The Captain (whose real name is unknown) is a minor character in Deliverance. He is the captain of the Marauder, and also the protagonist's father. He leads his crew in travelling the galaxy searching for a Cure for The Emperor.
The conversation with The Captain reveals him to be somewhat pompous and not exceptionally intelligent, but very jovial and perceptive, making it likely that he acts as a father to all his crew, not just the protagonist. A throwaway line reveals that the death of his wife on an away mission still haunts him to some extent. He speaks in a rather antiquated manner.
