In the world of fanfiction, there could be a story where Mal uses magic to look older because she wants to escape her current identity for a while. She might be tired of being treated as a young and inexperienced character. So, she magically ages herself to start anew. As for finding these fanfictions, start by looking at the tags and summaries on fanfiction platforms. Check for tags related to Mal, magic, and age - transformation. This way, you can narrow down your search and hopefully find some great fanfictions that explore this interesting concept.
One possible fanfiction could be where Mal is preparing for a top - secret mission that requires her to blend in with an older crowd. So, she uses her magic to age herself. However, I can't really point to a specific existing fanfiction off - hand. You could try searching on popular fanfiction websites like Archive of Our Own or FanFiction.net using keywords like 'Mal magic age older' to find relevant stories.
In 'The Witcher' series, magic is used for monster - slaying. Geralt uses signs (a form of magic) to defeat all kinds of terrifying creatures. Another example is in 'A Song of Ice and Fire', where there are rumors of magic that add an air of mystery to the story, like the red priestesses and their strange powers.
One reason could be for deception. Maybe she needs to trick an enemy into thinking she's an older, more experienced magic - user. So, she uses magic to look older.
I'm sorry, I don't have specific examples off - hand. But it could be something like Maleficent using her magic to heal Mal's broken wings. Or perhaps she uses a spell to heal Mal's broken heart after a betrayal.
I'm not sure of specific fanfictions where Hermione is depicted as a thief off the top of my head. But in some fanfiction, this might be part of a plot where she steals a powerful magical artifact to keep it out of the wrong hands, perhaps believing the Ministry or some dark forces are misusing or will misuse it.
Sure. In some fanfictions, Harry uses Parselmagic to unlock a secret passage that is guarded by snake - like spells. He simply speaks to the spell in Parseltongue and it allows him to pass.
I'm not sure specifically as there are countless fanfictions. But perhaps an example could be Harry using logic to figure out a hidden passage in Hogwarts that was previously only thought to be accessible by magic. He might analyze the architecture and come up with a non - magical way to open it.
One example could be a fanfiction where Hinata gets jealous whenever Naruto talks to other female characters. She might subtly try to keep Naruto's attention on her by always being by his side and giving disapproving looks when others approach him.
One example could be a fanfiction where Hermione is in a dangerous situation in the Forbidden Forest. Sirius, being protective, immediately apparates there to save her from a group of dark creatures. He uses his advanced magic skills to fend them off and then takes Hermione back to safety at Hogwarts.
One example could be that when Harry is faced with a magical creature that seems dangerous, instead of immediately trying to fight it with magic, he first observes its behavior to find a non - violent way to deal with it, like luring it away with food. This shows his use of common sense.
One example could be that Naruto uses Yin Release to create a genjutsu that makes an entire battlefield seem like a peaceful meadow to his enemies, causing them to lower their guard.
