Non canon and a completely rookie Kyle. Surfer also said he was not sure if he could beat Kyle even at full power.
Superior power set? More powerful? Greater Strength? GL ring can do ANYTHING. He has contained a supernova in his hand, surfer has no feats in that class. Kyle also restored Earth's orbit by his hands when it was spiraling out of control, give me a strength feat comparable to that from surfer.
According to what superman said and what was shown on panel, kinda looks like kyle just repaired some of the damage parts and held the existing structure together.
Surfer beat Mrrungo Mu who had the power of billions of enslaved aliens from thousands of worlds as well as the powers of most of Earth's heroes and villains. On panel Mu absorbed the powers of Thing and Thor iirc [might have been Colossus or Namor though, been awhile since I've read The Enslavers], then he put the rest of Earth's superhumans in pins that drained them of their powers and fed their powers to him.
Just for reference, his construct was sufficient to:
a.) Fully encase the moon of earth 2.
b.) Imprison the entire CSA for 48 hours. ie. Not even the infinity-lifting Ultraman, or Owlman(a guy arguably smarter than Batman himself) were able to breach the construct.
You might also note that the CSA's version of Green Lantern had his ring analyze Kyle's construct... The ring stated that it was "impenetrable."
and kyle managed to put up a shield to protect himself alongside the platform that he was standing on, while everything else (including the planets) got destroyed
Green Lantern: New Guardian, isn't it? That's totally insane. Do you have the scans of Kyle absorbing that black hole which was absorbing the sun from GL 167 or something?
