Splash page: Look, up in the sky...SUPERMAN, foreground, is reeling in pain, burning in the flames from the mouths of a three-headed dragon, which is flying out of a magical, bird-shaped portal. Riding on each of its necks, from left to right, are ETRIGAN the Demon, RAVEN, and JOHN CONSTANTINE. ETRIGAN is adding the hellfire from his mouth to the magical blaze, and JOHN is screaming into the sky with glee, fist pumping in the air. The pentagrammed eyes of TRIGON watch from beyond.
CONSTANTINE: ...Because SUPERMAN'S A WANKER!!!*
CAPTION (Batman): ...and Clark is helpless against more than just Kryptonite...
CAPTION: "Now I'm going home - in the distance, I can see them - Proudly waving flags to separate and free them..." - Bob Pollard (Guided by Voices)
*NOTE - The final line in Etrigan's rhyme, which Constantine finishes here, starts on Page 1 as follows: "The horrific reign of the Tyrant of Steel - O'er humanity is a tumorous canker - Thus let magick's might bring the Kryptonian to heel..."
