Justice League Unlimited #23

Titled "A Royal Pain in the Neck!" right on the cover, this September 2006 issue of Justice League Unlimited puts the Royal Flush Gang front and center — Ace, King, Ten, Queen, and Jack posed menacingly amid a shower of scattered playing cards, with hero cards featuring Superman and others tumbling around them. Ty Templeton's cover art captures the gang's card-themed swagger against a vivid yellow background, making the threat feel both colorful and genuinely dangerous. Writer Mike McAvennie and artist Leigh Gallagher bring the Cartoon Network animated universe to the page for fans of the show and comics alike.
