Naruto could use his Rasengan to create a big enough explosion to scatter the mob and then make his escape. He might also use his speed to quickly dash through the crowd and find a hiding place.
Well, if Naruto is attacked by a mob in fanfiction, it could lead to some interesting character development. He could use this situation to understand the common people's fear or misunderstanding of him better. Maybe he'd try to talk to them in the middle of the fight, like he did with Pain, to make them see his point of view. And depending on the nature of the mob, he could also discover new threats or allies within the group.
In fanfiction, Naruto has a lot of ways to escape from Akatsuki if kidnapped. He could wait for an opportunity when the Akatsuki members are preoccupied with their internal disputes. Since he has a strong bond with his friends in Konoha, they might be on their way to rescue him. Naruto could also use his unique Uzumaki bloodline abilities, like his strong life force, to endure any torture or imprisonment until he finds a way to get out. He might even discover some secrets about the Akatsuki during his captivity that could be used to his advantage.
He could use his Rasengan. If he manages to gather enough chakra secretly, he can surprise his captors with a powerful Rasengan and break free.
He could use his ninja skills to fight back. Naruto has a wide range of jutsu at his disposal, like the Rasengan. So, he might quickly launch a counter - attack to protect himself.
Naruto could try to befriend some of the Kumo ninjas who might not be in favor of the kidnapping. By winning them over, they could help him escape. Also, he could use his knowledge of ninja techniques and his quick thinking. For example, he could use substitution jutsu to switch places with an object when the guards are not looking and then make a run for it.
Naruto could use his ingenuity and ninja skills to escape. Maybe he'd find a way to hack into the system using his chakra in a unique way. Since he's used to finding solutions in tough situations in his own world, he might discover a hidden loophole in the SAO system.
Naruto could use his shadow clones to create distractions. He could make a large number of clones and while the Akatsuki members are dealing with the clones, he could find an opening to escape. Also, he might be able to tap into the power of the Nine - Tails more than ever before in a desperate situation, using its strength to break free from any restraints.
Well, she might be rescued by her friends. In many fanfictions, her Shadowhunter comrades would come to her aid, using their unique skills to fend off the attackers.
Well, in this fanfiction, Deeks might face a physical attack from an unknown assailant. Maybe it's someone from his past, like an old enemy he made during one of his cases. He could get injured badly and have to rely on his friends and colleagues to help him out.
I recommend the book Immortal Evil God. The protagonist of the novel refined himself into a super defensive magical equipment, which was unprecedented. Under many difficult circumstances, he successfully broke free from the chains and led the people of Black Prison to wander the world. This novel had many special plots such as martial arts, as well as many exciting scenes. I hope you like my recommendation. Muah ~
