David is the leader of a group of survivors and an antagonist in The Last of Us. Nothing is known of David and his group prior to Ellie encountering them at the Lakeside Resort.
Ellie is suspicious of David and his friend James at first, demanding that the dead deer is hers and she will trade it for antibiotics. After being attacked by infected, David knocks Ellie out and takes her back to his settlement. David offers Ellie a spot in the group, creepily implying that he wants her sexually, but she escapes and eventually kills him.
