Sayan

Sayans are a race of aliens featured in the Anathemus Mythos who have thus far only appeared in the Xat RP.

Appearance
Sayans are very inhuman in their appearance. The only Sayan described so far was a giant mass of distorted flesh lacking any natural openings except a massive vertical mouth. It also had tentacles used for locomotion and catching prey.

Sayan blood seems to be incredibly malodorous.

Attributes
The primary purpose of a Sayan is reproduction. To that effect, members of the race infiltrate planets and attempt to initiate sexual contact with male members of local species. Upon acquiring male sperm, a Sayan analyzes its genetic makeup before bursting into a cloud of spores, this kills the Sayan but eventually mutate inhabitants of the planet into new Sayans.

Since Sayans are physically repulsive to the sight of almost all sapient species, they possess a special ability to assist them in their task: namely, the ability to psychically alter their targets' senses. Usually, a Sayan will use this ability to appear to its designated victim as a beautiful girl and attempt to incite coitus, though male disguises are also feasible. A Sayan normally requires physical contact with a target prior to being able to use its mind-altering abilities, but they can also spread clouds of spores which can substitute physical contact.

Sayans are able to read the mind of the victim just as well as they can rewrite it, and will often use that to assume the form of someone dear to the victim.

Members of the Sayan race are significantly stronger than humans and possess immense durability, enough to withstand most attacks without sustaining any harm.

In addition, Sayans secrete a terraforming substance which is able to slowly convert anything in direct contact with it into more of itself.

Trivia

 * Sayans are inspired by and even named after the titular character of the visual novel Saya No Uta, which depicts an extradimensional entity with a similar goal.
