Alien (The Forgotten)

This unnamed humanoid species appears to be in control of Earth, manipulating the Human population for various types of experiments.

Biology
The aliens are humanoids who bear a mostly Human-like external appearance. However, their craniums appear somewhat enlarged, and their eyes are entirely black, sunken into their heads like semi-skeletal eye sockets. They are capable of at least minor shapeshifting, able to hide their alien features and take on a perfectly Human-like outer appearance. Internally, their bodies appear to be almost metallic, or possibly liquid, only appearing grey with no blood. They have been able to walk away from being struck by cars completely unharmed, displaying some sort of super durability, although bullets are able to pierce their skin. When pierced, at least by bullets, the alien's skin appears to smoke. Notably, they are able to heal in a matter of seconds, with the wound no longer smoking once healed, and appear to feel no pain. In addition, direct hits from bullets do not make them fall or even flinch. The aliens also have the ability to create shockwaves with the sound from their speech, able to blow adult Humans away and shatter glass in a fairly large radius. Most notably, they are able to erase years worth of memories from Humans, appearing to read minds of victims, seeking a "source memory," and able to remove an entire type of memory while possibly adding in false memories, such as removing the memory of one's children. However, this ability has its limits, unable to overcome parental instincts and bonds. Certain items or other memories connected to the erased memories can override the erasure, restoring the memories.

Culture and society
Little is known about the alien society. They are known to effectively take over planets, and then proceed to run various experiments on the population, conscripting local governments to support them, with no apparent reservations about harming sapient beings. A Human agent claimed that complying with the aliens is the only way to protect mankind, implying that the aliens would destroy a planet if they meet mass resistance. To avoid this, they only met with government officials, and keep themselves hidden from the general public. They appear to have a radically different concept of parental love, or possibly no concept of it, although they believe they can tangibly measure it. If their experiments fail, the tester will be punished, presumably for wasting their resources.

Technology
Little is known of the alien's level of technology, as none have been directly seen by Humans, but they appear highly advanced. The only example of their technology in action, or at least what is presumably their technology, is their abduction technology, which appear to be some sort of invisible tractor beam, capable of violently sucking a target into the air, presumably towards one of their ships or facilities.
