But I can't come up with interesting ideas...
Can you suggest something on Human/Alien?
Oooo I love this type of ship! Okie dokie!
1. A human raised in an Earthan purist community sneaks aboard a grounded merchant vessel while it’s unloading cargo on Earth. They’re found after the ship is already in deep space, and as a stowaway, they’re brought before the captain, a creature unlike anything human has ever seen. Though they’re scared and unfamiliar with the situation, they’re determined to stay on this ship, or at least not be returned home. As they get to know the captain and crew, they might just find out that everything they’ve learned about extraterrestrials is false
2. Human is the ship’s newest security grunt. They’ve worked the job long enough to know that their position is generally viewed as dispensable. They no longer see much point in building relationships with crew members who expect them die at the next planet, or with the security teammates they’ll inevitably mourn, so they do their job with their head down. But when a landing party accident leaves them confined to the sickbay for several days, they meet Alien, the ship’s medic, who seems thoroughly and genuinely concerned with Human’s care.
3. Mutinied by their crew, Human is marooned and left to die on an inhospitable planet. That is until Alien, marooned long ago and now adapted to the planet’s ways, comes to their rescue.
4. Alien is a planetary relations liaison, sent to Earth for a galactic peace gala. They’ve been studying up on their human social cues and language for months and things seem to be going perfectly, for themselves and the government figures they are guiding. That is until one of the human attendees, a boisterous and popular ship captain begins unabashedly flirting with them—helpfully pointed out by their new Earthan acquaintances. Human romance customs is one area of Earthan culture they did not prepare for tonight, and they have no idea what to do.
5. Human is abducted from Earth and forced to fight for the amusement of a nasty band of Space marauders. Earth is not the only planet they’ve raided, and in their new prison Human builds a friendship with one of their fellow captives. They find solace in each other and telling stories of their home planets, but at the same time they both are aware of the tension at the back of their minds. How can they trust each other when they could be pitted against each other at any moment? And how do either of them know their companion wouldn’t choose their own life over them?
6. Alien has been dating their human crew mate for about a month now. They are excited to share the news with friends while they’re home for a few days on shore leave, but the reaction is not what they were expecting. Their friends urgently inform them that humans are a species that eat their mates…and Alien has noticed them getting their mouth little close these couple weeks. They have to figure out how to break the relationship off without offending Human and fast.
7. Alien has been off-planet for several years in pursuit of a starship career. Along the way they met their beloved Human. Now they’re going back home to introduce Human to their family and organize the wedding. The only problem is even though they’ve mentioned the engagement, they have not brought up that their soon to be spouse is a human. They aren’t sure how their family is going to react or how Human will deal with their planet’s customs.
8. Alien is planetary royalty traveling to their race’s sister planet with whom they’ve had tensions. On arrival, they will meet their arranged partner, another royal, with whom they will forge a marriage alliance. Or that was the plan until Human, a space pirate, attacks their ship, taking Alien hostage and stranding the remainder of their crew.
9. Human has always been interested in the supernatural, cryptids, aliens, monsters, you name it. Even if people think it’s crazy, they want to believe. But it’s different when they actually get abducted by an alien. Just one. Who apparently did it on a dare and now has no idea how to get them home again without alerting the whole solar system, getting themself imprisoned and human put in a lab. So for now Human will have to stay with Alien and hopefully pull off their disguise as an alien.
10. Human has had a crush on Alien for as long as they can remember. But Alien has a strict personal rule against interspecies relationships, always loudly protesting about the difficulty of blending cultures and having different customs, beauty standards, instincts, and even biology. With such strong opposition, there is no way Human could ever tell them how they really feel.
