Sephiroth's character would bring a new level of complexity to the Attack on Titan universe. His stoic nature and his drive for power could be contrasted with the more desperate and survival - based motives of the AoT characters. He could introduce new fighting techniques and strategies, and his very existence could force the people in the walls to reevaluate their understanding of the world outside. For example, his knowledge of magic or otherworldly forces could make them question what else is out there beyond the Titans.
Sephiroth would be a very powerful and somewhat out - of - place character. His long silver hair and his calm, menacing demeanor would make him stand out. He'd likely be seen as a mysterious figure. His combat abilities would make him a valuable asset in the fight against Titans, but his motives might be questioned as he's not from that world.
Batman would be a great addition to the Attack on Titan story. He could use his martial arts skills to take on Titans up close. His Batarangs could be modified to be more effective against Titans, like having explosive tips. He'd also be able to analyze the situation quickly and come up with strategies, which is something the characters in Attack on Titan often struggle with.
Well, Naruto's godlike abilities would likely change the power dynamic. He could easily take on Titans single - handedly. For instance, his ability to transform into the Nine - Tails form would make him a giant - sized threat to the Titans. His chakra could also be used to heal the injured in the Attack on Titan world, which is something they desperately need.
Well, it could be about Sephiroth using his incredible combat skills from Final Fantasy in the world of Attack on Titan. Maybe he teams up with the Survey Corps to take on the Titans. He might use his Masamune sword to slice through the Titans' nape with ease, bringing a new level of badassery to the fight against the Titans.
Sakura Haruno would likely develop her combat skills further. In the Attack on Titan world, she'd face different types of enemies compared to Naruto. So, she'd adapt her fighting style. For example, she might learn to use the 3D Maneuver Gear more effectively, combining it with her quick punches and kicks. Her medical skills would also be crucial for her development. She'd be constantly saving lives, which would give her a sense of purpose and boost her confidence.
The world of Attack on Titan would experience a major transformation with the introduction of Pokemon. Socially, the relationship between people would change as they bond over their Pokemon. There could be Pokemon centers and Pokemarts within the walls. Economically, a new industry would emerge around Pokemon. In terms of combat, as I mentioned before, different types of Pokemon would bring new tactics. Fire - type Pokemon could set the Titans on fire, ice - type Pokemon could freeze them, and so on. Also, the idea of Pokemon evolution could be incorporated into the story. Maybe the more a trainer and their Pokemon fight Titans together, the stronger their bond and the more evolved their Pokemon becomes, making them even more effective against the Titans.
Kaneki Ken could fit in as an outsider with a dark past, much like some RWBY characters. His struggle with his dual nature as a human - ghoul could parallel the internal conflicts of RWBY characters dealing with their own powers and identities. For example, Ruby's journey to understand her silver - eyed warrior powers.
Sasuke's sharingan would give him a huge advantage. He could predict the movements of the Titans, much like he does with his opponents in the Naruto world. His ninjutsu skills, such as fire - style jutsu, could be used to fend off Titans. For example, he could use his fire - style to blind a Titan or create a barrier of fire to keep them at bay. Also, his speed and agility from being a ninja would make him a very effective fighter against the Titans. He could quickly move around the battlefield, avoiding the Titans' attacks and finding their weak points.
In a Juubi Naruto Attack on Titan fanfiction, Naruto could form an alliance with Eren. Naruto's ability to sense danger and his superhuman strength would be a great asset. He could teach Eren some of his ninja techniques, like how to better control his Titan form. Maybe Naruto could even find a way to use his Sage Mode to understand the Titans better.
Padme's strong sense of justice would make her a natural ally in the fight against the Dark Arts. She would be appalled by Voldemort's actions and would likely join the Order of the Phoenix. Her courage would also shine through, whether it's facing Death Eaters or standing up to the more bigoted wizards in the Ministry of Magic.
Naruto's powers would need to be adjusted to fit the AoT setting. His chakra - based attacks could be seen as a new form of energy in that world. His ability to run on walls like a ninja could be similar to the ODM gear users, but with his own unique style. Maybe his summoning jutsu could bring in some helpful creatures to fight the Titans.
