Krypto

Krypto was Jor-El's family dog on the planet Krypton, used as a test subject in an early rocket experiment before Krypton's destruction. His spacecraft drifted through space until he eventually reunited with Superman on Earth, gaining extraordinary powers under the yellow sun.

Few comic book animals have captured readers' hearts quite like Krypto, the legendary Super-Dog who bounded onto the scene in Adventure Comics #210 in 1955, dreamed up by the creative duo of Otto Binder and Curt Swan. A fixture of DC's Silver Age imagination — despite that 1955 debut placing him at the tail end of the Golden Age — Krypto has proven one of comics' most enduring four-legged icons, racking up over 226 catalog appearances across an astonishing seven-decade span stretching all the way to 2026. He's kept the very best company the DC Universe has to offer, sharing pages with Superman, Superboy, Supergirl, and Clark Kent across beloved titles like Superboy, Superman, and Adventure Comics, and eight of his appearances carry the weight of genuine key-issue status — a remarkable tally for any character, let alone a canine one. If you love the grand, wholehearted optimism that defines DC at its most iconic, Krypto is absolutely worth tracking down.
