Green Lantern Power Ring (Earth-Prime)

"How'd you get it open last time? That's the problem. I didn't do anything. It just opened for me. So maybe the key to opening that box isn't based on science, human or otherwise. Maybe it's... something else entirely."

- Luke Fox and John Diggle

The Green Lantern Power Ring is a glowing object that crash landed on Earth.

Choosing John Diggle
In 2020, John Diggle started packing and moving to Metropolis. He then witnessed a meteor shooting across the sky and landing in front of him, sending him flying and hitting a truck. John opened the box and revealed a glowing Green Lantern Power Ring.

Repercussions
A year later, John started hearing voices in his head after he refused to accept the call. He travelled to Gotham City in search for answers from the hospital's neurological department. However, it was unsuccessful and John suffered from headaches during his trip to Central City. According to Cecile Horton, there were "infinite" voices in John's head telling him that "worlds await".

A Fighting Chance
Despite hearing voices, John was unable to open the ring's box since its arrival. He then handed the box to Luke Fox in hopes of his "Battech" would be able to unlock it. Unfortunately, Luke was unsuccessful and soon returned the box to John, telling him that the technology does not seem human to him after apologizing.

Functions

 * Glowing: When John opened the box, the ring glowed green and fascinated him.
 * Connection to the "Voices": After John refused to accept the ring, he started hearing infinite voices in his head, which is not a neurological problem as doctors seemed to find no problems with his brain.
