Tsukune's moral compass might shift. Ghouls in many stories have a more amoral approach to survival. Tsukune would have to fight against this natural inclination of his new form. He might start to question the values he once held dear and have to re - evaluate his place in the world of Rosario Vampire, trying to find a way to be a 'good' ghoul in a world full of different and often conflicting species.
In a Rosario Vampire Tsukune Ghoul fanfiction, Tsukune might face new challenges. He could be hunted by anti - ghoul organizations because they mistake him for a ghoul due to some new power he has acquired. This would force him to prove his innocence and also learn more about the world of ghouls in the process.
Rosario Vampire and Tokyo Ghoul are both very popular in the anime and manga world. A fanfiction combining Tsukune from Rosario Vampire with elements of ghouls could be really interesting. It might explore how Tsukune, who is already in a world full of vampires, werewolves and other supernatural beings, would interact with ghouls. Maybe he would form an alliance with some ghouls against a common enemy in the Rosario Vampire world.
Perhaps Tsukune, as a ghoul, starts to have a different view of the other supernatural beings at the academy. He could be drawn to the darker aspects of the ghoul world, which might put him at odds with the more light - hearted or morally upright characters. For example, he may have conflicts with the school's authorities who are trying to keep the peace between different species.
His character could develop in a way that he becomes more confident in his abilities. As a vampire, he has new powers at his disposal. He might use these powers to protect those he cares about more assertively. However, he also has to control his new instincts, which could lead to internal struggles. For example, he might be tempted to use his vampire charm to manipulate situations, but then feel guilty about it later.
Moka would be devastated. She has a strong bond with Tsukune, and his death would likely send her into a deep state of grief and anger. She might go on a rampage seeking revenge against whoever or whatever caused his death.
First, know the characters well. Tsukune is a complex character with his own growth arc. Make sure to stay true to his personality. Also, understand the world of Rosario Vampire, like the different monster species and their cultures. Then, come up with an interesting plot. It could be a new adventure for Tsukune or a different take on his relationships.
Tsukune and Ruby's relationship could develop further through shared experiences. For example, if they both participate in a school event like a yokai - human cultural exchange. This would force them to work together and understand each other's cultures better, deepening their connection.
It could be really exciting. Tsukune with Saiyan powers would be super strong. He might have the ability to transform and his battles would be intense. Maybe he would use his Saiyan strength to protect his friends in the Rosario Vampire world from new and powerful enemies.
Tsukune could fit in as an outsider with unique abilities. His vampire powers would be a contrast to the ice - based powers in the Sub Zero world. He might be initially seen as a threat or a curiosity.
Tsukune's vampire form in fanfiction can vary greatly. Some authors might focus on the emotional aspect of him dealing with this new side of himself. He could struggle with the urge to feed on blood, or he might embrace it as a part of his new identity. Additionally, his relationships with other characters, especially Moka, can be significantly affected by his vampire form.
