One idea could be to explore Imhotep's life before he became the mummy. Maybe he was a brilliant architect with a secret love interest that influenced his actions later. Another could be a story where an OC helps Imhotep break free from his curse in a different way than in the movies. For example, the OC has a special magical ability that can nullify the dark magic binding him.
A great idea for an Imhotep OC fanfiction is to make the OC a priestess who was once Imhotep's friend. She could have been there when he made his fateful decision to resurrect his love. In the fanfiction, she tries to persuade him not to go down that dark path. When he is cursed, she devotes her life to finding a way to save him. This could involve her going on a journey, facing many challenges, and having to make difficult choices between her loyalty to Imhotep and her duty to the gods.
Well, you could create an Imhotep OC fanfiction where the OC is a time - traveler from the modern day who accidentally gets sent back to Imhotep's time. The OC could initially be terrified of Imhotep but then realizes that he has a more complex personality than just being a villain. They could form an unlikely alliance and the OC could use modern knowledge to help Imhotep achieve his goals in a more positive way, like building a better society instead of seeking revenge.
One interesting storyline could be Imhotep and Evelyn teaming up to fight a new, more powerful ancient evil. Maybe they discover a prophecy that only their combined knowledge of the old and new worlds can stop it.
One plot idea could be that in a modern - day setting, Harry, who has a submissive nature, stumbles upon an ancient artifact that somehow links him to Imhotep. Imhotep, with his dominant personality, tries to use Harry for his own purposes at first, but as they interact more, they develop an unexpected bond. Harry might start to learn about Imhotep's past and secrets, and Imhotep could be intrigued by Harry's modern - world knowledge.
Well, an interesting Watchmen OC fanfiction could center around an OC who is a former sidekick of one of the main heroes. This OC could be struggling with the legacy left behind by their mentor. They might have a different moral code compared to the other characters in the Watchmen universe. Also, an OC who is an artist that uses their work to comment on the state of society in the Watchmen world, like Rorschach's journal but in a more public and creative way.
One idea could be creating an OC that is a hybrid of two different Pokemon types. For example, a half - water, half - electric type with unique abilities.

Also, you could have an OC from a different region with a completely new set of Pokemon not seen before in the main series.
One idea could be to create an oc that represents a small, newly independent nation. Show their struggles and triumphs as they find their place in the world of the countryhumans. Another idea is to make an oc that is a hybrid of two existing countries, with a unique culture and set of values. For example, an oc that is half - France and half - Italy, and how they interact with the other countryhumans.
You could also create an OC who is a spy sent to infiltrate the Darkling's inner circle. The OC has to balance their mission with their growing feelings for the Darkling, which makes for a complex and engaging story.
Well, you could have an OC that is a skilled hacker who gets involved with the Phantom Thieves by accident. They might have a Persona that represents a famous code - breaker from history. Also, an OC who is a foreign exchange student from a country with a very different cultural background could bring in new elements to the fanfiction. Their Persona could be influenced by their home country's folklore. Maybe an OC who is a prodigy artist and uses their art skills to create powerful items in the Metaverse, with a Persona related to a great artist from the past.
One idea could be a Garou OC who is a lone wolf, not part of any pack, and has to survive in a world full of both human and supernatural threats. They could have unique powers like the ability to blend into shadows, which helps them in their solitary existence.
Well, you could write a fanfiction about a Marvel OC who is from an alternate dimension where the roles of heroes and villains are reversed. This OC comes to the main Marvel universe to try and right the wrongs in their own dimension. Or perhaps an OC who is a young Asgardian with a gift for magic that Odin tries to keep hidden for some reason, and the OC has to navigate the politics of Asgard while also dealing with their emerging powers.
One idea could be an OC who is a spy sent to infiltrate Doflamingo's organization. This OC could have a hidden past that slowly gets revealed as they gain Doflamingo's trust. Another idea is an OC with a special power that Doflamingo wants to control or use for his own evil plans. For example, the OC might be able to manipulate time in a small area, which could be a great asset in battles or heists.
