Who would be the most interesting character pair in a Harry Potter and Fairy Tail crossover fanfiction?

Dumbledore and Carlisle Cullen would also be a fascinating pair. Dumbledore is a wise and powerful wizard, and Carlisle is an old and moral vampire. They could have deep discussions about life, death, and the responsibilities that come with their powers. They might also collaborate to find solutions to problems that affect both their worlds.

Goku and Natsu would be an interesting pair. Goku is always looking for a strong opponent to fight and improve his skills. Natsu, on the other hand, is a hot - headed but powerful wizard. Their fighting styles are quite different. Goku relies on his martial arts and ki abilities, while Natsu uses his fire dragon slayer magic. They could learn a lot from each other. For example, Goku could teach Natsu about physical conditioning, and Natsu could show Goku some unique magical techniques.

Pairing Ben with Natsu would be really interesting. Natsu is all about fire and brute strength, while Ben has a wide range of alien powers. They could learn a lot from each other. Ben could show Natsu some high - tech gadgets and Natsu could introduce Ben to the world of magic. Their different personalities, Natsu's hot - headedness and Ben's more laid - back nature, would also create great chemistry.

Lucario and Gajeel could also be an exciting pair. Gajeel is a tough and aggressive fighter, and Lucario is no slouch either. They could have some intense battles together against common enemies. Lucario's aura - sensing could help Gajeel anticipate his opponents' moves better, and Gajeel's metal - based attacks could provide a different kind of offensive power that Lucario hasn't encountered before. Their personalities, both being a bit headstrong in their own ways, could lead to some interesting character development as they learn to work together.

Harry Potter and Gordon Freeman would be a really interesting pair. Harry has his magical powers and knowledge of the wizarding world, while Gordon has his scientific know - how and combat skills. They could learn a great deal from each other. Harry could show Gordon the wonders of magic, like how to Apparate or use the Invisibility Cloak. Gordon could introduce Harry to the concepts of advanced physics and technology in the Half - Life universe, like how the Gravity Gun works.

I think Harry and Akane would be an interesting pair. Harry has his own set of challenges dealing with Voldemort and the wizarding world, and Akane has to deal with Ranma's antics. They could share their experiences of having someone important in their lives who can be a bit of a handful. And they could also learn from each other's fighting styles, Harry with his magic and Akane with her martial arts.

Another great pairing could be Ron and Fry. Ron is a bit of a laid - back character who often follows Harry's lead, while Fry is a strong - willed woman. Fry could encourage Ron to be more independent and take charge. Ron could introduce Fry to the concept of magic, which she would find both amazing and a bit hard to believe at first. Their relationship could be a source of both comedy and growth in the fanfiction.

Ron and Nick Burkhardt would be an exciting combination. Ron has his loyalty and his skills with magic, while Nick has his detective skills and his ability to handle Grimm situations. They could go on adventures together, with Ron using magic to help Nick in tight situations and Nick using his street smarts and Grimm knowledge to guide Ron through the non - magical aspects of the Grimm world.

Hermione Granger and Sakura Haruno could make a great pairing. Hermione is known for her intelligence and thirst for knowledge, and Sakura is a smart and determined kunoichi. They could exchange medical knowledge, Hermione's knowledge of potions and Sakura's ninja medical skills. They could also bond over their shared experiences of being part of a team and having to prove themselves in a male - dominated environment.

Ron Weasley and Joey Wheeler would be a fun pair. Ron is often the more laid - back and comical sidekick in Harry's adventures. Joey is also a bit of a hot - headed and humorous character in Yu - Gi - Oh!. They could get into all sorts of misadventures together. Maybe they start a small - scale Duel Monsters tournament within Hogwarts and cause a bit of chaos as they try to figure out the rules and make it work in the wizarding world.
