David, originally manufactured as David-8, is the main antagonist of the 2017 sci-fi horror, Alien: Covenant. Due to being the creator of Xenomorphs, David is the overall true main antagonist of the series. David was portrayed by Oscar-nominated actor Michael Fassbender, who also portrayed Magneto in the last X-Men movies and Lord Macbeth in 2015 version of Macbeth.

Background
David was created by Weyland Industries on special orders from Peter Weyland himself, who wanted to use him in Prometheus expedition, which goal was to find mankind's creators, the Engineers, so Weyland could ask them to make him immortal. From the very beginning, David started to feel superiority to Weyland because of his own immortality, and seeing him desperately asking for it from the found living Engineer only established his thought that he is superior to Peter, and cause Peter is the best of all mankind, David started to think that he is superior to all mankind as well.

Covenant: The Haughty Creator
He started to think of humans as dinosaurs, while robots and the new life forms like Aliens were the future in his eyes. Events he encountered with Elizabeth Shaw and her crews did not help him think otherwise either. So when he was restored after the serious damage from the Engineer by Dr. Elizabeth Shaw (revealed to have died in Covenant), he arrived on the Engineers' planet, the so-called Paradise, and destroyed all of them, and when it was done, he started his mad experiments on the virus founded by Prometheus mission. He created various different beings, even using Shaw as one of his experiments, but the final result of his work was prototype Xenomorphs, a highly hostile and aggressive predator species which would evolve to become the infamous antagonist creatures of the franchise overall that mankind would encounter in years to come.
