Another powerful combination could be Scarlet Witch and Roy Mustang. Scarlet Witch's reality - warping powers and Roy Mustang's ability to control fire through alchemy. Together, they could create massive and unique attacks. The Scarlet Witch could manipulate the fabric of reality to enhance Roy's fire - based alchemy, making it even more destructive and unpredictable.
If you combined Edward Elric and Eren Yeager, they would probably be very powerful. Edward has his alchemy skills which can be used for various things like creating weapons or barriers, and Eren has the ability to transform into a Titan. Together, they could use alchemy within the Titan form, perhaps creating stronger structures or weapons directly on the Titan's body.
Some characters might feel flattered. If the fanfiction portrays them in a heroic and positive light, especially if it emphasizes their good qualities like Edward's determination or Alphonse's kindness, they might secretly feel a bit of pride and be flattered by the author's view of them.
Edward Elric would be a very interesting choice. His brash and determined personality would clash and also blend well with the Fairy Tail mages. He could learn about the different types of magic in Fairy Tail and might even try to find a way to combine his alchemy with magic. His search for the Philosopher's Stone could also take an interesting turn in the Fairy Tail universe.
Edward Elric is often very popular. His complex character, with his determination and the heavy burden he carries, makes him a great focus for fanfiction. Writers like to explore his emotions further, such as his guilt over his failed human transmutation attempt.
Roy Mustang is also very memorable. His cool and calculating demeanor, combined with his ambition to become the Führer and his unique fire - based alchemy, really makes him an interesting character. He has a complex personality with his own moral code and a lot of depth to his character.
I think Naruto and Alphonse Elric would make a really unique pairing. Naruto's ability to see the good in people and his constant pursuit of friendship could be a great influence on Alphonse, who has been through so much. On the other hand, Alphonse's calm and reflective nature could help Naruto think more deeply about his actions. Another interesting pair would be Sakura and Izumi Curtis. Sakura could learn a great deal from Izumi's tough - love approach to training and her strong alchemical skills. And Izumi could perhaps be inspired by Sakura's medical knowledge. And finally, Shikamaru and Scar would be an odd but interesting pair. Shikamaru's intelligence and Scar's complex view of the world could lead to some really thought - provoking discussions.
Itachi and Roy Mustang would be an interesting duo. Itachi, with his complex past and powerful abilities, and Roy Mustang, with his ambition and strategic mind. They could share their knowledge of different forms of combat and power manipulation. Itachi might be intrigued by Mustang's use of alchemy for combat, and Mustang could be interested in Itachi's Sharingan abilities and how they can be used in battle.
Alphonse Elric might also be a favorite. His kind heart and his unique situation of being in a suit of armor could be further explored with the addition of gamer elements. For instance, he could have some sort of in - game mechanic related to his armor's abilities.
