A'lars was the second son of Chronos and Daina, two of the first generation of Eternals, and was born eons ago in the city of Titanos. A'lars and his brother Zuras were raised in the aftermath of the great civil war which divided the first colony of Eternals. Their father Chronos, who was on the winning side of the civil war, toiled away in his laboratory attempting to discover the secrets of the self-regenerating cosmic life force that he felt his race was capable of attaining. A force field cylinder containing cosmic energy exploded, disintegrating Chronos' body and imparted immortality to all nearby Eternals. A'lars then became a scientist like his father.
