Doctor Vargas

History
The Doctor is a leading weapons developer for the human coalition in Knack. Due to the war with the Goblins, humanity is desperate for any edge that will grant them success and survival, and The Doctor is one of those edges. To the surprise of many of his colleagues, The Doctor offers his artificial intelligence construct, Knack, as a weapon in the war against Gundahar and the Goblin armies. Because he is seen helping Knack throughout the reveal trailer, it is assumed that The Doctor will be an active protagonist, as opposed to a passive background character. The Doctor is also principally responsible for raising and caring for Lucas, as Lucas' parents are deceased and his uncle is a globetrotting adventurer.
