The impact on the plot could also be emotional. Aang being shot by lightning would be a huge shock to his friends. This could lead to moments of self - doubt among them. For instance, Katara might blame herself for not being able to protect Aang. Sokka might question their ability to continue their journey without a fully functional Avatar. These emotional upheavals could add depth to the characters and drive the plot in new directions as they struggle to overcome their internal and external challenges.
Well, one possibility is that Aang's friends could find a way to heal him. Maybe Katara would use her waterbending skills in a new and innovative way to reverse the damage caused by the lightning. Another idea is that Aang could enter a spiritual realm while in this injured state and gain new insights or powers that would help him when he recovers.
His refusal can also build tension. Other characters might not understand his stance, or they might be frustrated by it. This can create conflict within the story, both between Aang and his allies, and between Aang and his enemies who might not expect his mercy. For example, some of his friends might think that killing a particularly dangerous enemy is the only way to ensure safety, but Aang stands firm, causing a rift in their relationships. This adds an extra layer of drama to the plot.
In some fanfics, Aang might die in battle against a powerful enemy. He gives his all but is ultimately overpowered.
It broadens the community's reach. Having Romans as part of the readership means the fanfiction has a more diverse audience, which can encourage more writers to explore different cultural elements in their works.
He might start by observing. Aang is a curious person, so he'd likely watch how people live, how they interact with technology. He may also try to find other benders to learn about any new developments in bending. And he'd probably use his kind heart to make friends easily in this new future environment.
Aang could save the Airbenders in the fanfiction by first finding out the root of the threat they are facing. If it's a powerful enemy bent on destroying them, he may seek allies among the other benders, like the Earth Kingdom or the Water Tribes. He'd then use his airbending to scout the enemy's territory undetected. Once he has all the information, he could use his skills to either directly confront the enemy or find a way to neutralize the threat. For instance, if the enemy is using some sort of dark magic, Aang could use his pure Avatar energy to dispel it and free the captured Airbenders. And of course, he'd use his airbending to fly around and quickly transport the Airbenders to a secure location.
Aang might go into a deep state of depression. He has always been an emotional character, and having his heart broken by Katara, someone he loves deeply, could send him into a downward spiral. He might isolate himself from his friends and stop practicing his bending for a while.
Well, Aang being the Avatar has a deep connection with the elements. In this fanfiction, perhaps he enters the Avatar State and uses all his elemental powers in harmony. He could use waterbending to create moisture and cool the volcano, combined with his airbending to disperse the heat and gases.
Often, it starts with the shooting incident. Then, it may show the immediate aftermath, like Anakin being rushed to medical help or his comrades trying to protect him from further harm.
The plot could develop in a way that Naruto's shooting forces the other characters to reevaluate their relationships. For example, his friends might realize how much they depend on him and become more determined to protect him in the future. It could also lead to a search for the person who shot him, which might uncover a hidden conspiracy in the ninja world.
