In many fanfictions, Naruto might use new jutsus or a deeper understanding of his own power. Maybe he taps into a more powerful form of the Nine - Tails' chakra and combines it with his Sage Mode in a unique way to overpower Pain.
One interesting Naruto scream fanfiction could be where Naruto lets out a powerful scream during a really intense battle against a new, super - strong enemy. His scream might be filled with his determination and the chakra he's mustering up.
In some fanfictions, Naruto's pain might manifest through his actions. For example, he could become withdrawn and isolate himself from his friends. This is because Naruto has always been a social person, so any deviation from his normal behavior could be a sign of his internal pain.
One possible cause could be his sense of failure. Naruto always wants to protect his friends and village, so if he fails in a mission or is unable to save someone, it can cause him great pain.
The Scream was a novel written by Lu Xun. It was about a small figure who was oppressed by society. In desperation, he let out a cry to attract the attention of society and finally obtained freedom and dignity. This novel was known as a classic of modern Chinese literature for its strong ideology and artistry.
His fighting style could become more aggressive. Without the fear of pain, he might be willing to use more extreme techniques that would otherwise be too dangerous because of the pain they cause to the user. He could push his body to the limit more often.
Konan could be really interesting. In some fanfictions, she might have a different backstory or motivation that affects the Naruto vs Pain fight. For example, she could be secretly trying to stop Pain from going too far in his destruction of the Leaf Village.
Jiraiya could be a great addition. Since he was Pain's teacher, his presence could add a lot of depth to the story. He could offer insights into Pain's past and also help Naruto understand Pain better.
We might expect a unique blend of the two elements. For instance, Naruto's scream could be used to power up Benihime in some way. This could be a new power - up method that the author invents for the story.
It could be a story where Naruto's scream has some sort of special effect on Benihime. Maybe his scream is so powerful that it activates a hidden ability of Benihime. For example, in a battle situation, Naruto's scream of determination causes Benihime to glow brighter and gain extra strength.
