There could be a fanfiction where Hermione comes up with a brilliant prank. She uses a spell to make Umbridge's parchment write out all the unjust rules she has made instead of whatever Umbridge is trying to write. Every time Umbridge tries to write a memo or a note, the parchment just keeps repeating things like 'No groups larger than three' and 'No fun allowed' over and over again, driving her mad.
The Weasley twins, Fred and George, are often the main instigators. They have a reputation for their mischievous pranks in the original series, so it's natural that they would be at the forefront of pranking Umbridge in fanfiction. Their creativity and disregard for authority make them perfect for coming up with elaborate and hilarious pranks against her.
One creative prank could be that Harry uses magic to make Umbridge's quills write only nonsense whenever she tries to write a decree. Another could be that he enchants her office so that every time she sits in her chair, it makes a loud and embarrassing noise, like a donkey braying. And he could also charm her teacup to refill with a really bitter-tasting potion instead of tea.
Fred and George Weasley are also favorites. Their mischievous nature can be amplified in fanfictions. They could create new and even more spectacular magical pranks specifically aimed at Umbridge, like turning her office into a never - ending maze of trick stairs and hidden rooms filled with various magical creatures that drive her crazy.
Another idea is a time - travel fanfiction. Harry goes back in time and has to deal with Umbridge when she was a student. He tries to change her path so that she doesn't become the horrible person she is in his time. This could involve him befriending her and showing her the value of kindness and freedom.
In the 'Harry Potter Pranks Everyone' fanfiction, there could be some hilarious pranks. For example, a student might use a charm to make the Great Hall's ceiling show embarrassing memories of the teachers. Another prank could be to magically swap everyone's voices, so that when they talk, it comes out as someone else's voice. There could also be a prank where the Hogwarts Express gets diverted to a completely different location, and the students end up in a strange magical place full of odd creatures and unexpected challenges.
There's also a fanfic called 'Umbridge Unmasked'. This one shows a different side of Umbridge. Instead of just being a one - dimensional villain, it explores her insecurities and how they drive her actions. It's an interesting take on her character that makes you think more about her role in the wizarding world.
In Harry Potter fanfiction, rebellion against Umbridge is a popular theme. Many writers explore how the students, like Harry and his friends, might resist her tyrannical rule. They often show creative ways the characters use magic or their wits to undermine Umbridge's authority. For example, they might form secret study groups that are actually resistance cells.
A really funny prank could be where a student's quill is jinxed to write only in limericks. So when they're trying to take notes in class, instead of normal writing, it comes out as comical rhymes. This can be a source of great embarrassment, especially if they don't notice right away. Also, pranks with vanishing ink on important parchments are quite common in fanfiction. The victim thinks they've written important information, but it all disappears, leaving them frustrated and others amused.
Typically, Harry is one of the main ones. He has a knack for getting into and out of trouble with his pranks. Hermione might also be involved in some pranks in a more strategic way, using her vast knowledge of magic to create unique and elaborate pranks. And of course, the Weasley twins are almost always at the center of the most elaborate and chaotic pranks in the fanfiction.
