JLA: Ultramarine Corps

Grant Morrison and Ed McGuinness teamed up for this single-issue DC special from 2007, a spin-off spotlighting the bizarre, multiversal super-team introduced in JLA: Classified. The book expands on Morrison's cosmic-scale storytelling, giving the Ultramarine Corps—a group of heroes from an alternate Earth—their own moment to shine. It's a compact, high-concept blast of Morrison's signature weirdness, anchored by McGuinness's bold, energetic art.
