One great 'Naruto Escape' fanfiction is 'Naruto's Great Escape'. It focuses on Naruto finding unique ways to break free from difficult situations. The story really plays on Naruto's character strengths and his determination to not be held back.
Yes, in many Naruto fanfictions, Orochimaru does escape various situations. Fanfic authors often play around with the idea of Orochimaru's cunning nature allowing him to slip away from his pursuers, whether it's from Konoha ninjas or other threats. This can add an interesting twist to the story as his escape can lead to new plot developments.
Another way is that he forms an unexpected alliance within Iwa. There could be a dissident group in Iwa who oppose the capture of Naruto. They might help him escape in exchange for some future favor or because they believe in Naruto's cause. Naruto has a way of inspiring people, even those who are initially his enemies, so this is a plausible scenario.
Well, Naruto might be able to escape by using his strong will and his ability to make friends. He could try to talk to Pein, find some common ground, and convince him to let him go. If that doesn't work, he could use his Rasengan in a creative way. For example, he could use it to create a hole in the wall or floor of the place where he is being held. He could also call on his friends, like Kakashi or Sakura, to come and rescue him. They might be able to use their own skills to get past Pein and free Naruto.
Perhaps Naruto realizes that forcing Sasuke to stay would only create more resentment. By letting him escape, he hopes that Sasuke will have time to think and eventually return willingly. In the fanfiction, it could also be that Naruto has some sort of premonition that Sasuke's escape is necessary for a greater good in the future, like saving the village or the ninja world in a different way than if he were held back.
Naruto could use her shadow clone jutsu. She could create multiple clones while Sasuke is distracted and then make her escape. Since she has a large amount of chakra, she can afford to create a lot of clones to confuse Sasuke.
Naruto could use his shadow clones. He might create a bunch of clones to distract Madara while he finds a way to break free from whatever is binding him. Since Madara is a powerful opponent, Naruto would need to be very strategic with his clone usage.
Well, Naruto might escape by using his wits. He could pretend to be compliant with Orochimaru's plans at first, gain Orochimaru's trust a little bit, and then when Orochimaru least expects it, he could make his move. He could also find an ally within Orochimaru's lair. Maybe there's a henchman who has a change of heart and helps Naruto escape. Or, Naruto could discover a weakness in Orochimaru's security system or jutsu that he can exploit to get away.
Another way Naruto could escape is by making an unexpected alliance. There might be other characters in the fanfiction who are also against Obito. Naruto could convince them to help him. For example, if there are some anti - Obito ninjas in the area, Naruto could appeal to their sense of justice and work together with them to escape.
Naruto could use his shadow clones to create a diversion. He might make a bunch of clones and have them attack the Akatsuki members in different directions while he tries to find a way out. For example, he could use the chaos to search for a hidden passage or a weak spot in their hideout.
