Fanfiction.net is also a great place to find Inuyasha human form fanfiction. There are different categories and filters you can use to narrow down your search. Just be aware that the quality can vary, so you might need to read a few to find the really good ones.
There could be a fanfiction where Inuyasha in his human form has to protect a village from a new threat. Since he doesn't have his full demon powers, he has to rely more on his wits and the help of his human friends. This would show a different side of his character, more vulnerable and yet determined.
A good plot could involve Inuyasha turning human at unexpected times. This creates a lot of chaos as his friends are used to his demon form. For instance, they might be in the middle of a battle with a powerful demon, and suddenly Inuyasha turns human. His friends then have to protect him while also trying to figure out how to turn him back. It could also be interesting if his human form has some sort of hidden power or connection that they discover during this time.
Well, in fanfiction, Kurama's human form could be a really imposing figure. He might have long red hair, just like his fox form's fur color, and bright, piercing eyes. Maybe he'd be tall and muscular, with a sort of wild, untamed look about him, still carrying that powerful presence that he has as a tailed beast.
Give the Okami in human form a backstory that ties them to their original form. Maybe they were cursed to be in human form as a punishment or they chose to take human form to better understand humans. Their actions should also be influenced by their Okami nature. For instance, they might be more in tune with the phases of the moon and act differently depending on whether it's a full moon or a new moon. Their speech could also be a bit more formal or archaic, reflecting their otherworldly origin.
Kagome is an obvious choice. She has a strong bond with Inuyasha already, and when he turns human, their relationship could take on new dimensions. She might have to be more protective of him, or they could have different kinds of interactions. Miroku is also interesting. His wisdom and his own goals could play a role in helping Inuyasha deal with being human. He could offer advice on how to handle the new situation, or he might have some knowledge about the cause of Inuyasha's transformation.
These alliances can also be a source of character growth. A human character might start off being afraid of demons but through an alliance, learn to see them in a different light. Similarly, a demon might gain a new perspective on humans. In some fanfictions, the alliance might even lead to a change in the social structure of the Inuyasha universe, with humans and demons starting to co - exist more peacefully. This is often a long and difficult process as there are many prejudices on both sides to overcome.
Often in fanfictions, Kurama's human form and Naruto have a more complex relationship. They could argue at times, especially when Naruto wants to take risks that Kurama thinks are too dangerous. But at the same time, they also share some really tender moments. For instance, Kurama's human form might comfort Naruto when he's feeling down about his past or his struggles with the village. They would have a deep bond that goes beyond just being a jinchuriki and a tailed beast.
Writing a great Arceus human form fanfiction requires several elements. Firstly, you need to have a clear understanding of the Pokémon lore, especially related to Arceus. This knowledge will help you create a believable backstory for its human form. For the plot, consider adding mystery. For instance, Arceus in human form wakes up with no memories and a strange mark on its body, and it has to figure out what it means. When it comes to dialogue, make it realistic. If Arceus is interacting with a trainer, the conversation should reflect their different perspectives. Also, use vivid descriptions. Describe how Arceus looks in human form, its mannerisms, and how it moves in the human world.
There's a fanfiction called 'When Sonic Becomes Human'. In this story, Sonic's transformation into a human is caused by a magical accident. The story then follows his attempts to figure out how to reverse it while also having to deal with school and making new friends as a human. It's really interesting to see how the author portrays Sonic's character in a human body, and how his friends react to his new form.
