To people that are confused about the ending. The character showed up in the end was the actual Monkey King. If you are slightest familiar with "Journey to the West", I bet you are confused how can there be two Monkey Kings? Well here is a possible theory and some backgrounds. The answer lies in the story the studio is trying to tell which may be lost in the translation of the trailer. At the end of "Journey to the West"all the four main characters obtained Buddha status, or some form of godhood. In doing so, they must abandon their corporal carcasses. The story of the game picks up after this. From the dialogue of the NPCs you can see, they recognize the resemblance of the player controlled monkey with the legendary Monkey King, Sun WuKong. They keep saying, "you really look like him!" or "another monkey", which means they either have heard of seen him before. So, it is possible, the main character that is the player through out the game, is the mortal flesh which the King abandoned in obtaining his godhood. Since WuKong the Monkey King was born from the sky and earth through a sentient stone, this mortal carcass he left behind retained a lot of life, also the sins during his mortal life. Hence, the name of the game "Black Myth". After all, what greater enemy is there if not oneself?! PS: last four characters out of eight of the trailer , literally says “revisit the journey to the west”, which implies the original journey to the west was completed.
