Astarte_

Astarte was sent aeons ago to a far away planet. As she flew through space in her artificial slumber the solar winds of an unexpected supernova explosion blew her off just a tiny bit. However it was enough to miss her original target, and she flew seemingly endlessly through space. Eventually she smashed into a barren planet where she continued to sleep. Over millions of years the planet became filled with life, and more and more complex living organisms developed. One day, the inhabitants of the planet developed such a strong consciousness that is awoke Astarte. Even though she has ended up on the wrong planet Astarte will still fulfill her original assignment: Subjugate all life forms, assimilate useful genetic information to her own to strengthen her race, and eventually construct a portal to her homeworld so the planet would become part of their empire. Astarte is a tall dark-violetly skinned female humanoid. There are conflicting reports about her height, some describe her as being two meters tall (~6'8"), others as four meters tall. The reports state that her skin, while seemingly looking soft and smooth, is hard as a shell at most parts of her body. Each hair on her head is several centimeters thick (~1"), sturdy and about half a meter long (~1'8"). Four tentacles emerge from her lower back, and they seem to be able to stretch out indefinitely and can disappear into thin air at will. Eyewitnesses state that she can lift and even throw heavy objects such as vehicles, and constrict and subsequently squash even the quick armor of a tank. TL;DR: An alien lifeform that was sent to this planet to improve itself and eventually subjugate the entire planet. Astarte has, as all beings of her race, immensively powerful psychic / magic abilities.
