A combination of Sephiroth and Voldemort would be extremely interesting. Both are powerful and malevolent characters in their respective universes. Sephiroth's god - like complex and his pursuit of power could mesh well with Voldemort's desire for immortality and domination. Their combined forces would be a terrifying threat, and seeing how the heroes from both worlds would deal with them would be a great plotline in the fanfiction.
I think Aerith and Hermione would be a really interesting combination. Aerith has her connection to the planet and her gentle nature, while Hermione is highly intelligent and resourceful. They could combine their knowledge, with Aerith teaching Hermione about the life force of the planet and Hermione sharing her vast magical knowledge. It would be a great exchange of ideas and skills.
I think Mr. Incredible and Hagrid would be a really interesting combination. Mr. Incredible's no - nonsense attitude and his physical strength combined with Hagrid's love for magical creatures and his knowledge of the wizarding world would make for some great interactions. They could both be involved in a mission to protect a rare magical creature from some villains who want to use it for evil purposes.
I think Harry Potter and Snow White would be an interesting combination. Harry is used to fighting dark magic and Snow White has her own charm and innocence. Harry could protect Snow White from the Evil Queen using his magic skills, and Snow White could teach Harry about the power of hope and kindness in a more fairy - tale - like way.
I think Harry Potter and Cloud Strife would be an interesting pairing. Harry is a young wizard with a strong sense of justice, and Cloud is a brooding and powerful warrior. They could learn from each other's strengths. Harry could show Cloud the power of magic, and Cloud could teach Harry about combat skills and determination.
I think Harry and Steven would be the most interesting. Harry has his own burdens of being the 'Chosen One' in the wizarding world, and Steven has to deal with his role as a half - Gem. They could understand each other's struggles and learn from each other's ways of handling difficult situations.
I think Harry Potter and Tohru Honda would be an interesting combination. Harry has been through so much trauma and has a strong sense of justice. Tohru, on the other hand, is kind - hearted and has a way of bringing out the best in people. Their meeting could lead to Harry learning more about emotional healing from Tohru, and Tohru getting to experience the wonder of magic.
Hermione and Sakura would be a great combination. Hermione is highly intelligent and book - smart, while Sakura is a skilled medical ninja with her own growth arc in terms of strength and confidence. They could exchange knowledge, with Hermione teaching Sakura about the complex magic theories and Sakura showing Hermione some of the medical ninjutsu. They could also work together to solve problems, using their combined wits and skills.
Another interesting combination could be Watson and Ron. Watson is a kind - hearted and practical man, while Ron is loyal and has his own brand of humor. They could form an unlikely friendship. Watson could introduce Ron to some Muggle things like medicine and technology, while Ron could show Watson the wonders of the wizarding world, like the magical creatures and the use of magic wands.
A really interesting combination would be Sirius Black and Naru from Ghost Hunt. Sirius has his wild side and his knowledge of the dark arts and the wizarding world. Naru is very mysterious and has great skills in ghost hunting. They could either be at odds or work really well together, depending on the situation. Their combined knowledge and personalities would make for a very engaging story.
Hermione Granger and Sherlock would be an interesting pair. Hermione is extremely intelligent and well - read in magic. Sherlock is a master of deduction. She could introduce him to the complex world of magic, and he could help her with his logical thinking when it comes to non - magical mysteries at Hogwarts. They could also have some really interesting debates about the nature of knowledge, whether it's through magic or pure logic.
Harry Potter and Altair would be a great combination. Harry's sense of justice and Altair's Assassin skills would make for an exciting duo. They could learn from each other, with Altair teaching Harry about stealth and combat techniques from the Assassin's Creed world, and Harry showing Altair the power of magic.
