Jerro

Jerro is a young Atlantean who became a romantic interest for Supergirl during the Silver Age, inhabiting the underwater world of Atlantis. His aquatic origins placed him naturally within the Superman mythos as a denizen of the seas.

Splashing onto the Silver Age scene in Action Comics #276 (1961), Jerro is a DC Comics figure whose debut — crafted by Robert Bernstein and Wayne Boring — planted roots deep in the underwater corners of the Superman mythos. With a catalog presence stretching across an remarkable 64 years and three key collector issues to their name, Jerro has proven quietly enduring, surfacing across Action Comics, Adventure Comics, and Countdown in the company of some of DC's brightest stars — Superman, Supergirl, and the telepathic Imra Ardeen among them. It's a rarefied circle to swim in, and for fans who love the rich, imaginative world-building of the early Silver Age, Jerro is exactly the kind of hidden gem worth diving after.
