Dr. Light

Dr. Light is a DC superheroine distinct from the villainous Arthur Light who shares the name. Debuting in Justice League of America #61, she is a light-powered hero who has worked alongside Green Lantern, Batman, and Robin.

A Silver Age creation who first lit up the pages of Justice League of America #61 in 1968, this Dr. Light — distinct from the villainous Dr. Arthur Light who shares the name — emerged from the fertile imaginations of Gardner Fox and Mike Sekowsky at the height of DC's most inventive era. Over a remarkable publishing span stretching nearly six decades to 2025, the character has kept genuinely stellar company, sharing adventures with the likes of Green Lantern, Batman, Robin, and Dick Grayson, and appearing most prominently across Green Lantern, Flash, and the celebrated The Other History of the DC Universe. That last title alone signals a character worth seeking out — it's one of DC's most thoughtful explorations of its own legacy. Fourteen catalog appearances across 57 years tells the story of a figure who endures quietly but meaningfully in the DC tapestry, the kind of gem that rewards the dedicated collector willing to dig deeper than the marquee names.
