Oscha

Oscha were the rare result of humans being exposed to Warclema's physical laws before obtaining the necessary adaptations. They lost a permanent, organic form, and the ability to survive within the physics fields made by humans, but gained the ability to shape shift.

Oschan Shape Shifting
Oschan bodies are made up of an inorganic slime that can be controlled by nearby brain signals. This slime is believed to be made up of a special particle that is able to act as either a proton or neutron in response to certain electrical signals while exposed to Warclemian physics. This allows such a substance to mimic all kinds of other substances, both organic and inorganic.

The brain signals needed to control an oscha's body require a good amount of concentration to maintain, and a lapse in concentration will cause part of the body to revert back to its natural state until the concentration is restored. An oscha's brain will usually provide the concentration to keep it's form involuntarily, but is still susceptible to damage, whether through trauma or lack of nutrients.

Oscha are almost never able to concentrate on their form well enough to completely avoid any part of their body reverting, so they are very reliant upon their nervous system to alert them to which parts have reverted. This and their ability to shape shift damaged parts into undamaged parts have led to them handling physical pain rather differently than humans do.

Oscha as Symbionts
Oscha are often unable to keep a complex form for long, ad so, they will often build themselves around other objects to provide body parts that they don't need to concentrate on. The simplest example of this behavior would be an oscha forming a skeletal system out of rocks and sticks. They might then go on to use strips of bark or grass to help form simple muscles. Often though, they will make use of the bodies of other creatures. Oscha usually make use of a mix of body parts from different creatures. There are those however that will use an entire creature, sometimes while it's still alive.

Using a host body will often greatly reduce the amount of concentrating required to keep a form as they only need to maintain connections to the host's circulatory system to obtain nutrients. As the oscha learns more about how the host's body works, they will often try to move towards a more mutualistic relationship. They will start a mutualistic relationship by repairing small cuts and bruises and move on to whatever they think can help their host, whether it be extending limbs, redistributing body fat, providing extra grip, or anything else they can think of. A few times, the host will learn to create the brain signals that control an oscha's shape shifting.

Because of an oscha's common reliance upon other organism's bodies, whether the organism is still alive or not, other species will often view them as parasites.

Oschan Reproduction
Oscha's also use their shape shifting ability to reproduce. Two or more oscha will come together to try to form a new brain through shape shifting. That new brain will slowly learn how to form a body out of oscha slime, but until then, it will rely upon another oscha to act as a host body to it. Oscha can also use this method to reproduce with another species that has learned how to control oscha slime, but the result will always be another oscha.
