Space Colony features a cast of 19 crew members, though not all appear at once in the colony. They carry with them a wide variety of tropes of their own:
A Coloradan woman who serves as the team leader.
- Blessed with Suck: She doesn't have any single needs that dominates her mood. While this sounds good on paper, it means that you can't just boost that need for a quick and dirty mood booster
- The Hero: She's the main character and usually the one that pulls you through a mission.
- Jack of All Stats: She starts with average levels in all basic skills, and lesser levels in some others.
- Only in It for the Money: She just wants to survive long enough to collect her paycheck and finally retire.
- Only Sane Man: She's the only member of the team without some sort of personality defect or eccentricity.
A Norwegian biker brought on to help operate heavy machinery.
- All Bikers are Hells Angels: Mostly averted, despite the look and some Nordic motorcycle gangs having connections to the Hell's Angels. The worst he gets up to is being rude.
- Badass Biker: His Goal is to make enough money to support his gang back home.
- Big Eater: His priority want is food.
- The Big Guy: And it shows. Aside from him being a Big Eater, he's also a good mechanic and turret operator.
- Bunny-Ears Lawyer: A little too eccentric to be classified under Only Sane Man but he's reliable with a decent amount of skills.
- Fire-Forged Friends: Him and Venus have a long history of getting through crap assignments.
- The Lancer: Has this role when he's on the same mission as Venus.
A Texan woman brought in to aid with cleaning duties.
- The Alcoholic: To the point she was piloting a shuttle while drinking
- Almighty Janitor: Almighty is being very generous. But she's great when assigned as a dedicated Janitor.
- Dysfunction Junction: She seems to have a combination of alcoholism and depression, as well as a tendency towards self destructive behavior and lashing out against others. Her priority need is for social contact.
- The Friend No One Likes: The very first campaign mission is both Stig and Venus cursing that they have to have her on this mission.
- I Just Want to Have Friends: Ultimately she wants people to talk to but she's so neurotic she drives them away.
- Smoking Is Cool: Subverted. She's a protagonist, but smoking doesn't seem to help her problems.
A Californian man brought in as the team doctor.
- Bunny-Ears Lawyer: Hoo boy.
- Damn, It Feels Good to Be a Gangster!: He acts like this anyway. His father threw him into a private school when he started to hang around actual gangbangers as a kid.
- Jive Turkey: He has mild elements of this. Justified in that he pretends he's a gangster despite being from a well to do upper middle class family and a skilled medical student.
- Neat Freak: To some extent, understandable, since he's a doctor. His priority need is cleanliness.
- The Medic: Due to his background, he starts with the highest medical skills of any character in the game.
A Californian woman brought in to help with the colony's botany.
- Actual Pacifist: Has no skills in anything military or in space chicken farming.
- Granola Girl: And how!.
- New-Age Retro Hippie: Future Retro Hippie, in fact.
An American man from the Deep South brought in to help run the colony's space chicken farming operation.
- Deep South
- Gentle Giant
- Idiot Savant: Not exactly, but he is an extremely competent chicken farmer despite his otherwise dull nature.
A Valley Girl brought in to — well, do janitorial work and learn something.
- Dumb Blonde
- Like Is, Like, a Comma
- The Ditz: So much so that she has one of the slowest learning times and has literally only one skill in a game with dozens of them.
- Valley Girl
A former British navyman kicked out of the Navy for some unknown offense, which he says was a "silly incident". He is brought in to help man the turrets.
- Older Than They Look: His portrait and sprite looks a lot younger than his supposed age of 55. He doesn't even have a strand of white hair.
A Jerkass extraordinaire who's high maintenance and mixed in skills.
- Casanova Wannabe: Greg fancies himself a ladies man, but he has no real luck with women, because they quickly realize that is quite sexist. Venus also expresses frustation over his constant attempts at propositioning her.
- Jack of All Stats: A weaker version thereof.
- Jerkass
- Leader Wannabe: Greg describes himself a "born leader", but the Psychiatrist AI heavily disagrees, finding his sexist attitude and disregard for the feelings of others to be huge liabilities, to say the least.
Two Japanese twins brought in to help with general purpose work and operations.
- Bridge Bunny: With their need for proximity, it's usually best to just set them to power and oxygen and leave them there.
- Cyberpunk: Their outfits seem to be Japanese versions of this fashion.
- Tag Team Twins: Oh yeah. They work far better together than apart, and can satisfy each other's social needs effectively.
A former Vice President of Sales at Blackwater Industries, brought in to help the colony's general operations.
- Corrupt Corporate Executive: She works for Blackwater, nuff said.
- Frontline General: Frontline Executive anyway. She's right there in the thick of things with everyone else. Not by choice mind you, but she still does what is needed.
- Mean Boss: What keeps her from being a Bad Boss is the fact she's far more competent and pragmatic to qualify.
A Violent Glaswegian brought in to help operate the team's heavy machinery and turret guns.
- Bald of Evil
- Off on a Technicality: His background profile mentions he did a stint on death row, but was able to evade getting the death penalty and securing his release due to "a technicality".
- Violent Glaswegian
A Ukrainian man brought in to aid the team's biochemical and scientific endeavors.
- Insufferable Genius
- Mad Scientist
- Neat Freak: Like Dean, his priority need is cleanliness.
A British woman and former athlete brought in after an injury ended her career. She is still quite athletic, being known as the sporty one of the team. She aids with a wide variety of duties, including turret operation.
- Retired Badass: Involuntarily and prematurely, in her case.
- Evil Counterpart: To Candy, in some ways.
- French Jerk
- Rich Bitch: Even more so than Barbara.
A Greek man who was the victim of some unknown psychic attack (possibly from the Brainspawn), that rendered him emotionless and a Cloudcuckoolander. He starts with few skills, but is a good learner.
- Meaningful Name: The only thing that satisfies his entertainment need seems to be the observatory, i.e. looking at the cosmos.
A middle class white New York City boy pretending to be a lower class black boy and gangster. An avid rap fan who begins with few skills but has the big advantage of using his skateboard to get around the base rather than walking, greatly adding to his speed.
- Jive Turkey
- Only One Name
- Parental Abandonment
- Pass Fail: Hoo booooooy.
- Pretty Fly for a White Guy
- Satisfied Street Rat: His attempted persona.
- Shout-Out: To Slim Shady, of course.
An old Indian woman brought in as the team janitor and for moral support.
A Chinese Grumpy Old Man and old robotics specialist who minors in botany.
- Crippling Overspecialization: He is excellent at botany and masterful at android making, but literally has no other skills and is high maintenance. On the plus side, he is a fast learner.
- Grumpy Old Man
- Old Master
