Female Sasuke might have enhanced stealth abilities. In some ninja cultures, female ninjas were known for their grace and ability to blend in, so she could use this to her advantage. Also, she might develop a more intuitive fighting style, relying on her instincts more. Since she's now a girl, her chakra control could potentially be more refined, as some fanfictions depict female characters having a different kind of connection to their chakra.
The fusion would probably have enhanced physical abilities. With Naruto's stamina and Sasuke's speed, they could move faster and fight longer. And in terms of ninjutsu, they could combine their elemental jutsus. Maybe create a new fire - wind jutsu from Naruto's wind and Sasuke's fire.
Sasuke's Sharingan would be a great asset. It could help him see in the dark, which would be useful in places like Moria. His ability to copy other people's fighting styles could also come in handy when facing different foes in Middle - earth. And his speed and agility would make him a formidable opponent in battles against orcs or other evil creatures.
Sasuke's Sharingan would be a very powerful ability in the RWBY world. He could use it to predict the movements of Grimm or enemies in combat, much like how it works in the Naruto universe. His fire - based jutsu like Fireball Jutsu could be a unique form of attack against the Grimm.
For Naruto, being trained by Madara could mean he learns how to counter Uchiha - specific techniques more effectively. His physical strength might also increase due to the intense training. Sasuke would be able to better harness his hatred and turn it into a more focused power source. Madara's teachings could expose them to ancient jutsu and knowledge that would give them an edge over their enemies. Their teamwork might also be affected, as they would both be influenced by Madara's way of thinking.
Sasuke's Sharingan would be a very unique ability in the Fairy Tail world. It could give him an edge in combat against wizards. For example, he could use it to predict their attacks and counter them quickly. His fire - style jutsu could be on par with some of the fire - based magic in Fairy Tail, like Natsu's Dragon Slayer magic. Sasuke could also use his ninja skills such as stealth and quick movement to surprise his opponents in this new world.
Naruto's Rasengan could be translated into a powerful, concentrated force attack in the Navy Seal setting. It could be something like a special grenade or a close - range combat move. Sasuke's Chidori might become an electrified stabbing weapon or a way to short - circuit enemy electronics. Their ninja speed and agility would also make them excellent at traversing difficult terrains during missions.
Sasuke's abilities would be both advanced and out of place. His Sharingan skills would be very powerful compared to most in the Sannin era. But he would lack some of the basic knowledge and skills that were common in that time. For example, he might not be as well - versed in some of the traditional ninjutsu styles.
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.
The Sharingan might also give Naruto the ability to enter people's minds, at least to some extent. In the Naruto universe, the Sharingan has been shown to have some mind - related abilities. Naruto could use this to communicate with his friends in a more direct way, or perhaps even to break through genjutsu more easily. And, if he can enter the minds of his enemies, he could gather valuable information about their plans and weaknesses.
