The scene: Kyle Rayner has been Green Lantern for about 10 minutes, but the dreaded Mongul has shown up, and he's in the mood to kick some Green Lantern ass, and he doesn't care if it's Hal Jordan or some rookie.
Fortunately for our inexperienced hero, mullet-wearing Superman shows up to help. Less fortunately, despite some good blows, Supes is unable to gain the upper hand.
Well, since this is Kyle's book, he gets to deliver the knockout punch, right? So how do you take down the pissed-off-and-as-strong-as-Superman intergalactic conqueror? One word, baby:
Now that is officially a KNOCKOUT.
Fortunately for our universe, Bahlactus has no "necessary impurity" in his ring!!
Kyle's version of Blood on the Tracks comes from Green Lantern #53.
