Another theme could be the exploration of the unknown. The lich is a rather mysterious and unearthly being in the Harry Potter universe. So, the fanfiction may focus on how the characters deal with this unknown entity, their curiosity, and their fear of the lich.
One main theme could be the battle between good and evil. Just like in the original Harry Potter series, but with the added element of the lich, which represents extreme evil. The story might show how Harry and his friends fight against the lich's dark intentions.
Well, he might become extremely powerful. A lich is often depicted as having great magical knowledge. Harry could learn dark and ancient magic that he wouldn't usually be exposed to at Hogwarts. His skills in combat and spell - casting could be enhanced to a whole new level, making him a much more formidable wizard against Voldemort or other threats.
Well, if Harry Potter becomes a lich in fanfiction, he would likely gain immortality. But he might also lose some of his humanity. His appearance would probably change, becoming more skeletal and undead - like. His magic could take on a darker, more necromantic tone.
No. Liches are often associated with dark and unethical magic. Harry has always been on the side of good and learning from a lich could corrupt his values.
Perhaps a wizard from Hogwarts gets transported to the world of the Lich King. He has to use his magic in new and unexpected ways to survive among the undead hordes. For example, he could use transfiguration spells to change the appearance of the undead, causing confusion among them.
Well, 'A Lich's Tale in Harry Potter's World' is also quite interesting. This fanfiction tells the story from the perspective of the lich itself. It gives a different view of the Harry Potter world, showing how a lich might interact with the characters we know and love. It has some really creative plot twists that make it stand out among other fanfictions.
One interesting 'Harry Potter the Lich Fanfiction' could be 'The Lich's Influence on Hogwarts'. It explores how the presence of a lich in the Harry Potter universe changes the dynamics at Hogwarts. For example, it might show how the lich's dark magic affects the students' learning and the professors' attempts to counter it.
The story could develop with Harry having to hide his new form from most of the wizarding world. Only a few close friends might know. He'd have to learn to control his new lich powers, which could be very dangerous if not properly harnessed.
One of the main themes is power and its consequences. When the Rinnegan, which is a very powerful ability, is introduced into the Harry Potter world, it often explores how having such power can affect the character's relationships and their place in the wizarding society.
Faith and hope are also prominent themes. The characters might find strength in their faith, whether it's in a higher power or in the goodness of others. For instance, when facing difficult situations like the threat of Voldemort, they hold on to hope and believe that good will ultimately triumph, which is similar to the Christian belief in God's plan and the victory of good over evil.
One main theme is the clash of different power systems. Since the Kyuubi has its own set of powers from the Naruto universe and Harry Potter has magic, seeing how they interact and sometimes clash is a big theme.
