Obviously, Naruto would be one of the main characters since it's his mask in the fanfic. There might also be his friends like Sasuke and Sakura. They could be involved in the story in different ways, either helping Naruto understand the power of the mask or being affected by the changes it brings to Naruto.
There might be. Naruto fanfic is a vast genre where writers like to experiment. The Happy Mask Salesman has a rather strange and captivating persona. Some fanfic authors may see the potential in bringing him into the Naruto universe to create new plotlines, perhaps involving strange masks with unique powers in the world of ninjas.
It could be out of jealousy. Sasuke might see Naruto as always hiding his true emotions and having this perfect image that others admire. By breaking the mask, he wants to expose Naruto's flaws and make himself feel superior. Or perhaps it's a way for Sasuke to assert his dominance over Naruto, to show that he can break through Naruto's defenses.
Maybe it was Jiraiya. Jiraiya was a very important figure in Naruto's life. He could have given Naruto the mask as part of a training exercise. He might have thought that wearing a mask would force Naruto to rely more on his intelligence rather than his brute strength in certain situations.
One great fanfic could be 'The Mysterious Fox Mask'. It delves into the origin of the fox mask in Naruto's world. It might show how the mask was created and what powers it could potentially hold. It could also explore the relationship between Naruto and the mask, like if it has a spirit of its own that Naruto has to bond with.
The blend of two different universes. Naruto's world is full of ninjas, chakra, and unique characters. Majora's Mask has its own dark, time - based mystery. When combined in fanfic, it creates a whole new set of stories. For example, seeing Naruto face the challenges of the three - day cycle in Majora's Mask's Termina is really engaging.
I'm not sure about a specific fanfic just on Naruto's oxygen mask. But you could try looking on fanfiction.net or Archive of Our Own. They have a vast collection of Naruto fanfics, and you might be able to find one that involves an oxygen mask in some interesting plot.
Well, one interesting aspect could be the unique character interpretations. Maybe the mask in the fanfic represents a hidden identity or a new power for Naruto. It could also introduce new plot twists related to the mask, like it having some ancient or forbidden power.
It could be for a more personal reason. Maybe he's going through some internal struggle or self - doubt, and wearing a mask is a way for him to create a new persona, a stronger and more confident version of himself. It's like a shield that allows him to face challenges he might not be able to as the regular Naruto.
Well, in a 'naruto finds the mask fanfic', it could involve Naruto stumbling upon the mask during one of his adventures. It could be that the mask is a key element in a new mission he undertakes. For example, he might find out that the mask is part of a set of artifacts that, when combined, can unlock a great power or reveal a long - lost secret about the ninja world. It could also lead to new alliances or enemies as he tries to figure out what to do with the mask.
