Kyle Rayner's new feature title Green Lantern: New Guardians
establishes right off the bat that this is the Kyle Rayner fans know and love. There was a time when all the Green Lanterns (and most of the Guardians of Oa) died/were gone, and Kyle received what was at the time the last, the only Green Lantern ring.
Jumping back into the present though, is where the mystery comes from. Throughout the first issue we see rings across the spectrum, a Red ring of rage, Orange of avarice, Yellow of fear, Blue of hope, Indigo of compassion, and Violet of love all up and fly away from their current ring-bearers (resulting in injury or worse for many). Every one of those rings shows up in Sector 2814, proclaiming "Kyle Rayner of Earth, You have been chosen."
The question then of course is, why do all the rings want Kyle Rayner? Is it something about his ring (assuming in this new continuity this is still the same "last/first ring")? Does Kyle, with his artistic mind and emotional moments, have a unique constitution ready to accept every color? And of course, if all these rings actually make it onto Kyle's fingers, what will that emotional overload do to him? These are obviously questions DC wants us asking, but they're nonetheless intriguing.
