Maybe something like moonstone dust for its lunar connection which could symbolize femininity, and dragon scales which are often associated with masculinity in the 'Harry Potter' lore. Add a bit of unicorn hair for purity, and a drop of mermaid tears to give it that magical touch.
Well, it's quite possible. Given the magical nature of the 'Harry Potter' universe, a gender reveal potion fits right in. There are fanfictions that explore all sorts of unique magical concepts. However, not all fanfictions are easy to find. You might have to dig a bit deeper, use specific search terms related to the potion, the characters you think might be involved in such a story, etc. on the fanfiction platforms.
Some cool potion ingredients in Harry Potter fanfiction are the fangs of a werewolf. These could potentially be used in a potion to control the werewolf transformation or to gain some of the werewolf's enhanced senses. Moonstone dust is also a great one. It has a connection to the moon and in fanfiction might be used in potions related to lunar magic, like a potion that only works during a full moon. And let's not forget the blood of a vampire. It's a rather dark ingredient, but in fanfiction it could be used in a potion to gain immortality or some form of dark power, although using it would likely be very controversial in the wizarding world.
Often, there is also a theme of self - discovery. Characters may use the gender potion not just for fun or by accident, but as a way to understand themselves better. They might learn about their own strengths and weaknesses from the perspective of a different gender, and this can be a powerful part of the fanfiction's narrative.
Fanfiction writers get really creative with potion ingredients. They often take an ingredient like the powdered horn of a unicorn. Instead of just using it for its normal purpose of making potions for healing or enhancing magic, they might use it in a potion that, when drunk, allows the wizard to enter a different dimension or time period. Another way is by re - imagining the way ingredients are sourced. For instance, the bile of a Blast - Ended Skrewt. In fanfiction, instead of it being a by - product of the Skrewt's normal functions, it could be something that is magically extracted in a very elaborate and dangerous ritual, and this special bile could be used in a potion for extreme strength. Writers also like to create new ingredients based on the existing ones. They could take the concept of a shrivelfig and create a 'giant shrivelfig' whose juice is used in a potion to make things grow or shrink at will.
In some Harry Gathees fanfiction, common potion ingredients might include unicorn hair for its magical purity. It can add a powerful and positive essence to potions. Another could be mandrake root, which is often used in more complex and dangerous potions due to its volatile nature. And moonstone dust, which is said to enhance the magical properties related to the moon, like divination potions.
In the original Harry Potter series, potion ingredients are mostly traditional and well - known within the wizarding world. But in Harry Gathees fanfiction, they might be more exotic. For example, in the original, we have things like powdered bat wings. In fanfiction, there could be the wings of a magical hybrid creature. Also, the uses of the ingredients can be more creative in fanfiction. While in the original, dittany is mainly for healing, in fanfiction it could be a key part of a potion to enhance a wizard's charm.
Well, he might create some unique potions. Maybe a potion that can make people temporarily have the ability to speak Parseltongue. It would attract a lot of curious wizards and witches to his shop.
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.
Well, someone might end up with a really strange combination of features. For example, they could have the body of one character but the voice of another completely different character. It could lead to all kinds of misunderstandings. Maybe they try to blend in with a group but because of the mess up, they act in a way that gives them away immediately.
One possible plot could be that Tonks accidentally creates a potion that makes her swap appearances with Harry. This would lead to a series of comical and confusing situations. For example, Tonks (in Harry's body) has to deal with Harry's friends not realizing it's her, and she has to figure out how to reverse the effect while also not getting Harry into trouble at Hogwarts. Meanwhile, Harry (in Tonks' body) has to navigate the world of the Order of the Phoenix and deal with Tonks' responsibilities.
