Backstory

Cyan worked in the specimen laboratory at MIRA HQ, occasionally taking trips off-planet for fieldwork and sample collecting. Cyan was very attached to her many pets, and would get engrossed in her work studying her specimens.

Unfortunately, she was caught alone in the specimen lab one day, and the impostor- Orange- who snuck into MIRA via transport vessel, sought to gain a new ally. Orange cornered and converted Cyan into an impostor by infecting her with the parasite, and once she turned, Cyan went into a feral hunger rampage, mindlessly killing and eating all of her pets and specimens in the lab. The grief of losing her beloved companions and all her work snapped her back into control of herself, only for Orange to praise her for the carnage. Outraged, Cyan turned on Orange, killing and eating him, too.

Not wanting to die for killing a seemingly innocent crew mate, Cyan outed herself immediately to her crew, handing over Orange's remains as well as their weapons during the meeting. Because Cyan never killed any actual crew mates, her crew decided to let her stay, on the condition that she be observed at all times via her Glitch Console (the Twitch pet lmao). She uses Glitch to stream her continued work in the lab, and keep in near constant contact with the rest of her team - it's also MIRA's way of keeping tabs on her, since she's on thin ice as a known impostor.

Cyan has a vitriolic hatred of other impostors, and can hardly conceive of another 'friendly' impostor like her existing. Whenever a hostile impostor shows up, all of her team have an alarm button on their tablets to call her, and 'deploy' Cyan to 'fix' the problem. This has regained some trust with her closest friends in her crew, though Cyan prefers to stay isolated in her laboratory with her new pets. She would love to find a cure for her condition, but is resigned to existing as she is, and it can't bring back the pets she lost. Cyan is soft on animals, robots, her fellow crew, and children, and has misused science lab equipment to make treats for young visitors. Don't mess with her work or she'll bite you.

Abilities

Cyan-tist is a Shapeshifter variant Impostor. She cannot turn into everybody she sees- however, she can transform into anything living she has ever eaten. The higher percentage of the creature she consumes, the better the disguise. She can shapeshift clothing from her own body matter. The 'cat hat' she once wore has become a physical part of her, the ears functional for hearing and movement, and the eyespots capable of sight, producing tears, and emoting.

Due to her initial feral rampage in the lab, Cyan can transform into a wide variety of crewmate pets and lab specimens- her favorites being the three forms of her former companions: a Doggy, a Headslug, and a Squig. She often uses these to spy on new arrivals undetected, attempting to sus out foreign impostors from the cohort. Cyan can adapt features to her existing body at any level she wants- for example, she can gain the fur coat of the Doggy, the wings of the Pouka or the Goose, or the tentacles of the Squig without needing to fully shapeshift. The Doggy form in particular has a heightened sense of smell, allowing her to detect if the scent of a foreign impostor is present, though it may not be sufficient to identify the specific individual from a crowd.

Cyan-tist's adaptive shapeshifting is powerful enough that she can gain the unique attributes of other impostors she has eaten. This includes her advanced chromatophores for changing color, which she acquired from Orange, the first impostor she killed and consumed. Very few impostors since Orange have had anything noteworthy to add to her repertoire of skills. Cyan swore to never eat a crew mate.

Completely self-indulgent Rodamrix Animated Series thoughts

Okay I couldn't help it, I wondered about what would happen if Cyan were to be present in the series. !!!SPOILER WARNING IF YOU HAVEN'T SEEN IT, DO NOT READ THIS PART!!!

Original series- If she didn't adapt to the sudden climate shift of the impostor takeover, or stood with the crew in any capacity when they began to spread out of control, Cyan-tist is most likely dead. She would not have gotten along with many- if any- of the impostors within MIRA HQ, and actively would have stood against or tried to kill them, making her an enemy. I can't imagine Big Purple let her live if she tried anything. If by some miracle she DID survive, Cyan is most likely operating as a plant within the impostor hideout, smuggling supplies or otherwise tipping off the survivors as to the movements of the horde so crewmates can escape or avoid being discovered.
