Another popular character could be Draco Malfoy. His family's influence and his own complex character make him an interesting candidate for exploring wandless magic. In fanfic, he might be forced to use wandless magic in a situation where his pure - blood ideals are challenged, and through this, he could have a character arc that shows growth and a new understanding of magic.
Dumbledore is another character often seen in these fanfictions. His great power and wisdom make it believable that he has dabbled in wandless magic. Fanfic writers might explore how he used it in his younger days or how he secretly taught others. Also, Voldemort could be involved, as his pursuit of ultimate power could lead him to explore the boundaries of wandless magic, perhaps seeing it as a way to gain an edge over his enemies.
I also like 'Unleashing the Wandless'. In this fanfic, the main character is an outcast because of his interest in wandless magic. But he soon finds out that there are others like him. The story is about their journey to prove that wandless magic can be as powerful, if not more, than traditional wand - based magic.
Obviously, Harry Potter is a main character as the title suggests. He is the one who is on the journey of learning wandless magic. Hermione Granger could also be an important character. She might be helping Harry research about wandless magic, using her vast knowledge from the library.
One of the most impressive feats could be large - scale teleportation. In some fanfictions, Harry Potter manages to transport himself and others over long distances without a wand, which is extremely difficult magic even with a wand. Another could be instantaneously conjuring complex magical shields to protect against powerful dark spells, all wandlessly.
Harry Potter himself is often a popular character in such fanfic. His magical abilities and heroic nature make him a central figure that can easily be incorporated into the Magic Tree House adventures.
In some fanfictions, Harry Potter might develop his wandless magic skills through intense mental training. He could practice focusing his magic without the aid of a wand, much like how he learned to control his Patronus. By visualizing the desired outcome clearly in his mind and concentrating his magical energy, he gradually becomes proficient at wandless magic.
In 'Wandless Magic' fanfic, a cool idea is that it can break the boundaries set by the Ministry of Magic. Since wands are registered and regulated, wandless magic gives characters a sense of freedom. They can perform magic secretly, away from the prying eyes of the Ministry. This can lead to all sorts of exciting plotlines, such as underground magic societies where wandless magic is the norm.
The idea of wandless magic in fanfics is appealing because it offers a new perspective on the Harry Potter magic system. It allows for more creativity and exploration of characters' raw magical abilities, without the limitations of wands.
Harry Potter himself is very popular. Since he's the main character of the original series, many fanfics revolve around him, either continuing his story or changing certain aspects of it. Hermione Granger is also a favorite. Her intelligence and strong - willed nature make her a great character to explore further. Draco Malfoy is another popular one. Writers often like to redeem his character or explore his inner thoughts and struggles.
Harry himself is also very popular. Given his status as the Boy Who Lived, fanfiction writers like to put him in situations where he has to use star magic to defeat new and powerful enemies. It adds a new dimension to his already heroic character.
