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.
A combination of Roy Mustang from Fullmetal Alchemist and Mikasa Ackerman from Attack on Titan could be quite powerful. Roy has his flame alchemy which is very destructive, and Mikasa is an extremely skilled fighter. In a battle, Roy could provide long - range support with his flames while Mikasa gets up close and personal with enemies. The combination of her combat skills and his alchemy would make them a formidable duo against any threat, whether it's Titans or the enemies from the Fullmetal Alchemist world.
Well, consider combining Alphonse Elric and Armin Arlert. Alphonse is a skilled alchemist, and Armin is known for his intelligence. Together, they could come up with some very clever strategies. Alphonse could use alchemy to create distractions or defenses, while Armin plans out the overall battle strategy. Their combined abilities would make them a force to be reckoned with. For example, they could use alchemy to create false landscapes to mislead enemies, while Armin figures out the best way to attack or escape depending on the situation.
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.
Well, in some fanfictions, you might see Edward Elric from Fullmetal Alchemist teaming up with Eren Yeager from Attack on Titan. They could combine their unique abilities. Edward's knowledge of alchemy and Eren's Titan - shifting power could be used to take on common enemies. For example, they might face a new threat that is a combination of the Homunculi from Fullmetal Alchemist and some new type of super - Titan in the Attack on Titan world. And the different character dynamics, like Edward's hot - headedness and Eren's determination, would make for an exciting story.
They have different themes and storylines. Fullmetal Alchemist focuses on alchemy and brotherhood, while Attack on Titan is about fighting giants for survival.
Sasuke could also be a very powerful contender. His Sharingan and Rinnegan give him a lot of combat advantages. If he had Titan abilities, he could use his ocular powers to control and enhance the Titan form. He might be able to see the weak points of his enemies even more clearly in a Titan form and use his lightning - based jutsu more effectively, combined with the brute strength of the Titan.
A fanfiction might focus on a romantic relationship between Greed and the OC. Given Greed's nature, it would be a complex relationship. The OC could be initially attracted to Greed's boldness and power, but then has to deal with his flaws. Greed, on the other hand, might find the OC's purity or uniqueness captivating, and they have to navigate through the dangerous world of alchemy and power struggles while also dealing with their growing feelings for each other.
Some characters might be quite shocked or amused if they could read fanfiction about their own story. For example, Edward Elric would probably be very indignant at some of the out - of - character portrayals of himself. He's a proud alchemist and seeing himself depicted in a way that doesn't match his self - image would surely make him fume.
If we consider strategy and intelligence along with power, Levi from Attack on Titan could be a top contender. His incredible combat skills and quick thinking could make him a force to be reckoned with even among the superpowered heroes. But then there are heroes like Eraserhead who can nullify quirks, which could be a huge advantage against some of the more dangerous Attack on Titan characters.
One great fanfiction could be about Izumi's backstory before she became an alchemist. It might explore her early training days and the challenges she faced. For example, a story could focus on how she overcame the difficulties of learning complex alchemical theories without proper guidance at first.
There are many fanfictions where Ed is portrayed as a girl. Fanfiction writers like to play with the existing characters in new ways. By making Ed a girl, they can introduce new themes and perspectives. For example, it could change how the story deals with gender roles in the world of Fullmetal Alchemist. Also, it can create new emotional arcs for the character, as a female Ed might face different challenges and experiences compared to the male version in the original story.
FMAB is closer to the manga. It follows the original storylines more accurately and has less deviations.
