Another theme is identity. Harry being a lightning mage sets him apart from the normal wizard. He has to figure out how this new aspect of himself fits into his identity as the Boy Who Lived. In some fanfictions, he may face discrimination or envy from other wizards because of his special power.
Power and control are common themes. Since Harry has this unique lightning magic, he often has to learn to control it, which can be a struggle. For example, in many fanfics, his initial outbursts of lightning magic can be dangerous and unpredictable.
The theme of self - discovery is quite common too. Harry has to figure out what it means to be a battle mage and how it changes his identity. He may struggle with the idea that he is different from the normal wizard, and this internal conflict is often explored. Additionally, the idea of protecting Hogwarts and the wizarding world in a more proactive way, using his battle mage skills, is a prevalent theme in many 'Harry Battle Mage' fanfictions.
One common theme is power. Often, Harry as a mage has greater or different powers compared to regular wizards. Another theme is discovery, like finding out about the mage world within the wizarding world. And there's also the theme of isolation, as Harry might be the only mage or one of few in Hogwarts.
One common theme is the exploration of the forbidden nature of blood magic. Since it's often seen as dark magic in the Harry Potter universe, fanfictions may focus on how Harry copes with the stigma associated with it.
I'm not sure specifically as it could be a very unique take. It might be a fanfiction where Harry Potter is reimagined as a lightning mage, perhaps with new powers related to lightning and different adventures based on that new role.
One common theme is the use of lightning as a powerful and dangerous magic. In many fanfictions, a character might have the ability to control lightning, which often makes them a force to be reckoned with. It could be used in battles, either defensively or offensively. For example, they might send bolts of lightning towards their enemies to defeat them. Another theme could be the connection between lightning and a character's inner power or emotions. A character who is angry or in a state of high emotion might accidentally or purposefully unleash lightning magic.
One common theme is the struggle of being different. The ice mage often has powers that are not like the normal magic in the Harry Potter universe, so they face discrimination or misunderstanding.
One common theme is gender role exploration. Since Harry is female in these fanfictions, it often looks at how she navigates a male - dominated wizarding world. For example, how she might face different expectations in dueling or in classes like Potions.
The unique magic concept. Lightning magic is different from the regular spells in Harry Potter. It adds a new element of power and danger. For example, a lightning mage could summon bolts of lightning during a battle, which is much more intense than a simple Stupefy spell.
Well, often you'll find themes of self - discovery. Harry as a mage is constantly learning about himself and his place in the magical world. Mystery is also a big one. Fanfics might have a mystery surrounding a new magical power or a strange event. And of course, the battle between good and evil is a common theme, with Harry as a mage being on the side of good.
Another theme is the power of hope. Given their circumstances in the game, many fanfictions use their story to show how hope can keep them going even in the darkest of times. For example, Serah might be a symbol of hope for Lightning in some stories. Also, the theme of sacrifice is quite common. Lightning is often depicted as being willing to sacrifice a great deal for Serah's safety and well - being.
