Well, perhaps Harry Potter accidentally casts a spell that opens a portal to the underworld. He meets Hades, who is curious about this boy with strange powers. Hades offers Harry a deal. If Harry can solve a series of riddles and challenges within the underworld, Hades will give him a powerful artifact that can help protect the wizarding world from future threats. Harry accepts the challenge and during his journey, he meets various mythical creatures and overcomes many obstacles with his Hogwarts - taught magic and his own wits.
A plot might involve Harry Potter being sent to the underworld on a quest. Hades mistakes him for a threat at first. But as Harry shows his courage and resourcefulness, Hades starts to respect him. They could end up working together to stop a dark force that is threatening both the wizarding world and the underworld. Harry could teach Hades some magic spells, and Hades could show Harry the hidden powers of the underworld.
Well, perhaps Harry is a secret demigod of Hades all along. The story could start with strange things happening around Harry that he can't explain. As he delves deeper, he finds out his true nature. He then has to balance his life in the wizarding world with his newfound demigod status. He might face opposition from both wizards who don't trust this new side of him and other demigods who are jealous or think he doesn't belong. And in the end, he uses his combined powers to save both the wizarding world and the demigod realm from a common threat.
The plot might involve Harry being drawn to the underworld. He could be visited by spirits or have strange dreams that lead him to suspect that he has a connection to Hades. As he investigates, he uncovers secrets about his mother or father that were hidden from him. This could also tie into the existing plot of the Harry Potter series, where Voldemort might be interested in Harry's new connection for his own evil purposes. For example, Voldemort might think that by controlling Harry, he can gain access to the power of the underworld.
In this fanfiction, the plot might start with Harry Potter finding himself in a strange situation where he becomes a street boss in a world that has elements of Hades' domain. He could be using his skills from Hogwarts, like his dueling abilities and knowledge of spells, in a more gritty and unorthodox way. For example, he might use spells to intimidate or control the people in his 'street territory'. There could be a complex web of relationships where he has allies who help him in his new role, but also enemies who are out to get him. As the story progresses, he might face internal struggles as he strays further from the values he learned at Hogwarts, all while trying to stay on top in this dangerous new world.
Well, the plot could involve the demigod son of Hades using his powers in the wizarding world. He might struggle with being different from other wizards because of his demigod heritage. For example, he could have the ability to control the dead, which would be both a great power and a source of fear among his peers. Maybe he gets involved in a mystery that only his unique skills can solve, like a dark magic related to the underworld.
The plot might involve Harry being drawn to the Forbidden Forest because of her Hades heritage. There could be a portal or some sort of underworld connection there. She could encounter dark creatures that are more in tune with her underworld side. And she might have to use her new - found powers to save Hogwarts from a threat that has roots in the underworld. For example, a powerful dark wizard is trying to raise an army of the dead and only Harry, with her connection to Hades, can stop it.
One possible plot could be that Harry Potter discovers a magical portal that leads him to the underwater world of Aquaman. There, he has to learn the ways of the underwater society while also using his magic to help Aquaman fight against an evil force that threatens both the wizarding world and the underwater realm. Maybe a dark wizard has teamed up with a sea - based villain, and Harry's unique skills are needed to defeat them.
One possible plot could be that Alduin somehow enters the Harry Potter universe. Maybe he is summoned by a dark wizard who wants to use his power to take over Hogwarts. Harry and his friends then have to figure out how to send Alduin back to his own realm while also dealing with the chaos the dragon has brought to the school.
One possible plot could be that Boromir somehow gets transported to the wizarding world of Harry Potter. He could be mistaken for a Muggle at first, but his warrior skills and strong sense of honor quickly earn him respect. Maybe he joins the Order of the Phoenix and uses his combat experience to fight against the Death Eaters. He might also form an unlikely friendship with Harry, learning about magic and teaching Harry about his own world's combat strategies in return.
Well, it could start with Harry having strange dreams or visions about his real parents. As he investigates, he uncovers the truth. His story could then revolve around him trying to unite the two very different worlds of his parents. He may face challenges from both the Greek gods and the wizards. For instance, Zeus might see him as a potential threat as the son of Hades and try to stop him. In the wizarding world, the Ministry of Magic might fear his new - found powers. Harry would need to learn to control his powers from both Artemis and Hades. He could have a special weapon or tool given to him by his parents, like a bow from Artemis that can shoot magical arrows or a key to the underworld from Hades that gives him access to certain dark magics which he must use for good.
One possible plot could be that Voldemort uses the dark magic to create a plague similar to the one in The Walking Dead. The wizards and witches have to not only fight against the undead but also Voldemort's forces. Harry and his friends would need to find a way to stop the spread of the plague and defeat Voldemort once and for all, while also learning how to survive in a world filled with the walking dead.
