Justice League Unlimited #41

Harley Quinn brandishes a lit bomb with mischievous glee while the Joker looms large in the foreground, his wide grin promising chaos — all set against a dramatic view of Earth from orbit on this 2008 issue of Justice League Unlimited. In the background, two more villains — one in a red coat and top hat, another alongside him — look ready to join the mayhem, making the cover's tagline "Party Out of Bounds!" feel entirely appropriate. Cover artist Zach Howard brings the animated-series style to vivid life, and with a story titled "The Anniversary Party," this issue looks like a delightfully unhinged celebration of villainy.
