Well, in a Mass Effect - Starship Troopers fanfiction crossover, picture this. The advanced technology of Mass Effect, such as the mass relays and biotics, is introduced to the Starship Troopers universe. The Starship Troopers might be initially skeptical but then see the value in these new abilities. For example, the mobile infantry could learn to use biotics in combat. Meanwhile, the Mass Effect characters could be shocked by the brutal and straightforward combat style of the Starship Troopers. And perhaps there could be a common enemy that unites both universes, like a new alien threat that combines the worst aspects of the Reapers and the bugs.
There's no official connection between Mass Effect and Starship Troopers fanfiction. Mass Effect is its own distinct science - fiction universe with its own lore, characters, and storylines. Starship Troopers fanfiction pertains to the Starship Troopers universe. However, in the vast realm of fan creativity, someone might create a crossover fanfiction that combines elements of both, but this is not part of the official Mass Effect or Starship Troopers content.
One should look for unique concepts. Maybe it's a crossover that no one has thought of before, like 'Mass Effect and Discworld'. How would the magic from Discworld interact with the biotics in Mass Effect? Also, the pacing of the story matters. It should keep you engaged, not be too slow or too rushed, especially when introducing the different elements of the two universes.
First, know both universes well. For 'starship troopers', understand the military structure, the bugs, and the technology. For the other universe you're crossing with, study its key elements too. Then, create an interesting plot. Maybe a common threat that both sides have to face together. Keep the characters in - character as much as possible.
Well, in this crossover, perhaps the Covenant from Halo decides to take advantage of the chaos in the Starship Troopers' world. The bugs become a new target for the Covenant's religious zeal. Meanwhile, the Starship Troopers' soldiers and the Halo UNSC forces have to figure out how to deal with this new threat. They might start by sharing intelligence about the Covenant and the bugs. Some Starship Troopers could be trained by the Spartans in more advanced combat techniques. And in the end, they all team up to stop the Covenant's plans and also push back the bug hordes.
Character development is crucial too. Since it's a crossover, seeing how characters from both universes grow and change in response to the new situations created by the crossover. For instance, Shepard from Mass Effect having to deal with the more complex galactic politics of Stellaris. This makes the story more engaging and relatable.
One key element is how the powers and abilities are integrated. For example, how the Warframe's parkour and combat skills mesh with the biotics and tech in Mass Effect. Another is the interaction of the characters. It should feel believable when a Tenno meets a Shepard or other Mass Effect characters.
Definitely Master Chief from Halo. His skills and leadership would be a great addition to the Starship Troopers' universe. Also, Rico from Starship Troopers. He could learn a lot from Master Chief. Their interaction would be really interesting to see.
One great 'starship troopers crossover fanfiction' I read was a crossover with 'Aliens'. It had really intense battle scenes where the troopers from 'starship troopers' teamed up with the marines from 'Aliens' to fight off a huge horde of bugs and Xenomorphs. The author did a great job of mixing the two universes' technologies and combat styles.
Well, Master Chief would likely start by assessing the threats in the Mass Effect universe. He'd notice the Reapers right away as a major threat. His military training would kick in, and he'd try to find ways to combat them. In terms of adaptation, he'd probably look for allies. He might be initially skeptical of the alien species but would soon realize that they can be valuable partners. For instance, he could team up with the Turians, who also have a strong military tradition. He'd also have to adapt to the different forms of transportation, like the Mass Effect relays. His first encounter with using one of these relays might be a bit of a shock, but he'd quickly figure out how to use it to his advantage.
One interesting concept could be the exploration of different alien species in more depth. In fanfiction, authors might create new types of bugs with unique abilities or behaviors that weren't fully explored in the original. Another concept could be the expansion of the relationships between the soldiers. For example, how they form deeper friendships or rivalries outside of the main battles.
