In such a fanfiction, Harry Potter's transformation into a horse could be a part of a larger plot. For example, it could be related to a dark magic experiment that was meant for something else but accidentally affected Harry. His friends, like Hermione and Ron, would be in a frenzy trying to figure out how to turn him back. Hermione would likely be researching every book she could find on Transfiguration and dark magic. Ron, on the other hand, might be more focused on keeping Harry safe and comfortable in his new form. And Harry himself would be dealing with the shock and confusion of being a horse, all while still having his human mind intact and trying to communicate with his friends in whatever limited ways he can.
In this fanfiction, Beast Boy could turn into a girl because of an encounter with an alien artifact. As a girl, he discovers new aspects of his powers. Maybe he can now communicate with different animals in a more empathetic way. His relationships with the other Titans change too. Starfire might take her on shopping sprees, thinking she needs more 'girly' things.
One possibility could be that in this fanfiction, the transformation of Fem Harry into a Xenomorph might be the result of some dark magic gone wrong. Maybe she was experimenting with a spell that had unforeseen consequences. This would lead to a whole new set of challenges for her and the characters around her. Her friends would be shocked and have to figure out how to deal with this new, dangerous form she has taken on.
Perhaps in this fanfiction, Harry Potter turns into a horse during a Quidditch match. All of a sudden, instead of flying on his broom, he's galloping through the air. It would be a hilarious and chaotic scene. The other players would be so confused, and the spectators would be in shock.
Maybe it could be about the power of magic or a strange scientific experiment. In many fictional stories, there are elements that can cause such radical transformations. This could add an interesting twist to the plot as the boy-turned-girl has to navigate a world with a new body and identity.
There are some interesting kleptomaniac Harry Potter fanfictions out there. One aspect could be exploring how a kleptomaniac trait in a character, perhaps a new student at Hogwarts, might interact with the magical world's rules. For example, if they steal a magical item, it could lead to all sorts of chaos like accidentally activating a powerful spell or getting chased by magical creatures who protect the item. Another angle could be if a main character like Harry himself developed kleptomaniac tendencies, how would it change his relationships? Would Ron and Hermione still trust him? It could add a whole new layer of drama to the story.
In Harry Potter fanfiction, the Engorgio charm can be used in really creative ways. For example, some fanfictions might have a character accidentally use it on a small object, like a chocolate frog, and then have to deal with the chaos of a giant chocolate frog hopping around. It adds an element of humor and unpredictability to the story.
Sonic turning into a robot in fanfiction could also be a self - sacrifice situation. Suppose there's a powerful energy source about to explode and Sonic, in order to contain it, fuses with some nearby robotic parts. This would give him the ability to withstand the blast but at the cost of his normal form. His friends would be shocked at first but then try to find a way to restore Sonic. It could lead to an interesting adventure filled with emotions and high - stakes situations.
In a Hermione turns into a Nundu fanfiction, the story could start with Hermione feeling a strange connection to the Nundu in the magical creatures' book. She becomes so intrigued that she tries to perform a spell to understand it better on a deeper level. However, the spell mutates and she transforms into a Nundu. As a Nundu, she experiences the world in a completely different way. She can't communicate with her friends as she used to. Her friends would first be shocked and then start looking for solutions in every magical book and from every magical expert they know.
One possible scenario could be that Pikachu is exposed to a strange type of energy. This energy mutates its genetic structure, slowly transforming it into a human form. At first, Pikachu might be confused and scared, not understanding its new body. But as time passes, it starts to learn about human ways, like walking on two legs and using its hands to pick things up.
One possibility could be that Emma's transformation into a man is due to a magical spell gone wrong. Maybe she stumbles upon an ancient book in a dusty attic and reads an incantation not knowing what it does. As she turns into a man, she has to deal with a whole new set of physical and social challenges. For example, she might struggle with the different ways men are expected to dress and behave in her society.
