The struggle against evil is a big theme as well. Just like in the original 'the mortal instruments' series, the ocs often find themselves in the middle of battles against demons or other dark forces. They have to learn to fight and use their skills to protect themselves and those they care about.
Power and its implications are also common themes. The ocs may have unique powers or abilities that they need to learn to control. This can lead to conflicts with other characters or organizations. Also, the theme of belonging is prevalent. The ocs are outsiders at first, and they strive to belong to the Shadowhunter community.
One common theme is the struggle between love and duty. Jace has his responsibilities as a Shadowhunter, and the OC often has her own goals or loyalties. Their relationship has to navigate these obstacles.
One common theme is the exploration of different character relationships. For example, there are many fanfics that focus on the relationship between Clary and Jace, either expanding on their romantic relationship or exploring a different dynamic between them.
One common theme is the exploration of forbidden love. Since they are Shadowhunters with complex rules and hierarchies, their relationship often has elements of being forbidden, and the kiss can be a symbol of defying those norms. Another theme could be the power of their connection. The kiss might be seen as a way to transfer or share some kind of power, whether it's magical or just the power of their strong emotions for each other.
One idea could be creating an OC who is a half - angel, half - demon. This would bring a unique perspective to the story as they struggle with their dual nature in the world of the Mortal Instruments. They could be on a quest to find a way to balance their two halves and in the process, interact with the main characters in unexpected ways.
First, study the existing Mortal Instruments universe. Know the rules, the different species like Shadowhunters, Downworlders, etc., and the lore. Then, create your OC. Decide on their appearance, personality, and backstory. For example, if your OC is a Shadowhunter, think about their family, their training, and any special abilities they might have.
Sure. 'City of Shadows' is a great one. It has a really interesting original character who gets involved in the Shadowhunter world in a unique way. The character development is well - done and it fits right into the existing lore of 'the mortal instruments'.
One common theme is power dynamics. The OC often has to navigate their new - found relationships within the harem while also dealing with the power - hungry and often violent world of Mortal Kombat. Another theme is loyalty. Characters in the harem might have different loyalties, like to their clans or to their own personal vendettas, which the OC has to handle.
The OC could have a power related to nature. In the Mortal Instruments world, most powers are related to combat or magic in a more traditional sense. So, an OC with the ability to communicate with plants and use them as allies would be unique. For example, they could make vines grow to trap enemies or use the essence of certain flowers to heal wounds. This power would set them apart from the other characters and create interesting scenarios when interacting with Jace.
Another theme is loyalty and friendship. The stories might show how Sheeva and the OC form a bond, whether it's through fighting side by side in battles or helping each other out in the Mortal Kombat universe. It could also involve themes of betrayal if one of them has to choose between different loyalties.
One of the main themes is discovery. The OC discovers the world of Mortal Kombat through Jade, and Jade discovers new aspects of herself through the OC. There's also the theme of redemption. Maybe the OC has a troubled past and Jade helps them find a new path. Additionally, survival is a big theme. They have to fight together to survive in the dangerous Mortal Kombat tournaments and against the various villains.
