Fanfic ideas combining Harry Potter and a Space Captain
One idea could be that the Space Captain crash - lands on the magical world of Harry Potter. He has to learn about magic to repair his ship while Harry and his friends are intrigued by the advanced technology the captain brings. Maybe they team up to fight a new threat that is endangering both the wizarding world and the space captain's galaxy.
In a fanfic, the Space Captain could be from a parallel universe where magic and space travel co - exist. He hears about the power of the Harry Potter universe and decides to visit. He offers to take Harry and his friends on a space adventure. During this adventure, they discover a dark wizard who has escaped to space and is causing chaos among different alien species. Together, they use magic and space - age weapons to defeat the wizard.
A possible fanfic could involve a Space Captain who is actually a descendant of a wizard who left the Harry Potter universe long ago. He has some latent magical abilities but is mainly focused on his space career. When his ship gets pulled into a magical anomaly, he ends up in the world of Harry Potter. There, he meets Harry and they realize they have a common enemy. The Space Captain's knowledge of different galaxies and Harry's magical skills combine to take on this powerful foe.
Fanfiction ideas combining Harry Potter and Captain Cold
One idea could be a crossover where Captain Cold somehow ends up in the wizarding world. Maybe he's on the run from the Flash and uses a magical artifact in Central City that zaps him into Hogwarts. He could initially be seen as a threat but then team up with Harry Potter to fight a common enemy, like a dark wizard who has acquired some sort of technology -mixing magic and science in a dangerous way.
Fanfic ideas combining Harry Potter and Wendigo
One idea could be a story where a Wendigo somehow enters the wizarding world of Harry Potter. Maybe it's brought in by a dark wizard who wants to use it as a weapon. The Trio - Harry, Ron, and Hermione - would then have to figure out how to defeat it using their magic and knowledge.
Fanfic ideas combining Harry Potter and Hulk?
One idea could be that Hulk somehow gets transported into the wizarding world of Harry Potter. Maybe a magical experiment gone wrong by a Hogwarts student creates a portal that sucks Hulk in. He could then cause chaos as he's not used to the magic and strange creatures there.
Fanfic Ideas Combining Harry Potter and Justice League
Another concept is that the magic from the Harry Potter series starts to seep into the DC universe where the Justice League operates. This causes chaos as the laws of physics in the DC world are disrupted. The Justice League has to seek help from Hogwarts professors to understand and contain this new form of magic energy. Superman might be intrigued by the idea of magic being a new power source or a new threat he can't easily overcome with his super strength.
Fanfic ideas combining Harry Potter and Tony Stark
One idea could be that Tony Stark somehow discovers the wizarding world while working on a new technology. Maybe his sensors pick up some strange magical energy. He then meets Harry Potter and they team up to face a new threat that combines magic and technology, like a dark wizard using Stark Industries' tech for evil purposes.
Fanfic ideas combining Harry Potter and King Arthur
One idea could be a fanfic where Harry Potter discovers a hidden portal in Hogwarts that leads him to the time of King Arthur. He could use his magic skills to assist Arthur in battles, perhaps using spells to defeat the enemies that Arthur's knights struggle with. For example, Harry could use the Stunning Spell to incapacitate a large group of invaders.
Fanfic ideas combining LotR, Harry Potter and nanomachines?
One idea could be to have nanomachines in the Harry Potter universe that are secretly created by a dark wizard. They could be used to control the minds of students, but the protagonists discover this and use magic inspired by LotR spells to combat it. For example, a Patronus charm with a LotR - like incantation to repel the nanomachine - influenced dark magic.
Fanfic ideas combining Harry Potter and Alma Wade
A third fanfic concept could involve a character from the Harry Potter series stumbling into Alma Wade's world. Let's say Hermione accidentally discovers a portal that leads to Alma's realm. She has to use her knowledge of magic and her wits to survive in this strange new place. Meanwhile, Alma Wade is intrigued by Hermione's magic and they start to learn from each other, with Hermione introducing wizarding spells and Alma sharing her unique powers.
Fanfic ideas combining Harry Potter and Stargate Atlantis
One idea could be to have the wizards from Harry Potter's world discover the Stargate Atlantis technology. Maybe they could use magic to help repair or understand some of the advanced technology in Atlantis. For example, Hermione could use her vast knowledge of spells and ancient runes to decipher the Atlantis control panels.
Fanfic Ideas Combining Arrancar, Ichigo, and Harry Potter
One idea could be a crossover where Ichigo, with his Soul Reaper powers, is somehow transported to the Harry Potter universe. He meets some of the Arrancar there who have also found their way into this new world. They could be causing chaos, and Ichigo teams up with Harry Potter and his friends to stop them. Maybe the Arrancar are attracted to the magic in the Harry Potter world and want to harness it for their own power.
