David 8
David was an android commissioned and built by Sir Peter Weyland. He would serve as the basic template for the David 8 and Walter model lines, but was apparently himself unique, possessing creative and emotional capabilities in excess of commercial models.[3] In 2091, he was assigned to the crew of the USCSS Prometheus for its mission to LV-223, and was one of the two survivors of the disastrous expedition, along with Dr. Elizabeth Shaw.
David would go on to discover Planet 4, where he would live alone for a decade after committing genocide against the species that inhabited the planet, carrying out genetic experiments involving the black liquid mutagen and seeking to create the "perfect organism". He was later discovered by the crew of the colony ship USCSS Covenant, and ultimately hijacked the vessel for his own ends.
