His hair might become unkempt. Instead of the spiky, energetic look, it could be long and messy, falling over his face as a sign of his new withdrawn state. He may also stop wearing his bright orange jumpsuit and opt for darker colors like black or dark blue.
He could have dark circles under his eyes from all the sleepless nights of brooding. His eyes themselves might lose their usual sparkle and become dull. He may also start wearing some kind of necklace or bracelet that has a sad significance, like a memento of a lost friend.
Yes, it can. Piercings can add an edgy or unique look to Naruto in fanfiction. It might make him seem more rebellious or cool, different from his original appearance in the official series.
Well, Naruto has his own unique style, so dressing like Tobirama would make him look more solemn. Tobirama's style is more traditional and reserved. Naruto might look less of his boisterous self with Tobirama - like robes and maybe a different hair - style to match. His bright orange jumpsuit would be replaced by something more in line with Tobirama's era, like dark - colored robes perhaps. It would be a big change from his usual look.
Typically, he might gain some Hollow - like features. His eyes could change, perhaps becoming more like a Hollow's with a yellowish glow or a different shape. His hair might also take on a wilder look, almost as if it has a life of its own, similar to how a Hollow's reiatsu can make their hair seem to move unnaturally.
Well, his whiskers are quite a distinctive feature. Without them, he might look more like a normal boy at first glance. His face would seem less foxy, and perhaps a bit more plain. It could also make his expressions seem less unique as the whiskers often added a certain charm and playfulness to his look.
Naruto's skin might start to glow with a strange energy, similar to how Kaguya seemed to have an otherworldly aura. His eyes could change color to something more like Kaguya's, perhaps a deeper, more mysterious hue. And his clothing might even transform to be more in line with Kaguya's style, as if the absorption of her power also influenced his physical form in that way. He might also grow taller or more muscular as a result of the new power coursing through his body.
In fanfiction, the naruto kyuubi suit can change his appearance quite a bit. His hair could become more wild and take on a reddish tint, like it's being influenced by the Kyuubi's chakra. His eyes might glow a different color, perhaps a deep red. Also, the suit itself could be form - fitting and have a pattern that resembles the Kyuubi's fur. This makes Naruto look more intimidating and shows his connection to the powerful nine - tailed fox.
Often, Naruto's appearance may change to incorporate some of Kurama's features. He might have red - tinged hair or his eyes could take on a more fox - like appearance, like slitted pupils or a red glow.
His relationship might become strained at first. His old friends in Konoha might be confused or even angry about his banishment. But some, like Shikamaru or Sakura, might secretly hope for his return and keep in touch with him in secret ways.
His friends might be initially shocked. Sakura could tease him about it at first but then grow to like the new look. Sasuke might be indifferent on the surface but secretly find it interesting. His enemies might underestimate him, thinking he's become more of a softie with the long hair, but then be surprised by his unchanged combat skills.
Well, it might make him look more fearsome. With the Kyuubi motifs on the unitard, his overall presence could be more intimidating. Maybe the unitard has a red color scheme like the Kyuubi's chakra, and it makes his eyes seem to glow more intensely.
