The Silence are an alien race from Doctor Who. Their gender does not seem to affect their appearance.
Details
The silent are a race of humaniod aliens that have been on Earth since humans have discovered fire. They stand around 6-8 ft in hight and look like real-life slender-men(in fact they could be the source of slender man). One unique ability of the Silence is that the moment you turn away from them you instantly forget everything about them even looking at photographs once you turn away you forget about them. Even in public places they can remain unnoticed almost as if they are invisible. This ability is so effective that they do feel the need to carry weapons; however, they do have the ability to generate and shoot massive amounts of electricity with enough power to disinegrate a human at close-range.
Occasionally, some humans can remember a general "imprint" of the Silence, as displayed in such paintings as "The Scream". They are also more physically durable than humans; a Silence was able to handle two simultanious gunshot wounds at point-blank range directly at their chest and survive for a time afterward. They also possess superhuman strength-shattering reinforced glass and breaking through barricaded doors(that are over 2 feet thick) with ease. They also can breathe underwater though they can't use their electrical powers.
The Silence are shown to be wearing what appears to be full black buisness suit. They can influence and control humans by telling them a command, once the human turn their heads away from the Silence they subconsiously obey the command which has been implanted in their heads in the form of post-hypnotic suggestion; rumors have it that the Silence are what persuaded the U.S goverment to spend several billion dollars in order to put a man on the moon. Also if one becomes too exposed to the Silence he/she will be driven insane. They also appear to be able to cling to the ceiling like bats when sleeping.
