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.
There might be a fanfiction where a group of Imperial Guardsmen encounter a Necron tomb world awakening. This story could explore the horror and confusion of the guardsmen as they face the ancient and powerful Necrons, and how they try to survive against overwhelming odds. It could also show the Necrons' view of the 'inferior' organic lifeforms.
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 idea could be an Necron Overlord who rebels against the Silent King's plan. He might start to form alliances with other races in secret to gain power and knowledge. This could lead to a whole new set of power dynamics in the Warhammer universe.
One interesting concept could be the evolution of the factions. For example, how the Space Marines might have developed new combat tactics or even new genetic enhancements. Another could be the exploration of new planets and the strange alien species that might be discovered. Also, the political intrigue within the Imperium could be a fascinating aspect, like the power struggles between different segments of the military or the Adeptus Terra.
Some interesting concepts in Warhammer 30k fanfiction include the loyalty and betrayal within the legions. There are stories that show how a single act of betrayal can have far - reaching consequences for an entire legion. The psykers in this setting also offer great potential for fanfiction. Their powers and how they are controlled or go out of control can be the focus of many stories. Additionally, the relationship between the Space Marines and the Mechanicum is another area that fanfiction often explores, with different takes on their cooperation and conflicts.
Well, the idea of power - gaining in Warhammer 40k si fanfiction is quite cool. A self - inserted character could potentially gain psychic powers and have to learn to control them in a universe where such powers are both feared and respected. And the technology aspect is fascinating too. They might get their hands on some ancient and powerful weaponry or technology from a lost civilization. Plus, the fanfiction often delves into the relationships between different characters. An si character could form an unlikely alliance with a Space Marine or a Rogue Trader, which would be full of drama and adventure.
One interesting concept could be the combination of RWBY's unique semblances with the grimdark and highly militarized setting of Warhammer 40K. For example, a character with Ruby's speed semblance might be an extremely effective scout or assassin in the 40K universe. Another concept could be the clash of the different factions in 40K with the teams from RWBY. The Imperium's strict dogma and the more free - spirited nature of RWBY characters could lead to some really engaging storylines.
One interesting concept is the idea of a character being reborn with their past memories intact. This can lead to some really cool storylines where they use their knowledge of the past to change the course of events in the Warhammer 40k universe. Another concept could be the reincarnation of a powerful hero or villain, which can completely shift the power dynamics in different factions.
One interesting concept is the idea of perpetuals themselves. They are immortal beings in the Warhammer 40k universe. In fanfiction, they can be explored in various ways, like their relationships with other factions. For example, how a perpetual might interact with the Imperium, either as an ally or a potential threat.
One interesting concept is the crossover with other popular sci - fi universes. For example, a crossover with Star Wars could have the Imperium of Man facing off against the Galactic Empire. Another concept could be the combination of different Warhammer 40k factions in unexpected ways within the fanfiction. Maybe the Space Marines teaming up with the Orks against a greater threat.
