Well, if we consider their growth throughout the series. Naruto has grown into a very powerful Hokage - level ninja. Hinata has also become stronger. Sasuke is no slouch either, but he might be a bit more on his own compared to Naruto who has a great support system with Hinata. Sakura is strong but not as powerful as Naruto or Sasuke in terms of combat abilities. So overall, Naruto and Hinata might come out on top in this fictional battle.
In a fanfiction scenario, it's really hard to say who would win between Gaara and Sasuke for Sakura. Gaara has his powerful sand control abilities. He can create huge sand constructs and has a very strong defense. On the other hand, Sasuke has his Sharingan which gives him enhanced perception and the ability to copy jutsus. Also, he has his own unique ninjutsu like the Chidori. If it's a battle just based on power, it could go either way. But if we consider their motives for Sakura, Sasuke might have an edge in terms of his past relationship with her, which could make him more determined to win this 'battle' in the fanfiction.
In some fanfictions, Hinata might win because of her gentle yet powerful fighting style. Her Byakugan gives her an edge in perception, allowing her to anticipate Sakura's moves. Also, Hinata's Gentle Fist techniques can be quite deadly when properly executed.
It's hard to say for sure. If the fanfiction focuses on Hinata's growth, she could potentially defeat Pain through her own skills and some unexpected twists. But Naruto is also likely to be a major factor, so it could be a combined effort of both of them that overcomes Pain.
In a battle in a fanfic, Sakura's medical knowledge could also be a factor. She might be able to use her knowledge of the human body to find weaknesses in Hinata's attacks. On the other hand, Hinata's family techniques are not to be underestimated. Her ability to use chakra in a precise way might give her an upper hand. So, it's really hard to say who would win as it all depends on the specific circumstances created by the fanfic writer.
It really depends on the context. If it's a physical fight based on brute strength, Naruto would likely have the upper hand. He has access to the Nine - Tails' chakra which gives him superhuman strength. But if it's a fight that involves strategy and medical ninjutsu, Sakura could potentially win. She's a very intelligent fighter and her medical skills could be used in a creative way to disable Naruto.
I think Sakura would win. She's shown time and time again that she can hold her own in a fight. She's trained with Tsunade and has some serious punch - power. Hinata is strong too, but Sakura has more of an aggressive fighting style that would probably overpower Hinata in a direct fight within the context of fanfiction.
One possible plot could be a friendly sparring match. Naruto and Hinata are one team, and Sasuke and Sakura are the other. They start off with basic jutsu and gradually escalate as they try to outdo each other. There could be some friendly banter between Naruto and Sasuke, and Hinata and Sakura could also have their moments of showing off their skills.
In my opinion, Sakura would win. Sakura has shown great strength and combat skills. She was trained by Tsunade, one of the Sannin. She has superhuman strength which can cause massive damage. Ino, on the other hand, is mainly a mind - control type ninja. If Sakura can resist Ino's mind - control jutsu, which she likely can with her training, she can easily overpower Ino in a physical fight.
In a Naruto vs Hinata fanfic fight, Naruto has a lot of raw power. He has the Nine - Tails' chakra and a vast array of powerful jutsu like the Rasengan. However, Hinata is no pushover. She has the Byakugan which gives her incredible vision and predictive abilities. If Hinata could get in close, her Gentle Fist techniques could disrupt Naruto's chakra flow. But Naruto's speed and strength might be too much for her. It really depends on the circumstances of the fight in the fanfic, like if Naruto holds back because of his feelings for Hinata or if Hinata has some new power - up.
It's hard to say. If Naruto and Sakura work really well together, they could win. But Sasuke is extremely powerful too.
