By 2012, John had become a detective within the New York City Police Department. One night, he was alerted that there was a recruit on Earth, that required orientation. So, John headed over the Metropolis and met Superman, the recruit.
What neither John or Superman realized was that their interaction violated a treaty between the Guardians of the Universe and Parallax. They soon found themselves attacked by Manhunters, that Clark destroyed on the Moon. Contacting the other Lanterns, John and Superman learned that Parallax still lived. Upon confronting it, they discovered that the Guardians had offered themselves to the creature. Just as they arrived Parallax expelled yellow Power Rings, to create his own Corps.
John and Superman attempted to trap Parallax, but the pressing problem with the yellow Power Rings forced Superman to leave and return to Earth. This left John to face Parallax alone. John did his best to fight the creature, but ultimately succumbed to fear and was taken over by Parallax.
As a vessel for Parallax, John returned to Earth and fought Superman. However, Emil Hamilton had managed to find a way to reboot all Power Rings (both yellow and green). This freed John from Parallax's control. The other members of the GLC arrived on Earth (having been outside the reach of the reboot signal) and returned Parallax to his original home.
With their Power Rings rebooted, John and the other Lanterns faced a choice about their future. They hadn't been given much choice, when they were drafted into the GLC. Now they had the right to choose for themselves. Ultimately, John and most of the others chose to resume their roles as Green Lanterns, becoming the New Guardians. Afterwards, John departed Earth to ensure that Superman's Power Ring would be issued to someone in the Kryptonian colony in Sector 2318.
When the Monitors attacked Earth, John was among the Lanterns that joined the heroes in Metropolis. After the defeat of the Monitors, John became a founding member of the team called the "Justice League".
