Fanfiction about Harry Potter and a Gun Mage: What are some interesting plot ideas?

A plot could involve Harry being trained in an ancient art that combines mage and warrior techniques. He then has to use these skills to protect Hogwarts from a new threat that is immune to normal magic. He might have to physically fight and use magic at the same time, like creating magical shields while engaging in hand - to - hand combat.

Maybe there could be a plot where an ancient evil threatens the wizarding world, and only an elemental mage can stop it. The elemental mage has to go on a quest to master all elements fully. They start with their native element, say water, and as they journey, they meet different characters from the Harry Potter series who help or hinder their progress in learning to control earth, air, and fire as well.

One idea could be a mage who can communicate with dragons and uses this ability to help Harry Potter in a secret mission. For example, the mage could get the dragons to guard Hogwarts during a big attack.

Perhaps a story where a battle mage is actually an undercover agent from a rival magical school. They are sent to Hogwarts to steal some powerful magic artifacts but end up having a change of heart. They might start to see the good in Hogwarts and its students and have to fight against their original mission.

Well, in some fanfictions, there are mages who can perform transfiguration on a much larger scale than what we see in the books. For instance, they can transfigure entire buildings into different structures. Also, there could be a plot where a mage's transfiguration abilities are linked to their emotions, so when they are angry, their transfiguration goes haywire. And then there are those fanfictions where a mage is trying to reverse a transfiguration spell that has gone wrong for decades, which makes for a really exciting read.

One idea could be Norberta getting lost in the Forbidden Forest and Harry has to find her. Another could be Norberta growing ill and Harry, with his knowledge of magical creatures, tries to heal her. Maybe Norberta could get into trouble with some other magical creatures and Harry has to step in to protect her.

One idea could be a story where a character has a special power to resist Dementors' effects more than others. Maybe they discover a hidden spell or have a unique magical ability that they use to fight off Dementors when others are in danger. For example, a young witch or wizard who can emit a positive energy that counteracts the Dementors' despair.

Perhaps Orochi is a hidden figure in the history of the wizarding world that has been forgotten. Harry discovers some old texts in the Hogwarts library that mention Orochi in relation to a long - lost magical artifact. This leads him and his friends on a quest to find the artifact before it falls into the wrong hands, as it has the power to either control Orochi or be used by Orochi to gain ultimate power over the wizarding world.

One idea could be that the scarecrow comes to life and becomes a magical creature that helps Harry Potter in a dangerous task. Maybe it has the ability to sense dark magic and warns Harry of approaching threats.

One plot idea could be that Harry and Angelina team up for a special Quidditch training session for the younger students. They discover a new flying technique together that gives Gryffindor an edge in future matches. Another could be that they go on a secret mission within Hogwarts to uncover a hidden artifact that has been causing strange magical disturbances. And a third idea is that Angelina gets injured during a match and Harry uses some of his unique magical skills, learned from his various adventures, to help her recover faster than normal.
