Having Tenseiga could really shake things up for Inuyasha in fanfiction. It might alter his relationships with other characters and create unexpected storylines and challenges.
It could lead to some major changes in the story. Maybe Inuyasha would be even more powerful and have an easier time defeating his enemies.
In fanfiction, the baby could be the key to unlocking some long - lost secrets in the Inuyasha universe. Since Sesshomaru and Inuyasha have such complex histories and lineages, the baby might hold the answers to ancient prophecies. It could also have a special bond with the Jewel of Four Souls, perhaps having a unique way of controlling or protecting it that neither of its parents had. And of course, there would be all kinds of emotional drama as the two brothers - turned - co - parents deal with their new relationship.
Well, if Inuyasha was a girl, the dynamics of her interactions with other characters would likely change. Her motivations and actions might be driven by different emotions and perspectives.
Well, his tail in fanfiction could be a sign of vulnerability too. Writers might use it as a way to show his softer side. For example, if someone were to grab his tail, it could make him feel really uncomfortable or even weak. It could also be a way for him to show affection in a non - human way, like wagging it when he's happy around Kagome.
One possible type of fanfiction could involve Inuyasha being verbally abused by some of the villagers who fear his half - demon nature. They might hurl insults at him, making him feel isolated and angry.
The Naraku would be a likely kidnapper. He is always plotting against Inuyasha and trying to get his hands on the Tessaiga. Kidnapping Inuyasha would be a way for him to either steal the sword or find a way to break Inuyasha's spirit so that he can no longer oppose him.
The theme of redemption can also be explored. Suppose a villain from Naruto's world ends up in Inuyasha's world. The different environment and the values of the people there might make them question their actions and seek redemption. It's an interesting way to give depth to otherwise one - dimensional characters.
Another reason might be revenge. There could be a character who has a grudge against Inuyasha or someone close to him. So, they kidnap him to make him suffer or to use him as bait to draw out his friends. For example, if there was a demon whose family was slain by Inuyasha in the past, they might kidnap him for revenge.
Sesshomaru would raise the baby with a combination of discipline and protection. He would protect the baby from any threats, using his powerful abilities. At the same time, he would discipline the baby when it made mistakes, teaching it the ways of the demon world. Inuyasha, on the other hand, would add a more carefree and emotional touch to the parenting, creating a balance in the baby's upbringing.
One common scenario is when Koga gives Kagome a gift. Inuyasha will feel jealous and might try to find a better gift for Kagome. Another scenario is when Koga saves Kagome from danger. Inuyasha will be jealous that Koga got to be the hero instead of him. He'll then vow to protect Kagome better in the future.
They would probably have a complex relationship. They might start off not knowing about their relation and then have a big revelation. At first, they could be rivals, given their strong personalities.
