Foreground, RUDOLPH, surrounded by a red aura, spewing blood from his mouth and suited in black, a red domino mask about his eyes, and his glowing nose bearing the sigil of the Red Lanterns:

He is flying toward us, screaming his own version of the Red Lantern oath (below)
Background: On a snowy, starry night, high above the world, Green Lantern GUY GARDNER has used his ring to rescue SANTA CLAUS, and another energy beam has caught his sleigh and its giant, overflowing bag of toys sticking out the back. SANTA is relieved, but worried, as his other reindeer are nowhere in sight. GUY with a fiercely determined look on his face, has also manifested an emerald-energy cookbook titled "101 Holiday Recipes for Venison" and barbecue tools.
SANTA: No, Guy! Don't! You just made the NICE list this year!
GUY: Sorry, Mr. Claus, but there's no other way!
RUDOLPH: Dasher and Dancer and Prancer and Vixen!
Comet and Cupid and Donner and Blitzen!
CAPTION: They laughed at him. They called him names. They wouldn't let him play any reindeer games...
CAPTION: Now, they're going to pay...
