Perhaps the OC is a witch doctor who was once a human but was cursed herself long ago. She has been living in the bayou, half - human half - something else. When she meets the princess - frog, she sees a chance to break her own curse as well. So she decides to use her combined knowledge of both human and non - human magic to fight against the forces that keep the princess in her amphibian form. This could involve a complex plot of self - discovery and redemption for both characters.
Another way of interaction could be through conflict. The Witch Doctor OC might have different ideas about how to break the curse compared to the other characters. This could lead to arguments and power struggles. Maybe the OC thinks that a more aggressive approach is needed, while the princess and the frog prince prefer a more gentle, love - based solution. This conflict could drive the story forward as they try to find a middle ground.
One plot could be that an original character (oc) is a time - traveling thief who accidentally steals a crucial component from the Doctor's TARDIS. The 12th Doctor has to track this oc down across different time periods. As he does, he discovers that the oc has a tragic past that led them to a life of thievery. The Doctor decides to help the oc instead of punishing them, and together they face a threat that was awakened by the stolen component.
One idea could be exploring a different backstory for the frog prince. Maybe he was cursed not just by a witch but also had some sort of connection to a long - lost magical realm. In the fanfiction, the princess could discover this as she tries to break the curse, adding more depth to their relationship.
One possible plot could be an OC who is a young witch hidden in the human world. She discovers that she has a special power that could either save or destroy the balance between witches and humans. The OC crosses paths with the last witch hunter and at first, they are enemies. But as they face a common, greater evil like an ancient, dark magic that threatens to consume both their worlds, they must learn to work together. This could involve the OC teaching the witch hunter about the more nuanced aspects of witchcraft, and the hunter protecting the OC from those who would harm her for being a witch.
Maybe the OC in the fanfiction is a witch herself but wants to help Hansel and Gretel fight the bad witches. She has to hide her identity at first. As they hunt witches, she gradually gains their trust by using her knowledge of witchcraft to outwit the evil ones. And in the end, they all form a strong alliance.
The plot could start with Naruto discovering an ancient art of witch doctoring. He might find a hidden scroll or meet an old hermit who teaches him. Then, he uses his new skills to heal his friends who were injured in a battle. For example, he could create a special potion to revive a nearly dead comrade. As he delves deeper, he realizes that there are dark forces at work that only his witch doctor skills can combat.
One idea could be a story where Tiana and Naveen have to face a new magical threat in New Orleans. Maybe a dark voodoo priestess tries to steal their happily - ever - after. Another idea is to write about their life after the movie, like how they run the restaurant together and deal with new challenges in the city.
Well, you could have a witch OC fanfiction where the witch is an outcast among her own kind. She doesn't believe in the typical evil ways of witches and wants to use her powers for good. So she approaches the DWMA with an offer of peace and cooperation. Another plot could be that the witch OC has a hidden lair where she collects ancient artifacts that have the power to change the balance between witches and the DWMA. And a third plot idea is that the witch OC is in love with a DWMA student, and this forbidden love creates a whole lot of drama and challenges as they try to be together in a world where witches and DWMA are usually at odds.
One idea could be an OC who is a transfer student from a far - off magical land. She has unique magical abilities that the other students haven't seen before, like the power to communicate with magical creatures in their own languages. This could lead to her helping the school when a group of mischievous magical beasts invade the academy.
One idea could be that the OC is a new tenant in the Amamizukan. She has a unique skill, like being able to communicate with sea creatures in a special way. This could lead to some comical and heartwarming moments as she tries to share her knowledge with the other residents who are all otaku in their own ways.
