Purple is a purple-colored, short, astronaut-like creature. They wear a navy blue cap and shirt, with a gold badge and darker blue tie. They have a purple backpack. Purple is often on high alert ever since an accident with Red a while ago, keeping them on their toes. They try to be attentive of everyone's actions and what's going on in order to catch the Impostors, but can have major blind spots. They can be very secretive, but aren't very good at being subtle about it. Purple can be smart and resourceful when they want to be. In fact, Purple, as proclaimed by Green, is one of the smartest and most sensible Crewmates on the ship. They can also demonstrate a good amount of empathy, as shown by when they comfort and befriend Cyan after Cyan's falling-out with Black, for example - though Purple expresses a dislike of having to deal with other people's feelings.Their past with Red affects how they interact with others. Purple holds resentment towards Red throughout the whole season and refuses to work with them, even to the point of being counterproductive. Though, at the end of the show, the two manage to reconcile and Purple begins to view Red more favorably.

Orange was an orange-colored, short, astronaut-like creature wearing an orange backpack and brown jacket with a white undershirt. They were very loyal to MIRA and always reminded the other Crewmates about the MIRA guidelines. Even after being possessed and caught, they still priorize having a group vote before being ejected. They often adopted an overly cheerful demeanor, being welcoming yet clumsy.When possessed, they became incredibly caring, worried, and obsessed with keeping the Ore+ safe, even acting maternal towards them. Orange referred to the Ore+ as their "babies", foreshadowing how the Ore+ was actually alien eggs (and their secret identity as Impostor).Orange was also quite incompetent, being unable to kill any Crewmates excluding Lime in front of the whole Crew, as explained by Green. They were also easily persuaded into checking the trash chute before being somewhat surprised after Red purposefully pushes them in.

While disguised, Green was a green-colored, short, round-bodied astronaut-like creature wearing a green backpack and a dark green hoodie with a brown hat. Green, during their time alive, was shown to have a "can-do" personality, doing as much work as they could to the best of their ability. They are demonstrated to have a kind and friendly demeanor, but are also non-confrontational, After being possessed by The Impostor, they became a mastermind who had killed every Crewmate, except for the duo of Red and Purple who survived, Yellow who was voted out of the ship after being framed, and Lime who was killed by Orange. They were very cruel and distasteful to kill Crewmates, ripping Blue's face off and cutting Brown's body into pieces. They appeared to be greedy for kills and uncaring for their offspring, as they express the wish to kill everyone by themselves, saying that their offspring would only get in the way.

Red is a red-colored, short, round-bodied astronaut-like creature wearing a red backpack, a dark red airline pilot uniform with a single yellow button on it, and a dark red pilot hat with a yellow trim. Red is an arrogant, and wildly incompetent captain, heavily relying on the MIRA handbook, as well as their status as captain. Red prioritized their reputation and status as captain of the Skeld. Red had a "by the book" attitude, appearing as "MIRA's bootlicker" and always following the system,

Black was a dark-gray colored cybergoth Crewmate who wore black mascara and darker-gray eyeshadow perfected into a wing shape at the end, along with a spikey choker with a bell on it Black was not typically very emotional, adopting a calm and unbothered demeanor a majority of the time. They could be blunt, especially if someone was getting on their nerves Black was dedicated to their job as a geologist, regularly studying the Ore+ for damage

They were a cyan-colored Crewmate who wore a pink-to-blue tie-dye shirt, a pink headband/flower crown, and a blue crystal as a necklace Cyan was the typical hippie character who liked talking about gems, crystals, vibes and tarot cards, even calling themselves a gemologist. Despite being a ditzy, they were nice and tried their best to keep everyone feeling positive, They were also sensitive, as shown when Black yelled at them and then Cyan started crying, but later they started to form a friendship with Purple. Even though they felt better afterwards
