It could limit their growth as ninjas. Since they are afraid of explosions, they may shy away from battles or training scenarios that involve explosive elements. This would prevent them from learning how to deal with such threats effectively and thus hold them back in terms of becoming stronger ninjas. However, on the other hand, it could also drive them to find alternative ways to fight and protect themselves that don't involve facing explosions directly.
The fear of explosions in this fanfic can deeply shape their characters. Kiba and Isse may develop a sense of vulnerability. This could lead to changes in their relationships with other characters. Some may try to take advantage of their fear, while others may try to help them overcome it. Their fear may also lead them to be more empathetic towards those who have similar fears or have been affected by explosions in the Naruto world. Overall, it's a complex factor that can have multiple impacts on their personalities and actions.
Another way to depict the fear is through their internal thoughts. The author could write in the first - person perspective for each character at times. Naruto might think about how the explosions remind him of the destruction he saw during the Pain invasion and how he doesn't want to see that kind of destruction again. Kiba could be thinking about how his ninja skills might not be enough to protect himself and his dog from the explosions. Issei might be having flashbacks to a past experience where he was nearly killed by an explosion and how that fear has now resurfaced.
One possible reason could be that they had a past traumatic experience related to explosions. Maybe they witnessed an explosion that caused harm to their loved ones or themselves. Another reason might be that explosions in the 'Naruto' world are often associated with powerful and dangerous jutsus or attacks, and they are simply afraid of the destruction and chaos that explosions can bring.
This fanfic concept could also lead to new alliances. Characters who oppose the use of fear toxin might team up to stop Naruto, while others who believe in his cause might support him. It would create a lot of political and social unrest in the Naruto universe.
Naruto could use his explosive - natured jutsus like the Rasengan. If he was sparring with Kiba, a misdirected Rasengan could hit something explosive nearby and cause an explosion involving Kiba. For Issei, if they were in a battle together, Naruto's chakra - infused attacks might react with Issei's energy - based powers in an unexpected way and create an explosion.
Since I don't know the exact content of this fanfic, it's hard to say. But it could have new characters created by the author. Maybe there's a character who is the source of the earth grudge and is very menacing, causing fear in others.
It might show some characters who are usually confident in the original Naruto series as being more self - conscious due to the fear of being feared. For example, Naruto himself might be more cautious about using his powers in public.
It shakes up the whole universe. It changes Naruto from a hero to a potentially dangerous entity. This could lead to a power shift in the ninja world. Enemies might see this as an opportunity to cause chaos, while allies would be confused and scared.
The theme of Ciel's fear of the dark can add a lot of tension to the plot. It creates new obstacles for Ciel to face, making the story more interesting.
One possible plotline could be that they are in a village or a world where there is a sudden increase in the use of explosive jutsus or weapons. Naruto, Kiba and Issei have to face their fear as they are constantly under the threat of these explosions. Maybe they start off by trying to avoid areas where explosions are likely to occur. For example, they might stay away from battlefields or places where ninja experiments with explosive substances are taking place. As the story progresses, they could be forced into situations where they have to confront their fear directly, like when their friends or loved ones are in danger in an explosion - ridden area. This would be a great opportunity for character development as they learn to overcome their fear for the sake of others.
It can create misunderstandings. For instance, his friends might think he doesn't like them if he recoils from their touches. His romantic relationships could also be affected. If he's in love with someone in the fanfiction, his fear of touch would make it difficult for him to show physical affection, which is an important part of a romantic relationship.
