Well, a typical theme is identity crisis. In Tokyo Ghoul OC Ripper fanfiction, the character might be constantly questioning who they are. Are they more human or more ghoul? This internal conflict is really interesting. And then there's the theme of power and its corrupting influence. As the OC Ripper gains more power, it could change them, make them more violent or detached. And of course, survival is a big theme. The OC Ripper has to find ways to survive in a world that's out to get them, whether it's from the CCG (Commission of Counter Ghoul) or other powerful ghouls.
One common theme is the struggle between the human and ghoul nature. The OC Ripper, being an original character in the Tokyo Ghoul universe, often has to deal with the duality of having human emotions and the blood - thirsty instincts of a ghoul. Another theme could be isolation. Since ghouls are hunted and feared, the OC Ripper might find themselves alone, not fully belonging to either the human or ghoul society. Also, themes of revenge can be present. Maybe the OC Ripper has a past filled with pain caused by humans or other ghouls and is seeking vengeance.
Some common themes are the exploration of morality. The OC Ripper may have to make difficult choices that challenge the traditional concepts of right and wrong. For example, killing a human to survive. Another theme is friendship and loyalty. Despite being a ghoul, the OC Ripper might form deep bonds with other characters, either ghouls or humans who are more accepting. And the theme of adaptation is also there. The OC Ripper has to adapt to the ever - changing world of Tokyo Ghoul, new threats emerging, and new ways of living among humans and ghouls.
First, give the OC Ripper a unique backstory. Maybe they were a human who was turned into a ghoul in a very unusual way. Second, define their personality traits clearly. Are they more of a loner or do they seek companionship? Third, give them a distinct appearance. It could be something that sets them apart from other ghouls in the Tokyo Ghoul world, like a special kagune shape or color.
One common theme is the struggle for identity. OCs often have to figure out where they stand in the world of ghouls and humans. For example, they might be half - ghoul and have to decide which side to embrace.
One plot idea could be your OC being a new ghoul trying to find their place in the ghoul society. They might start at the bottom, having to learn the rules of the different ghoul groups and facing discrimination from more established ghouls. Another idea is that your OC discovers a secret about their transformation that no one else knows, like it was part of a secret experiment by the CCG. They then have to figure out what to do with this knowledge while also avoiding being caught by the CCG.
One common theme is the battle between good and evil within Stefan. The OC is usually involved in this internal struggle. Also, there's the theme of self - discovery. Stefan, through his interactions with the OC, discovers new aspects of himself. For example, he might find that he has more capacity for love or control than he thought. And there's often a sense of mystery surrounding the OC's origin or purpose, which adds to the intrigue of the story.
Yes, it is quite common. Fans are always eager to explore more of the world they love, and fanfiction provides an opportunity to do that.
Power struggle is a common theme. You have the super - powered beings from Prototype and the ghouls from Tokyo Ghoul, all vying for control or survival in a merged world.
One common theme is the struggle for identity. Female Kaneki, being both human and ghoul, constantly has to figure out who she really is. This is often explored through her interactions with both humans and ghouls, and how she feels like she doesn't fully belong to either group.
One common theme is power combination. Since both Naruto and Tokyo Ghoul have unique power systems, fanfics often explore how the ninja techniques and kagune powers can be used together. Another theme is the clash of cultures. The shinobi way from Naruto and the harsh reality of the Tokyo Ghoul world are very different.
The theme of redemption can also be present. Rize's actions towards Kaneki were quite cruel in the original story. Fanfictions may attempt to give her a chance at redemption, perhaps through her relationship with Kaneki. This could involve her showing remorse for what she did and trying to make amends in some way.
One common theme is love and sacrifice. Kaneki and Touken's relationship is often depicted as a deep, selfless love. They might be willing to sacrifice their own safety or desires for the other. For instance, Kaneki could put himself in danger to protect Touka from a powerful enemy.
