There could be a fanfiction where Naruto is under some sort of genjutsu (illusion). Gaara, being aware of Naruto's importance, might use his own unique chakra signature or some sand - based technique to disrupt the genjutsu and bring Naruto back to reality. This would require Gaara to have a deep understanding of both genjutsu and Naruto's situation, highlighting their bond in the fanfiction world.
Well, in many such fanfictions, Gaara might use his sand powers. He could sense Naruto is in danger through his connection to the sand or his own instincts. Then, he'd quickly move in, using his sand to shield Naruto from any attacks by the Akatsuki members, like blocking their jutsu with his powerful sand barriers.
He could use his sand powers to create a barrier between Naruto and Sakura.
In the fanfiction, Naruto might comfort Gaara by sharing his own experiences of being an outcast. He could tell Gaara about how he was shunned in the village at first because of the Nine - Tails inside him. Naruto would say that just like him, Gaara has the strength to rise above people's fear and hatred. He might put his hand on Gaara's shoulder and give him a reassuring look, saying that they are both jinchuriki and they can support each other.
One reason could be friendship. Gaara and Naruto have a special connection in the original story. In fanfiction, this connection could be deepened, and Gaara would save Naruto because he values their friendship. Just like Naruto once reached out to Gaara, Gaara would do the same for Naruto when he's in danger.
Well, in many fanfictions, it might start with Gaara noticing Naruto's unique strength and unwavering spirit. Naruto's ability to reach out to others, even his enemies, could be very appealing to Gaara. Maybe during a joint mission, they have to rely on each other, and Gaara starts to see Naruto in a different light, gradually developing deeper feelings as they spend more time together.
In some fanfictions, Gaara might use his past experiences and his once cold - hearted nature to make Naruto feel powerless. For example, if Gaara constantly flaunts his strength which he once used for destruction and Naruto feels he can't reach that level of power to protect his friends, it could lead to Naruto feeling depressed.
Once he realizes that Gaara is serious about the kidnapping, Naruto would start to plan his escape. He would use his ninja skills and his quick thinking. Naruto has a lot of experience in getting out of tough situations. He would look for any weaknesses in Gaara's defenses or in the place where he is being held. And while he's planning his escape, he would still be trying to reason with Gaara, hoping to resolve the situation without having to fight his friend.
In this fanfiction, Gaara's possessiveness could be demonstrated in different ways. Firstly, he might be possessive in terms of her time. He wants to spend as much time as possible with her. Secondly, he could be possessive about her emotions. He doesn't want her to be too friendly with other guys as he fears she might develop feelings for them. Also, he may be possessive about her safety, always being on guard and ready to fight off any threats to her.
In some fanfictions, Jiraiya might save Naruto by teaching him powerful new jutsus. For example, he could pass on some secret toad - related techniques that Naruto uses to defeat a powerful enemy.
In some Naruto fanfictions, Houndoom might save Naruto by using its powerful fire - based attacks to fend off enemies. For example, if Naruto is surrounded by a group of rogue ninjas, Houndoom could blast them with its Flamethrower move, creating a wall of fire that the enemies can't cross, thus buying Naruto time to escape or come up with a counter - attack strategy.
