Overview
Plasmics are a space-faring species of sentient gelatinous lifeforms. During a normal interplanetary flight (similar to international flights on Earth), something went wrong and the ship crashed into Earth.
A large amount of plasmics with diverse backgrounds were aboard. Some were traveling for pleasure, others business, some to see family, others to get away.
Since landing, they have been quickly accepted into society and most of them are making the best of their situation. Although the Earth they’ve landed on is a bit more technologically advanced than real life Earth, there still isn’t science sufficient enough to get them home.
* While plasmics aren’t the dominant intelligence that developed space travel on their home planet, they are still very capable and intelligent, themselves.

Biology
Plasmics in their natural environment (e.g. back on their own planet) are mostly amorphous. They are devoid of defining features (no eyes, nose, mouth, hands, etc.). However, they are typically seen with a second mass floating above their main body. The humans have started calling it a “bouy,” pointing out that they bob up and down lightly.
On average, plasmics are nearly transparent. Though, some have been seen to be naturally more opaque. They also retain a specific base color for most of their lives. How the base color is decided or what changes it is unknown, but it has been seen to happen.
Their transparency and color can be temporarily altered by the food/drink they consume.
Bouy
The bouy is held up similar to how a human would flex a muscle. When a plasmic is holding up a bouy, their form is more solid. Their texture becomes closer to gelatin. When the plasmic releases the bouy and reabsorbs it, their form becomes more goopy, closer to slime.
The bouy’s purpose is to hold extra, unused mass away from the body while also helping to keep the plasmics chosen shape. The size and shape of the bouy is variable and depends on the plasmics needs / wants. Plasmics will release the bouy to begin shapeshifting. It will form again above them as they finalize their shape. Some plasmics have been documented holding a shape shift without a bouy, albeit with a far slimier and less solid texture. It appears to be a preference unique to each plasmic.
Senses
Plasmic senses are not like a human’s. They view the universe differently than we do, but they are very intelligent and highly adaptable. Their time on Earth has been enlightening to them and has given them much to enjoy.
Touch
A plasmics touch is their most important sense. They experience the universe mostly by touching, feeling, surrounding, or completely encasing things around them. It’s their most developed sense and is extremely accurate and sensitive. Similar to how a dog’s first thought is to sniff something new, a plasmic would be quick to touch it.

Sound
The way they experience sound is similar to humans, but it’s tied much more closely to their sense of touch. Sounds are just vibrations. Plasmics feel and interpret these vibrations with their entire body.
Loud noises (think a metal music concert) that cause deep vibrations in their bodies make it very difficult (but not technically impossible) for plasmics to hold their shape.
Sight
Plasmics are able to detect intensity and direction of light, but aren’t very good at focusing that into complex imagery. That is, until landing on Earth.
Before, it wasn’t much of a priority for them to see extremely well (mostly navigating with touch and sound). But since human society thrives through vision, plasmics have adapted their sense of sight to better fit in.
They are able to see with relative clarity at a moderate distance. They are comparable to healthy human eyes, with a tend towards near or far sightedness.
Taste
Plasmics sense the taste of things by touching or encasing them. Taste is not extremely important to plasmics in a survival sense. They don’t often worry about poison or rot. On their own planet, they didn’t much care for the taste of anything.
After reaching Earth, they were introduced to flavors never before tasted. Most plasmics love food and drinks, and are eager to try new things.
What they like or dislike is entirely dependent on the slime. However, its pretty unanimous across the species that clean water is delicious.
Smell
Plasmics lack a sense of smell entirely.
Nutrition
The species survives mostly on water and by dissolving the small amounts of minerals that get trapped in them through contact with the world.
Plasmics love water.
Earth has an abundance of tasty water: juice, smoothies, soda, milk, lemonade, sugary mixed drinks, teas, etc.
It’s extremely common for a plasmic to become attached to a specific “flavor” of water.

Rest
Plasmics don’t sleep. They are in a constant state of rolling rest. Since all of their cells can perform any function they need, a small percentage of their mass goes dormant to recover for a short period of time, and then will “wake up” and let a different set of mass rest. It appears that roughly 5-10% of their mass is “asleep” at all times. You could also see it like they are always 90% awake.
However, upon joining Earth, they were shocked to see that humans would spend ~8 hours a day just resting. Plasmics decided to give it a try with varying success / enjoyment.
Some plasmics forgo their rolling sleep in favor of human-like complete sleep. When a plasmic sleeps like a human, their entire body goes dormant at the same time, turning them into a puddle.
Plasmics that enjoy this have described it as “freeing” or “relaxation like they’ve never had before.” They will awaken later with more max energy than a plasmic with a rolling sleep cycle.
Plasmics that sleep like humans have quickly figured out the need for a bed and will often use containers like buckets, coolers, bathtubs, etc to sleep in. It’s common for plasmics that enjoy sleeping to brag about their choice of bed.
Language
Plasmics communicate in two different ways:
- Verbal language
- Touch (Information Sharing)
Verbal Language
Back on their home planet, plasmics would communicate by making and popping bubbles. They’d send vibrations at different volumes and frequencies. The sounds of which are incomprehensible to humans and mostly sounds like gurgling or talking underwater.
On Earth, they’ve learned to speak like humans do and are capable of communicating with clarity.
Their native language is referred to as “Plasmic” by humans.

Touch
Plasmics have a second, unique way of communicating. They can combine their masses (completely or partially) to transfer information. This information transfer isn’t perfect, and is likened to “reading one’s mind.” Its closer to a silent but quick conversation. So the accuracy of it depends on the ability of the plasmic to clearly convey the data.
When used on other species, the plasmic can “absorb” information about the their biology. This is harmless, and is simply like the plasmic is studying a living text book. This is how plasmics first learned enough about human senses and anatomy in order to mimic them.
Additionally, nearly every plasmic tends towards female presenting due to a misunderstanding in mammal DNA when they were first studied. All mammals start as a “blank slate” before the XX chromosomes develop into either XX or XY. Plasmics initially took this to mean female is the default presentation. Male presenting plasmics exist but are seemingly less common.
Shapeshifting
Plasmics are excellent mimics. However, it is limited by their knowledge and memory of the subject they are mimicking. The better the plasmic understands the target, the closer it will be to resembling it.
However, they cannot purposely change their color without assistance from outside sources (e.g. drinking cranberry juice to turn red, using food coloring, paint, etc).
For example, Jelli is rather lacking in knowledge and dislikes the idea of enveloping a human to study them. Therefore, her anatomy is based on what she sees and can sometimes be wonky since she watches a lot of anime and cartoons. Cream, on the other hand, really wants to fit into human society, going as far as ingesting opaque liquids to prevent being seen through. Therefore, her anatomy is far tighter.
