Following his resurrection, J'Onn J'Onzz returned to Mars, intent on reviving the planet of his birth. He had discovered a deep aquifer, and was intent on nurturing it. He also used his laser vision to claim a cabochon to wear on his chest piece, a symbol of his renewed connection to Mars. His pyramid home was visited by Green Lanterns Guy Garder and Hal Jordan, the former delivering a large stash of Chocos and milk. J'Onzz explained his plans to his comrades, who were surprised by his newfound optimism, and his continued commitment to Earth. While upset that his family had not returned with him, he was yet heartened by the revivals of Arthur Curry and Barry Allen.
