In fanfiction, the possibilities are nearly endless. Regarding Edward Elric becoming a homunculus, it could be a very interesting concept. If he were to become one, it would completely change his relationship with other characters. For example, his brother Alphonse might react in a very different way. Also, Edward's own view of himself and his abilities would be transformed. His struggle with his new form, if it were to happen, could be a central theme in the fanfiction. Maybe he would try to find a way to reverse the process, or perhaps he would embrace his new existence as a homunculus. It all depends on the creativity of the fanfiction author.
One possible plot for 'naruto is a homunculus fanfiction' is that Naruto is secretly a homunculus created for a specific purpose, say, to be a weapon in a long - forgotten war. As he grows up, he starts to show signs of his homunculus nature, like enhanced physical abilities or strange powers that are not part of normal ninja training. He then has to figure out who made him and why, while also dealing with the fact that some in the ninja world might see him as an abomination. Along the way, he could meet other homunculus - like beings or discover ancient secrets about the connection between homunculus creation and the ninja arts.
There's a fanfiction where the concept of homunculus is intertwined with the Naruto lore in a really interesting way. It delves into the idea of pride within the characters, both the Naruto characters and the homunculus. It shows how their different concepts of pride can lead to conflicts or alliances. In this fanfiction, the homunculus might have abilities that are foreign to the Naruto world, and the Naruto characters have to adapt to deal with them. It also examines how the pride of the homunculus, which could be different from human pride, affects their actions and decisions.
Often, there could be a plotline about how his relationships change. For instance, his friends might be distrustful or scared of him at first. And he has to work hard to prove that he is still the same Edward on the inside. Another plotline might involve him having new and strange powers as a homunculus, and he has to learn to control them. Maybe he uses these powers to fight against other homunculi who are causing trouble in the world of the fanfiction.
Well, in this concept, it combines the world of Naruto with the idea of homunculus. Homunculus are often artificial beings in other fictional concepts. In the fanfiction, they are likely inserted into the Naruto universe. The 'pride' aspect could be related to the homunculus having a sense of superiority due to their special creation or abilities.
Sasuke might be intrigued and also a bit jealous of Naruto's homunculus powers. He'd probably see it as another thing that makes Naruto different and stronger. Sakura would likely be worried at first, but then try to understand and help Naruto control his new - found abilities.
