Diana Trevor

Few characters carry a name as resonant as Diana Trevor's within the DC universe — and with a debut in the landmark DC 100-Page Super Spectacular #6 in 1971, courtesy of the legendary team of Gardner Fox and Mike Sekowsky, she arrived during the Bronze Age with real weight behind her. Though her catalog footprint is selective, her appearances span a remarkable 54 years, touching titles like Justice League of America and All-Star Squadron, and two of those issues carry key-issue status that collectors rightly prize. She keeps extraordinary company — sharing pages with Wonder Woman, Superman, Green Lantern, The Flash, and Hawkman — which tells you everything about the tier of DC storytelling she inhabits. A character this quietly persistent, in this kind of company, is exactly the sort of discovery that rewards the dedicated reader digging deeper into DC's rich history.
