Justice League Unlimited #9

The golden-skinned sorceress Morgaine le Fey dominates this cover, looming triumphantly as the heroes around her — including a dazed Zatanna sprawled in the foreground and a struggling Superman — look decidedly worse for wear, with a sword-wielding armored warrior and a scarlet-clad figure also caught up in the chaos. Ben Caldwell's animated-style linework captures the Cartoon Network aesthetic perfectly, bringing real menace to Morgaine's gleaming, red-eyed grin. "Castle Perilous" promises exactly the kind of magical mayhem that makes Justice League Unlimited such a treat, and this 2005 issue delivers a villain who clearly means business.
