Answering the Call (GREEN LANTERN vol. 5, #13-16, 2012-2013)
In his earliest appearances, Simon Baz inherited his role as Green Lantern from both Hal Jordan and Sinestro, who’d recently returned to the Green Lantern Corps. Both Lanterns had ended up in the realm of the dead, and due to their absence from this plane, their rings combined into one new, unique ring, which chose Baz as its bearer.
This event transpired in the middle of a cosmic crisis known as the “Rise of the Third Army.” The Green Lanterns’ creators and wardens, the Guardians of the Universe, had in eons past created an army of androids called Manhunters as their cosmic peacekeeping force. When this force ultimately failed, it was replaced with the sentient Green Lantern Corps. Now the Guardians sought to replace all Lanterns with a third police force, made of beings stripped of their free will, who functioned as extensions of the Guardians’ own.
In the midst of this crisis Baz received his ring. With his new powers and abilities, Baz proved himself a worthy successor to Hal Jordan, and to heroes like Superman and Batman, as he fought off an army created to replace him and others of his kind.
Joining the Justice League (JUSTICE LEAGUE OF AMERICA vol. 3, 2013-2014)
Not long after joining the Corps, Simon Baz was asked by intelligence operatives Steve Trevor and Amanda Waller to be the United States government’s resident Lantern in the newly formed Justice League of America. Waller offered to clear all charges against Baz in the terrorist incident for which he was mistakenly arrested, an offer he couldn’t refuse.
This version of the League, despite heavyweight members like the Martian Manhunter and Hawkman, did not last long, and was disbanded shortly before the events of the Trinity War, which saw the emergence of Earth-3’s Crime Syndicate on the Prime Earth.
Earth’s Sole Lantern (RED LANTERNS #24, 2013; GREEN LANTERN #29, 2014)
When former Green Lantern Guy Gardner was a member of the Red Lantern Corps, he made Hal Jordan promise to leave Sector 2814 to the protection of the Red Lanterns and forbid all members of the Green Lantern Corps from entering this area of space.
Though the sector was free of the Green Lanterns’ presence, Hal Jordan made one exception—Earth would remain under the protection of Simon Baz. As a sign of the newfound respect Jordan had for Baz, the veteran Lantern placed his own family in Baz’s care.
Following the events of DC UNIVERSE REBIRTH #1, Baz was assigned by Corps leader Hal Jordan to train rookie Green Lantern Jessica Cruz, despite the fact that he had only slightly more experience than she did. After the two Lanterns disappointed Jordan in their performances during a training exercise, Jordan chose to fuse their power batteries into one.
This new battery can only be accessed when the two are in the same place, a move Jordan hoped would bring them together as a team. Although at first the two rookies grated on each other’s nerves, they eventually bonded, becoming close friends and partners.
At this time, Jordan appointed both Lanterns to membership in the Justice League, hoping his former teammates would help train them. Baz’s teammate Batman, a hero with no love for firearms, then convinced him to give up the gun he’d always kept at his side.
