What could be the possible reasons for Naruto getting sick as an infant in fanfiction?

One reason could be that he was exposed to some kind of harmful chakra or energy in the village. Maybe some leftover dark jutsu residue affected his weak baby body.

Maybe Naruto has seen too many unrealistic or out - of - character portrayals of Konoha in the fanfiction. For example, some might make Konoha overly cruel or its people too stupid, which goes against his understanding and love for his village.

In fanfiction, Katniss might get sick due to exposure to new and dangerous toxins in the post - Hunger Games world. Maybe she's exploring uncharted areas and breathes in something harmful.

Well, in some fanfictions, it could be because of a curse or a jinx that was unknowingly placed on him before he arrived at the Burrow. The Burrow is not always a completely safe place, and with all the comings and goings of wizards and witches, someone with ill intentions could have targeted Harry. Also, he might have eaten something that didn't agree with him. The Weasley family's cooking, while delicious most of the time, could have used some ingredients that Harry's body wasn't used to.

One possible reason could be that he breaks some important rules within the fan - created world. For example, if the fanfiction has a strict code of honor and Naruto is made to cheat in a crucial competition, that could lead to his disqualification. Another reason might be that he is framed by an antagonist. The antagonist could plant false evidence against Naruto, making it seem like he has violated the rules, thus getting him disqualified.

Maybe he's tired of the same old dynamics. In fanfiction, sometimes the relationships in Team 7 can be written in a very repetitive way. For example, Sasuke's brooding and Sakura's one - sided love for Sasuke can become overdone, making Naruto feel sick of it all. Also, if the fanfiction focuses too much on the team's conflicts without any real development, it could be a reason.

Maybe Naruto is sick of Sakura in fanfiction because her character is often portrayed as too pushy or one - dimensional. In some fanfictions, Sakura might be overly obsessed with Sasuke and Naruto just gets tired of her constantly going on about it.

Well, in the fanfiction, perhaps Naruto realizes that Konoha's politics are too complex. There are always hidden agendas and power plays. He, being a straightforward person, might get tired of all the behind - the - scenes stuff. Also, he may feel that his friends are changing because of Konoha's influence. For example, they might be more focused on the village's reputation rather than their true feelings, which makes Naruto sick of it all.

In fanfiction, Naruto could feel sick due to overusing his chakra. He often pushes himself to the limit in battles and training, and this excessive chakra use might take a toll on his body, making him feel ill.

Perhaps in the fanfiction, Tobirama's sickness makes him weak and he starts to reflect on his life and the choices he has made. He could have conversations with his loved ones where he reveals his regrets or hopes. This introspective side of him due to the sickness could add depth to his character. Also, his sickness might be a catalyst for changes in the village he has helped build, as others step up in his absence.
