit the wrong personality traits. Let's say they were trying to transform into Hermione but due to the mishap, they start acting like Draco Malfoy instead. This would cause chaos as they would be doing things completely out of character for the person they were supposed to be imitating. They might start bullying other students or being mean to their friends, creating a lot of drama and confusion in the wizarding world.
Luna Lovegood can also be a very creative character in relation to the polyjuice potion. Given her unique perspective on magic, she might discover that the potion has properties that others have overlooked. Maybe she finds that it can be used to communicate with plants or other inanimate objects while in the form of someone who has a special connection to them.
