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.
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 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.
The appearance and customization of Necron OCs can be really cool in fanfiction. They could have different color schemes or unique body modifications compared to the standard Necrons. For instance, an OC might have a more organic - looking part on their body as a remnant of their pre - Necron existence. Their personality also matters. A Necron OC could be more curious about the galaxy than the typical emotionless Necrons, leading them to explore places and engage in situations that normal Necrons wouldn't.
