Maybe he would be an inventor. Harry has shown great resourcefulness throughout his adventures in the wizarding world. He could combine his magic with Stark's technology to create new and amazing inventions. For example, a device that uses magic to teleport people within the Stark Industries' complex.
He could be a consultant for magical - related matters. Since Stark Industries often deals with cutting - edge and dangerous technology, Harry's knowledge of magic could help in areas like security. For instance, he could use spells to detect and prevent magical infiltration into Stark's labs.
Harry might also play a role as a trainer. He could train Stark Industries' employees in dealing with magical threats or in using magical items if they ever come across them in their work. His experience in teaching at Hogwarts could come in handy in this regard, as he would know how to convey complex magical concepts to non - magical people.
Perhaps in a multiverse scenario. There could be a universe where the wizarding world and the Marvel universe collide. Harry Potter, being a skilled wizard, could be recruited by Stark Industries for his unique skills. He might use his spell - casting abilities to assist in research, like creating new materials with magic that could be used in Stark's high - tech gadgets.
He'd be a really cool mix. He'd probably be more confident and tech - savvy. Since Tony Stark is his dad, he'd have that Stark charm and arrogance a bit. He'd still be brave like in the original, but he'd also be more innovative in his use of magic, maybe combining it with some technology.
He could be a security specialist. With his magic skills like the Patronus charm which can repel Dementors, he could use similar magic to keep Stark's facilities safe from intruders. His ability to apparate and disapparate could also be useful for quickly moving around the compound and responding to threats.
It would be really interesting. Harry Potter is from a world of magic and Tony Stark is a technological genius. Harry could use his magic to assist Stark in ways that normal technology can't. For example, he could use spells to quickly repair damaged Iron Man suits or detect threats that Stark's sensors can't pick up. Stark, on the other hand, would introduce Harry to advanced technology which could open up new possibilities for the wizard. He might even try to figure out how to incorporate magic into his tech, creating some really unique and powerful inventions.
It depends on the situation. In the wizarding world, Harry Potter would be more powerful as he can use magic which is a fundamental part of that universe. He can cast spells to defeat enemies, protect himself and others, and manipulate the environment around him.
At the start, Tony could be a bit skeptical of Harry's abilities. But when Harry shows off a spell, like making a Patronus, Tony would be impressed. They would then start to work together. Harry could use his magic to help Tony get into places that are otherwise inaccessible, and Tony could provide Harry with some cool gadgets. For example, Tony could give Harry a device that helps him communicate with the wizarding world more easily. They would learn from each other and form an unlikely friendship.
He could be a powerful antagonist. Since Anubis is associated with death in Egyptian mythology, he might be interested in the power of the Deathly Hallows. He could try to steal them from Harry, believing they would give him more control over death in the wizarding world.
In a lot of Harry Potter fanfiction, Cerberus can be a plot - driving element. Its presence can create tension and suspense. For example, if a group of characters need to retrieve something from a place guarded by Cerberus, they have to figure out how to get past it. This can lead to all kinds of creative solutions and adventures in the story. It might also be used as a way to show the different magical abilities of the characters as they attempt to deal with it.
They can also be mentors. They have a great deal of knowledge about magic, nature, and the stars. In fanfiction, a centaur could take a young wizard or witch under their wing, teaching them things that they wouldn't learn in Hogwarts. This could include ancient spells or ways of communicating with nature. Moreover, centaurs can act as protectors. If there's a threat to the Forbidden Forest or Hogwarts, they might step in to defend it, using their strength and archery skills.
Ghouls can play the role of a minor threat. They might be the cause of some small scares for the characters, like making strange noises in the middle of the night. For instance, in a fanfic where a young wizard is exploring an abandoned manor, a ghoul could be hiding in the cellar, and when the wizard gets close, it growls menacingly.
