One interesting fanfiction could be where Hermione uses the Polyjuice Potion to infiltrate a group of dark wizards.

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.

A possible plot is that Ginny accidentally drinks Polyjuice Potion that was meant for someone else. She transforms into an unknown person and gets lost in the wizarding world. Harry then has to find a way to reverse the effect and find her. He might have to go on a journey through different wizarding communities and face various challenges. Along the way, he discovers some secrets about the Polyjuice Potion that he didn't know before, like a rare ingredient that can make the potion's effect last much longer than normal.
One interesting plot twist could be when the polyjuice potion is accidentally modified.

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.

One interesting fanfiction could be where a character accidentally uses a love potion in a lemon - scented drink. Maybe Hermione accidentally drinks it and has some comical interactions with Ron.
