One interesting concept could be the combination of different power sets. For example, a space marine's combat skills combined with the dreadnought's heavy firepower in unique battle scenarios. Another might be the exploration of the relationship between a space marine who is transferred into a dreadnought and how they adapt to their new form.
Some concepts include the use of the dreadnought as a sort of last - resort weapon in a space marine's arsenal. In fanfiction, it could be that a space marine is only placed into a dreadnought when all other options are exhausted. There are also concepts related to the dreadnought's upgrades. Fan authors might write about how a space marine's knowledge and skills could be used to improve the dreadnought's capabilities, like enhancing its targeting systems or making its armor more resilient.
One popular character is Marneus Calgar. He's a well - known space marine character, and his inclusion in a dreadnought crossover can bring in a lot of his leadership and combat abilities. Another could be Dante. His long - standing reputation in the Blood Angels chapter makes him a great candidate for such crossovers.
Well, a cool space marine crossover fanfiction idea could involve crossing them with superheroes. Picture a space marine teaming up with Superman to fight an intergalactic threat. Or perhaps a crossover with the Predator universe. The space marines' combat skills and high - tech gear against the Predator's hunting skills would make for an exciting story. Also, a crossover with the Warhammer Fantasy world, bringing the space marines into a world of magic and medieval - like warfare.
One interesting concept could be the combination of different alien species from various sci - fi universes with the Space 1999 setting. For example, mixing the Goa'uld from Stargate with the Moonbase Alpha crew. It could create really unique power dynamics and storylines.
One idea could be a crossover with the Warhammer 40K Imperium forces where a group of Chaos Space Marines infiltrate an Imperial stronghold. They could face off against Space Marines of the Ultramarines chapter, leading to intense battles and moral dilemmas for both sides. Another idea is a crossover with a fantasy setting like the Elder Scrolls. The Chaos Space Marines could find themselves in Tamriel, causing chaos among the different races and factions there. They might encounter the powerful mages or the warrior guilds.
One interesting concept could be the combination of the Flood from Halo and the Necromorphs from Dead Space. Imagine how the two different types of parasitic, body - transforming threats would interact. Another concept might be the technology exchange. For example, how would the UNSC weapons and armor function in the Dead Space universe, and vice versa with the Dead Space engineering and weaponry in the Halo universe.
In some One Piece marine fanfiction, there are concepts about marine - pirate alliances in secret. This goes against the normal narrative but creates a really interesting dynamic, as it makes you wonder about the possible reasons behind such alliances, like mutual benefits in a particular situation or a hidden agenda that might be beneficial for both parties in the long run.
One interesting concept could be the combination of Naruto's ninja skills with the Doom Marine's combat style. For example, Naruto's shadow clone jutsu might be used in a creative way in the Doom universe, like sending clones to scout out areas filled with demons while the Doom Marine focuses on direct combat. Another concept could be the power - up system. In Naruto, characters gain new powers as they progress, and this could be integrated into how the Doom Marine becomes stronger in the fanfiction, perhaps by obtaining chakra - like energy sources.
In this type of fanfiction, the role - playing aspect within the Marine world is a great concept. OCs can take on various roles like a Marine scientist, an undercover agent, or a front - line combatant. The fanfiction might explore how these different roles interact with each other. For instance, a Marine scientist OC might develop new technologies to combat pirates, which then affects the strategies of the combatant OCs.
Well, a great concept is how these OC marines interact with the main characters from the Mass Effect series. They could be mentored by Shepard, or perhaps they start off as rivals but later become comrades. Their integration into the existing narrative is key. For instance, an OC marine might have a crucial role in a battle that was only briefly mentioned in the original game. This gives the fanfiction a chance to expand on the lore and create a more immersive experience for the readers.
One interesting concept could be the merging of Dead Space's terrifying necromorphs with the characters or settings from another universe. For example, if there was a crossover with a science - fiction series like Star Trek, seeing how the Starfleet crew would handle the necromorph threat would be really cool. They have different technologies and ethics, so it would create a lot of conflict and new storylines.
