Publisher’s description

KYLE RAYNER BRINGS THE COSMIC REINFORCEMENTS! As the K.O. tournament rages on Earth, the cosmos holds its collective breath as the heroes of our planet fight for the survival of the very universe. But the cavalry is on the horizon! Kyle Rayner, in a bid to provide cover for his fellow Green Lanterns, has found himself pummeled across the galaxy and into the ring of... a wrestling federation?! Oh no... oh dear heavens no... is Omega Bam Man about to enter the DC K.O. fray?! Oh mah gawd! An entire cavalcade of brawlers is right behind him! Are there tables? Somebody get the tables!
