Well, it could start with a completely different backstory for Harry. Maybe he grows up in a more intellectually stimulating environment due to Mycroft's influence. His magic might be seen as an unusual form of intelligence in Mycroft's world. And there could be a lot of mystery around how his wizarding abilities interact with Mycroft's world of secrets.
Yes, there are likely fanfictions out there with this concept. Fanfiction writers often come up with creative and unexpected crossovers. However, the 'Harry Potter' and 'Mycroft' universes are quite different in nature, which makes this kind of fanfiction all the more interesting as it combines the magical world of 'Harry Potter' with the more mystery - filled and intellectual world often associated with Mycroft.
In a 'Harry Potter is the son of Thanatos' fanfiction, the story could start with Harry discovering his true parentage. This would likely lead to a whole new set of adventures. His character might become more brooding and less trusting, as he realizes he has this dark heritage. The wizarding world's reaction to him could be mixed, with some fearing his power and others seeing it as a potential weapon against the forces of evil. There could be a lot of exploration of the nature of death and how it relates to magic in the story.
He would probably be highly intelligent. Mycroft is known for his brilliant mind, and Harry would likely inherit that. He'd be able to analyze situations quickly and come up with solutions. Also, he might be more introverted compared to the original Harry. Mycroft is not a very outgoing person, so Harry could be more reserved, spending time thinking and planning rather than being in the spotlight all the time.
Definitely. Fanfiction writers love to experiment with different character combinations. Harry Potter, with his magical abilities and heroic nature, and Mycroft, with his intelligence and influence in his own universe, could make for a very interesting couple in a fan - created story. The fanfic might explore how their different backgrounds and skills would interact within a relationship, perhaps with Harry introducing magic to Mycroft's world or Mycroft using his wits to help Harry in new ways.
Well, it could be a really interesting story. Maybe Harry would inherit Mycroft's intelligence and use it in the wizarding world. He might solve magical mysteries in a more logical and deductive way, different from the usual magic - based solutions. For example, when dealing with the mystery of the Chamber of Secrets, instead of relying solely on spells and potions, he could use his Holmes - like reasoning to figure out who the heir of Slytherin really is.
One possible plot is that Harry's powers start to manifest in a different way than expected in the wizarding world. Because of his Poseidon connection, he can do things like make water flow upwards or create powerful water - based spells. The Ministry of Magic might be suspicious of him, thinking he's using dark magic. Meanwhile, he gets a visit from a messenger of Poseidon who tells him about his true father. Harry then has to balance his life in Hogwarts and his new responsibilities as Poseidon's son.
The plot could start with Harry accidentally stumbling into Mycroft's world. They initially clash due to their different ways of thinking, Harry being more impulsive from his adventures and Mycroft being calculating. But as they get to know each other, they find common ground in their desire to protect their respective worlds. Eventually, they fall in love and get married. Their marriage could then be a source of power as they combine Harry's magic and Mycroft's influence to face threats that cross over from different dimensions.
One possible plotline could be Harry using Mycroft's deductive skills to figure out the true nature of his parents' death earlier. He might not trust Dumbledore as blindly and instead start his own investigations.
In such a fanfiction, Harry might grow up with a high level of intelligence and deductive skills. Mycroft's influence could lead Harry to approach magic and the wizarding world in a more logical and strategic way, perhaps using his knowledge to solve magical mysteries that others overlook.
The plot could involve Harry growing up in an abusive situation in the wizarding world. When Tony Stark finds out he has a son, he takes Harry in. Harry has to deal with the new environment which is very different from Hogwarts. There could be a conflict between Harry's magical abilities and Tony's high - tech gadgets. Also, Harry might have trust issues because of his past abuse, which could create tension in his relationship with Tony and the other Avengers.
