Swamp Thing #37 (DC, 1985) is the first appearance of John Constantine, introduced by Alan Moore, Stephen Bissette, and John Totleben during the most acclaimed run in the title's history. Constantine went on to anchor Hellblazer — one of the longest-running mature-readers titles ever — and this debut has become the definitive Copper Age DC key.
