i’m sure everyone is already doing this, but here is the star trek series that i had been building in my head for probably 10 years:

• the captain is the 1st romulan in star fleet. she’s a really solid captain, and she’s kind of everything you wouldn’t expect from a romulan - she’s personable and close with her crew. most of the time she’s able to keep her romulan temper under control, but she deals with a lot of racism, so sometimes she flips her shit and it is terrifying.
  
• the chief engineer is a changeling, and they’re agender and very happy to be a changeling, thank you. they’re really into experimenting with different forms, and (thanks to improved cgi) they utilize their gelatinous form to get all up in the workings of the ship
• the first officer is the token human. he is indian, obsessed with rare alien artworks, and aromantic pansexual. he basically is interested in sleeping with any being with two legs (and some with fewer or more than two legs), but not interested in dating.
• chief medical officer is klingon. (KLINGONS HAVE TO HAVE MEDICS, TOO, OKAY.) she is very aggressive in her treatments but is totally a giant softie underneath. she was actually super-talented in battle and won a bunch of prizes growing up, but she has always hated fighting (she tries to keep this under wraps, though, and has a tendency to threaten to chop people’s heads off with bat’leths).
• those are all the characters i’ve come up with so far, lemme know if you’ve any ideas

the crew isn’t very well-respected in star fleet, in fact, they were given a not-so-great ship (that the lovely changeling chief engineer has upgraded leik wo), and are usually handed all the mucky jobs, especially ones that tiptoe the line of federation ethics (well, there’s a romulan captain. she’s probably okay with that, right? says star fleet brass, with their heads up their asses). despite inadequate support (and often inadequate supplies), this crew tends to scrape through incredibly difficult situations and generally kick ass in unorthodox ways.
