A unique take on the crossover concept. For example, if it combines the dark, gritty atmosphere of Doom with the epic sci - fi world of Halo in a creative way. Maybe it has the Doomguy in the Halo universe facing off against Covenant forces, that would be really cool.
Well - developed characters are key. If the author can take the existing characters from both Doom and Halo and give them new depths, like exploring the Doomguy's reaction to the Halo technology or Master Chief's view of the demonic threats from Doom. Also, a good plot that keeps you on the edge of your seat, whether it's a fight for survival or a mission to save both universes from a new threat.
The fanfic can be interesting if it delves into the lore of both games. It could explore how the different mythologies and backstories of Doom and Halo interact. For instance, how the Hellish forces in Doom might relate to the Forerunners in Halo. It could also introduce new concepts that are a blend of both universes, creating a rich and engaging story world that fans of both games can enjoy.
Well, it's interesting because it allows for new character interactions. Imagine a Spartan from Halo teaming up with Ruby from RWBY. Their different skills and personalities would make for an engaging story. Also, the contrast between the two universes' aesthetics, like the gritty, mechanical look of Halo and the more colorful, anime - inspired RWBY, adds to the appeal. Fans of both can see how their favorite elements mesh together, whether it's the Covenant vs the Grimm or the Spartans using their advanced weaponry in the RWBY world.
The combination of two very different universes. Naruto has its ninjas, chakra, and unique cultures, while Halo has advanced technology, space battles, and super - soldiers. When these two are mashed up in a fanfic, it creates a whole new set of possibilities. For example, seeing how a Spartan would fare against a powerful ninja like Sasuke.
The clash of different powers and personalities. For instance, when the Doom Patrol crosses over with another team, like the Teen Titans. The Doom Patrol has these really strange and out - there powers, like Crazy Jane's multiple personalities each with their own powers. When combined with the more straightforward powers of the Teen Titans, it creates really unique storylines.
You can start by looking on fanfiction websites like Archive of Our Own. There are often a plethora of Doom x Halo fanfics there. Just use the search function and type in 'Doom x Halo' to filter out the relevant stories.
The character of Serena herself makes 'halo wars serena fanfic' interesting. She has her own unique personality and abilities in the Halo Wars universe. Fanfic writers can explore different aspects of her character, like her backstory or her potential for growth.
One idea could be a scenario where the Doom Slayer somehow ends up in the Halo universe. He might team up with the Master Chief to fight a common enemy that combines the demons from Doom and the Covenant or Flood from Halo. For example, a new threat that has the ability to corrupt both the technology in the Halo universe and summon Doom demons.
Perhaps a crossover with a fantasy world. Doomguy enters a realm filled with magic, elves, and dragons. He might initially be seen as an outlander, but as he battles the demons that have also invaded this fantasy world, the inhabitants start to see him as a valuable ally. The clash between Doomguy's advanced weaponry and the magic of the fantasy world would be a fascinating aspect to write about.
One interesting crossover could be Master Chief meeting Iron Man. They are both iconic in their own universes. Master Chief with his Spartan strength and combat skills, and Iron Man with his high - tech suits. They could team up to face a common enemy that threatens both the Halo and Marvel universes, like an interdimensional threat that is after the advanced technology in both worlds.
One possible plot could be that the UNSC discovers a derelict Xenomorph-infested ship while on a routine exploration mission in Halo space. The Spartan soldiers have to fight off the Xenomorphs while also trying to figure out how they got there and if there's a connection to the Forerunners. Maybe the Xenomorphs are being used as some sort of biological weapon by an unknown faction.
Maybe the Forerunners in the Halo universe somehow cross paths with the Dust - the energy source in RWBY. This could lead to a power struggle or an alliance based on the unique properties of Dust. The characters from RWBY might use their Semblances in combination with Halo technology for some really cool battles.
