One possibility could be that Harry has some extraordinary powers inherited from Shiva. Maybe he can control certain elements like fire or water in a more divine way. For example, his Patronus could take on a form related to Shiva's symbols, like a Nandi (Shiva's bull).
The story might explore how the wizarding world reacts to Harry being the son of Shiva. Some might be in awe, seeing him as a new kind of powerful being. Others could be fearful, worried that his powers are too different or uncontrollable. Dumbledore, for instance, would likely try to guide Harry in understanding and using these new powers for good.
In this fanfiction, the magical creatures could also be affected. Harry might have a special connection to magical beasts that are associated with Shiva in Hindu mythology. He could communicate with them on a deeper level. And his relationship with Voldemort would be very different. Voldemort might be even more envious of Harry's newfound and extremely powerful heritage, leading to more intense battles between them.
In this fanfiction, perhaps Harry would inherit some of Hestia's qualities. Hestia is the goddess of the hearth, so Harry might have a strong sense of home and family. He could be a more nurturing figure, different from his canon self. His magic might also be influenced by Hestia's domain, like having an affinity for protective spells related to the home.
Well, it could be a story full of magical and mythological crossovers. Harry might have powers from both the wizarding world and his newfound heritage as the son of Zeus. He could control lightning like Zeus, adding a new dimension to his battles against Voldemort. Maybe he would also have some sort of connection to the Greek gods' realm, and they could interfere in the wizarding war in unexpected ways.
It could be really interesting. Harry Potter is from the wizarding world of Hogwarts, and Athena is from Greek mythology. In this fanfiction, perhaps Harry would inherit some of Athena's wisdom. He might use it to solve the mysteries in the wizarding world more cleverly, like he could figure out Voldemort's plans faster. Also, his connection to Athena could give him an edge in battles, maybe with some sort of strategic magic.
One possibility could be a story of internal conflict for Harry. He might struggle with the dark heritage from Tom Riddle while trying to uphold the values of the wizarding world he has grown to love. He could constantly battle his own darker instincts that come from being Voldemort's (Tom Riddle) son. For example, he might have an in - built talent for Parseltongue that he has to learn to control and use for good instead of evil.
One possibility is that Harry would grow up with a very different set of skills. Artemis is associated with the hunt and nature. So Harry might be an excellent tracker and have a deep connection with animals. He could learn archery from a young age and be more in tune with the wild. His magical abilities might also be influenced in a unique way, perhaps with spells related to nature being more accessible to him.
In this fanfiction, Harry could be on a quest to protect dragons. Given his kind heart, he might learn about the cruel treatment of dragons in some parts of the wizarding world, like in dragon - breeding for the Triwizard Tournament. So he decides to take a stand and try to ensure their well - being. This could lead to him making new friends or enemies in the process, and exploring new parts of the wizarding world that are related to dragons.
Well, it could involve Harry growing up with the Delacour family's unique culture. Maybe he'd learn different kinds of magic that the Delacours are known for. He might also have a different personality, influenced by their flamboyant and refined ways.
In a story where Harry is raised by a boggart, he could have a very distorted view of the world. The boggart, not being a normal caregiver, might not be able to provide the love and stability that a normal family would. So, Harry might be more withdrawn and distrustful. He might also have a hard time making friends at Hogwarts as his upbringing by a boggart could have made him seem strange to other students.
The story could show Harry being an outcast among wizards at first because of his mermaid - influenced behavior. For example, he might not understand some of the basic social norms in the wizarding world. However, his mermaid - raised skills could also make him a very powerful wizard in certain areas, like water - based spells or divination related to the sea.
In a Fem Harry Potter is Enkidu fanfiction, it might show Fem Harry Potter idolizing Enkidu. She could study the stories of Enkidu and try to incorporate some of his values into her life in Hogwarts. Since Enkidu was known for his strength and his relationship with Gilgamesh, Fem Harry Potter could perhaps form a similar strong bond with one of her friends, like Hermione or Ron, inspired by Enkidu's story.
