If possible I want to use a custom race. It's not finished yet but this is the basic premise~

Race: Nix’teoin (human host, female, 23)


Overview - Nix’teoin are a race of small amorphous biomasses that possess limited physical capabilities and instead take control of host bodies through entanglement of the hosts spinal column and brain (or analogues of such systems).

Planet of Origin – Arnak

Natural Environment - Oceanic Twilight Zone

Social Structure – No social structure of their own and will often assimilate into the social hierarchy that their host body belonged within.
Physical Traits (Nix’teoin) – As an amorphous biological mass their physical capabilities are non-existent, possessing virtually no motility and very limited sensory capacity. Therefore the physical traits of the species is defined by that of the host species which the Nix’teoin are bound to, only improved due to the Nix’teoin’s ability to modify its host. This results in a ‘better’ version of the original host, with enhanced physical and mentally capabilities.

Mental Capacity – Astounding, originally leading to the theory that the Nix’teoin were designed as a form of highly efficient biological processor for a type of technologically that combines organic and nonorganic components. It is for this reason that Nix’teoin will crush the psyche of virtually any host organism, even when subjected to inhibiting factors. Despite fears to the contrary Nix’teoin cannot ‘steal’ memories from their hosts as the implantation process usually destroys the hosts memories.

Reproduction (Nix’teoin) – Unknown for Nix’teoin themselves. Nix’teoin within a host can reproduce with other individuals of the same host race, producing normal, healthy offspring of that race.

Diplomatic Status – Officially allied with the Union, however there are always rogue elements that have different motivations.

Age: Uncertain

Gender: Neither

Appearance: Nix’teoin themselves are not organisms that can be easily described or differentiated by most species, so for that reason they are often described in terms of their host and their chosen name.
