Sonar

Emerging from the Copper Age of DC Comics, Sonar made their debut in the pages of Green Lantern #201 in 1986, introduced by the celebrated creative team of Steve Englehart and Joe Staton. This character's story unfolds in the orbit of some of the most iconic figures in DC's cosmic corner — sharing adventures with Hal Jordan, John Stewart, and Katma Tui — placing Sonar squarely in the rich, ring-slinging mythology of the Green Lantern universe. With appearances across Green Lantern, Green Lantern Secret Files, and Secret Origins, and at least one collector-recognized key issue to their name, Sonar may have a compact catalog footprint but carries the unmistakable stamp of a character born from one of comics' most imaginative eras. For fans digging into the deeper cuts of late-'80s DC, Sonar is exactly the kind of discovery that makes back-issue hunting so rewarding.
