In some fanfictions, Eldar characters might be paired with a Necron Lord OC. This creates an interesting dynamic as the Eldar are a very different and ancient race. They could be either enemies, with the Necron Lord OC seeing the Eldar as a threat to their plans, or they could form a tenuous alliance based on a shared goal, like stopping a Chaos incursion.
One interesting storyline could be the Necron Lord OC's struggle to regain their former glory in a universe that has changed much since their slumber. They might have to face new and powerful enemies while also trying to unite the disparate Necron factions under their rule.
One popular Necron OC is 'Xarion'. He is often depicted as a Necron lord who has regained some of his former emotions and uses his strategic mind to outwit his enemies. Another is 'Lythia', a female Necron who has a unique bond with a group of Eldar. She tries to find a balance between the Necron's cold logic and the Eldar's more fluid way of thinking.
One common character paired with 'female Luffy' is Zoro. In some fanfictions, their relationship could be more of a romantic nature. Zoro might be the first one to notice the changes in Luffy when she reveals her female side, and then they start to develop a deeper connection. Their dynamic would be different from the original, with more of a romantic tension added to their usual banter.
Optimus Prime is sometimes paired with baby Soundwave. Their interactions can be really interesting as they come from opposite sides. Optimus might take on a mentor - like role towards baby Soundwave, teaching him about things like morality and the value of life.
Stan can also be paired with Kenny. Stan's more moral - centered character can contrast with Kenny's somewhat nihilistic view of his own mortality. In a crossover with a post - apocalyptic world, Stan might be trying to find a way to save humanity while Kenny is just along for the ride, but still manages to survive in the most unexpected ways.
Cheelai and Lemo from the Broly movie might also be paired with the reincarnated Broly. They could act as his guides or friends in the new world he finds himself in, helping him navigate the complex politics and power dynamics of the Dragon Ball universe.
One common theme is self - discovery. The OC often discovers new things about themselves while being paired with Harry. For example, they might find out they have a hidden power or a different view of the wizarding world. Another theme is friendship evolving into love. The relationship between Harry and the OC usually starts as friends and then develops into something more romantic as they face challenges together, like fighting against Voldemort or other dark wizards.
Another character that might be paired with Shan Yu's OC is Li Shang. Their military leadership styles could clash or, in some cases, complement each other, leading to a story full of power struggles and strategic maneuvers.
Often, characters like Zuko could be paired with the oc son of Azula. Zuko, as her brother, might play a role in either guiding or conflicting with the son. He could be a source of wisdom or a reminder of the family's complex history.
Another character he could be paired with is a child of Poseidon. The contrast between Apollo's domain of light, music and healing and Poseidon's domain of the sea would create a lot of room for conflict and cooperation. They could go on adventures together, with the oc son of apollo using his powers to heal any injuries during their quests and the child of Poseidon using their water - related abilities to navigate or fight.
