"Dr. Saul Erdel's teleportation device brought to Earth J'onn J'onzz, sole survivor of the plague that claimed his family and race.

A founder of the Justice League in all its incarnations, the Martian Manhunter's now up to the task - more specifically, Justice League Task Force." *Source: Card Back
