Well, if they switched roles, Gaara might be the one with the Nine - Tails inside him. He'd have to deal with the villagers' fear and hatred in Konoha. Naruto, on the other hand, would be the Kazekage in Suna. He'd face different political and environmental challenges. For example, Naruto would have to manage the water resources issue in Suna which is quite different from what he's used to in Konoha.
Sakura's relationship with the new 'Naruto' (Gaara) would be very different. She might be more cautious around him at first due to Gaara's past reputation. For Kakashi, he'd have to approach mentoring Gaara - as - Naruto in a different way. In Suna, Temari and Kankuro would have to get used to Naruto as their leader. They might be initially skeptical but Naruto's charisma would likely win them over.
If Naruto and Kakashi switched roles, it would be quite interesting. Naruto would be the experienced and calm sensei. He might teach his students with his unique brand of enthusiasm and his own lessons learned from his journey. For example, he could teach them about never giving up in a more structured way like Kakashi does with his training. The village might see a more energetic and passionate leadership from him in guiding the new generation of ninjas.
If Naruto and Sasuke swapped roles in fanfiction, it would change the entire power balance and their relationships with other characters. The plot could take unexpected turns and offer a fresh perspective on the Naruto universe.
A 'Naruto and Gaara Roles Reversed' fanfiction could start with Gaara being the one full of energy and constantly getting into trouble in the Leaf Village. He'd be eager to prove himself, much like how Naruto was in the original. Naruto from Suna would have to deal with the harsh treatment from his own village due to being the Jinchuriki. Their first encounter would be really interesting, as their personalities and circumstances are flipped.
The relationship between Sasuke and Naruto (now from Suna) would be different. Sasuke might view Naruto as more of a threat due to his Jinchuriki status. Gaara, in the Leaf Village, would probably be more friendly towards Sasuke, trying to be his friend. Also, the relationship between Naruto and Sakura would be altered. Since Naruto is from Suna, Sakura might be more hesitant or even fearful of him at first.
Naruto could be a front - line fighter. His combat skills and powerful jutsus would be great for taking on tough enemies directly. He'd be the one charging into battle without hesitation. Gaara, with his sand powers, could be a great defender. He could protect the guild hall or his comrades during battles. His sand can form barriers and attack enemies at the same time.
In a 'rwby switched roles fanfic', a great plot could involve Ruby as Yang. She'd be the strong, brash fighter, not afraid to jump into a fight headfirst. Yang, in Ruby's role, would be the innocent - looking but actually very powerful fighter. She'd use her charm to fool opponents into underestimating her. Weiss and Blake could also switch, with Weiss being the more shadowy, cat - like character and Blake as the haughty, aristocratic type.
Perhaps the story could start with Fem Naruto coming to the Sand Village under some special circumstances and falling in love with someone there, resulting in Gaara's birth. As a mother, she would be protective of Gaara, especially considering his status as a Jinchuriki. She would train him not just in combat but also in emotional intelligence. Gaara would inherit some of her spunk and determination, and this could lead to a completely different story arc for him in the Naruto universe. He might be more confident and less haunted by his past because of Fem Naruto's positive influence.
I think Ruby would be really interesting if she took on Weiss's role. Ruby is so used to being the free - spirited leader, but as Weiss, she'd have to deal with all the expectations and formalities that come with being an heiress. It would be a huge change for her character and would force her to grow in different ways.
Well, it would be really chaotic. Naruto in Sasuke's body might struggle with Sasuke's more brooding and reserved nature. He'd probably be eager to show his friends that he's still 'Naruto' inside. And Sasuke in Naruto's body would have to deal with Naruto's boisterous energy. He might find it annoying at first but could also learn from Naruto's positive attitude towards friendship.
