The humor in Harry Potter fanfiction can come from the fact that it allows for more creative liberties. Fans can explore different relationships between characters in a light - hearted manner. For example, they might write about Hermione trying to teach Snape how to dance, which would be both absurd and funny considering their personalities in the original story. Also, the use of magic in comical scenarios, like using a spell to make Dumbledore's beard change colors every time he sneezes, adds to the hilarity.
In Harry Potter fanfiction, the crossovers can be a great source of humor. When characters from Harry Potter meet characters from other universes, like having Harry Potter and Sherlock Holmes team up. The contrast between their worlds and personalities can lead to many humorous interactions. Also, the misunderstandings that can occur in these crossovers are hilarious. Maybe Sherlock is trying to figure out how magic works and completely misinterprets it, while Harry is just baffled by Sherlock's deductive reasoning.
The use of character quirks can make a Harry Potter fanfic funny. For example, if the author exaggerates Neville's clumsiness in a new and creative way. Maybe Neville accidentally knocks over the entire potions classroom while trying to catch his toad. Another factor is the unexpected twists on the original story. Like if Dumbledore suddenly starts break - dancing during a serious Hogwarts meeting.
There was the time when Harry put on the Invisibility Cloak and tried to sneak into the restricted section of the library. But he accidentally bumped into a bookshelf and made a huge noise, causing Madam Pince to come running. He had to quickly run away while still under the cloak, and almost ran into Filch on his way out.
A great funny art idea for Harry Potter fanfiction would be to illustrate a story where Dumbledore decides to hold a talent show at Hogwarts. Draw Neville doing a really bad but hilarious magic act that goes completely wrong, like making his toad turn into a giant balloon toad that floats around the Great Hall. You could also create art for a fanfic where the portraits on the walls start gossiping about the students. Depict the Fat Lady and Sir Cadogan chatting and pointing at students as they pass by.
Once, Dumbledore's phoenix, Fawkes, decided to perch on Professor Snape's head during a particularly tense moment in the Great Hall. Snape couldn't do much about it as he didn't want to offend Dumbledore. His face was a picture of suppressed irritation while everyone else was trying hard not to laugh out loud.
The time when Fred and George Weasley put a Portable Swamp in the corridor was really funny. It caused chaos as students were trying to wade through the swamp, and the teachers were at a loss on how to get rid of it immediately.
Well, there are fanfics that bash certain characters in a funny way. Some might have Draco Malfoy slipping on banana peels every time he tries to be mean to Harry. In some fanfics, Filch might find himself chasing after a broom that has a mind of its own and keeps making fun of him. Also, fanfics where the Marauders play pranks on the teachers who are particularly strict can be really funny bashing fanfics.
Often, it's the unexpected situations. For example, if Ginny uses her magic in a really zany way around Harry, like accidentally turning his hair into a bunch of snakes or making his shoes fly off during an important moment. These out - of - the - blue magical mishaps add humor. Also, their relationship dynamic can be a source of comedy. If Ginny teases Harry about his famous - hero - complex in a really witty way, it can be quite funny.
One really funny Harry Potter fanfic is 'The Day Harry Potter Swapped Bodies with Ron Weasley'. Just imagine the chaos that ensues when two best friends suddenly find themselves in each other's bodies. They have to deal with each other's daily routines, from Ron trying to handle Harry's fame and Harry having to deal with the Weasley family dynamics in a very different way. It's full of laugh - out - loud moments.
