What are the most unique concepts in Harry Potter and Green Arrow fanfiction?

Some fanfictions feature unique magic related to memory manipulation. Instead of just using the Obliviate spell, there could be a more complex form of magic where one can not only erase but also rewrite memories in great detail. There might also be a type of magic that is based on the constellations, where wizards can draw power from the alignment of the stars. Additionally, a unique magic could be the ability to transform into mythical creatures, not just the Animagus transformation we know from the books, but into something more fantastical like a phoenix or a dragon.

In Harry Potter different fanfiction, a really interesting concept is time - travel related ones. Imagine if Harry went back in time to change certain events in the wizarding world's history. It could completely change the course of the story. Some fanfictions also play with the idea of different magical cultures around the world interacting with Hogwarts. This could lead to new spells, new forms of magic, and new adventures for the characters.

A really unique fanfiction concept could be one where Snape and Harry time - travel. They go back to key moments in wizarding history and have to work together to fix things that went wrong. This would be an exciting adventure and would force them to rely on each other.

Some fanfictions explore the idea of wands having emotions. For example, in 'The Sentient Wand', the wand can feel joy, sadness, and even love towards its owner. This changes the dynamic of how the wizard - wand relationship is perceived.

There are often fanfictions that blend different universes like this. In some, Green Arrow's modern - day gadgets and skills might seem out of place in the magical world of Harry Potter at first. But then, the author might find a way to make it work, like his arrows being enchanted or having special properties that can counter dark magic. It's really all about the creativity of the writer.

One more unique aspect is the potential for new magical creatures or entities. Since green magic is associated with nature, fanfiction writers can introduce new nature - inspired magical beings. These could be spirits of the forest, or sentient plants that can interact with wizards. It also allows for new plotlines centered around protecting these new entities or using their power for good. This adds a whole new layer of creativity and mystery to the Harry Potter fanfiction world.

Well, there could be a concept where a monster girl is actually a guardian of a hidden part of the Forbidden Forest. She has to interact with the Hogwarts students who accidentally stumble upon her territory. Or perhaps a monster girl who is a half - vampire and is struggling with her thirst for blood while also trying to fit into the wizarding world. There are also ideas like a monster girl made of living plants who has a connection to the Herbology department at Hogwarts.

Well, some fanfics have the idea of a time - traveling Defense teacher. For example, a character from the future comes back to teach the subject. This brings in new spells and ways of fighting dark magic that the students haven't seen before.

One unique concept could be a new form of jutsu that combines the power of the Sharingan with a green - themed chakra. Maybe it's a nature - based jutsu that only those with the green Sharingan can use.

One interesting plot twist is when the bow and arrow are actually a key to an ancient wizarding prophecy. In a particular fanfic, Harry finds this old, dusty bow in a hidden chamber. Little does he know that it's tied to a prophecy that could change the fate of the wizarding world. It's a great twist because it takes something as simple as a weapon and turns it into a major plot device.
