Batman / Hellboy / Starman #1

Three unlikely heroes converge in this 1999 DC/Dark Horse crossover: Batman lunges forward from the shadows above while Hellboy charges fists-first at center, and Starman strides alongside gripping his cosmic rod — all rendered in Mike Mignola's unmistakable angular style. Lurking at the edges are a grim Nazi figure and a small, unsettling jester, hinting at the strange and sinister forces the trio is up against. Writer James Robinson and artist Mignola make for a genuinely compelling creative pairing, and "Gotham Grey Evil" promises the kind of pulpy, atmospheric adventure this cover delivers in spades.
