In some fanfictions, Naruto saves Kakashi from the brink of death. For instance, Kakashi could be poisoned by a rare and deadly toxin. Naruto, with his determination, goes on a quest to find the antidote. He overcomes many obstacles, battles different creatures, and finally retrieves the antidote to save Kakashi. This showcases Naruto's loyalty and his growth as a shinobi.
In some fanfictions, Naruto saves Obito by first understanding the root of Obito's pain. Obito was driven to his actions because of the loss of Rin and his disillusionment with the ninja world. Naruto, having experienced his own share of losses, is able to empathize. He then uses his positive influence and unwavering belief in the goodness of people. For instance, he might show Obito the new, more united ninja world that he has been working towards. This gives Obito hope and makes him realize that there is still a chance for a better future, and thus he is saved.
In some fanfictions, Sakura is trapped in a genjutsu created by a rogue ninja. Naruto, with his strong willpower and ability to break genjutsu, manages to enter the illusory world and free her. There are also those where Sakura is in danger during a war, and Naruto, as the hero, uses his Nine - Tails chakra to shield her from harm and then defeats the opposing forces.
One great example could be a fanfiction where Naruto has to battle a powerful new enemy who has kidnapped Gaara. Naruto uses his new jutsu and his unwavering friendship to break through the enemy's defenses and save Gaara. Another might be a story set in an alternate universe where the circumstances of Gaara's capture are different, but Naruto still goes to great lengths, even sacrificing his own safety, to rescue Gaara.
One great example could be a fanfiction where Snape overcomes his long - held grudges against Sirius in a life - or - death situation. Maybe Sirius is framed again, and Snape, having discovered the truth through his own investigations, steps in to save him. This could involve a complex plot where Snape has to fight against his own pride and the expectations of others in the wizarding world.
One great example could be a story where James discovers a plot against Snape that no one else is aware of. He then uses his skills and Gryffindor courage to protect Snape from the impending danger. This could involve him facing off against some dark wizards who have a vendetta against Snape.
There could be a fanfic where Elena is in danger from a group of werewolves. Klaus, having his own reasons for not wanting Elena to die, steps in. He uses his cunning and strength to fend off the werewolves. This could lead to a change in their relationship, with Elena starting to see Klaus in a different light, perhaps as more than just an enemy.
One example could be a fanfiction where Naruto is wrongly accused of something in the village, and Kakashi steps in to defend him using his wisdom and influence. Another might be a situation where Naruto is facing an external threat and Kakashi defends him on the battlefield, which is then detailed in the fanfiction.
In such a fanfiction, perhaps Kakashi might save Iruka from a dangerous enemy like Orochimaru's minions. Kakashi, with his Sharingan and powerful jutsu, could arrive just in time to fend off the attackers.
One great example is a fanfic that delves into Kakashi's time in Anbu and his complex relationships with his comrades. It might show his internal struggles with the darker aspects of the Anbu missions.
Well, it could be that in the fanfic, Kakashi saves Naruto from a trap set by Orochimaru. Kakashi arrives just in time, using his lightning - style jutsu to break through Orochimaru's defenses and snatch Naruto away from the clutches of danger. This would create a tense and exciting moment in the story.
