Homebrew Astral Plasmoid Species Details

Astral Plasmoids are amorphous beings with no typical shape. In the presence of other folk, they often adopt a similar shape, but there’s little chance of mistaking a plasmoid for anything else. They consume food by osmosis, the way an amoeba does, and excrete waste through tiny pores. They breathe by absorbing oxygen through another set of pores, and their limbs are strong and flexible enough to grasp and manipulate weapons and tools. Although most plasmoids are translucent gray, they can alter their color and translucence by absorbing dyes through their pores.

Astral Plasmoids are extremely mutable and are able to manipulate every part of their body at will. They can alter the fibers of their bodies to form interior pouches for carrying items, extrude limbs to use as legs, arms, tails, heads etc., and create air pockets that can be squeezed to produce sound. When a plasmoid sleeps or loses consciousness, it loses bodily rigidity and slowly oozes into a puddle conforming to the area within which it is contained. In certain situations this can be very dangerous for a plasmoid, thus they select their sleeping chambers with great care. Astral Plasmoids are able to change their color with dyes.

A plasmoid's nerve tissue is concentrated into masses known as ganglia. These can be sensitized to detect light, heat, texture, sound, pain, and vibrations. They can be partially exposed in order to adjust the sensitivity of their various perceptions. Thus, they could hear a butterfly up to 300 feet (91 meters) away, or totally cover these nerves to become effectively deaf. However, if they are listening to a butterfly and someone makes a noise as loud as normal speech, it is very likely that this will damage their ganglia, as they do not have the built-in protective responses which normal ears have. Thus they typically keep their senses at a normal (human) level and only alter them in extreme situations.

Astral Plasmoids do not have internal organs as normal creatures do. Their bodies are composed of fibers, generic cells, plasma-like ooze, excretion sacs, and nerves. They can manipulate their fibers to function as muscle tissue. Generic cells can form membranous linings, coverings, and cavities. These cavities can be used to carry items, or filled with acid for digestion and attack, food or drink, or liquid for rigidity, and air for bodily functions such as breathing and speech. A plasmoid speaks by forcing air out of a tubular cavity that constricts to produce sound. Plasma is used for the transportation of bodily fluids, energy to fibers, etc. Finally, their tiny excretion sacs convert digested food into chemicals – acid, energy compounds, etc. The only constant organ of a plasmoid is its brain, which is simply a giant mass of nervous tissue like a huge ganglia.

Astral Plasmoids breathe by absorbing oxygen through exposed plasma, meaning that part of their internal body must be exposed to air. They eat by enveloping food like an amoeba, and thus have no need for real mouths. Yet, it is not uncommon for them to form a mouth-like cavity simply to appease other races and to protect their plasma. Since they can store air within their bodies, they can "hold their breath" for up to an hour. Furthermore, their immunity to poison and other toxins enables them to endure poor air quality better than other living creatures.

Most plasmoids have the ability to form some type of bodily coating or skin. This coating and its use varies from one species to the next. Plasmoids excrete by oozing bodily waste products from their pores. They tend to do this constantly, which produces a slime trail wherever they go. Since they don't detect odor, they have a hard time understanding other races' revulsion to this act.

All plasmoids reproduce by joining with another of their species, exchanging genetic material, and then at any later time (from instantly to years in the future), they simply divide in half. One of the plasmoids is the original; the other is a near duplicate except it starts with only basic skills and knowledge (whatever the parent could spare).

Astral Plasmoids can alter their mass and weight as well as their form. This is done by absorbing a lot of food and drink and growing just as a water balloon does. They can manufacture more fibers, nerves, and cells to accommodate their larger size. Of course this takes time, just as it takes time for a human to gain weight. Shrinking is nearly instantaneous though; the plasmoid simply divides, leaving a blob of unwanted material behind. A large plasmoid can last for several months without eating, but it must absorb liquids at least once a day or it will dry out.

Because plasmoids can alter the arrangement of their fibres, they can also adjust their strength. If they put all of their fibers into one large muscle, they can lift massive weights. Astral Plasmoids are all very heavy because of their liquid content.
