The eldest Jordan brother, Jack has been voted the D.A. for Coast City, a position that has made him a target for criminals. He would be saved countless times by the Green Lantern who is secretly his younger brother Hal Jordan.
The modern era would establish that prior to his death, Jack was on bad terms with Hal, due to Hal breaking the promise to their mother not to follow in their father's footsteps. After their mother died, Jack never forgave Hal, blaming that his recklessness had shortened their mother's life causing her to die out quickly.
After Hal died and took on the mantle of the Spectre, he appeared to Jack and Carol Ferris as a ghost. Hal sought to reconnect with his brother, but Jack's wife Jan protested, claiming that Hal had changed into something unrecognizable. A short time later, Stigmonus kidnapped their daughter Helen. Jack and Jan attempted to find her, but Stigmonus caused them to crash their car. Both died of their injuries.

However, some elements of the character's Pre-Crisis history may have been altered or removed for Post-Crisis New Earth continuity, and should be considered apocryphal.
