Summer Day

Few characters carry quite so unusual a birth certificate as Summer Day — debuting in Cancelled Comic Cavalcade #1 in 1978, a Bronze Age DC curiosity born from one of comics history's most offbeat publishing experiments, courtesy of Gerry Conway and Dick Ayers. Over the decades she's carved out a quiet but persistent presence, racking up appearances across The Fury of Firestorm, Firestorm, and The Flash, sharing pages with heavy hitters like Firestorm, The Flash, Batman, and Green Lantern — genuinely elite company by any measure. With a publishing footprint stretching all the way to 2025 and a key issue already to her name, Summer Day rewards the curious collector who loves digging beneath the surface of the DC universe to find characters with real staying power and a wonderfully unconventional origin story.
