Skrulls! #1

A menacing Skrull face dominates Greg Horn's cover for this 2008 Marvel one-shot, those jagged amber teeth and burning orange eyes making it clear exactly who — or what — has been hiding among us. Tied directly to the Secret Invasion event, this standalone issue spotlights the shape-shifting alien race at the heart of Marvel's conspiracy-fueled storyline. Horn's painted rendering gives the Skrull an unsettling realism that perfectly captures the paranoid tone of the era.
