Father Time is the embodiment of the primordial time and existence as a whole. Time is the father of The Endless.
Time is constantly changing from a young boy to a middle-aged, then elderly man in a random pattern.
Time is particularly lonely, although he prefers it so, as he does not want to have any contact with his own children. To his mind, the only reason any of his children visit him is because they want something - besides Destiny, who asks nothing of him because Time gave him all he had as his birthright. Destiny leaves him alone.
The one person he is interested in meeting again is Night.
